Neighborhood Walk

I went for a lovely walk in the lovely neighborhoods of Sherborn, MA with my family. The weather was partly cloudy, in the mid sixties and walked for about forty-five minuets during dusk. The area is a thick wooded swamp area with lots of natural brush and trees. My mother-in-law, who is a professional landscape designer, was very informational on the native plants and trees. We enjoyed talking about the various specific identities to each plant as well as how common they are or how invasive. One of the most interesting thing that I learned is the distinct bark on the Winged Euonymus, where it grows out in a point that forms a wing shape giving it's common name. I learned a lot and was glad to find so much plant diversity right here in my local neighborhood.

Popup Mycoblitz this Saturday, 10-12

Now that we are finally seeing the steady appearance of a variety of early summer fungi, I calling for a loose collective popup GW mycoblitz this Saturday morning. We will meet at the PPW (not the Arch) entrance at 10AM and spend a few minutes reviewing observation techniques. Beginners are enthusiastically encouraged to attend -- if we have the right mix we will buddy-up beginners with experienced searchers. We will meet back at PPW at noon to review our finds.

Hope to see you there. If you have any questions or concerns, reach out to Sigrid (@sigridjakob ) or me (@pcpalmer3).

MMM de Cancún

Lunes 14 de Junio de 2021, aproximadamente a las 16:00 pm, un movimiento MIGRATORIO MASIVO de mariposas se manifestó. Las especies dominantes eran Eunica monima, Eurytides philolaus, Libytheana carinentha y Marpesia petreus, y con algunos piéridos, y unas saltarinas que creo que eran Proteides mercurius, todo un espectáculo que no había visto en años. Comenten abajo que opinan si es que de casualidad ven esta nota.

Observation of the week – June 5-11, 2020

Our fifth observation of the week is this Silver Spotted Skipper seen by Nick (@nickuzhov) on the Elora Cataract Trail.

Silver Spotted Skippers have a large proboscis (i.e., tongue) – which is very visible in this photo as it is wedged into the clover flower. They are often seen visiting flowers, especially pink and purple ones, and spotting them while they are drinking nectar can be a great time to take a photo. Nick agrees, saying “it wasn't a troublemaker and allowed me to take the picture easily”.

Though Nick has been taking photos of butterflies for over a decade, he started in Russia and is still learning Ontario’s species. This was his first Silver Spotted Skipper, and he was helped in putting a name on it by the iNaturalist auto-ID feature. Silver Spotted Skippers are the largest skipper butterflies in Ontario. Their size, in combination with the bright orange band on their forewings and large silvery white spot on the underside of their hindwings, make them distinctive.

Silver Spotted Skipper caterpillars eat plants in the legume family (Fabaceae), including American Hog Peanut, American Groundnut, and Showy Tick Trefoil. They also love Black Locust Trees. Some people think that the Silver Spotted Skipper may have been uncommon or even absent from Ontario and other parts of northeastern North America before the early 1900s, when Black Locust became commonly planted in these areas.

In our first year of the Butterfly Blitz, I wrote a blog post about Silver Spotted Skippers. Even though they are a large and somewhat showy butterfly, there were only six iNaturalist observations of the Silver Spotted Skipper in the Credit River Watershed before 2019. This made them a good symbol of the relatively low level of butterfly surveying that had taken place in the watershed.

I am happy to report that the 2019 Butterfly Blitz added 25 additional Silver Spotted Skipper observations, and the 2020 Blitz another 52. These observations are well distributed throughout the watershed (see map here). I think that we are well on track to adding many more Silver Spotted Skipper points to that map by the end of the 5th year of the Butterfly Blitz! The same is true for many other butterfly species in our watershed, for which we are getting a better understanding of where they can be found each year.

This is all thanks to you, our wonderful Butterfly Blitz participants! Keep butterflying – we love seeing your observations and knowing that they are contributing such useful data.

Strategies for Invasive Plants Management from NPT

Native Plant Trust (http://www.nativeplanttrust.org/) offered a seminar today (06/16/21), called Strategies for Invasive Plant Management. I found it enlightening and very interesting. The main takeaways that I wanted to share were from the discussion of mechanical plant management, and replacement with native species. But first, here’s a little info about the seminar.

NPT's Synopsis:
“Invasive plants continue to be one of the main threats to the ecological integrity of natural communities and to populations of rare plants. Native Plant Trust’s Ecological Programs Coordinator, Bud Sechler, examines different strategies for combating invasive plants, drawing on invasive plant management experiences with Native Plant Trust, the Massachusetts Invasive Plant Advisory Group, and the Sudbury-Assabet-Concord Watershed Cooperative Invasive Species Management Area.”

Other courses:
They are offering another course in the same vein in mid-September (see link below) and I am really looking forward to attending more of their seminars. http://www.nativeplanttrust.org/events/invasive-plants-identification-documentation-and-control/

Mechanical Removal:
Mechanical removal includes cutting, and digging up plants by the roots. Many invasive species thrive on disturbed soil, and regenerate readily from small root fragments, so be sure to read about your target before launching an attack. Bud recommended using a spading fork rather than a shovel, so as to avoid breaking the roots and leaving bits behind. For cases where you cannot/should not disturb the soil, cutting invasive plants to prevent flowering/seeding can be effective, but this approach requires maintenance.

Replacement with Native Species:
One way to prevent an invasive plant from regenerating in disturbed soil after removal is to plant native species at the site. The list here https://grownativemass.org/Great-Resources/nurseries-seed gives many sources for native plants. If you want to avoid replacing non-natives with cultivars, these should be great sources. Bud also recommended transplanting local species from nearby to the site. Of course you should be very careful of digging up native species, even for the best of causes. Please get permission/advice from an expert first.

The following list is as many of the environment-specific recommendations for hardy, competitive native replacements as I could write down before the slide switched.

Dry, Upland Woods: maple-leaf viburnum, lowbush blueberry, early azalea, dwarf serviceberry, black huckleberry
Moist, Upland Woods: witch hazel, upland blueberry
Streamside: northern spicebush, common winterberry, nannyberry, coastal sweet-pepperbush
Wetland or Swamp: common buttonbush, speckled alder
Open, Sunny, Dry Areas: New Jersey tea, sweet fern, smooth serviceberry, staghorn sumac
Dry Pollinator Meadow: butterfly milkweed, yellow wild indigo, wild bergamot
Moist Pollinator Meadow: spotted joe-pie weed, cardinal flower
Low Shrub Cover: small bayberry, lowbush blueberry, serviceberry, lingonberry/cowberry

Pollinator Week Challenge


Pollinators perform a valuable ecosystem service and are critical to the success of plants after fires! Some pollinators may be more abundant after fire, following the flush of flowers. Pollinators may be flies, bees, butterflies, wasps, beetles, moths, ants, birds, bats, mice...wind and water don’t count for our challenge though.

This weekend is the start of Pollinator Week and the Fire Followers Project will be celebrating this year with our new pollinator challenge! This time, we will be partnering up with the Xerces Society to bring you an exclusive challenge and reward in addition to our very own!

Challenge Details:
Starting June 19-27, we encourage you all to go out and make as many observations as possible in any of the burn sites. Keep a close eye out for flowers being pollinated along your hike! This week, there will be an opportunity for 3 individuals to win a Fire Followers Pin! Here are the categories:

Most pollinator species observed:
Most observations of pollinators:
Most identifications of pollinators:

Xerces Society
Bumble Bee Watch Project
Like stated before, this year we are partnering with the Xerces Society to bring you more opportunities to be involved in community science efforts and for a chance to win some amazing prizes. In addition to our own challenges done on iNaturalist, we will also be utilizing the California Bumble Bee Atlas, which is one of several Xerces community science projects using the Bumble Bee Watch platform.

The California Bumble Bee Atlas is a community science project of the Xerces Society for Invertebrate Conservation, the California Department of Fish and Wildlife, and other partners. California is home to half of the bumblebee species found in North America, but there has never been a systematic survey of these important pollinators of wild and crop plants. At least 1/4 of the state's native bumble bees are now imperiled, and some have been proposed for state or federal Endangered Species Act listing. Building on the success of the Pacific Northwest Bumble Bee Atlas, over the next three years, project volunteers will collect data on the distribution and diversity of California's bumble bees, creating a baseline dataset to which future conditions can be compared. Because bumble bees can usually be identified by experts from photos, volunteers will submit photos and other data to project coordinators, but will not have to destructively sample the bees themselves. The California Bumble Bee Atlas will give volunteers the opportunity to learn about the ecology and habitat needs of some of the state's native bees, and they will also make real contributions to scientific efforts to monitor and conserve these important insects. You can join the project by registering at https://www.cabumblebeeatlas.org/.

Challenge Details and Prizes
The Xerces Society will be awarding the top 5 contributors of bumble bee observations to the Bumble Bee Watch site. Winners will have Choices from these 3 books! (shown above!)
1)Attracting Native Pollinators https://www.xerces.org/publications/books/attracting-native-pollinators
2)Plants to save the Bees https://xerces.org/publications/books/100-plants-feed-bees
3)100 Plants to save the Monarchs https://gifts.xerces.org/products/100-plants-to-feed-the-monarch

As a reminder, in addition to uploading your observations on iNaturalist, be sure to also submit your observations to the Bumble Bee Watch Platform in order to have an opportunity to win! Be sure to head over and sign up to upload your Bumble Bee observations!

Submitting a Sighting in the Bumble Bee Watch Project is easy!
1)Head over to https://www.bumblebeewatch.org/ and create an account
2)Take a photo (Just like you would do for iNaturalist)
3)Identify your species
4)Sighting will be verified by an expert

Instructions on signing up and uploading your observations are here:
https://www.bumblebeewatch.org/

Please feel free to contact me at jesparza@cnps.org for any questions! I look forward to seeing all of your observations!

Zoo Ridge 12-13 June 2021

Someone cancelled last minute and I landed an unexpected invite to join some fellow hikers to a weekend to Zoo Ridge, southern Cederberg.

Super excited as I have never been there before, I made sure I took 2 powerbanks to ensure I have adequate power for making the most of the trip in terms of observations in this unexplored area.

Being keen on photographing fynbos, I felt a bit disappointed as we drove into the farm in the dark on Friday evening. The veld looked more Karoo-like, scattered with small shrubs, but several restio bushes along the gravel road gave me hope.. We arrived and set up camp and the magnificence of the milky way overhead settled any further reservations I may have had, the starlight was so dense and bright, one struggled to distinguish even the southern cross and scorpio.

Early the next morning in bright sunshine, we headed out towards the 'ridge' and soon soon along the way I met my first ever protea glabra (didnt know her name at that moment), but bowed to her beauty and brilliance, she looked like the cederberg-version of protea nitida, similar flower shape, but with soft warm brownish outer 'bracts', is that what they are called? and a more stringy growth pattern, to be expected in this harsh environment.

The morning unfolded amongst strange rock formations and clambering rock faces, I was surprised at the large 'dung' middens of supposedly klipspringer, dassie and rock hare of whom you saw no over signs, scat of caracal, holes of aardvark, two owls flying off, plentitude of miniscule oxalis scattered close to the ground, fountainreeds!, and even some kind of buchu,, lichens on the rocks everywhere ..it felt like sacriledge to even step on them lightly .. and then, as some of the group were exploring some rock crevaces below, in a tiny rock cleavage right next to my feet... the find of the weekend! it looked like an ancient bonsai plant, the 'trunk' crooked and about 5cm long, stalks with spiky short green leaves, harsh, but with large plump soft creamy-white tubular flowers that melted me in the instant I set eyes upon them. I later discovered it is aptly called bedrock heath, erica maximilliani, but in that moment, names did not matter. I excitedly snapped and snapped away to record this miracle and beauty from every angle, and low and behold found at least another 3 or 4 more of them all in similar locations, rooting seemingly directly into rock!

The weekend flowed from one observation to the next, I fell behind the group and had to run along several times to catch up (there are no paths) so as to not get lost, but caught many snapshots of this seemingly forgotten treasure of a place, the veld abounding with signs of life everywhere, the ancient rocks and formations and arches mindblowing and providing the perfect backdrop to an ecosystem that seems to have existed even before time itself.

Taking effective images of Schoenus species

Similar to grasses and other grass-like plants, Schoenus species can be very difficult to identify even with the use of a high powered microscope. Photos, such as those posted on iNaturalist, can be useful in identification, but they generally have to show some key characters with fairly high resolution.

Generally, photos should focus on the following characters:

1) HABITAT: Is the environment where the plant growing wet, dry, flat, on a mountain slope, for example? If possible, a photo showing the general environment with neighbouring plants can be a helpful clue.


In the left photo, the species is from a wet draw, which is a clue that it might be from the former Epischoenus group or Schoenus ligulatus. The species to the right is from a drier location in a mountainous habitat.


2) GROWTH FORM: How tall is the plant? How big is the tuft? Most Schoenus species will form clumps, but some species (e.g., Schoenus gracillimus) can be spreading.


The plant in the left image is somewhat spreading, whereas the growth form in the plant to the right is tufted. The tufted growth-form is very common in this group.


3) INFLORESCENCES: These are the flowering heads. A CLOSE-UP image of at least one flowering head is imperative for identification. The individual spikelets making-up the flowering head will ideally be in a mature form, but not too old.

The overall form, length and width of the inflorescence is important when making an identification, as well as characters such as whether the inflorescence is sticky or if it has auricles (membranaceous 'flaps'). If one looks carefully at the image to the far left, you will notice that it is sticky (characteristic of some species in the Schoenus compar - Schoenus pictus group). The image to the far right has a membranaceous flap at the base of each individual flowering head. This character can be hard to see since these flaps are rather transparent.


4) SPIKELETS: These are the composite of flowers that are the individual parts of the flowering heads. They can be very difficult to focus in on with your camera, so sometimes it is best to pick them off of the flowering heads and take a picture of them on a piece of paper. It is even better if you have a small ruler to function as a scale.


A high quality view of the spikelets is often very important in making an identification. Important characters include length, width, and shape. Spikelets have glumes which are the bracts associated with the individual flowers. If you zoom into the image on the right, you will see that there are about four to six glumes for each spikelets. Another important character of the glumes is whether they have reddish-purplish spotting, such as the Schoenus bolusii image to the right.

The image of the spikelet on the following Wikipedia page illustrates spikelets with glumes in more detail: https://en.wikipedia.org/wiki/Schoenus_arenicola


5) BASES OF FLOWERING STEMS: This is not the nicest image to take, because it often involves removing a little bit of the plant from the ground. The process can be a little dirty and won't result in the prettiest picture.

The left and middle images were taken from plants with membranaceous bases, whereas the bases of the flowering stems are more firm in the species in the right.


6) NUTLETS: Photos of the fruits of Schoenus species are useful in identification, especially for species such as Schoenus exilis; however, mature nutlets are not always present on a plant. If you can isolate a nutlet in the field to get an image - GREAT! It will be appreciated.


I thank Doug Euston-Brown and Nicky van Berkel for supplying images for this blog post.


ADDITIONAL RESOURCES

Over the last two years, I have been making a series of Wikipedia and Wikispecies pages which includes images of key characters. This process is ongoing, and I am still not able to make some pages because the respective names still haven't been passed through all of the important nomenclature databases. However, several of these pages exist and show some important illustrative images of key characters, such as spikelets, nutlets and close-ups of flowering stems.

Currently, the best way to access these images is by typing the species name into your web browser.


Good-luck with the hunt!

Differences among gazelles in the structure and function of the tail

There has been no standard lexicon by which the tails of ungulates can be compared. Here, I use 'shaft' to mean the flesh-and-bone structure, and 'tassel' to mean the long hairs concentrated distally. In all gazelles, the ventral surface of the tail is dark bare skin. I refer only to adults, and I ignore the use of the tail in shooing insects.

In Gazella, the tail is simple in structure but demonstrative in function. The tassel is bushy and dark, and covers most of the shaft. The tail is proportionately smallest in Gazella gazella and largest in Gazella subgutturosa. It is wagged and raised during walking and trotting, but reaches the fully upright position in flight only in Gazella subgutturosa and Gazella marica. The latter two species are odd also in possessing, on the sides of the base of the shaft, pale fringes of fur which can be piloerected.

In Nanger, the tail is simple and undemonstrative. The tassel is small, and in Nanger dama almost absent.

In Eudorcas, the tail is larger than in Gazella, and equally demonstrative. However, the emphasis is on wagging during nervous, intermittent walking. Once the animal runs the tail tends to be relaxed.

In Antilope, the pelage on the tail tapers in a way subsuming the tassel, which is neither long-haired nor dark. The tail is undemonstrative during locomotion, except in stotting (when it is erected) and in masculine display (when it is 'hypererected' to the degree of being turned upside-down).

Antidorcas and Litocranius have similarly tapering tails ending in similarly dark and small tassels. However, in the former the shaft is whitish (see https://www.istockphoto.com/photo/protective-mom-and-baby-springbok-stare-back-in-the-desert-gm160377111-22791345)
alamy.com/stock-photo-south-africa-mountain-zebra-national-park-springbok-tails-spinning-16434530.html) and the tassel is piloerected while the tail is inert, whereas in the latter the shaft is dark and the tassel is permanently lax (see https://stock.adobe.com/search?k=gerenuk&asset_id=30423210). In neither genus is the tail demonstrative.

In Ammodorcas, the dark tail is more demonstrative than in any other gazelle, because it is dark, extremely long, and erected during flight. However, there are too few photos of this genus to reveal the details.

As far as I know, no gazelle holds its tail erect (as seen in certain species of deer) or wags its tail in stationary alarm. Thomson's gazelle (Eudorcas thomsoni) has a reputation for doing the latter, but videos show that the tail is activated only once a leg moves.

Mississippi Kites are nesting in Maryland!

After years of steadily mounting evidence, we have very clear nesting confirmation this year in Rockville, Montgomery Co., Maryland. (Other nesting locations are likely.) Here's a photo of a Mississippi Kite on its nest in Montgomery Co., Maryland courtesy of Tim Frye via iNaturalist. (c) Tim Frye, some rights reserved.

This rare but increasing spring migrant is now expected on favorable raptor migration days late April and May. As it increased as a breeder in the northeastern U.S., it became clear that nesting in Maryland was all but certain. They have a special affinity for hunting dragonflies on the wing and are certainly benefiting regionally from the periodical cicada (Magicicada) emergence.

And let's always remember why abundant insect biomass and biodiversity are important to MIKIs (great banding code) and other birds. Their incredible migrations require huge amounts of fuel and summer food supplies to fly from distant wintering grounds. That's why MBP is kicking off more targeted data collection efforts such as the Turkey Point Bird Count and new Summer Nocturnal Insect Surveys. We need a LOT more data to ensure we can protect the world's biodiversity and great natural spectacles.

And where will these Mississippi Kites go after breeding in Rockville or Oklahoma or Georgia? Why, all the way to central South America! Switch this eBird map filter from year-round to June-July and then to December-February to see reports focused around Paraguay and northern Argentina.

Amazing! Neotropical migrants aren't OUR birds that "fly south for the winter." They're tropical birds that visit for a bountiful breeding season, and that bounty is, for most species, insects! Let's ensure these epic migrations remain worth their while! Birds need biodiversity.

Thankfully, all insect eaters are pretty much covered every 17 years thanks to our region's Magicicada emergence and overwhelming protein extravaganza.

Here's to everyone having any easy summer after this last year!

¡Comenzamos a ser Ciudadanos Científicos!

Para ser un ciudadano científico es necesario bajarse la app y darse de alta en la plataforma inaturalist, con esta aplicación desde el móvil o desde nuestro PC en casa, subiremos las observaciones de seres vivos siempre que salgamos al campo. Considera usar iNaturalist como tu cuadernos de campo.

Aquí tenéis un videotutorial sobre cómo darse de alta y comenzar a registrar observaciones:
https://www.youtube.com/watch?v=Y9TOdcnp-V0

Algunos consejos:

  1. Uníos al proyecto de vuestra localidad. Desde la app lo podéis encontrar en Opciones -> Proyectos -> buscar -> escribe Biomaratón otoño (vuastra localidad) -> Unirme
  2. Desactivar la opción de sincronización automática de las observaciones en la app, subidlas cuando tengáis wifi. Aun teniendo plan de datos, hay sitios con mala cobertura móvil. Pero en todo caso no te agobies, disfruta de tu paseo, haz las fotos y ya las subirás cuando llegues a casa. A veces es más rápido hacer las fotos con la cámara del móvil, fuera de la app, y luego compartirlas con como si las enviarais, pero en vez de elegir la opción compartir por whatsapp o correo,…eliges compartir por iNaturalist. La app permite grabar y subir sonidos(canto de aves).

La passione

La passione nasce dalla terra stessa tra le mani infangate dei più piccoli, viaggia lungo maniche sporche di erba e arriva diritta al cuore…”

Итоги проекта "Долгожданная весна"

Проект "Долгожданная весна" стартовал накануне Всемирного дня леса 21 марта и завершился 30 мая. Участниками проекта стали команды юных натуралистов из 5 человек (5 школьников или 4 школьника с руководителем или консультантом). Все участники должны являться зарегистрированными пользователями iNaturalist.

Всего зарегистрировались 14 команд из 10 субъектов Российской Федерации (Ивановская, Тульская, Ярославская, Московская, Курганская, Пензенская, Челябинская, Орловская, Ленинградская, Кемеровская области).

Текущие результаты фиксировались зонтичным проектом https://www.inaturalist.org/projects/dolgozhdannaya-vesna-zontik .

39 наблюдателей из 11 команд загрузили на платформу iNaturalist свои фото- и аудиофайлы. Всего участниками проекта встречено, сфотографировано, загружено и определено 11668 наблюдений (в зачёт шли наблюдения исследовательского уровня) 977 видов живых организмов.

Лидером по количеству наблюдений стала команда "Космос" МАУДО "ЦДЮТур "Космос" города Челябинска" под руководством Ярослава Магазова - 5592 наблюдения 443 видов. При этом более половины наблюдений (3694) было сделано руководителем команды, активным пользователем iNaturalist.

В номинации "Максимальное число видов" лидером стала команда "Умки-2" из МБОУ "Центр образования № 38 г. Тулы" (руководитель - Светлана Борисовна Ястребова) - 544 вида и 2121 загруженное наблюдение исследовательского уровня.

Хочется отметить команду "Бересклет" МОУ СОШ №26 Орехово-Зуева Московской области, занявшую 4-е место и в зачёте наблюдений, и в зачёте видов. Но ребята стали лучшими среди команд, состоящих исключительно из школьников.

Самым удачливым натуралистом, встретившим в рамках проекта максимальное число видов, стал Евгений Бениханов из тульской команды "Умки-2" - 422 вида.

Учитывая напряжённый ход проекта, когда ежедневно менялись лидеры и итоговые результаты, первые 4 команды получат дипломы победителей с указанием достижений по номинациям, остальные команды, перешагнувшие минимальный порог - дипломы участников.

Огромное всем спасибо! Это был интересный проект и интересный опыт, мы обязательно повторим его, учтя все ошибки и замечания, поступившие во время мероприятия. И будем рады вашим откликам.

Hakea Invasions in Portugal and South Africa

General Scope of Project:

There has been much debate on iNaturalist about the identity of the Hakeas/Needlebushes invading Portugal and perhaps even South Africa. Historically we thought it was the Sillky Needlebush Hakea sericea, but there is increasing evidence that the Portuguese invader is Bushy Needlewood Hakea decurrens subsp. physocarpa.

This project hopes to involve Citizen Scientists to help sort out the issue. Briefly:

  • What is the true identity of the Hakea sericea-like species in South Africa and Portugal?
  • Is there only 1 invasive species in each country, or might there be some localized introductions of close relatives?

We require help from anyone interested. We need the following from as many populations as possible:
Please take observations from populations with the following photos (bold most important):

  1. : flowerhead with open flowers - with mm rule (clearly showing flowerhead stalk, flower stalk, and pollen presenter, hairs on pollen presenter). Note the pollen presenter (pistil, style, gynoeceum) - the length from the base to the tip is the most important measurement of all. Close-up if possible to show hairs on the pistil.
  2. : leaf on stem - with mm rule (clearly showing leaf stalk, and angle of leaves to stem, full leaf length, and leaf tip (mucro))
  3. : close up of new/young branchlet to show the hairs
  4. : follicle top view - with mm rule (showing the sculpturing on the surface, the size and shape of the horns)
  5. : opened fruit if present showing the colors of the inside
  6. : seeds if present (close-up)
  7. : habit of plant (showing any resprouting tendencies)
The flowerhead photo has the most useful diagnostic characters (unfortunately, these involve size, which is why we need the rulers in the pictures), so please put this as the first picture on your observation. The order of the other pictures is not important. Please feel free to record other information (for example, in South Africa you might include:
  1. which biocontrols did you see? [Gummosis, Follicle Weevil, Follicle Moth, Girdling Weevil, other]. If you can photograph any of these - please do so as a separate observation, and include a link to the plant observation [use the "Interactions (s Afr)" project].
  2. What proportion of plants are dying from Gummosis Fungus?
  3. How old is the veld?
  4. Habitat.)

Merely make observations: this project will collect the results and display them. You are welcome to do this for any Hakea species, but this project will focus mainly on these two species, plus any others in the Hakea sericea (Needlebush) group invasive in the Cape and Portugal (and New Zealand).
Other members of the group (predominantly from the eastern states of Australia. are
. Hakea actites,
. H. constablei,
. H. decurrens (P),
. H. gibbosa (C, NZ)
. H. kippistiana,
. H. leucoptera,
. H. lissosperma,
. H. macraeana,
. H. macrorrhyncha,
. H. ochroptera,
. H. sericea (C, NZ, P?)
. H. tephrosperma,
.

同定と知識

最近、以前に撮影した写真を見ていると今ならわかるものが見つかる。
残念ながら同定のポイントを外して撮影していることも多い。

わかるところは同定のお手伝いをしようと思うんだけど、知識が中途半端だから思い込みで同定しがち。

undescribed and reassigned species in Cape Peninsula sea slugs (branchs?)

some stuff:
so.. Trinchesia speciosa is a species complex...
I believe Jessica Toms has a paper coming out -- not sure what to do about that name-wise?
note that Placida dendritica is a non-local species, ours is Placida capensis
seems like Jorunna tomentosa is a Euro species and ours is a cf. tomentosa for now
they say Philinopsis speciosa but Terry says morphology differs and ours is Philinopsis capensis
very confusing geographic stuff going on with Cadlina sp-a and sp-b but let's rather wait for that
the Tritonia -- two species so far as I know -- the purple soft coral nudi (which may be Marionia sp.)
and the brush nudi (which may also be Marionia)
the whip fan nudi was Tritonia odhneri is now Duvaucelia sp. not odhneri which is a North Atlantic species (I think)
Thecacera pennigera is Thecacera sp.
Aplysia parvula is a sp.
Kaloplocamus ramosus is a sp.
Terry says our Elysia is rubropunctata but it's not mentioned on WORMS so.. dunno what to do about that
our Crimora lutea is actually a sp.
Anteaeolidiella indica is in fact saldhanensis
Pleurobranchaea albiguttatus is in fact nigropunctatus...
Doriopsilla miniata is in fact areolata
we don't have Rostanga pulchra -- it's elandsia
https://www.inaturalist.org/observations/67656614 is an observation of Flabellina sp1 in Gosliner 1987
and https://www.inaturalist.org/observations/14981368 is an observation of Flabellina sp2 in Gosliner 1987
(I added both to undescribed species and taxa)
also, all the Discodoris sp in the project need to be reassigned to Paradoris

June 1 trip etc.

Forgot to post this from the first week of June:

Months before I started the master’s program at CSULB and before I had a permit to collect in the national forest, I started looking for off-trail routes into Ladd Canyon, first by hiking up the Silverado Trail to Main Divide on the east, then by biking up Black Star and along Main Divide from the west. It’s an absolute joy to get into places few others have and see the grandest old trees and lilies upon lilies. But the bushwhacking is also the bane of my research. It just takes time, and I worry that I’m less observant when I’m tired out or simply looking for my way. This is why I tried to get a good jump on route finding before the collecting season began.

From the beginning, I have been concerned about the time it takes to get to the lower canyon from public access points. I got permission from CNF to backpack a couple of nights in the canyon for this reason. So it was a huge help when CNPS’s Ron Vanderhoff put me in touch with Scott Breeden and through him Susan and Anthony Mack, who have allowed me to access the lower canyon from Ladd Canyon Road. I can’t thank them all enough! On May 10 and 11, I backpacked with Mike McDermott and was able to explore halfway up West Fork. There’s a beautiful little falls up there, and a plant or two (perhaps most worth mentioning is a population of Monardella hypoleuca, 1B.3, also found in the main canyon). Having already backpacked down the main fork of the canyon and up East Fork, I felt like I had covered most of the area. All of which brings us to recent goings-on in Ladd Canyon.

When spring finally came, there was a bit of easy collecting in easy-to-get-to places. Perhaps there could have been a bit more, but yeah, it’s been pretty dry. In the last couple of weeks, I’ve poked around ravines and ridges along Main Divide, as well as the lower canyon riparian area. I was also thinking about how to get to the middle section of West Fork that I still hadn’t seen. Down and back from Main Divide would be a long day. I explored a ravine halfway down the south ridge of Pleasants Peak (the Smashmouth use trail following SCE power lines is on this ridge) hoping for a short route, but I was stopped by the largest dry fall I’ve seen in Ladd Canyon, probably 40 to 50 feet -- not sure because safety first! I didn’t get too close. This week, after looking at topos and satellite images, I decided I would head down West Fork from Main Divide and try going up a different ravine to Smashmouth. If it worked, I’d have a good day, and if it didn’t, I’d have a good, long day retracing my steps.

The middle section was beautiful, with some huge big-leaf maples and white alders, as well as some year-round pools with four big groups of horsetails, Equisetum telmateia. My route up to the ridgetop worked, but I can’t say that I’m eager to repeat it. It involved a scree slope (there’s been Phacelia imbricata on every scree slope I’ve scrambled -- love those shapely leaves), and some stubborn chamise and manzanita. I collected some Collinsia heterophylla -- not a rarity in the Santa Anas but a plant I hadn’t seen yet. It reminded me again to pray for rain next year. The going got easier when I reached the large stand of knobcone pines near the top. It was a steep 1,000 feet and getting late, so I had a little lie-down and the last of my water. My last observation of the day involved those pines. Vogl (1973) said the knobcones in the area were all associated with serpentine soil, but I had doubted that because it didn’t look to be the case along the Smashmouth trail. Climbing up through these trees, though, I came upon yet another outcrop of friable white rock with rusty red streaks that I think is serpentine-associated silica-carbonate. I still have to confirm that, but I feel guilty for ever doubting Vogl. Asking questions, though, that’s just science, right?

Soon to come: exploring the east fork of East Fork and revisiting summer bloomers in the mint and aster families.

First post: An intro to the project

Ladd Canyon is an intriguing area of the Santa Ana Mountains to study. There are no official trails into the canyon. The old Ladd Canyon Spring Trail is no longer maintained, and the so-called Smashmouth on Pleasants Peak’s south ridge is an unofficial route following SCE power lines installed in the early 2000s. Most past botanizing has been along Main Divide, although there are some old records from the short Ladd Canyon Spring Trail in upper East Fork. Reason enough to get into the canyon to see what is there! But there is more to consider here. The area at the north of Ladd around Pleasants Peak has the only serpentine soil in the Santa Ana Mountains, and serpentine is an important source of endemic species in California. It has also been suggested that moist marine air is funneled by the local topography up through Ladd Canyon, increasing moisture levels. The knobcone pine stands near Pleasants Peak are said to be associated with the serpentine soil and to rely on fog drip from the wet marine air. Their needles really do collect an impressive amount of water in morning fog. Finally, the canyon has been largely untouched by fire since the Green River Fire in 1948.

These abiotic factors could make a difference in the plant community in this part of the mountains. This project is an effort to document all the vascular plant species in Ladd Canyon, and many of the iNat observations here are associated with voucher specimens that will be preserved at the herbarium at California State University, Long Beach.

Wasps of Dough Flat

A couple weekends ago when we had a cool day I made my first trip up to the Dough Flat parking lot in the Sespe wilderness. I didn't see any condors, but spent a lot of time happily photographing all the insects on the flowers that morning. I sat for about a half hour each at two very active sites.

One was a cluster of buckwheat flowers that were heavily visited by some yellow-and-black wasps - looking at them, I thought Philanthus (beewolves), but I couldn't swear they weren't Bembicini (sand wasps). The flowers were also visited by a cuckoo wasp, the firsts I've seen visiting flowers (they get in the house occasionally in spring, but I've never seen one outside before).

Presently 2 others have identified the yellow-and-black wasp as Philanthus, and one identifier has suggested Hedychrum for the cuckoo wasp.

The taxon info for Hedychrum says that this genus is typically a brood parasite of Philanthinae. So that's cool!

The map put these two observations on opposite sides of the trail but it's GPS error, I didn't move between taking the two photos and they're of the same buckwheat shrub.

Common Eastern Bumble Bee

I am extremely afraid of bees and wasps, so I was not very happy to see a Common Eastern Bumble Bee on May 26th. I was scared to get too close so I observed the bee from a safe distance and relied on zooming to get good pictures of it. The bee was busy with the flower that it had landed on, thankfully. The scientific name for this bee is Bombus impatiens. It is a member of Kingdom Animalia (Animals), Phylum Arthropoda (Arthropods), Subphylum Hexapoda (Hexapods), Class Insecta (Insects), Subclass Pterygota (Winged and Once Winged Insects), Order Hymenoptera (Ants, Bees, Wasps, and Sawflies), Suborder Apocrita (Narrow-waisted Wasps, Ants, and Bees), Infraorder Aculeata (Ants, Bees, and Stinging Wasps), Superfamily Apoidea (Bees and Apoid Wasps), Epifamily Anthophilia (Bees), Family Apidae (Honey Bees, Bumble Bees, and Allies), Subfamily Apinae (Apine Bees), Tribe Bombini, Genus Bombus (Bumble Bees) and Subgenus Pyrobombus. One of my greatest fears is getting stung by a bee, so I hope I do not encounter more in the future.

Faint-spotted Angle

On the night of May 31st, a moth flew into my home after the door was left open by accident. I noticed that it was attracted to light and preferred to hang around the light bulbs in the house. It also flew really fast and it was hard to catch. The scientific name for this moth is Digrammia ocellinata. The Faint-spotted Angle is a member of Kingdom Animalia (Animals), Phylum Arthropoda (Arthropods), Subphylum Hexapoda (Hexapods), Class Insecta (Insects), Subclass Pterygota (Winged and Once Winged Insects), Order Lepidoptera (Butterflies and Moths), Superfamily Geometroidea (Geometrid and Swallowtail Moths), Family Geometridae (Geometer Moths), Subfamily Ennominae, Tribe Macariini (Angle Moths and Allies) and Genus Digrammia. I thought it was fascinating that the moth blended in with my carpet so well.

Cope's Gray Tree Frog

On May 29th, I stepped out onto the back porch to get fresh air and look at the morning scenery. On the arm of the bench on the porch, I noticed a little frog. I was fascinated by how well it blended in with the wood of the bench, I almost didn't see it there. The scientific name for a Cope's Gray Tree Frog is Hyla chrysoscelis. It is a member of Kingdom Animalia (Animals), Phylum Chordata (Chordates), Subphylum Vertebrata (Vertebrates), CLass Amphibia (Amphibians), Order Anura (Frogs and Toads), Family Hylidae (Tree Frogs and Allies), Subfamily Hylinae (Hyline Tree Frogs), Genus Hyla (Holarctic Treefrogs), and Complex Hyla versicolor (Gray Tree Grog Complex). I found the tree frog adorable.

Crane Fly

On the night of June 1, 2021, I was spooked when I encountered a crane fly in my bathroom. It was my first time seeing one and it looked like a giant mosquito to me. I made sure to take a quick picture of it to upload to iNaturalist before removing it from my home. The scientific name for the crane fly I saw is Tipula furca. It is a member of Kingdom Animalia (Animals), Phylum Arthropoda (Arthropods), Subphylum Hexapoda (Hexapods), Class Insecta (Insects), Subclass Pterygota (Winged and Once Winged Insects), Order Diptera (Flies), Suborder Nematocera (Nematoceran Flies), Infraorder Tipulomorpha (Crane Flies), Superfamily Tipuloidea (Typical Crane Flies), Family Tipulidae (Large Crane Flies), Subfamily Tipulinae, Genus Tipula, and Subgenus Yamatotipula. I honestly hope I never encounter one up close again because the experience was very frightening for me.
