I am a volunteer and member of the FOTH (Friends of Tygerberg Hills) CREW group. We have been on weekly outings to various sites in our area and occasionally further afield since 2007. The data thus collected is sent to SANBI as a record and to update the Threatened Species Programme.
Update:
I am no longer active in the CREW group but am still interested in Natural History with a strong emphasis on Botany. There are always new and exciting things to discover. Life is wonderful!
