It is impossible to compare amphibian populations.
However, we tried to compare the population in 2008 and 2010.
We investigated the number of the same place Rana uenoi in the same place.
I feel right.
Certainly ... The population of Rana uenoi seems to be declining ...
I have done similar research in the same time period in 2016 in San Sali ....

There is not much difference from the result now.
In 2018, about a quarter of the population is likely to be compared to 2008.
In Seosan, Chungnam Province.
