I started a traditional project for our U3A Fynbos Rambles. Only 3 of us are active iNatters.

Stats sorted by the month observed as we work back adding our obs. We are over 500 species already.

For a fresh challenge I found a list of our endemic flora - 158 species.

Article by @botaneek (I don't recognise the second author from iNat?)
The endemic flora of the Cape Peninsula, South Africa - N.A. Helme, T.H. Trinder-Smith - South African Journal of Botany - 2006. https://www.sciencedirect.com/science/article/pii/S025462990500030X

Since our moderately fit group walks around and along, rather than up our mountains - we will not find 'everything' on that list. But it will be interesting to retrieve what we have seen, and find what we could still see.
