Final Yearlist to end of December 2025
stands at 164 species.
A good total in what by recent standards could be considered a quiet year with only 1 new addition to the reserve list, a Hoopoe seen by a lucky few on the 3rd October.

Poinsettias are popular plants often used at this time of year to decorate and brighten up our indoor spaces, so here's an illustration of such a bright flower to brighten up your feeds on this December Sunday morning, curtesy of our 19thC Collection.

Apparently this lichen @northcavewet.bsky.social was wearing 'sunscreen' today. Xanthoria parietina, produces a chemical (parietin) that along with giving it a yellow colouration provides it with UV protection (perhaps a bit optimistic in Yorkshire ... in December 😆) Elsewhere: goldcrests.
