Cats, thanks so much for the link to the
UK phenology site. It's great! I didn't even know what phenology is. For those as ignorant as I, I can tell you that phenology is the study of the times of recurring natural phenomena especially in relation to climate. Such data have been collected in the UK for a few hundres years and in parts of Asia for much longer. This website gives dates of firsts (first blackberry blossom, etc.) in different parts of the UK over a period of years. Everyone is invited to observe and contribute. I'd love to. I keep similar notes for myself. However, I live in the Northeast USA. Does anybody know of any similar organizations closer to my home?

The weather here (suburb of Washington DC) is getting sunnier and warmer, so spring must show some signs soon.
