National What Week?

N aturenet has every fact the good environmentalist needs or wants... Calenderand this is the one page you've been asking for for years. An incomplete guide to the national and international days and dates in the wildlife and living environment calendar, which might stimulate some idea for events you can run yourself in support.. A few are included which, whilst not strictly environmental, might be good themes for events. We don't list events that are location-based, as the idea is that these are events that others can join in with.

Something missing? You know the details? Tell us here.

We include a few days which seem to have reached the end of their natural lives - but there's always room to revive them so the most recent information is still given. Where only the last year's date is shown it may be that the next date is not announced yet - or we haven't noticed it. Some of the dates only get set quite late in the year, so check the link in the right-hand column if there is one. It might be helpful - but some of these websites don't make it easy for you!
