Trolling for Leeches

Sometimes you’ve got to roll up your sleeves – or pants leg – to get the job done, as I was doing to identify leeches in the Concord woods during Walden Biodiversity Day, a 24-hour bio-blitz to inventory all species that can be seen with the naked eye in Concord, Carlisle and Lincoln Massachusetts.
Peter Alden - trolling for leches in Walden Woods

The Worcester News-Telegram wrote an excellent article here – The crushing truth: Some ants smell funny – and there’s coverage in The Boston Globe here – A day for seeing all living things, great and small that will give you a taste of the day.

Many thanks to everyone who worked so hard to make Walden Biodiversity Day a success!
