Just found this website - http://www.conkertreescience.org.uk/
They are trying to do various surveys, and have iPhone and Android apps to accompany the survey to make it easy.
They have another project ongoing;
http://planttracker.naturelocator.org/
Which is to try and track non native plants - again they have apps, and the more data they can collect the better.
What is in your wood?
