Last September, my wife and i started volunteering at the New York Botanical Garden (NYBG). We agreed to participate in a national study of tree development as Citizen Scientists. Since last September we have been going to the garden once a week to record the changes in certain designated trees. This data is submitted to the national phrenology network to be studied and collated with other data collected by others here and throughout the US.
Scientists use this data to see what changes are taking place in the normal development of the various tree species. This is reflective of global warming.
Committing to two years of this was a wise idea, otherwise we would have never gone every single week. It is also very enjoyable. There is an easy way for anyone to get involved by contacting the national phrenology network.
