Next up was Chris Zimmerman, talking about "Invasive plant species inventory and assessment of the Beaverkill Forest Matrix Block in the Catskill Mountains in southeast New York." This was an extensive mapping project looking at the distribution of a dozen different invasive plants. An analysis of road classes in the surveyed region found that they were a good predictor of whether invasive plants would be present or not, with transects by trails having relatively few invaders and true roads having more. Another interesting finding was that land with a home density of even just one house per km had more invasive species richness than land with no houses at all.
I noticed that the "Acknowledgements" slide at the end of the talk listed an Anonymous Donor...note to self: acquire anonymous donor!
