Community Pollinator Survey, Friends of Greenview
As of June 8, We've added a genus-level network and table summarizing data for Greenview/Pioneer Woods. What does it all mean? In the next month, after reviewing the data across all sites and plants, we will put together an analysis. There will be a lot to say.
