Floras change over time in response to numerous variables, including land use changes, species introductions, climate change, and other factors. This New England Botanical Society talk at 7 pm on February 7 will examine and attempt to explain changes in frequencies of two groups of plants in southern New England: orchids and northern species (i.e., those near the southern end of their range). It will include a discussion of different data sources and their limitations and the challenges of dealing with potentially confounding factors. Speaker Dr. Robert Bertin is Professor Emeritus of Biology at the College of the Holy Cross in Worcester. The talk will be live and on Zoom.
