space and time, making the specific causes and effects of change difficult to track. UW-Madison botany professor Don Waller and his research group are studying ecological changes in Wisconsin over time by comparing modern data with a rare and valuable historical resource a detailed dataset of plant communities in the state compiled by John Curtis in the 1950s.
Four presentations at the ESA meeting will describe some of the group's approaches to understanding what factors drive ecological change and how such changes are affecting Wisconsin's environment today. Their studies show that forest habitat fragmentation, invasive plant species, and deer have each profoundly impacted Wisconsin's forests over the past 50 years. In many areas, native species have declined, invasive plants have gained a foothold, and overall plant diversity has dropped as previously diverse areas become more and more similar. An understanding of the factors underlying ecological change may help guide efforts to identify vulnerable habitats and management strategies to protect the state's natural resources.
