ABSTRACT: Since the late 1980s, the Illinois Butterfly Monitoring Network has collected butterfly population data on a variety of natural and semi-natural areas. Data collection sites range from high-quality ecosystem remnants, to degraded open lands, to ecosystem reconstructions and urban parks. This long-term data set allows comparison of the effectiveness of these various land types in supporting populations of butterflies. Changes in butterfly diversity and abundance over time, have been observed. Certain observed changes to species composition may correlate with a variety of anthropogenic changes, including climate change.
