Effects of local habitat characteristics and landscape context on grassland butterfly diversity

Article Abstract:

The butterfly community diversity is studied in four types of grassland habitats surrounded by varying amounts of urban development near Boulder, Colorado to understand the importance of local and regional habitat characteristics. The importance of maintaining high-quality grassland habitat to protect native butterfly diversity is emphasized.
