Butterfly community monitoring on City of Boulder Open Space and Mountain Parks property: analysis of the changes in species richness and diversity from 2002 to 2016
Butterfly populations are naturally patchy and undergo extinctions and recolonizations. Recent published research indicates that butterfly fauna show a net loss over time in species richness and diversity, when populations are subject to anthropogenic disturbances like development, climate change, and invasion by nonnative plant species. This document reports on an analysis of changes in butterfly community over time at 18 transects, distributed in six habitat types, and sampled in five different years: 2002, 2007, 2008, 2015, and 2016. Species richness and diversity was greatest in earlier years ...
