The Occoquan Regional Monitoring Project is focused on monitoring protected lands at several sites south of Washington DC. Both butterflies and dragonflies are surveyed as part of butterfly/dragonfly surveys that take place April through October. Butterflies are also surveyed as part of year-round general biodiversity surveys. Survey routes are located in the Occoquan Bay National Wildlife Refuge, Occoquan Regional Park, Meadowoods Management Area, and Metz Wetlands. The surveys are primarily focused on helping to direct restoration and conservation efforts. Although not a standard "Pollard" design, surveys have many of the key features of that monitoring protocol - survey routes are established and the same routes are walked each time at a consistent pace. In addition to surveys, North American Butterfly Association (NABA) Seasonal Counts are conducted at four sites.
PollardBase is an online system for managing butterfly monitoring programs.
