The Occoquan Region Monitoring Project

This program was initiated in 1991 at Occoquan National Wildlife Refuge just south of Washington DC by Jim Waggener of the Northern Virginia Audubon Society. In 1996, two more areas were added (Occoquan Regional Park and Meadowoods Management Area). Finally, 2001, a route at Metz Wetlands. This project is focused on protected lands in this limited area. Future sites may include the Featherstone National Wildlife Refuge just south of Occoquan NWR. The surveys were primarily focused on helping to direct restoration and conservation efforts. Although not a standard "Pollard" design, it has 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. There are two types of surveys conducted approximately monthly at each of four survey routes. One collects data on multiple species, including butterflies and the other only counts butterflies and dragonflies (and these are conducted from April through October).

Protocol

Protocol Type: Restricted search
Data Type(s): Abundance
Data Availability: Contact program director
Survey Focus: Adults
Incidental Data Collected: Weather, Host / nectar plants, Other (see Protocol Notes)
Visit Frequency: Monthly
Effort Tracking: The number of observers and the time spent on each route is recorded. Route length never varies.
Protocol Notes: 5-10 observers walk one of four routes weekly (but on two days using two different protocols), so each route is visited approximately monthly (although 2 times, once for each protocol). In one protocol, all wildlife is observed (including butterflies). Those surveys are done monthly throughout the year. The second protocol only records information on butterflies and dragonflies. These surveys are done from April through October.
