The Cascade Butterfly Project was launched in 2011 to monitor butterfly populations in the North Cascades and Mt. Ranier National Parks. There are two types of monitoring protocols that are used. Nine permanent transects were established between the two parks. These 1 km transects are visited several times per season and use pollard protocols. Volunteers are also encouraged to report incidental sightings through BAMONA's sightings database.
