*Cattle turn out date is the day they arrive on the pasture. The actual day they arrive at the Mardon skipper sites maybe a few days to 2 weeks later.

1) Search for new sites within the known range of the Mardon skipper. Searches for new sites have thus far been opportunistic of road and trail systems (figures 2-4). It is likely that Pinegrass Ridge was once a large colony. As the forest has regenerated, there are likely many more sites that can be found using current aerial photos. The distribution of the Conrad population should also be mapped. 2) Monitor existing known populations to determine trends in peak numbers and flight periods. 2008 was the first year populations were tracked over time in a few locations. This effort should be continued. 3) Develop and implement a protocol to characterize known sites and neighboring sites that are unoccupied. Gather detailed vegetation and physical data of these sites. 4) Continue monitoring cattle/elk exclosures. Vegetation utilization measurements should be conducted in the same area as counts. We theorize that as vegetation becomes taller and denser inside exclosures, Mardon use will decline.
