is conducted regularly at Arrowwood NWR to determine animal and plant baseline
data, to monitor trends in populations and in changes in the natural communities,
and to measure management effectiveness. Here are the primary ongoing
each year, formal field surveys are conducted by Refuge staff and volunteers.
Waterfowl breeding population surveys (Four Square Mile Survey) are
conducted twice annually in May and June as part of the Prairie Pothole
breeding ground survey organized by the USFWS Habitat and Population Evaluation
Team (HAPET) group based in Bismarck, ND. The National Mid-Winter waterfowl survey is
conducted annually in January, with additional waterfowl surveys every week in
October and November. Nest surveys are conducted each summer to determine if
piping plovers are utilizing the refuge for nesting. In addition, Bald
Eagle surveys are conducted each January.
Nest searching to monitor waterfowl nest success is also conducted
annually, and several other national wildlife monitoring surveys are completed
including; mourning dove call counts, breeding bird surveys, and Sandhill crane
In order to assess
current conditions and have a baseline of quality vegetation status, a vegetation map of Arrowwood was identified as
a necessity. Conducted in 2011-13, development of the vegetation map and
associated report was a multi-step process, involving study of aerial
photographs, several months of ground-truthing of vegetation types, and data
analysis. Data can be lumped into broader categories as seen in the first map or if more detail is needed, the mapping project was done to allow a fine scale analysis as shown in the second map.
