The Innoko National Wildlife Refuge conducts a wide range of science based research and monitoring programs. Each of these programs produce in-house reports on a yearly basis. As publications are developed they will be made available on this site. Below are brief descriptions of current programs.


The Innoko Refuge staff conduct a moose census in the late winter of even-numbered years. The refuge is divided into a north and south half, the census efforts alternate between the two halves. Unlike other refuges, moose are counted using a helicopter that follows predetermined straight lines (line transects methods). This technique was pioneered here at Innoko Refuge. The reason behind development of this technique was to try to find a method of counting moose that was both efficient, safe, and scientifically valid.
In the spring following each moose census, crews take to the field after the ice breaks up on the rivers, but before leaves come out, to measure the amount of available winter forage moose consumed. This gives biologists another measure of the status of the moose population and helps to explain the numbers collected during the census effort.

In cooperation with the Boreal Partners in Flight program five breeding bird surveys are conducted on the refuge. An additional survey is conducted on behalf of the U.S. Air Force at the Tatalina Radar Station near McGrath.

In cooperation with the Alaska Regional office, Innoko Refuge staffare working on the documentation of frog abnormalities on the refuge. Refuge crews go out in mid-July in search of frog metamorphs in various ponds.

A project to map the substrates of the principal rivers on the refuge is nearing completion. The information gained will assist fishery biologists in the future as they assess the status and size of various fish resources on the refuge.
