Ruffed Grouse Drumming Counts on all Ranger Districts

OBJECTIVE/PURPOSE OF PROJECT:

The ruffed grouse is Minnesota's most popular game bird and an important part of the State's biological diversity. It occurs throughout the forested regions of the state, including all of the Superior NF. The purpose of surveys of grouse populations in Minnesota is to monitor grouse population cycles, changes in the densities of grouse over time. This provides information that helps project how well the birds will respond to management and helps develop a better understanding of how populations are impacted by changes in their environment.

METHODS OR TECHNIQUES USED:

Established roadside routes consist of 10 stops approximately one mile apart. Routes are surveyed once annually just after sunrise between April 10th and May 20th. Attempts are made to conduct surveys on days near the peak of drumming activity that have little wind and no precipitation. At each stop an observer listens for 4 minutes and records the number of ruffed grouse drums (not necessarily the number of individual grouse) he or she hears. Acres accomplished based on an assumption that each stop surveys 20 acres. Forestwide routes are run by partners in the MN DNR, Superior National Forest, Vermilion Community College, and other citizen volunteers. This includes routes on the East Zone Districts (8), Kawishiwi (4); Laurentian (6); LaCroix (2).

REALIZED/EXPECTED RESULTS:

Contribute to total survey for stae of Minnesota. Full 2010 Report can be found at the MN DNR website (link shown below). In 2010 observers from 15 cooperating organizations, including the Superior NF, surveyed 125 routes. There was a significant decrease from 2009 counts in the northeast (31%) and state wide (27%).
