The Kandiyohi Index Area is located in the West-Central part of Minnesota, and has had 79 to 103 lakes surveyed per year between 1994 and 2002. Statistical analysis is ongoing, and has been completed through 2001.
- Loon abundance in the Kandiyohi Index Area ranged from 0.5 - 0.8 adult loons per 100 acres of lake between 1994-2001 (Fig. 1).
- There are no statistically significant changes in occupancy within the six index areas. Occupancy (likelihood of seeing a loon on a lake) was calculated as 28% - 37% in the Kandiyohi Index Area (Fig. 2), the lowest amongst the Index areas.
- Reproductive success was calculated as 0.26 - 0.90 juveniles per 2 adult loons in the Kandiyohi Index Area (Fig. 3), with some of the highest rates amongst the six Index Areas.
- During the study period, the Kandiyohi and Otter Tail index areas were the only Index Areas to exhibit statistically significant increases in goose abundance. Canada Geese ranged from 0 - 13.7 adult geese per 100 acres of lake in the Kandiyohi Index Area between 1994-2001 (Fig. 4).

We extend our heartfelt thanks to the hundreds of volunteer observers who continue to make the MLMP a success. Without your persistence and hard work, the DNR would be without a means of reporting on the health of our state bird. We and Minnesota's loons appreciate your commitment!
We acknowledge the assistance of Dr. Douglas Hawkins, University of Minnesota, for statistical analysis, and Eric Hanson for the initial design and implementation of the MLMP.
