Located in northeastern Schoolcraft County, the refuge is removed from major population centers. The three nearest major communities are all over 80 miles away. The 95,455 acre refuge was established in 1935 in what is locally known as the Great Manistique Swamp. Habitats range from marshes and open water areas to hardwoods, spruce and pine forests. There are 21 major, managed impoundments with 7,000 surface acres. The 25,150 acre Seney Wilderness Area, characterized by string bog topography, is located in the northwest corner of the refuge. Also administered from the Seney National Wildlife Refuge are the Huron Islands National Wildlife Refuge and Wilderness Area, eight small islands located off the south shore of Lake Superior, and the Harbor Island National Wildlife Refuge in Lake Huron. Total acreage is 842 for these two satellite stations. Typical Summer Scene on the Refuge (JP) TABLE OF CONTENTS Page INTRODUCTION i A. HIGHLIGHTS 01 B. CLIMATIC CONDITIONS 02 C. LAND ACQUISITION 1.

Researchers from Ohio Cooperative Wildlife Research Unit conducted a soft release project with refuge sandhill cranes (see D-5). Many personnel changes occurred in 1988. The Project leader position and the refuge biologist position were changed (see E-l). High fire danger occurred in the summer resulting in station fire fighters responding to ten project fires, two of which occurred on the refuge (see F-9). Field inspections were conducted for Farmers Home Administration properties in Michigan. Assistance was also given in wetland restorations (see F-14). The Seney Natural History Association was formed and received a grant from the National Fish and Wildlife Foundation (see H-18). This year marked the first season of entrance fee collections (see H-20). Renovation construction was completed on both the office and one phase of the shop (see 1-2). •-< 2 B. CLIMATIC CONDITIONS Weather records which include precipitation and temperature for 1988 are from the National Oceanic and Atmospheric Administration cooperative weather station located at the refuge office. The refuge has maintained an official station since January 21, 1939. Refuge personnel record rainfall, snowfall, snow depth, and temperature daily including weekends and holidays during the summer months. The Secretary transmits this weather data to the Admini stration's computers via telephone on their ROSA encoder. The months of April, May, June and July were the driest on record. However, the refuge received 7.29 inches of rain in August, well over the normal 3.11 inches, which began to raise the below normal annual precipitation level. The year ended with a slightly more than average annual precipitation total of 36.7 inches. The temperature readings for the year showed higher than normal temperatures with the highest reading on July 8 of 99 degrees. It is unusual for the Upper Peninsula to experience these high summer temperatures because of the affects of the surrounding Great Lakes. The 1988 snowfall of 86.1 inches was well below the average 125 inches of snowfall. 3 • f Table#! 1988 WEATHER STATISTICS Precipitation Max. Min. Total Normal Snowfall Temp. Temp.

LAND ACQUISITION Other An exchange of property between the refuge and the Michigan Department of Natural Resources was proposed in 1986 to straighten irregular boundaries on the south end of the refuge. No final agreement has been made regarding the land exchange with the State of Michigan. The Land Protection Review Board approved the exchange in December of 1986. It is anticipated that the exchange will be finalized during 1989 . 5 D. PLANNING 2. Management Plan Management Plan Part I and II were revised during the year. Objective levels were adjusted for some categories to provide more realistic goals. A significant change was the lowering of the objective of Canada goose production from 1080 to 450. This was because of the increase in the giant Canada goose population throughout Michigan's Upper Peninsula. 5. Research and Investigations SNY NR-84-31510-1 and Ohio Cooperative Fish and Wildlife Research Unit (14-16-0009-1539). Nesting, Productivity and Movement of Greater Sandhill Cranes of the Upper Peninsula of Michigan, Dr. Richard Urbanek Nineteen eggs were collected on Seney National Wildlife Refuge via helicopter May 19-22 and hatched in an incubator May 20- 29. Chicks were reared in 1.36- x 0.91-m compartments that opened to 0.91- x 2.42-m runs. Each compartment contained a crane brood mount with a speaker, from which tape-recorded brood calls were played. Chicks were divided into four socialization groups and were exercised for about 1 hr each day, following a person in a puppet costume. Two chicks died from accidents and one died from an unknown cause. Health problems were minimal, and no serious leg/toe problems developed. The 16 surviving chicks were observed in sustained flight at ages of 67-81 days. The planned forced association experiments were not done because of poor weather conditions, construction delays, and severe time constraints. Chicks were released in the free association pen in late August. The 1.85-ha pen, an irregular, open-topped, 8-sided polygon, was built on an area of mudflat and shallow marsh. The fence extended 2.4 m above ground and 0.3 m below; an electrified wire was positioned 0.3 m below the top of the fence. A costumed dummy was placed in the pen so the chicks would remain there without brailing. Wild sandhill cranes began coming into the pen on August 28. Chicks were individually color-banded and equipped with solar/Ni-Cad radio transmitters the first week of September. Eight chicks departed from the Upper Peninsula on September 25-28 and migrated along the normal route used by wild cranes to central Wisconsin. Eight chicks that did not depart were transported to the latter area and released on October 23.
