DNR employees aboard the Alpena Fisheries Research Station boat Chinook measure fish caught in gillnets for the annual Saginaw Bay fish community survey. Each fish is identified, counted and measured for total length. Target species, where more information is required, also will be weighed and examined to determine sex, maturity, stomach contents and more. Scales or spines are collected to allow the age of the fish to be determined later. The survey requires that most of these fish are sacrificed, but biologists learn an enormous amount about the health of the fish populations and often the same specimens are provided to others for more study; any fish remaining of any consumption value are donated to food pantries.
DNR employee tagging a walleye (Sander vitreus) with an Internal/PIT tag. These tags are an implanted tag which contains a series of numbers and letters that can be obtained by passing a "PIT Tag reader" over the implanted tag. The tagging program helps biologists to determine movement and seasonal distribution of the species.
DNR employees release an elk with its new radio collar as part of a capture operation for the DNR's four-year research project to evaluate the movement patterns, population characteristics and health of elk near Atlanta in Montmorency County. A helicopter was used to drive the elk into open areas, where an individual animal could be captured in a net fired from a special net gun. Once ensnared, the elk was subdued by field researchers, and then fitted with radio collars, provided a field checkup for basic health signs and given an antibiotic shot. Scientists also took hair, blood and fecal samples. The operation captured 20 bulls and 20 cows, achieving its capture goal.
DNR employees pull a tranquilized black bear (Ursus americanus) out of her den, preparing to attach a radio collar. The radio collar will help DNR biologists track the bear and allow for checkups to aid in their research of the species in Michigan.
A crewmember of the DNR's Survey Vessel Steelhead lowers a digital sensor into Lake Michigan. The crew conducts an annual hydroacoustic (sonar) and mid-water trawl survey of alewives and other prey fishes (like the mottled sculpin) in Lake Michigan to get a snapshot of current conditions. Once the survey work is completed, estimates of total prey fish abundance are generated by managers and are used to balance predator-prey dynamics. Fisheries managers then adjust salmon stocking rates to keep alewife abundance in check with lake productivity levels.
DNR employees measure a fish caught as part of a population survey on one of Michigan's rivers to collect data for the Fisheries Division's Status and Trends Program (STP). The STP surveys fish communities and habitats in lakes and streams that are representative of the broad range of waters found in Michigan.

A group of DNR employees and volunteers hold onto Canada geese while their information is recorded and the are prepared to be banded. The DNR is responsible for banding hundreds of ducks and geese each year, with quotas set by the U.S. Fish and Wildlife Service according to local conditions. The banding process is performed by DNR employees and trained volunteers. Once the age and sex are recorded, a metal, pre-numbered, federal ID band is placed loosely around the goose's leg and gently pushed closed with a pair of pliers. Waterfowl hunters across the United States and Canada are asked to report any harvested birds with federal identification leg bands. Doing so assists waterfowl managers when it comes to setting future hunting seasons and bag limits.

A group of DNR employees, boy scouts and volunteers gather mallard ducks that have been netted for banding near East Lansing. Every year, the DNR attempts to band ducks as part of a national survey, which focuses on mallards, wood ducks and black ducks. The mallards are affixed with aluminum bands; each with its own unique number, plus a phone number and address. Hunters who later harvest a banded duck are encouraged to report the bird's band number to the telephone number or address printed on the band. The goal of this program is to engage hunters in the collection of data about ducks and to help set quotas and establish hunting seasons that coincide with migration patterns.

DNR employees prepare a young peregrine falcon (Falco peregrinus) to be banded. Young peregrine chicks are banded so they can be identified later should they turn up in another state or are found injured. The peregrine falcon population was decimated by the use of the pesticide DDT in the 1950s and 1960s. The DNR has worked with other agencies to successfully restore peregrines in Michigan, and the banding program helps in these efforts.

This study is designed to better determine population abundance, growth and survival, and harvest and fishing pressure.

A Wildlife Services employee from the U.S. Department of Agriculture oils double-crested cormorant eggs in a nest to prevent young from hatching as part of a population control measure on the Les Cheneaux Islands in Lake Huron. The booming cormorant population has been pointed to as a reason behind the decline of certain sport fisheries. The DNR works with the U.S. Fish and Wildlife Service in recommending sites for population control.
DNR employees release a white-tailed deer after it has been tagged with an ear tag.
Adult and youth collect an American Beaver (Castor canadensis) from a trap. The DNR has established specific trapping seasons when furbearers may be taken. Wildlife biologists recognize trapping as an important wildlife management tool and regulate and scientifically monitor trapping to ensure that the most humane methods are used and that the population is never endangered.
