A DNR researcher holds a mottled sculpin (Cottus bairdii) caught during a nighttime trawl of Lake Michigan as part of a prey fish survey. The crew of the DNR's Survey Vessel Steelhead 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.
A man nets a child's Chinook Salmon (Oncorhynchus tshawytscha) catch on the St. Joseph north pier on Lake Michigan.
A firefighter dampens the roof of a house in order to prevent it from bursting into flames.
DNR Fisheries Division employees out of the St. Clair Research Station place a lake sturgeon (Acipenser fulvescens) into a holding tank on their research vessel Channel Cat to be measured, examined and then released as part of their Lake St. Clair sturgeon survey.
Aerial view of the Upper Tahquamenon Falls on the Tahquamenon River surrounded by early fall foliage. The root beer color of the falls is caused by high levels of tannins in the river. The falls are more than 200 feet across with a 48 foot drop.
Fisheries Division employees use gill-nets to survey inland lakes for cisco, also known as lake herring. The survey has two purposes - to find out where cisco populations exist and to, potentially, serve as brood stock lakes should the DNR ever decide to re-introduce the creatures into other waterways.
An ice fishing family sets up a a tip-up (device set on the ice above the hole that dangles the bait beneath them; they feature small reels submerged in the water, and get their name from a flag that's bent over and attached to the reel. When a fish takes the bait, the reel turns and releases not only line, but the flag as well, alerting the angler to the fish taking out line).
An instructor helps a woman learn to hold a shotgun as part of a Becoming an Outdoors-Woman (BOW) program. BOW is a national program created to introduce women to traditionally male outdoor activities. In Michigan, DNR's BOW program are offered year round at many locations and range from basic introductory courses to specific outdoor experiences.
A forwarder loads timber as part of the DNR timber harvesting program. The harvested timber is usually offered for sale. Sales are conducted for the purposes of harvesting mature and over mature trees, responding to past or predicted insect and disease outbreaks, salvaging fire-damaged trees, enhancing wildlife habitat and improving health of forest trees. All harvests are designed to enhance growth of the residual trees or to promote full and prompt regeneration.

DNR employees take measurements on a tranquilized black bear (Ursus americanus) before attaching 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.
Millie Hill Bat Viewing Site. The site is actually an old mine entrance that has a protective steel grate that allows bats to enter and leave, but keeps people out of the mine shaft. The Millie Mine is a critical hibernating and breeding location for up to 50,000 bats—one of the largest known concentrations of bats in the Midwest. Big brown and little brown bats from all over the region come here to hibernate during the cold winter months.
Conservation officer recruites lined up and ready to start training. Michigan conservation officers (COs) are fully commissioned as state peace officers, with full power and authority to enforce Michigan's criminal laws. COs are a unique class of law enforcement officer, whose duties include enforcing regulations for outdoor recreational activities such as off-road vehicle (ORV) use, snowmobiling, boating, hunting and fishing. They also are empowered to arrest those who commit felonies, misdemeanors and civil violations of Michigan law.
DNR employees load fertilized fish eggs that have been harvested during a fish take into incubator trays at a state fish hatchery.
An adult and youth show off their wild turkey (Meleagris gallopavo) kill.
Biologist Barb Barton captures Mitchell's Satyr butterflies in Jackson County as part of a mark-and-recapture program. The adult butterflies are caught, marked with a number on a wing with a fine-tipped felt pen and released. The number of times the marked butterflies are recaptured compared to the overall number of specimens captured gives biologists an idea about the size of the population.
Forest in the fall, showcasing beautiful fall foliage, including the bright yellow tamarack larches in the foreground.
DNR employees netting walleye (Sander vitreus) to be tagged and released to determine movement and seasonal distribution of the species.
DNR employees prepare to attach a radio collar to a tranquilized black bear (Ursus americanus). The radio collar will help DNR biologists track the bear and allow for checkups to aid in their research of the species in Michigan.

Adult shows off youth's rabbit kill. Small-game hunting is a popular method to acquaint youth with the joys of hunting.
A piping plover (with leg band) along a shoreline. While the Great Lakes population of piping plovers has rebounded since it was first put on the federal endangered species list, the population remains extremely vulnerable to both natural and human-caused disturbances.
Tunneling by emerald ash borer beetle larvae found just under the bark of an ash.
