Ash trees showing the damage of emerald ash borer larvae. In the spring, ash trees will not leaf out in portions of the canopy due to the feeding of emerald ash borer larvae. This feeding leads to canopy dieback and eventually death.
Forest Management fire officers manage a prescribed fire. These prescribed fires are intentionally ignited under a strict set of weather and site conditions to accomplish a specific resource management or ecological objective.
DNR employee clears buckthorn bushes while another (not in shot) applies herbicide to prevent future growth. Both common and glossy buckthorn are considered invasive non-native shrubs. Their rapid growth and prolific seed production make these plants aggressive invaders that can form dense thickets which shade and displace native understory plants, shrubs, and tree seedlings.
A DNR forest health specialist checks under the bark of an ash tree for signs of emeral ash borer.
A flowing river after having its dam removed. Virtually all of Michigan's large rivers had dams constructed on them. Most of these dams were built between 1900 and 1955, with construction activity reaching its peak in 1914. Many of these dams have deteriorated because of age, erosion, poor maintenance, flood damage and poor designs, and many of them no longer serve any useful purpose. Removal eliminates the expenses of future maintenance and repairs, improves public safety and provides several ecological benefits

Forest Management fire officers set and observe a prescribed fire. These prescribed fires are intentionally ignited under a strict set of weather and site conditions to accomplish a specific resource management or ecological objective.
A stand of ash trees that have been damaged by the emerald ash borer, an invasive beetle. In the spring, ash trees will not leaf out in portions of the canopy due to the feeding of emerald ash borer larvae. This feeding leads to canopy dieback and eventually death.
DNR employee cuts buckthorn and applies herbicide to prevent future growth. Both common and glossy buckthorn are considered invasive non-native shrubs. Their rapid growth and prolific seed production make these plants aggressive invaders that can form dense thickets which shade and displace native understory plants, shrubs, and tree seedlings.
Removal of a dam on a Michigan river. Virtually all of Michigan's large rivers had dams constructed on them. Most of these dams were built between 1900 and 1955, with construction activity reaching its peak in 1914. Many of these dams have deteriorated because of age, erosion, poor maintenance, flood damage and poor designs, and many of them no longer serve any useful purpose.

DNR employee applies herbicide (the green on the cut portions in the foreground) to newly cut buckthorn shrubs to prevent future growth. Both common and glossy buckthorn are considered invasive non-native shrubs. Their rapid growth and prolific seed production make these plants aggressive invaders that can form dense thickets which shade and displace native understory plants, shrubs, and tree seedlings.

A bag of garlic mustard (non-native invasive plant) pulled by volunteers. Pulling garlic mustard is part of the DNR's early detection and rapid response initiative. Garlic mustard impacts forest regeneration by shading-out young tree saplings.
A pair of mating emerald ash borer beetles. The emerald ash borer is an invasive species in Michigan and detrimental to ash trees.
A group of volunteers pulls garlic mustard (non-native invasive plant). Garlic mustard removal operations such as this are part of the DNR's early detection and rapid response initiative. Garlic mustard impacts forest regeneration by shading-out young tree saplings.
Report on observations of and possible control measures for gulls and terns, whose population increased as a result of recent dredging operations.
Since ceasing extensive planting of autumn olive, the Michigan Department of Natural Resources has sought means to control the spread of autumn olive into open habitats. We conducted an evaluation of the effectiveness of 2 herbicides in combination with a prescribed burn to kill autumn olive at the Rose Lake Wildlife Research Area in East Lansing, Michigan. Sixteen clumps of autumn olive shrubs were treated with Garlon 3A, 16 clumps were treated with Glyphomax Plus, and 16 Control clumps were not treated with herbicide. After treatment, the field was burned in early September 2004. In September 2005, we evaluated the percent live canopy on the 48 autumn olive clumps. All 16 of the Garlon 3A treated clumps were dead (no live canopy). Three of the 16 Glyphomax Plus treated clumps were dead. All of the control clumps were alive. The percent live canopy was also used to evaluate impacts of the herbicide treatments on clumps. Treatment with Glyphomax Plus resulted in significantly more clumps in the lowest percent live categories than the Control. Results of this evaluation indicate that treatment with Garlon 3A in combination with a prescribed burn is an effective way to kill autumn olive while Glyphomax Plus followed by a prescribed burn significantly reduces the vitality of autumn olive plants, but does not lead to death.
Report on the Norway Project, which lies in the south half of Dickinson County, covering general character of the land, whildlife and cultural features.
Memorandum of suggestions on how to proceed with wildlife and soil conservation after ditch-cleaning operations in Ohio.
Evaluation of Early Detection Rapid Response program and use of the Incident Command System in responding to two new reports of the invasive species European frog-bit received during the summer of 2013.
Habitat Conservation Plan developed to facilitate the conservation of the Oak Savanna Ecosystem, Karner blue butterfly and other associated species of concern on non-federal land in Michigan. The plan outlines activities that will be conducted to maintain the early-successional habitat conditions necessary to support savanna species and communities.
