Endocrine-disrupting contaminants such as environmental estrogens have been found and studied in large lakes and streams and shown to exist at concentrations that have adverse effects on wildlife. However, very little is known about the sources and effects of environmental estrogens in small, shallow lakes. Preliminary data suggests that these compounds are present in shallow lakes and have an effect on the survival and reproduction of wildlife. Researchers at the University of St.
Moose, one of Minnesota's prized wildlife species, are dying at much higher rates in Minnesota than elsewhere in North America. Recently observed increases in mortality rates amongst some moose in northeastern Minnesota have led to concern that the population there may be entering a decline like that seen in the northwestern part of the state, where moose populations fell from over 4,000 to fewer than 100 in less than 20 years. Additionally the specific causes of increased mortality amongst individual moose remain under investigation.
With only 1% of Minnesota’s native prairie remaining, many prairie plant and animal species have dramatically declined. Of the 12 butterfly species native to Minnesota prairies, two species, the Poweshiek skipperling and the Dakota skipper, have already largely disappeared from the state and are proposed for listing under the U.S. Endangered Species Act despite being historically among the most common prairie butterflies and having their historic ranges concentrated in Minnesota.

Lebanon Regional Park, implement elements of the Visitor Center Interpretive Concept Plan to engage, educate, inform and encourage stewardship and preservation.
Agricultural drainage is very prevalent practice in Dodge County and there is a need to implement practices to that will better manage flow and pollutant loads that are being contributed to nearby surface waters. This project involves the installation of a woodchip bioreactor on a tile-drained agricultural field, which will feature improvements in design, and monitoring scope, as compared to a previous bioreactor constructed in Dodge County in 2007.
Pasture and hayland account for 62% of the agricultural land use in Clearwater County. In 2012, it was the 12th largest producer of beef cattle in Minnesota. In a county where 22% of pasture/hayland acres are within 300 feet of riparian areas, management practices need to be introduced that enhance rather than restrict the farm operations that use these zones for their livelihood. Clearwater County's Silver Creek and Ruffy Brook are currently listed as impaired by fecal coliform.
To upgrade the HVAC system and insulation at The Charles A. Weyerhaeuser Memorial Museum in order to both meet museum and historic preservation standards.
This program will develop a centralized, integrated approach to managing existing data systems and incorporating new information needs into the integrated enterprise information system of data.
Space and water heating and cooling consume 48% of all energy used in an average U.S. residence, and usually that energy is supplied by natural gas or fossil-fuel derived electricity. Geothermal heat pumps can reduce energy requirements for heating and cooling by up to 75%. However, traditional geothermal heat pumps are expensive and their performance is difficult to predict before installation.
In 2009 and 2010, more than 565 Minnesota teachers benefitted from professional developmentworkshops led by the Minnesota Historical Society. These innovative training opportunities included:
To hire qualified technicians to install a heating, ventilating, and air conditioning (HVAC) system in the Ames-Florida House, now part of the Rockford Area Historical Society's museum facilities, listed in the National Register of Historic Places.
