Students learn about population density within environments and ecosystems. They determine the density of a population and think about why population density and distribution information is useful to engineers for city planning and design as well as for resource allocation.

Biodiversity is a shortened form of the term "biological diversity." The entire spectrum of life forms and the many ecological processes support them. Wisconsin is blessed with abundant biodiversity. Located at the junction of the eastern deciduous forest, northern boreal forest and temperate grasslands, we have a wealth of species and natural communities.

Approximately 1,800 species of native plants and close to 700 species of native vertebrates have been identified in Wisconsin. In addition, there are thousands of species of non-vascular plants and invertebrates. These pages highlight the uncommon and rare species, natural communities, geological features and essential habitat areas throughout Wisconsin.

A key component of wildlife management is understanding the impact that humans have on their surrounding environment. In this activity students will begin to explore the human impacts that their school yard is experiencing from air, soil, and water pollution.

Snapshot Wisconsin is a partnership to monitor wildlife year-round, using a statewide network of trail cameras. Snapshot Wisconsin provides data needed for decision making at the Wisconsin Department of Natural Resources. It is also a unique opportunity for individuals, families, and students to get involved in monitoring the state’s valuable natural resources. This tool is designed to help visualize many aspects of Snapshot Wisconsin data.

Echolocation is the ability to orient by transmitting sound and receiving echoes from objects in the environment. As a result of a Marco-Polo type activity and subsequent lesson, students learn basic concepts of echolocation. They use these concepts to understand how dolphins use echolocation to locate prey, escape predators, navigate their environment, such as avoiding gillnets set by commercial fishing vessels. Students will also learn that dolphin sounds are vibrations created by vocal organs, and that sound is a type of wave or signal that carries energy and information especially in the dolphin's case. Students will learn that a dolphin's sense of hearing is highly enhanced and better than that of human hearing. Students will also be introduced to the concept of by-catch Students will learn what happens to animals caught through by-catch and why.

The Wisconsin Geological and Natural History Survey (WGNHS) has been serving Wisconsin for over 125 years. Part of the Division of Extension at the University of Wisconsin–Madison, WGNHS provides objective scientific information about the geology, mineral resources, and water resources of Wisconsin. We conduct research, map Wisconsin’s geology, and share information through our publications and outreach.

WGNHS has been producing geologic maps, scientific reports, and more for over 125 years. Our publications catalog offers thousands of maps, reports, datasets, and other publications—all of which are available to view and download for free.

The Wisconsin Geological and Natural History Survey (WGNHS) was created by the Wisconsin Legislature in 1897. It is the descendant of earlier state surveys in Wisconsin, which date back to 1854.

WGNHS, part of the Division of Extension at the University of Wisconsin–Madison, is an interdisciplinary organization that conducts natural resources surveys and research to produce information used for decision-making, problem-solving, planning, management, development, and education. Survey is defined to include resource inventory as well as basic and applied research and analysis. WGNHS has no specific regulatory or enforcement responsibilities.

Mission of WGNHS:
Understanding the earth • Charting its history • Sustaining its resources
The Survey conducts earth-science surveys, field studies, and research.

We provide objective scientific information about the geology, water resources, and mineral resources of Wisconsin.

We collect, interpret, disseminate, and archive natural resource information.

We communicate the results of our activities through publications, technical talks, our website, social media, and responses to inquiries from the public.

These activities support informed decision making by government, industry, business, and individual residents of Wisconsin.

Water clarity monitoring is a process in which the volunteer lowers an 8” diameter, black & white disc (“Secchi disc”) into the deepest part of the lake to determine how far down they can see the disc as it is lowered. Water clarity monitoring is done every 10-14 days throughout the open-water season. Water clarity is a quick way to estimate lake health, and it plays an important role in determining the types of plants and animals that a water body can support.

Can also add in collected data for Water Chemistry analysis along with Secchi disc collected data.

This site includes data collection forms for individuals or groups to add their data from their own lake to this dataset.

The National Water Information System (NWIS) Mapper provides access to over 1.5 million sites contained in the USGS National Water Information System (NWIS), including sites where current and historical surface-water, groundwater, springs, and atmospheric data has been collected. Users can search by site type, data type, site number, or place.

NUTSHELL: In the optional Field Enhancement portion of the lesson, the class explores the living and nonliving parts of a forest while on a hike. Students spend individual quiet time observing and drawing parts of a forest. In main portion of the lesson, students match plant species with forest ecosystems and learn that living things are influenced by the nonliving things around them. They create a song or skit to show what they have learned about living and nonliving connections. The students conclude the lesson by creating a mural of different types of Wisconsin forests.
BIG IDEAS
Forests are ecosystems characterized by a dominance of tree cover and they contain a variety of other organisms (e.g., other plants, animals).Forests differ in composition (species within a forest) and structure (layers in a forest). These are both affected by biotic (e.g., animals, plants, humans) and abiotic (e.g., soil moisture, sunlight, climate) factors. 
OBJECTIVES Upon completion of this lesson, students will be able to:
Explain how living things in a forest depend on nonliving things.Recognize that all forests do not contain the same plants and animals.

Students are introduced to the concept of a dam and its potential benefits, which include water supply, electricity generation, flood control, recreation and irrigation. This lesson begins an ongoing classroom scenario in which student engineering teams working for the Splash Engineering firm design dams for a fictitious client, Thirsty County.

Wisconsin’s climate is typically continental with some modification by Lakes Michigan and Superior. The cold, snowy winters favor a variety of winter sports, and the warm summers appeal to thousands of vacationers each year. About two-thirds of the annual precipitation falls during the growing season (freeze-free period). It is normally adequate for vegetation, although drought is occasionally reported. This climate is most favorable for dairy farming; the primary crops are corn, small grains, hay, and vegetables. The rapid succession of storms moving from west to east or southwest to northeast account for the stimulating climate.

Wisconsin's 15,000 lakes. The DNR partners with the University of Wisconsin - Extension and citizens around the state to help protect and maintain these amazing natural resources while providing some of the best recreational opportunities in the nation. More than 600 lake organizations and thousands of volunteers play a leadership role in the stewardship of Wisconsin's lakes.

Find a Lake, Lake Water Quality Data, Lake Maps, Plants and Aquatic invasive Insects - are all linked to this site.

Volunteers, DNR staff, county staff and others collect water clarity, temperature and dissolved oxygen, as well as other water quality data, on lakes across Wisconsin. Around 1,000 volunteers are currently active, and the network has been going strong since 1986. Water clarity is measured with a black and white disk called a "Secchi Disk".

Satellite images are used to retrieve water clarity data for lakes across the state. This effort began in 1999 when the University of Wisconsin-Madison Environmental Remote Sensing Center (ERSC) developed a model for the retrieval of water clarity data from satellite images and Citizen Lake Monitoring Network volunteers provided on-the-ground Secchi data to calibrate this model for each satellite image. Water clarity data was retrieved for over 8,000 lakes statewide between 1999 and 2001. The DNR continues to analyze data in this way today in its remote sensing program.

Data includes Clean Water Act, Monitoring Projects, Healthy Watersheds Assessments, Targeted Watershed Assessments, Wastewater Evaluation, Watershed Planning, County Land and Water Plans, Nine Key Element Plans and more. All datasets from specialized themes are available from this main, general set of layers.

The Wisconsin Environmental Mesonet (WiscoNet) is a growing network of weather and soil monitoring stations across Wisconsin, designed to provide high quality data at high spatial and temporal resolutions. There are currently 14 Wisconet stations with plans to expand to around 90 by 2026. Each Wisconet station provides more than one dozen measurements every 5 minutes.

The stations measure temperature, dew point, wind, rain, soil moisture and temperature, and more.

You can view data through an interactive map or a list of stations.

The Wisconsin Wetland Inventory (WWI) regulatory maps show graphic representations of the type, size and location of wetlands in Wisconsin. These maps have been prepared from the analysis of high altitude imagery in conjunction with soil surveys, topographic maps, previous wetland inventories and field work. The Wisconsin Department of Natural Resources (DNR) manages the WWI.

The U.S. Fish and Wildlife Service (USFWS) began producing non-regulatory, polygonal, geospatial wetland maps for the United States via their National Wetlands Inventory (NWI) in the mid-1970s. While DNR does provide WWI data to USFWS, there can be a significant lag before those updates appear in the NWI.

STATEWIDE: Digital wetlands data are available from the Wisconsin DNR for the state. Alternatively, wetlands are available for free viewing as a layer in the DNR Surface Water Data Viewer.

App: Wisconsin DNR Surface Water Data Viewer

NATIONAL: The NWI is slightly more detailed than WWI since NWI also maps deep water systems including lakes, streams and rivers. The Wisconsin DNR provides their WWI data to the U.S. Fish and Wildlife service for integration into the NWI, but users should be cautioned that Wisconsin updates to NWI can reportedly take months, and in some cases years. Users requiring Wisconsin wetlands data are strongly encouraged to start with the Wisconsin Wetland Inventory.

The Champion Tree Program recognizes and celebrates the state’s largest trees. The Wisconsin Department of Natural Resources began documenting these trees in 1941 with the help of the community. People around the state discovered these trees in the Northwoods, in neighbors’ yards and along city streets. The program has endured as a result of people such as yourself. We invite you to join us in honoring and preserving Wisconsin’s natural resources heritage.
