8. Natural Resources 8 Natural Resources
Natural resources - including lakes, rivers, wetlands,prairie, and woodlands - contribute to the
livability and sustainability of our region. These natural areas recharge our aquifers,provide
plant and animal habitat, and reduce air pollution. Stewardship of natural resources and
balancing development with conservation should be an important consideration in your
comprehensive plan.
IiMinimum Requirements:
• Describe your community's goals, intentions, and priorities concerning preservation,
conservation, or restoration of natural resources in your community.
0 Get More Out of Your Plan:
• Prepare a local natural resource inventory that incorporates free-standing local natural resource areas as
well as those that connect with larger corridors.
• Include goals,priorities,and natural resource conservation strategies to protect and enhance natural
resources in your comprehensive plan.
• Adopt and implement ordinances for the conservation and restoration of natural resources within your
community.
• Collaborate with adjacent communities and other partners to identify,plan for,and protect natural resource
areas that cross boundaries.
• Establish and maintain conservation areas for plant and animal habitat management.
NATURAL RESOURCES
• Include goals, priorities and natural resource conservation strategies to protect and enhance
natural resources
• Land use policies should recognize natural areas and open space as long term uses in our
community
Urban Forestry
• Set goals for species diversity on public property. Encourage public education for diversity
goals.
• Invasive species threats. Emerald ash borer is a current threat to Chanhassen trees but others
will be coming. Determine broad response programs and protocols to ensure sustainability of
Chanhassen's urban forest and natural areas.
• Determine goals for street and park tree management, woodland preservation and/or
restoration and forest health protection
Natural areas/Greenways
• Establish and maintain conservation areas for plant and animal habitat management.
• Prepare a natural resource inventory that incorporates free-standing local natural resource
areas as well as those that connect with larger corridors.
Soil
• Establish goals and policies that address soil conservation, such as protecting soils from
compaction during development, reducing erosion on steep slopes and bluffs.
Biological Diversity
• Identify rare species and natural areas as noted by the Minnesota County Biological Survey and
commit to the protection and management.
• Address and commit to pollinator-friendly practices
• Set goals to limit fragmentation of natural areas and maintain green corridors that connect open
space
• Address management of aquatic and terrestrial invasive species
Public Education
• Set goal to promote public education of natural resources

RARE SPECIES AND ANIMAL AGGREGATIONS
Lucations of raw plants, rare animals, and.elected animal aggregations are maintained in the Natural Heritage Information System
The following rare species and animal aggregations(that include rare and common species)haw been found in Carver, Hennepin,
and Scott counties. Mapped locations include both historical records and the results of field surveys conducted by the Minnesota County
Biological Survey in 1996 and 1997 Most rare species are protected under the provisions of the Federal Endangered Species Act or the
Minnesota Endangered Species Statute and associated Rules . An asterisk(')indicates that no recent observation(1970-1997)of that
species has been confirmed. A dagger( #)indicates that the species has been documented in one of the counties but its exact location
is not determinable

Adjust mowing frequency and timing to help pollinators.
• If you have a lawn service or are considering getting one,talk about your desire to
conserve pollinators and protect their habitat.
Management practices influence pollinator activity
• Identify and understand pests and beneficial insects.To identify Minnesota insects visit
www.extension.umn.edu/garden/diagnose/insect/
• Accept some insect damage on plants.
• When using a pesticide,especially an insecticide,choose a product that won't harm bees and still be effective.
Apply when bees are not foraging.Follow the label exactly.The label is the law. (See the information box on
minimizing impacts of pesticides on pollinators and the accompanying insecticide toxicity chart).
• Adopt Integrated Pest Management(IPM)in your garden.IPM uses information about pests to manage pest
damage with the least possible hazard to people,property,and the environment.For more information on IPM in
landscapes and homes visit:www.mda.state.mn.us/news/publications/pestsplants/pestmanagement/ipm/home-ipm-
