Managers from the Three Rivers Park District natural resources program met with NIACS staff to use the adaptation workbook in December 2017. The considerations will be incorporated into future planning efforts.

Project Area

The Three Rivers Park District manages regional parks in the western Twin Cities, Minnesota. The Three Rivers Park District Natural Resources Management department is responsible for restoring and protecting natural resources—such as native plant communities, wildlife diversity and water quality—in Three Rivers' park reserves and regional parks. The Natural Resources section includes Forestry Management, Horticulture and Landscape Management, Water Resources Management, and Wildlife Management.

The Three Rivers policy for the planning and management of natural resources allows no more than 20 percent of a park reserve to be developed for active use and requires that at least 80 percent of the park reserve be restored to and retained in a natural state.

In keeping with this policy, Three Rivers is actively involved in the preservation and restoration of wildlife and plant species.

Management Goals

Managers were asked to articulate the primary goals for the natural resources program as a whole and for specific programs within the larger program.

District-wide:
  • Restore, preserve, protect and protect native ecosystems
  • Decrease invasive species
Forestry:
  • Manage forests to ensure that the majority of species are native
  • Make forests resilient to change
  • Restore native forest communities (big woods, oak-hickory)
Wildlife:
  • Increase patch sizes
  • Increase connectivity across habitats
  • Provide prairie habitat
  • Conserve native species
Water:
  • Promote healthy, diverse aquatic ecosystems
  • Meet state water quality standards for recreation benefit

Climate Change Impacts

For this project, the most important anticipated climate change impacts include:
Increase in invasive plant species in both terrestrial and aquatic areas.
Increase in pests and pathogens to both plants (e.g., bark beetles, bur oak blight) and humans (ticks, mosquitoes).
Drought stress, in particular to nursery trees.
Warmer winters, impacting wildlife, seed germination, and nutrient loading.

Challenges and Opportunities

Climate change will present challenges and opportunities for accomplishing the management objectives of this project, including:

Challenges

effects on the ability to manage invasive species (for example, hot temperatures can decrease effectiveness of chemical treatments)
meeting water quality standards with higher temperatures and more intense storms
changes in windows for prescribed burning
stress to nursery trees
more snow-making needed for winter recreation opportunities

Opportunities

a potential reduction in cross-country ski trail maintenance due to a shorter season and less snow
dead trees from storms can serve as habitat for wildlife.
potentially fewer winter fish kills

Adaptation Actions

Project participants used the Adaptation Workbook to develop several adaptation actions for this project, including:

Area/Topic
Approach
Tatics
Drought impacts
Supplemental watering, mulching nursery trees
Consider drought-resistant species as replacements for existing/failing plants
Forest pest and disease
Research biocontrol, new practices
Continue oak wilt control
Coordinate with outside organizations for long term strategy
Continue ash removal program and stop planting ash
Toxic algae
install raingardens
Work to develop new BMPs
Invasive species
Anticipate areas prime for invasive species and act quickly
Increase fire intensity and frequency
Consider assisted migration of native species that are adapted to future conditions
Increase overall diversity
Warmer winters
Change mulching practices to protect bare roots and plantings
Manage curly leaf pondweed through more treatments, monitoring potential outbreaks, and increasing native competition
Increase season length in which invasive species are treated

Monitoring

Project participants identified several monitoring items that could help inform future management, including:
Seed viability of newly introduced species
Survival of introduced species
Stratify vegetation surveys on areas where invasive species are removed
Add tree health indicators to vegetation surveys
