U of M landscape ecologists work for a healthier environment by studying and promoting wetland restoration, lakescaping, and rainwater gardens.

U of M horticultural scientists continue to research ways to restore and preserve Minnesota's water quality through strategic plantings that restore wetlands, preserve lakeshore, and curb runoff through rainwater gardens. Although they do not develop plants, researchers analyze the most beneficial plants for various conditions and provide the public with information on plant selection.

In wetland demonstration sites, researchers are investigating whether short-lived perennials can be used to suppress reed canary grass that invades damaged wetlands, and whether adding nutrients increases the likelihood of weedy plant invasion.

Lakescaping--natural landscaping along lakeshores--enhances the quality of lakes by restoring fish and wildlife habitat and protecting water quality by reducing runoff. The vegetation protects the land from erosion and reduces yard maintenance.

Rainwater gardens of hardy plants sited in low-lying areas trap and absorb runoff from parking lots, streets, and roofs. Gardens filter storm water close to where it falls and prevent additional runoff and pollution.

The U of M flower and grass breeding programs lead research to prevent the creation of invasive crops prior to their release in the market. Possible solutions include releasing cultivars that are completely sterile (no seed or pollen production), that cannot flower (foliage plants), or that cannot establish outside of cultivation.
