Common carp, introduced from eastern Europe over a century ago, are an invasive species in Minnesota that adversely affect water quality and aquatic communities, particularly in shallow lakes and wetlands. While solutions for suppressing common carp reproduction and abundance are emerging, controlling the movement of common carp, and therefore preventing reinfestation, has so far proved difficult.
The University of Minnesota’s Landscape Arboretum is the largest and most diverse horticultural site in Minnesota. It features gardens and natural areas representative of Minnesota and the upper-Midwest that can be explored using several miles of trails. Additionally it conducts fruit and plant breeding research to develop cultivars that have particular desired characteristics, such as cold hardiness or disease resistance. The arboretum has a long-term goal of protecting the entire watershed of which it is a part.
Pollinators play a key role in ecosystem function and in agriculture, including thousands of native plants and more than one hundred U.S. crops that either need or benefit from pollinators. However, pollinators are in dramatic decline in Minnesota and throughout the country. The causes of the decline are not completely understood, but identified factors include loss of nesting sites, fewer flowers, increased disease, and increased pesticide use. Developing an aware, informed citizenry that understands this issue is one key to finding and implementing solutions to counteract these factors.
