Maintenance Level Guidelines
in spring or fall, depending on slope and soil conditions. This will help keep the brush from forming thickets. Seeding is done on a limited basis using a low grow seed mix of mainly native plants. The mix will consist of some non-native, short lived annuals like Plains Coreopsis, Bachelor Buttons for color. Prairie development will be done on a project basis – scheduling burns, prairie grasses and wild flower seeding in accordance with land-use plans. See Appendix B – Natural Area Management Guide – Upland Prairie Plant list. 16.2 Woodland Management Pruning and tree removal will only take place in areas where the dead or broken branch of a tree will pose a safety risk to nearby property or park patrons using a path or trail. Pathways and trails may be present thru the woodlands and will consist of grass or wood chips. See Appendix B – Natural Area Management Guide – Woodland Plant list. 16.3 Brush and Invasive Species Removal Brush removal is a key to natural area restoration. Fire does not eradicate larger trees and shrubs and these will need to be removed manually and the stumps treated with a herbicide. Some of the species are as follows: European Buckthorn, Asian Honeysuckle, Sandbar Willow, Gray Dogwood and Multi-Floral Rose. Another exotic plant that degrades natural areas is garlic-mustard. Herbicide applications and manual cutting are needed for eradication. Other invasive species such as Teasel, Reed Canary grass, Purple Loosestrife and others are discussed in Appendix B - Natural Area Management Guide. 16.4 Wildlife Management With proper restoration to natural areas comes an increase of wildlife species which is usually not a problem. One species that has become a problem is the Canadian Goose. Canadian Geese are a federally protected migratory bird, and the control measures are limited. The primary cause of high geese population is the common practice of planting pastures of bluegrass next to bodies of open water. This area next to the shoreline needs to be allowed to grow taller to reduce the visual lines of sight of the geese and increase their perception of the danger of predators. Another control measure is the federally permitted process of egg and nest depredation. This is a very effective way to keep the population from growing too rapidly.
