ing/planting Methods Implementation information to include: What is the implementation sequence How will seed/plants be installed for each planting zone Planting rates How will mulch be applied ing/planting Methods Wetland species Broadcast seed. Most species require light to germinate and seeds are very small. They cannot be buried. Many species have seed that floats Upland species May be drilled or broadcast. Generally, forbs should be broadcast and grasses drilled or broadcast (1/4 inch deep) Fall installation is stratified naturally over winter and will germinate in spring Spring installation Many species may not germinate until the following year Mid-summer installation - is worst time to seed ing/planting Methods 0.5 cm of sediment will reduce 90 percent of wetland seed emergence * Should mulch wetland seeding zones Should mulch adjacent steep slopes Pay attention to water level control Many small seeds need light to germinate The smaller the seed, the greater the impact of sediment ing/planting Methods Use of temporary cover crops Temporary mix installed in the spring Invasive species monitored over summer Cover crops harvested or clipped late summer/fall Light disking in fall Dormant seeding of native mix (no additional mulch needed) * Gleason, Robert A. 2003.

What information should be included? Activities that will be used for 5-year establishment Species to be monitored and controlled How will problem species be controlled? When will activities be conducted? How and when will site inspection occur (inspection schedule)? Contingency plan for any corrective measures WCA - Five year vegetation management plan required to ensure establishment of desired vegetation Routine - post planting mow upland 1 st and 2 nd yr Threshold levels for invasive species is variable - tolerance for reed canary grass is very low, hybrid cattail and eastern cattail tolerance is somewhat higher but may change Maintenance Schedule BWSR Bank Site Kanabec County Mowed 1 st Year Year 1 Mow upland areas and wetland fringe (when moisture levels allow) to 6-8 inches through September as needed to prevent seeding of annual weeds. Spot treat invasive weeds in wetland and upland portions of the project. Year 2 Etc.
