• <br />• <br />• <br />Woolen's Park Wetland Bank Part B: Appendix 2 <br />Critical Connections Ecological Services, Inc. <br />January, 17`h 2012 <br />Page 2 of 8 <br />Site Preparation <br />Site preparation will occur in the later fall, winter, and early spring of the first year of wetland <br />restoration. Site preparation will be implemented with the ultimate goals of removing woody and <br />herbaceous biomass that has accumulated as a result of prolonged fire suppression, invasive and <br />aggressive exotic species establishment, and drainage of wetlands. Removal of accumulated saturated <br />herbaceous biomass is critical to promoting the germination and establishment of an existing viable <br />native seed bank. Prescribed burning alone is not able to remove accumulated saturated herbaceous <br />biomass from the peatland surface; mechanical removal during frozen soil conditional is necessary. <br />Removal of native and exotic trees and shrubs is critical to reducing competition from shading, and <br />removing volatile woody biomass to promote safe, efficient, and effective prescribed burning. <br />Following the removal of accumulated herbaceous and woody biomass, herbicide treatments of invasive <br />species and woody plant stumps will be implemented. <br />Seed Mixes and Plant Materials <br />Data collected from the wetland bank site indicates the potential presence of a suppressed and diverse <br />native seed bank. This vegetation establishment and restoration approach will rely on an existing viable <br />(but suppressed) native seed bank as the primary source of plant propagules for the re- vegetation of the <br />wetland bank site. Such an approach has been successfully implemented on similar peatland restoration <br />sites in adjacent municipalities within the Anoka Sand Plain. When necessary, native vegetation re- <br />establishment will be augmented with local ecotype native seed mixes in areas where the existing native <br />seed bank is not viable, depleted, and /or is not performing adequately. Origin certified Minnesota <br />Yellow Tag seed will be used when \any additional seeding is needed. The following are seed mixes <br />developed by CCES for use in restoration of, plant communities that are found within the site boundary. <br />Table 1.
