Some strategies for enhancing or restoring hydrology anc� native plant communities in wetlands <br />include the followinj: <br />• Ditches should be blocked or outlets raised and tile lines removcd ar altered to resEore <br />the orijinal hydrologic regime. <br />• Remove or control invasive exotic species. Removal of exotic species such as reed <br />canary �rass and purple loosestrife typically involves hand pulling, herhicide control, <br />prescribed burns, excavation or a combination of management strategies. <br />• Establish a vegetative buffer around wetland areas, to filter runoff, slow stormwater <br />�1ows, and provide essential upland habitat needed by many species that use both <br />wetlands and uplands as habitat during their lifecycles. <br />Forest Management <br />Most of the forest areas in the study area have becn grazed at varying Zcvels in the pasC, and in <br />some cases were logged. Excessive i�uman disturbance encourages invasion by aggressive <br />exotic species-particularly buckthorn and Tartarian honeysuckle. Fragmentation also reduces the <br />value of the forest community for wildlife species such as migraiory songbirds that require <br />"interior" forest areas that are well buffered from human disturbances. <br />Foilowing are management strategies for maintaining and restoring the diversity and health of <br />forest coznmunities: <br />• Avoid cutting trees in areas containing exotic shrub species. Where cutting trees is <br />necessary, cut exotic shrubs and treat with a basal application of an appropriate <br />herbicide. Where developments are proposed within or adjacent to forest areas, <br />removal and treatment of exotic shrubs could be incorporated into the overall site <br />preparation process. <br />• Slow growing and mast-hearing trees such as oak and butternut should be given <br />particular protection due to their value to wildlife. Other trees also serve as important <br />food sources for wildiife including maples, elms, aspens, basswoad and birch_ <br />� Large trees, particularly those containing cavi#ics, should not be removed unless th_ey <br />present a safety hazard.
