Grazin�, farming, or other activities have typically distuzbed C quality natura� communities, but <br />with proper znanagernent technigucs such as prescribed bu�-ning, could be upgraded to a hi�her <br />quality. <br />D quality natural communities are severeiy disturbed and can only he restored to a higher quality <br />with considerable effort and expense. Poor quality natural communities have generally hacf their <br />characteristic plant species assemblage replaced by weedier native species and/or nonnative <br />species. <br />Uplanci sites assigned an NA do not meet minimum standards to be classified as a natural <br />community or are human created environments such as conifer plantations and oId fields. The <br />ecologicaI ranking for each site is given with its Cotnmunity Description in this report. <br />One major area where this inventory cffort differs from DNR Natural Herita�e Program <br />standards is in the "minimum size" criteria. The DNR NHP standard for minimum size vanes <br />for each community Eype with the minimum size for some cornm�nities being over 40 acres. <br />During this study, all native plant comrr�unities within the five parks stuc�ied were visited and <br />inventoried. <br />Because sites with a rank of "C" or better are very rare in urban areas, readers should not be <br />alarmed at the lower rank of some natural communities within the study area. Although the <br />qualitati.ve rank is a reflectio� of current conditions, it does not take into account a natural <br />community's potential to improve under active management. Restoration is an important as�ect <br />to take into account in the case of Roseviile Parks since the City has an expressed desirc to <br />actively mana�e these areas and enable their recovery/improvement, where possible. <br />City of Roseti•ifle 61 <br />Pr�rks Natural Resaurce lYlc�lrngemerat <br />
