particularly if other sources of native popuiations are not available nearby. Planning <br />should emphasize improving connectivity for natural areas within parks as well as to <br />areas outside of the parks/city. Connections between communities along natural <br />corridors can hclp to maintain diversity and health by allowing plants and animals to <br />mi�rate between larger natural areas. <br />• People are part of nat�re. The decisions and actions of humans have been a major <br />force shaping the natural resources af Roseville for inillennia. Humans and their <br />values will continue to be an important component in shaping the future of natural <br />areas. Restoring natural communities in city parks will continue to involve planning <br />for a balance oF integration between urban land uses and maintaining or improving <br />nearby natural areas. <br />• Species are interdependent, and our knowledge of all the interactions vvi#hin <br />natural communities is limited. Restoring natural comnnunities is a relativcly <br />young field in science, and new information will continue to come to the fore. <br />Adaptive Managenaent in the restoration of natural communities requiz-es keepi�g <br />abreasC of the most up-to-date information and integrating it with currenE practices. <br />• Intradac#ions of nonnative plants should be limited Certain nonnative species are <br />known to be invasive and reduce nativc diversity, the quality of habitat. When new <br />landscaping is created, any nonnative plant materials proposed for use should be <br />reviewed to prevent the unintentional introduction of a plant species that will need to <br />be controlled in adjoining natural areas in the future. <br />� Restoration of natural communities txaust consider long time frames. Because <br />natural communiiies are complex systems that can take years or decades to <br />substantially respond to resource management, patiet�ce and a long-term commitment <br />is required. For example, thc positive effects of appropriate managem.ent in som.e <br />debraded forests may Eake one to several tree generations to be reaIized. In the case <br />the initial goal may not be rcached for over 100 years. Conversely, some natural <br />communities respond quickly to management and may significant�y improve in a <br />matter of years, or decades. <br />City of Roseville 4 <br />Parks Natt�ral Resotrrce rYla�:a�etne�et <br />
