For the purposes of the i�zventory portion af this project, a"natural community" is a distinctive <br />group of plants and animals that typicaliy occur together, and axe native to the area, such as a <br />sand-gravei prairie or dry oak savanna. <br />The inventory and managernent recommendations included in this report suggest that natural <br />areas be evaluated on an ecological basis. Sitr►ply put, an ecosystem (or "habitat") is where <br />things live. An ecosystem includes the interacting group of physicai eiements (soil, water, <br />etc.) and biologicat elements inciuding plants, animals and human communities. All of <br />these elements and their linkages to other natural areas are considered in this report. <br />Science suggests that a key measure of ecosystem hea�th is the diversity of native plants and <br />animals present in a given area. Healthy, diverse ecosystems are a desirable goal because they <br />provide for the basic needs of all living things, and allow the Iandscape to adapt to chan;ing <br />conditions. And importantly, the unique plant communities found in Roseville serve to express <br />the local character of the City, providing residents with n sense of pince. <br />OVERALL GOAL OF INVENTURY AND MANAG�MENT PLAN <br />To inventory existing naturai communities to create sound natural resour�e mana�ement plans <br />for each oE the five parks. <br />OBJECTiVES <br />The specific objectives identified for the five parks included in this study are: <br />■ To identify and inventory natural areas in each park. <br />• To develop specific, practical, and scicnce-supported recommendations for <br />management of natural communities. <br />GUID�NG ECOLOGIC�L PRINCIPALS <br />Some ecological principles that are itnportant components Qf protecting or enhancing natural <br />areas in City Parks include the following: <br />• The health of naturai communities depends on their size. In general, srrialler and <br />�nore fraainented communities support fewer species, are more vulnerable to lacal <br />extinction and invasions, and are less able ta nnaintain or recovcr their diversity, <br />City of Roseville <br />Parks Ncttru-c�l Resocerce hlanageme�7t <br />
