t • Oak Hill (Area A): Approximately 120 acres of mixed oak woodland, savanna, and prairie in BLM and private ownership. • Cantrell Ridge (Area B): Approximately 400 acres of mixed oak woodland, savanna, prairie and headwater streams of Willow and Coyote Creeks, primarily in private ownership. • Greenhill Ridge (Area C): Approximately 250 acres of savanna and oak woodland. • Murray Hill (Area D): Approximately 1,700 acres of mixed oak woodland, savanna, prairie, and headwater streams of Spencer and Coyote Creeks, primarily in private ownership with some TNC ownership. • Wild Iris Ridge (Area E): Approximately 500 acres of savanna, prairie, oak woodland, and headwater streams of Spencer and Willow Creeks in private and City ownership (includes 123 acre City owned Wild Iris Ridge site). • Upper Spencer Creek (Area F): Approximately 1,300 acres of mixed savanna, prairie, oak woodland, and headwater streams of Spencer Creek. • Upper Russel Creek (Area G): Approximately 250 acres of mixed savanna and woodland and headwater streams of Russel Creek. • Upper Russel Creek (Area H): Approximately 500 acres of mixed oak -ash woodland along Spencer Creek and the associated floodplain. Goal 2: Habitat Management and Enhancement Actively manage and enhance important habitat areas in the ridgeline area to help sustain their integrity and long -term viability. Recommended Actions and Strategies: A. Develop detailed management plans for public and land trust properties to help guide long -term site maintenance and enhancement activities and budgeting for those activities. Management plans should include documentation of key site attributes (historic conditions, existing conditions, and anticipated future conditions); conservation issues and threats; habitat management goals; and a schedule of routine and long -term management actions. B. Provide technical assistance to help private property owners develop management plans for their properties that will lead to enhancement of habitat conditions. These efforts should focus on properties that possess high habitat values or that are contiguous to other large blocks of habitat on public or land trust lands. A number of federal, state, and local agencies and organizations can provide assistance in this area through various programs (Appendix -A). C. Use a variety of management and maintenance techniques to enhance and preserve habitat quality on public, land trust, and private lands. Key management activities in the ridgeline area would likely include: • Weed management: Weed management is a key activity for ensuring the long -term survival of native plant and wildlife communities. Weed management should focus on control of highly invasive non - native species such as Armenian blackberry, Scot's broom, false brome, English ivy, and other emerging threats. Special attention should be given to areas containing known rare plant and animal populations and control of newly colonizing weed populations. • Enhancement of native vegetation community: Native trees, shrubs, grasses, and forbs should be introduced where appropriate to increase native cover and diversity (i.e. planting riparian vegetation along waterways, re- introducing native prairie species, increasing diversity of shrub and herbaceous species in oak woodlands). • Maintenance of habitat structure: Savanna, oak woodland, and prairie habitats all require special management activities to help maintain their open structure and vegetation community. This may be achieved through a number of techniques such as mowing and prescribed fire (where feasible) to prevent woody vegetation from establishing in prairie s and 2
