Santa Catalina Island The Galapagos of the U. S. Presented by: Margee Haines, Bruce Rudy, Nuyi Tao
Santa Catalina Facts • Volcanic Island, 22 miles from CA • 50, 000 acres • Widest diversity of plants and animals among Channel Islands • Economic, recreational, and scientific uses
Ecology of Santa Catalina • Rugged mountains, shallow soils, and an arid climate • Habitat diversity: coastal-sage scrub, grasslands, oak woodland, dunes, and beaches • High plant and animal diversity as well as endemism
Santa Catalina Land Use Facts Private Ownership (1%) Santa Catalina Island Company (11%) Santa Catalina Conservancy (88%)
Historic Human Impacts • Introduction of exotic Plants and Animals – Catalina Thistle, Fennel – Bison, Goats, Pigs, Mule Deer • Livestock and Mining Operations – – Disruption of Native Plants Stream Sedimentation Erosion Hydraulic Alteration
Threat #1: Human Impacts • Resident population of 4, 000; 1, 000 visitors per year. • Avalon residential development • Over 200 miles of roads
Threat #2: Invasive Species • Biggest long-term challenge • >30% plant species aren’t native • Threaten natural diversity • Out-compete natives
Threat #3: Sensitive Species • Catalina Island Fox • Bald Eagles • Catalina Mahogany • Beechey Ground Squirrel • Rattleless Rattlesnake • Santa Catalina Monkey Flower
The Santa Catalina Conservancy • Established in 1972 by Wrigley family • Acquired 88% of Island in 1975 (42, 000 acres) • Funded by membership dues, large donors and revenue producing operations Mission: To maintain the health of the Island’s species by preserving and restoring habitat and allowing ecological processes to function without major human intervention for future generation.
Conservancy Partnerships • Local Organizations – Local and National chapters of the Sierra Club – Eagles' Nest Lodge – Ameri. Corps NCCC west region – The Catalina Island Women’s Forum – Volunteer Naturalist Corps • Local Universities – University of Southern California – University of Reno - Geology
Conservancy Structure • Board of Directors elected by life members • 50 paid staff including 4 -person Administrative Office • Informal Consultation from Business and Recreational Users • Formal Consultation from County and State Agencies • Recruitment of Volunteers
Conservancy Goals • Goal #1: Conservation – Habitat Restoration – Control Invasive Species – Maintenance of Native Animals (Island Fox Breeding Program)
Conservancy Goals (cont. ) • Goal #2: Education – Natural History Programs – Outings and Workshops – School Programs
Conservancy Goals (cont. ) Bicycle Map • Goal #3: Recreation – Hiking – Camping – Biking – Jeep Eco-Tours – Horseback riding
Activities and Projects • Native Plant Nursery • Hayfield Restoration • Island Fox Breeding Program • Rare and Endangered Plant Monitoring
Research • Scientific Research – Established understanding of Island’s biophysical processes • Used to begin restoration process
Monitoring • Plant or vegetation monitoring – – • Invasive Weed Mapping Rare Plant Population Searches and Mapping Island Vegetation Map Wetland plant communities Land Bird surveys – Understand how birds and other animals are responding to changes in the island's vegetation
Obstacles • Staff members – Lack background/ education in conservation issues – Lack awareness of island’s unique ecology
Obstacles (cont. ) • Tourism • Public/resident-lack of concern and education • Need more coordination of restoration activities
Opportunities • Support from top management • Reasonable funding • Huge population in Southern CA to Volunteer • Expand Partnerships with Research Universities
Future of the Island • The Galapagos of the U. S. • Multiple Opportunities exist • Success through Collaboration
Conservancy Report Card Grumbine’s Themes Discussion Hierarchical Context Aware of connection btw abiotic/biotic components Ecological Integrity Consistent with Mission, reinforced by projects Data Collection Strong understanding of habitat/species/population Monitoring Established programs, average feedback Adaptive Management Familiar with terminology, average application Interagency Cooperation Exempt, but in need of cooperation Organizational Change Top heavy, need stakeholder input and feedback Humans Embedded in Nature Awareness but too much human emphasis The Grade
