Outline • Current protection • Definitions • History • Principles of Reserve Design • Corridors • How much is enough? • Methods of Reserve Design
What is a protected area? • IUCN “an area of land and/or sea especially dedicated to the protection and maintenance of biological diversity and of natural and associated cultural resources, and managed through legal or other effective measures”. • What % of earth is currently protected?
What is a reserve system and how does it differ from a protected area? • Who categorizes protected areas? • What are some of the areas in the world with the greatest % of protected areas?
History of Protected Areas Tribal peoples set aside some areas for protection First national park? 1962 First World Parks Congress 1992 Convention on Biological Diversity - each signee must first establish a system of protected areas 1992 Fourth Congress on National Parks and Protected areas set a goal of at least 10% protection of each major biome by 2000
“Ad hoc approaches to conservation planning have resulted in a system of conservation areas that are biased towards areas of high elevation, steeper slopes, and poorer soils.” (Robert L. Pressey)
Biological Objectives of Reserves(Soule & Simberloff 1986) • Preservation of ecosystems • Preservation of biodiversity • Focal species of interest • Perpetuation of plants and animals for harvest • Goals will affect reserve design
Critical Issues In Reserve Success(Groom et al 2007) • Size • Heterogeneity • Landscape Context • Connectivity • Buffer Zones • Humans must be included
Size • Bigger is better - Why? • SLOSS debate (Burkley 1989)
Heterogeneity and Dynamics • More heterogeneity is desired - Why? Important related principles • Minimum dynamic area • Patch dynamics (‘shifting mosaic’) • Climate Change
Buffers • Developing multiple buffer zones can be a critical tool - Biosphere model • Mum Model • Buffer may need to be gradual or abrupt • What circumstances do we want gradual? • What circumstances for abrupt?
Landscape Context • Patch dynamics inside are influenced by outside (Buechner 1987) • Boundaries are critical (Schonewald-Cox and Bayless 1986) • Ties in with: • Matrix considerations, Edge effects, • Necessary buffer depends on focal species and research is needed
Connectivity • Corridors are needed within and between reserves • Why? • Structural vs functional components? • Weaknesses of Corridors?
Corridors • Must determine target species and objective or they can become sink • Landscape context also important in determining size and shape • Nodes/Networks/MUM model (Noss and Harris 1986) • Linkage Zones
The MBC is defined as: "A system of land-use planning that features areas under various administrative arrangements including core natural areas, buffer zones, multiple use zones, and corridor areas. These are organized and consolidated in a manner that offers environmental benefits and services to Central America and the world. The MBC will provide opportunities for people to participate and promote investment in the conservation and sustainable use of natural resources. The purpose is to improve the quality of life of the Mesoamericans" (WRI, 2001).
Human Component • Must work with people and include humans in process • “Paper parks” • Concept of “biocultural restoration” (involve local people in all aspects) • Biosphere reserve model

Advanced Tools for Conservation Planning What private organization has the largest system of reserves? How do they select reserve areas?
What individual and university research program created GAP analysis?
What is special about 10%? 1992 Fourth Congress on National Parks and Protected areas set a goal of at least 10% protection of each major biome by 2000 2003reached 11.5% and 10% in 9 out of 13 biomes
Global Gap Analysis ProjectRodriques et al 2004 Overlay two main databases World Database on protected areas Distributional data for 11,633 species Mammals, amphibians, freshwater turtles, tortoises, birds Main findings 1424 species not protected at all (804 threatened) Amphibians had lowest representation 46% of PA in tropics but 76% of world’s species
Conclusions • 10% will not achieve conservation goals • Biodiversity is not evenly distributed across the globe • Need more protected areas in the tropics • Suggest level of threat and irreplaceability could guide conservation planning
Biosphere Reserves • (482 in 102 countries) • UNESCO man in the biosphere program started 1977 • Representative of a major biogeographic area - Contain landscapes, ecosystems or animal and plant species which need to be conserved • Functions: 1) biodiversity conservation, 2) environmentally sound sustainable development, 3) support research, monitoring and education
