1. Ecosystem Management And Preservation

2. Reserves Reserves – any natural or semi-natural ecosystem that is protected from most forms of human use - however, we must remember that reserves go by several different names - national parks, refuges, national monuments, national wilderness areas, preserves and more; with many regional and local versions of reserves too

3. Reserve Selection Reserves are developed by a variety of mechanisms: 1.Government action – usually at a national level, but may happen at regional or local level as well 2.Land purchases by private individuals and conservation organizations (such as The Nature Conservancy) 3.Actions of indigenous peoples and traditional societies 4.Development of biological field stations – usually combine biodiversity protection and research with education

5. Arctic National Wildlife Refuge

6. Houston Toad

8. The Nature Conservancy – active since 1951 in the US

9. Nature Reserves Managed by native people – Arnheim land, Australia

10. Biological field stations as Reserves

11. Creating Preserves Creating new reserves requires the following steps: 1.Identifying priorities for conservation 2.Determining those areas of each country that should be protected to meet conservation priorities 3.Linking new protected areas to existing conservation networks, using techniques such as gap analysis

12. Setting Priorities 1. Distinctiveness (or irrereplaceability) – an ecosystem that consists of primarily rare or endemic species or that has other unusual attributes (scenic value, geological features) is given highest priority 2.Endangerment (or vulnerability) – species in danger of extinction are of greater concern than those that are not 3.Utility – species that have present or potential value to people are given more conservation priority than species of no obvious use to people

13. Distinctive Ecosystem – Peat Bogs

14. Rarity – European Bison

15. European Bison Distribution Light green – Holocene range; Dark green – late Middle Ages; Red – current distribution

16. Utility – wild apple Kazakhstan

18. Determining which areas should be protected 1. The Species Approach – focus on focal species (indicators, flagship or umbrella species) 2.The Ecosystem approach – save enough representatives of each ecosystem (at least 10%) can save most biodiversity 3.The Hotspot Approach – save areas that have high numbers of species – especially rare or endemic species

19. Flagship species – Eurasian Lynx

20. Umbrella Species – Northern Spotted Owl

21. Indicator species – Freshwater mussels

22. Ecosystem Classification

23. Ponderosa Pine Forest

24. Hotspots Hot spots or centers of diversity – are areas with high levels of species diversity and usually also high levels of endemism – thus become key areas to preserve – at least 34 global hotspots have been identified

25. 34 Biodiversity Hotspots

33. Hotspots on Mt. Mulanje, Malawi

34. Rare and Endangered Species in the US Andy Dobson examined the distributions of 900 rare and endangered species in the US and found: 0.8 to 3.3 percent of the land in the lower 48 states provides habitat for just over 50% of the rare and endangered species At risk reptiles and amphibians occupy 0.68% of US land; endangered fish take up the most space - 3.33 % San Diego County, California is a hot spot for endangered fish, mammals and plants Santa Cruz County, California is a hot spot for endangered arthropods, reptiles, amphibians, and plants 4 counties in Hawaii are hot spots for endangered birds and plants

35. Gap Analysis 1.Data are compiled on the species, ecosystems and physical features of the region – sometimes referred to as conservation units or ecoregions 2.Conservation goals are identified, such as amount of area to be protected for each ecosystem 3.Existing conservation areas are reviewed to determine what is protected already and what is not (identifying the gaps) 4.Additional areas are identified to help meet the conservation goals (filling the gaps) 5.Additional areas are acquired for conservation and a management plan is developed and implemented 6.The new protected areas are monitored and management plans adjusted

37. Idaho – Cedar-Hemlock Forest

38. Idaho – Western Juniper Shrubland

39. General issues in reserve design – the 4 Rs Representation – the protected area should contain as many aspects of biodiversity (populations, species, habitats, etc) as possible Resiliency – protected areas must be sufficiently large to maintain all aspects of biodiversity in a healthy condition for the foreseeable future, including the predicted impacts of climate change Redundancy – protected areas must include enough examples of each aspect of biodiversity to ensure its long- term existence in the face of future uncertainties Reality – the must be sufficient funds and political will, not only to acquire and protect lands, but also to subsequently regulate and manage the protected areas

40. More specific questions: How large must a nature reserve be to effectively protect biodiversity? Is it better to have a single large protected area or multiple smaller reserves? How many individuals of an endangered species must be included in a protected area to prevent extinction of the species? What is the best shape for a nature reserve? When a network of protected areas is created, should the areas be close together or far apart? Should they be connected to each other or isolated from each other?

45. Basic Reserve Design 1.Big reserve better than small 2.One big better than several small in same habitat 3.Closer is better than spread out 4.Clustered is better than linear 5.Having corridors is better than not 6.Circular is better than other shapes
