RESILIENCE AND INTACTNESS A Manager’s Perspective Why does it matter? • Global change is occurring at an increasing rate • Climate change • Accelerating demand for resources • Intact and Resilient Landscapes • Support functioning habitats, species • Absorb change • Provide ecosystem services • Alaska is largely intact • How do we know? • How do we maintain? • Where and how do we authorize uses? A Few Factoids • BLM manages about 245 million acres and 700 million subsurface acres in the United States • Over 70 million acres and 200 million subsurface acres in Alaska • Multiple Use and Sustained Yield • Energy, communications, mining, grazing • Wildlife habitat, cultural and heritage resources • Inherently landscape-scale Landscape Approach – Major Components Regional Assessments Monitoring for Adaptive Management Projects and Permits Science and Geospatial Services Regional Conservation and Development Strategies Land Use Plans Landscape Goals • Maintain Viable Ecosystems • Resilient to Global Change • Climate change • Development • Fire • Invasive species • Provide Ecosystem Services • Commodities – energy, minerals • Quality of life – recreation, visual • Community sustainability – subsistence, water quality Landscape Management • Assumes human footprint is the main threat • Maintain remaining large intact areas • The best of what’s left • Areas of Critical Environmental Concern • Concentrate uses in already disturbed areas • Co-locate uses • Create linear corridors • Maintain or reconnect large intact areas • Land acquisition, easements, etc. • Restoration • Movement corridors Another way? • ACECs with boundaries that adapt to changing conditions • Locate uses in resilient areas/Conserve fragile areas • Disperse uses in more resilient areas that can absorb change • Avoid concentrated uses that may create barriers • Alternatives that address different climate scenarios • Consider alternative future scenarios • Attribute based alternatives • Manage for resources across time and space, not in fixed locations • Mitigation based alternatives • Restore as we go, identify limits of change • Allow for cascading mitigation as conditions change Managing Intact Landscapes • How large is a large landscape? • Static and dynamic landscapes • What constitutes crucial habitat in an intact landscape? • How much development could cause barriers or • • • • fragmentation? Should uses be concentrated or dispersed? How do we assess “other than development” impacts to intactness? How do we mitigate long-term projects on a changing landscape? How do we assist communities in adapting to global change?
