More than 200 species are in rare, endangeredand near endangered status.Expansion of rubber production is a major threat, whichincreases with climate change. However, conditions inexisting protected areas will change drastically by 2050.

Gaoligongshan National Nature Reserve Baoshan PrefectureA Biodiversity Hotspot / UNESCO Biosphere ReserveApprox. 405,500 ha. of highly diverse montane forestwith a extraordinary mix of diverse flora and fauna.The highest areas have been designated as an strictconservation, with no visitors allowed. Climaticconditions in these higher elevation habitats aredrastically altered by 2050.
  41. 41. Incorporating adaptation scenarios to predictspatial species distribution of alpine plants 1. Does alpine plants shift upward under warming temperature in SW China? 2. If yes, what is the rate of range shift to No adaptation, Local adaptation Adaptation corresponding climate local extinction by physio- through range morphological shift change? change, or even speciation 3. If not, what are the adaptation strategies? Adaptation scenarios Focal plants: Rhododendron spp.
  42. 42. Two ways to design linkages for climate change The “old” (2005) New way: way: linked dynamic corridors for diverse models land facets P. BEIER & B. BROST, 2010 Climate envelope models Facet: One of the flat… perform no polished surfaces cut on abetter than chance gemstone(Beale et al. 2008.PNAS 104:14908
  43. 43. Land facet: a landscape polygon ofrelatively uniform topography and soil Wessels et al. 1999. Biological Conservation
  44. 44. Land facets as drivers of biodiversity Soil type Insolation Topographic position ElevationPlants &animals are(and will be) Climatea function of: ?The state-factor model of ecosystems.Hans Jenny (1941); Amundson & Jenny (1997)
  45. 45. These variables define land facets. Land facets will interact with future climate to support new assemblages of plants and animals. Distribution of plants & animals
  46. 46. “Conservethe arenas of biologicalactivity rather than thetemporary occupants of those arenas.” (Hunter et al. 1988)
  47. 47. The approach should identify a continuous strand of each land facet, and a strand with high diversity of facets. These will help plants & animals shift their ranges as climate changeP. BEIER & B. BROST, 2010Conservation Biology
  48. 48. Examples of land facets• mid-elevation, steepridges with rocky soils• low-elevation, high-insolation (sunny) flatareas with thick soilsIf good soil maps arelacking, facets can bedefined solely ontopographic variables. Conserving the arenas, not the actors: land facets as biodiversity surrogates in planning for climate change P. BEIER & B. BROST, 2010, Conservation Biology
  49. 49. Join All Corridors Add a riparian corridor if neededFacet A CorridorFacet B CorridorFacet C CorridorCorridor withinterspersed facetsMany soil maps arenot useful.If needed, usepresence of water orriparian plants to mapa “moist soil facet” P. BEIER & B. BROST, 2010, Conservation Biology
  50. 50. Advantages of using land facets to define corridors• Useful where no vegetation maps exist.• No bias to include “data-rich” areas in the design.• Not subject to error propagation from linked, highly uncertain models.• Not subject to error compounding from projecting 50-100 years into the future. P. BEIER & B. BROST, 2010, Conservation Biology
  51. 51. Yunnan Province, ChinaAnnual Net Primary Productivity (NPP) Annual net primary productivity (NPP) averaged over a period from 2000 to 2006, based on MOD17 – MODIS Global Terrestrial Net Primary Production estimates derived from satellite remote sensing data at a resolution of 250m2 (Running et al., 2005). Projected NPP in 2050 is calculated based on increase (or decrease) of zonal areas.
  52. 52. Results Can expect significant climatic change Can expect significant impact on ecosystem and species / productivity Can expect species and ecosystems shift Hotspots of change/ change-ecotones identified High risk ecotypes identifiedImplications for Environmental Monitoring Need to consider the impact of climate change on monitoring and conservation design Target climate vulnerable ecotypes and species Landscape approach for climate change adaptation
