1 Ecosystem Services, Biodiversity, and Property Values in an Urbanizing Region Kevin Bigsby, Chris Clary, Nyeema Harris, George Hess, Megan Lawler, Melissa McHale, Alicia Raimondi, Shawn Shifflett, Neal Wisenbaker

2 (World Population Prospects 2007, United Nations) Introduction US Population Growth

3 Introduction Land Use Change

4 (Foley et al. 2005, Science) Introduction Impacts of land use change

5 Biophysical Approach: Does managing for ecosystem services in a highly urbanizing region inherently encompass areas of conservation concern? Valuation Approach: Will the monetary value of ecosystem services outcompete property value in a rapidly developing area? Introduction Research Questions

6 Study Area T RIANGLE R EGION, N ORTH C AROLINA Introduction Study Area

7 BIODIVERSITY: HABITAT QUALITY AND RARITY CARBON STORAGE CARBON SEQUESTRATION RESERVIOR HYDROPOWER PRODUCTION WATER PURIFICATION: NUTRIENT RETENTION AVOIDED RESERVIOR SEDIMENTATION MANAGED TIMBER PRODUCTION CROP POLLINATION InVEST Methods

16 Methods Ecosystem Service Quartiles F ORESTS LOCATED NEAR A G AREAS AND W ETLANDS IN F OURTH Q UARTILE URBAN AREAS IN FIRST QUARTILE

17 V ERTEBRATE SPECIES RICHNESS 98%96% 99%100% Modeled species richness does not vary significantly according to the Ecosystem service quartile. NO CONCORDANCE Result Biodiversity Metric 1:

18 Element Occurrences Completeness – n (%) of total occurrences Representation – n (%) of unique occurrences Ecosystem services capture to identity, but not the spatial distribution of element occurrences MODERATE CONCORDANCE E LEMENT OCCURRENCES Result Biodiversity Metric 2:

19 S IGNIFICANT N ATURAL H ERITAGE A REAS Ecosystem services do not efficiently protect SNHAs LOW CONCORDANCE Result Biodiversity Metric 3:

20 Interpretations varied depending on the biodiversity metrics Overall, low concordance between biodiversity and ecosystems services Win-win locations do exist in a urbanizing region Using an ecosystem approach to conserve biodiversity is not efficient Summary Ecosystem Services & Biodiversity

21 Biophysical Approach: Does managing for ecosystem services in a highly urbanizing region inherently encompass areas of conservation concern? Valuation Approach: Will the monetary value of ecosystem services outcompete property value in a rapidly developing area? Part II Ecosystem Service Valuation

22 Ecosystem Services Carbon Sequestration Water Purification: Nutrient Retention Crop Pollination InVEST Methods How are we comparing values? Property Value vs. Multiple Ecosystem Service Value 20 year values with a 1% discount rate Theme There are reasons to establish contracts early for ecosystem service conservation.
