EFFECTIVE POLICY RESPONSES TO CHANGES IN BIODIVERSITY ARE ONLY POSSIBLE WITH ADAPTABLE ANALYTIC TOOLS THAT LEVERAGE THE INFLUX OF DATA FROM BIODIVERSITY OBSERVATION SYSTEMS. SUCH ANALYTIC TOOLS MUST ALSO BE STREAMLINED AND READILY MASTERED BY RESEARCHERS MAKING SCIENTIFIC RECOMMENDATIONS. IN THIS PROJECT WE WILL CREATE SOFTWARE TO ASSESS BIODIVERSITY CHANGE INDICATORS BY BUILDING ON THE RECENTLY DEVELOPED SOFTWARE WALLACE AS A NEW GEO BON IN A BOX TOOL. WALLACE IS AN R-BASED APPLICATION WITH A GRAPHICAL USER INTERFACE THAT SUPPORTS SPECIES DISTRIBUTION MODELING (SDM) IN A REPRODUCIBLE FLEXIBLE AND EXTENSIBLE PLATFORM TO FACILITATE A WIDE RANGE OF ECOLOGICAL ANALYSES. THESE MODELS CHARACTERIZE ENVIRONMENTAL SUITABILITY FOR SPECIES AND CAN BE USED TO ESTIMATE SPECIES GEOGRAPHIC DISTRIBUTIONS A GEO BON ESSENTIAL BIODIVERSITY VARIABLE (EBV). WALLACE HARNESSES BIODIVERSITY DATA FROM ONLINE DATABASES OR USER INPUT ASSEMBLES A VARIETY OF TOOLS FOR BUILDING AND EVALUATING MODELS AND OFFERS GUIDANCE FOR IMPORTANT CONCEPTUAL AND METHODOLOGICAL ISSUES. CRITICALLY ITS MODULAR NATURE FACILITATES THE ADDITION OF NEW CUTTING-EDGE INNOVATIONS BY OTHER PROGRAMMERS AS WE PROPOSE HERE. TO EXPAND WALLACE AS A NEW BON IN A BOX WE WILL DEVELOP TWO NEW R PACKAGES TO BE INTEGRATED AS NEW MODULES FOR WALLACE S WORKFLOW TO FACILITATE BIODIVERSITY CHANGE INDICATOR CALCULATIONS FOR GEO BON ASSESSMENT AND REPORTING IN COLLABORATION WITH THE COLOMBIA BON AS A MODEL. THE FIRST PACKAGE WILL USE SINGLE SPECIES RANGE MAPS IN CONJUNCTION WITH REMOTELY SENSED (RS) PRODUCTS TO ESTIMATE THE SPECIES CURRENT RANGE. IT WILL HARNESS RS PRODUCTS DERIVED FROM NASA (AND OTHER) SATELLITES INCLUDING PERCENT FOREST COVER VEGETATION CLASSES AND NDVI WHICH CAN BE SPATIO-TEMPORALLY MATCHED WITH RECENT IN SITU OBSERVATIONS OF SPECIES OCCURRENCE TO DETERMINE HABITAT TOLERANCES (E.G. TO LAND USE CHANGE). THE SECOND PACKAGE WILL ALLOW CALCULATION OF KEY INDICATORS INCLUDING SINGLE-SPECIES BIODIVERSITY CHANGE INDICATORS SUCH AS RANGE SIZE EXTENT OF OCCURRENCE PERCENT SUITABLE LAND COVER OR PROJECTED TRENDS UNDER FUTURE SCENARIOS AT MULTIPLE SPATIAL EXTENTS. CALCULATIONS WILL ALSO INCLUDE MULTI-SPECIES INDICATORS SUCH AS THE EBV TAXONOMIC DIVERSITY AND OTHERS NOT CURRENTLY IMPLEMENTED THROUGH OTHER BON IN A BOX TOOLS WITH A FOCUS ON ONES MOST USEFUL AT REGIONAL SCALES. MODULE OUTPUTS FROM WALLACE WILL BE DESIGNED TO FEED DIRECTLY INTO OTHER BON IN A BOX TOOLS SUCH AS OUR INTERNATIONAL COLLABORATOR INSTITUTO HUMBOLDT S BIOMODELOS. BIOMODELOS IS A WEB APPLICATION ENABLING EXPERT VALIDATION OF SPECIES RANGE ESTIMATES IN SUPPORT OF THE COLOMBIA BON. WE WILL ALSO DEVELOP TRAINING MATERIALS FOR WALLACE TARGETING CONSERVATION PRACTITIONERS THAT REFLECT BEST PRACTICES FOR USING SDM FOR BIODIVERSITY CHANGE INDICATOR CALCULATIONS RESOURCE MANAGEMENT AND BIODIVERSITY CONSERVATION DECISION-MAKING. OUR PROJECT RESULTS WILL ADDRESS CHALLENGES TO OVERCOMING THE GAP BETWEEN BEST MODELING PRACTICES AND BIODIVERSITY CONSERVATION DECISION-MAKING AND WILL FACILITATE RESPONSIBLE REPORTING ON BIODIVERSITY BY NATIONAL BONS. VIA FOCUS ON THE DEVELOPMENT AND ENHANCEMENT OF OPEN-SOURCE USER-FRIENDLY SOFTWARE TO CONTRIBUTE TO BON IN A BOX OUR PROPOSAL WILL ADVANCE BROAD APPLICATION EXPLORATION VISUALIZATION AND UNDERSTANDING OF EBVS AND GENERATION OF EBV DATA. FURTHERMORE DEVELOPING A CONNECTION BETWEEN WALLACE AND BIOMODELOS ANOTHER BON IN A BOX TOOL WILL BE VALUABLE FOR FUTURE INTERFACING WITH EFFORTS AT IUCN BIEN (THE BOTANICAL INFORMATION AND ECOLOGY NETWORK) AND OTHER SIMILAR PROJECTS THAT USE SDM PREDICTIONS AS INPUTS. FINALLY ALTHOUGH WE WILL FOCUS DEVELOPMENT OF OUR BON IN A BOX WITH THE NEEDS OF THE COLOMBIA BON AND WITH NASA EARTH SCIENCE DATA WE WILL INCORPORATE FLEXIBILITY TO ADDRESS THE NEEDS OF DIVERSE USERS AT MULTIPLE SCALES FROM NATIONAL TO GLOBAL AND TO WORK WITH REMOTELY SENSED DATA FROM ANY SPACE AGENCY IN GEO
