  3. Guidelines for Avian Monitoring Goal 1: Integrate monitoring into bird management and conservation practices. Goal 2: Coordinate monitoring programs among organizations and integrate them across spatial scales. Goal 3: Increase the value of monitoring information by improving statistical design. Goal 4: Maintain bird population monitoring data in modern data management systems. http://www.nabci-us.org/aboutnabci/monitoringreportfinal0307.pdf

  4. Our Objectives • Provide a design framework to integrate bird monitoring efforts • Precisely estimate distribution, density, site occupancy, population trends and species richness • Provide habitat association data relevant to landscape changes • Maintain a high-quality database, accessible online • Create decision support tools to help guide conservation efforts

  5. Bird Conservation Regions

  6. CurrentMonitoring Programs All lands in BCR 17 All lands in CO, WY and MT Portions of 9 additional states All BLM lands in: CO, WY, MT, ND, SD All USFS lands in Regions 1 & 2 (CO, WY, NE, KS, SD, ND, ID, MT) 3 National Forests in Region 3 (Kaibab, Coconino, Prescott)

  7. 2010 Landbird Monitoring

  8. Current Partnerships • Colorado Division of Wildlife • Wyoming Game and Fish Department • Montana Fish, Wildlife and Parks • South Dakota Game, Fish and Parks • USFS: 27 NationalForests, 9 National Grasslands, 4 regions, 12 states • BLM in 5 states • National Park Service • …(continued)

  9. Current Partnerships (cont.) • Northern Great Plains Joint Venture • Audubon Wyoming • Wyoming Natural Diversity Database • Montana Natural Heritage Program • Idaho Bird Observatory • Avian Science Center • Great Plains Landscape Conservation Cooperative

  10. Sampling Design and Methods Sampling Frame Sampling Units Sample Selection Sample Allocation (effort) Sampling Methods

  11. Sampling Frame: BCRs

  12. Sampling Units 1 km2 cell Step 1: Overlay grid on sampling frame Step 2: Attribute each cell with pertinent data (unique ID, spatial location, land ownership, elevation, soil type, …)

  13. Sample Selection Spatially Balanced: Generalized Random Tessellation Stratification (GRTS) • Ensures a spatially balanced distribution of samples within each stratum • ~ Random • Analyses can incorporate spatial information in estimation of sampling variance

  14. Sample Allocation Minimum of 2 samples required/stratum Recommend 10 Determined by funding partners May vary annually

  15. Example: Base Sample in BCR 18

  16. Additional Samples in Colorado

  17. Additional Samples - Comanche NG

  18. Sampling methods • 16 points per cell • 250 m spacing • 125 m from edge • 6 minute point count • 1 minute intervals • Record distance to each bird seen or heard • Record species and sex for each observation

  19. Questions? Jeff Jones

  20. GPLCC Monitoring Grid Objectives • Create a standardized monitoring grid • USNG or MGRS • Develop long term bird monitoring strata for GPLCC • Grid attributes • Select samples • Spatially balanced sampling • GRTS function in R

  21. Great Plains LCC Landscape Conservation Cooperatives (LCCs) • Science-based Partnerships • Help guide and coordinate conservation efforts at regional levels • Great Plains LCC consists of BCRs 18 & 19

  22. GPLCC Monitoring Grid • The need for a monitoring framework at the regional level • Spatial context for statistical inferences and predictions • USNG Monitoring Grid • Biologists can use grid to monitor a variety of taxa at multiple scales • Key grid elements: spatial extent, datum/projection, scalability, standards

  23. US National Grid (USNG) • USNG identified as a potential standard for monitoring populations at regional levels • Developed by FGDC for emergency response coordination • 1-km square grid cells • Contains key elements for a proper monitoring grid (national coverage, commonly used datum/projection, scalable)

  24. USNG (cont.) • Based on the NAD 83 geographic coordinate system • Universal Transverse Mercator (UTM) projection • Similar to the Military Grid Reference System (MGRS) • MGRS uses WGS 84 datum • Covers the entire United States • MGRS worldwide coverage

  25. USNG Scalability • The unique addressing system for the USNG allows scalability from 100,000-km square to 1-m square. • Labeling system • UTM Zone Designation. • 100,000-meter square designation • USNG: unique grid coordinates for a 1-km square • Eastings/Northings • Each 1-kilometer square grid cell has a spatial address (e.g. 13TGF3437) • Grid zone designator (13T) • 100,000-meter square identification (GF) • Unique grid coordinates (3437)/Eastings (34), Northings (37)

  26. USNG Issues • Zipper effect: Cells along UTM zone junctions are smaller than 1-km square. • Only affects 0.33% of grid cells in GPLCC • Causes sampling problems; may bias estimates • Many possible solutions • Remove zipper cells • Merge zipper cells to adjacent cells • Overlap zone junction cells

  27. Zipper Effect

  28. Zipper Effect Solution: Merge Cells • Merged cells smaller than 0.95-km square into their adjacent cells • Equal probability of being selected • No gaps or overlap • If selected for sampling, a 1-km square will be randomly placed inside cell

  29. Grid Attribution • We used GIS to attribute GPLCC grid • NRCS Soils • NRCS Major Land Resource Areas (ecoregions) • Federally owned or managed lands • National Hydrography Dataset (NHD) Strahler order • USFS proclaimed boundaries • Nebraska: Biologically Unique Landscapes • Priority Conservation Areas

  30. Final Product • ArcGISgeodatabase • Grid datasets established by UTM zone, State, and BCR • Location of cell centroid • Naming convention: “STATE_USNG_UTMxx_BCRxx” Example: CO_USNG_UTM13_BCR18

  31. Benefits of a standardized grid • Same starting point • Spatial continuity across different projects • Decrease project costs, necessary labor, and duplicate sampling efforts • No need to create multiple grids for multiple projects

  32. Benefits (Cont.) • Should improve partnership coordination at the landscape and local level to accomplish shared conservation goals (ABC and NBII) • Can also be used for other monitoring programs • FLAM surveys across western US • Bat surveys USFS • Grouse Surveys CDOW

  33. Stratification Development Stratification should be defined by areas to which we want to make inferences Strata are based on fixed attributes • Federal/state land ownership • Elevation, latitude, soil type, ecoregion All vegetation types available for sampling Flexible: Each state within the BCR and each BCR within a state can be stratified differently (depending on local needs)

  34. GPLCC Stratification Strata based on GIS layers: NRCS Ecoregions Soils Federal Land Ownership Rivers (Strahler order) Biologically Unique Landscapes (NE) Priority Conservation Areas
