Div Mon Update

  1. 1. FWP/NHP Multiple Species Monitoring Effort
  2. 2. History Kalispell Missoula Great Falls Havre Lewistown Sidney Helena Miles City Anaconda Butte Billings Bozeman Laurel Livingston Sampling Locations • FWP Diversity Monitoring Project (T-020) • NHP Statewide Amphibian Surveys • FWP/NHP Acoustic Bat Surveys • Other
  3. 3. 3-Year Goals (2008-2010) • Document occurrence of previously neglected faunal groups in Montana • Estimate occupancy with reasonable precision while accounting for imperfect detection • Develop a statewide monitoring framework for several faunal groups that is rigorous, repeatable, documented, and acceptable to a wide variety of potential participants (USFS, BLM, USFWS, etc.)
  4. 4. 2008 Field Season Goals • Hone field methodology for reliable detection of bats (acoustics) and reptiles • Gather more baseline occupancy and detection estimates – These will help inform future sample allocation • Thorough sampling in two ecoregions along the Highline (mainly due to logistics) • Coordinator + three crews of two
  5. 5. Focal Faunal Groups • Reptiles • Volant Mammals • Small Mammals • Amphibians • Birds
  6. 6. Parameters to be Estimated • Proportion of Area Occupied (PAO) or Ψ • Probability of Detection or p • Ways to estimate these parameters – Design based estimates – Model based estimates • We have designed a sampling scheme that accounts for potential confounding factors that may affect our estimate
  7. 7. New Sampling Methodology • Stratified Random Sampling – Bailey’s Ecoregions (Or alternative) – Landcover class • Spatially Balanced Design – GRTS sampling – Allows for oversample (in case of landowner denial) • Targeted Sampling Separately (Adapted Sampling)
