  • Joseph et al. (2009) extended the work of Metrick and Weitzman’s 1998 Noah’s Ark framework to include the probability that the management will succeed

Transcript

  • 1. Prioritizing Species and Actions Protocol Rita Dixon Idaho Department of Fish and Game
  • 2. Why prioritize?
  • 3. MOST critical needs
  • 4. Species with the GREATEST conservation need
  • 5. PRECLUDE the need to list
  • 6. http://teaming.com/sites/default/files/SWAP%20Best%20Practic es-110212-for%20website.pdf
  • 7. “Best Practice” method or technique, through experience and research, has consistently shown results superior to those achieved by other means
  • 8. Joseph, L. N., R. F. Maloney, and H. P. Possingham. 2009. Optimal allocation of resources among threatened species: a project prioritization protocol. Conservation Biology 23:328–338.
  • 9. Define objectives List biodiversity assets Weight assets List management projectsEstimate cost Predict the benefit Estimate likelihood of success State constraints Choose set of projects Joseph et al. 2009 Optimal Allocation
  • 10. (1) Define objectives e.g., To secure (over a period of 50 years) the greatest number of threatened species of value given a limited budget
  • 11. (2) List biodiversity assets of interest
  • 12. (3) Weight assets • Cultural significance • Social values • Economic importance • Evolutionary significance • Ecological function • Endemicity • Taxonomic distinctiveness • Climate Change Sensitivity • Threat status • Conservation responsibility of jurisdiction for species
  • 13. Levels of Endemism: State
  • 14. Levels of Endemism: Ecoregion
  • 15. Levels of Endemism: Region
  • 16. Taxonomic distinctiveness http://www.catalogueoflife.org/
  • 17. http://climatechangesensitivity.or g/
  • 18. Assess Risk • Range/Distribution • Abundance/Condition • Threats • Trends (short- & long- term)
  • 19. Threat Status • SH Possibly Extirpated • S1 Critically Imperiled • S2 Imperiled • S3 Vulnerable • S4 Apparently Secure • S5 Secure
  • 20. (4) List management projects • Choose an appropriate project for each species • Project is minimum set of all necessary actions for obtaining a reasonable (≥95%) probability of securing the species over 50 y • 4 compulsory components: – outcome monitoring – services and support – project management – infrastructure • at least one optional intervention (e.g., captive breeding, translocation, pest animal control, weed control, legal actions, education) • Specify precise location, intensity, and duration of management for each action
  • 21. (5) Calculate the cost of each project • Total estimated cost over a 10-year period (i.e., SWAP revision period)
  • 22. (6) Predict the benefit to assets
  • 23. (7) Estimate likelihood of success • Mi = probability that each project, i, could be implemented successfully • Ni = probability that, if implemented successfully, it would be reasonably (≥95%) successful in securing the species • Total probability of success of each project, Si, = MiNi
  • 24. (8) State constraints • Identify constraints on the projects and the total budget • Primary constraint is total budget available
  • 25. (9) Rank projects
