  1. Deconstructing Your Action A Strategy for Analyzing Impacts on Bird Populations

  2. Effects Analysis A thorough analysis of an action’s impacts on the species and its resources is an essential component of the coordination process to reduce impacts to migratory birds ?

  3. Analyzing Effects Deconstruct the Action • Break the proposed action into its separate components Exposure • Identify which birds and resources will be affected by produced stressors Response • Understand the consequences to birds from stressor exposure

  4. Goal and Objective Goal: Determine whether a species and/or its resources will be exposed to stressors produced by project activities Objective: Link cause and effect relationships between an activity and bird demography

  5. BENEFITS • Raise awareness to how actions affect birds • Provide transparent and logical step-wise process • Identify appropriate conservation measures • Optimizes the allocation of staff and funding

  6. Deconstructing the Action • Identify PROJECT TYPE • Identify ALL ACTIVITIES associated with the Project • Identify STRESSORS produced by ALL activities

  7. Understanding Exposure Bird Conservation Needs • All species have three main conservation needs • Breeding • Sheltering • Feeding • Specific resources are required to meet these conservation needs

  8. Resources • Appropriate Vegetation Structure • Nest sites • Food • Shelter from weather • Access to food for adults and young • “Healthy Space” (natural balance) • Predators • Parasites • Competitors • Disease • Other Disturbances

  9. Understanding Response How do birds and/or their resources respond when exposed to a stressor? • Consider all life stages • Are there reported responses • scientific and commercial information • If no information, use the precautionary principle to determine the most likely response

  10. Increasing Severity Behavioral Sub-Lethal Lethal Alarm Startle Avoidance Abandonment Displacement Death No Response Increased respiration <10% probability of death Altered behavioral displays Reduced Feeding Success Reduced Growth Rates Reduced Fecundity Reproductive Failure 10-20% probability of death 20-40% probability of death 40-60% probability of death Delayed Age at Sexual Maturity Depressed autoimmune responses Response Continuum

  11. THREAT EFFECTS IMPACTS FOCUS ON THE IMPACTS
