RESEARCH/MONITORING NEEDS (source(s) of needs)

Monitoring

  • Priority monitoring action – Conduct early spring desert surveys (PIF Monitoring Needs doc)
  • Second priority monitoring action – Conduct new winter surveys (PIF Monitoring Needs doc)
  • High priority candidate for rapid status assessment (PIF Monitoring Needs doc)
  • Supplemental BETH Surveys - Habitat specific monitoring of Chihuahuan Desert Shrub species in New Mexico including BETH ( New Mexico ); Determine population status of BETH in New Mexico ( New Mexico )

Habitat Needs/Ecology/Life History

  • Determine ecology of BETH in New Mexico ( New Mexico )

Effects of Human Development/Disturbance

  • Need quantitative information on the effects of human activities on BETH (BNA)
