New Mexico

Cougar status in a human dominated landscape

basics
Basics
  • Cougar Season: Oct. 1- Mar. 31
  • Year around on private lands and BHS areas
  • Bag is 1 adult, 2 on BHS areas, and special mgmt. areas
  • Avg. harvest is +/- 200 animals
  • Avg. harvest increases with time, non-resident harvest increases with time
  • Hound use is allowed and accounts for 90% of harvest
  • Long term avg. of 40% female in harvest
management history
Management History
  • 1867: $5.00 bounty
  • 1923-70: Bounty suspended, cougar unprotected.
  • 1971: Protected, hunting in SW Only, bag 1
  • 1972-1978: Seasons increasingly liberal
  • 1979-83: 11 month season, bag 2.
  • 1984: 3 month season, bag 1.
  • 1985-99: 4 month season, bag 1
  • 2001-2002: 6 month season, year around season in BHS areas, bag 1
  • 2002-2007: Year long in BHS areas, bag 2, year around season on private property
  • 2007-… : Dual harvest limit, sport and total sustainable mortality, population model and management driven
management concerns
Management Concerns
  • Total mortality
  • Sustainable mortality (depredations, BHS removals, roadkill, private land harvest, preventative control, etc.)
  • Sport harvest (private land harvest not included in sport harvest)
  • Management objectives by region (BHS, wild ungulate protection, livestock depredation issues, etc.)
  • Female harvest, particularly older females
how to fix it
How to Fix it?
  • Create a new habitat model
  • Try and include all variables
  • Do the math and see what you get
  • Does it make sense?
  • If it makes sense try to apply it for some period of time
  • And you get…
model habitat components
Model Habitat Components
  • Super Core = > 2200 k² w/good prey density in large patches w/low road density (sources)
  • Core = 2200-1000 k² patches w/low road density (sources and dispersal)
  • Minimum patch = 100-1000 k² patches (dispersal and minimal sources)
  • Dispersal = 10-100 k² patches (dispersal only)
faults with model
Faults with Model
  • Based on density estimates
  • Based on assumptions of prey usage (density estimates)
  • Based on assumptions of how much habitat a given cat uses (density estimates)
  • Based on what a cat would do given the choice of what to do if it does what we assume it would do if we were it…
current research needs
Current Research & Needs
  • Female removal = no resident males
  • Habitat use and connectivity
  • Genetic linkages
  • Prey switching and/or subsidized predation
  • Source/sink dynamics ($, grad student, ??)
  • And yet again, how do you count freakin’ lions?
