The lesser prairie-chicken (Tympanuchus pallidicinctus) has seen significant declines in its range and population since the early 1900s. Research in Kansas has shown that Conservation Reserve Program (CRP) grasslands are used by lesser prairie-chickens for breeding, nesting, and brood rearing. Lesser prairie-chicken use of CRP grasslands in New Mexico has not been well documented and there is disagreement as to its importance in their life history. In light of this, I set out with the following objectives: 1) estimate breeding season survival and determine cause specific mortality of lesser prairie-chickens, 2) characterize lesser prairie-chicken seasonal space use relative to the distribution of CRP and native shinnery oak habitat, and 3) determine resource selection of vegetation characteristics by lesser prairie-chickens in eastern New Mexico. I captured and radio collared lesser prairie-chickens in the springs of 2014 and 2015 and monitored their movements throughout the breeding and non-breeding seasons. Breeding season male survival was almost double that of females in both years. Lesser prairie-chickens selected shinnery oak habitat in much higher proportion was available for both broad scale and resource selection analyses. My results indicate that in New Mexico: 1) lesser prairie-chicken survival is consistent with other stable populations and 2) shinnery oak habitat is being selected for more than CRP/grassland habitat by lesser prairie-chickens. Further habitat improvement efforts for this species in eastern New Mexico should consider switching focus from CRP and concentrate on conservation of native shinnery oak prairie.
