AbstractA study of the response of rodent populations to poisoning was conducted on the desert grassland range of southern New Mexico. Strychnine and 1080-treated grain was distributed on a 12-section grid, each section receiving one poison in one of six distributional patterns. The 1080 poison, scattered in a 100- X 200-foot grid, was the most economical (3.5 cents per acre), and the 1080 poison gave better controls at both the 1-month and 1-year checks. The densities of the five major species within the poison area and check areas fluctuated independently, giving a decided change in the species population from year to year. Though the species composition changed, the rodent biomass remained constant on the unpoisoned area. On the poisoned area, 2 years after the poisoning, the total rodent biomass was only slightly over one-half the biomass of the uncontrolled population.
