Effect of seed size on removal by rodents

by: William G. Standley
ABSTRACT: Plots located in southeastern Arizona were seeded with small and large grass seeds. After 3 days, virtually all large seeds were removed by rodents, while small seeds were still present 36 days after planting. Thus, managers may increase seed survival in this area, without removing rodents, by reseeding with small seeds rather than large seeds.
