Boysag Point: A Relict Area on the North Rim of the Grand Canyon in Arizona

Abstract

Boysag Point, a 70-acre relatively ungrazed area in the pinon-juniper-sagebrush type, is described and compared to an adjacent grazed Mainland area. The Point had 88 species, the Mainland 38. Trees and shrubs made up 60% of the vegetation on the Point and 90% on the Mainland; Perennial grasses 36 and 6%, respectively; annual grasses and forbs 4% on each area. Average herbage production was 413 and 287 lb, respectively. Differences were attributed to grazing effects.
