AbstractBotanical content of the blacktailed jackrabbit (Lepus californicus) diets and relative preference indices for various plant species were evaluated. The study was conducted in southern New Mexico in June, August and October, on six vegetation types: mesquite-grass type, black grama type, snakeweed type, mixed-shrub grass type, creosotebush type and tarbush type.
