Abstract
We compared pellet-group counts and radio-telemetry triangulation methods for determining the relative habitat use by adult female mule deer (Odocoileus hemionus) on summer range in the central Sierra Nevada Mountains, California [USA]. Although a Chi-square goodness-of-fit test of observed and expected frequencies was significant, only 1 of 10 habitats was ranked out of order. Pellet-group counts are useful in ranking relative use of habitats, but may not be reliable for ranking habitats that receive similar levels of use.
