- Abstract
The article studies the effects of burn severity (BS) on avian communities. The study area was selected in the Jemez Mountains and adjacent Pajarito Plateau in New Mexico (NM). To quantify avian response patterns along a BS gradient, 49 random plots were sampled at the 17351-ha Cerro Grande Fire (2000) in NM. After-only densities were analyzed for 21 species using gradient analysis (GA). 71% of the species exhibited positive or neutral density responses to fire effects (FE) across all or portions of the severity gradient. Pre/post pair analysis was used to quantify density changes for 15 species using before-after comparisons. The study illustrates the significance of quantifying BS in studies of FE and suggests that after-only GA can be an efficient tool for quantifying FE.
