摘要: Riparian forest communities in the southwestern United States were historically structured by a disturbance regime of annual flooding. In recent decades, however, frequency flooding has decreased and wildfires increased. forests provide important breeding habitat for large variety bird species, effects this altered on birds their is largely unknown. To evaluate high-intensity spring summer wildfire quality Middle Rio Grande valley, we measured vegetation structure composition, avian nest use, success at 4 unburned plots over 3-year period. We use boxes located riparian recently burned wildfire. Recent ( 7 yr after fire) plot more closely resembled its paired than did plots. Ash-throated flycatchers (Myiarchus cinerascens) Bewick's wrens (Thryomanes bewickii; hereafter, wrens, respectively) used most A model selection procedure applied to logistic regressions showed that box was positively associated with wildfire, although as well. Wrens preferential sites close proximity vegetative cover. Growth rates, feeding fledging mass similar rates slower plots, while similar. Nest predation varied between years, higher not directly influenced Model increased grass cover, an indicator openness, distance edge. Recovery dense appears maintaining populations whereas ash-throated less sensitive composition postfire succession. Postfire management maintains strips would enhance nesting density these cavity-nesting zones.
