Use prescribed burning on shrublands
A replicated, controlled study in montane shrubland in Rocky Mountain National Park, Colorado, USA, (Jehle et al. 2006) found that green-tailed towhee Pipilo chlorurus occurrence and nesting density was significantly lower for 3-5 years after burning in four areas of subject to prescribed burning (0.05-0.30 birds/ha) compared with three unburned sites (0.60-1.95 birds/ha). Two sites, Deer Ridge Low (55 ha) and Deer Ridge High (80 ha), were burned in 1998 and 1999 respectively, with towhee density estimated in June 2002-2003. Of 179 nests found, only 14 (8%) were at burned sites, and were within remnant patches of live shrubs (in areas where burn severity had been lower).
