Use prescribed burning
A site comparison study in 2002–2003 in a shrubland site in Arizona, USA (Pasch & Koprowski 2011) found that prescribed burning resulted in smaller individual home ranges and shorter daily movements for Mexican fox squirrels Sciurus nayaritensis chiricahuae than did fire suppression. The average home range in prescribed burning areas (2.9 ha) was smaller than in fire suppression areas (6.6 ha). Average daily movements were lower in prescribed burning areas (212 m) than in fire suppression areas (336 m). In a 5,000-ha protected area, prescribed burning was initiated in 1976. In 1980–2001, there were 33 fires, over 260 ha total extent. Forty-three squirrels were live-trapped. Adults were radio-collared and data were analysed from 11 male and nine females, with ≥30 location fixes per season, from May 2002 to September 2003. Daily movements were measured by locating animals three times from 05:00 h to 11:00 h.
