Use prescribed burning on pine forests
A replicated experiment in 1999-2001 in 13 longleaf pine forest plots within Conecuh National Forest, Alabama, USA (Tucker et al. 2006), found that a significantly lower proportion of Bachman's sparrow territories in compartments burned four years previously (20% of 20) successfully produced young than those in compartments burned less than three years previously (52% of 50). In addition, a higher proportion of male sparrows remained unpaired in compartments burned four years previously compared to those in more recently burned plots (50% of 20 males in plots burned four years before remain unpaired vs. 28% of 50 in more recently burned areas). There was no significant difference between growing or dormant season burn plots. Daily survival rates were similar in compartments burned 4-years previously (93%) and those burned more recently (94%), and those burned during the growing or dormant season (89% and 95% respectively).
