Use prescribed burning on grasslands
A replicated, controlled trial in March-May 1993-1994 on Matagorda Island, Texas, USA (Hull et al. 1997), found few differences in spring bird abundance in cordgrass Spartina-dune paspalum Paspalum monostachyum grassland subject to summer compared to winter burns. Six 122 ha plots were established each year: two unburned; two burned late August (1992-1993); and two in January (1993-1994). Wrens (Troglodytidae) were consistently most abundant in unburned plots (21-28 birds/40 ha in unburned areas vs. 2-3 for summer burn and 1 for winter burn); 18-22 months after burning wren abundance increased but was still less than within unburned plots. Sparrows (Emberizinae) were most abundant on burn plots both 6-10 months (unburned: 3-8 birds/40 ha vs. summer burn: 16-19; winter burn: 11-16) and 18-22 months post-burn.
