  1. Use prescribed fire or modifications to burning regime in grassland

    A site comparison study in 2006 of cattle pasture in Corrientes, Argentina (Cano & Leynaud 2010) found that amphibian diversity, species richness and abundance was significantly lower following annual prescribed fires. Species richness and abundance was significantly lower with annual prescribed fire with or without grazing (richness: 7–9; abundance: 17–23) compared to sites that had not been burned for three or 12 years (richness: 10; abundance: 46–49). Diversity was significantly lower at the site with annual prescribed fire and grazing (1.3 vs 1.9–2.1). Species composition differed most between the unburned site and that with annual prescribed fire and grazing (Sorensen’s similarity index = 0.58). Only two of 12 species showed significant differences between treatments. The four historic treatments (≥ 400 ha) were: annual prescribed fire (August–September) without or with grazing (3 ha/cattle unit), three years since a prescribed fire, and no fire or grazing for 12 years. Monitoring was undertaken using drift-fencing with pitfall traps in January–April 2006.
