Manage grazing regime
A replicated, controlled study in 1992–1995 of natterjack toad Bufo calamita terrestrial habitat in southern England, UK (Denton & Beebee 1996) found that natterjacks did not use grazed plots more than ungrazed plots. There was no significant difference between average numbers in grazed and ungrazed plots for toadlets (13 vs 13) or adults (5 vs 5). Total common toad Bufo bufo numbers were lower in grazed compared to ungrazed plots and surroundings (1 vs 11). Four plots (20 x 20 m) of each of four habitats were established: grassy clearfell, sandy clearfell, heath and moss habitat. Two plots of each were grazed in May–September by highland cattle (1 adult/3 ha). Captive-reared natterjack toadlets were released onto each square in summer, 75 in 1992 and 20 in 1993. Toads were monitored twice monthly in April–September 1992–1995.
