Replant vegetation Amphibian Conservation

A before-and-after study in 1999–2003 of retired agricultural land in California, USA (Uptain et al. 2005) found that upland habitat restored by seeding and transplanting native plant species was colonized by western toads Bufo boreas. The species was recorded annually from 2000 and was the only amphibian observed. In 1999, native plants were introduced to 20 plots (4 ha) in randomized blocks by either seeding or transplanting, with or without surface contouring. Visual encounter surveys (circular plots and transects) and artificial coverboard surveys (4/plot) were undertaken four times annually.
