  • One replicated, controlled study in the USA found that planting buffer strips along streams did not increase amphibian abundance, numbers of species, or the ratio of adults to tadpoles.


Supporting evidence from individual studies


A replicated, controlled study in 2006–2009 of channelized agricultural streams in Ohio, USA (Smiley, King & Fausey 2011) found that planting buffer strips along streams had no significant effect on amphibian communities. There was no significant difference in species richness, diversity, abundance or ratio of adult frogs to tadpoles between sites with and without buffer strips. Amphibians were monitored in three streams with planted non-woody buffer strips (<15 m) and three without. Two 125 m long sections were established along each stream (average 743 m apart). Six permanent transects (25 m apart) were sampled along each section in spring, summer and autumn each year.
