Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Manage grazing regime One replicated, controlled study in the UK found that grazed plots did not have higher abundance of natterjack toads than ungrazed plots and had lower abundance of common toads. Five studies (including four replicated studies) in Denmark, Estonia and the UK found that habitat management that included reintroduction of grazing increased green toad populations, maintained or increased natterjack toad populations and maintained common toad populations. One before-and-after study in the USA found that the decline in amphibian species was similar under traditional season-long or intensive-early cattle stocking.

One study in the UK found that despite assisting toads across roads during breeding migrations, at 7% of sites over 500 toads were still killed on roads. Five studies in Germany, the UK and Italy found that large numbers of amphibians were moved across roads by patrols. Numbers ranged from 7,532 toads moved before and after breeding to half a million moved during breeding migrations annually. In the UK, there were over 400 patrols and 71 patrols spent an average of 90 person-hours moving toads and had been active for up to 10 years.

One study in South Africa found that the number of permits issued for scientific and educational use of amphibians increased from 1987 to 1990.
