Twelve publications were found in an online search of freely accessible
best practice guidelines (Table 1 ). These guidelines are from a
range of countries, with the exception of “Wildlife and Traffic: A
European Handbook for Identifying Conflicts and Designing Solutions”
which covers Europe as a whole. The earliest guideline was published in
2001 and the latest in 2022, with more frequent publications become
available from 2015 onwards. There is also a mixture of how these
guidelines recommend fencing for reptiles and amphibians (Table
2 ). Two guidelines (IENE and the Wildlife Institute of India) provide
recommendations for reptiles and amphibians as a whole, without
subsequently breaking them down into genus. Two guidelines provide
recommendations for reptiles and amphibians as a whole and then provide
extra information for frogs (Vic Roads) and for frogs and freshwater
turtles (Queensland Department of Transport and Main Roads). The Western
Transport Institute, Montana State University provides the most
comprehensive list of recommendations by detailing specifications for
each genus rather than reptiles and amphibians as a whole.
Table 1. A summary of the general recommendations, materials, fence
depth below ground and anti-dig and anti-cimb lip provided in the twelve
best practice guidelines in this review.
