An initial walkover survey will identify whether a site has suitable habitat to support reptiles. Secondary reptile surveys may be require which are undertaken during the reptile activity season. Surveys may consist of both a visual search of the habitat for basking reptiles in the open and a search beneath artificial and natural refugia.
Artificial refugia are frequently used in surveys, being the most reliable method for assessing reptile presence or absence on a site. The refugee are laid out in habitats considered suitable for reptiles and after a period of approximately eight weeks, they are checked for the presence of reptiles basking on or under them.
The optimum months for reptile surveys are April-May and September. Typically 5-7 visits in suitable weather are sufficient to provide reptile presence or absence from a site. Use the reptile survey and mitigation calendar above to help plan your works schedule.
