At least three of the six native reptiles occur in Balcombe. The Society conducts seasonal reptile surveys to collect valuable data and better understand local populations. The Society undertakes two types of reptile surveys:

Reptile refugia surveys

Refugia surveys involve using artificial cover objects, such as roofing felt, along suitable habitat margins and sunny banks. Reptiles gather under these refugia mats as they regulate their body temperature with their surroundings. Surveys deploy the mats from April until September and check them once a month, during suitable morning times. Species are identified, counted, and recorded with minimal disturbance.

Direct observation surveys

Visual observation surveys include walking predetermined transects along hedgerows, woodland edges, and rough grassland during bright, warm weather. Surveyors scan natural basking spots, such as log piles and grass tussocks, and use binoculars to identify and record individuals. This provides valuable complementary data for species less inclined to use artificial refugia and helps map active foraging corridors.
