Reptiles play an important role in the function of ecosystems, whether as predators controlling prey populations, or as a source of prey for both birds and mammals. There are eleven species of reptile in the UK, of which six are native and all are protected under UK legislation, with the extremely rare smooth snake and sand lizard protected by additional EU legislation.
At this time of year reptiles are emerging from hibernation and ecologists are beginning to prepare for the survey season. Reptiles are active between March and October and surveys are carried out in April, May and September when the reptiles are at their most visible. In the main summer months (June – August) reptiles tend to bask less and are unlikely to use any artificial refugia, therefore surveys are not undertaken during this time .
The most common survey methods for reptiles include searching for basking animals on banks, piles of wood and edges of woodland, or laying out artificial refuges like corrugated iron sheets and carpet tiles or roofing felt, which are bedded down well into the vegetation. A wide range of reptile surveying equipment is available to buy on the NHBS website. For any advice please contact our Wildlife Equipment Specialist team who would be happy to help.
Corrugated reptile refugia are often used in reptile surveys as they absorb heat and provide shelter from predators, making them an ideal basking spot, especially for slow worms or smooth snakes. The refugia are made from corrugated roofing material (bitumen soaked organic fibres) which is lightweight and waterproof. The material is free from asbestos,non-toxic and is both waterproof and long lasting. The sheets are 2.6mm thick and measure either 500mm x 500mm or 500mm x 1000mm, both with a corrugation depth of 40mm.
As with the corrugated refugia above, felt squares also create favourable conditions beneath them for reptiles and are commonly used for surveys, as they are light and will roll up for transport. These tiles are made from bitumen felt and are available in two sizes: 50 x 50cm or 100 x 50cm.
A snake hook is useful for catching and managing snakes for inspection or translocation. There are two snake hooks available, both made from aluminium which provides a tool which is both strong and lightweight. The standard snake hook comes in two sizes: 100cm or 130cm and has a wooden handle. The telescopic snake hook can be extended from 95cm to a total length of 140cm and the end of the handle has a comfortable rubber grip.
Snake tongs are also useful for handling snakes for inspection or translocation. There are two lengths of tongs available: 92cm or 122cm. They are made from an anodized aluminum shaft with a pistol grip handle to provide a lightweight yet strong tool enabling maximum holding pressure with minimal risk to the handler or the snake.
Snake handling gloves are designed to give you protection when handling snakes and to protect you when conducting snake surveys. The gloves are made from leather to minimise the risk of injury from bites and will also help mask your scent. They are available separately for the left or right hand.
N.B. These gloves are not suitable for handling venomous species!
Native reptile species in the UK range on average from 5 to 100g. Pesola scales are universally acclaimed precision scales which are reliable and durable. The Light-Line range features a transparent tube for panoramic reading and a long, clear double display with coloured marker ring. They are adjusted by hand with a guaranteed accuracy of +/- 0.3% the precision spring is made of corrosion-free, fatigue-resistant alloy, and the scales are impervious to humidity.
A note on licensing
Please note that reptiles in the UK are protected by law. Any reptile survey work must be undertaken by a licensed ecologist. Different levels of license are required for different survey and mitigation methods. For more information, please visit: https://www.gov.uk/guidance/reptiles-protection-surveys-and-licences
