Reptilewatch JE

What is Reptilewatch JE?

Reptilewatch JE is a project that aims to gather sightings of Jersey’s reptiles to help assess their conservation status, distribution and habitat requirements.

By taking part in the Reptilewatch scheme, you will be contributing important data to inform the ongoing conservation of reptiles in Jersey.

How can you help?

There are opportunities for everyone to get involved. Depending on your interest, available time and experience you can currently get involved in the following three ways.

Level 1

Spend 30 minutes looking for reptiles and send us your results here. No experience or training is required but we recommend that you attend the annual training event (details below) to find out more about the survey and Jersey's reptiles.

Level 2 - Wall Lizard

Carry out 6 visual surveys for Wall Lizards, each taking 30 minutes. No previous experience is needed but you will need to attend a training event (details below).

Level 2 - Widespread

Carry out 6 visual surveys along a transect, each taking 1-2 hours. No previous experience is needed but you will need to attend a training event (details below).

All surveys take place between March and October.


An in-person training event is held at the start of the Reptilewatch survey season each year.

The 2024 training event will take place on Saturday 16th March 2024 from 10am at the Frances Le Sueur Centre, St Ouen.

We are delighted that Dr Rob Ward will be joining us to share his knowledge of Jersey's rarest reptile, the Grass Snake.

This free event is open everyone although we ask that anyone wishing to attend reserves a place via Eventbrite.

Jersey’s Reptiles

Western Green Lizard Lacerta bilineata

Male Western Green Lizards are bright green with a bright blue throat, while females have the same bright green colouration but with a duller throat.

They are typically sighted on warm sunny days in coastal grassland, heathland and dune habitats.

Wall Lizard Podarcis muralis

Wall Lizards are typically brown to grey in colour.

They are most commonly found in the north and east of the island, favouring fortifications and dry stone walls.

The largest population is located in the area of Mont Orgueil Castle.

Slow worm Anguis fragilis

Looking somewhat like a snake, these reptiles are actually legless lizards.

Slow Worms are grey, brown and copper in colour and grow up to 50cm in length. Females can be identified by the presence of a black strip running along the side of the body. The Juveniles of both sexes are gold with brown bellies and sides.  

Slow worms can be found in a variety of habitats across the Island but they are rarely seen out in the open, preferring to spend their time underground or in amongst low-level vegetation and leaf litter.

Like many lizards they have the ability to shed their tails to escape predators. 

Grass Snake Natrix helvetica

This non-venomous snake is Jersey’s rarest and most elusive reptile.

Grass Snakes are olive green or brown with a yellow collar behind the neck, and can grow up to a metre long.

Grass Snakes can be found in grassland, wetland, dune and heathland habitats. They are typically sighted in the west of the island, with Noirmont, Ouaisne, St Ouen's Bay and La Moye Golf Course being particularly important locations for them.
