Native Snakes of Britain: Species and Habitat

Britain is home to three native species of snakes. The adder is the only venomous snake in Britain, and it's found in a variety of habitats, including heathland, moorland, and rocky outcrops.

The adder is a relatively small snake, typically growing to around 60-70 cm in length. It's a solitary creature, only coming together with others of its kind to mate.

The grass snake is the longest native snake in Britain, with some individuals reaching lengths of over 1.5 meters. It's a common sight in wetlands, grasslands, and other areas with abundant vegetation.

The smooth snake is a rare and endangered species, found in southern England, particularly in heathland and sandy soils.

The UK is home to three species of native British snakes: the adder, grass snake, and smooth snake. These snakes are quite distinct from one another, with unique characteristics that make them easy to identify.

The adder, for example, has a grey colour with red eyes and a distinct zig-zag pattern on its back. The grass snake, on the other hand, is greenish in colour with dark markings on the sides.

If you're interested in learning more about these snakes, here's a brief rundown of their characteristics:

The barred grass snake, also known as Natrix helvetica, is a distinct species from the grass snake, growing up to 1.8m in length.

This species was previously considered a subspecies of the grass snake but was reclassified in 2017.

The barred grass snake has a unique olive-green to brown body with black markings on its flanks, and a yellow and black collar marking.

Female grass snakes, which is another name for the barred grass snake, lay eggs in warm areas during the summer months.

These eggs then hatch in the late summer months, completing the life cycle of this species.

In England, you'll find three species of native British snakes. The UK is home to these slithery creatures, including the adder, grass snake, and smooth snake.

The adder is easily recognizable due to its grey color and red eyes. Its back features a distinct zig-zag pattern.

The grass snake is greenish in color and has dark markings on its sides. Its slender body and rounded pupils are also notable features.

The smooth snake is grey and has a slender body, making it easy to identify. Its round pupils are another distinctive characteristic.

The slow worm, actually a legless lizard, is often mistaken for a snake. It has golden-grey skin and is a unique addition to the UK's native reptile population.

Here's a quick rundown of the native British snakes and the slow worm:

If you're lucky enough to spot a native British snake in your garden or the wild, remember to leave them undisturbed.

If you see a snake that's sick or injured, it's a good idea to contact the relevant authorities for assistance.

Leaving snakes alone is crucial, as they play a vital role in maintaining a balanced ecosystem in your garden and the wider environment.

If you find snakeskin, you may be able to work out which species of snake it is by looking carefully at the scale patterns. This can be a useful skill to have, especially if you live in an area where snakes are present.

To identify British snakes, you can use a guide that shows the different species and their characteristics. For example, the Wildlife Trusts website has a guide that can help you identify the different snakes you might encounter in your garden or while out walking.

The adder, for instance, has a distinctive pattern of zig-zag markings on its back, which can be a key identifying feature. The smooth snake, on the other hand, has smooth scales that are not overlapping, giving it a distinctive appearance.

If you're trying to identify a snake, it's a good idea to look at the pattern of the scales, as well as the shape of the head and the color of the body. By considering these different characteristics, you can narrow down the possibilities and increase your chances of identifying the snake correctly.

The grass snake, for example, has a distinctive pattern of dark blotches on its back, which can be a key identifying feature. By looking at these patterns and characteristics, you can get a better sense of which snake you might be looking at.

Slow worms are often mistaken for snakes, but they're actually a type of legless lizard.

They can live up to 30 years in the wild and considerably longer in captivity.

One of the most interesting things about slow worms is their ability to shed their tails as a defence mechanism against predators.

Slow worms give birth to live young, which is a unique characteristic among reptiles.

It's worth noting that slow worms are protected under The Wildlife and Countryside Act 1981, which means it's an offence to intentionally harm or remove them from the wild.

Here are the 4 species of native reptiles found in the UK:

Slow worms are often found at the bottom of compost heaps, where they feed on slugs and worms.

They live in burrows, under rocks and logs, particularly in heathland, woodland edges, and long grass areas with an abundance of invertebrates.

You can spot slow worms on the South West Coast Path, where I've personally seen many specimens.

Their activity is mostly limited to twilight and dusk hours, so it's essential to keep your cats indoors at night to protect them from slow worms' main predators.

During spring and summer, you might catch a glimpse of slow worms basking in the sun, but they typically hibernate between October and March.

Slow worms can be found across Great Britain, excluding Northern Ireland.

Adders are the only venomous native snakes in the UK and the only vipers found in the British Isles. They're relatively small, growing to an average length of 60cm.

Male and female adders can be distinguished by their appearance, with males being light grey and females being light or copper brown. Both have a dark zig-zag running down their back, and black adders can also be found, which are usually female.

Adders give birth to live young, a process called ovoviviparity, in August or September after mating in the spring.

The adder is most common in the south and south west of the UK, and it's not an aggressive species, so you don't have to worry about it attacking you. It's actually quite placid.

Here are some key facts about adder habitats:

If you're unfortunate enough to get bitten by an adder, don't panic and don't try to treat it yourself. Take off any jewellery and try to keep the bite area as still as possible to prevent the venom spreading through the body, then go straight to the local hospital.
