You’ll spot two squirrel species in the UK, but only one is actually native. The Eurasian red squirrel is the local species; the grey squirrel came over from North America and now, honestly, you’ll see way more greys than reds in lots of places. This stuff matters because these two act differently and shape woodlands in their own ways.
Keep reading and you’ll find out where red squirrels still hang on, why their numbers crashed, and what folks are doing to help them bounce back. Knowing this makes it easier to spot each type and maybe even see how your local parks can help out.
Native Squirrel Species of the UK
Here’s where you figure out which squirrel is actually native, what it looks like, and the places you’re most likely to see one in the UK. The native red has its own food habits, nesting spots, and a few strongholds left.
Eurasian Red Squirrel Overview
The Eurasian red squirrel (Sciurus vulgaris) is the UK’s native squirrel. Most red squirrels stick to Scotland and a few islands, where populations seem to hold steady.
Across England, Wales, and parts of Ireland, grey squirrels have pushed reds out by competing and spreading diseases. It’s a tough break for the reds.
Red squirrels love tree seeds—think hazelnuts, acorns, and those little pine seeds from cones. Sometimes they’ll grab fungi, flowers, shoots, berries, or even the odd insect.
They stash food for winter and, if they remember, dig up their old stores. Breeding usually happens twice a year, so you might spot litters in spring or early summer.
If you see one, check for those tufted ears and their quick, almost frantic, leaps through the trees.
Physical Characteristics and Unique Features
Red squirrels look slimmer and smaller than greys. You’ll spot their reddish fur, but honestly, the shade can swing from deep red to brown.
In winter, their ears get these cute tufts, and their bushy tails help them balance and keep warm. Reds have flexible ankles that let them spin their feet backward to scurry down trees headfirst. Pretty wild, right?
This “double-jointed” trick lets them zip along trunks and branches. Their body and tail length gives them some serious leaping skills.
You can sometimes guess age and health by their coat and how they act. Young reds have softer, duller fur and aren’t as bold with big jumps. Adults move faster and guard their food stashes, especially when it’s breeding season.
Habitat and Distribution in the UK
Red squirrels go for conifer woodlands, especially Scots pine and mixed pine forests. They’ll also use some broadleaf woods if the food’s good.
You’ll find more reds in Scotland and on islands like Arran and Anglesey, plus a few nature reserves. Some conifer plantations help, but if the tree mix is off, there’s not enough food for everyone.
In most towns and cities, grey squirrels have taken over, so seeing a red there is rare. If you’re looking, check for dreys (their nests) at least six metres up, or maybe a tree hole lined with moss and leaves.
If you feed birds in your garden, you might get squirrels visiting. Reds will grab seeds and nuts from feeders, but only if there aren’t greys around.
Decline, Threats and Conservation of Red Squirrels
Red squirrels have dwindled to small, scattered groups in the UK. You’ll mostly see them in Scotland, some spots in northern England, and a handful of islands where people work hard to keep greys away.
Impact of Grey Squirrel Introduction
Grey squirrels (Sciurus carolinensis) showed up from North America in the 1800s and really shook things up in British woods. Greys are bigger and more adaptable than reds, which gives them the upper hand when food gets tight, especially in mixed or broadleaf forests.
Greys eat the same nuts and seeds but can handle a wider variety of tree seeds and young shoots. They breed fast and move into new areas quickly.
Here’s the kicker: greys carry squirrelpox, which doesn’t bother them much but is deadly for reds. If you want to help reds, managing grey numbers in the landscape makes a difference.
Threats: Squirrelpox, Predators, and Habitat Loss
Squirrelpox is a nasty virus. Greys can shrug it off, but reds usually die if they catch it. The virus spreads through direct contact and shared feeding spots.
You can help by keeping greys out of red squirrel areas and not sharing feeders between them. Habitat loss and broken-up woodlands also hurt reds.
They need big stretches of pine or well-connected woods to find food all year. Planting native trees and managing woods carefully brings back food sources like cones and hazelnuts.
Predators—foxes, birds of prey—take some squirrels, but lately, more pine martens seem to be helping reds by keeping grey numbers down in some places. Supporting habitat corridors and thinking about predators when planning woodlands really matters.
Red Squirrel Recovery and Conservation Programs
Conservation groups are out there running targeted actions you can actually support or join if you want. The Red Squirrel Recovery Network (RSRN) brings together local efforts and keeps an eye on things across England and Scotland.
Local trusts—like Northumberland Wildlife Trust and Scottish Wildlife Trust—take care of reserves and step in with grey control when it’s needed. They don’t just stop there, either.
Restoring habitats, replanting native conifers and hazel, and tackling grey squirrel numbers on a big scale all play a part. Some projects are even testing squirrelpox vaccines and looking into contraceptive options for greys.
Island populations—think Isle of Wight and Brownsea Island—really show what strict biosecurity and focused management can do for reds. If you volunteer, report sightings, or support reforestation, you can give these programs a real boost.
