Freshwater

The rain-soaked lands of Britain and Northern Ireland are rich in rivers, streams, lakes, ponds, canals and ditches. Whether natural or artificial, they are the life-force behind the wildlife we love.

Species in freshwater habitats in Kent

European spoonbill

The distinctive sight of a spoonbill is becoming increasingly common in the east and southwest of England, with colonies of breeding birds now established.

Osprey

A great way to get up close and personal with the magnificent osprey is via one of the many nestcams set-up in the places that it breeds: Scotland, Cumbria, Wales and the East Midlands.

Kingfisher

Blink and you may miss the fantastic kingfisher! This beautiful bird is easy to recognise thanks to its bright blue and metallic copper colours. It darts along the riverbank or sits patiently on a low branch over the water waiting for its next meal to swim by.

Smew

This small duck is an uncommon winter visitor to the UK, where they're usually found on lakes, reservoirs and gravel pits.

Bittern

The shy and retiring bittern is a master of blending in and can be very difficult to spot in its reedbed home. It does sound like a booming foghorn, however, when it calls, so can often be heard if it cannot be seen.

Water shrew

The large, dark grey water shrew lives mostly in wetland habitats. It's a good swimmer that hunts for aquatic insects and burrows into the banks.

Grass snake

The grass snake is our longest snake, but don't worry if you find one in the compost heap - it's harmless! Look out for this green and yellow beauty in grasslands and wetlands, too.

Common frog

Our most well-known amphibian, the common frog is a regular visitor to garden ponds across the country, where they feast on slugs and snails. In winter, they hibernate in pond mud or under log piles.

Palmate newt

The palmate newt looks similar to the smooth newt, but favours shallow pools on acidic soils like heathlands. During the breeding season, males grow distinctive black webbing on their hind feet.

Common toad

Despite its warts and ancient associations with witches, the common toad is a gardener's friend, sucking up slugs and snails. It is famous for migrating en masse to its breeding ponds.

David Tipling

Marsh harrier

The courtship of the marsh harrier is certainly a sight to behold - wheeling and tumbling through the sky, male and female partners lock talons in mid-air. Look out for this rare bird over reedbeds in East Anglia, Somerset and the South East.

Andy Morffew

Hobby

Look out for the swift-like shape of the hobby as it darts over heathlands and wetlands in summer. They are keen hunters, chasing and catching fast-flying dragonflies and small birds on the wing.

Great crested newt

With its prominent, wavy crest, the great crested newt, also known as the 'warty newt', looks like a mini dinosaur! This protected species favours clean ponds during the breeding season.

Bullhead

Living up to its name, the bullhead has a characteristically large, flattened head and a tapering body. Look out for it in fast-flowing, stony rivers and streams.

Chub

The silvery chub can be seen gathering in large shoals in lowland rivers and streams. It is a member of the carp family and looks very similar to the dace, but is larger and has redder fins.

Scarlet tiger moth

This beautiful moth is often found resting on leaves, though it does also fly during the day.

Banded demoiselle

The Banded demoiselle can be seen flitting around slow-moving rivers, ponds and lakes. The males are metallic blue, with a distinctive dark band across their wings, and the females are a shiny green.

Brown trout

A fierce predator of small fish and flying insects, the brown trout is widespread in our freshwater rivers. It is has a golden body, flanked with pale-ringed, dark spots.

Types of freshwater habitats in Kent

Chalk streams

Habitat

Cool, crystal-clear waters flow over gravelly beds, streaming through white-flowered water-crowfoot and watercress in serene lowland landscapes.

Lakes

Habitat

Lakes come in many forms: some are splendid and clear, while others are more reminiscent of a murky swamp. Each lake is strongly influenced by the underlying lakebed and the surrounding landscape, and collectively, lakes support a huge variety of animal…

Ponds

Habitat

Whether found in a garden or part of an agricultural landscape, ponds are oases of wildlife worth investigating. Even small ponds can support a wealth of species and collectively, ponds play a key role in supporting freshwater wildlife.

Rivers

Habitat

From otters to freshwater shrimps, all animals are dependant on an abundant and reliable supply of clean water. Rivers sustain the natural environment, wildlife and people in equal measure.
