Red squirrels are native to the UK but are a lot rarer than their grey cousins. They live in a few special places across the UK thanks to reintroduction projects.

Fir clubmoss is a primitive plant found in rocky, moorland and mountain habitats. The stems of this tufted, upright fern look like tiny conifers.

Water figwort is a tall plant of riverbanks, pond margins, damp meadows and wet woodlands. Its maroon flowers are pollinated by the Common wasp.

As its name suggests, Sea spurge is found at the coast. It is an attractive plant that displays cup-shaped, greeny-yellow flowers and fleshy, grey-green leaves.

The common octopus is a highly intelligent, active predator. It even has a secret weapon - special glands produce a venom that it uses to incapacitate its prey!

A tall plant, purple-loosestrife can form dense stands of bright purple flower spikes in wet habitats like reedbeds, fens and marshes.

A delicate, small plant of woodlands and hedgerows, wood-sorrel has distinctive, trefoil leaves and white flowers with purple veins; both fold up at night.

A scrambling plant, Common vetch has pink flowers. It is a member of the pea family and can be seen on grassland, farmland and waste ground, as well as at the coast.

Once widespread, this attractive plant has declined as a result of modern agricultural practices and is now only found in four sites in South East England.
