The great crested newt is widespread throughout Denmark. It breeds in small ponds and lakes, where it is usually most active in the evening and at night. It is recognized primarily by its dark back and yellow underside with black spots. It has many small, white warts along the sides of its body and on its back. During the breeding season, the male has a tall, serrated dorsal crest. It feeds mainly on aquatic insects, worms, and other newts. It also eats the tadpoles of the common toad, which are poisonous to most other animals.

The small pearl-bordered fritillary is in decline in Denmark and is therefore endangered and protected. It is a midsummer species whose single annual generation peaks around Midsummer’s Eve. It lives in lush forest meadows with an abundance of its host plant, common meadowsweet.

The squirrel is a mammal that lives in trees and gathers nuts, seeds, and other food. It needs trees and connected green spaces to find food, build nests, and move between habitats, as it lives in territories that it defends against other squirrels and where it builds 4–5 nests. The squirrel’s natural habitat is forests and plantations, but it has also taken over parks and gardens. The black variety is considered the native Danish squirrel and is found on Funen, especially in southern Funen, but can be seen elsewhere in the country.
