The tree frog and other amphibian

All amphibians are protected
There has been amphibians living on earth for millions of years, and it is reckoned that just 50 years ago the stock of amphibians was 5 times higher then it is today. 14 species of amphibians is found in Denmark, 9 of them is living in the Sønderborg-area and 5 of these are under strict protection.  

The amphibians under strict protection is; European tree frog, Common spadefoot, Natterjack toad, Moor frog and Northern crested newt.

Amphibians breed in water
Many ponds have vanished in the wish of more farm land or need of space for housing. In the municipality Sønderborg Kommune, an amazing cooperative with private enthusiasts has helped recreate many ponds. However, recreating ponds is not enough, they also need maintenance so they don´t become choked.

Observe the amphibians and learn more
Catching tadpoles and observing their development is extremely facsinating. On island Als it is allowed to collect tadpoles excepted those of the tree frog. It is important that you release the tadpoles or developed frogs back in to the same pond.

Natterjack toad
This toad is found at the beach and in areas of sandy tidal meadows with barren vegetation.

Northern crested newt
This newt is recognized by its warty skin and the orange-yellow belly with black spots. After the larva is developed in to an adult newt, it stays on land and only return to the water during breeding season. 

Moor frog
It is easy to confuse the Moor frog with the Common frog, however there are some distinctive features of the Moor frog, like the knot at the inner toe of the hind legs and the white or yellowish belly without pattern, where the belly of the Common frog is spotted.

Common spadefoot
Also known as Garlic toad. Outside breeding season, the Common spadefoot likes to live in areas of loose and sandy earth surface. The soil in the Sønderborg-area is very good fertile clayey soil, however with some luck you should be able to find the Common spadefoot on the most northern part of island Als and on the mainland, near Tørsbøl.  

European tree frog
Island Als has a very central role in the future of the Tree frog. It is right here, Denmark´s largest population of this little green frog is found. The clear green colour makes it extremely recognizable, however you must remember to look up during the search, it likes to sit between leafs of green.

Amphibians are vulnerable
The amphibians need ponds of clean water without fish! Release of fish in pools and ponds is a threat towards the amphibians; fish eat their eggs and larva. Another threat is duck feeding which leads to water pollution.
