Green toads are very often reported in our project. On the one hand, green toads like to migrate and on the other hand, they are relatively easy to recognize due to their spotted skin. In Austria, however, the green toad occurs mainly in Vienna, Lower Austria and Burgenland.
There are two ways how frogs are killed on roads. On the one hand they can be rolled over directly from a tire, on the other hand they can be killed by the vacuum under the car. An avoidance maneuver in which one takes the frog between the tires is usually not useful, as speeds above 30 km / h can lead to the death of frogs.
For this reason you will not find plate frogs on roads usually, but veritable burst ones. Sometimes frogs are sitting completely motionless on the street. These are often not dead, but jump off when you touch them. Please don't enter living animals in the database.
Frogs can be identified by:
If these three criteria are met, you can enter a frog in the database.
Green toad in particular:
Green toads are mainly crepuscular and nocturnal. The green toad is bright with greenish spots on top, these characteristics usually remain visible even when the carcasses are dried.
As spring begins, for many amphibians its time to migrate. They leave their wintering grounds and start the often difficult journey to their spawning grounds. But why migrate these animals at all?
In evolution amphibians represent the transition from water living creatures to terrestrial creatures. They can move freely in the countryside, but are bound to standing or slow moving water bodies (except the Alpine salamander) for their propagation. Amphibians generally come back to the water, where they have lived as a larva. At these waters males and females meet for mating and spawning. The "egg" of amphibians are called spawn. After successful spawning, most amphibians keep ashore in search of food. In fall when the temperature drops under a species specific limit, the amphibians move back into their wintering grounds, dig themselves in, or hide under stones or dead wood.
Amphibians winter either near their spawning grounds such as the yellow-bellied toad and European tree frog, or 1-3km away like the grass frog and the common toad or even up to 10km away, such as the green toad. The further away is their spawning grounds from the wintering grounds, the higher of course is also the probability that they have to cross a road during their migration.
