It's over at the fence: During their migration, the amphibians are first slowed down and then brought in buckets over the Kreuther B 307.

The amphibian migration in the Miesbach district began earlier than usual.
The frog fences in Kreuth and also at Suttensee are now in place.
It's high season for animal rights activists.
Kreuth/Rottach-Egern
– The grass frogs are already migrating.
Thomas Doreth recently brought around 900 animals from A to B, i.e. to their spawning waters on the other side of the B 307, in one morning.
The common toads will soon join in and demand even more effort from Doreth and his volunteers.
“We make sure we get them all across well,” says the tireless animal rights activist.
The frog fence has been built on the B 307 in Kreuth since 2014
Since March 2014, a frog fence has been installed every spring between the end of Kreuth and Wildbad Kreuth on both sides of the busy federal highway to protect the love-crazed amphibians.
Doreth has been committed to the topic for just as long.
On strong days, up to 4,500 toads are brought across the road
This year the toads are particularly early; the unusually mild climate has already attracted some of them from their winter quarters, Doreth knows.
He is happy to be able to rely on a permanent group of six to eight helpers who support him in his daily work for the amphibians.
After all, on busy days there can be up to 4,500 animals that have to be picked up in Kreuth early and in the evening and brought across the street.
The Miesbach district office with its lower nature conservation authority has already described the Kreuth amphibian population as “one of the largest and most important” in the Miesbach district.
Neuer and Rabl donated a frog fence for Suttensee
For Doreth, who works full-time at the Rottach-Egern animal shelter, a new task was added this year.
He also coordinates the helpers for the new amphibian fence at Suttensee in the Rottach-Egern municipality.
There, the renovators of the Valepp forestry lodge, Manuel Neuer and Johannes Rabl, had a frog fence jumped after the Tegernsee Valley Protection Association (SGT) and other conservationists drew attention to the amphibian population there.
There was great concern that the increased use of the toll road - including by construction vehicles - could result in mass deaths of animals.
The situation at Suttensee is completely new territory for the helpers
Doreth reports that the frog fence at Suttensee has been put up recently.
He has already been able to get a few helpers to help out up there.
“But overall,” says Doreth, “this is new territory for us on the Sutten.”
First of all, you have to do some kind of monitoring in order to find out exactly where the amphibians come from up there and which routes they use to migrate to the spawning waters.
“We don’t yet know what to expect,” Kreuther points out.
Doreth expects that the amphibians will now slowly become active in the Suttensee area.
“As soon as the fence is up, we have to check it,” he says.
As far as the occurrence in Kreuth is concerned, Doreth has been campaigning for several years for a permanent amphibian crossing with an underground passage to be built.
This could replace the temporary frog fence and would protect the animals all year round.
According to Doreth, the specialist departments are currently evaluating reports.
“It’s my turn,” he assures.
