Around March 20th the frog migration started at our Olešná lake. Frogs breed in the water.

There is a car road between the forest and the lake. Most frogs die on the way.

My friends and I made a frog fence at Saturday.

Frogs can't cross the fence. We must pick them up several times a day.

We shipped 450 of them tonight between 7pm and 9pm.
Migration takes about a week. I'll write frog news during the week.
