Pest I.D and management please

Recommended Posts

Neighbor has some large ash trees, the ones that stand alone in the lawn are affected by these small green caterpillars each year, there’s thousands of them and strip the trees bare of leaves each year, the trees then flush again.

no other trees in the area are affected, there’s maples and apple trees they don’t touch, and the ash trees that have lilac bushes around the base are not affected, only ash trees growing in the lawn.

i know the name of the caterpillars verbally in Swedish, but not the correct spelling so can’t find the Latin.

my suggestion has been to build a chicken enclosure around the trees as the caterpillars are constantly falling down and climbing up again. . But better solutions are appreciated.
