You’ve already mentioned that coastal forests are better able to cope with drought. How has the drought of recent years affected the health of Usedom’s forests?
The water table has dropped significantly due to the drought. It is now up to 1.5 meters lower than usual. Naturally, that puts a strain on the trees. We monitor the condition of the forest very closely, primarily by closely observing the tree crowns and foliage.
One clear sign that the trees are weakened, for example, is that the oaks on the island carried a very large number of acorns last year. Normally, oak trees reproduce only every seven to ten years in what’s known as a “full mast” year. Because conditions were so poor, the trees essentially panicked and tried at all costs to produce offspring. That’s why even more acorns were produced last year—but this, in turn, weakens the tree because it requires a significant amount of energy. This year, we’ve observed the same phenomenon with the beech trees.
The trees on Usedom are able to compensate quite well for the lack of precipitation through increased humidity. But “compensating” simply means that problems and damage aren’t immediately noticeable. The trees are suffering nonetheless. And I also expect that the health of these two species in particular will be worse in the coming years than I would like. However, I am hopeful that the situation here will not be as drastic as in other parts of the country further south.
