HAINICH, Germany — As forester Dirk Fritzlar walks through thick woodland on a sunny September morning, it starts to “rain” spruce needles.
“It is not normal for the trees to shed so many needles. It is far too dry. Many spruce trees are dying,” Fritzlar said as he peeled off a piece of bark. He quickly finds a colony of bark beetles that are a major threat to the spruce — a common species in German forests.
In the last two years, Germany has experienced long summer droughts and rising temperatures, both of which are putting the country’s woodlands in peril.
The potential fate of this forest and millions of German trees shows the danger climate change and changing weather patterns pose to biodiversity and raises questions of how states and citizens should protect their local green spaces.
In 2018 alone, 110,000 hectares (about 272,000 acres) of forest area in Germany were damaged and 33 million cubic meters of wood — equivalent in volume to 12 Great Pyramids of Giza — were declared dead, researchers at the country’s Thünen Institute of Forest Ecosystems said.
A preliminary assessment for 2019 shows at least the same amount of damage.
German researchers and foresters have told NBC News the damage is the result of high temperatures and lack of rain drying out the trees, and in the case of the spruce, weakening its defenses against pests such as the bark beetle.
During a heat wave that hit much of Europe in July, Germany was one of several countries to break records, recording temperatures as high as 42.6 degrees Celsius (108.7 F).
