Wildfire risk in times of climate change

Climate change is talked about a lot nowadays. Institutions are trying to find possibilities to comply with the 2°C-target to keep climate change in a tolerable dimension. This article is supposed to depict the correlation between climate change and increasing wildfire risk.

Bark beetles, beware: The three-toed woodpecker!

Three-toed woodpeckers predominantly prey on bark beetles and play a key role in controlling beetle populations in forests dominated by conifers. Their impact is greatest where they occur year-round and thus also breed there. For this, the average deadwood volume needs to be at least 33 m3 per hectare.
