An outbreak of spruce budworm across northeast Minnesota has led to widespread mortality of balsam fir, dramatically increasing wildfire risk, particularly in the Arrowhead region.

Cavity trees, dead standing trees, and downed dead trees create habitat for many species of mammals, birds, insects, amphibians, and reptiles, which positively impacts the rest of the ecosystem.
Supporting biodiversity is one of the most impactful ways to engage in forest stewardship.
Does a warm winter affect the timing of sap flow?
As our forests start changing in response to the shifting climate, newcomer trees are poised to expand their range toward us as conditions here become more hospitable.
Forest ecosystems include trees, plants, and wildlife, and the diverse belowground world of soil. Being a forest caretaker also means being a caretaker of the soil.
Diverse woodlands provide wonderful habitats for native pollinators. We’re shedding some light on how woodlands can be managed with pollinators in mind.
Tree species at the southern edge of their current range will face increasing climate stress, and hardwoods not currently seen in Minnesota may slowly take their place.
It’s easy to admire the beauty of the winter landscape. But what about everything that we can’t see? What happens to the forest during the winter?
While subzero temperatures are not the most pleasant conditions for us, they can be a factor in helping to control pests. Warmer winter temperatures may mean more EAB larvae are likely to survive.
