lands where the lack of active management leads to higher mortality from drought, insects, disease, and wildfire. Tribes tend to respond more quickly to address forest health issues through silviculture treatments and salvage operations than
agencies managing federal lands. Drier, fire-prone tribal lands are not immune to fuel accumulation issues and the impacts of climate change (longer fire seasons and drier fuels), but repeated examples were observed of tribal lands actively managed to be
multi-aged using partial harvests (thinning and gap creation) and prescribed burning to increase resistance and resilience to wildfires – a pattern much more apparent on tribal lands than National Forest lands. In the Lake States and Eastern regions,
