BOISE, Idaho (AP) — The Boise National Forest is planning a logging project to help get rid of diseased trees surrounding the Bogus Basin Mountain Recreation Area.

The Idaho Statesman reports that an infestation of both a parasitic plant known as dwarf mistletoe and bark beetles has devastated the forest surrounding the ski area. Forest officials say that more than half of the Douglas fir trees are infected.

The ill trees need to be replaced with other species to avoid the same diseases.

The plan calls for logging to begin in the summer of 2017. The project could take between one to three years depending on the company that wins the bid.

Some off-trail portions of the ski area will be closed while new trees grow to a size that can withstand skiers.
