Woodland Mechanical Treatments


The chainsaw treatment involves cutting all trees larger than .5m and leaving them where they fall. Limbs were not severed from the trunk after being cut.

Tree Mastication

The Bull Hog™ treatment has been implemented at SageSTEP study sites in Utah only. All trees within mastication plots were mulched and the mulch was left where it fell.
