That’s what you want.
Whether it comes to bark beetles, forest fires, migrating birds, elk or deer — what you want are forests with patches thick with trees, open areas and hillsides burned decades ago.
This conclusion has emerged from a series of recent studies on bark beetles and tree densities.
The studies support the underlying logic of the Four Forest Restoration Initiative (4FRI), an ambitious effort to use a reinvented, small-tree logging industry to thin the forest and diversify the landscape.
The project has lagged far behind the schedule needed to thin the first installment of 300,000 acres, mostly because the 4FRI contractor Good Earth has struggled to build up the infrastructure needed to thin 30,000 to 50,000 acres annually.
However, recent research validates the underlying blueprint for 4FRI, which would dramatically lower tree densities in the ponderosa pine forests, while creating a landscape with denser patches separated by a wide-open, thinned forest.
