Four Forest Restoration Initiative

Restoring northern Arizona’s ponderosa pine forests.

In 2009, the Trust helped launch the largest forest restoration project in the country.

The Four Forest Restoration Initiative (4FRI) covers a 2.4 million-acre swath of ponderosa pine forest along Arizona’s Mogollon Rim, stretching from the Grand Canyon to New Mexico.

We’re working with the U.S. Forest Service, contractors, and dozens of partners to reduce the risk of severe wildfire, improve the health of our springs and streams, protect old-growth and wildlife habitat, and make our forests more resilient to climate change.

Power in partnerships

Large-scale restoration involves a lot of people, a lot of planning, and a lot of coordination. Day-to-day, we spend a lot of time in meetings, discussing past restoration activities and planning future thinning and prescribed burns.

Field trips

In places where restoration is underway, we visit tracts to monitor the size and spacing of trees left behind. We also look at untreated stands to determine which trees should be cut. Our field trips help us track progress and tweak plans.

Survey springs and streams

Forest restoration and the health of our water sources go hand-in-hand. We’re collecting baseline data on springs and streams so that over time, we can track the impacts of forest restoration on our water.

There are too many trees

Fire used to be frequent in the Southwest, clearing understories of grasses and saplings and maintaining open stands of trees.

But decades of fire suppression has allowed spindly trunks to crowd our national forests.

The unnaturally dense forests now fuel severe wildfires that burn hotter and longer than ever before. Add with climate change, prolonged drought, and shrinking snowpack, and the need for forest restoration has never been greater.

Description of the Kaibab Plateau, circa 1872:

“The trees are large and noble in aspect and stand widely apart, except in the highest part of the plateau where spruces dominate. Instead of dense thickets where we are shut in by impenetrable foliage, we can look far beyond and see the tree trunks vanishing away like an infinite colonnade. The grounds unobstructed and inviting. There is a constant succession of parks and glades, dream avenues of grass and flowers winding between sylvan walls, or spreading out in broad open meadows. From June until September, there is a display of wildflowers which is quite beyond description.”
