Planting a tree may seem like a simple act. But when a wildfire sweeps through a National Forest and leaves nothing but standing dead trees and ashes, there is an important, multi-step process in place to help restore the forests. Learn how we restore forest cover following major natural disturbances like wildfire.
Area and Design
Each reforestation project responds to a specific need. Wildfire commonly creates a lot of reforestation need, especially in the Western U.S.
Before beginning any part of the reforestation process, the U.S. Forest Service first carefully assesses the area in need, considers the tree species that were present, and evaluates whether or not the area will benefit from tree planting or natural regeneration.
If the area would benefit from tree planting, they make a plan for exactly how the forest will be planted.
Did you know? Not all areas affected by wildfire are replanted. Some areas will grow back naturally and without intervention.
The Forest Service sources native seeds from healthy forests near the area to be planted. Sometimes climbing high into trees to obtain the seeds, the U.S. Forest Service collects cones from the same species that they plan to plant, and from the same elevation. Cones are then broken down to extract seeds.
Growing At the Nursery
After the Forest Service collects seeds, they transport them to one of six Forest Service nurseries located across the country. Here, professionals grow them under climate- controlled conditions that mimic their natural environment.
Seedlings are typically grown until they are 1-2 years old, although some species require more time. Once seedlings reach a sufficient age, they are transported back to forest for planting.
Did you know? Forest Service nurseries supply the vast majority of seedling planted on National Forests.
The Forest Service then transports the seedlings back to the forest in a refrigerated cooler until the morning that they are planted. Professional tree planting crews fill up their hip bags with hundreds of seedlings at once, and trek across hillsides to plant seedlings.
To give a better chance at survival, seedlings are often planted in what are called “microsites” – tucked in or shaded areas that protect the seedling from direct sun exposure.
Using specialized tools, planters dig a small, deep hole in the ground. Seedlings are carefully placed in the hole, making sure the root structure is intact and covering the opening with soil.
Did you know? A professional tree planter can plant a tree in less than 10 seconds!
To ensure that seedlings were planted correctly, the Forest Service will randomly select young seedlings and dig them up to confirm the crews used the proper planting technique.
As seedlings mature, the Forest Service monitors them after one, three and sometimes five years of planting to ensure survival.
In some areas, follow up maintenance activities (like scraping away competing vegetation) are necessary to ensure seedlings survive into the future.
Funds contributed to our tree planting efforts are critical in enabling these reforestation projects to happen.
