Forest lands may benefit from active restoration after wildfire

100 percent tree mortality caused by the Angora fire, August 2007.
In the many forested areas where wildfires are currently burning, the question will soon arise: What should be done after the fire goes out? That depends on the severity of the burn and land owner goals.

For high severity burns where very few or no live trees remain to provide seed for the next generation, forest recovery can take a very long time. Typically forest landowners want to restore their lands to a forested condition as quickly as possible. In that case, an active approach can help them reach their goal sooner.

The California Tahoe Conservancy has just released a report on the outcomes of active restoration of 40 acres of Conservancy lands where all trees were killed by the 2007 Angora fire in South Lake Tahoe. That fire burned 3,100 forested acres as well as 250 homes.

Fire-killed trees were skidded to a landing and taken to a lumber mill, September 2007.
Post-fire Conservancy goals were to re-establish a native forest, reduce hazards posed by dead trees, and avoid water quality impacts. Contractors cut large dead trees, skidded them to a landing, loaded them on a log truck and sent to a nearby mill. Some large dead trees were left on site to provide wildlife habitat. Small trees were ground up (masticated) and left on site to control erosion and suppress competing vegetation. Then one- to two-year-old native conifer seedlings were planted.

The report's authors estimate this active approach has hastened the return to a forested condition in the area by about 60 years. This is because planted seedlings are growing quickly while there are few naturally sprouting tree seedlings in adjacent untreated areas and these face competition from vigorously growing native brush that was stimulated by the wildfire. Soil monitoring showed no compaction by heavy equipment during tree removal and minimal soil erosion. Woody mulch left on site was also effective at suppressing brush to give newly planted tree seedlings a competitive edge.

Landowners looking for guidance on post-fire forest management are encouraged to download the free UC Cooperative Extension publication “Recovering from Wildfire: A Guide for California Landowners  and consult the UC Center for Forest Research and Outreach website at

This very right that wildfire burn all the tree of the forest and after wildfire, the land which affect from the wildfire, it takes more time for become forestry land.  
This is nice blog with nice picture.  
Thank you for sharing this blog with us.

My husband would like to invest in a project that will restore those forests that experienced a wildfire. Since restoration includes, reestablishing a native forest and avoiding water quality impacts the same as what you've mentioned here. My husband would need some help from a foresty consulting service.
