Restoration of oaks in Sonoma using fire mimicry

26 09 2011

Last week I visited an oak grove in Sonoma where restoration efforts using fire mimicry began in 2009. Several of the coast live oaks had symptoms of Sudden Oak Death, and many other oaks were in rather poor health. Underbrush was cleared, dead branches were pruned, mosses and lichens were removed from the trunks, minerals were applied to the soil along with compost and mulch, and the trunks sprayed with a mineral-rich lime spray.

After this work began several of the oaks have since been heavily impacted by some new home construction. Despite this, most of the impacted oaks have shown a noticeable improvement in their health over the two year period. The photos below show the results.
