In the same area as the oaks I reported on in the previous post, I also inspected some ponderosa pine trees that have received fire mimicry treatment. These are photos of the pines after 5 years of treatment. While the responses of the pines are not as dramatic as seen in the nearby oaks, there is a noticeable improvement in canopy density of the pines. For comparison, the last photo set shown is of an untreated pine.
For comparison with above photos, note that the photo set below are of an untreated Ponderosa pine.
