Fusarium circinatum is a fungal plant pathogen that causes the serious disease pitch canker on pine trees and Douglas firs (Pseudotsuga menziesii).The most common hosts of the pathogen include slash pine (Pinus elliottii), loblolly pine (Pinus taeda), Monterey pine (Pinus radiata), Mexican weeping pine (Pinus patula), and Douglas fir.

The nematodes drop off the beetle, and infect healthy pine trees when the adult beetles eat the young pine branches. [16] The pine wilt nematode is spread by a number of bark beetles and wood borers, typically associated with the genus Monochamus of pine sawyers. [17] Pine sawyers lay their eggs in the bark of dead timber.
Ill-health of trees can be diagnosed, and early treatment, pruning or felling to prevent the spread may result in timber stocks and amenity trees being saved. Tree owners and Arborists/arboriculturists need to be aware of the risk posed by hazardous trees. Construction projects sometimes avoidably damage trees.

These are pine, spruce, hemlocks, cypress and cedar trees. Wax-leaf trees, like magnolia and hollies, are also In this category. The coniferous trees make up 29%, of canopy In Wake County.
This includes offsetting their carbon emissions and tree planting. So far over 50 million trees have been planted through Ecologi, as well a more than 2.2 million tonnes of CO2e reduced.
