| Southwest
Block
| The
Southwest (SW) Block is a steep slope and provides an excellent
opportunity to demonstrate a stand managed through low intensity,
frequent fires. Small "pocket volumes" of trees will be removed using
a four-wheel drive farm tractor and a skidding winch. The block
will be underburned following each entry, replicating the historic
fire regime typical of these forest types. Note the open structure this type of management promotes. |

Western Gall Rust (Endocronartium harknessii)
Symptoms: Swollen galls on branches or trunks (smaller diameter saplings). Hip cankers on trunk of larger trees. Yellow-orange spore pustules on galls in spring and summer. Affecting mostly two and three needle pines.
Dwarf Mistletoe (Arceuthobium spp.)
Symptoms: In response to infections, trees often produce abnormal proliferations of many small twigs which appear as a mass of twigs and foliage; these are referred to as 'witches brooms'. In the spring and early summer of the year 1/2 to 6-inch green shoots protruding from swollen areas on branches and trunk are visible.
Diplodia Tip Blight and Canker (Sphaeropsis sapinea, Diplodia pinea)
Symptoms: Last year's needles are brown usually at tips of branches. Stunted discolored needles present. Shoots appear bent or curled and small black fruiting bodies present on killed, infected needles.
