TYPE FIVE TREATMENT
TYPE 5
WILDLAND URBAN INTERFACE RE -TREATMENT
WUI fuel management reduces potential fire intensity and rate of spread by reducing the fuel load in the lower forest canopy.
The rate at which post-treatment coniferous regeneration increases fuel loads is moderated by shade from retained overstory, retention of deciduous shrub vegetation, and seeding disturbed areas with ground cover mixtures.
Some restocking by conifers is, however, inevitable in a forest ecosystem.
Maintenance re-treatment is required to retain the efficacy of the initial fuel management work.
Experience shows that a re-treatment 7 to 10 years after the initial WUI fuel management when coniferous regeneration is small and easily cut with brush saws is time effective.
Post-treatment cut fuel loads are light, and can be safely disposed of by lop and scatter.
Re-treatment on a shorter time frame is not required.
Re-treatment on a longer time frame allows regeneration to grow to large size, resulting in rapidly increasing per hectare fuel management costs.
The Type 5 treatment meets fuel management goals and retains the value of previous fuel management investments.
