|
Thinning |
attractive, park-like | low risk | labor intensive | small diameter only | slash left to treat |
| Slashbuster: Thinning | cost-effective | perform
multiple tasks at one time; no slash |
for
use on gentle slope only |
can disturb soils | can damage leave trees/spread noxious weeds |
| Pruning | attractive landscape | effective | very labor intensive | creates slash | |
| Slashing | easy to describe | labor intensive | could end up a clear-cut | ||
| Slashbuster: Slashing | cost effective | perform
multiple tasks at one time; no slash |
for
use on gentle slope only |
can
disturb soils; spread noxious weeds |
can damage leave trees |
| Lopping & Scattering | low cost | few impacts on lands | labor intensive | not all fuel removed | small diameter only |
| Fuel Pullback | low cost | effective | labor intensive | larger slash = many cuts | |
| Crushing - dozer | easy & inexpensive | possibly reduces fire intensity | does not prevent fires | possible soil compaction | not for use on large or green material |
| Slashbuster: Chipping | cost-effective | perform
multiple tasks at one time; no slash |
for
use on gentle slope only |
can
disturb soils; spread noxious weeds |
can damage leave trees |
| Hand Piling | easy to do | few impacts on lands | slow work | time consuming | |
| Burn Hand piles | easy to implement | labor intensive | leaves big black spots on ground | ||
| Machine Piling | fast | inexpensive | possible
soil compaction |
topsoil
can be moved; spread noxious weeds |
not attactive |
| Machine Pile - Burn | easy to implement | labor intensive | leaves big black spots on ground | ||
| Raking | can significantly protect large trees | very labor intensive | |||
|
Prescribed Fire |
|||||
| Underburn - Broadcast burn | accomplishes multiple tasks |
can
mimic a natural regime |
risks
if fire gets away from operator |
requires experienced personnel | leave trees can be damaged |
| Fireline Construction | provides ground barrier to fire | labor intensive | requires maintenance | not completely effective | |

|
Grazing |
can be low-cost | minimal
labor if water & fencing in place |
may compact soils | affects
small diameter material only; < 3" |
fencing
& water needed |

Lomakatsi Natural |
attractive, park-like | site-specific
consultations prior to treatments; protects resources |
labor intensive | can be slow process | |
