Managing disease outbreaks, insect infestations, and other
disturbances to reduce fire hazard
This study aims to characterize how diseases, insects, and other
small-scale disturbances influence spatial patterns of fuel loading.
It uses easily accessible satellite imagery and spatial statistics
to model distribution of various types of fuels at landscape scales
with 10 m resolution. Application of these models have the potential
of helping managers develop guidelines for mediating fire hazard
by managing spatial patterns of outbreaks.
Limit fuel buildup by controlling diseases and other mortality
We developed a method to measure the relative importance of different
disturbances in creating fuels and changing the spatial fuel distribution
at landscape scales. In our test case of endemic conditions in the
Black Hills NF, root diseases caused 32% of the total fuel load,
followed by bark beetles (21%), lightning damage (11%), wind damage
(10%), canker diseases (10%), and others. Cash flow analyses with
capital budgeting methods are being used to estimate values resulting
from controlling different disturbances. These methods will help
managers conduct costs/benefit analyses and decide on whether controls
for different disturbances are economically justifiable.
Development of spatial fuel models based on satellite imagery
Methods were developed to generate spatial fuel loading models that
predict the spatial distribution of various fuel components at a
10 m resolution. These models have been linked to established fire
spread models to predict spatial spread and impact. Application
of these models offer a nice way to monitor fuel abundance and distribution
at landscape scales, and monitoring fuel load distributions as they
change with disease and insect activities.
