Root diseases: primary agents and secondary consequences of disturbance

Publications Posted on: May 12, 2016
The fact that endemic root disease causing pathogens have evolved with forest ecosystems does not necessarily mean they are inconsequential. A pathogen such as the P group of Heterobasidion annosum has become an intractable problem in many Sierra east side pine stands in California because the fungus is adapted to colonization of freshly cut stump surfaces.

Measuring fire weather and forest inflammability

Publications Posted on: August 12, 2015
In the measurement of fire weather and forest inflammability, now practiced regularly at more than 90 forest stations in northern Idaho and western Montana, it is necessary to use many methods that are peculiar to this work. Some of these methods are familiar to meteorologists, but few foresters have had any appreciable training in meteorology.

Influence of weather factors on moisture content of light fuels in forests of the northern Rocky Mountains

Publications Posted on: August 12, 2015
The necessity of forest-fire protection is generally recognized in the United Slates. The tremendous damage done by forest fires each year to valuable timber, watershed cover, forest range, wildlife, recreational facilities, and personal property has impressed upon the people the need for preventing and controlling forest fires so far as this is humanly possible.

Meteorological conditions affecting the Freeman Lake (Idaho) fire

Publications Posted on: August 11, 2015
Measurements of meteorological conditions prevailing during the rapid spread of forest fires are greatly needed so that when their recurrence seems probable, fire-weather forecasters may issue warnings of the danger.

A five-year record of lightning storms and forest fires

Publications Posted on: August 10, 2015
According to the records compiled by the supervisors of the national forests in the northern Rocky Mountain region, lightning has been responsible for a greater number of fires, more burned area, more damage, and more expense of suppression in this territory than all other causes of forest fires combined.

Lightning and forest fires in the northern Rocky Mountain region

Publications Posted on: August 10, 2015
During the past 18 years lightning has caused 39 per cent of the forest fires in the northern Rocky Mountain district, which includes Montana, northern Idaho, and a small portion of northeastern Washington. For the seasons of 1924 and 1925 the figures are 51 per cent and 80 per cent, respectively.

Climate and forest fires in Montana and northern Idaho, 1909-1919

Publications Posted on: August 06, 2015
The present report is a result of the study of the relation between climate and forest fires in Montana and northern Idaho. This region is designated as District I of the United States Forest Service. The data used are the weather records of the United States Weather Bureau for the regular and cooperative stations, and the detail fire reports of the United States Forest Service for the years 1909 to 1919, inclusive. Mr. C. C.

Lightning fires in southwestern forests

Publications Posted on: April 20, 2015
Lightning is the leading cause of fires in southwestern forests. On all protected private, state and federal lands in Arizona and New Mexico, nearly 80 percent of the forest, brush and range fires are ignited by lightning. The Southwestern region leads all other regions of the United States both in total number of lightning fires and in the area burned by these fires.

Wildfires in Chernobyl-contaiminated forests and risks to the population and the environment: A new nuclear disaster about to happen?

Publications Posted on: October 07, 2014
Radioactive contamination in Ukraine, Belarus and Russia after the Chernobyl accident left large rural and forest areas to their own fate. Forest succession in conjunction with lack of forest management started gradually transforming the landscape. During the last 28 years dead wood and litter have dramatically accumulated in these areas, whereas climate change has increased temperature and favored drought.

Is proportion burned severely related to daily area burned?

Publications Posted on: October 03, 2014
The ecological effects of forest fires burning with high severity are long-lived and have the greatest impact on vegetation successional trajectories, as compared to low-to-moderate severity fires. The primary drivers of high severity fire are unclear, but it has been hypothesized that wind-driven, large fire-growth days play a significant role, particularly on large fires in forested ecosystems.
