  1. Wood and bark percentages and moisture contents of Minnesota pulpwood species.

    To help increase the use of bark for fuel or products, information is presented on the relative proportions of bark and wood by volume and weight, and also moisture contents (ovendry basis) for five northern Minnesota pulpwood species.

  2. Opportunities to use bark polyphenols in specialty chemical markets

    Current forestry practice in North America is to transport pulpwood and logs from the harvest site to the mill with the bark on the wood. Approximately 18 percent of the weight of logs from conifers such as southern pine is bark. The majority of this bark is burned as hog fuel, but its fuel value is low. When compared with natural gas at an average of $2.50/MBTU or...

  3. Fuel and fire behavior in high-elevation five-needle pines affected by mountain pine beetle

    Bark beetle-caused tree mortality in conifer forests affects the quantity and quality of forest fuels and has long been assumed to increase fire hazard and potential fire behavior. In reality, bark beetles and their effects on fuel accumulation and subsequent fire hazard have only recently been described. We have extensively sampled fuels in three conifer forest types...
