  • The impact of beetle-induced conifer death on stand-scale canopy snow interception

    Bark beetles have killed more than 100,000 km2 of pine forest in western North America, causing trees to lose the majority of their canopy material and potentially leading to enhanced subcanopy snow accumulation. Over a 45-day period, we tested this hypothesis by measuring daily snow accumulation in three living and two dead lodgepole pine stands and in three adjacent clearings. The largest ...

  • Wood briquettes with an innovative form

    Briquetting has allowed one wood processing firm to optimise its strategy for increasing value and has led to the creation of a new line of business. Robeta OHG operates a saw mill in Brandenburg, Germany. The company processes around 280,000m3 of pine wood a year, which is sourced exclusively in the forests of Brandenburg and Mecklenburg-Vorpommern. Instead of selling on loose ...

  • Air‐plant exchange of brominated flame retardants at a rural site: Influencing factor, interspecies difference, and forest scavenging

    Brominated flame retardants (BFRs) in eucalyptus leaves and pine needles from a rural site in southern China were measured to investigate the air‐plant exchange. The mean concentrations of BFRs were higher in pine needles (79.8 ng/g dry weight) than in eucalyptus leaves (74.5 ng/g), whereas an inverse result were found for the leaf surface particles (LSPs), with mean concentrations of 3490 and ...

  • The fate of lead at abandoned and active shooting ranges in a boreal pine forest

    Changes in leaching, availability, bioaccumulation, and vertical distribution of lead (Pb) in soil 20 years after the cessation of shooting activity were studied by comparing three pine forest sites in southern Finland: an active shooting range, an abandoned shooting range, and a noncontaminated control site. At both shooting ranges, shooting activity had lasted for 20 years, but it had taken ...

  • Aspect and soil textural controls on snowmelt runoff on forested Boreal Plain hillslopes

    Plot studies were conducted on a jack pine forest with sandy soil and aspen forests with sandy and loam soils to examine the controls of slope aspect, soil texture and fall soil moisture content on near-surface snowmelt runoff and infiltration. It was hypothesized that near-surface runoff would be greater from north-facing slopes on loam soils with increased fall soil moisture content. Fall soil ...

  • Organic acids and Aldehydes in throughfall and dew in a Japanese pine forest

    We analyzed low molecular weight organic acids and aldehydes in throughfall under pine forest, and organic acids in dew on chemically inert surfaces and pine needle surfaces at urban- and mountain-facing sites of pine forest in western Japan. Low molecular weight organic acids and aldehydes accounted for less than 5% of the dissolved organic carbon in throughfall at both sites. Formaldehyde at ...

  • Seven decades of Calcium depletion in organic horizons of Adirondack forest soils

    We used repeated sampling of the forest floor to determine if there was a net loss of Ca from organic horizons of Adirondack forest soils between 1930 and 2004. In 1984, we established 48 permanent plots in spruce–fir, northern hardwood, and pine stands located in areas sampled by Carl C. Heimburger in the early 1930s. Following Heimburger's protocols and analytical methods, we measured pH and ...

  • Basics of evapotranspiration

    Evapotranspiration (ET) represents the loss of water from the Earth’s surface from the combination of direct evaporation and plant transpiration. ET is usually expressed as a rate such as inches per day. Knowledge of ET is important for irrigation scheduling but it is also an important factor for other land use applications such as septic tank drain fields, water shed water budgeting, and climate ...

  • Toward a sustainable bioeconomy: A first nations perspective

    Dan George thanked the Lheidli T’enneh First Nation for “the opportunity to gather on their traditional territory.” George said his key message was articulated by Satsan, the Wet’suwet’en hereditary chief, who said, “People must understand that our activity on the land is not a result of the mountain pine beetle epidemic. It is a result of Aboriginal title and rights.” In September 2005, First ...
