The US Endangered Species Act has enabled species conservation but has differentially impacted fire management and rare bird conservation in the southern and western US.
Nutrient loading in the fall is a practical way to improve seedling quality and has been proven to increase nutrient accumulation, translocation and utilization. Few studies have reported on the variation in free amino acids as a result of fall fertilization, especially for different seasonal needle habits (evergreen, deciduous).
In recent decades, container stock has become the preferred plant material to regenerate longleaf pine (Pinus palustris Mill.) forests in the southeastern United States. We evaluated the effects of container nursery treatments on early and long-term field performance in central Louisiana.
First-year outplanting performance was measured in guindo santo (Eucryphia glutinosa (Poepp. & Endl.) Baill.), a Chilean endemic tree species in the Mediterranean climate zone, which is catalogued as a near-threatened species. The effects on survival of initial plant size, fertilization at establishment, and shade (with or without nurse trees) were evaluated during the first growth season.
Our objective was to better understand how organic and inorganic nitrogen (N) forms supplied to a tree, Robinia pseudoacacia, and a perennial forb, Lupinus latifolius, affected plant growth and performance of their symbiotic, N-fixing rhizobia. In one experiment, we tested five sources of N [none; three inorganic forms (ammonium, nitrate, ammoniumnitrate); and an organic form (arginine)] in combination with or without rhizobia inoculation.
Post-fire flooding and elevated sediment loads in channels can pose hazards to people and structures within the wildland-urban interface. Mitigation of these hazards is essential to protect downstream resources. Straw bale check dams are one treatment designed to reduce sediment yields in small ephemeral catchments (b2 ha).
Despite the generally accepted need for understanding social vulnerability within the context of USDA Forest Service planning and management, there is a lack of structured approaches available to practitioners to gain such an understanding.
Forest fragmentation and degradation are a problem in many areas of the world and are a cause for concern to land managers. Similarly, countries interested in curtailing climate change have a keen interest in monitoring forest degradation.
Despite major advances in numerical weather prediction, few resources exist to forecast wildland fire danger conditions to support operational fire management decisions and community early-warning systems. Here we present the development and evaluation of a spatial fire danger index that can be used to assess historical events, forecast extreme fire danger, and communicate those conditions to both firefighters and the public.
This report presents a summary of the most recent Forest Inventory and Analysis summary of Montana’s forests based on field data collected between 2006 and 2015. The report includes descriptive highlights and tables of area, numbers of trees, biomass, volume, growth, and mortality, as well as an industry report. Most sections and tables are organized by forest type or forest-type group, tree species group, diameter class, or owner group.
