Effects of Ungulate Herbivory on Aspen, Cottonwood, and Willow Development Under Forest Fuels Treatment Regimes
Year: 2012
Herbivory by domestic and wild ungulates can dramatically affect vegetation structure, composition and dynamics in nearly every terrestrial ecosystem of the world. These effects are of particular concern in forests of western North America, where intensive herbivory by native and domestic ungulates has the potential to substantially reduce or eliminate deciduous, highly palatable species of aspen (Populus tremuloides), cottonwood (Populus trichocarpa), and willow (Salix spp.). In turn, differential herbivory pressure may favor greater establishment of unpalatable conifers that serve as ladder…

Climatic, Landform, Microtopographic, and Overstory Canopy Controls of Tree Invasion in a Subalpine Meadow Landscape, Oregon Cascades, USA
Year: 2012
Tree invasions have been documented throughout Northern Hemisphere high elevation meadows, as well as globally in many grass and forb-dominated ecosystems. Tree invasions are often associated with large-scale changes in climate or disturbance regimes, but are fundamentally driven by regeneration processes influenced by interactions between climatic, topographic, and biotic factors at multiple spatial scales. The purpose of this research was to quantify spatiotemporal patterns of meadow invasion; and how climate, larger landforms, topography, and overstory trees have interactively influenced…

Citizen-Agency Interactions in Planning and Decisionmaking After Large Fires
Year: 2007
This report reviews the growing literature on the concept of agency-citizen interactions after large wildfires. Because large wildfires have historically occurred at irregular intervals, research from related fields has been reviewed where appropriate. This issue is particularly salient in the West where excess fuel conditions indicate that the large wildfires occurring in many states are expected to continue to be a major problem for forest managers in the coming years. This review focuses on five major themes that emerge from prior research: contextual considerations, barriers and obstacles…

A Practical Guide To Citizen-Agency Partnerships: Public Outreach Strategies for Fire and Fuel Management
Year: 2005
This Practical Guide is a companion to the video program Communication Strategies for Fire Management: Creating Effective Citizen-Agency Partnerships. The video is designed to assist land management personnel in working collaboratively with citizens for community fire and fuel reduction strategies. The DVD uses real world examples from successful agency communication programs to highlight effective approaches. It examines essential attributes for developing partnerships and offers a set of organizing principles to initiate an outreach strategy or to improve an existing one. This guide goes…
