Patterns in understory vegetation communities across canopy gaps in young, Douglas-fir forests of western Oregon

Creator:

Fahey, Robert T.

Abstract:

Canopy gap formation is a major factor contributing to maintenance of overstory species diversity and stand structure in forests and may be integral to development of understory shrub and herb layers as well. Acknowledgement of gap formation as a fundamental feature of natural forests has led to consideration of gaps...

Impacts of fuel reduction thinning treatments on oak and chaparral communities of southwestern Oregon

Creator:

Perchemlides, Keith A.

Abstract:

In response to concerns about excessive stand densities and high-severity wildfires, land managers in the western United States are carrying out extensive programs of fuel reduction thinning. How will these sudden reductions in canopy cover and associated changes in habitat affect native and exotic herbaceous vegetation and canopy species regeneration?...

Nitrogen dynamics across silvicultural canopy gaps in young forests of western Oregon

Creator:

Thiel, Aaron L.

Abstract:

Silvicultural canopy gaps are emerging as an alternative management tool to accelerate development of complex forest structure in young, even-aged forests of the Pacific Northwest. I investigated patterns of nitrogen (N) availability along transects through 0.1 and 0.4 ha silvicultural gaps in three 50-70 year old Douglas-fir forests of western...
