Abstract of research plan for: Effects
of fuel reduction and forest restoration activities on forest understory
composition and diversity.
In fire-prone ecosystems of the interior Northwest,
resource managers have begun to experiment with reducing fuel loadings and
manipulating forest structure, thus redirecting the future trajectory of stand
development. Increasingly, managers
are employing thinning and prescribed burn treatments to achieve both short-
and long-term changes in stand structure.
A fundamental goal of these activities is to restore some of the structural
elements, species, and ecosystem processes that characterized these forests
prior to widespread suppression of wildfire.
However, the potential consequences of these activities for other forest
attributes are not fully understood. For
example, basic information on plant community responses to thinning and fire
are essential if resource managers are to assess conditions and trends, or
are to develop sound management strategies that enhance wildlife habitat and
other components of biological diversity.
This recently initiated research seeks to address this
need through: (1) a comprehensive
review and synthesis of the current-state-of-knowledge on understory responses
to forest management in fire-prone forest ecosystems; and (2) a large-scale
sampling effort to quantify the role past management practices, time since
“treatment,” and physical environment
on vegetation composition, structure, and diversity. We are addressing the following questions:
