Reforestation on the Rogue River-Siskiyou National Forest on the Powers and Gold Beach Ranger Districts is driven by the need to accelerate the development of late successional habitat in stands less than 80 years old. Prior regeneration harvest emphasized clear-cutting with regeneration of Douglas-fir. Douglas-fir is not a shade tolerant species and will not regenerate naturally under canopy cover.
Drought is a prominent feature of Hawaiʻi’s climate. However, it has been over 30 years since the last comprehensive meteorological drought analysis, and recent drying trends have emphasized the need to better understand drought dynamics and multi-sector effects in Hawaiʻi.
Landowners value and care for their forests for reasons that include improved wildlife habitat, aesthetics, recreation, and timber. In Washington, 15% of forested lands are owned by small forest landowners (2-2500 acres). As such, the management decisions of small forest landowners can have implications for all of Washington's forests.
Characterizing pre-fire fuel load and fuel consumption are critical for assessing fire behavior, fire effects, and smoke emissions. Two approaches for quantifying fuel load are airborne laser scanning (ALS) and the Fuel Characteristic Classification System (FCCS).
We used historical and contemporary survey data to assess the dynamics in two old-growth forests at Savage Mountain, Maryland, versus secondary forests from the surrounding landscape of the northern Allegheny Mountain Plateau (AMP). This is the first published compilation of witness trees from western Maryland. The oldgrowth forests on Savage Mountain, Maryland, are presently dominated by mixed oak (Quercus spp.
The regulation of seasonality has been an area of interest for decades, yet global climate change has created extra urgency in the quest to understand how sensory circuits and neuroendocrine control systems interact to generate flexibility in biological timekeeping.
In an age of increased anthropogenic changes, it is crucially important to understand how and why ecological communities change. Community assembly is governed by colonization and extinction processes, and the simplest model describing it is dynamic equilibrium (DE), which assumes that communities are shaped solely by stochastic colonization and extinction events.
Wildland fires are fundamentally landscape phenomena, making it imperative to evaluate wildland fire strategic goals and fuel treatment effectiveness at large spatial and temporal scales. Outside of simulation models, there is limited information on how stand-level fuel treatments collectively contribute to broader landscape-level fuel management goals.
Invasive alien species (IAS) are a rising threat to biodiversity, national security, and regional economies, with impacts in the hundreds of billions of U.S. dollars annually. Proactive or predictive approaches guided by scientific knowledge are essential to keeping pace with growing impacts of invasions under climate change.
Plant invasions can alter food resources and habitat conditions that structure animal communities. These effects are negative for many native animals, but neutral or even positive for others. Understanding why we see this variation in responses is critical for mitigating invasion outcomes, yet we lack a synthetic framework to explain and potentially predict effects of invasive plants on native animals.
