Individual tree and stand-level carbon and nutrient contents across one rotation of loblolly pine plantations on a reclaimed surface mine

Abstract While reclaimed loblolly pine (Pinus taeda L.) plantations in east Texas, USA have demonstrated similar aboveground productivity levels relative to unmined forests, there is interest in assessing carbon (C) and nutrients in aboveground components of reclaimed trees. Numerous studies have previously documented aboveground biomass, C, and nutrient contents in loblolly pine...

Response of black-water floodplain (igapó) forests to flood pulse regulation in a dammed Amazonian river

Publication date: 28 February 2019Source: Forest Ecology and Management, Volume 434Author(s): Guilherme de Sousa Lobo, Florian Wittmann, Maria Teresa Fernandez PiedadeAbstractThe monomodal flood pulse of major Amazonian rivers is a seasonal phenomenon that determines ecological and biogeochemical processes in adjacent floodplain forests. River damming transforms the pattern of downstream flood pul...

Multispecies mesocarnivore monitoring: USDA Forest Service multiregional monitoring approach

Small- to mid-sized forest carnivores, also known as mesocarnivores, are an important part of the animal community within national forests. Many forest mesocarnivores are of conservation concern and are listed as threatened or endangered under the Endangered Species Act (ESA), have been petitioned for listing under the ESA multiple times, or have designations within the Forest Service that warrant...

The phylogeography of westslope cutthroat trout

Identifying units of conservation of aquatic species is fundamental to informed natural resources science and management. We used a combination of mitochondrial and nuclear molecular methods to identify potential units of conservation of Westslope Cutthroat Trout Oncorhynchus clarkii lewisi, a taxon native to montane river basins of the northwestern United States and southwestern Canada. Mitogenom...

Social dynamics of wildland fire in California [Chapter 27]

A useful question for managers to ask is: why do we care about understanding fire’s ecological processes? At a theoretical level, knowledge itself may be the goal. However, at a more practical level, funding and research interest tends to reflect a desire to understand how to manipulate ecological processes to favor one or several preferred management outcomes. Although nature is indifferent abo...

Defining extreme wildfire events: Difficulties, challenges, and impacts

Every year worldwide some extraordinary wildfires occur, overwhelming suppression capabilities, causing substantial damages, and often resulting in fatalities. Given their increasing frequency, there is a debate about how to address these wildfires with significant social impacts, but there is no agreement upon terminology to describe them. The concept of extreme wildfire event (EWE) has emerged t...

A multi-century history of fire regimes along a transect of mixed-conifer forests in central Oregon, U.S.A

Dry mixed-conifer forests are widespread in the interior Pacific Northwest, but their historical fire regimes are poorly characterized, in particular the relative mix of low- and high-severity fire. We reconstructed a multi-century history of fire from tree rings in dry mixed-conifer forests in central Oregon. These forests are dominated by ponderosa pine (Pinus ponderosa Lawson & C. Lawso...

Recovery of small-scale infiltration and erosion after wildfires

Wildfires naturally occur worldwide, however the potential disruption to ecosystem services from subsequent post-fire flooding and erosion often necessitates a response from land managers. The impact of high severity wildfire on infiltration and interrill erosion responses was evaluated for five years after the 2003 Hot Creek Fire in Idaho, USA. Relative infiltration from mini-disk tension infiltr...

Managing wildfire for whitebark pine ecosystem restoration in western North America

Wildfire in declining whitebark pine forests can be a tool for ecosystem restoration or an ecologically harmful event. This document presents a set of possible wildfire management practices for facilitating the restoration of whitebark pine across its range inWestern North America. These management actions are designed to enhance whitebark pine resilience and health, while also being effective wil...
