Seedling Responses of Five Species of Western Conifers to Simulated Ambient Sulfur Dioxide Exposures

Seedlings of ponderosa pine, Douglas-fir, white fir, Engelmann spruce, and subalpine fir were exposed continuously to charcoal-filtered (CF) air or one of three levels of a simulated ambient exposure typical of SO, pollution near smelters in the western United States. Seedlings were exposed during winter-spring experiments for 60 days to hourly means of 17, 38, and 54...

The survival of Pinus ponderosa saplings subjected to increasing levels of fire behavior and impacts on post‐fire growth

Improved predictions of tree species mortality and growth metrics following fires are important to assess fire impacts on forest succession, and ultimately forest growth and yield. Recent studies have shown that North American conifers exhibit a ?toxicological dose?response? relationship between fire behavior and the resultant mortality or recovery of the trees. Prior...

Coopers Rock Crop Tree Demonstration Area—20-year results

During the 1988/1989 dormant season, the Coopers Rock Crop Tree Demonstration Area was established in a 55-year-old central Appalachian hardwood forest in north-central West Virginia. After treatment, 89 northern red oak (Quercus rubra L.) and 147 yellow-poplar (Liriodentron tulipifera L.) crop trees were monitored for 20 years....

Remeasured FIA plots reveal tree-level diameter growth and tree mortality impacts of nitrogen deposition on California’s forests

The air in California?s forests spans a broad range of purity, from virtually no locally generated pollutants to highly elevated levels of pollutants in forests downwind of urban and agricultural source areas. Ten-year remeasurement data from Forest Inventory and Analysis (FIA) plots in California were used in combination with modelled atmospheric nitrogen (N)...

Planting nonlocal seed sources of loblolly pine - managing benefits and risks

Seed source testing of loblolly pine (Pinus taeda), which began in the 1920s, has allowed large realized genetic gains from using nonlocal seed sources in operational plantations. Seed source testing continues, and deployment guidlines are being refined. some general effects of seed source movement can be described, but there are still gaps in (1)...

Effect of large-scale movement of loblolly pine seed on genetiv integrity of the species in its natural range

Geographic variation of the major southern pine species has been well studied. Seed collected from different geographic areas vary greatly in their potential for growth and survival depending on where they are planted. In seed source studies of forest tree species, it is often observed that sources from warmer climates grow faster than local sources as long as they are...

Coast live oak, Quercus agrifolia, susceptibility and response to goldspotted oak borer, Agrilus auroguttatus, injury in southern California

Oak mortality is often associated with a complex of decline factors. We describe the morphological and physiological responses of coast live oak, Quercus agrifolia Née, in California to an invasive insect, the goldspotted oak borer (GSOB), Agrilus auroguttatus Schaeffer (Coleoptera: Buprestidae), and evaluate drought as a...

The altitude of alpine treeline: a bellwether of climate change effects

Because of the characteristically low temperatures and ambient CO₂ concentrations associated with greater altitudes, mountain forests may be particularly sensitive to global warming and increased atmospheric CO₂. Moreover, the upper treeline is probably the most stressful location within these forests, possibly providing an...

Xylem hydraulic safety margins in woody plants: coordination of stomatal control of xylem tension with hydraulic capacitance

The xylem pressure inducing 50% loss of hydraulic conductivity due to embolism (P₅₀) is widely used for comparisons of xylem vulnerability among species and across aridity gradients. However, despite its utility as an index of resistance to catastrophic xylem failure under extreme drought, P₅₀ may have no special...

An annual pattern of native embolism in upper branches of four tall conifer species

The Pacific Northwest of North America experiences relatively mild winters and dry summers. For the tall coniferous trees that grow in this region, we predicted that loss in the hydraulic conductivity of uppermost branches would be avoided because of difficulty reversing accumulated emboli in xylem that is always under negative pressure. To test this hypothesis, we...

A method for ensemble wildland fire simulation

An ensemble simulation system that accounts for uncertainty in long-range weather conditions and two-dimensional wildland fire spread is described. Fuel moisture is expressed based on the energy release component, a US fire danger rating index, and its variation throughout the fire season is modeled using time series analysis of historical weather data. This analysis...

Regeneration responses in partially-harvested riparian management zones in northern Minnesota

Trees serve important functions in riparian areas. Guidelines often suggest how riparian forests should be managed to sustain functions, including tree retention and increasing the component of conifers and later-successional species. While regeneration of early successional species is not discouraged, there is uncertainty about the ability to regenerate the latter...

Planetary boundaries: exploring the safe operating space for humanity

Anthropogenic pressures on the Earth System have reached a scale where abrupt global environmental change can no longer be excluded. We propose a new approach to global sustainability in which we define planetary boundaries within which we expect that humanity can operate safely. Transgressing one or more planetary boundaries may be deleterious or even catastrophic due...
