Interrelationships among light, photosynthesis and nitrogen in the crown of mature Pinus contorta ssp. latifolia

Scaling leaf-level measurements to estimate carbon gain of entire leaf crowns or canopies requires an understanding of the distribution of photosynthetic capacity and corresponding light microenvironments within a crown. We have compared changes in the photosynthetic light response and nitrogen (N) content (per unit leaf area) of Pinus contorta Dougl. ssp. latifolia...

Economic values of metro nature health benefits: A life course approach

tThe presence of metro nature enables daily environmental interactions, and a substantial body of evi-dence now demonstrates that nature contact generates extensive psychosocial, cognitive, and physicalhealth and well-being benefits. Estimates of the economic values of such benefits have lagged similarvaluation efforts for environmental services (such as improved air...

Criterion 6, indicator 33 : recovery or recycling of forest products as a percentage of total forest products consumption

This indicator shows the trend in recovering wood and paper for reuse in products in the United States. This reuse can hold down the need to harvest wood to meet U.S. consumption needs. The paper recycling rate (utilization rate in producing new paper) increased from 22% to 38% between 1970 and 1996, but then stabilized at 37% to 38% between 1996 and 2006. This rate...

Predicting the potential sensitivity of high elevation wilderness vegetation to changes in atmospheric chemistry - a strategy

A new strategy to estimate the sensitivity of alpine plant species to atmospheric deposition is presented. This approach utilizes plant physiological and morphological characteristics to estimate pollutant uptake. The plant characteristics can be determined quickly and easily in the field within the constraints of allowable activities in Class I wilderness areas....

Post-wildfire recovery of riparian vegetation during a period of water scarcity in the southwestern USA

Wildland fires occur with increasing frequency in southwestern riparian forests, yet little is known about the effects of fire on populations of native and exotic vegetation. From 2003 to 2006, we monitored recovering woody vegetation in wildfire sites in the bosque (riparian forest) along the Middle Rio Grande of central New Mexico, USA. To examine recovery potential...
