Impacts of Climate Change on Pacific Northwest Conifers

September 2011
CO2 Science;9/21/2011, Vol. 14 Issue 38, p5
The article discusses a study on growth-climate relationships for six conifer species made up of three high-elevation species and three low-elevation species which occupy contrasting altitudinal ranges on Mt. Rainier in Washington, U.S.A. Ninety years of annual tree growth data were collected from over 600 individual trees growing at nine different elevations. It concludes that biotic interactions can be strong in closed-canopy forests which may constrain performance more than climate.

    Tropical forests play a crucial role in regulating regional and global climate dynamics, and model projections suggest that rapid climate change may result in forest dieback or savannization. However, these predictions are largely based on results from leaf-level studies. How tropical forests...

    Warming and drought pose a serious threat to tropical forest. Yet the extent of this threat is uncertain, given the lack of methods to evaluate the forest tree cover changes under future climate predicted by complex dynamic vegetation models. Here we develop an empirical approach based on the...

    There is strong evidence that climate change alters tree growth in boreal forests. In Estonia, the analysis of ring measurements has been a common method to study growth changes.
