An analysis of the age-related decline in aboveground net primary production: Potential causes and stand-to global scale implications

Principal Investigators:

Stith T. Gower, and Ross McMurtrie

We propose to synthesize NPP data for forest age-sequence studies and use three ecosystem process-based models to determine the mechanisms(s) responsible for the age-related NPP decline for natural and plantation forests in contrasting climates. We will emphasize inter-ecosystem comparisons for a broad-range of forest biomes (tropical broad-leaved evergreen, sub-tropical broad-leaved evergreen, warm temperate needle-leaved evergreen, cold-temperate needle-leaved evergreen, broad-leaved evergreen, and broad-leaved deciduous and boreal needle-leaved... more

Application to GCTE

The Global Change and Terrestrial Ecosystems (GCTE) Core Research Project of IGBP maintains a portfolio of core research which is considered fundamental to current international research on global change impacts on terrestrial ecosystems. Each core research contribution is associated with one of GCTE's Core Research Projects. The DeCAF project has applied for recognition as GCTE core research within a Core Research Project entitled "Decline of Forest Productivity during Stand Development" under GCTE Activity 3.5 ("Effects of Global Change on Managed Forests").
