Spanish forest ecosystems' carbon emission will be higher than sequestration

3 March 2014

Spanish forest ecosystems will quite probably emit high quantities of carbon dioxide in the second half of the 21st century. This is the conclusion of a report that reviews the results obtained from the implementation of the forest simulation model GOTILWA+, a tool to simulate forest growth processes under several environmental conditions and to optimize Mediterranean forests management strategies in the context of climate change.

The report was published on the latest issue of the ecology and environment journal Ecosistemas, edited by the Spanish Association of Terrestrial Ecology. Peer review was led by professors Santiago Sabaté and Carlos Gracia, of the Department of Ecology at the University of Barcelona (UB) and the Centre for Ecological Research and Forestry Applications (CREAF), and the expert Daniel Nadal, of UB's former Department.

The study analyses data obtained from the simulation forest growth model GOTILWA+ (Growth Of Trees Is Limited by WAter), based on ecophysiological processes. The model enables to explore the effects of climate change on forestry ecosystems under changed environmental conditions and to simulate different management scenarios and compare them.
