Process-Based Models to Determine Potential Forest Productivity and Resource Use Efficiency

The FPC has worked with process-based models to determine the potential productivity of pine and eucalyptus plantations in both the S.E. United States and in Latin America.  These models enable us to develop a better understanding of soil and climatic related factors affecting forest productivity.

Potential productivity for Pinus taeda in the southeastern USA (a) and Eucalyptus spp. in Colombia (b) estimated using 3PG applied at the landscape scale assuming a maximum leaf area index to estimate potential productivity (Rubilar et al., 2018).

Detailed results from trials across climates and soils provide data for parameterization and validation of these models.
