Dendrocronología de Pseudotsuga menziesii (Mirb.) Franco de la Sierra Madre Oriental en Nuevo León, México

Tree-ring chronologies for Pseudotsuga menziesii were constructed for three sites of the Sierra Madre Oriental mountain range of the state of Nuevo Leon, Mexico: El Potosí, La Encantada and La Marta. The correlation coefficients between chronologies, the normality tests on the ring width, and an index of ring width indicate both, the climate regionalization and the decadence on diameter growth of Pseudotsuga menziesii (Mirb.) Franco populations. Potential subtle climatic changes may be contributing to the decline of radial growth of the three plant communities studied.
