Bioclimatology of Evergreen Sclerophyll Woodland.

Evergreen sclerophyll woodland (ESW) has been recognized as a zonal type of vegetation in the Mediterranean climate region. That region is characterized by winter rain and a hot, dry summer. As early as 50 years ago, Paul S.Martin documented the occurrence of ESW ("dry oak-pine woods") in the Sierra Madre Oriental of northeastern Mexico. More recently, in 1989, Leon de la Luz and Dominguez-Cadena described a stand of ESW on the Sierra de la Laguna, near La Paz, Baja California Sur. In these two northern Mexican weather stations, ESW thrives in a summer-rain climate regime. To determine if these Mexican stations were closely related phytosociologically to ESW in mediterranean-type climates, I sampled stands of ESW in California, on Sra. de la Laguna, in Arizona, Spain, Portugal and Turkey. In addition, I photographed stands of evergreen woodland (dry oak-pine) in Tamaulipas, Mexico and photographed evergreen forests (laurisylva) in three of the Canary Islands. Using principal components analysis, I created a dendrogram of all sampled stands. Further, using the H.P. Bailey system of bioclimatology, I analyzed the climates of stations near the sampled stands in Mexico, California and Mediterranean Basin. All of the ESW stands were phytosociologically related at the genus level and occurred in a climate characterized by H.P. Bailey as Mild, Temperate and Sub-Humid, despite differences in seasonality of the rainfall.
