A BIOGEOGRAPHICAL INVESTIGATION OF THE SIERRA DE TUXTLA IN VERACRUZ, MEXICO.

Abstract

The Sierra de Tuxtla, a small, isolated volcanic mountain area near the Gulf coast of southern Veracruz, Mexico, affords excellent conditions for biogeographical investigations. The present study describes the manner in which physical and human factors have influenced native vegetation, nontransient avifauna and larger forest mammals in this tropical region. Physical factors considered are geology, land configuration, climate, drainage and soils; human factors examined include population, settlement and forms of land use. The Sierra has no major industrial raw materials, so agriculture continues to be the principal occupation, with commercial plantations providing export products. Although attempts are being made to improve agriculture and conserve forests, immediate and effective measures are required to control land use and enforce game laws. Varied natural habitats and a rich fauna provide excellent bases for a national park or wildlife refuge. Such an area would conserve forests, soils, water and wildlife, and afford a place for scientific study and recreation. A working man-land relationship must be established if the Sierra's natural resources are to be used wisely, its agricultural productivity increased and natural features preserved. (Author)
