Guaiacum coulteri: an over-logged dry forest tree of Oaxaca, Mexico
Logging history and population structure of the dry forest tree species Guaiacum coulteri are described for Oaxaca, Mexico. We propose that the species has been adversely affected by selective logging, with large individuals now being uncommon. We argue that the species is likely to have undergone similar changes elsewhere in its range and, following IUCN guidelines, propose that it is categorized as Endangered. Maintenance of G. coulteri as an understorey shrub may be possible given current land use practices in the area but recovery of populations of large individuals may be more difficult. Suggestions for future research are made.(Received January 5 2004)
