In view of the expanding market and the uncertainty<br />
of the present resources of the small<br />
number of timbers being utilized, the need for<br />
using the lesser known species is of first importance.<br />
This applies both to the areas having abundant<br />
timber supplies and to the islands having<br />
insufficient forest, reserves, yet many unused<br />
timbers.<br />
Lack of knowledge, particularly by the consumer,<br />
seems the principal deterrent to the utilization<br />
of lesser known woods. Needed is informat<br />
ion on physical and mechanical properties, as well<br />
as knowledge of air seasoning, kiln drying, durability,<br />
machining characteristics, and resistance to<br />
insects and marine organisms. Prospective users<br />
should also have the benefit of reliable recommendations<br />
on the acceptable uses for the different<br />
timbers and an estimate of their present and potential<br />
availability.<br />
In view of the above considerations, the Fourth<br />
Session of the West Indian Conference held in<br />
1950 recommended that a future conference be<br />
convened to consider the agricultural potentialities<br />
of the Caribbean area, with special reference<br />
to developing the timber trade. Later, the objective<br />
was restricted to a study of the present and<br />
potential timber trade. The conference, held at<br />
Port of Spain, Trinidad, in April 1953, was attended<br />
by representatives from most countries and<br />
islands of the Caribbean area.<br />
Conference delegates agreed on the need for<br />
compiling and publishing a list of the timbers of<br />
present and potential regional importance. They<br />
also agreed that this document should cover the<br />
entire Caribbean, including the independent republics,<br />
and should contain all available information<br />
on the selected timbers. The principal timbers<br />
described in the text were selected largely<br />
by member countries of the Caribbean Commission<br />
and do not necessarily include all timbers of<br />
present or potential importance in the entire<br />
Caribbean region.<br />
Countries represented in the selection of timbers<br />
are as follows: British Guiana, French Guiana,<br />
Surinam, and British Honduras on the<br />
continent; Jamaica, Dominican Republic, and<br />
Puerto Rico in the Greater Antilles; Guadeloupe,<br />
Dominica, Martinique, St. Lucia, St. Vincent,<br />
Grenada, Trinidad, and Tobago in the Lesser Antilles.<br />
Although Cuba and Haiti are not included<br />
in this group, they are well represented by the<br />
selections made for other islands in the Greater<br />
Antilles. But important timbers in other parts<br />
of the Caribbean area are not discussed in detail<br />
unless they are also presently or potentially important<br />
in the above countries or islands.<br />
The conference by resolution directed the<br />
Secretariat of the Caribbean Commission to ask<br />
the Tropical Forest Research Center of the U.S.<br />
Forest Service for assistance in the project. In<br />
answer to that request., this publication was prepared.<br />
It presents, to the best of the author’s<br />
knowledge, a summary of all available and worthwhile<br />
information on the 71 important timbers in<br />
that part of the Caribbean area described above.<br />
SELECTION OF IMPORTANT<br />
CARIBBEAN TIMBERS<br />
Foresters and other representatives of the Government<br />
attending the 1953 Timber Conference in<br />
Port of Spain, Trinidad, selected an initial list of<br />
54 timbers of present or potential commercial importance.<br />
The number was later increased to 71<br />
as additional timbers were suggested. This number<br />
will surely increase in the years ahead : Remote<br />
areas will become more accessible to improved markets,<br />
and further studies will be made of the<br />
quantity and quality of many woods, currently<br />
little known. The final selection of timbers covered<br />
in this work and the species chosen are essentially<br />
as suggested by the participating<br />
governments. The timbers are listed by their preferred<br />
trade and botanical names in table 1.<br />
