On March 14, 2010 the Eastern Native Tree Society and Western Native Tree Society switched from discussion lists on Google Groups to a new discussion list in a Bulletin Board format at: http://www.ents-bbs.org/index.php   Posts made since the inception of the BBS on March 14, 2010 will be sorted and archived on the BBS. Click on the link to go to the equivalent section on the new BBS. This website will continue to serve as a front end for the ENTS and WNTS groups. It will continue to serve as a repository of older posts, and will serve as the host site for special projects and features that are not well suited for a BBS format. Please visit the BBS for the latest information and trip reports.

  • Caribbean National Forest http://www.fs.fed.us/r8/caribbean/ 

    Located on the Caribbean Island of Puerto Rico in the Greater Antilles group, the Caribbean National Forest is the sole tropical rain forest in the U.S. National Forest System. The forest’s relatively small 28, 000 acre size belies its importance. It differs significantly from all the other U.S. National Forests because of its year-round tropical climate and immense biodiversity.

    The rugged Luquillo Mountains that rise to 3,533 ft. above sea level comprise most of the forest land. Their steep slopes can sometimes receive rainfall of over 200 inches (508 centimeters) at higher elevations! Caressed by gentle easterly winds the forest has an average temperature of 73° F (21° C), and seasonal changes are almost imperceptible. It is the ideal climate for exuberant tropical vegetation. The rain forest is noted for its biodiversity; it is “home” to thousands of native plants including 150 fern species, 240 tree species (88 of these are endemic or rare and 23 are exclusively found in this forest). The Caribbean National Forest has no large wildlife species, but hundreds of smaller animals abound in this gentle forest, many of which exist nowhere else on the planet!!

  •  LUQUILLO EXPERIMENTAL FOREST LONG-TERM ECOLOGICAL RESEARCH PROJECT http://luq.lternet.edu/ Overview of the research project:: The Luquillo Experimental Forest Long-Term Ecological Research (LUQ) program is located in the Luquillo Mountains of eastern Puerto Rico. LUQ is part of a network of Long-term Ecological Research (LTER) programs in the United States (funded by the US National Science Foundation) and elsewhere, all of which address core research questions in the context of local research goals. The main goal of LUQ studies is to understand the long-term dynamics of tropical forest ecosystems characterized by large-scale, infrequent disturbance, rapid processing of organic material, and high habitat and species diversity.
