Research

The Rio Bravo Conservation and Management Area has two facilities at Hill Bank and La Milpa, serving as centers for field based conservation initiatives. It has propelled Programme for Belize towards remarkable success and put Belize at the forefront of scientific research and conservation.

The Hill Bank Field Station, situated on the banks of the New River Lagoon, facilitates research activities to ensure the protection and wise management of the forest. It hosts primary projects such as the Forest Rehabilitation Programme and the newly established Freshwater/Aquatic Programme.

Located only three miles from the third largest archaeological site in Belize, the La Milpa Ecolodge and Research Center facilitates archaeological research though agreements with the University of Texas and Boston University. Through research carried on at and around the La Milpa Archaeological Site, Programme for Belize expects to learn more about how the ancient Maya civilization evolved, was organized and sustained, and why most of its centers eventually collapsed throughout the region.

Research within the borders of the Rio Bravo serves also to support a Contingency Planning Programme by clarifying the implications and potential impacts of economic development projects on the site. A planned road upgrade and test drilling for oil in the general area, for example, have the potential to increase pressure on Rio Bravo’s ecosystem. The degree to which they do so is highly dependent upon how they are implemented. In preparation for these potential scenarios, Programme for Belize must be in a position to help integrate developmental and environmental interests.

Chicle Production

The land of the RBCMA has historically been used by chicleros, who harvested the gummy sap of the sapodilla tree, commonly known as Chicle, for sale to the international chewing gum producers. Initially, trees had approximately 15 years to rest before a chiclero returned to harvest it.  As the demand for Chicle grew, chicleros returned more frequently to the trees and over-harvesting eventually diminished the population of sapodilla trees.  It is widely believed that this lack of sustainability was a primary factor in the decline of the market and the substitution of Chicle by other gums, both natural and artificial.

In its land use plan, PFB had mapped out blocks of forest for Chicle harvesting.  Some of these plots were dedicated to research to monitor the effects of harvesting on the sapodilla tree population and to determine an optimum rest period between harvests.  On the production plots, PFB expected to achieve a sustainable yield of approximately 2.5 – 5 tons of Chicle per annum.  The pilot project began in October 1993 and was completed in February 1994.  The Chicle produced was analyzed and determined to be of a high quality.  Market conditions however did not allow for the continuation of this project.

Horticulture

Preliminary investigations were done as to the possibility of growing orchids and house plants.  In the case of the orchids, micro-propagation could produce thousands of flowers annually without endangering the orchids in the wild.  Similar techniques were used to grow exotic house plants which have an immense international market.  It was determined that these horticultural projects could have the multiple benefits of generating income without endangering forest species, providing employment in the villages surrounding the RBCMA where jobs tend to be seasonal and primarily domestic for women, and replenishing impoverished plant populations countrywide.  Funding for this project was provided by the European Commission through World Land Trust.
