* Development of the first fish-based indices of biotic integrity (IBI) to be consistently applied in the humid tropics.
* Subsequent development of the first visual index of biotic integrity (IBIVI) permitting evaluation of fish assemblages without costly gear.
* Adaptation of the USDA Stream Visual Assessment Protocol (SVAP) for our humid tropical region.
* Application over 17 years of fish, benthic macroinvertebrate and physical habitat-based monitoring leading to countless ecological assessments at (so far) 202 sites in the La Amistad Caribe region.
MAPA DE SITIOS
* Development of one of the tropical world's largest stream bioassessment databases.
* Inventories of aquatic fauna throughout the La Amistad Caribe region, including contributions to the description of new species.
* Training of a cadre of some 20 indigenous "bioeducators" capacitated to carry out independent bioassessments and apply the results.
* Leadership role, together with the bioeducators, in the campaign to prevent indiscriminate damming of streams draining the La Amistad World Heritage Site and to oppose open pit metals mining in the area.
* Development and implementation of an aquatics component in an Environmental Education project overseen by the Talamanca/Caribbean Biological Corridor Commission in the schools of the La Amistad region, with plans for extension into Panama.
* Complete inventory of sources of environmental contamination in the binational Sixaola River watershed, with recommendations for prevention, restoration and mitigation.
* Biological health assessment of streams draining the La Amistad National Park in Costa Rica.
* External consultancies in areas such as Costa Rica's Madre de Dios watershed and the Azuero Peninsula of Panama, in conjunction with national governments and local institutions.
* Bioassessment reports on particular components of the La Amistad Caribe watersheds - binational Rio Yorkin watershed, Gandoca/Manzanillo National Wildlife Refuge, Hone Creek watershed, etc.
* Pilot scale stream restoration at several sites, with emphasis on riparian reforestation.
* Ongoing collaboration in an international campaign to determine the genetic identity of stocks of endangered American eel in the Gulf of Mexico and Caribbean.
