Board of Directors

Vanessa Kilburn, Chairperson

For the past 15 years, Vanessa Kilburn has been active in the field of conservation biology with a focus on herpetology both in North America and in Central America. Throughout her career she has gained extensive experience in field methodology techniques used for fish, amphibians, reptiles, birds, and mammals. Vanessa has designed and conducted habitat assessments and habitat characterization work in various temperate and tropical habitats, in particular wetlands, lakes, and streams.

Prior to moving to Belize and establishing T.R.E.E.S and its field station, she lead Endangered species recovery programs in British Columbia and in the Dominican Republic, which included scientific research, hands-on habitat restoration, and public outreach and education. As a result of these efforts Vanessa has gained experience working with all levels of government, non-government organizations, the private sector, industry, academia, and the general public. She holds a B.Sc. Honours in biology from the University of New Brunswick and an M.Sc. in conservation biology from McGill University. She is currently the Program Manager for T.R.E.E.S and is responsible for designing the activities and programs offered at the center, in addition to conducting her own research on herpetofauna in the Maya Mountains.


Mathieu Charette, Executive Director

Mathieu is a wildlife biologist with over 20 years of experience in the field, both in North America and internationally. His extensive experience has allowed him to acquire expertise on a multitude of species in all animal groups and in various habitat types. He has also worked extensively with the academia, NGOs, numerous government agencies and the private sector on research, conservation, restoration, and development projects. This experience has given him the expertise to assess the needs of different types of stakeholders and communities and to merge them with the requirements of critical habitat and the target species. He holds a B.Sc. in wildlife biology from McGill University and an M.Sc. in wildlife conservation from the University of New Brunswick. He is currently the Operations Manager and Scientific Coordinator at T.R.E.E.S.


Daisy Flamenco, Secretary


Denver Cayetano, Councillor

Denver is a Belizean ecologist, self-proclaimed “bushy” and no stranger to T.R.E.E.S, having worked as an internship coordinator supervising botanical/forestry interns. He completed his undergraduate degree in Natural Resources Management at the University of Belize where he was subsequently employed as a Forest Biologist at its Environmental Research Institute. Since then, Denver has furthered his education in Germany where he graduated with his master’s degree in Forest Sciences and Forest Ecology from the University of Göttingen. He is currently working towards his Ph.D. in Forest Resources and Conservation at the University of Florida. Denver described his interests as being “very broad” but centered around sustainable forest management, carbon cycling and sequestration, disturbance ecology and building youth capacity for research in Belize.


Elliot Handrus, Councillor

Eliot was born and raised in San Diego, CA. Upon graduating high school he attended SDSU where he received a Bachelors in Zoology. Soon after, he started working as a mammal keeper at the San Diego Wild Animal Park in 1985. He received a Master’s Degree at SDSU in biology in 1988. He continued working as a keeper until 2000 when he became the Population Biologist. These duties included managing populations genetically and demographically; both for the San Diego Zoo collections as well as on a world wide or regional basis. This allowed him to participate in re-introduction programs in various parts of the world, and advise others on how to manage populations. After this, he headed to the Fort Worth Zoo as a lead keeper, then to Mountain View in Fort Langley, BC as curator. He left after a year to return to San Diego, where he worked in biotechnology until 2013. He then started his third career as a community college professor teaching biology, environmental science, ecology and conservation biology, which he continues to enjoy. He currently lives in Corozal with his wife.


Gliselle Marin, Councillor

Gliselle Marin was born in Belize. Her biological career began with a foundation in herpetological research where she worked for 2 years at the Purdue University Herpetology lab. Gliselle continued her research interests as the Research Coordinator at the Texas Christian University where she worked on a joint research project with Nextera Wind Farms. She spent 6 months volunteering as a field assistant on the Manu Bird Project, looking at the effects of climate change on birds at various elevational gradients in Peru. Gliselle received a Master of Conservation Biology from Victoria University of Wellington in New Zealand.

She returned home to Belize and has worked with the Ya’axche Conservation Trust, an organization working toward integrating climate-smart farming methods within the Indigenous Mayan communities of southern Belize. She previously worked as the Maya Forest Corridor Officer at the University of Belize Environmental Research Institute. Gliselle is excited to be a part of the long-term monitoring and research at T.R.E.E.S. for bats, herps and birds and looks forward to working with students and interns of all ages toward the conservation of Belizean species.
