The botanical and floral diversity of the Bay Islands, Honduras, has received little scientific attention. The team from Kanahau, with the help of botany expert Dr, Sven Batke of Edge Hill University, UK, report an additional locality for the mycoheterotrophic species Voyria aphylla (Jacq.) Pers. (Gentianaceae), from within mixed swamp forest and neotropical savannah habitat on the island of Utila.
Please find below a chronological list of Kanahau's scientific output dating from 2012 - until present, that has been published after peer-review in reputable and relevant scientific journals. Our research index consists of the article references complete with title-click links to the open-access online publications. This list is regularly updated with new publications from our research, so stay tuned!

Grants and Funding
A Little Help Goes a Long Way
As a non-profit NGO, Kanahau and its researchers owe great thanks to various funding bodies for their financial support. We do not have fancy facilities, marketing offices, or high-paid staff salaries, instead our non-profit business model injects funding straight back into conservation research activities. Without successful grant applications and interns, our biodiversity research and study of threatened species on Utila would cease to be possible. External funding is often sought to conduct species specific projects, with finances dedicated to covering logistical and costs of active species research, population monitoring and conservation action. External funding is also essential to run and maintain our facility, provide alternative incomes to our local staff, generate community initiatives/workshops and purchase new equipment which can improve our efficiency and output!

December 2015 - Daisy F. Maryon and David C. Lee
We thank IIF for funding our new research in 2016
A growing legacy
Over the years, our efforts on Utila have earned us the reputation of being the most scientifically active and research-orientated conservation NGO on the island, and we seek to maintain this by continuing to fund, develop, communicate and publish the results of new studies. Kanahau couldn’t have reached these milestones without an incredible team of volunteers, students and staff. We are honored to support researchers in the pursuit of biological knowledge, and could not be happier to pursue what it is we love and consider to be our mission in life - to better understand, appreciate and protect our natural world.
