(August 2023) Study “Afforestation efforts for golden-winged warblers and other forest-associated species in Honduras” published in the Spanish academic journal “Sociedad de Ornitología Neotropical”. Study validates earlier findings that IOC farms provide much-needed habitat for the warblers not found in other coffee farming scenarios. (Results that were originally demonstrated in Costa Rica and confirmed by Murillo’s study in Honduras)

(2021) Study, “Generating Best Management Practices for Bird and Forest Conservation” published in Springer Nature journal. Research-based recommendations for the application of land-sparing coffee production designed to conserve forest-dependent wildlife. (i.e. Integrated Open Canopy™).

Authors: Jeffrey D. Ritterson, David I. King, Raul Raudales, Richard Trubey, and Richard B. Chandler.

(2013) Study, “A Small-Scale Land-Sparing Approach to Conserving Biological Diversity in Tropical Agricultural Landscapes” published in Conservation Biology journal. Examines land-sharing models of forest conservation vs. land-sparing models, by analyzing and comparing bird population studies on shade coffee farms (land-sharing) with Integrated Open Canopy™ (IOC™) coffee farms (lands-sparing).

Authors: Richard B. Chandler, David I. King, Raul Raudales, Richard Trubey, Carlin Chandler, and Víctor Julio Chávez Arce.

(2009) Study, “Measuring the Environmental Costs of Coffee Production” published in Conservation & Society journal. Examines coffee’s global environmental impacts, including: energy, water, and land use, as well as loss of forest. Particular attention is paid to the unsustainable use of forest wood being as a main source of energy for processing coffee in Central America.
