TRACE is the first-ever warming experiment to be conducted in a tropical forest. Our goal is to assess the effects of increased temperatures on tropical forest ecosystems.


The warming experiment officially started on September 28, 2016. After 1 year of warming 4degC above ambient temperatures, the warming experiment went through reconstruction due to the passing of Hurricanes Irma and Maria through Puerto Rico in September 2017.


We started the warming treatment again on September 26, 2018! 


Stay tuned for more updates!

TRACE is looking for a Project Manager, to manage the day-to-day research activities, work with the Principal Investigators for the project, collect data both in the laboratory and in the field, manage a site with high voltage electricity and a canopy access tower, coordinate with students, collaborators, and the USDA Forest Service International Institute of Tropical Forestry (IITF).

TRACE busca un Gerente de Proyecto, para manejar las actividades de investigación diarias, trabajar con las Investigadoras principales para el proyecto, colectar datos en el laboratorio y el campo, manejar un sitio de estudio con electricidad de alto voltaje y una torre de acceso al dosel, coordinar con estudiantes, colaboradores y el International Institute of Tropical Forestry del Servicio Forestal del USDA

About the project

Tropical forests take in and store more carbon dioxide than any other biome around the world, but climate change may pose a threat to this invaluable service. Scientists from various governmental agencies and universities are working together to measure the potential impacts of climate change- particularly temperature increase- on soil structure, carbon cycling, and plant physiology. The TRACE experiment consists of using infrared heat to warm the soil and plants of the understory, as well as individual leaves and branches in the forest canopy. 

On this website, you can learn about our project and join us in our efforts to better understand how tropical rainforests will behave in a warmer future. This experiment will help improve conservation strategies for these irreplaceable ecosystems and all the biodiversity and natural resources they sustain.
