Cerrado-Amazonia Transition - Brazil
Parent Site Name
carbon and nutrient cycling
The LTER-TRAN site is located in the transition between the Cerrado and Amazonia biomes, in a region called "arc of deforestation", that suffers strong impacts by the agriculture expansion. The site include 10 subsites (Bacaba, Vera Cruz, Tanguro, Santa Marta, Floresta, Araguaia, Santana, Serra das Araras, Guaporé and Tangará), in five municipalities of Mato Grosso and Pará states. The base-site is located at the Bacaba Municipal Park, in eastern Mato Grosso, where areas are being monitored since 1996, to evaluate the temporal and spatial changes of the vegetation (forests and savannas) and streams, allowing to understand the natural dynamic processes and the changes resulting from human actions. Legal reserves areas in farms and flooded forests of the Araguaia State Park are also being monitored. Social-environmental studies and intensive educational actions complement the activities of this site.
General Characteristics, Purpose, History
1. Helping Amazonian researchers to build a collaborative network fit for purpose for monitoring biomass dynamics, carbon, and biodiversity on-the-ground across Mato Grosso and beyond in Brazil. 2. Provide a quantitative assessment of biodiversity, tree conditions, functional traits, carbon storage, liana infestation, tree growth and dynamics across 50 Southern Amazonia plots. 3. Estimate the carbon balance of forests in Mato Grosso and Pará (ca. 1996 – 2017). 4. Evaluate the effects of recent droughts (e.g. 2010 and 2016), fires and deforestation on biomass carbon balance, dynamics, functional traits and biodiversity of southern Amazonia plots. 5. Evaluate the effects of deforestation and land use on physical and chemical water properties and on diversity and structure of aquatic insects and mammals populations.
