ABC Expeditions


A project funded by the Research Council of Norway

and led by the Norwegian University of Life Sciences (NMBU)

Our objective:

The ABC expeditions combine vegetation inventories and multi-taxa wildlife surveys to assess biodiversity and carbon stocks in undersampled regions across the Brazilian Amazon.

Comprehensive field surveys

Our ABC expeditions will enable us to:

  • Provide distribution data for multiple plant and animal taxa in remote undisturbed forests.

  • Assess the biogeography of biodiversity patterns across Amazonian interfluvial regions.

  • Compare the effectiveness of traditional and modern survey techniques.

  • Demonstrate the value of comprehensive and standardised rapid biodiversity assessments.


  • Improve estimates of aboveground biomass and carbon stocks across Amazonian-wide climatic gradients.

  • Assess how aboveground biomass and carbon stocks relate to patterns of biodiversity in remote undisturbed forests.

Cutting-edge analyses

Surveying areas previously covered by the RadamBrasil project conducted by the Brazilian government in the 1970s, we will also be able to:

  • Compare our carbon stock estimates to those from 50 years ago.

  • Use network analyses to model the potential impacts of overhunting on carbon stocks.
