What is it about?

We conducted the first assessment of local experts’ ecological knowledge (local ecological knowledge, LEK) and remote sensing at a landscape scale. Our data cover more than 900 communities and nearly 4000 households in the Peruvian Amazon. We find strong concordance between LEK for the presence of tropical wild species (game, timber, and fish) and remotely sensed land cover as a proxy for species habitat.

Why is it important?

Our study demonstrates the promise of combining remote sensing and LEK for monitoring species status over large areas for biodiversity conservation and sustainable resource management in data-poor tropical forest areas.


Our Peruvian Amazon Rural Livelihoods and Poverty (PARLAP) project is the most extensive study as yet undertaken of rural communities and households in Amazonia. The large-scale LEK surveys in PARLAP allowed us to address the challenge of monitoring tropical wild species over large areas.
