Résumé

Building accurate knowledge of the identity, the geographic distribution and the evolution of living species is essential for a sustainable development of humanity, as well as for biodiversity conservation. However, the burden of the routine identication of plants and animals in the eld is strongly penalizing the aggregation of new data and knowledge. Identifying and naming living plants or animals is actually almost impossible for the general public and often a dicult task for professionals and naturalists. Bridging this gap is a key challenge towards enabling eective biodiversity information retrieval systems. The LifeCLEF evaluation campaign, presented in this paper, aims at boosting and evaluating the advances in this domain since 2011. In particular, the 2019 edition proposes three data-oriented challenges related to the identication and prediction of biodiversity: (i) an image-based plant identication challenge, (ii) a bird sounds identication challenge and (iii) a location-based species prediction challenge based on spatial occurrence data and environmental tensors.
