LifeCLEF 2015: Call for participation

The lab of CLEF dedicated to the recognition of living species.

  • BirdCLEF: an audio record-based bird identification task (1000 species)
  • PlantCLEF: an image-based plant identification task (1000 species)
  • FishCLEF: a fish video monitoring task (9000 fish instances)


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. In this context, using multimedia identification tools is considered as one of the most promising solution to help bridging the taxonomic gap. With the recent advances in digital devices/equipment, network bandwidth and information storage capacities, the production of multimedia data has indeed become an easy task. In parallel, the emergence of citizen sciences and social networking tools has fostered the creation of large and structured communities of nature observers (e.g. e-bird, Xeno-canto, Tela Botanica, etc.) who started to produce outstanding collections of multimedia records. Unfortunately, the performance of the state-of-the-art multimedia analysis techniques on such data is still not well understood and far from reaching the real world’s requirements in terms of identification tools. The LifeCLEF lab proposes to evaluate these challenges around 3 tasks related to fine-grained classification problems in three living worlds. Each task is based on large and real-world data and the measured challenges are defined in collaboration with biologists and environmental stakeholders in order to reflect realistic usage scenarios.


BirdCLEF: an audio record-based bird identification task

  • data collected by Xeno-canto social network
  • 1000 bird species from South America
  • around 33k audio records

PlantCLEF: an image-based plant identification task

  • data collected by Tela Botanica & Pl@ntNet's social networks
  • 1000 plant species from West Europe
  • around 113k images 

FishCLEF: a fish video monitoring task

  • Underwater cameras
  • 15 fish species living in coral reefs
  • around 9000 fish instances localized in 20 videos + 20,000 sample images
