LifeCLEF 2020 brief overview

A brief overview (slides) was presented at ECIR 2020 conference.


Building accurate knowledge of the identity, the geographic distribution and the evolution of species is essential for a sustainable development of humanity, as well as for biodiversity conservation. However, the burden of the routine identification of plants and animals in the field 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 difficult task for professionals and naturalists. Bridging this gap is a key challenge towards enabling effective biodiversity monitoring systems. The LifeCLEF evaluation campaign aims at boosting and evaluating the advances in this domain since 2011. In particular, the 2020 edition proposes four data-oriented challenges related to the identification and prediction of biodiversity: (i) BirdCLEF 2020: bird species recognition in audio soundscapes, (ii) GeoLifeCLEF 2020: location-based prediction of species based on environmental and occurrence data, (iii) PlantCLEF 2020: a cross-domain image classification task aimed at identifying plants in pictures based on a training set of herbarium sheets, (iv) SnakeCLEF 2020: an image-based snake identification.


The winner of each of the four LifeCLEF 2020 challenges will be offered a cloud credit grants of 5k USD as part of Microsoft's AI for earth program.

Registration and data access

  1. Each participant has to register on AIcrowd ( with username, email and password. A representative team name should be used
    as username.
  2. In order to be compliant with the CLEF requirements, participants also have to fill in the following additional fields on their profile:
    • First name
    • Last name
    • Affiliation
    • Address
    • City
    • Country
  3. This information will not be publicly visible and will be exclusively used to contact you and to send the registration data to CLEF, which is the main organizer of all CLEF labs. Once set up, participants will have access to the dataset tab on the challenge's page. A LifeCLEF participant will be considered as registered for a task as soon as he/she has downloaded a file of the task's dataset via the dataset tab of the challenge.

CLEF Conference and working notes

CLEF 2020 CLEF Initiative

LifeCLEF lab is part of the Conference and Labs of the Evaluation Forum (CLEF). CLEF consists of independent peer-reviewed workshops on a broad range of challenges in the fields of multilingual and multimodal information access evaluation, and a set of benchmarking activities carried in various labs designed to test different aspects of mono and cross-language Information retrieval systems. More details can be found on the CLEF 2020 website.

Submitting a working note with the full description of the methods used in each run is mandatory. Any run that could not be reproduced thanks to its description in the working notes might be removed from the official publication of the results. Working notes are published within CEUR-WS proceedings, resulting in an assignment of an individual DOI (URN) and an indexing by many bibliography systems including DBLP. According to the CEUR-WS policies, a light review of the working notes will be conducted by LifeCLEF organizing committee to ensure quality. As an illustration, LifeCLEF 2019 working notes (task overviews and participant working notes) can be found within CLEF 2020 CEUR-WS proceedings.
