The document discusses building a collaborative and participative biodiversity portal. It proposes crowd-sourcing biodiversity information by allowing users to create observations with location and species data. These observations would then be validated by other users and experts to enrich species pages and maps. The portal would include modules for species pages, maps, checklists, and observations. Data would be made openly accessible under Creative Commons licenses to build social networks and contribute to conservation science. Social groups would allow different levels of control over membership, postings, and validation. The goal is to harness collective intelligence and aggregate knowledge to better understand biodiversity.
