Campaign-eligible species meet the following criteria:
- regularly occurring in Asean and outside marine habitats
- categorised as Critically Endangered or Endangered on the IUCN Red List
- known or likely to weigh at least 1 kg (because IUCN/SSC has identified that big animals (those over 1kg) in Southeast Asia are declining most rapidly and that without immediate action could disappear forever)
It should be noted that campaign species that meet the above criteria are not automatically eligible for project funding.
