Aldabra study estimates about 183,000 giant tortoises

A study estimates roughly 183,000 adult and subadult giant tortoises on Seychelles’ Aldabra Atoll, Good News Network reports. Researchers modeled monitoring data to account for animals missed in dense vegetation and found a broadly stable population during 2018–2021. This improves the counting baseline rather than showing a sudden population surge; drought and invasive mammals remain threats.
