Seabird protections drew debate at the annual meeting of the Commission for the Conservation of Southern Bluefin Tuna (CCSBT), held Oct. 5-8 in Brussels. The eight-member multilateral body that manages the stock has long struggled to curb seabird deaths caused by longline fishing targeting southern bluefin tuna (Thunnus maccoyii) across several oceans. This year’s meeting saw a modicum of progress on the issue. Based on recent modeling, the parties agreed on 13 priority seabird species for conservation efforts and designated high-risk areas for them. However, the designations don’t carry any new mandatory protections: Due to the reluctance of some members, the commission stopped short of adopting proposed conservation measures for the high-risk areas, most notably tighter seabird bycatch mitigation requirements. Oliver Yates, head of the marine program at BirdLife International, a U.K.-based NGO, told Mongabay that the identification of high-risk areas was “a good step forward” but said it was a problem that “they’ve not then adopted any management action to accompany the fishing activity in those spatial areas.” “[T]hey recognise bycatch of seabirds is a very serious issue but again agreed to do nothing about it,” Yates, who attended the Brussels meeting, added in a text message.

After decades of losses, new data show the world’s mangrove forests are beginning to rebound. It marks a modest but significant turnaround for the salt-tolerant coastal trees and shrubs, which provide vital ecosystem services, including carbon storage, habitat for thousands of species and protection from storms and erosion. Global mangrove cover increased by 477 square kilometers (184 square miles) between 1985 and 2025, according to the latest Global Mangrove Watch (GMW) data released in July. Restoration and stronger protections drove the modest net gains, which represent a 0.3% increase over four decades. The new assessment follows a separate study, published in June, that reached a similar conclusion about overall growth in mangrove cover. GMW, a mapping initiative of the NGO consortium known as the Global Mangrove Alliance, has tracked mangrove gains and losses since 2011. In this third update, researchers used 10-meter (33-foot) resolution satellite imagery and machine learning to map changes in mangrove cover across 108 countries. It’s the first of the updates to span a 39-year period, from 1985 to 2024, according to Lammert Hilarides, the GMW program lead at the Netherlands-based NGO Wetlands International. The previous version only tracked changes in the data since 1996, covering about 24 years. “The importance of tracking changes in mangroves lies in the need to have accurate information if you want to successfully halt loss, protect and restore mangroves,” Hilarides told Mongabay by email. He added that the new data show significant differences between regions, countries and the timing of gains…This article was originally published on Mongabay

Paul Spong’s life has been entwined with whales for nearly six decades. In the 1960s, Spong, who hails from Aotearoa New Zealand, moved to the U.S. to study physiological psychology at the Brain Research Institute at the University of California, Los Angeles. Then, in 1967, he entered the world of cetaceans when the Vancouver Aquarium in Canada hired him to study the behavior of a once-wild orca (Orcinus orca) named Skana, who’d been captured from Puget Sound that same year. While conducting behavioral, visual and auditory experiments on Skana, Spong quickly noticed the orca’s high intelligence and self-awareness, and advocated for her release. But the aquarium, which didn’t renew Spong’s contract, held onto Skana until her death in 1980. After his experience with Skana, Spong decided to investigate orcas in their natural habitat. In 1970, he landed on Hanson Island, off the northeastern coast of Vancouver Island, in British Columbia, Canada, with a tent and hydrophone, intending to study the local whales over the Northern Hemisphere summer. But his project stretched out longer than a single season, and by the late 1970s, Spong had founded a permanent research facility on Hanson Island, known today as the OrcaLab. Spong and his wife, whale researcher Helena Symonds, now serve as co-directors of the organization. Northern resident orcas near Hanson Island in British Columbia. Image courtesy of OrcaLab. Spong and Symonds made a conscious decision to take a hands-off approach, only observing the orcas using land-based hydrophones and cameras, rather than tracking them…This article was originally published on Mongabay
