Humpback whales are invading Sussex and Cornwall—why are they here?

In January 2025, a humpback whale was sighted off the coast of Deal, England, generating enthusiasm among wildlife enthusiasts and conservationists. The sighting was confirmed by a wildlife watcher who captured the moment on camera and reported it to the Kent Wildlife Trust (KWT). This incident coincides with increased marine activity along the British coastline, with additional reports of humpback whales appearing in areas such as Sussex and Cornwall. The KWT emphasized the importance of this sighting as it aligns with their ongoing efforts to monitor and protect marine mammal populations in the region. The humpback whale, classified as a species of 'least concern' by the International Union for Conservation of Nature, has experienced a rebounding population after nearly facing extinction due to commercial whaling practices in the 20th century. With an estimated global population of around 84,000 individuals, the success of conservation initiatives highlights the necessity of protecting these majestic creatures. Despite this recovery, the KWT aims to collect more data about individual whales, dolphins, and porpoises found in British waters to ensure their continued protection and understand their behaviors. Furthermore, the Kent Dolphin Project (KDP), which is part of the KWT's animal tracking program, is dedicated to tracking the movements of marine mammals in the area. Max Renton, a representative from the KDP, expressed the excitement surrounding the recent whale sighting, showcasing the significance of ongoing conservation efforts. The project conveys that while the whales may not be specifically tracked as the same individuals, the recent sightings emphasize the importance of understanding marine life behaviors. Concurrently, KWT has raised concerns regarding the implications of planned infrastructure, such as the proposed Sea Link undersea cable project developed by National Grid. The project aims to upgrade the electricity network to meet the UK government's clean power targets for 2030. However, critics advocate for reconsideration of the project due to potential threats to marine mammals. KWT's planning and policy officer noted that the current approach lacks adequate measures for wildlife protection. Meanwhile, National Grid maintains that they are actively collaborating with various environmental organizations and communities for feedback regarding the Sea Link project, aiming for a balance between renewable energy initiatives and wildlife safety.
