Mike Heusner, steward of Belize’s waters, has died, aged 86

For a small country, Belize has long carried an outsized reputation among people who care about water. Its flats and mangroves, its reef and river systems, have drawn anglers and naturalists who come for beauty but stay, if they are paying attention, for the fragile bargain that keeps such places alive. Tourism can finance protection. It can also erode the very ecosystems it depends on. Few industries have to argue so often that their future rests on restraint.
That tension became sharper as Belize’s economy modernized and the pressures on its marine life grew more visible. The debate was never only about fish. It was about livelihoods, access, and who gets to decide what “development” means in a place where nature is not a backdrop but a working asset. The people who shaped that conversation were not always politicians or scientists. Some were business owners who spent enough time on the water to see what was changing, and who learned to speak in the language of policy when it mattered.
Michael J. “Mike” Heusner, who died on January 10th at 86, was one of them. For decades he was a leading figure in Belize’s tourism and sportfishing sectors and a steady advocate for conservation. He helped build Belize River Lodge into a premier destination for anglers, while pushing the idea that the country’s natural environment was not separate from its economy, but the condition of its survival.
Heusner’s authority came from lived experience and long committee meetings. He served with the Belize Audubon Society, tourism associations, and the Fisheries Advisory Board, and was known for explaining complex environmental issues through stories and practical examples. Oceana Belize, which named him an Ocean Hero in 2018, called him “a devoted advocate for the protection of Belize’s marine treasures” and noted his firm opposition to gillnets and other destructive fishing practices.
In 2009 he was a leading advocate for the protection of three sportfishing species, helping secure catch-and-release status for tarpon, permit, and bonefish. He argued that indiscriminate gear threatened biodiversity and the future of fishing-based tourism. He also worked to improve how guides and visiting anglers handled fish, treating technique as part of conservation, not an afterthought.
Heusner did not pretend that advocacy was glamorous. “Whatever I’ve done has been achieved through active participation in various organizations and committees,” he told Caribbean Lifestyle Belize. “I challenge the younger generations to get informed and involved in development issues. Work as an advocate rather than an activist. We need activists and we need advocates, who are after the same end result.”
