The Lead Pointing to a photograph of dry brown long grass hugging the shoreline, Gerardo Bolaños stands in front of a green oasis of seedlings and trees potted in black plastic bags. "This is what Playa Guiones looked like when we started in 2011," says the executive director of Costas Verdes, a Costa Rican nonprofit. The Coastal Transformation As howler monkeys growl in the background, Bolaños points to the picture next to it – an image of the same patch of land but with scores of flourishing, lush green trees. Today, he says, this is how the beach looks. The reason for the stark difference, says Bolaños, a straight-talking man with a coloured tattoo of the turquoise-browed motmot bird on his left arm, is a sustained tree-planting programme that Costas Verdes started in 2011. The Roots of Reforestation Costas Verdes was founded by then Costa Rican university student Max Tattenbach in 2009. A keen surfer, he wanted to restore the shoreline at his favourite surf spot, Playa Hermosa. "Playa Hermosa is about 6km [3.5 miles] of beach, and it only had one [area of] shade along the entire beach," says Tattenbach. "I used to go surfing there and take my then girlfriend and now wife. She didn't surf and liked to read and chill on the beach, but Playa Hermosa had no shade, so she didn't like going, and it started to become an issue. I promised her I would reforest Playa Hermosa so we could enjoy the beach." The Environmental Impact The project has transformed deforested Pacific coastlines into thriving ecosystems through a community-driven environmental project that has planted more than 100,000 native trees across 34 beaches, reviving wildlife habitats and combating decades of deforestation from cattle farming. Walk along the seafront in Nosara, over 100km further down the coast from Hermosa, and the plan appears to have paid off, with thousands of trees such as tropical almond trees, madero negro (Gliricidia sepium) and frangipani lining the trails and offering shade to beachgoers, creating a thriving ecosystem for wildlife. The Historical Context of Deforestation Bolaños, who joined the organisation as a volunteer in 2011, became project director three years later and executive director in 2024, says deforestation has changed the area's landscape. "Last century, we had great coastal forests all along the Pacific coast of Costa Rica," he says. Bolaños estimates that between the 1940s and 1970s, Costa Rica lost 70% of its forest cover, including along the Pacific coast. He puts this down to a boom in livestock farming. "Farmers burned the ecosystems and grew grass to feed the cattle. It was extremely aggressive, poorly planned," he says. "The beachfronts were devastated by cattle farming." The Future of Coastal Restoration What began as a personal quest for shade has evolved into a community-driven environmental movement with significant implications for coastal conservation. The success of Costas Verdes demonstrates how small-scale, community-led initiatives can have a substantial impact on environmental restoration, offering a model for other regions facing similar deforestation challenges. As climate change continues to threaten coastal ecosystems worldwide, the reforestation efforts in Costa Rica provide a hopeful example of how human intervention can help restore natural habitats and build resilience against environmental degradation.

The Lead 'A noisy river is a healthy river,' says Ruth Needham of the Trent Rivers Trust (TRT). The Mease in the Midlands must be in fine fettle, then, as it gurgles merrily along. Sunlight glints off riffles in the water and shoals of fry dart past. Needham has good reason to be buoyant - last month, the Mease won the UK River prize 2026 in recognition of the trust's 13-year restoration campaign. The Restoration Journey The sad state of Britain's rivers is common knowledge, partly thanks to recent media coverage highlighting the sewage crisis. The Mease is a case in point - a 27km lowland river that rises in Leicestershire and flows into the River Trent. For too long, water has been seen as a problem to be controlled: drain it, dredge it, get it away. Over the past 150 years, drainage ditches have been engineered along the Mease, its banks shored up, its flow controlled with weirs. The Environmental Impact This alteration of the river had catastrophic consequences. Soil, silt and sediment got washed from fields straight into the river, causing high levels of phosphate that led to algal bloom and decreased oxygen levels. The fish population struggled, including two rare species that make the Mease a designated site of special scientific interest (SSSI): the spined loach and European bullhead. Other wildlife declined too, as there were no natural water channels with a mix of habitats to support different species. The Collaborative Solution In 2013, a restoration project began, led by the TRT and largely funded by the Environment Agency (EA). "We wanted to change the status quo, force the issue and get people to work together," Needham says. The biggest challenge was getting farmers on board - they were effectively being asked to give up land, leaving buffer strips for water and wildlife. It took time to build trust and to apply for compensation under government environmental land management schemes. The Future Outlook "The prize has been a massive boost," says Needham. "If we can get the Mease into better condition, we can improve other rivers, too." The restoration of the Mease demonstrates that with proper collaboration, innovative approaches, and long-term commitment, even severely degraded rivers can be brought back to health. This success story offers hope and a blueprint for river restoration efforts across the UK and beyond.
