  • Turning oil platforms into reefs

    After oil and gas platforms reach the end of their working lives, some are being turned into artificial reefs that can create new ecosystems in the ocean. Since the 1980s, 550 platforms have been reefed in the Gulf of Mexico and programs are springing up to help industry make the switch. These reefs can be home to fish and birds, and studies have shown that some species prefer these structures over their natural habitats. While not all environmentalists agree with leaving the platforms in the water, scientists are working to understanding how similar programs can be implemented in other parts of the world.

  • The long shot that saved Belize's coral

    After a hurricane hit the coast of Belize in 2001, it essentially destroyed the coral reefs in Laughing Bird Caye National Park. Lisa Carne wanted to start transplanting coral to regrow the reefs, but it took five years to secure funding to start her project. Restoring coral reefs is a lot of effort, so she founded a nonprofit called Fragments of Hope that hired local residents to help. Because of her efforts, over 85,000 corals have been planted and 89 percent of them survived after 14 years, The techniques used are being applied in other countries like Colombia, Jamaica, and St. Barts.

  • How Kenya turned the tide against ivory poachers

    More and more park rangers, judges, prosecutors, and wildlife investigators are working together to stop poaching in Kenya. Through training and a new app that allows all parties to track wild animals in a protected conservation area, the number of poaching cases has decreased from 449 creatures killed illegally in 2021 to 93 in 2018. The number of court cases have also decreased in recent years.

  • The detection dogs tracking poachers and Covid-19

    Detection dogs and their handlers can be trained to sniff out any number of problems. In eastern Africa, the Canines for Conservation project has deployed dogs to search for poachers and illegally harvested wildlife products. By tracking poachers from the scenes of illegal kills and finding ivory and rhino horns stashed in warehouses and shipping containers far more efficiently than X-ray methods, the project has contributed to nearly 400 product seizures, higher conviction rates, and elimination of elephant poaching in parts of Kenya. The next frontier being tested: detecting COVID-19 infections.

  • The fight to save India's most elusive cat

    After a fishing cat was first documented in an Indian coastal city, state authorities, scientists, and conservationists sought to understand how many felines called the wetland home. Using camera traps, they observed 10 individual fishing cats among the mangrove forests, though this method of estimating the population is tricky. Another survey is underway as researchers study how the health of these habitats are linked to the health of the fishing cats, and how to effectively educate locals about the importance of protecting this species.

  • How Scientists Are Pivoting In Their Quest To Save Hawaii's Crows

    After a five-year effort to reintroduce the alala bird on Hawaii’s Big Island failed, conservationists are looking into releasing the nearly extinct Hawaiian crow on a different island. Of the 30 birds released in 2016, only five survived. Another predator known as the Hawaiian hawk killed off some of the birds. Releasing the crows on Maui is a temporary solution, but could allow them to learn skills to survive with other predators.

  • The Return of the Polish Wolf

    Scientists, NGOs, conservationists, and the government worked together to bring the Polish wolf back from the brink of extinction. Methods like GPS tracking and genetic sampling have helped politicians made decisions about how to reduce human-animal conflict and ensure human development didn’t interfere with their habitats. As a result, over the last 50 years the wolf population in Poland has increased 50-fold.

  • Helping animals cross the road and other obstacles

    As human infrastructure continues to threaten animal habitats, researchers are coming up with ways to use artificial structures as bridges for these creatures to get where they need to go. In Indonesia, irrigation pipes help farmers water their crops, but they’re also used by slow lorises to cross over the farmlands. In Brazil, a bridge crossing a major highway will be used by golden lion tamarins to avoid the busy traffic.

  • 'Virtual rangers' help South African reserve keep poachers away

    Over 55,000 people have become “virtual rangers,” helping to protect South Africa’s Balule Nature Reserve from poachers. Officials at the reserve teamed up with Samsung and Africam to increase the ability to keep watch over the park, which is home to some of the most vulnerable animals to poaching, including rhinoceros, leopards, and elephants. Camera phones, held in protective cases, are mounted around the reserve and stream images to “virtual rangers” worldwide who have already reported hearing gunshots, which could indicate the possibility of poachers, and seeing trapped animals needing rescue.

  • Simple hand-built structures can help streams survive wildfires and drought

    Conservationists, government agencies, scientists, and landowners are working together to restore streams using low-cost solutions from sticks, stones, and even beavers. Restoring these floodplains is important to help communities combat drought and wildfires. In Idaho, scientists relocated nine beavers to Birch Creek so they could help repair the dried-up stream. In three years, the beavers built dams, which helped the creek flow for longer in the summer. This method might not work everywhere, so scientists have also tested stone structures, which also proved effective at improving the ecosystem.
