Saving Green Giants in the Forests of Lousada

At Expo Amazonica in Lima, chefs are working to build a taste for traditional Amazonian foods, in an effort to promote biodiversity conservation and slow deforestation. But against a huge global demand for palm oil, growing wild food crops can be difficult for communities struggling to make ends meet. One big question is whether small farmers can create demand for Amazonian cuisine beyond the Amazon?

The Wall of Trees initiative in Nigeria's Makoda village created a four-tiered barrier of windbreak, orchard, woodlot, and economic trees that tripled crop yields and provided income opportunities for 200 women, successfully reversing desertification on 15 hectares over two decades.

The United States National Park Service is planting giant sequoia tree seedlings in groves that were decimated by extreme wildfires in Sequoia and Kings Canyon National Parks. The effort aims to preserve the endangered species as the organization doesn’t believe the trees in these areas will regenerate on their own.

Conservation efforts in Australia are saving the Wollemi pine tree from extinction. The Wollemi Pine Recovery Team works with a variety of experts to study and repopulate the plant while saving the remaining wild pines from disease and fire. The team also gets some help from the public who buy pines to care for at home.

Sacred groves in India protected by religious practices, culture, and communities are helping country-wide conservation efforts for greenery and endangered species.

The Miyawaki method of planting miniature natural forests in cities as a way to reduce air pollution and cool down temperatures is gaining ground throughout the world. The process involves planting a variety of trees in a particular way that allows for them to grow rapidly. While this method is very labor intensive and can be difficult to scale, there are more than 1,500 of these types of forests in Japan, India, and Pakistan.

A public-private scheme between the Seychelles Islands Foundation and a government agency is allowing residents to plant seeds of the coco de mer, or sea coconut, as a way to save the endangered tree species. So far, 96 seeds have been planted on 26 properties. Despite its extremely slow growth rate, island residents are excited to grow trees for future generations and protect them from poachers.

Landowners, state employees, environmental groups, and local hunters are working together to protect Hawaii’s forests and drinking water by eradicating invasive plants from the state’s protected forests. By allowing native plants to flourish, these forests could help combat climate change by sequestering carbon and allowing freshwater quivers to recharge with rainfall. Since 2013, the state has built 132 miles of fence to keep grazers away from forests to prevent the spread of seeds of invasive plants. However, this method can be expensive; a 1,400-acre fence cost over a million dollars.

Researchers successfully genetically engineered American Chestnut trees to resist the blight that decimated the species. Using a resistance-conferring gene from the wheat plant, the trees are grown in the lab and then can mate with trees in the wild to produce hardier blight-resistant trees. Although there are several regulatory hurdles to clear, and some environmental activists oppose the use of genetic modifications, the group continues to receive substantial grants and the trees have passed years of safety and efficacy tests showing they are safe and can even contribute to a healthy diet for many species.

Revegetation and fire management practices are helping to preserve Australia’s biodiversity. In Western Australia, collaborative efforts between Environs Kimberley, an environmental NGO, and local rangers from the First Nation communities of the Dampier Peninsula are working to document, conserve, and manage the region’s monsoon vine thickets (MVT). As part of the Kimberley Nature Project (KNP), local rangers employ traditional methods like seasonal burns to allow for revegetation and to reduce the threat of larger bushfires.
