Rewilding Projects Around the World

Have you ever been out walking through an empty street and come across a small patch of wildflowers? If so, you have already experienced a glimpse of what rewilding is. It is the concept that if nature is given space to grow and thrive, then it will flourish on its own. On a small scale, it can look like small flowers growing in the cracks of old pavement. However, larger rewilding projects around the world demonstrate how powerful this restoration can be.

Rewilding is a form of ecological conservation that helps damaged ecosystems return to their natural state. This is achieved in three key ways: habitat restoration, reintroduction of native species, and minimizing human intervention. This provides ecosystems the space and conditions they need so they can thrive. Restoring habitats focuses on repairing changed environments, such as replanting forests, removing man-made dams, and restoring wetlands. By giving nature a helping hand, the environment is able to return to its natural processes. This can also be accomplished through returning native species that have been reduced or extinct from an area as a result of human activity. The point of this is to restore the balance of an ecosystem and the biodiversity that was lost. This typically includes bringing back a keystone species: a particular species that has a disproportionately large effect on its ecosystem. This means that it plays a vital role in keeping the structure and balance of its ecosystem. Whether rewilding projects focus on fixing habitats or biodiversity, it is most important to minimize human impact on the environment so that it can heal itself.

One of the most famous rewilding efforts is the reintroduction of wolves in Yellowstone National Park. In 1995, wolves were reintroduced to Yellowstone after being over hunted to extinction 70 years prior. Their absence had a large impact on the biodiversity of Yellowstone, including a surge in deer populations, which led to a decrease in vegetation. When the wolves came back, the plants flourished, and deer populations were more controlled as expected. What nobody predicted is how many other benefits the wolves brought. Due to the increase in vegetation, beavers returned, building dams that made habitats for birds and fish. Even the landscapes were affected since the trees stabilized the river banks and erosion decreased. This is a famous example of rewilding because of the immense impact the wolves had on transforming the entire ecosystem.

Rewilding isn’t limited to forests and plains, but many efforts are being made in marine ecosystems as well. These underwater habitats have been harmed by pollution and overfishing, which have had detrimental effects on the species that live there. One of the biggest examples of marine rewilding is through the conservation of oyster reefs in the New York Harbor. Projects like the Billion Oyster Project have helped to restore the abundance of oysters in waterways surrounding the city. Oyster reefs are very valuable because they filter the water, provide a habitat for many marine creatures, and prevent erosion on shorelines. By reinstating oyster populations in New York, the entire waterway was revitalized with clearer water and a greater biodiversity.

These efforts illustrate nature’s ability to heal and prosper when given the room to. From parks to oceans, rewilding gives the opportunity to restore the balance of these ecosystems.
