California’s Urban Forests Have Lowest Tree Cover per Resident

By Neha Jain @lifesciexplore California’s urban forests are not just a pretty sight; they are an asset valued at a whopping $181 billion, finds a new study. But, according to the study, the state’s urban tree cover at 90.8 square meters (109 square yards) per city resident is the lowest among all US states. The good news is that there are 236 million spots available for more trees to be planted. The study finds that urban forests cover 15 percent of the urban area in California, consisting of 173 million…

Wire Netting on Trees Reduces Impact by Elephants

By Kelly Derham African elephants (Loxodonta africana) are massive, weighing up to 7 tons, and eat up to 300 pounds of food in one day. Much of their diet is made up of various parts of trees, including the bark, leaves, branches, roots, and thorns. When elephants feed on trees, they are capable of knocking the trees over, which can create habitats that are more suitable for other animals, such as antelopes, lizards, or ants, than for the elephants themselves. Because elephants create altered environments through their feeding habits they…

Saving Forests with Artificial Intelligence

By Norman Rusin The global trade in products made from illegally extracted timber is a multi-billion dollar industry. The World Wildlife Fund (WWF) estimates it to be worth between $30 billion and $100 billion annually. The practice not only threatens ancient forests and critical habitats for wildlife, but also results in significant economic and environmental problems for many developing countries. Clear-cutting is known to disrupt carbon in the soil. However, forest protection agencies face limited budgets and must cover large areas, making sound investments in security resources critical. AI to…

Arborsculpture: Artful Science of Tree Shaping

By Ansel Oommen Our Earth is hungry for solutions. From climate change and deforestation to overpopulation and pollution, our lives are ever dependent on our delicate dealings with the environment. But amongst the grassroots we are seeing a resurgence of an ancient practice of combining art and science, humanity and nature, to deliver an innovative contemporary response: Arborsculpture. A Brief History of Tree Shaping Dating as far back as the sixteenth century, tree shaping has been hinted at in paintings and literature, but it was not until Axel Erlandson, the…
