Coihues

Coihues are a group of evergreen trees belonging to the genus Nothofagus. They are native to the southern regions of South America, particularly in Chile and Argentina, where they are a prominent feature of the temperate rainforests. The most common species is Nothofagus dombeyi, widely known simply as coihue. Other species, such as Nothofagus betuloides (southern coihue) and Nothofagus pumilio (lenga), are also often referred to as coihues in their respective ranges.

These trees are characterized by their smooth, gray bark and their distinct foliage. The leaves are typically small, ovate, and serrated, often turning shades of red, yellow, or orange in autumn before falling in some species, while others remain evergreen. Coihues are hardy and can tolerate a range of conditions, often thriving in areas with high rainfall and cooler temperatures. They play a vital role in their ecosystems, providing habitat and food for various wildlife.

Historically, coihue wood has been used for construction, furniture making, and as firewood due to its durability and density. The trees are also culturally significant in indigenous communities of Patagonia. In recent times, there has been growing awareness about the importance of conserving these forests, which face threats from deforestation, fires, and climate change. Conservation efforts are underway to protect coihue populations and their unique forest environments.
