Alnus jorullensis, commonly known as Mexican alder or evergreen alder, is a fast-growing tree species in the Betulaceae family. Native to Mexico and Central America, it can reach heights of up to 30 meters. The tree features a straight trunk with smooth gray bark and dark green, glossy leaves that are hairy on the underside. These oval-shaped leaves have serrated edges and can measure up to 15 cm in length.
Mexican alder plays a vital role in reforestation projects due to its ability to fix nitrogen in the soil through its roots. This characteristic makes it an ideal plant for soil conservation efforts, as it enhances soil fertility and helps prevent erosion.
In early spring, before new leaves emerge, the tree produces small flowers that are followed by small, cone-like fruits. These fruits contain seeds that can be dispersed by wind or water.
The uses of Mexican alder are numerous. It serves as a shade tree for coffee plantations, provides timber for furniture making and construction due to its strong wood, and is also valued as an ornamental plant in gardens and parks because of its attractive foliage.
Overall, Alnus jorullensis is a versatile species with many benefits, making it an important part of ecosystems across Mexico and Central America.
