The discovery of the Sitka Alder on this blustery day in Homer, a place most Alaskans know for its rugged coastal beauty and abundant wildlife, gave me insight into the tenacity of native plant species in the face of challenging environmental conditions. Its multifaceted role in promoting biodiversity, stabilizing coastal ecosystems, and offering sustenance to wildlife (Sitka alder) underscores its ecological significance in our region.
The Sitka Alder, an integral part of Alaska's native flora, is a deciduous shrub belonging to the Alnus genus in the Betulaceae family. Typically ranging in height from 3 to 12 feet (1 to 4 meters), this shrub is instantly recognizable by its serrated leaves, small cones, and its ability to fix nitrogen in the soil through a symbiotic relationship with nitrogen-fixing bacteria (Frankia Alni.). These traits contribute to its remarkable resilience and adaptability.
Traditionally, Native Alaskans used the Sitka Alder for a number of things from availing themselves fo the tannins found in the bark as a tanning agent, to building sheters , band basketry, as a medicine to treat inflammation, and even a dye to produce shades of red and brown (Turner, Nancy).
As we continue to explore and appreciate the natural wonders around us, it is essential to recognize and protect species like the Sitka Alder. Their contribution to the resilience and beauty of our natural landscapes is a reminder of the intricate web of life that thrives even in the harshest of environments and I’m afraid with all the development around us, we are interfering with that perfect natural balance.
