Nature Walk – Zone 5
Hawaii’s native flora is as unique as it is diverse, with approximately 1,400 vascular plant taxa native to the islands, and nearly 90% of these are found nowhere else in the world. The rich tapestry of plants includes the native Akia plant, the Pohinahina, used medicinally by native Hawaiians, and the Kupukupu fern used in traditional Hula, are just a few examples of the islands’ botanical treasures. Conservation efforts are crucial to protect these species from threats such as habitat loss, invasive species, and climate change. Initiatives include surveying historic ranges, augmenting wild populations, and establishing new ones in safe harbors. The MTA Nature Walk was developed to highlight these plant species and other important fauna of Hawaiian culture and landscapes.
