What Kind of Plants & Animals are in Haleakala National Park?

Topics: , , ,
With its moon-like surface and high elevation, Haleakalā National Park is one of the region’s most unique habitats. At first glance, it’s hard to believe that plants would grow on its barren terrain, but Haleakalā National Park is home to some of the island’s most beautiful, and rare, plants. On our Haleakalā National Park Sunrise Tour, Haleakalā National Park Sunrise & Zip Tour, or the HaleakalÄ National Park Sunrise Bike & Zip Tour, we urge tour goers to keep their eyes out for the hidden gems listed below:  Haleakalā Silversword. Perhaps one of the most iconic plants on the island, the Haleakalā Silversword boasts thick, stiff leaves with pink, purple, or white flowers. It’s hard to miss—the Haleakalā Silversword can grow up to nine feet in height. Although an endangered species, the sturdy and colorful plant can be found between 7,000 and 10,000 feet of elevation. The peak season for the Haleakalā Silversword is from mid-June to November. No need to worry, though, if you’ve missed this season—the Haleakalā Silversword can live for up to 70 years. You can get a glimpse of the plant’s silver hairs and vibrant flowers on any of our Haleakalā National Park tours.

The Geranium cuneatum, also known as the “silver geranium,” is one of the most common species located in the Haleakalā area. You’ll recognize this flower by its small silvery leaves, covered with short, silky hairs. Think sun protection is reserved for those on the beach? Think again. The small, soft hairs on the Geranium cuneatum are there to reflect the Hawaiian sunshine in order to help preserve moisture.

The Geranium multiflorum, also referred to as the “many flowered geranium”, can be spotted by its small pink, purple, and white flowers. The flower’s leaves are often tinted with a red hue, which is an environmental adaptation that protects the plant from the heat of the alpine sun. The Geranium multiflorum thrives in the Haleakalā National Park area, as they’re most commonly found in high-altitude grasslands and forests.

Haleakalā National Park is mostly known for being home to Hawaii's largest dormant volcano, but it’s also home to another Hawaiian rarity. The Geranium arboreum, with its magenta petals, is the only bird-pollinated geranium in the world. Unfortunately, this flower is critically endangered. Despite conservation efforts, the Geranium arboreum is now restricted to nine isolated populations with fewer than 50 individuals. Keep your eyes peeled for this small but mighty beauty, easily identified by the curve of its purple flowers. It can be found on the lower slopes of Haleakalā National Park.

Hawaiian Sandalwood - ‘lli’ahi Hawaiian Sandalwood, also known as ‘lli’ahi, once covered the slopes of Haleakalā. This Sandalwood plant was loved by many for its sweet scented wood, and quickly became a hot commodity across the island. Its high-demand almost eliminated the plant off of the island, but thanks to new developments in horticultural techniques, hundreds of Koa and Sandalwood trees have sprouted across the region. In an additional effort to save this rare species, there was a large replanting effort that has effectively reintroduced this species to the area and it can now be found once again in Haleakalā National Park. Keep your eyes (and nose) peeled for these beautiful and fragrant plants when exploring between 7,000 and 10,000 feet in elevation.

Nene Goose Duck... duck... goose? The Nene Goose, in fact. A smaller member of the goose family, the Nene Goose is the Hawaiian state bird. While the Nene Goose is a threatened species of bird, they’ve made a significant comeback after nearly going extinct a few decades ago. The Nene Goose are now commonly spotted across the islands. Be careful not to mistake the Nene for the well-known Canadian Goose, as it is believed that the Nene is a descendant of the Canadian Goose and their appearance is noticeably similar. Wondering where you can see the famous Nene Goose? If you’re not seeing them in the summit area of Haleakalā, where they’re most commonly found on the island of Maui, try looking up. The Nene survived into the 20th century because they retained the ability to fly - where as 6 other species of large geese or ducks (some up to 4 ½ feet tall!), once native to Hawai’i are now extinct because they lost their ability to fly over millions of years of evolution in Hawai’i before human arrival, and before any predators were here.

The Ua’u, also known as the Hawaiian Petrel, is another Hawaiian bird worth looking out for on your tour of Haleakalā National Park. An endangered species, the majority of these seabirds are found on Maui, specifically within Haleakalā National Park. This area appeals to them as the lava rocks provide comfortable nesting burrows in the springtime. In fact, Haleakalā is known to have the largest nesting colony of the ‘Ua’u anywhere in Hawai’i. Pay close attention when looking for these volcano dwellers, as they’re often hiding in their burrows between 8,000 to 10,000 feet of elevation or soaring across the ocean hunting for squid. October and November are the most popular times to see the ‘Ua’u, as this is when their new chicks are learning to fly on their own before heading out to sea for two months straight.
