  • Drive cautiously - Endangered birds land on roadway

    Nēnē (Hawaiian geese) are nesting in the park and may land on or frequent park roads and parking lots. Drivers are reminded to drive at the posted speed limits and exercise caution.

    The Summit and Kīpahulu Districts are remote. An ambulance can take up to 45 minutes to arrive at either district from the nearest town. People with respiratory or other medical conditions should also be aware that the summit of Haleakalā is at 10,000 ft.

Environmental Factors

Soil erosion caused by rooting pigs--non native to the park.
Soil erosion is colossal in a rainforest climate where non native pigs have ravaged the ground cover on steep slopes.

Rainforests on Haleakalā's steep windward slopes receive as much as 120 inches of annual rainfall. These forests are stable and enduring when not subject to depredation by pigs and goats. Ungulate's rooting and grazing quickly break down the native plant cover triggering devastating erosion. Such landscape scale erosion on tropical mountain slopes devastates both the native biodiversity and the island's precious groundwater reserve.

But Haleakalā upper elevations are now free of pigs and goats, and serves as a core area in the East Maui Watershed Partnership to protect this native rainshed and its groundwater from this destruction.

While native species once arrived every 30,000 years, today a new species hitchhikes to Hawaiʻi about once every 20 days. Many of these amazing travelers can be found in Haleakalā National Park.
