Why balance is critical to Hawaiʻiʻs ecology.
In the middle of the vast Pacific, Hawai’i’s extreme isolation makes it the world capital of endemism — meaning, for its size, Hawai’i has the highest rate of species that exist nowhere else on Earth.
Ecology
Because the Hawaiian archipelago is so remote, any plants or animals that arrived prior to humans, carried by wind or water, were only successfully established at the rate of one new species every 25,000 to 50,000 years. Hawaiian species evolved and co-evolved over millennia and are now as incredibly unique as they are extraordinarily vulnerable. By contrast, human-accelerated new alien species colonization now occurs at the rate of once every 18 days. Hand-in-hand with high rates of endemism, Hawaiʻi is now home to more endangered species per square mile than anywhere else on the planet.
The most pervasive threats to Hawaiian species are non-native and invasive plants and animals.
Lacking any large native herbivorous mammals, Hawaiian plants are not adapted to ungulate browsing and trampling. Invasive feral deer, pigs, goats, sheep, and cattle are responsible for widespread destruction of lowland ecosystems and continue to degrade remaining native ecosystems, including critical forested watershed that are vital to Hawaiʻiʻs water and soil resources.
