Detailed explanation-1: -Explanation: This is one of the consequences of the importation of animal and plants in Hawaii. When an organism (animal or plant) is imported into a region, it often leads to the decline of native species. This is due to several factors, including the spread of diseases, competition for land and lack of predators.

Detailed explanation-2: -The current, most pervasive threats to Hawaiian biodiversity in Hawaii are non-native invasive, habitat-modifying plants, animal and disease. For many endangered species, small populations make recovery difficult.

Detailed explanation-3: -Human arrival Both the Polynesians and Europeans cleared native forests and introduced non-indigenous species for agriculture (or by accident), driving many endemic species to extinction.

Detailed explanation-4: -Many of the plants and animals on the islands are so similar to species elsewhere that they obviously were brought to Hawaii by the humans who began colonizing the islands between approximately 1, 200 and 1, 600 years ago.

Detailed explanation-5: -Ungulates: Invasive Creatures Great and Small Ungulates or hoofed animals such as pigs, sheep, deer, and goats pose a significant threat to native plants in Hawaii. These hoofed animals can graze or uproot hundreds of plants in just one night and contribute to soil degradation and erosion.
