It used to be that the Hawaiian ecosystems with the highest diversity of plant species were moist and wet forests.  Today, the highest plant diversity can be found in our yards and botanical gardens, and the number of plant species introduced to Hawaii grows each year.  Although the vast majority of Earth’s 250,000+ plant species would not be invasive if imported and grown in our islands, a small percentage would be superweeds that alter the ecosystem or natural resources.  Plants are not checked for their potential to become invasive when they are imported, and our noxious seed and weed rules regulate less than 100 species of plants, most of which are already present in Hawai‘i.
