The Lepidium arbuscula is a very rare flowering plant. It belongs to the mustard family. This plant is also known by its common names, `anaunau and Waianae Range pepperwort.
The `anaunau` plant is endemic to Hawaii. This means it grows naturally only in Hawaii and nowhere else in the world. Specifically, you can find it in the Waianae Mountains on the island of Oahu. In 2003, there were fewer than 1,000 `anaunau` plants left in total. Because it is so rare, it is listed as a federally endangered species in the United States.
What Does the `Anaunau` Look Like?
The `anaunau` is a type of shrub. It can grow up to about 1.2 meters (almost 4 feet) tall. Its branches are often twisted and gnarled.
The leaves of the `anaunau` plant grow in groups. You will find these leaf clusters mostly at the ends of its branches. Scientists are still learning a lot about how this special plant lives and grows.
Why Is the `Anaunau` Endangered?
The `anaunau` plant faces many dangers that threaten its survival. Its main problem is the loss of its natural home, also called its habitat. This habitat is getting damaged or disappearing.
One big reason for this damage is the presence of feral animals. These are animals that used to be tame but now live in the wild. For example, wild goats and pigs roam where the `anaunau` grows. These animals eat the plants and destroy their habitat.
Another threat comes from introduced plant species. These are plants that were brought to Hawaii from other places. A plant called fire tree (Morella faya) is one example. These introduced plants can grow very fast and take over the space where `anaunau` needs to live. They compete for sunlight, water, and nutrients, making it hard for the native `anaunau` to survive.
