What Kinds of Plants Live on Nihoa?
The plants on Nihoa can be put into different groups based on how they got there and where else they grow. It's like having different types of friends in your neighborhood!
Endemic Plants: Nihoa's Superstars
Endemic plants are the rarest kind. They are found only on Nihoa Island and nowhere else in the entire world! Imagine having a plant that grows only in your backyard and nowhere else – that's how special these plants are. They need extra protection because if they disappear from Nihoa, they're gone forever.
- The Loulu palm (Pritchardia remota) is a great example. It's a type of palm tree that grows only on Nihoa. It's a living reminder of how unique this island is.
- Another superstar is the Nihoa carnation (Schiedea verticillata). It's a beautiful plant that also calls only Nihoa home.
- Amaranthus brownii is another plant that is endemic to Nihoa.
Indigenous Plants: Natural Travelers
Indigenous plants are those that arrived on Nihoa all by themselves, without any help from people. They might have traveled by wind, on the feet of birds, or floated across the ocean. These plants also grow naturally in other places, but they found their way to Nihoa long ago and made it their home.
- The ʻIlima (Sida fallax) is a beautiful plant with small, yellow-orange flowers. It's indigenous to Hawaii and is often used to make leis.
- The Beach morning glory (Ipomoea pes-caprae) is another indigenous plant. You might see its pretty purple flowers growing along beaches in many parts of the world, including Nihoa.
- Other indigenous plants on Nihoa include the ʻAkoko (Euphorbia celastroides), the ʻOhai (Sesbania tomentosa), and the Popolo (Solanum americanum).
Naturalized Alien Plants: New Neighbors
Naturalized alien plants are those that were brought to Nihoa by people, either on purpose or by accident. Once they arrived, they managed to grow and spread on their own, becoming part of the island's plant life. Sometimes these plants can cause problems for the native plants, so scientists keep a close eye on them.
- The Sword fern (Nephrolepis multiflora) is an example of a naturalized alien plant found on Nihoa. It's a common fern that can grow in many places.
- The Sandbur (Cenchrus echinatus) is another one. You might know it for its spiky seeds that can stick to your clothes or shoes!
- New Zealand spinach (Tetragonia tetragonoides) and Common purslane (Portulaca oleracea) are also examples of plants that were introduced to Nihoa and now grow there naturally.
Protecting Nihoa's Plant Life
Because Nihoa has so many special and rare plants, it's very important to protect the island. Scientists and conservationists work hard to make sure these plants can continue to grow and thrive. They monitor the plants, study how they live, and try to prevent new alien species from arriving and harming the unique ecosystem. By understanding the different types of plants and their stories, we can appreciate just how amazing and important Nihoa Island is!
