Pritchardia remota, the Nihoa pritchardia, Nihoa fan palm, or Loulu, is a species of palm endemic on the island of Nihoa, Hawaiʻi, and later transplanted to the island of Laysan. It is a smaller tree than most other species of Pritchardia, typically reaching only 4–5 metres (13–16 ft) tall and with a trunk diameter of 15 centimetres (5.9 in). It is the only type of tree on the island and used to be abundant. In 1885 a wildfire ravaged the island, destroying most of the palms. Only about 700 of these trees remain, making the species endangered but numbers are slowly increasing. The palm is being cultivated in botanical gardens.
Pritchardia limahuliensis, the Limahuli Valley pritchardia, is a palm native to Hawaii. It is a rare species, only discovered in 1977 by staff of the National Tropical Botanical Garden in the Limahuli Garden and Preserve, Kauai, Hawaii, where it is now being conserved. It is threatened by introduced rats, which eat the seeds.

Amaranthus brownii was an annual herb in the family Amaranthaceae. The plant was found only on the small island of Nihoa in the Northwestern Hawaiian Islands, growing on rocky outcrops at altitudes of 120–215 m (394–705 ft).

The Palmetum of Santa Cruz de Tenerife is a botanical garden of 120.000 m² specialized in palms (Arecaceae). It is an artificial hill, with views of the ocean, located in Santa Cruz de Tenerife, Canary Islands, Spain. The gardens include a large system of waterfalls, streams and ponds, a museum dedicated to palms, and a display shade house. The project was started in 1995 on a former landfill and only opened to the public in 2014. The valuable palm collection gathers about 600 species of palms and it is focused on the ones native to world islands. Trees and shrubs of other plant families are also displayed, organised in "biogeographical sections". All gardens are maintained with no pesticides and no fertilizers, different species of wild birds are easily seen in the palmetum.
Otto Degener was a botanist and conservationist who specialized in identifying plants of the Hawaiian Islands.

Rene Sylva was a native Hawaiian botanist from Paia, Hawaii. He was among the only native Hawaiian fishermen to speak in favor of a ban on fishing green sea turtles. After giving up a career in turtle fishing, he became involved in the conservation of native Hawaiian ecosystems. He assisted renowned botanists Otto Degener and Dr. Harold St. John in surveying remote regions of the Hawaiian Islands for native plants.

The Hawaiian tropical dry forests are a tropical dry broadleaf forest ecoregion in the Hawaiian Islands. They cover an area of 6,600 km2 (2,500 sq mi) on the leeward side of the main islands and the summits of Niʻihau and Kahoʻolawe. These forests are either seasonal or sclerophyllous. Annual rainfall is less than 127 cm (50 in) and may be as low as 25 cm (9.8 in); the rainy season lasts from November to March. Dominant tree species include koa, koaiʻa, ʻakoko, ʻōhiʻa lehua, lonomea, māmane, loulu, lama, olopua, wiliwili, and ʻiliahi. Endemic plant species in the dry forests include hau heleʻula, uhiuhi, and Gouania spp. The palila, a Hawaiian honeycreeper, is restricted to this type of habitat.
