The Andaman Islands is an archipelago in the northeastern Indian Ocean about 130 km (81 mi) southwest off the coasts of Myanmar's Ayeyarwady Region. Together with the Nicobar Islands to their south, the Andamans serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east. Most of the islands are part of the Andaman and Nicobar Islands, a Union Territory of India, while the Coco Islands and Preparis Island in the archipelago's north belong to Myanmar.

Living collections of this taxon from the Andaman Islands is under ex situ conservation outside the islands at the Field Gene Bank of Jawaharlal Nehru Tropical Botanic Garden and Research Institute, Trivandrum, India. It is a pre-tsunami accession.

Mount Harriet, which is part of the park, is the third-highest peak in the Andaman and Nicobar archipelago next to Saddle Peak in North Andaman and Mount Thullier in Great Nicobar.

Phoenix andamanensis is a wild relative of date palm endemic to the Andaman Islands in the Bay of Bengal southwest of Myanmar. It is rather a newly described taxon by Sasha C. Barrow in 1998 based on old herbarium collections. This taxon was known only from a few herbarium collections and a few insignificant citations by Kurz in 1870, Brandis in 1906 and Parkinson in 1923. The Herbarium collections were made mostly during the British regime in 1903, 1904 and 1911 by Rogers and Osmaton. Later, Ellis from the Botanical Survey of India in 1990 collected one specimen from the Saddle Peak. The specimens were remained unidentified at herbaria until its circumscription as new taxon by Barrow in 1998.
The Andaman shrew or Andaman white-toothed shrew is a critically endangered species of mammal in the family Soricidae. It is endemic to the South Andaman Island of India. They are usually active by twilight or in the night and have specialized habitat requirements. Habitat loss due to selective logging, natural disasters such as tsunami and drastic weather change are thought to contribute to current population declines.
Korthalsia rogersii is an endangered endemic rattan species, thought to be extinct from the insular habitat of the Andaman Islands in the Indian Ocean until 1993. Korthalsia rogersii was first described by Odoardo Beccari in 1918 based on two herbarium field specimens collected by C. G. Rogers in 1904 from the South Andaman Island. This species was known only from these two collections until 1993. Sam Mathew and Pakshirajan Lakshminarasinhan were able to find the species again at Chidiyatapu forests of the South Andamans after a gap of about 100 years. Live collections are introduced at Tropical Botanical Garden and Research Institute, Trivandrum, South India.
Pteroceras muriculatum is an endemic endangered orchid reported from the Andaman Islands in the Bay of Bengal. This insular orchid was first described by Reichenbach in 1881 as Thrixspermum muriculatum Rchb. f. based on a few specimens procured during the latter part of 19th century by Mr W. Bull. This taxon has not been reported until 2005 after the type collection. During the floristic survey of South Andaman Islands carried out by Sam Mathew for the 'Flora India Project' of the Botanical Survey of India, this taxon was relocated in 1993 from the semievergreen forests at Chidiyatappu region. Pteroceras muriculatum P. F. Hunt is a beautiful small epiphytic orchid having creamy white flowers with distinct transverse purple bands on petals. A living specimen collected from South Andaman Island is conserving at the Field Gene Bank of Jawaharlal Nehru Tropical Botanic Garden and Research Institute, Trivandrum, India.
Vanilla andamanica is an endangered wild relative of commercial vanilla, Vanilla planifolia, the source of Vanilla essence. It grows in the Andaman and Nicobar Islands, India in the Bay of Bengal., and classified as a Vulnerable species (VU) by the IUCN Red List.

Its berries are sometimes pressed for an oil that is also used in cooking.
Rotala andamanensis is a lesser-known endemic wetland plant species of the Andaman Islands in the Bay of Bengal belonging to the family Lythraceae. The type locality of this species is Wright Myo, the southern slope of the Mount Harriet Hill ranges. This is a rather rare species found to occur along the wetland area of the region. The specimens were originally collected by Balakrishnan of the Botanical Survey of India and described by Sam Mathew and Lakshminarashimhan of the same institution in 1992.
A large, very high liana, or climbing tree in the Arecaceae palm family, Korthalsia laciniosa occurs in the closed forests of Java, Sumatra, the Philippines, Malay Peninsula, Vietnam, Cambodia and elsewhere in Indochina, and the Nicobar and Andaman Islands. The palm usually grows in lowland forests, often close to the coast, however on the Malay peninsula it has been observed growing in hill Dipeterocarp forests up to 1000m elevation. It occurs in clumps of 4 to 20 individual stems, up to 7.2m high, in the tropical and subtropical monsoon rain evergreen forests of Bạch Mã National Park in Thừa Thiên-Huế Province, central Vietnam. It is described as a common species in the Andaman Islands, growing in the moist semi-evergreen and deciduous forests belt. Senthilkumar et al. however found it abundant in South Andaman, less common in Middle and North Andaman, and not common in the Nicobar Islands.
