The islands have become highly noted for their flora and fauna, attracting ecotourists. One endemic, the Chatham Islands forget-me-not (Myosotidium hortensia), has become a botanical symbol of the islands due to its widespread cultivation in and outside New Zealand. [3] [2] The Chatham archipelago comprises 40 islands and rocks.
Hematite (/ ˈ h iː m ə ˌ t aɪ t, ˈ h ɛ m ə-/), also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. [6] Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3. It has the same crystal structure as corundum ...
This category contains flora that are native to the Pitcairn Islands in the south-central Pacific Ocean. Taxa of the lowest rank are always included. Higher taxa are included only if endemic. The categorisation scheme follows the World Geographical Scheme for Recording Plant Distributions.
[2] [3] In a report to Parks Australia in 2002, of the many introduced species on the southern atoll, Chromolaena odorata (Siam weed) was identified as being the greatest threat to the environment. [3] Most of the introduced species are pantropical herbaceous plants likely introduced to the southern atoll after the airfield was built in 1944. [2]
The flora of the Chatham Islands consists of around 388 terrestrial plant species, of which 47 are endemic. [1] The Chatham Islands make up the Chatham floristic province of the Neozeylandic Region of the Antarctic Kingdom. The flora of the Chatham Islands include: Phormium chathams (Chatham Island flax)
The endemic plants of Saint Helena include many notable Cabbage Tree or, "insular arborescent Asteraceae", members of the daisy family which have evolved a shrubby or tree-like habit on islands. Other notable endemics include the closely related St Helena redwood ( Trochetiopsis erythroxylon ) and St Helena dwarf ebony ( Trochetiopsis ebenus ).
There are no native forests in the Faroe Islands, and only a few woody plants occur. Findings of Betula pubescens trunks and branches in the soil, dated to c. 2300 BC, and the abundance of Corylus pollen in deep layers, suggest that at least some local stands of birch and hazel trees were present in the Faroe Islands, prior to human settlement.
The islands' trees were cut for their timber, and Persea indica was the most sought-after. In the 16th and 17th centuries the southern side of Madeira was converted to sugarcane plantations. A system of levadas, water channels 80 to 150 centimetres (31 to 59 in) wide, was constructed of stone and later concrete to irrigate the sugarcane fields ...
