Mapumai Swamp
Mapumai Swamp is the largest wetland in the Cook Islands. It is located in the north of Atiu, on the edge of the volcanic area. Its flora is dominated by ''Cladium'', giant bullrush, and ''Azolla filiculoides ''Azolla filiculoides'' (water fern) is a species of ''Azolla'', native to warm temperate and tropical regions of the Americas which was introduced to Europe, North and sub-Saharan Africa, China, Japan, New Zealand, Australia, the Caribbean and H ...''.

Atiu
Atiu, also known as Enuamanu (meaning ''land of the birds''), is an island of the Cook Islands archipelago, lying in the central-southern Pacific Ocean. Part of the Nga-pu-Toru, it is northeast of Rarotonga. The island's population has dropped by two-thirds in the last 50 years. Geography Atiu is a raised volcanic island surrounded by a reef from which rise cliffs of fossilized coral (''makatea''). The makatea cliff forms a ring round the island, creating a virtual plateau. Erosion of the inside of the ring has formed a dip of about into fertile land, which gradually rises again to a central flat-topped hill. The low swampy land consists of taro plantations, marshes and a lake, Tiroto. This fertile area also grows bananas, citrus fruits, pawpaws, breadfruit and coconuts. The island is surrounded by a fringing reef. The ''makatea'' is honeycombed with caves, some of which have been used for burials. History Polynesians are believed to have lived on Atiu since at least ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cladium
''Cladium'' (fen-sedge, sawgrass or twig-sedge) is a genus of large sedges, with a nearly worldwide distribution in tropical and temperate regions. These are plants characterized by long, narrow (grass-like) leaves having sharp, often serrated (sawtooth-like) margins, and flowering stems 1–3 m tall bearing a much-branched inflorescence. Like many plants found in wet habitats, it has deeply buried rhizomes that can produce tall shoots with dense canopies. ''Cladium mariscus ''subsp.'' jamaicense'', or saw-grass, is common in marshes and savannas throughout the tropical Americas. One typical and well-known area of extensive saw-grass growth is the Florida Everglades; sawgrass is the plant referred to by the descriptor, "River of Grass". Like many species of the Everglades, ''C. jamaicense'' grows in extremely infertile conditions, particularly wet sites that are low in phosphorus. Dense sawgrass beds are intermingled with other vegetation types. Together they produce a rich arr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schoenoplectus Californicus
''Schoeneoplectus californicus'' is a species of sedge known by the common names California bulrush, southern bulrush and giant bulrush. It is also sometimes called "tule", but the closely related ''Schoenoplectus acutus'' is the species most often referred to by that name. Description ''Schoenoplectus californicus'' is a rhizomed water plant found in marshy areas. It is native to the southern and western United States as well as Mexico, Central America, South America, Easter Island, and the Falkland Islands. It is naturalized on some Pacific islands including New Zealand, Hawaii and the Cook Islands. It has tall, thin, dark green stems which are usually triangular in cross-section and woolly, bristly tan or brown flowers in panicle inflorescences. Uses A notable subspecies is the totora, ''Schoenoplectus californicus'' subsp. ''tatora''. This is famous for making up the floating islands on which the Uros people of Lake Titicaca dwell, as well as occurring on isolated Eas ...

Azolla Filiculoides
''Azolla filiculoides'' (water fern) is a species of ''Azolla'', native to warm temperate and tropical regions of the Americas which was introduced to Europe, North and sub-Saharan Africa, China, Japan, New Zealand, Australia, the Caribbean and Hawaii. It is a floating aquatic fern, with very fast growth, capable of spreading over lake surfaces to give complete coverage of the water in only a few months. Each individual plant is 1–2 cm across, green tinged pink, orange or red at the edges, branching freely, and breaking into smaller sections as it grows. It is not tolerant of cold temperatures and, in temperate regions it largely dies back in winter, surviving by means of submerged buds. It harbors the diazotrophic organism, ''Nostoc azollae'', in specialized leaf pockets. This ancient symbiosis allows ''N. azollae'' to fix nitrogen from the air and contribute to the fern's metabolism. Fossil records from as recent as the last interglacials are known from several location ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of The Cook Islands
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
