Achada Plateau
The Achada Plateau (Portuguese: ) is an extensive volcanic mountain range located on Pico Island, Azores. It is a protected area with many valuable features that characterize the Azorean landscape. It is included in two Natura 2000 sites, one of which is classified as an Important Bird Area. Part of the plateau also includes a ramsar wetland. It is one of the three main geomorphological units that comprise Pico Island. Location and geomorphology The Achada Plateau is located on the highlands of Pico, the highest and second largest island on the archipelago of the Azores. The extensive volcanic mountain range, located in the eastern half of the island at a mean altitude of , stretches from Lagoa do Capitão (northeast of Mount Pico) to the easternmost part of the island. It is characterized by the steep slopes that limit it to the south and north and by the presence in the axial zone of the range of various volcano-tectonic alignments of cinder and spatter cones and eruptive fiss ...

Topo Volcano
Topo Volcano (Portuguese: ) is an inactive shield volcano located on Pico Island, Azores. The volcano measures in height and occupies the southernmost area of the island. It is part of the Lajes (or Topo) Volcanic Complex, the oldest volcanic apparatus which gave origin to the island, around 300,000 years ago. The volcano was created by a thick superposition of alternated Pāhoehoe lava flows and thin layers (10%) of pyroclastic material. Its land area is approximately but its total area, accounting for the sea floor and the area that gave rise to the Achada Plateau The Achada Plateau (Portuguese: ) is an extensive volcanic mountain range located on Pico Island, Azores.

Volcanic Crater Lake
A volcanic crater lake is a lake in a crater that was formed by explosive activity or a collapse during a volcanic eruption. Formation Lakes in calderas fill large craters formed by the collapse of a volcano during an eruption. Lakes in maars fill medium-sized craters where an eruption deposited debris around a vent. Crater lakes form as the created depression, within the crater rim, is filled by water. The water may come from precipitation, groundwater circulation (often hydrothermal fluids in the case of volcanic craters) or melted ice. Its level rises until an equilibrium is reached between the rates of incoming and outgoing water. Sources of water loss singly or together may include evaporation, subsurface seepage, and, in places, surface leakage or overflow when the lake level reaches the lowest point on its rim. At such a saddle location, the upper portion of the lake is contained only by its adjacent natural volcanic dam; continued leakage through or surface outflow ac ...

Lagoa Do Caiado
Lagoa do Caiado is the largest lake on Pico Island, Azores. The high-altitude lake is located on the Achada Plateau, an extensive volcanic mountain range covering most of the central area of the island. The waters are clear and are used for public supply since 1993. Sitting at around in altitude, in a cinder cone dominated landscape, the area around the lake is densely vegetated due to the extreme humidity it gets (around of precipitation each year). Unlike the rest of the Azores, which have been subject to introduction of exotic species, most of the plant-life around the lake is endemic to the archipelago (''Juniperus brevifolia'', ''Picconia azorica'', ''Erica azorica'', ''Vaccinium cylindraceum''). It is one of the best spots for birdwatching in the island, most commonly found are the Eurasian woodcock, the common snipe, the Eurasian teal, the grey heron, the wagtails and the Azores chaffinch The Azores chaffinch (''Fringilla coelebs moreletti'') is a small passerine bird ...

Ramsar Wetland
The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of Ramsar sites (wetlands). It is also known as the Convention on Wetlands. It is named after the city of Ramsar in Iran, where the convention was signed in 1971. Every three years, representatives of the contracting parties meet as the Conference of the Contracting Parties (COP), the policy-making organ of the convention which adopts decisions (resolutions and recommendations) to administer the work of the convention and improve the way in which the parties are able to implement its objectives. COP12 was held in Punta del Este, Uruguay, in 2015. COP13 was held in Dubai, United Arab Emirates, in October 2018. List of wetlands of international importance The list of wetlands of international importance included 2,331 Ramsar sites in May 2018 covering over . The countries with most sites are the United Kingdo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lakes
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ponds
A pond is an area filled with water, either natural or artificial, that is smaller than a lake. Defining them to be less than in area, less than deep, and with less than 30% emergent vegetation helps in distinguishing their ecology from that of lakes and wetlands.Clegg, J. (1986). Observer's Book of Pond Life. Frederick Warne, London Ponds can be created by a wide variety of natural processes (e.g. on floodplains as cutoff river channels, by glacial processes, by peatland formation, in coastal dune systems, by beavers), or they can simply be isolated depressions (such as a kettle hole, vernal pool, prairie pothole, or simply natural undulations in undrained land) filled by runoff, groundwater, or precipitation, or all three of these. They can be further divided into four zones: vegetation zone, open water, bottom mud and surface film. The size and depth of ponds often varies greatly with the time of year; many ponds are produced by spring flooding from rivers. Ponds may be f ...

Peat Bog
A bog or bogland is a wetland that accumulates peat as a deposit of dead plant materials often mosses, typically sphagnum moss. It is one of the four main types of wetlands. Other names for bogs include mire, mosses, quagmire, and muskeg; alkaline mires are called fens. A baygall is another type of bog found in the forest of the Gulf Coast states in the United States.Watson, Geraldine Ellis (2000) ''Big Thicket Plant Ecology: An Introduction'', Third Edition (Temple Big Thicket Series #5). University of North Texas Press. Denton, Texas. 152 pp. Texas Parks and Wildlife. Ecological Mapping systems of Texas: West Gulf Coastal Plain Seepage Swamp and Baygall'. Retrieved 7 July 2020 They are often covered in heath or heather shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink. Bogs occur where the water at the ground surface is acidic and low in nutrients. In contrast to fens, they derive most of t ...

Exotic Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neoph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
