Karthala MODIS 20051125
Mount Karthala or Karthola ( ar, القرطالة ''Al Qirṭālah'') is an active volcano and the highest point of the Comoros at above sea level. It is the southernmost and larger of the two shield volcanoes forming Grande Comore island, the largest island in the nation of Comoros. The Karthala volcano is very active, having erupted more than 20 times since the 19th century. Frequent eruptions have shaped the volcano's 3 km by 4 km summit caldera, but the island has largely escaped broad destruction. Eruptions on April 17, 2005 and May 29, 2006 ended a period of quiet. Volcanic activity April 2005 eruption The eruption, which carried a risk of lava flows and deadly volcanic gas, caused the evacuation of 30,000 residents. The crater was clearly changed by the eruption. A grey field of ash surrounds the crater and the caldera itself seems larger and deeper. The crater lake, which formed after Karthala's last eruption in 1991 and once dominated the caldera, is now ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultra Prominent Peak
An ultra-prominent peak, or Ultra for short, is a mountain summit with a topographic prominence of or more; it is also called a P1500. The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. There are approximately 1,524 such peaks on Earth. Some well-known peaks, such as the Matterhorn and Eiger, are not Ultras because they are connected to higher mountains by high cols and therefore do not achieve enough topographic prominence. The term "Ultra" originated with earth scientist Steve Fry, from his studies of the prominence of peaks in Washington (state), Washington in the 1980s. His original term was "ultra major mountain", referring to peaks with at least of prominence. Distribution Currently, 1,518 Ultras have been identified above sea level: 639 in Asia, 356 in North America, 209 in South America, 120 in Europe (including 12 in the Caucasus), 84 in Africa, 69 in Oceania, and 41 in ...

Heathland
A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate. Heaths are widespread worldwide but are fast disappearing and considered a rare habitat in Europe. They form extensive and highly diverse communities across Australia in humid and sub-humid areas where fire regimes with recurring burning are required for the maintenance of the heathlands.Specht, R.L. 'Heathlands' in 'Australian Vegetation' R.H. Groves ed. Cambridge University Press 1988 Even more diverse though less widespread heath communities occur in Southern Africa. Extensive heath communities can also be found in the Texas chaparral, New Caledonia, central Chile, and along the shores of the Mediterranean Sea. In addition to these extensive heath areas, the vegetation type is also found in scattered locations acro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Comoros Olive Pigeon
The Comoros olive pigeon (''Columba pollenii''), also known as the Comoro olive pigeon, is a species of bird in the family Columbidae. It is found in Comoros and Mayotte. It is becoming rare due to habitat loss. Description Easily distinguishable from other pigeon species, the Comoros olive pigeon is the largest bird in the Comoro Islands. It has a dark plumage. Adolescent pigeons have a bright yellow bill, whereas older ones have a dull green or brown bill. The Comoros olive pigeon makes a very deep coo of "guk-ohoooo hoo hooo". Habitat Its natural habitat is subtropical or tropical moist montane forests and it can be found in Comoros (especially Mount Karthala) and Mayotte, with a higher-density population being observed in the latter. Status Although described as locally common in parts of Grand Comoro, the Comoros olive pigeon is in general a fairly scarce bird with a small total population. The chief threat it faces is the clearance of the forest habitat in which it lives ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking.

Karthala White-eye
The Karthala white-eye (''Zosterops mouroniensis''), also known as the Mount Karthala white-eye, Grand Comore white-eye, or Comoro white-eye, is a species of bird in the family Zosteropidae. As suggested by its name, it is endemic to '' Philippia'' heath woodland growing on Mount Karthala on the island of Grand Comore in the Comoros. Mount Karthala is an active volcano and future eruptions pose a serious threat to the Karthala white-eye. The bird is further threatened by human-induced habitat loss. The bird is approximately 13 cm long with olive upperparts and yellow-green underparts. It has a white ring around the eye. Its diet consists of fruits and insect Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum.

Humblot's Flycatcher
Humblot's flycatcher (''Humblotia flavirostris'') or the Grand Comoro flycatcher, is a small passerine bird belonging to the Old World flycatcher family. It is the only member of its genus.
