Goda Mountains
The Goda Mountains lie northwest of the Gulf of Tadjoura, Tadjoura Region in Djibouti. They rise to above sea level and are the nation's largest heavily vegetated area and is the second highest point in Djibouti. The name Goda in Afar means "twisted" or "devoured" and refers to a ridge. A part of the mountains is protected within the Day Forest National Park, Djibouti's only national park. The ecology of this landform is considered an isolated outlier of the Ethiopian montane forest ecological zone, an important island of forest in a sea of semi-desert. Ecology The Goda Mountains and the nearby Mabla Mountains are the last remaining refuge for the Djibouti spurfowl. It is also one of the few remaining habitats of the East African juniper, which was once the dominant tree species of the forest. The population of juniper trees in the area has sharply declined, with approximately 50% of the trees dying even in the healthiest regions. Instead, boxwood has become more common. Subseque ...

Tadjourah Region
The Tadjourah Region so, Gobolka Tajoora, aa, Rakaakay Tagórri) is a region in north-central Djibouti, the largest of its six regions. With its capital at Tadjourah, it has an area of 7,100 square kilometres (2,700 sq mi). It lies along the Gulf of Tadjoura, and the coastal city of Tadjoura. The region has active salt and fisheries industries, and is served by the Tadjoura Airport. In total area, it is larger than Brunei and smaller than Cyprus. History The boundaries of the present-day Djibouti nation state were established during the Scramble for Africa. The first French establishment in the Horn of Africa, and in 1884 they sign a treaty with the Afar. The poet Arthur Rimbaud became a trader, and lived in Tadjoura from 1885 to 1886. He was the owner of a particular ship carrying weapons to be sold to the King of Shoa, cousin of the father of future Ethiopian Emperor Haile Selassie. In 1883 the French Somaliland (french: Côte française des Somalis) was officially fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East African Juniper
''Juniperus procera'' (known by the common English names African juniper, African pencil-cedar, East African juniper, East African-cedar, and Kenya-cedar) is a coniferous tree native to mountainous areas in Africa and the Arabian Peninsula. It is a characteristic tree of the Afromontane flora. Description ''Juniperus procera'' is a medium-sized tree reaching (rarely ) tall, with a trunk up to diameter and a broadly conical to rounded or irregular crown. The leaves are of two forms, juvenile needle-like leaves long on seedlings, and adult scale-leaves 0.5–3 mm long on older plants, arranged in decussate pairs or whorls of three. It is largely dioecious with separate male and female plants, but some individual plants produce both sexes. The cones are berry-like, 4–8 mm in diameter, blue-black with a whitish waxy bloom, and contain 2–5 seeds; they mature in 12–18 months. The male cones are 3–5 mm long, and shed their pollen in early spring.(Page archi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Climate
Alpine climate is the typical weather (climate) for elevations above the tree line, where trees fail to grow due to cold. This climate is also referred to as a mountain climate or highland climate. Definition There are multiple definitions of alpine climate. In the Köppen climate classification, the alpine and mountain climates are part of group ''E'', along with the polar climate, where no month has a mean temperature higher than . According to the Holdridge life zone system, there are two mountain climates which prevent tree growth : a) the alpine climate, which occurs when the mean biotemperature of a location is between . The alpine climate in Holdridge system is roughly equivalent to the warmest tundra climates (ET) in the Köppen system. b) the alvar climate, the coldest mountain climate since the biotemperature is between 0 °C and 1.5 °C (biotemperature can never be below 0 °C). It corresponds more or less to the coldest tundra climates and to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oceanic Climate
An oceanic climate, also known as a marine climate, is the humid temperate climate sub-type in Köppen classification ''Cfb'', typical of west coasts in higher middle latitudes of continents, generally featuring cool summers and mild winters (for their latitude), with a relatively narrow annual temperature range and few extremes of temperature. Oceanic climates can be found in both hemispheres generally between 45 and 63 latitude, most notably in northwestern Europe, northwestern America, as well as New Zealand. Precipitation Locations with oceanic climates tend to feature frequent cloudy conditions with precipitation, low hanging clouds, and frequent fronts and storms. Thunderstorms are normally few, since strong daytime heating and hot and cold air masses meet infrequently in the region. In most areas with an oceanic climate, precipitation comes in the form of rain for the majority of the year. However, some areas with this climate see some snowfall annually during winter. M ...

Climate
Climate is the long-term weather pattern in an area, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them. The climate of a location is affected by its latitude/longitude, terrain, altitude, land use and nearby water bodies and their currents. Climates can be classified according to the average and typical variables, most commonly temperature and precipitation. The most widely used classification scheme was the Köppen climate classification. The Thornthwaite system, in use since 1948, incorporates evapotranspiration along with temperature ...

Tree Planting
Tree-planting is the process of transplanting tree seedlings, generally for forestry, land reclamation, or landscaping purpose. It differs from the transplantation of larger trees in arboriculture, and from the lower cost but slower and less reliable distribution of tree seeds. Trees contribute to their environment over long periods of time by providing oxygen, improving air quality, climate amelioration, conserving water, preserving soil, and supporting wildlife. During the process of photosynthesis, trees take in carbon dioxide and produce the oxygen we breathe. In silviculture the activity is known as reforestation, or afforestation, depending on whether the area being planted has or has not recently been forested. It involves planting seedlings over an area of land where the forest has been harvested or damaged by fire, disease or human activity. Tree planting is carried out in many different parts of the world, and strategies may differ widely across nations and regions a ...

Forest Degradation
Forest degradation is a process in which the biological wealth of a forest area is permanently diminished by some factor or by a combination of factors. "This does not involve a reduction of the forest area, but rather a quality decrease in its condition. "The forest is still there, but with fewer trees, or less species of trees, plants or animals, or some of them affected by plagues. This degradation makes the forest less valuable and may lead to deforestation. Forest degradation is a type of the more general issue of land degradation. Deforestation and forest degradation continue to take place at alarming rates, which contributes significantly to the ongoing loss of biodiversity. Since 1990, it is estimated that some 420 million hectares of forest have been lost through conversion to other land uses, although the rate of deforestation has decreased over the past three decades. Between 2015 and 2020, the rate of deforestation was estimated at 10 million hectares per year, down f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afar People
The Afar ( aa, Qafár), also known as the Danakil, Adali and Odali, are a Cushitic-speaking ethnic group inhabiting the Horn of Africa. They primarily live in the Afar Region of Ethiopia and in northern Djibouti, as well as the entire southern coast of Eritrea. The Afar speak the Afar language, which is part of the Cushitic branch of the Afroasiatic family. Afars are the only inhabitants of the Horn of Africa whose traditional territories border both the Red Sea and the Gulf of Aden. History Early history The earliest surviving written mention of the Afar is from the 13th-century Andalusian writer Ibn Sa'id, who reported that they inhabited the area around the port of Suakin, as far south as Mandeb, near Zeila. They are mentioned intermittently in Ethiopian records, first as helping Emperor Amda Seyon in a campaign beyond the Awash River, then over a century later when they assisted Emperor Baeda Maryam when he campaigned against their neighbors the Dobe'a.

Leopard
The leopard (''Panthera pardus'') is one of the five extant species in the genus '' Panthera'', a member of the cat family, Felidae. It occurs in a wide range in sub-Saharan Africa, in some parts of Western and Central Asia, Southern Russia, and on the Indian subcontinent to Southeast and East Asia. It is listed as Vulnerable on the IUCN Red List because leopard populations are threatened by habitat loss and fragmentation, and are declining in large parts of the global range. The leopard is considered locally extinct in Hong Kong, Singapore, South Korea, Jordan, Morocco, Togo, the United Arab Emirates, Uzbekistan, Lebanon, Mauritania, Kuwait, Syria, Libya, Tunisia and most likely in North Korea, Gambia, Laos, Lesotho, Tajikistan, Vietnam and Israel. Contemporary records suggest that the leopard occurs in only 25% of its historical global range. Compared to other wild cats, the leopard has relatively short legs and a long body with a large skull. Its fur is marked with rosett ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desert Warthog
The desert warthog (''Phacochoerus aethiopicus'') is a species of even-toed ungulate in the pig family (Suidae), found in northern Kenya and Somalia, and possibly Djibouti, Eritrea, and Ethiopia. This is the range of the extant subspecies, commonly known as the Somali warthog (''P. a. delamerei''). Another subspecies, commonly known as the Cape warthog (''P. a. aethiopicus''), became extinct around 1865, but formerly occurred in South Africa. Evolutionary history Fossils have been found from the Holocene epoch showing that two divergent lines of warthogs (''Phacochoerus'' spp.) were in existence thousands of years ago. The ancestors of the present day common warthog (''P. africanus'') had a different number of incisors than the ancestors of the desert warthog (''P. aethiopicus'') line. During the late nineteenth century, ''P. aethiopicus'' became extinct in South Africa. Subsequently, study of mDNA as well as morphological analysis has shown that the East African population of ...

Buxus
''Buxus'' is a genus of about seventy species in the family Buxaceae. Common names include box or boxwood. The boxes are native to western and southern Europe, southwest, southern and eastern Asia, Africa, Madagascar, northernmost South America, Central America, Mexico and the Caribbean, with the majority of species being tropical or subtropical; only the European and some Asian species are frost-tolerant. Centres of diversity occur in Cuba (about 30 species), China (17 species) and Madagascar (9 species). They are slow-growing evergreen shrubs and small trees, growing to 2–12 m (rarely 15 m) tall. The leaves are opposite, rounded to lanceolate, and leathery; they are small in most species, typically 1.5–5 cm long and 0.3–2.5 cm broad, but up to 11 cm long and 5 cm broad in ''B. macrocarpa''. The flowers are small and yellow-green, monoecious with both sexes present on a plant. The fruit is a small capsule 0.5–1.5 cm long (to 3 cm i ...
