Hydrology

The Bale Mountains play a vital role in climate control of the region by attracting large amounts of

rainfall, which has obvious implications for livestock and agricultural production. Some 600 - 1,000 mm fall annually in the lower altitude areas, while 1,000 - 1,400 mm fall in areas of higher altitude, and over 12 million people from Kenya, Somalia and Ethiopia are dependent on water from the Bale massif. A total of 40 rivers rise in the BMNP area, contributing to five major rivers: the Web, Wabe Shebele, Welmel, Dumal and Ganale. Additionally, the Bale massif is the source for many springs in the lowlands, which are of paramount importance as they are the only source of water year-round. People living south of the national park are completely dependent on good management of the water resources from the highland areas. If the flow of these rivers is altered in any way – through deforestation,
overgrazing Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature res ...
of pastures and/or over abstraction for irrigation (all of which are occurring at present) – a highland/lowland imbalance results with loss of perennial water in the lowlands. If such a situation arises, the dry season range of the people and their livestock reduces dramatically and they concentrate about whatever water source remains. It is widely recognized that such uneven distribution of people and livestock leads to rapid and lasting degradation. The people are, therefore, likely to become increasingly food-aid dependent if the water catchment areas of the Bale Mountains are insufficiently protected. There is already evidence that over abstraction of water in the Bale Mountains is occurring. Furthermore, two rivers emanating from Bale, the Wabe Shebele and Yadot, (tributary of the Ganale) have hydroelectric schemes. The dam on the Yadot River supplies electricity to Delo-Mena, while the dam on the Wabe Shebele provides electricity to the Bale area. Lastly, there are numerous natural mineral water springs, locally called horas, which provide an essential source of minerals for livestock. The mineral springs within the park are valued for their high mineral content (

), and local pastoralists believe that in order to maintain good health and milk production their livestock must be given hora water. They will drive their livestock for up to two days to reach the hora springs. It is increasingly apparent, however, that the hora springs have become an excuse for local people to enter the park to gain access to better grazing areas.


Climate

Temperatures vary widely throughout BMNP: on the plateau, daytime temperatures are usually around 10 °C (50 °F) with strong winds; in the Gaysay Valley average daytime temperatures are around 20 °C (68 °F), and the Harenna Forest is around 25 °C (77 °F). However, the weather changes frequently and sometimes drastically. In elevations over 3,000 meters, night frosts are common. The rainy season is from May until November.


Ecology


Habitats

The park is divided into five distinct and unique habitats: the Northern Grasslands (Gaysay Valley), Northern Woodlands (Park Headquarters), Afro-alpine Meadows (Sanetti Plateau), Erica Moorlands, and the
Harenna Forest The Harenna Forest is a montane tropical evergreen forest in Ethiopia's Bale Mountains. The forest covers the southern slope of the mountains, extending from 1450 to 3200 meters elevation. The Bale Mountains are in Ethiopia's Oromia Region, and fo ...

Avifauna

The Bale Mountains are home to over 282 species of birds, including nine of the 16 species endemic to Ethiopia. Furthermore, over 170 migratory birds have been recorded within the park. Bale Mountains National Park is home to almost every highland Abyssinian and Ethiopian endemic. With over 863 species of birds recorded, representing approximately 9.5% of the world's bird diversity and 39% of the bird species in Africa, Ethiopia is often considered one of the most avifaunal-rich countries in Africa. Sixteen of Bale's bird species are endemic to Ethiopia. Due to the diversity and density of rodents, the Bale Mountains are also an extremely important area for residents as well as wintering and passing raptors. Ethiopian endemic birds in Bale Mountains include blue-winged goose (''Cyanochen cyanoptera''),

Herpetofauna

Ethiopian rare endemic reptiles that are newly discovered in the Bale Mountains forested areas include Ethiopian House snake (''Lamprophis erlangeri''), Ethiopian mountain adder (''Bitis parviocula''), Bale two-horned chameleon (''Trioceros balebicornutus''), Harenna hornless chameleon (''Trioceros harennae''), Beardless Ethiopian montane chameleon (''Trioceros affinis''), and Wolfgang Böhme's Ethiopian Chameleon (''Trioceros wolfgangboehmei''). At least 7 species of endemic Amphibians are discovered in forested swampy areas and Bale Mountains National park plateaus. Ethiopian burrowing tree frog (''Leptopelis gramineus''), Erlanger's Grassland frog (''Ptychadena erlangeri'') and Neumann's Grassland frog (''Ptychadena neumanni'') are commonly rare within these habitats. However, other amphibians species lives within the areas of Bale Mountains such as Bale Mountain Frog (''Ericabatrachus baleensis''),

system known as the Godantu system, a key feature of traditional human use of the Bale Mountains. In this system, livestock, particularly cattle, are sent to higher grazing grounds during the months when crops are growing in lower altitudes or into the forest for shade during the dry season. However, this should not be confused with the cattle movements that are a consequence of the loss of grazing land outside of the park, thus forcing cattle into the park to graze. Bale houses are circular in shape and locally referred to as “mana citaa”. Juniper and sometimes eucalyptus are used to make the walls and roof. The roof is covered with thatched grass cut from “citaa” (tussock grass) or stubble, especially barley, and supported by a wooden pillar, which stands in the middle of the floor. The house is divided into portions by walls made of bamboo or mud mixed with the stubble of barley or grass.


Threats

Bale Mountains National Park is faced with many threats associated with an ever-developing and increasingly populated Ethiopia. One of the biggest threats to the park is grazing. For example, within the Web Valley, a prime Ethiopian wolf habitat, cattle density is estimated at 250 per square kilometer. Other threats include increasing settlements within the park. Currently, over 40,000 people live within the park's boundaries, increasing pressure on the natural resources of the area and diminishing natural habitats of wild animals. With these settlements come domestic dogs, which pose a great threat to the Ethiopian wolf. Dogs transmit rabies and canine distemper, and in 2010 killed 106 individuals (approximately 40% of the Bale population of Ethiopian wolves). Other serious threats include the use of the wolf habitat by livestock for grazing which significantly reduces the availability of rodent prey. Over 12 million people, their livestock, and the environment in the south of Ethiopia as well as neighboring

Conservationists suggest that if conservation efforts in the Bale Mountains are not successful and people continue to exploit the resources in an unsustainable way, more species of mammal would go extinct than in any other area of equivalent size on the planet.
