At the request
of Rhino Ark, UNEP, Kenya Wildlife Service, Rhino Ark and the Kenya Forests
Working Group undertook an aerial survey of the destruction of the Aberdare
Range forests The Aberdare forests are one of Kenya's five main "water towers"
and play a critical role in supporting the country's economy. They are the
main source of water for Nairobi. 55 percent of Kenya's electricity is generated
by water flowing from the Aberdares and Mt. Kenya. The survey of the Aberdare
forests was undertaken in the second half of 2002. It covered all forest reserves
of the Aberdare Range ecosystem, as well as any forested area located within
the Aberdare National Park. It required some 61 hours of flight time. The
survey revealed that the forests are heavily impacted by illegal charcoal
production in most areas on the western, southern and south-eastern slopes.
Illegal logging of indigenous trees is a major concern across the entire Range,
in particular the logging of Cedar trees that extensively affect the northern
and western slopes. Illegal cultivation of crops and settlements present a
major threat to the integrity of the ecosystem, having already led to the
destruction of well over 6,100 hectares.
Southern
slopes of the Aberdare Range
Illegal activities
affect the entire mixed broadleaf forest. The moist Ocotea forests that cover
most of the southern slopes are undergoing serious destruction caused by the
intensive charcoal production and illegal logging. During the survey, over
10,000 charcoal kilns were counted. In the drier forest that covers the escarpment
bordering the Rift Valley, charcoal production had led to the destruction
of over 80 percent of the forest canopy in many areas. Over 2,800 recently-logged
indigenous trees were counted. Although Camphor trees used to be a dominant
species in most areas on the southern slopes, only 272 recently-logged Camphor
trees were counted. Past depletion of the Camphor stand explained this low
number. Livestock grazing presents a major threat to forest regeneration,
with over 5,700 head counted on the southern slopes.
Western
slopes of the Aberdare Range
Logging and charcoal
production also impact heavily on the western slopes. Over 2,000 recently-logged
Cedar trees were counted, as well as some 1,100 other indigenous trees, in
addition to over 3,500 charcoal kilns. The cumulative impacts of illegal logging
and charcoal production has opened up most of the forest areas that cover
the steep slopes along the western fault escarpment and the ridges emanating
from Kinangop peak. Large tracts of forests have been destroyed and irregularly
converted into settlements, including 4,475 hectares around Kipipiri and 1,104
hectares in Ragia forest.
Northern
slopes of the Aberdare Range
The northern
tip of the Range is mostly grassland with scattered clusters of trees. These
remaining clusters, located outside the fence, are the target of illegal activities,
mainly charcoal production and logging of Cedar. Well over 5,100 heads of
livestock were observed in that area, most likely leading to overgrazing and
inhibiting regeneration.
Eastern
slopes of the Aberdare Range
Logging of indigenous
trees and illegal cultivation are the two major threats to the eastern slopes.
Over 1,800 recently logged Cedar trees were recorded, as well as some 2,750
other indigenous trees. In the northern block of South Laikipia Forest Reserve,
past logging activities has led to the removal of over 90 percent of the forest
cover. Some 49 cultivated fields in the indigenous forests were found near
Chinga. In addition, the survey identified 16 small marijuana fields, most
of them being planted or partially planted. The majority of the clear felled
forest plantations under the Shamba-system have not been replanted with young
trees, as required by the normal rotation management.
