Mt Ziqualla crater is covered by a large forest protected by two indigenous religions a. The area is of high conservation value, it is one of the Important Bird Areas of Ethiopia, and has one of the last remaining patches of more or less undisturbed forest in the region. Currently under limited threat from local and religious communities.
Mount Ziqualla is a large extinct volcano dominating the western part
of the Rift Valley to the East of Addis Ababa. The crater, about 1 km across,
is situated about 1000m above the surrounding plain and harbours a lake about
100m below the crater rim. All outer slopes of the volcano are steep and often
dissected by deep gullies.
The natural vegetation, mainly forest, only remains
inside the crater and in a few deep gullies below the summit, however in former
times the whole mountains would have been mainly forested. Now, the remaining
vegetation is dominated by secondary scrub with much cultivation to the western
and southern upper slopes of the crater. To the North, on the crater rim and
the upper slopes, there is a large plantation of Cupressus lusitanica established in the 1960s. The zone around the
crater lake is open grassland.
The Orthodox monastery has two churches situated on
the northern rim of the crater whilst the traditional Oromo sacred site is near
the forest edge to the south of the lake. In former times more churches existed
around the crater, one site is easily identifiable at the very summit of the
crater rim. The monastery community is situated right below the two churches on
the outer upper slopes of the crater.
Ziqualla has been an important religious site for
many centuries including a major destination for pilgrims. Although it is often
stated that deforestation mainly occurred at the end of the 20th
century, aerial photographs suggest that much of the tree cover had disappeared
by the 1960s. Photographs of the crater taken in the 1920s indicate that the
tree cover then was not as extensive as it is today.
As indicated by the number of scientific studies carried out on Mt
Ziqualla, the area is of high conservation value. Over 200 species of plants
have been recorded inside the crater. It is one of the Important Bird Areas of
Ethiopia.
Both religious communities take an active part in
preserving this unique site.
Inner crater with lake, grassland and south-eastern forested
slopes.
Branch cutting (Juniper) and dense ground vegetation with a small Erica arborea in left foreground.
Little cutting of trees is currently taking place,
more noticeable is the cutting of branches near the monastery. Much of the area
in the vicinity of Oromo traditional site is pristine and contains many tall Erica arborea. However, due to the lack
of tree resources in the surrounding landscape tree harvesting is a great
potential threat, which at the moment is only prevented by the presence of a
number of armed guards. Currently, wood harvesting is not a problem but in the
long-term this remains the single most important potential threat. The
agroforestry project around the base of the volcano should help alleviate this
threat.
The Cupressus
lusitanica is regenerating freely and the plant is spreading into Juniperus forest, this process is being
facilitated by the steep slopes enabling cones to roll downhill. It establishes
successfully under the semi-open canopy of juniper.
Fire is a serious potential problem. In 2001 a large
fire, intentionally lit, raged up the outer slope of the mountain.
In order to reduce future problems, the spread of Cupressus lusitanica should be
controlled. Mature trees situated on the inner crater slopes should be removed
to prevent the fruit from dispersing downhill.
The rapidly increasing monastery population will
undoubtedly increase the demand for wood products and thus the need for tree
cutting. The use of the exotic timber should be encouraged and the large Cupressus lusitanica, if managed
properly, could provide the necessary timber resources needed by both religious
and local communities.
