Flora Guassa supports important and endemic plant species including Guassa grass,
giant lobelia,
Erica moorlands,
Helichrysum and
Alchemilla species. The Afro-montane vegetation of the Guassa Area varies with altitude and is a key attraction of the area. Other common plant species found in the area include
Carex monostachya,
Carex fischeri and
Kniphofia foliosa of the family
Asphodelaceae. Climbing in altitude,
Euryops-Alchemilla shrubland occurs over 3,200 meters on flat, gentle slopes and well-drained areas. The shrubby vegetation of
Euryops pinifolius (
Compositae family is extensively used as firewood by the communities living adjacent to the Guassa Area. Above 3,200 meters,
Euryops-Festuca grassland is usually interspersed with scattered structures similar to
Mima mounds that can reach a height of 1.5 meters and a diameter of 5 to 10 meters. These mounds consist of highly organic and deep soil. They are made by rodents, the most important of which is the
common mole rat. As the altitude increases, the vegetation changes abruptly to
Helichrysum-Festuca type of grassland followed by
Erica moorland. The
torch lily or
red-hot poker (
Kniphofia spp.) covers entire hillsides with its flame-colored flowers between June and November. The palm-like giant lobelia (
Lobelia rhynchopetalum) is most spectacular and reaches up to 12 meters in height.
Fauna Mammals The Guassa area harbors nine (23%) of the
endemic mammals of
Ethiopia, including the
Ethiopian wolf, the
Gelada and the
Ethiopian highland hare. The
Ethiopian wolf is legally protected and with a total world population of less than 450 is the most endangered canid in the world. With six packs of wolves, the Guassa area is a key population of the species. The
gelada is the only living member of the once widespread genus
Theropithecus and is only found in the highlands of northern
Ethiopia. They live in large groups reaching up to 400 individuals where the spectacular male guard harems of females. Other mammals of the area include
klipspringers,
jackals,
leopards,
spotted hyenas,
civets and
servals.
Avifauna 114 bird species have been recorded in the Guassa Area: 12% of the 862 species of birds in
Ethiopia. The area is also home to a multitude of birds of prey and serves as a wintering ground for 38 species of
Palearctic and intra-African
migratory birds.
