Assessing the Sustainability of Different Small-Scale Livestock Production Systems in the Afar Region, Ethiopia
Atanga, Ngufor L.; Treydte, Anna C.; Birner, Regina (MDPI, 2013-12-02)Livestock production is a key income source in eastern Africa, and 80% of the total agricultural land is used for livestock herding. Hence, ecological and socio-economically sustainable rangeland management is crucial. Our ... -

Crops like soy bean, oil palm and rubber have led to drastic changes in land cover over the past decades, thereby ... -
Can diverse herbivore communities increase landscape heterogeneity? Comparing wild and domestic herbivore assemblages in a South African savanna
Baumgartner, Sabine A.; Treydte, Anna C.; Grant, Catharina C.; Rooyen, Jacques van (Elsevier, 2015-02)The structure and composition of woody and grassy vegetation in savannas is strongly influenced by herbivores. In recent decades, the proportion of browsers has declined across African savannas in favour of more grazers, ... -
Can rangelands gain from bush encroachment? Carbon stocks of communal grazing lands invaded by Prosopis juliflora
Birhane, Emiru; Treydte, Anna C.; Eshete, Abeje; Solomon, Negasi; Hailemariam, Mengsteab (Elsevier Ltd., 2017-06)Rangeland ecosystems are rapidly declining due to overgrazing and bush encroachment. Little is known about how important bush encroachment is for climate change mitigation. We estimated woody plant biomass at different ... -
Carbon stocks and sequestration potential of dry forests under community management in Tigray, Ethiopia
Solomon, Negasi; Birhane, Emiru; Tadesse, Tewodros; Treydte, Anna C.; Meles, Kiros (Springer Open, 2017-06-20)Introduction: Forests form a major component of the carbon (C) reserves in the world’s ecosystems. However, little is known on how management influences C stocks of woody vegetation, particularly in dry areas. We ... -
Effects of clipping and irrigation on carbon storage in grasses: implications for CO2 emission mitigation in rangelands
Tuffa, Samuel; Hoag, Dana; Treydte, Anna C. (Taylor & Francis Online, 2018-04-03)Understanding how individual grasses respond to herbivory and rainfall has been hampered by the difficulty of quantifying above- and belowground carbon (C) storage in grasses. Particularly by restoring degraded rangelands ... -
Enhanced use of beneath-canopy vegetation by grazing ungulates in African savannahs
Treydte, Anna C.; Riginos, Corinna; Jeltsch, Florian (Elsevier B.V., 2010-12)The cover of large trees in African savannahs is rapidly declining, mainly due to human land-use practices. Trees improve grass nutrient quality and contribute to species and structural diversity of savannah vegetation. ... -
Herbaceous Forage and Selection Patterns by Ungulates across Varying Herbivore Assemblages in a South African Savanna
Treydte, Anna C.; Baumgartner, Sabine A.; Heitkönig, Ignas M. A.; Grant, Catharina C.; Getz, Wayne M. (PLOS ONE, 2013-12-16)Herbivores generally have strong structural and compositional effects on vegetation, which in turn determines the plant forage species available. We investigated how selected large mammalian herbivore assemblages use and ... -
The importance of nutrient hotspots for grazing ungulates in a Miombo ecosystem, Tanzania
Mayengo, Gabriel; PielI, Alex K.; Treydte, Anna C. (PLOS ONE, 2020-03-30)While movement patterns of grazing ungulates are strongly dependent on forage quality their use of nutrient hotspots such as termite mounds or grazing lawns has rarely been quantified, especially in savanna ecosystems where ... -
