Demographic observations of mountain nyala Tragelaphus buxtoni in a controlled hunting area, Ethiopia
(Colorado State University. Libraries, 2015) Evangelista, Paul, author; Young, Nicholas, author; Swift, David, author; Wolde, Asrat, author; OMICS International, publisher
The highlands of Ethiopia are inhabited by the culturally and economically significant mountain nyala Tragelaphus buxtoni, an endemic spiral horned antelope. The natural range of this species has become highly fragmented with increasing anthropogenic pressures; driving land conversion in areas previously considered critical mountain nyala habitat. Therefore, baseline demographic data on this species throughout its existing range are needed. Previous studies on mountain nyala demographics have primarily focused on a confined portion of its known range where trophy hunting is not practiced. Our objectives were to estimate group size, proportion of females, age class proportions, and calf and juvenile productivity for a sub-population of mountain nyala where trophy hunting is permitted and compare our results to recent and historical observations. We collected four years of demographic data using direct point counts in a controlled hunting area and summarized the data using the R statistical software. Our results show that estimated proportion of females (0.63; 0.56-0.69) was similar to recent studies of non-hunted populations, but group size (3.74; 3.34-4.13), juvenile productivity (0.47; 0.35-0.62) and age class proportions (calves: 0.17 juveniles: 0.19 adults: 0.64) were considerably different. Our results are more similar to historical accounts than those in a national park. We demonstrate that the mountain nyala's population structure and health varies across its range and may relate to the different management strategies and policies. We recommend using similar methods for remaining under surveyed sub-populations of mountain nyala to inform conservation actions at the landscape scale.

Local knowledge of plants and their uses among women in the Bale Mountains, Ethiopia

Women's local ecological knowledge (LEK) is noted by many scholars to be unique and important for local conservation and development planning. Although LEK integration is inherent to ethnobotanical research, in Ethiopia, the knowledge-gender link has not been fully explored, and few studies focus on women's distinct plant knowledge. We catalogued rural women's knowledge of a wide range of plant uses in south-central Ethiopia, conducted through picture identification of 337 local plants. Fifty-seven plant species were identified, constituting 38 families, with the top five families being Lamiaceae, Solanaceae, Asteraceae, Rosaceae, and Pteridaceae. An array of uses were identified ranging from food, livestock and wildlife forage, to honey production and cosmetics. The most prevalent use noted (nearly 70%) was human medicine. This study reveals the important contribution of rural women's plant knowledge in the Bale Mountains, and the potential benefits of including this gender-distinct understanding of local flora in community-based conservation planning.

Mapping native and non-native riparian vegetation in the Colorado River Watershed
(Colorado State University. Libraries, 2018-10-24) Evangelista, Paul, author; Young, Nicholas, author; Vorster, Tony, author; West, Amanda, author; Hatcher, Emma, author; Woodward, Brian, author; Anderson, Ryan, author; Girma, Rebecca, author
Using remote sensing to map riparian vegetation, particularly single species such as tamarisk and Russian olive, requires georeferenced occurrence locations with estimations of foliar cover to train remote sensing-based models. This report details on the data, resources, methods and results to developing riparian vegetation, tamarisk and Russian olive distribution models along the Colorado River and its’ main tributaries. Change in riparian vegetation for Colorado River Basin was analyzed, finding an overall increase in riparian vegetation between 2006 and 2016. Also, an evaluation of the change map in known regions of tamarisk management showed that our models did identify a substantial decrease in tamarisk. The results of this study are a promising next step for project partners to utilize remote sensing to monitor the efficacy of management efforts throughout the Colorado River Basin and inform future management strategies.

Plant use in Odo-Bulu and Demaro, Bale region, Ethiopia

This paper reports on the plant use of laypeople of the Oromo in Southern Ethiopia. The Oromo in Bale had names/uses for 294 species in comparison to 230 species documented in the lower reaches of the Bale area. Only 13 species was used for veterinary purposes, or as human medicine (46). Plant medicine served mostly to treat common everyday ailments such as stomach problems and diarrhea, for wound treatment and as toothbrush-sticks, as anthelmintic, for skin infections and to treat sore muscles and. Interestingly, 9 species were used to treat spiritual ailments and to expel demons. In most cases of medicinal applications the leaves or roots were employed. Traditional plant knowledge has clearly declined in a large part of the research area. Western style health care services as provided by governments and NGOs, in particular in rural areas, seem to have contributed to a decline in traditional knowledge, in part because the local population simply regards western medicine as more effective and safer.
