ABSTRACT Prosopis juliflora (Sw.) DC is a woody plant from the Americas that has dispersed worldwide via human intervention. Typically introduced with good intentions, Prosopis often proliferates and degrades native ecosystems. Prosopis first appeared in the Allideghi Wildlife Reserve (AWR) of northeastern Ethiopia in 1997. In 2005–2006 we determined: (1) patterns of Prosopis dispersal and establishment using global-positioning system mapping and seed-bank assessments; (2) impacts of Prosopis… 
Seed germination and early seedling survival of the invasive species Prosopis juliflora (Fabaceae) depend on habitat and seed dispersal mode in the Caatinga dry forest
How seed dispersal ecology and soil conditions collectively affect seed germination, early seedling performance and consequently the P. juliflora invasive potential is examined.
Influence of invasive Prosopis juliflora on the distribution and ecology of native blackbuck in protected areas of Tamil Nadu, India
Baseline data on intrinsic–extrinsic determinants of spatial distribution of flagship species helps wildlife managers develop their management strategies. Globally, large herbivores are in range
A preliminary assessment of the extent and potential impacts of alien plant invasions in the Serengeti-Mara ecosystem, East Africa
This article provides a preliminary list of alien plant species in the Serengeti-Mara ecosystem in East Africa. The list is based on broad-scale roadside surveys in the area and is supplemented by
Implications of land use/land cover dynamics and Prosopis invasion on ecosystem service values in Afar Region, Ethiopia.
Modelling the current fractional cover of an invasive alien plant and drivers of its invasion in a dryland ecosystem
Villages and linear landscape structures were found to be more important drivers of future Prosopis invasion than environmental variables, such as climate and topography, suggesting that prosopis is likely to continue spreading and increasing in abundance in the case study area if left uncontrolled.
A preliminary assessment of the presence and distribution of invasive and potentially invasive alien plant species in Laikipia County, Kenya, a biodiversity hotspot
Invasive alien species are those plants and animals that have been introduced by people, either intentionally or unintentionally, outside of their natural range or outside of their natural dispersal
An assessment of the distribution and potential ecological impacts of invasive alien plant species in eastern Africa
With a few exceptions, comprehensive lists of alien plants that invade natural ecosystems are lacking in sub-Saharan Africa. Some available lists are either preliminary or localised, or focus on
Processes and drivers of Prosopis invasions in Eastern Africa
The lack of genetic differentiation between some species from the native range supports the notion that hybridization between allopatric species may occur frequently when they are cointroduced into new ranges.


Impacts of Pastoralists on Woodlands in South Turkana, Kenya: Livestock‐ Mediated Tree Recruitment
The early survival and growth advantages of the corral environment appear to stabilize the reproductive patterns of A. tortilis in this arid ecosystem, where successful recruitment in noncorral sites may be restricted to the few years with high rainfall.
Responses of desert grassland vegetation to mesquite removal and regrowth
Abstract The purpose of this study was to determine the long-term response of understory vegetation in the desert grassland of southeastern Arizona, USA, to removal and regrowth of mesquite Prosopis
Forestry Trees as Invasive Aliens
There is an urgent need to integrate the various means available for reducing the negative impacts of current invaders and to implement protocols to regulate the translocation of species that are known to be invasive.
Endangered Grevy’s zebra in the Alledeghi Wildlife Reserve, Ethiopia: species distribution modeling for the determination of optimum habitat
The present study employed the maximum entropy model (Maxent), a species distribution modeling approach, to determine the geographic extent of habitat and seasonal distribution of Grevy’s zebra in the Alledeghi Wildlife Reserve, Ethiopia, and to use this information to determined the optimum demarcation of conservation boundaries.
Prosopis juliflora Invasion and Rural Livelihoods in the Lake Baringo Area of Kenya
Global concern about deforestation caused by fuelwood shortages prompted the introduction of Prosopis juliflora to many tropical areas in the 1970s and 1980s. P. juliflora is a hardy nitrogen-fixing
Seed Bank and Understorey Species Composition in a Semi-arid Environment: The Effect of Shrub Age and Rainfall
Understorey vegetation in patches of Retama sphaerocarpa shrubs in semi-arid environments is dependent on the overstorey shrub life history and the eAect of the canopy on understorey species diversity in the field and its relationships with the soil seed bank is investigated, suggesting that the soil Seed Bank is rather uniform and that the shrub canopy strongly selects which species appear in theunderstorey.
Mapping Current and Potential Distribution of Non-Native Prosopis juliflora in the Afar Region of Ethiopia
It is demonstrated that time-series of MODIS vegetation indices and species occurrence points can be used with Maxent modeling software to map the current distribution of P. juliflora, while topo-climatic variables are good predictors of potential habitat in Ethiopia.
The value of Acacia and Prosopis in arid and semi-arid environments
The promotion of more lesser-known species in planting programmes would help to conserve the valuable diversity in both Acacia and Prosopis.
The potential consequences of pollinator declines on the conservation of biodiversity and stability of food crop yields
The work group encourages increased education and training to ensure that both the lay public and resource managers understand that pollination is one of the most important ecological services provided to agriculture through the responsible management and protection of wildland habitats and their populations of pollen-vectoring animals and nectar-producing plants.
