Species profile
Mathenge
Mathenge, also known as Prosopis juliflora, transforms rangelands, suppresses native vegetation, affects livestock movement, and deepens livelihood pressure in already fragile dryland systems.
Overview
Mathenge in the African context
Prosopis is a thorny woody invasive that can dominate drylands and rangelands, crowding out native vegetation and making land use more difficult. In Kenya, Prosopis is widely known as Mathenge.
Spread
It spreads through seed dispersal, livestock movement, flood events, and its capacity to establish in stressed dryland conditions.

Why it matters in Africa
Why this species deserves serious attention
These points connect the species to real African systems, livelihoods, and institutional pressures.
Point 1
Dryland and pastoral regions are already under climatic and livelihood pressure.
Point 2
Dense invasion can turn a land management issue into a social and economic one very quickly.
Point 3
The species shows why eradication, utilization, and landscape restoration must be considered together.
Impacts
Ecological, livelihood, and institutional impacts
These are the main ways this species affects real systems, communities, and response capacity.
Reduces grazing quality and changes access routes for animals and people.
Suppresses native dryland vegetation and alters ecosystem structure.
Can turn rehabilitation plantings into dense invasive stands when governance, use, and long-term control are weak.
Creates management burdens that are difficult to sustain without local buy-in and long-term planning.
Response and management options
Approaches that can support credible response
No single tool solves the problem. These are the main management options associated with this species.
Mechanical removal and controlled thinning
Utilization strategies linked to local livelihoods
Landscape restoration and reseeding
Integrated dryland management and governance
Response summary
Control depends on sustained removal, landscape restoration, adaptive grazing management, and practical community use strategies for Mathenge, also known as Prosopis juliflora.
