Invasive Species Management
Monitoring, controlling, and preventing invasive species that threaten Kenya's biodiversity
Plant Invasives
Prosopis juliflora (Mathenge)
Invasive shrub affecting arid and semi-arid areas, particularly in northern Kenya. Forms dense thickets that displace native vegetation.
Water Hyacinth (Eichhornia crassipes)
Aquatic weed severely affecting Lake Victoria, blocking waterways and affecting fish populations.
Lantana camara
Toxic ornamental plant spreading in wildlife areas, poisonous to grazing animals.
Animal Invasives
Nile Perch (Lates niloticus)
Large predatory fish introduced to Lake Victoria, causing decline of endemic cichlid species.
Common Carp (Cyprinus carpio)
Introduced fish species affecting aquatic vegetation and water quality in lakes and rivers.
Feral Cats and Dogs
Domestic animals gone wild, predating on native small mammals and birds.
Control and Management Strategies
Mechanical Control
- Manual removal of invasive plants
- Use of machinery for large infestations
- Physical barriers and traps
Biological Control
- Introduction of natural predators
- Use of specific herbivores
- Pathogen-based control methods
Chemical Control
- Selective herbicide application
- Targeted poisoning programs
- Soil treatment methods
Environmental Impact
Invasive species pose significant threats to Kenya's ecosystems:
- Biodiversity Loss: Displacement of native species and disruption of food chains
- Economic Impact: Reduced agricultural productivity and increased management costs
- Ecosystem Services: Degradation of water quality, soil stability, and pollination
- Tourism: Reduced aesthetic value and wildlife viewing opportunities
