Alien Plant Invasion

• Alien invasive plants are considered a major threat to biodiversity
• These plants place great pressure on ecosystems, as they dominate the natural vegetation and out-compete it
• Alien invasive plants often replace large numbers (even total populations) of indigenous plants and thereby contribute to the loss of biodiversity
• Crop rotations or winter ploughing may adversely affect the environment of alien plants and inhibit their growth
• Strategies to control alien invasive plants include

  -Mechanical control

  -Chemical control

  -Biological control
