Endangered Plants · Botany

Why is 'Habitat Fragmentation' particularly dangerous for endangered forest plants?

  1. It increases the amount of available sunlight.
  2. It makes it easier for plants to spread their seeds.
  3. It eliminates all herbivores from the area.
  4. It isolates populations and reduces genetic exchange.
Show answer and explanation

Correct answer: It isolates populations and reduces genetic exchange.

When large habitats are broken into small, isolated patches, plant populations become separated. This leads to inbreeding depression and makes the species more vulnerable to local extinction from disease or weather events.
