A thornbush is a type of shrub characterized by its sharp, pointed thorns. These thorns serve as a defense mechanism against herbivores, helping the plant to survive in various environments. Thornbushes can be found in many regions around the world, often thriving in dry or arid climates. Common examples of thornbushes include blackberry and hawthorn. They can provide important habitats for wildlife, offering shelter and food sources. Additionally, thornbushes can play a role in soil conservation by preventing erosion with their root systems.
