Question

which activity is a method of habitat restoration?
cleaning up after environmental disasters
allowing trees to grow naturally
farming techniques like terrace farming and tree belts
creating a reservoir to prevent flooding

Explanation:

Habitat restoration aims to recreate or enhance natural habitats. Allowing trees to grow naturally helps rebuild forest habitats, which is a key part of habitat restoration. Cleaning up after disasters (focuses on cleanup, not habitat rebuilding), farming techniques (agricultural practices, not habitat restoration), and creating a reservoir (flood control, not habitat - related) don't fit as well.

Answer:

allowing trees to grow naturally
