  • The dense bushes and the tall grasses provide animals of the forests with food, shelter and from carnivores.
  • The animals in the forest disperse the seeds of certain plants and help in the regeneration of plants.
  • When it rains in the forest, the raindrops drip slowly over branches of the shrubs and herbs
  • Water do not stagnate in the forest and forest is a natural absorber of rain water which allows the rain water to seep and thus maintains the water table.
  • Forests absorb the noise of nearby highways and keep the surrounding areas cool because of heavy rainfall they receive.
