Animal Dispersal

Some plants have juicy fruit that animals like to eat.

The animal eats the fruit but only the juicy part is digested.

The stones and pips pass through the animal's digestive system and are excreted to form new plants. This can be far away from the parent plant.

Blackberry, cherry and apple seeds are dispersed in this way.

Birds also like to eat fruit and they help to disperse seeds to other areas through their droppings.

Mistletoe has sticky fruits which are attractive to birds. The sticky seeds stick to the bird's beak. They then rub their beaks clean on the bark of trees. The sticky seeds are left on the bark to grow into new mistletoe plants - mistletoe is a parasitic plant.

Squirrels collect nuts like acorns and bury them for winter food, but they often forget where they have buried them and these grow into new trees.


Some fruits like that of the burdock plant have seeds with hooks.

These catch on the fur of animals and are carried away.

Remember there are five ways that seeds are dispersed.

  1: Wind dispersal
  2: Water dispersal
  3: Animal dispersal
  4: Explosions
   5: Fire
