So, we've been talking about forest fires and, usuallywhen the forest fire occurs, the animals in the areawill of course run away, flee as fast as they can soit's not to get hurt by the flames.
Some animals though actually benefit from forestfires and so will seek them out. Because forest firescan be helpful can help them fulfills certain survivalneeds. Let' s discuss two benefits forest fires can help these animals.
One benefit is that they can make it easier for predators to find food? A forest fire will forceanimals out of their hiding places and out into the open which predators take advantage of.Because fleeing animals are much easier to catch than they normally are when they are hiding.For example, scientists have observed wild turkeys doing this? These birds will go to the edgeof forest fire and wait there in order to catch out the insects running out of the burning forest,which is a much easier way to catch insects than the normal way of pecking for themunderground.
Another benefit forest fires can have is to help provide a good place for the development of theyoung animals. Forest fires can make an otherwise harmful environment more suitable fortheir development.For example, some trees in the forest are poisonous to beetles. They havespecial chemical that keep beetles away. But after a fire, beetles will seek up these trees becausetrees are died and beetles are able to lay their eggs in the tree without being hurt by thechemical. The young beetles use the trees' nourishment until they are mature into adultbeetles.
According to the lecture, the professor talked about two benefits forest fires for certain animals.
The first one is that the hiding animals are forced to run away. The predators can easily find their food in open area compared to wait for their food. For example, wild turkeys can chase the insects at the edge of a forest fire and catch them easily on the ground.
The another benefit is that young animals can get a suitable place to grow. For example, toxic chemical is included in some trees, which can threaten beetles. But the forest fires turn the dead trees to be the beetle’s homeland. The beetles can lay eggs in the trees without harmful chemical and young beetles can utilize the nutrition to grow into mature ones.
