What was the effect cyclone Tracy had on plants and animals?

Answer 1

When Cyclone Tracy hit, it caused considerable damage to the environment, and hence to the plants and animals.

Water supplies were down as Darwin's supply was contaminated and there were no clean supplies. Sewerage lines were cut, resulting in a lack of sanitation, and poisons therefore leached out into the environment, which affected living organisms. Surprisingly, there was not a lot of drenching rain or storm surge associated with Cyclone Tracy, so none of the usual problems resulted from that quarter.

Trees were uprooted, and animal habitats destroyed. Witnesses reported absolute silence the following morning, signalling the loss of the majority of bird life at that time. As with any such natural disaster, the food chain was broken, and it was many months before food chain order was reestablished among the various species. The beaches were strewn with dead marine or coastal-dwelling creatures. Many coral reefs, fish and animals were damaged and are still recovering.
