Bushfires
Bushfires are fires that burn natural vegetation in forests, grasslands and woodlands. Many are due to lightning strikes but some have been known to be lit by humans. Fire has a major impact on the environment because it promotes the germination of many plant species. Manu plants are adapted to survive fires and even benefit from it.
Drought
Drought is an extended period of no rainfall in an area. Drought can impact ecosystems by increasing the death rate in an area, causing some of the species in the area to become extinct. Death of producers from lack of water will remove a resource for animals who rely on them for food, shelter and nesting sites.
Floods
Floods are events where water temporarily covers land which is not usually covered with water. Heavy rains can result in rivers overflowing and widespread flooding in some places.
