Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. [2] Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment [3] (suspected of being one of the ...
e. Conservation in Australia is an issue of state and federal policy. Australia is one of the most biologically diverse countries in the world, [1] with a large portion of species endemic to Australia. Preserving this wealth of biodiversity is important for future generations. 25% of Australia is managed for conservation.
Jarrah Forest, also known as the Southwest Australia woodlands, is an interim Australian bioregion and ecoregion located in the south west of Western Australia. [2] [3] The name of the bioregion refers to the region's dominant plant community, jarrah forest – a tall, open forest in which the dominant overstory tree is jarrah (Eucalyptus marginata).
Habitat degradation, fragmentation, and pollution are aspects of habitat destruction caused by humans that do not necessarily involve over destruction of habitat, yet result in habitat collapse. Desertification , deforestation , and coral reef degradation are specific types of habitat destruction for those areas ( deserts , forests , coral reefs ).
Wildlife crossings are a practice in habitat conservation, allowing connections or reconnections between habitats, combating habitat fragmentation. They also assist in avoiding collisions between vehicles and animals, which in addition to killing or injuring wildlife may cause injury or death to humans and property damage.
Many factors are thought to be responsible for the dramatic decline of this species in Australia, including habitat fragmentation, erosion and sedimentation of soil, insecticides and fertilisers contaminating water systems, [42] the introduction of predatory fish, and alteration of drainage regimes.

Conservation status is a measure used in conservation biology to assess an ecoregion's degree of habitat alteration and habitat conservation. It is used to set priorities for conservation. Ecoregion Conservation Status refers to the assessment and categorization of the ecological health, biodiversity, and threats faced by distinct geographic areas
The SLOSS debate was a debate in ecology and conservation biology during the 1970's and 1980's as to whether a s ingle l arge o r s everal s mall (SLOSS) reserves were a superior means of conserving biodiversity in a fragmented habitat. Since its inception, multiple alternate theories have been proposed. There have been applications of the ...
