Terrestrial animals — birds

Overall, bird species populations across much of Australia are in decline. Some areas experience inconsistent trends with some species increasing and some decreasing in the tropical savanna, Brigalow Belt and Tasmania region. Rainforest-dependent species appear to be increasing

Comments

The 2016 assessment relies on an information base similar to the one used in 2011, and the grade and trend can be considered comparable with 2011.

Topics

Relatively resilient historically but threatened species make up a large proportion of known species in some areas. Large fluctuations in numbers over the past decade due to climate variation. Several states raise concerns about recent declines, especially in forests and woodlands, and the potential for legacy effects from past pressures that have not yet been seen

Approach/Process

Assessment grades and trends were determined by the authors through a qualitative assessment of data and information from publicly available or published reports and scientific papers referenced in the text, information obtained from jurisdictional State of Environment reporting and/or information supplied directly from the jurisdictions.

Data/Information sources

References cited in text.

Relevant information, references and assessment summaries in the Coasts and Marine Environment chapters.

 

Jurisdictional State of Environment reports including specific indicators for invasive species state and trend:

 

  • Australian Capital Territory 2015
  • South Australia 2013 and the South Australian NRM Report Cards 2015
  • New South Wales 2015
  • Victoria 2013

Data collection and quality vary across jurisdictions.

 

Information provided directly by state and territory government departments. The scope and presentation of material provided vary across jurisdictions.

 

 

Comments

The information base used for the 2016 assessment should be considered only somewhat comparable to 2011.

Topics

Nationally there are a number of coastal places and areas on the continental shelf and upper slope where the condition of some biodiversity is very poor, as a result of the effects of specific human activities

Assessment Summary Key

Grades

Very good

The vast majority of taxa appear to have good prospects for long-term survival and any declines are limited
in spatial extent and severity and are unlikely to threaten future viability of taxa

Good

Most taxa appear to have good prospects for long-term survival, although a small proportion have suffered
declines that might threaten long-term survival

Poor

A significant proportion of taxa have suffered declines across most or all of Australia that potentially threaten
their long-term persistence

Very poor

A large proportion of taxa have suffered declines across most or all of Australia

Recent Trends

  • Improving

  • Stable

  • Deteriorating

  • Unclear

Confidence

  • Adequate: Adequate high-quality evidence and high level of consensus

  • Somewhat adequate: Adequate high-quality evidence or high level of consensus

  • Limited: Limited evidence or limited consensus

  • Very limited: Limited evidence and limited consensus

  • Low: Evidence and consensus too low to make an assessment

Comparability

  • Comparable: Grade and trend are comparable to the previous assessment

  • Somewhat comparable: Grade and trend are somewhat comparable to the previous assessment

  • Not comparable: Grade and trend are not comparable to the previous assessment

  • Not previously assessed
