Australian governments receive yet another warning that mass extinction events are getting closer


All three tiers of Australian governments - federal, state and local - need to turn and face this reality.

Abstract 

Australia’s 2019–2020 mega-fires were exacerbated by drought, anthropogenic climate change and existing land-use management. 
Here, using a combination of remotely sensed data and species distribution models, we found these fires burnt ~97,000 km2 of vegetation across southern and eastern Australia, which is considered habitat for 832 species of native vertebrate fauna. 

Seventy taxa had a substantial proportion (>30%) of habitat impacted; 21 of these were already listed as threatened with extinction. 
To avoid further species declines, Australia must urgently reassess the extinction vulnerability of fire-impacted species and assist the recovery of populations in both burnt and unburnt areas. 

Population recovery requires multipronged strategies aimed at ameliorating current and fire-induced threats, including proactively protecting unburnt habitats. [my yellow highlighting]

The Guardian, 21 July 2020: 

The publication of the peer-reviewed study in the journal Nature Ecology and Evolution followed the Morrison government on Monday releasing an independent review of the laws, known as the Environment Protection and Conservation Biodiversity (EPBC) Act. 

The interim review led by Graeme Samuel, a former competition watchdog head, found Australia’s environment was in an unsustainable state of decline and the laws were not fit to address current and future environmental challenges. 

Samuel recommended the introduction of national environmental standards that set clear rules for conservation protection while allowing sustainable development, and the establishment of an independent environmental regulator to monitor and enforce compliance. 

The environment minister, Sussan Ley, agreed to develop environmental standards, but rejected the call for an independent regulator and said she would immediately start work on an accreditation process to devolve responsibility for most environmental approvals to the states and territories. 

One of the Nature Ecology study’s authors, Prof James Watson, said the laws could be effective but only if protections were enforced. 

The act, which has been widely criticised for failing to stem a developing extinction crisis, largely leaves decisions to the discretion of the environment minister of the day.....
