Short Range Endemics

What are they?

Short-range Endemics (SREs) are species – mostly invertebrate – with ranges smaller than 10,000 km². The current distribution of SREs in Western Australia is a result of biology as well as geographical history, with the origins of many SREs dating back as long ago as the Gondwana supercontinent (approx 180-65 million years ago).

SREs are found in areas of higher moisture levels including microhabitats associated with the shady southern slopes of hills and ranges, rocky outcrops, deep litter beds, or combinations of them.

Conservation issues

The biology of most Short-range Endemics is largely unknown and their precise distribution and life history are poorly documented.

Because of their ancient origins, small size and often specialized behaviour, SREs habitats are extremely vulnerable to disturbances like clearing, surface pollution and direct removal of material (excavation).

These activities can directly cause or indirectly contribute to extinctions, so identifying the conservation value of SRE species has become an essential part of Environmental Impact Assessments and project approvals.

Capabilities

At Ecologia Environment, our team of industry-leading invertebrate zoologists specialise in the survey, identification and management of SREs in WA. Our team of SRE specialists are well regarded in this field; maintaining well established relationships with regulators and members of academia.

Using a rigorous risk based approach, our team is able to advise you on the need for SRE surveys in your project area, and conduct the surveys if required. If SREs are present, we are able to develop and implement monitoring and management plans for you, or provide you advice in this regard.

Throughout this process, we will consult with appropriate regulators to ensure that there are ‘no surprises’ during project approvals.
