Species Profile and Threats Database

For information to assist in referral, environmental assessment and compliance issues, refer to the Listing Advice and/or Conservation Advice and Recovery Plan. The Listing and/or Conservation Advice define the national ecological community and may include Key Diagnostic Characteristics, Condition Thresholds, Priority Research and Conservation Actions and additional considerations.
In addition, for recovery planning, mitigation and conservation information, refer to the Recovery Plan (where available) or the Conservation Advice.

EPBC Act Listing Status Listed as Endangered
Date Effective 16 Jul 2000
Listing and Conservation Advices For ecological communities listed from 2013 onwards, there is no separate listing advice. Instead, the advice from the Threatened Species Scientific Committee regarding the listing status of the ecological community and recommendation regarding a recovery plan are contained within the Conservation Advice.

Recovery Plan Decision Recovery Plan required, this species had a recovery plan in force at the time the legislation provided for the Minister to decide whether or not to have a recovery plan (19/2/2007).

Distribution Map Community Distribution Map

This map has been compiled from datasets with a range of scales and quality. Species or ecological community distributions included in this map are only indicative and not meant for local assessment. Planning or investment decisions at a local scale should seek some form of ground-truthing to confirm the existence of the species or ecological community at locations of interest. Such assessments should refer to the text of the Listing Advice, which is the legal entity protected under the EPBC Act.

For the legal definition of the ecological community please refer to the listing advice and other documents under Legal Status and Documents.

The caves that contain the root mat communities occur in limestone on gneiss granites of the Leeuwin Naturaliste Ridge. The caves occur within 20 km of the coastline on a Tamala (coastal) Limestone ridge that rises to 220 m above sea level (Jasinska 1997).

The "Aquatic Root Mat Community 1 in Caves of the Leeuwin Naturaliste Ridge" ecological community occurs at Easter Cave and the root mats are are produced by the roots of mature karri trees (Eucalyptus diversicolor).

The entrance of Easter Cave is located in Class A Reserve 8438, Sussex Location 4174, which is vested in the Augusta-Margaret River Tourist Bureau. The cave itself lies underneath the Cliff Spackman Reserve (Reserve 8438) that is part of Leeuwin Naturaliste National Park and is vested in the National Parks and Nature Conservation Authority for "Protection and Preservation of Caves and Flora and for Heath and Pleasure Resort".
