1) Family name: Maluriidae
2) Scientific name: Amytornis textilis
3) English name: Thick-billed Grasswren
4) Subspecies survival status: Endangered
5) Former distribution: Arid and semi-arid southern Western Australia from the eastern Nullarbor Plain to Dirk Hartog Island
6) Current distribution: Northern half of Peron Peninsula and between Woodleigh, Overlander and Hamelin Pool.  Possibly also survives on Dirk Hartog Island.  More easterly records require confirmation.
7) Habitat: Open shrub land containing chenopods and other recumbent shrubs of 1 - 3 meters high
8) Reasons for decline: Not known.  Grazing by stock (speculative) and predation by feral cats have been suggested as reasons for the contraction of range.  Both livestock grazing and cats occur within its existing range which suggests other factors my have been affecting its abundance.  Cats, however, in association with fluctuating populations of house mice, may have caused its extinction, though this extinction has not been confirmed.  Grazing may only be a threat at high stocking rates and/or during times of drought.  But reasons for species’ decline are still not understood, in particular the relationship between grasswren abundance, grazing regime and soil fertility needs to be established.
9) Conservation reserves on which subspecies occurs: Peron Peninsula National Park.
10) Public land on which subspecies occurs: None
11) Other land on which subspecies occurs: Woodleigh, Overlander and Peron Stations.
12) Recovery plan objectives: a) To ensure persistence of the subspecies within its current range.  b) To enable re-establishment of the subspecies in conservation reserves within its former range.
13) Actions already initiated: The subspecies was studied near Shark Bay by CSIRO Division of Wildlife and Ecology in the 1980s.
14) Actions required: a) Study in detail effects of grazing regime on grasswrens and their habitat including effects on soil fertility, food availability and long term habitat processes.  The study would have to include both occupied and previously occupied sites. b) Study predation rate and productivity.  c) Prepare management guidelines.  d) Assess areas within the subspecies’ former range for translocation.  e) When suitable sites are located, translocate small numbers from the Peron Peninsula.  f) Monitor existing and new populations as frequently as possible to determine whether more urgent conservation action is required.
15) Organizations responsible for conservation os subspecies: Western Australian Department of Conservation and Land Management.
16) Other organizations and individuals involved: CSIRO Division of Wildlife and Ecology / Mike Brooker.
17) Can the recovery plan be carried out with existing resources?  No
