The Department of Conservation and Land Management (CALM) was a department of the Government of Western Australia that was responsible for implementing the state's conservation and environment legislation and regulations. It was created by the Conservation and Land Management Act 1984, also known as the CALM Act,  which is still in force as of 2020 [update]. 
The Department of Conservation and Land Management was responsible from 22 March 1985 to 30 June 2006 for protecting and conserving the State of Western Australia’s environment; this included managing the state's national parks, marine parks, conservation parks, state forests, timber reserves and nature reserves.
The Conservation Commission of Western Australia, responsible for assessing and auditing the performance of the department, was also created by the CALM Act.  Now (as of 2020 [update] renamed the Conservation and Parks Commission),  its functions have broadened, with its purpose stated as "to act as an independent and trusted community steward and government advisor for the protection of Western Australia’s biodiversity and conservation estate while fostering its appreciation and sustainable use".
