Environmentally Sensitive Areas as declared in Environmental Protection (Environmentally Sensitive Areas) Notice 2005, Government Gazette No. 55. This dataset is provided to assist landowners and managers in determining the location of environmentally sensitive areas under the Environmental Protection Act 1986. It is not a substitute for any requirement of the legislation. Those seeking further information should contact the data custodian. The ESA data was originally produced by Department of Water (D0W), completed at 30/05/2005. Department of Environment and Conservation (DEC) produced a new ESA data set to amend errors in the ESA data set. The custodian of the Environmentally Sensitive Areas dataset is now the Department of Water and Environmental Regulation. For further information contact Clearing Regulation Branch (08) 9333 7510. This dataset was formerly known as Clearing Regulations - Environmentally Sensitive Areas (DER-016)

Clearing Instruments Activities (areas approved to be cleared under a clearing permit) for Western Australia are derived from authorisations and other instruments relating to Clearing of Native Vegetation under the Environmental Protection Act 1986. Data is captured by the Department of Water and Environmental Regulation and other agencies under delegated authority. Data captured represents the location of land clearing where clearing may be conducted. Data is captured to the accuracy required by the request. The request can be captured directly from within the Clearing Permit System application (freeform shape) using image based maps as a background for simple requests or by importing a shape file when the request is complex.

Clearing Instruments Conditions (areas subject to conditions under a clearing permit) for Western Australia are derived from authorisations and other instruments relating to Clearing of Native Vegetation under the Environmental Protection Act 1986. Data is captured by the Department of Water and Environmental Regulation and other agencies under delegated authority. Data captured represents the land clearing areas where conditions may apply. Data is captured to the accuracy required by the request. The request can be captured directly from within the Clearing Permit System application (freeform shape) using image based maps as a background for simple requests or by importing a shape file when the request is complex.

The "Clearing Control Catchments - CAWSA" dataset relates to Country Areas Water Supply Act 1947 (CAWSA) Part IIA Control of Catchment Areas legislation for controlling the clearing of native vegetation to prevent salinisation of water resources in some existing or potential water source catchments. The dataset is used by the Department of Water and Environmental Regulation in administering clearing licence applications, policy decision making and for providing advice. The catchments depicted were proclaimed 1976-1978 and became subject to clearing controls where land owners and occupiers could not clear native vegetation on their property unless authorised under a CAWSA Licence to Clear. The "Clearing Control Catchments - CAWSA" dataset also shows Zones of salinity risk in the controlled catchments where Zone A is the highest salinity risk and Zone D the lowest. These zones were used to determine where, in the administration of clearing controls, some limited clearing may be granted in areas of lower salinity risk. Since the advent of Environmental Protection Act 1986 (EP Act) clearing regulations in 2004, native vegetation clearing proponents state-wide must obtain an EP Act Permit before undertaking any clearing. Landowners and occupiers of CAWSA compensated land and those exempt from the need for an EP Act clearing Permit are however still required to obtain a CAWSA Licence to Clear. This dataset was formerly known as CAWSA Part 2A Clearing Control Catchments (DOW-028)

The ‘Referral – Permit Application Not required’ dataset is derived from authorisations relating to the Clearing of Native Vegetation under the Environmental Protection Act 1986. Data is captured by the Department of Water and Environmental Regulation and other agencies under delegated authority. Data captured represents the location of land clearing where clearing may be conducted. Data is captured to the accuracy required by the request. The request can be captured directly from within the Clearing Permit System application (freeform shape) using image based maps as a background for simple requests or by importing a shape file when the request is complex.

Point locations of specified weeds as found in the river foreshore assessment. DISCLAIMER: While the dataset has been prepared by the Department of Water and Environmental Regulation, it contains information from State and federally funded foreshore assessment projects conducted at different times by Natural Resource Management groups with support from DWER regional offices. It should be noted that for any given location, the data provides a ‘snapshot’ of the attributes recorded at one specific time. Any information or representation expressed or implied in this database is made in good faith and on the basis that the Department of Water and Environmental Regulation and its employees are not liable for any damage or loss whatsoever which may occur as a result of action taken or not taken, as the case may be in respect of any information or representation referred to herein. Professional advice should be obtained to verify the information contained in this database before applying to particular circumstances. The Department of Water and Environmental Regulation accepts no responsibility for collecting or updating this data, some known errors are being addressed. This dataset was formerly known as Foreshore Conditions - Weeds (DOW-053)

Special Areas dataset have been developed to incorporate a number of datasets. It is to be used in-conjunction with the Zones and Reserves. It contains Bush Forever Areas, Water Catchments, Environmental Conditions and Special Control Areas.

As part of the stages of water restriction, the Department of Water and Environmental Regulation prepared a state map contained four different areas of water restrictions which are controlled by the Water Agency (Water Use) by-laws 2010. Dataset was formerly known as Sprinkler Restrictions - Water Agencies (Water Use) Bylaws (DOW-064)
