The Perth Hills Location
Typically, ‘Perth Hills’ is a phrase that is used for advertising purposes, to refer to the area of Darling Scarp that is situated in the Mundaring Shire and Kalamunda City. This territory is governed by the East Metropolitan Regional Council (EMRC).
The phrase is normally used in tourist guides, and in pamphlets produced by the government’s Environment Department. This department is based in Mundaring Weir, at the Perth Hills Centre for National Parks. It promotes its’ ‘Nearer to Nature’ program and related activities. This phrase has appeared in numerous books as well.
The Regions of the Perth Hills
Darlington and Kalamunda, as two distinct locations, were often classed as ‘The Hills’ because of their location on the Scarp’s edge, and the steep roadways present in those areas. Frequently, Greenmount Hill is regarded as the Hills’ ‘entrance’, because the Great East Highway (which is the main road) travels through this region, next to the route where the previous York Road passed.
The Swan Hills
These hills are in the Toodyay Road area, which encompasses the city’s northeastern regions of Gidgegannup and Swan. The phrase ‘Swan Hills’ has been used for other purposes too.
The Mundaring Hills
The Perth Hills welcome sign in Greenmount Hill, 100 metres from Chippers Leap, is the entrance to that area of the Mundaring shire hills.
The Kalamunda Hills
Another Perth Hills welcome sign is positioned on Kalamunda Road, ahead of the road to Kalamunda. In addition, the area includes the Carmel Wine and Bickley region.
The Armadale Hills
There are hills and localities over Armadale, which are distinct from the hills’ other localities.
In the previous usage of the phrase ‘The Hills’ by Perth residents, the identification of certain areas of Darling Scarp saw some landmarks more commonly mentioned than others.
The Location of Fire Breaks in the Perth Hills
Firebreaks should be positioned so that they occupy the majority of the preferred outcomes. As with every situation, there has to be a balance between the perfect firebreak location, fencing needs, soil conservation, cost and practicality.
Therefore, the firebreak should be positioned so that it either stops lower intensity fires, provides a back burn buffer from where the burning can be undertaken or offers access to vital infrastructure or other valuable areas.
Fires in the bush travel quicker uphill than downhill. Therefore, it is better to position firebreaks lower down and, whenever possible, arrange them so that they run parallel with the contour. If the firebreak crosses the contour, the probability of erosion is greater and steps must be taken to reduce the erosion danger.
The location of Firebreaks should accomplish four aims:
1. Offer lower fuel zones or mineral earth breaks, so that unexpected fires cannot enter properties – i.e. an external threat safeguard break.
2. Offer lower fuel zones or mineral earth fire breaks, so that unexpected fires can not spread elsewhere – i.e. an internal threat safeguard.
3. Ensure that prescribed burns cannot leave the designated area for burns – i.e. a specified burn boundary.
4. Offer access to vital land areas, so that measures to suppress fires can be implemented – i.e. an allocated back burning border.
