Protecting Rubicon's built assets from fire
Rubicon is managed primarily for conservation of natural values, but slashed firebreaks along the fence lines and vegetation reduction around the house are used to protect these assets.
We have followed the guidelines of the Tasmania Fire Service which recommend, for flat land, an inner protection zone of 20 metres around the house and an outer protection zone of 15 metres.
For the inner protection zone, which is from the house out 20 metres, we remove all trees and most shrubs and we keep the understorey vegetation relatively short.
Beyond this zone there is an outer protection zone which extends to about 35 metres from the house. Some shrubs and trees are retained and understorey vegetation is slashed on a 3-5 year rotating basis. We remove bracken from this zone on an annual basis, with an aim to permanently remove the bracken. The outer edge of the outer protection zone is marked by a track that is kept closely slashed.
We maintain a reduced fuel zone about 50 metres from the house with a width of about 15 metres, where vegetation is slashed or burnt every 3-5 years. Between the outer protection zone and the reduced fuel zone, we reduce the fuel by cutting out the bracken from under the trees every 3-5 years.
Protection for the boundary fences is achieved by regular slashing immediately inside the fence and outside the fence on the roadside. We spray with "frog friendly" glyphosate immediately under the fence to avoid vegetation growing up into the fence itself.
The map of disturbance below shows the slashing to the north and west of the house in the inner protection zone, and recent slashing and burning the reduced fuel zone.
