Type of offset management plan

Check the box to show which type of offset management plan you are completing

☒Revegetation only (do not complete section 5 or 6)

☐Protecting existing trees and revegetation

Section 1: Principle and goals

  1. Offset requirements

3 small trees and 1 large old tree of low conservation significance are being removed
A total of 100 revegetation plants are required
  1. Objectives and goals

To increase the cover of indigenous plants on the property.
To help stabilise the soil from erosion.
To create biolinks and habitat for native fauna
  1. Site assessment

The offset zones are close to an existing patch of native vegetation so this will increase the native vegetation patch size.
The area links up scattered trees to the existing patch of native vegetation.
The offset area is away from the house so that bushfire risk is not increased.
  1. Indigenous plant origin – which nursery will your plants be sourced from?

Jo Bloggs Indigenous Plant Nursery during 2018 Autumn
  1. Planting design and method (select all that apply)

Which of the following considerations have been incorporated into your plan?

☒Mixture of indigenous plants (trees, shrubs, grasses)

☒Setback of planting from built structures

☒Arrangement of plants

☒Smaller ‘square tube’ size

☒Density of the planting

☒Calculation of planting number, including replacement planting

☒Planting time

☒Tree guards, mulch and environmental threats

☒Water-holding products

☒Follow-up maintenance activities

☒Monitoring reports

☒Scheduled for a 10-year period

  1. Other sustainable land management activities

I am putting up nesting boxes for local animals. I have installed a bird bath.
I keep my cat in an enclosed cat run. I have fenced off the remaining Emerald Star Bushes.

  • Fallen timber from the protected trees will be retained and must not be harvested, i.e. not used as firewood.
  • Environmental weeds as detailed in the Cardinia Shire Planning Scheme will be controlled to the satisfaction of the responsible authority within an area twice the size of the canopy diameter of the protected trees.

Section 7: site plan

Attach a site plan to clearly show information required for the application. For a check list of requirements please refer to How to complete an offset management (OM1) plan, to ensure that you have included all the requirements.
