15172: Revegetating Biodiversity Corridors and Mitigating Bushland Livestock & Bridal Creeper

    Four biodiversity zones will be targeted in the Shire of Kent, with large bushland blocks and nature reserves forming the biodiversity 'core' for these zones, from and between which revegetation corridors will be established to link these 'biodiversity hotspots'.   Eucalypt woodlands of WA's wheatbelt have been draft-listed as a threatened ecological community under the federal Environment Protection and Biodiversity Conservation Act 1999. All of the four target zones harbor these woodlands, however long term livestock grazing threaten to degrade the flora structure and composition of these threatened ecological communities, so livestock exclusion from these woodlands, via fencing, is critical for long term biodiversity conservation. Other threats include:

    • Bridal Creeper is a nationally declared weed and its invasive nature also threatens these wheatbelt woodlands, especially the understory flora, were this creeper can out compete the native species and the micro habitats they provide to the woodland floor. Physical removal of bridal creeper will prevent further spread and minimise risk associated with alternative control options, such as damage to native flora and fauna from herbicide.  
    • Risks resulting from historical land-clearing, which include rising groundwater tablets and associated dryland salinity. Unfortunately salinity at several of the targeted zones has started to degraded remnant bushland or is in the process of doing so. Revegetation works in both groundwater recharge and discharge areas will aim to prevent further spread of salinity near remnant vegetation areas.  
    • Wind erosion due to poorly managed sandy soils. Appropriate flora species for revegetation will be selected for these wind erosion sites to ensure soil conservation is maintained for the preservation of adjacent remnant vegetation.  
    • Water logging of flat land after heavy rains may also pose a risk to revegetation works, so tree planting will be planned around waterways, so that flows are not restricted by revegetation works.
    It is anticipated that volunteers will be involved with the proposed on-ground works including fencing, revegetation and physical removal of bridal creeper.
    Students from John Tonkin College will participate in planting 9000 revegetation seedlings at Biodiversity Zone One around 'East-Chinocup' (Pingrup) lakes and reserves.
