Gondwana Link

Lindesay Link

The Lindesay Link landscape stretches roughly 70 km from the Walpole Wilderness Area (Mt. Lindesay National Park) in the west to the Porongurup Range National Park in the east.  The boundary is shown in yellow on the map below.

The significance of this area 

Like much of Gondwana link’s Central Zone, the Lindesay Link area has a rich biological diversity with very high plant species richness.  There are also many wetlands with important plants and animals, particularly as the Link contains the junction of a number of catchments which flow in different directions.  This section of the link also represents the end of the range for a number of species, such as marron and the red-tailed black cockatoo.

At the top of Lindesay Link is the Porongurup National Park, the largest inland area of native vegetation between the Stirling Range and the coast, and a disjunct outlier of the wet Karri forest community– considered a relic of a climate shift from several thousand years ago.  The park, though small, has more than 700 plant species, including a number found nowhere else, and strong Noongar Aboriginal cultural values.

The western and southern part of the area has many plantation forestry properties, most containing important remnant vegetation and associated fauna.  This wetter region of the Lindesay Link landscape has more natural vegetation - primarily forest.  As we move east towards the Porongurup Range National Park,  the plantation/forestry landscape changes to mixed and broadacre farming (livestock and grain cropping) with more farmland relative to bush.
Stresses on the ecological values of this area are in part linked to changes that have come about from past agricultural clearing, such as fragmentation of bush, changes in water flows and rising salinity.  These issues are well known within the community, who are continuing to take active steps to address them.

The Story so Far 

The Wilson Inlet Catchment Committee and community members have developed a Conservation Action Plan for the Lindesay Link portion of Gondwana Link. Implementation of this plan is aiming to maintain and improve the distinctive nature of the Lindesay Link landscape and have native bush, wildlife and healthy waterways co-existing with a productive and vibrant rural and farming community.

Current projects to address CAP priorities include feral animal control with fox / cat shoots and eradication programs on private land which supports DBCA work on reserves to eradicate foxes using 1080 baits delivered by innovative pest injectors. Honey Possum surveys are underway to determine priority habitat for protection.

The Committee also have a high priority on protecting water quality across the many streams and wetland, and in the downstream estuary. 

Achievements 

  • Established a feral control program that assists landholders to engage a contractor to cheaply and efficiently kill foxes across a region in an ongoing way. 
  • Public education on a range of biodiversity issues, including weed control, water quality and impact of ferals.
  • Mapped the distribution of honey possums which indicates where priority bushland lies.
