It’s easy not to fully appreciate the geography of a place, even one you’ve visited for over 40 years.
Of course, having crossed the bridge over the Painkalac Creek between Airey’s Inlet and Fairhaven hundreds of times, I had seen the transformation of the inlet and estuary from a degraded, treeless landscape to the wonderful wetland area it is today. That transformation is due to the commitment and hard work of many members of ANGAIR and the community over a long period. What I hadn’t really noticed was how, hidden from view when crossing the bridge, there was also an upper part of the Painkalac Valley, a flood plain skirted by Bambra Rd running from the bottom of the Aireys Inlet hill to the meandering edge of the Painkalac Creek.
This flood plain, despite having been cleared over a hundred years ago, still contains a series of remnant water features: ephemeral lakes, billabongs, watercourses and small tributaries to the main creek despite the limiting effect of the Painkalac Dam upstream. Around the world it is these wetland habitats, so important for birds, animals and plants, that are most under threat from human activity. The Painkalac Creek is such an important environment that it has recently been listed by the Federal Environment Minister as one of 25 ‘salt wedge’ sites around the Australia coast worthy of special protection.
Having seen the success with rehabilitating the lower valley, my wife Jacinta and I bought an area of approximately 11 acres in the upper valley on Bambra Rd near Old Coach Road. We were particularly interested in this site as it included a large, drained series of billabongs which could be seen in old aerial photographs.
The billabongs were drained and back filled several decades ago. We aimed to revegetate the block and reinstate the billabongs and ephemeral lake that still frequently form over winter and spring as seen in the drone photo, left taken after heavy rain in September 2017. The wetlands will provide not only habitat for birds and native animals but also improve the water quality of the creek.
ANGAIR has enthusiastically supported this project and successfully applied for a Victorian Landcare Grant to facilitate the rehabilitation of the block. Working bees have already started with up to 30 enthusiastic volunteers involved.
The aim is to plant local indigenous species, extending the natural vegetation on the eastern side of Bambra Road down to the Painkalac Creek, providing a natural corridor between the two. Almost 1500 plants are already in the ground as seen in the photos above and below.
Freesia refracta and Freesia alba X F. leichtlinii are declared weeds in the Surf Coast Shire because they spread easily and threaten to invade bushland. Freesias are perennial herbs that die back in summer and produce new foliage in winter. The highly fragrant trumpet-shaped flowers appearing in spring are white to cream and pink with yellow markings, shaded purple on outer surface. Each plant has at least two corms, one below the other, thus requiring deep digging to remove them.
More details about how to control this weed can be found in the archive of Weeds of the Month.
There are a number of wonderful local Friends Groups that provide ANGAIR members and the community with opportunities for involvement.
