Granite coastline Albany region

Granite coastline Albany region south west Western Australia comprise of cliffs and boulders, impressive both in scale and in their protracted war they wage against a restless, pounding, Southern Ocean. The windswept coastal heath above these rocky shores consists of highly specialised plants, adapted to survive in harsh conditions. Salt residue from sea spray coats their leaves, their root systems barely grasp these slopes made tenuous by shallow soil, and the lack of protective soil contributes to the plant’s thermal and water stress. The harshness of the conditions is often masked by the heath’s varied display of plants and wildflowers, set against the grandeur of a rugged and isolated coastline. This isolation and ruggedness combined with other recreational pursuits draw people to the coast. But we are in danger of loving it to death.

4WD track erosionFour wheel drive tracks along sensitive areas of coastline are increasing in number and severity of their condition. Frequent use of tracks by vehicles quickly leads to erosion, which is further aided by water run off, cutting deep channels along the wheel paths and making them unusable in parts. The drivers’ solution is to create new tracks around difficult sections, thereby creating an ever widening excoriation of the coastal heath, leading to further damage to the plants that stabilise the top soil.

The worst examples of damaging 4WD are actually rather short in distance, usually radiating from a more established track directly down the heath slopes before stopping just above the cliff lines. For the short 30 or 40 metres of vehicular travel they “provide” they become large visible scars cutting directly down the slopes. Erosion from rainfall is at its maximum potential with orientation of these “tracks”.  The remoteness of many of these locations means this damage is often proceeding unchecked, out of sight and out of mind. The 4 Wheel Drive Clubs in WA and Department of Parks and Wildlife need to get together to discuss and action a plan to minimise this type damage in National Parks. Or maybe we will leave things as they are to continue, then ask Lotteries West for funding and a bunch of volunteers to eventually carry out some type of “vegetation rehabilitation” on our scarred coastline? Prevention would seem a better option all round.
