4.2 Additions of Land to the National ParkIn future, the National Park may have parcels of land added to its area. In the first case the land willbe added to the Natural Area, Managed Natural Area or Special Area classification. Site developmentrequirements within these additions will be assessed, and, if any, then General Outdoor RecreationAreas will be established. It is expected that the Boranup State forest will be added to theLeeuwin-Naturaliste National Park during the life of this plan but due to the uncertainty of timingfew specific comments have been made about the area in this plan.5.0 LAND MANAGEMENTErosion of the land surface in the National Park is caused by natural processes (wind, water) andhuman use (e.g. vehicles, pedestrians and horses). The coastal zone is subject to constant interactionof natural processes acting on the beachface, dunes and cliffs. Most areas are inherently unstable andexhibit cyclical (diurnal or seasonal) erosion and accretion or long term erosion. Natural processesare frequently exacerbated by human activities. Prior to the declaration of the National Park manyareas were grazed. Grazing of coastal dunes promoted massive instabilities through the removal ofvegetation and erosion of large areas. With the discontinuation of grazing many of these areas havenaturally revegetated. In recent times, however, erosion in many coastal areas has been initiated byrecreation activities. Demand for access to beaches has led to many dunes and cliff faces beingcovered in a myriad of access tracks. In some cases poor drainage from adjacent recreation sites hascontributed to the problems.STRATEGYThe key to coastal management is the retention and rehabilitation of dune vegetation. This is criticalin foredune areas which act as a sediment store in periods of rapid erosion. Where dunes arevegetated defined access paths must be provided. No other developments should occur on foredunes.Areas where vegetation has been damaged should be rehabilitated. In some cases plantings of localnative species is sufficient, but in larger areas, where accretion of sediment is desirable such as onparabolic blow out dunes or transgressive sheets, the use of sand trapping fences, brushing ormulching may be required.Areas subject to heavy visitor use will be the primary object of rehabilitation programmes. Otherareas may be subject to natural erosion or from influences such as fire, but these are frequentlyself-stabilising, or present no threat to human activity or property. Sites will be prioritised to enablerehabilitation programmes to be implemented in each block of the National Park (see also Action3.13).11
GUIDELINESa) Where appropriate, local native species should be used in rehabilitation programmes. It may benecessary to use marram grass in some situations. Monitoring and maintenance of existingrehabilitation sites is essential to ascertain the success or otherwise of techniques. There may be aneed to promote the establishment of secondary colonising species when initial plantings aresuccessful.b) Fertiliser should be applied at the time of planting (generally winter months) and at the end of thefirst year.c) Design of tracks or roads should take into account the potential erosion hazard. Construction ofaccess should be accompanied with soil stabilisation measures.d) Provision of walk trails should relate to preferred visitor destination. They should be demarcatedby low profile fences. No barbed wire is to be used.e) Deflated areas may require the erection of sand trapping fences similar to those at South Point,Cowaramup. Because of accretion rates, barbed wire should not be used for fencing.f) Areas should be 'brushed' with appropriate native vegetation and tied down with wire. Preferablybrushing with seed set should be used.g) Access down cliff faces should be avoided where possible and only provided as a last resort. Lowprofile wooden structures should be built with care taken with steps and rises and alignment ofdecking for any boardwalks. Standards outlined in the CALM Recreation Manual should be followedwhere appropriate.h) Control of rabbits may be required in rehabilitation areas and these areas should be monitored.ACTIONSAction 5.1:Investigate the establishment of a small area for propagation of species used for coastal rehabilitation,with a primary aim of propagating marram grass (Ammophila arenaria). Other suitable speciesinclude Olearia axillaris, spinifex species and pigface (Carpobrotus aequilaterus). Possiblepropagation sites which require investigation are at Moses Rock, South Point and Hamelin Bay.Priority: 112
