Flinders University Land Management Plan Flinders University 2004 - 2050 South Australia Table 5 – Management Actions for Entire Study Area Management Actions Timing Partners Biodiversity Eradicate all proclaimed pest plants and environmental weeds from areas of highest biodiversity value and control over remainder of site in short-medium term, with long term goal of eradication. Encourage natural regeneration through minimal disturbance weed control and, where necessary, undertake revegetation utilising indigenous species (refer to the list provided in Appendix A). Participate in pest animal control programs in conjunction with adjoining landholders Fire Prevention and Management Maintain fuel reduction zones along all site boundaries and any other areas requiring fuel reduction Slash grasses to reduce fuel loads – modify timing where native grasses exist Access Maintain existing trails at a condition suitable for vehicle access Ongoing Ongoing As needed Winter - Early Spring Spring - Ongoing - PCWMB UFP MC UFP NPWSA MC Design and construct new access trails with average gradients of less than 10 percent and drainage design plans As needed ORS PCWMB Recreation Continue to facilitate public use of access trails Ongoing ORS Monitor condition of mountain bike trail for two years and decide whether to permit further trail development Ongoing AMBC Provide interpretative signage to educate visitors about site features, biodiversity value, trail network and opportunities to assist in site programs - Ilkari PCWMB UFP - Catchment Management Undertake water quality monitoring in both creek systems and report to Catchment Board. Ensure staff and other site workers have training in herbicide and chemical handling, through “Chemical Users Project” 4 Management Provide adequate funding to enable priority management actions to be undertaken Undertake monitoring of actions implemented through LMP, and maintain records for future reference (detailed in Section 7.2) Actively involve School of Population, Geography and Environmental Management to incorporate site work as practical component of coursework. Seek involvement of external agencies and organisations in implementation of management actions Review the success of actions against stated objectives within each precinct, with intent of setting priorities for the 2011-2015 period.

Flinders University Land Management Plan Flinders University 2004 - 2050 South Australia 6.1.1 Precinct One – Aleppo The Aleppo Precinct extends from University Drive in the west to the Native Flora Precinct in the east. The precinct is divided by a deep valley from east to west, which contains a seasonal creek fed by the suburban catchment of Bellevue Heights. Annual testing generally indicates a high water quality, which has been steadily improving. This improvement is likely due to specific works undertaken in recent years to slow water flow and improve instream conditions, such as the gabion structures and planting of aquatic macrophytes 9 . There has been a corresponding improvement in biodiversity, with a noticeable increase in frogs 10 . Aleppo Pines are the predominant vegetation, with some scattered Eucalyptus microcarpa at the eastern end. The pines have formed a dense canopy, whilst the fallen needles prevent any understorey growth. As the pines are over 40 years old, they will continue to decline in health, and pose a threat to safety. Therefore the removal of the pines will be necessary to ensure visitor safety is not unduly compromised. The pine cones provide a valuable food source for cockatoos, therefore removal of the pines should be undertaken over a long timeframe (25 years is advocated) so that replacement plantings can gradually provide an alternate food source. Furthermore, revegetation should include a higher proportion of Allocasuarinas and Hakeas than would be typically found in the indigenous Woodland vegetation association, to ensure an adequate food source for the cockatoos. A long-term revegetation program will also minimise the visual impact and potential for severe erosion that could result if wholesale clearing were to occur. It is recommended to commence removal on the northern slope and work from east to west, to allow maximum sunlight to the creek and reduce the distribution of seed to the east. Objectives • To gradually replace the Aleppo Pine forest with an indigenous woodland ecosystem, similar to that which would have existed prior to European settlement; • To enhance the riparian environment through weed removal and revegetation; • To minimise the erosion caused by stormwater disposal and informal trails, and • To provide opportunities for informal and organised recreation. Proclaimed pest plants and environmental weeds Woody weeds – Aleppo Pines, Olives 9 Macrophytes include rushes, sedges, and reeds 10 Pers comm. Steve Hoare, FUSA Maintenance Team Leader 11 Size of proposed parcels shown on accompanying Action Plan are gauged on an estimate of 50 trees, may vary according to site conditions. Contractor quotes for 1-10 trees at $800-$1000 per tree, including the removal of tree from site (mulching tree on site will cost more). Cost per tree will decrease with increased number of trees (up to 50%). Recommendation is to budget $18,000 per annum and tender for services.
