Vegetation Management Plan - Bidjigal ReserveAssembling Flora ListsThe assembly of flora lists is basic to all bushland projects. The purpose of the bush regenerationproject is not to accumulate an ever-increasing list of new species, but rather to record the diversityand abundance of the existing vegetation community and to monitor any changes that take place asthe project proceeds.Flora lists should be updated regularly and the location(s) of any unusual, rare or threatened speciesshould be marked on the base map and the relevant authorities should be informed (eg. NationalHerbarium, DECC/NPWS).In addition to the information recorded in permanent quadrats, comprehensive lists of plant specieswill be maintained and updated for each management zone. This will be performed as perThreatened Species Survey & Assessment Guidelines NPWS.Assembling Fauna ListsThe recording of fauna follows the same guidelines as for flora and is of equal importance. In thefirst instance a simple list of fauna sighted (or evidence of) can be used.Ultimately, comprehensive (both exotic and native) fauna lists will be compiled and maintained.Data will be collected as per NPWS Wildlife Atlas Format.Assembling a List of Flowering and Fruiting TimesFor the native species, a long-term project will be useful since this project calls for local seedcollection and propagation.Adapting weed-clearing activities to coincide with natural seeding times and germination patterns ofdesirable natives is advised, as clearing weed growth increases germination sites and increasesseedling survival chances.For each indigenous plant species, the flowering and fruiting period will be recorded each year as aweek of year figure (i.e. 1 to 52). This is to monitor for pollination and seed set.Keeping a record of flowering and fruiting times for local weed species can make weed controleasier. For example, if it is known that Pampas Grass flowers and as the seed ripens locally betweenMarch and May; plan to treat Pampas Grass well before that time. If berry-fruited weeds likeCotoneaster, Lantana or Privet are present, remove the plants before the berries are ripe andattractive to birds.It is recommended that quantitative measurement be used within each management zone in orderto provide information relating to:• Type and % cover of weed species before and after bush regeneration work;• Type and % cover of native plant species before and after weed removal; and• Type and % cover of native plants species regenerating after regeneration.UBM Ecological Consultants Pty Ltd
Vegetation Management Plan - Bidjigal ReserveMonitoring Soil Seed Bank TrialsThese trials will allow the testing of a range of strategies designed to stimulate native plantregeneration.Quadrats will be monitored every three (3) months for 12 months. Results will be quantified bymeasuring % cover using Braun-Blanquet (see Moore & Chapman 1986), visual analysis andphotographs taken from a series of fixed photo-points.Threatening ProcessesAll Threatening Processes operating within the BGHF Habitat areas, including those listed as KeyThreatening Processes under the State relevant legislation (TSC Act) must be noted; and relevantdata collected.Monitoring of any Threatening Processes that occur will be consistent with the relevant ThreatAbatement Plans.PhotographsTaking photographs is an easy way to record changes in vegetation structure. A photographcaptures the subtle changes that are often missed when working closely on a site over time.Photographs are useful in recording sequence shots at various stages in the project to illustrate thetechniques used and the results obtained, and are also valuable teaching tools.Photography in the bushland environment is not particularly easy for amateurs, as plants castshadows and without the correct lens filters, everything looks ‘green’. Obtain professional adviceabout ASA ratings and take photographs early in the morning or when conditions are overcast.A number of permanent photo-points will be selected and marked with a short wooden stake. Thelocation of these photo-points will be recorded on a base map. Photographs will be taken from thesame spot every six (6) months.Other Monitoring VariablesOther useful variables recommended include:Temperatures - these can be recorded using a wet-dry bulb thermometer. Data may be graphed toshow that as the canopy re-forms (regardless of height above the ground) fluctuations oftemperature become less extreme. Changes in temperature can be related to the type and numbersof native plants regenerating.Recording sites (marked and recorded on a base map) can be selected and regular soil temperaturereadings taken with the bulb just under the soil surface (e.g. 2-4 mm) and air temperature readingstaken about two (2) metres above the ground.Light readings - these may be taken using a light meter, first at ground level, and again at a height oftwo (2) m. Relate the light intensity to the type and number of native plants regenerating and/or tothose already growing on the site.UBM Ecological Consultants Pty Ltd
