Info

Populations in need of linear marking are generally located along linear reserves (road and rail reserves) and firebreaksand are often associated with utilities such as powerlines, water pipelines and Telstra lines. In all these situations theyare vulnerable to damage or destruction by maintenance operations. Permanent, but discreet, marker pegs need to beinstalled at all Declared Rare Flora populations occurring along linear routes within CALM land. Main Roads W.A. hasdeveloped a field marking system for demarcating environmentally significant areas on road reserves. CALM uses thissystem to mark DRF and Priority Flora populations along linear routes both on CALM land and on other areas. LocalShires have been encouraged to adopt such a system.Taxa with populations on CALM and other lands most urgently in need of linear marking are:Conostylis dielsii subsp. teresConostylis micranthaEucalyptus synandra(xvi)Environmental WeedsControl of weeds in and near Rare Flora populations on CALM land should be conducted by District staff. Thefollowing taxa most urgently require weed control or eradication in some or all of their populations.Caladenia elegans ms Pterostylis sp. Northampton (S.D.Hopper 3349)Conostylis dielsii subsp. teresWurmbea tubulosaConostylis micrantha(xvii) Fire RegimesAll populations of Declared Rare Flora should be excluded from prescribed burns on CALM and other lands untilappropriate research has been carried out, and then only be burnt in accordance with specific fire regimes developed byboth research and regional staff. These taxa will also need to be protected (by construction of protective breaks or byreduction of fuels in surrounding areas) where possible from potential uncontrolled fires unless such fires fit theconditions determined for the particular fire regime developed for that taxon. Those taxa which are obligate seedersshould not be burnt on a frequency less than that required for the plants to produce adequate post-fire seed forsuccessful recruitment events and sustainable regeneration of the population. Species which are lignotuberous andresprout after fire may be reduced in their capacity for regeneration after frequent fires.Taxa considered to be at greatest risk from frequent fire or requiring protection/exclusion from fire until specific fireregimes are developed are:Beyeria lepidopetalaCaladenia bryceana subsp. cracens msConostylis dielsii subsp. teresConostylis micranthaDrakonorchis barbarella msEremophila viscidaEucalyptus blaxelliiGrevillea christineaeLeucopogon marginatus3. Priority Flora in the Geraldton DistrictThe conservation status of the Priority Flora (poorly known but thought to be rare) in the Geraldton District is assessedin Part Three. Recommended status, based on recent surveys, is listed in Table 3. For Priority taxa the most urgentrequirement is further survey to enable an accurate assessment of their conservation status. Usually Priority One andPriority Two taxa are in most need of survey because of the low numbers of populations and small population sizes.4. Implementation and Term of the Management ProgramA recovery team will be appointed which will oversee and report annually to CALM’s Corporate Executive on theimplementation of this Management Program.This Program shall run for a period of 10 years, unless subsequent research or changes to the Schedule of Declared RareFlora cause it to be superseded earlier. During this period, the Department of CALM may institute any changes to theprovisions outlined in this Program as are found, through further research, to be necessary for conservation of theDeclared Rare Flora in the District.30
