Declared Rare and Poorly Known Flora in the Geraldton District

disease. Recreation should be controlled or excluded from sensitive sites depending on the degree of threat. Provisionof fencing may be necessary.The following taxa need to be monitored to ensure that they will not need protection from some aspect of recreationaldamage:Caladenia wanosaDrakaea concolor(ix)Habitat DegradationThere are a number of threats that may cause habitat degradation to populations of Declared Rare Flora both onconservation reserves and on other lands. Water erosion can be caused by activities at some distance from a population.The digging and trampling of feral pigs can also cause much damage. Other causes of habitat degradation are the rise inwater table and salinity.Taxa which appear to be at risk due to habitat degradation in these categories are:Caladenia elegans msEremophila niveaCaladenia wanosa Pterostylis sp. Northampton (S.D.Hopper 3349)Drakaea concolor ms(x)Ex situ Germ-Plasm CollectionsCollection and long term storage of germ-plasm (seed or tissues) from wild populations of Declared Rare Flora providesa source of propagation material for future re-establishment, in addition to ensuring protection of populations, or moreimportantly, taxa, from extinction. Collection should be carried out according to the protocols provided by theThreatened Flora Seed Centre at the Western Australian Herbarium.Priority for collection of this material will depend upon the degree of threat to the taxon. The majority of species in theDistrict are not represented in ex situ germ-plasm collections.Those taxa which are represented by few populations and/or low individual numbers are of highest priority:Beyeria lepidopetalaDarwinia masoniiDrummondita ericoidesEremophila viscidaEucalyptus crucis subsp. praecipuaGlyceria drummondiiGrevillea christineaeHalosarcia bulbosaHypocalymma longifoliumLeucopogon marginatusMenkea draboides(xi)Re-introductionTaxa poorly represented on conservation reserves may need to be considered for re-establishment in suitable, lessvulnerable habitats on land designated for nature conservation.Taxa most urgently requiring re-establishment into the wild by CALM staff under approved Wildlife ManagementPrograms or Interim Management Guidelines as outlined in CALM Policy Statement No. 29 are:Darwinia masoniiEremophila niveaEucalyptus cupreaGlyceria drummondiiHalosarcia bulbosaVerticordia spicata subsp. squamosa(xii)LiaisonMany Declared Rare Flora populations occur on or adjacent to land not managed by CALM. This requires closeassociation and cooperation with private landowners, local authorities, land managers and government agencies (e.g.Western Power, Westrail and Main Roads W.A.) to ensure their continued survival. Departmental staff are required toprovide advice and assistance, regarding conservation and management, to landholders and other agencies withDeclared Rare Flora populations on land under their control. Landowners are requested to arrange their operations sothat the area will not be destroyed or damaged in any way.28
