The plan is intended to be used as both a community resource and to assist Project Officers in planning and implementing the conservation and restoration of biodiversity within the East Otway Landcare area.

Some examples of benefits to rural landholders from biodiversity Biodiversity (or biological diversity) refers to the variety of life forms; the conservation practices are outlined below: different plants, animals and microorganisms, the genes they contain, and the ecosystems they form. For the purposes of this plan, we are referring to the MANAGEMENT PRACTICES BENEFITS TO LANDHOLDERS local native biodiversity of the Linton-Pittong area. Retention of remnant vegetation Habitat for birds, mammals and insects (potential reduction in insecticide use). Why is native biodiversity important? Increased shelter for stock, pasture and crops (resulting in increased production). Biodiversity affects us all and is a fundamental part of our lives and of all Potential for family recreational opportunities (bird watching, nature walks, agricultural production. Local ecosystems provide services, such as clean air etc). and water, on which we all depend and which are vital to agriculture. Many Increased property values. interactions, such as pollination, would not be possible without the presence of Conservation and protection of rare species. Legacy for future generations. other species and processes. Increased gross value of pasture output (at its highest when proportion of remnants is 34%). Natural regeneration of indigenous species. Seed supply for on-farm revegetation. Less reliance on introduced pollinators (as much as 50% of pollination is carried out by native insects that fly from nearby bushland). Reduced salinity, waterlogging, wind and water erosion problems. Improved property landscape and aesthetics. Retention or establishment of vegetation Increase in wildlife species. Waterfowl eat the snail that hosts the liver fluke parasite around farm dams and wetlands in sheep. Safer working conditions. Decreased stock fatalities. Bank stabilisation. Interception & use of nutrients before entering storage. Natural filtration provides cleaner water for stock and homestead. Maintenance of native grasses Fire protection (green fuel in summer). Feed source (selective grazing) in summer. Low rates of fertilizer required. Reduced micron size for wool Wetlands established Fire protection (firebreak and water source). Drought back-up. Family swimming area. Habitat created (with resultant natural pest control). 5 Goals for Biodiversity The principles and objectives outlined in the National Strategy for the Conservation of Australia‟s Biodiversity (1996) and further refined in the statewide strategy Victoria‟s Biodiversity (1997) provide the framework for biodiversity conservation at a National and State level, and establish “bioregions” as the basic regions for biodiversity planning. Briefly, the statewide goals for biodiversity management are to: Reverse the decline in the extent and quality of native vegetation Maintain and improve the diversity and long-term viability of species and ecological communities Maintain and restore ecological processes in terrestrial, marine and freshwater environments The Biodiversity Action Planning Strategic Overviews for the Otway Ranges and Otway Plain bioregions detail the priority biodiversity assets within these bioregions, and translate the principles into actions that will assist in achieving the statewide objectives. The East Oway Landcare Group Biodiversity Plan acknowledges the guiding principles and core objectives of the national, state and bioregional strategies. The plan outlines at a local level the priorities and actions necessary to conserve and enhance natural habitats and improve the long-term viability of the populations of native plants and animals within them.

This approach involves prioritising to conserve threatened and declining species.

The area lies within the IN E ROA H D S R Barwon Catchment, and is drained northwards by the Deans Marsh Creek, A M S D N Pennyroyal Creek, Yan Yan Gurt Creek, Retreat Creek and other minor A D A O E A R D O - P tributaries. R A E M K S A E L W E E S The landscape in the north-western section of the area consists of undulating R H Y C C # N D T D I D D L E O A W A plains and hillslopes, while the south-eastern half is characterised by deeply A BAMBRA N O P L S T D R R RIF LE BU T D T T Y E S R OA S D E dissected hills. The soils of the area are highly prone to erosion. A N D R L A O O R E L R A A G L D K T R L I R Thirty-six per cent of the study area is public land. Extensive areas in the E A A L M P T P H U P A southern half of the zone are included in the Otway State Forest, and are R A O D R O N S K R I E A D T J E R utilised for timber harvesting (mainly sawlogs for building materials) and E D R B R AT IRR E S V GU RR O A A-DEA L N S R F L M ARS EY H R D O recreation. Commercial sawlog harvesting is to be phased out of the Otway # RO A A B B D D D A A M M A DEANS MARSH B B R O State Forest by 2008. The future status of this land, including potential R A- R D A B O A C O H D E N O A A A M H R E R N additions to the reserve system, is currently being formulated by the O T O O Y E A R R D O E Y L B S R L O Victorian Environmental Assessment Council. H A A S V D M R U L A # E A R N B K N I Y TR BOONAH C K There are a number of parks and reserves in the area, most notably the O A S C R K SP Y UR N T Bambra Education Area and Bambra Bushland Reserve.

Emerging enterprises in the area include Tasmanian Blue Gum - S C W L A Y R K M plantations, olive groves and viticulture.
