DESCRIPTION

Control Effectiveness of fence and no fence. The non-fence control expenditure in the Esperance region is about 70% of the Kalbarri to Lake Moore section yet it provides less than a tenth of the protection against emus and possibly less protection against wild dogs. - PowerPoint PPT Presentation

  • The non-fence control expenditure in the Esperance region is about 70% of the Kalbarri to Lake Moore section yet it provides less than a tenth of the protection against emus and possibly less protection against wild dogs.Source: Benefit-Cost Analysis of the State Barrier Fence 2007

  • What causes more economic cost, emus or wild dogs?Answer: emusHowever, research shows the impact of wild dogs cause greater concern. Farmers are strongly affected by the distress and injury that wild dogs can inflict upon their stock.Along the Esperance extension the majority of benefits are expected to arise from emu control

  • How much will the fence cost the landholderUse the following examples to calculate the cost of your levy:EG1: Farm valuation= $679000 (farm size: 1165.51ha)UV Rural rate= $3841.78Estimated interest rates: 4.4% over 10 years or 2.9% over 20 yearsTo find cost of SBF levy:Over 10 years - $3841.78 x 4.4% = $169 (in this case approx. 14.5c/hectare per year)Over 20 years - $3841.78 x 2.9% = $111.41 (in this case approx 9.5c/hectare per year)EG2: Farm Valuation= $1087000 (farm size 2226ha)UV Rural Rate= $6200.25Estimated interest rates: 4.4% over 10 years or 2.9% over 20 yearsTo find cost of SBF levy:Over 10 years - $6200.25 x 4.4% = $272.81 (in this case approx. 12.3c/hectare per year)Over 20 years - $6200.25 x 2.9% = $179.81 (in this case approx. 8.1c/hectare per year)NB: Should the amount of your UV rural rate increase, the percentage charged against it will decrease so that the levy amount remains the same each year. The levy will only alter if the value of the land, as per the Valuer General's valuation, changes. This may be an increase or a decrease.

  • Required to gauge community support for the fence extension project.$1.76m to be raised by Specified Area Rate for 10 or 20 yrs across Unimproved Value rate properties.The amount contributed by each rate assessment is determined by the valuation of each property.State & Federal Government are not willing to commit more funds unless the industry is willing to financially support the projectIf the project goes ahead Government will be putting in $4 for every $1 industry puts in.

    If the Referendum fails the project will not go ahead. This will be Esperances only chance to have the State Barrier Fence extended to protect all farming properties in the region.

  • The barrier fence will surround the Esperance farming region.Cost analysis shows a 2 to 1 return on the $ invested.The SBF is a long term and more permanent solution to dog and emu migration.Doggers work well when they are obtainable. No guarantee of availability into the future.This will be the only chance to have the fence extended.
