What the results tell us for Young
Five types of pest animals were recorded in Young Shire during the current reporting period. Due to limitations in the current reporting period data, quantitative information to assess change in the pest animal distributions and abundance is unavailable.
Activities of five pest animals are listed as Key Threatening Processes in the Young Shire. There are no priority actions for feral animal management listed by the NSW Department of Environment and Climate Change (DECC) for the Shire area.
The DECC undertook control programs within the Shire for pest animals however specific details on this work were unavailable for the current reporting period. DECC also have implemented an eight year plan for pest animal management, known as the ‘NSW Invasive Species Plan 2008-2015’ (DPI 2008).
Information detailing control programs for pest animals undertaken by Young Rural Lands Protection Board are unavailable for the current reporting period.
Pest animal infestations
The more mobile pest animal species utilise a wide variety of habitat types within all land tenures. Populations of all pest animal species fluctuate with climate, seasonal conditions and the availability of local resources. Managing pest animals and their impacts is the shared responsibility of all land managers.
The Department of Primary Industries (DPI) has undertaken a spatial survey of pest animal distribution and abundance across NSW and the ACT (see About the data for more information). See DPI (2007) Pest Animal Survey: A review of the distribution, impacts and control of invasive animals throughout NSW and the ACT, Vertebrate Pest Research Unit, DPI, Orange
Five types of introduced animals were reported to be pests in Young during the reporting period: foxes (Vulpes vulpes), rabbits (Oryctolagus cuniculus), feral goats (Capra hircus), wild deer (Cervus spp, Dama dama and Axis spp), and cats (Felis catus) (see Table 1). Foxes are the most widespread animal, covering 100% of the Shire in high concentrations. Rabbits were also present in scattered low densities, whilst goats and deer continue to populate the outer fringes in the north east of the Shire in low densities. Cats were also present across scattered regions of the Shire in medium to low density populations. Cats were reported in the previous reporting period however their density and distribution was not.
| Species | Preferred Habitats | Distribution and Density (High, Medium or Low*) |
|---|---|---|
| Feral Goats (Capra hircus) | Rough terrain on timbered country including native forests, woodlands, heath and shrubs and surrounding modified pastures, riparian areas | Low density population in the north east of the Shire |
| Rabbit (Oryctolagus cuniculus) | Concentrations across all habitat types but prefer areas of native and modified grasslands | Scattered low density populations, mainly in the east of the Shire |
| Fox (Vulpes vulpes) | Across the entire Council area in all habitat types | High density populations |
| Wild Deer (Cervus spp, Dama dama and Axis spp) | Predominantly heavily timbered areas and surrounding country also modified pasture and areas of scattered native forest | Low population pocket in the east of the Shire |
| Cat (Felis catus) | All habitat types | Scattered medium to low density populations across the Shire district |

Information detailing the changes in density of pest animal populations was unavailable for the current reporting period.
Pest animals as threatening processes
The activities of five pest animal species in NSW that are present in the Young Shire have been listed as key threatening processes in the state by the NSW Scientific Committee under the Threatened Species and Conservation Act 1995 (see Table 3).
| Name of Threatening Process | Date of Determination |
|---|---|
| Competition and grazing by the feral European rabbit (DECC 2008d) | Final: 10 May 2001 |
| Herbivory and environmental degradation caused by feral deer (DECC 2008e) | Final: 17 December 2004 |
| Predation by feral cats (DECC 2008c) | Final: 24 March 2000 |
| Predation by the European Red Fox (DECC 2008b) | Final: 20 March 1998 |
| Competition and habitat degradation by Feral Goats (DECC 2008g) | Final: 12 November 2004 |

A threat abatement plan, prepared during the last reporting period for the European Red Fox, continues to run. The plan provides a collaborative strategy for fox control programs, with the primary purpose of conserving native species in NSW (DECC 2001). Updates on this plan are currently unavailable.
There are no recovery strategy plans for threatened species, communities and populations in the Young Shire for damage incurred by pest animals.
Pest animal control activities
NSW Government agencies
The NSW DPI introduced the ‘NSW Invasive Species Plan 2008 - 2015’ which aims to protect the environment, economy and community from the adverse impacts of invasive species (DPI 2008). This eight year plan has set out a framework for the coordinated and cooperative management of invasive species aiming to prevent new incursions, contain existing populations and adaptively manage widespread species. This plan is working jointly with DPI, DECC, Department of Lands (LANDS), Catachment Management Authorities (CMA), Rural Land Protection Boards (RLPB) and stakeholders.
During the reporting period, the NSW DECC undertook control programs for pest animals in conservation areas, often in conjunction with other government agencies and/ or the RLPB. DECC prioritises on areas where new outbreaks occur, where threatened native plants or animals are at risk from the impact of pest animals, and where there is a need to minimize the impacts of pests on neighboring lands, such as farms (DECC 2008a). Detailed information on these projects is unavailable for the current reporting period.
The Invasive Animals Cooperative Research Centre (IACRC) is working on several projects aimed at controlling pest animal numbers of pigs, foxes, cats and rabbits. For example; A new bait for canids and felids which is considered fast acting, with no visible signs of distress as animals are rendered unconscious rapidly is being developed (IACRC, 2008). In addition the CRC are also developing an antidote that may be given to any domestic dogs that take baits accidentally.
No information was available detailing control activities undertaken by the Young Shire for this reporting period.
No information was available regarding expenditure and effectiveness of pest animal control within Young Local Shire for the current reporting period.
About the data
The DPI pest animal survey represents the distribution, abundance, control and impacts of major pest animals across NSW and the ACT during 2004 to 2006. Information was captured through a two-part survey involving land management agencies. Based on a density ranking system (see table below), the resulting maps depict variation in animal abundance and density across all land tenures. Information was collected on a regional scale using a grid cell basis (5x5 km – equating 25km²). Pest animal density data was obtained from pest animal managers and key representatives from Government and non-Government agencies responsible for the control of pest animals across NSW and ACT. These agencies include the RLPB Districts, DECC (National Parks and Wildlife Service - now The DECC, DPI (State Forests of NSW), Environment ACT, and Game Council of NSW.
This is a very coarse dataset and consequently the results are lacking in specific, quantitative detail compared with the previous reporting period.
Density divisions are detailed in Table 3 below:
| Density | Definition |
|---|---|
| High | Many animals seen at any time and much sign of activity i.e animals always observed, reliable sightings or otherwise evidence of high abundance. Best described as observing significant evidence of many animals on greater than 80% of occasions |
| Medium | Some animals seen at almost any time and/or much active sign i.e frequent but unreliable sightings of animals. Best described as observing significant evidence of some animals on 50–80% of occasions |
| Low | Few or no sightings and/or little active sign i.e rare sightings/ evidence. Best describe as observing very little evidence of animals 1-50% of occasions. |
| Absent | No animals i.e very unusual to see evidence of animals. Best described as seeing either no evidence or very little evidence of extremely low numbers of animals on less than 1% of occasions |
