What the results tell us for Harden
Five pest animals were recorded in the Harden Shire during the current reporting period. This is a similar trend to the previous reporting period however, due to limitations in the current reporting period data, quantitative information to assess change in the pest animal distribution and abundance is unavailable.
Activities of four pest animals are listed as Key Threatening Process in the Harden Shire.
Furthermore, there is one priority action to manage habitat and feral control for one threatened species listed by New South Wales (NSW) Department of Environment and Climate Change (DECC) within the Shire.
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’.
Information detailing control programs undertaken by the 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 Australian Capital Territory (ACT) (see About the data for more information) (DPI 2007).
Five species of animal were reported as pests in the Harden Shire during the reporting period: feral cats (Felis catus), feral pigs (Sus scrofa), foxes (Vulpes vulpes), rabbits (Oryctolagus cuniculus), and wild dogs (Canis lupus familiaris, Canis lupus dingo and hybrids). Cats were not reported during the previous reporting period and they now cover a significant area of the Shire in low densities. This is a significant shift in this pest animal’s distribution. The pest animal location and abundance is summarised in Table 1.
Foxes are the most widespread pest animal in the Harden Shire whilst cats are rabbits are the second most abundant pest animals.
| Species | Preferred Habitats | Distribution and Density (High, Medium or Low*) |
|---|---|---|
| Feral Pigs (Sus scrofa) |
South east corner of Shire on area of scattered native woodland and forest and native and modified pastures | Very Low density pocket south east of Shire |
| Dingoes and wild dogs (Canis lupus familiaris, Canis lupus dingo and hybrids) | South east corner of Shire on area of scattered native woodland and forest and native and modified pastures | Low density pocket in south east of Shire |
| Fox (Vulpes vulpes) |
Foxes are located across the entire Shire area. | High density throughout entire Shire region with a medium to low density pocket in the east |
| Rabbit (Oryctolagus cuniculus) |
Patchy low distributions | Scattered low distributions around the Shire |
| Cat (Felis catus) | Entire Shire district across all habitat types | Low densities throughout the Shire with scattered pockets of high density concentrations around Goulburn, east of Goulburn and the south west of the Shire area |

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 Harden Shire have been listed as key threatening processes in the state by the NSW Scientific Committee under the Threatened Species and Conservation Act 1995.
| Name of Threatening Process | Date of Determination |
|---|---|
| Competition and grazing by the feral European rabbit (DECC 2008 d) | Final: 10 May 2001 |
| Herbivory and environmental degradation caused by feral deer (DECC 2008 e) | Final: 17 December 2004 |
| Predation by feral cats (DECC 2008 c) | Final: 24 March 2000 |
| Predation by the European Red Fox (DECC 2008 b) | Final: 20 March 1998 |
Source:DECC 2008
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 is one priority action under the ‘habitat management: feral control’ recovery strategy in the Harden Shire. This applies to one threatened species, the Eastern Bentwing-bat (Miniopterus schreibersii oceanensis), which is under threat from predation by foxes and feral cats (DECC 2008h).
Pest animal control activities
NSW Government agencies
The 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 NSW DPI, DECC, Department of Lands (LANDS), Catchment Management Authorities (CMAs), Rural Land Protection Boards (RLPBs) and stakeholders.
During the reporting period, DECC undertook control programs for pest animals in conservation areas, often in conjunction with other government agencies and/ or the Rural Lands Protection Board. DECC prioritises 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 (IA CRC) 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 (CRC, 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 Rural Lands Protection Board for this reporting period.
Expenditure on and effectiveness of pest animal control
No information was available regarding expenditure and effectiveness of pest animal control within Harden Shire for the current reporting period.
About the data
The NSW 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 Rural Lands Protection Board Districts, NSW Department of Environment and Conservation (National Parks and Wildlife Service - now DECC), NSW 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 |
