What the results tell us for Upper Lachlan

There were no significant changes recorded during the 2008-09 period. As was reported in 2004-08 seven pest animals were recorded in the Upper Lachlan Shire. 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 distributions and abundance is unavailable.

Activities of six pest animals are listed as Key Threatening Process in the Upper Lachlan Shire.

Furthermore, there are two priority actions to manage habitat and feral control for 2 threatened populations and species listed by Department of Environment and Climate Change (DECC) within the Shire.

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’.

Information detailing control programs for pest animals undertaken by Goulburn and Yass 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 Department of Primary Industries (2007) Pest Animal Survey: A review of the distribution, impacts and control of invasive animals throughout NSW and the ACT, Vertebrate Pest Research Unit, Department of Primary Industries, Orange

Seven types of introduced animals were reported to be pests in Upper Lachlan Shire during the reporting period: wild dogs and dingoes (Canis lupus familiaris, Canis lupus dingo and hybrids), foxes (Vulpes vulpes), rabbits (Oryctolagus cuniculus), pigs (Sus scrofa), feral goats (Capra hircus), wild deer (Cervus spp, Dama dama and Axis spp) and cats (Felis catus) (see Table 1). Feral cats and foxes cover the entire Upper Lachlan Shire area in medium, low and high densities. Rabbits are the second most widely spread pest animal (75%) whilst feral pigs and feral goats cover approximately 30% of the Shire.

Table 1. Pest animal species within Upper Lachlan Shire, 2008
Species Preferred Habitats Distribution and Density (High, Medium or Low*)
Dingoes and wild dogs (Canis lupus familiaris, Canis lupus dingo and hybrids) Lands affected are mainly those adjoining areas of native forests and woodlands and surrounding modified pastures Scattered low, medium and high density populations in the north-east and east of the Shire
Feral Pigs (Sus scrofa) Found wherever available cover is present, adjoining open grazing lands – within native forest and woodland Medium to low density in the northern regions of the Shire
Feral Goats (Capra hircus) Generally along major river systems and their tributaries – some areas of native forest and woodland Medium density populations in the north and scattered low density populations along the eastern boundary of the Shire
Rabbit (Oryctolagus cuniculus) Concentrations across all habitat types Low density populations predominantly in the north and along the eastern boundary of the Shire
Fox (Vulpes vulpes) Across the entire Council area in all habitat types High density populations concentrated in the north, medium density in the east and low density in the south, south west
Wild Deer (Cervus spp, Dama dama and Axis spp) Predominantly modified pasture, pine plantations and areas of scattered native forest Low density population scattered near Crookwell and north of Crookwell on the boundary
Cat (Felis catus) All habitat types Majority of Council area has a low density population with scattered medium and low pockets around the eastern and southern parts of the Shire

Information detailing the changes in density of pest animal populations was unavailable for the current reporting period.

Information on pest animals in conservation reserves within the Shire was also unavailable.

Pest animals as threatening processes

The activities of six pest animal species in NSW that are present in the Upper Lachlan 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 4).

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
Predation, habitat degradation, competition and disease transmission by feral Pigs (DECC 2008f) Final: 27 August 2004
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 two priority actions under the ‘habitat management: feral control’ recovery strategy in the Upper Lachlan Council . These actions apply to two threatened species and populations. These include; the Eastern Bentwing-Bat (Miniopterus schreibersii oceanensis), vulnerable to foxes and feral cats, and the Northern Corroboree Frog (Pseudophryne pengilleyi) under threat by various feral animals degrading habitat (DECC 2008h).

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 NSW DPI, DECC, Department of Lands (LANDS), Catchment Management Authoritys (CMA), Rural Lands Protection Board (RLPB) 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 RLPB. DECC priorities 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 detailed information on pest animal control programs in conservation reserves in the Shire was available.

Rural Lands Protection Board

No information was available detailing control activities undertaken by the Goulburn and Yass 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 Upper Lachlan 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 RLPB Districts, DECC (National Parks and Wildlife Service - now The Department of Environment and Climate Change), 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:

Table 3. Density divisions for pest animals
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.
