Population control and adaptation to trapping in Indian mynas, Acridotheres tristis: mechanisms and recommendations

Lead researcher: Andrea Griffin, School of Psychology, University of Newcastle,  Andrea.Griffin@newcastle.edu.au

This project aims to examine whether intensive trapping is correlated with behavioural shifts in mynas by determining to what extent mynas from highly trapped areas differ in behaviour from mynas that range in areas that have undergone low levels of trapping. In collaboration with the Canberra Indian Myna Action Group (CIMAG), this part of the project will be conducted in Canberra, where myna trapping has been practiced for many years, so an existing array of trapped and non-trapped localities can be compared.

Second, we will identify the mechanisms of behavioural change by determining whether trapping preferentially removes bold individuals and whether trap avoidance is culturally transmitted within and across generations. This part of the project will be conducted in the Wyong Shire and will be assisted by extensive community involvement.

This project was funded under the Australian Pest Animal Research Program (APARP).

FeralScan: web-based community reporting, education and extension tool for landholders and community

Lead researcher: Peter West, NSW Department of Primary Industries, peter.west@dpi.nsw.gov.au

Many current government databases lack detailed community information. This project builds capacity among communities to record data and information for local- scale management, as well as contributes information to complement landscape level knowledge value-adding to current initiatives to report on pest species and their impacts at regional, state and national scales.

This project established a community web-based reporting (and two-way communication tool) specifically for landholders, community groups, schools, indigenous groups and non-government agencies for recording information on a range of pest animals and their impacts throughout Australia. This is coupled with a broad range of education and extension material to support best-practice pest animal management.

National mapping of the abundance of established, new and emerging pest animals to improve decision-making and the assessment of government investment programs: Part 2 – PEST BIRDS

Lead researcher: Peter West, NSW Department of Primary Industries, peter.west@dpi.nsw.gov.au

Base-line information on the extent and abundance of pest birds is required to evaluate the effectiveness of on-ground control activities, as well as government policy, programs, and investment. Current information on pest birds is primarily managed in discrete state-based datasets within many organisations, meaning that any attempt at examining trends across the Australian landscape requires collation of data from a variety of sources.

This project aimed to directly address the need for improved information on the extent and abundance of pest bird species across the Australian states and territories through 4 objectives:

  1. Implement nationally endorsed monitoring protocols (at a finer-scale) to collect, collate and report information for priority pest bird species throughout Australia (to complement existing datasets for terrestrial pest animal species being addressed in concurrent projects and government reporting initiatives).
  1. Develop improved Australia-wide datasets for priority pest bird species for monitoring, evaluation, reporting and program improvement (MERI), to support regional NRM groups and land managers.
  1. Centralise data for introduced pest bird species from available information, and producing consistent mapping and data products for relevant regional, state/territory and national authorities to complement government initiatives for pest species data reporting.
  1. Deliver information products to relevant agencies, land managers, community- groups and regional NRM bodies, via government data libraries, portals, and web-sites.

This project was funded under the Australian Pest Animal Research Program (APARP).

Common myna impacts

Common or Indian mynas are now widespread throughout eastern Australia and are considered to threaten native biodiversity due to their territorial behaviours and nest cavity competition. The perceived impacts of the common myna are often based on unreliable information, and there is a lack of scientific research that confirms the bird’s actual impacts.

In 2008, the Invasive Animals Cooperative Research Centre (IA CRC) funded a PhD project undertaken by Kate  Grarock using Canberra as a case study. Prior to this research there was limited understanding of the impact the  common myna had on the abundance of native species. This project aimed to investigate:

  • the invasion history of common mynas in Canberra
  • long-term native bird abundance in Canberra before and after common myna establishment
  • the impact of the common myna in combination with habitat variation
  • the impact of the common myna on cavity nesting species
  • the effect of common myna trapping on their abundance

A case study on the impacts of common (Indian) mynas on other bird species and the effectiveness of community trapping in Canberra. Produced by the Invasive Animals CRC as part of the PestSmart series.

Common (Indian) Myna

IMFS1Common or Indian mynas (Acridotheres tristis or Sturnus tristis) are native to India and southern Asia. They are  popular birds in their source countries as crop pest control agents and as symbols of undying love associated with their habit of pairing for life.

Mynas have spread worldwide over the last 200 years. In Australia, common mynas are often confused with the native noisy miner (Manorina melanocephala) and sometimes with yellow-throated miner (Manorina flavigula) because of their similar size and appearance.

Mynas were listed among 100 of the world’s worst invasive species by the World Conservation Union (IUCN) in 2000. In Australia, common mynas are considered to threaten native biodiversity due to their territorial behaviours and nest cavity competition.

Modelling the distribution of vertebrate pests in New South Wales under climate change

This project, funded by the Invasive Animals Cooperative Research Centre on behalf of the New South Wales Department of Environment, Climate Change and Water, develops and applies tools to model the distribution and abundance of vertebrate pest species in relation to climatic and biophysical variables. Such models are needed to predict how the distribution of pest species may vary under a changing climate. We assembled a priority list of vertebrate pests affecting biodiversity in New South Wales (NSW) based on reported threats to species, populations and ecological communities. Feral goats, feral cats, red foxes, European rabbits, and feral pigs are the most common recorded threats to ‘endangered’ or ‘vulnerable’ terrestrial species in NSW, affecting 84.5% of threatened species listed.

This report covers these species—as well as cane toads, Indian mynas, starlings, wild dogs and wild deer. It uses quantitative and, where necessary, qualitative species distribution models to predict the distribution and abundance of these species using land manager desk-top surveys undertaken in 2004. Using the 2004 data, the species distribution models generally predicted the ranges of each species extremely well, but performed poorly in identifying areas where animals were considered to be at a high density. This may have resulted in part from data issues, including the effect of having multiple ‘observers’ and the scale of the analyses (5 km x 5 km grids).

These models were then used to predict the distribution and abundance of these pests under 2050 climate forecasts. Climate scenarios for 2050 were generated from four global circulation models (GCMs)—CSIRO, MIROC, ECHO and ECHAM—that performed reasonably well in modelling current Australian climate. As expected under a warmer climate, cane toads, which have tropical origins, are predicted to expand their range considerably (fourfold). Predictions varied more for species with temperate origins. Rabbits are predicted to generally decline in distribution and abundance. Foxes are predicted to increase in density in some areas and decrease in others, with their overall distribution changing little. Feral cats are predicted to have a slight decrease in abundance, but to maintain a similar range.

Animal Pest Alert – Common Myna

The Common Myna or Mynah (Acridotheres tristis) is also known as the Indian, Calcutta or House Myna. It is not native to Australia but has established populations in eastern and south-eastern Australia, as well as other countries worldwide.
The Common Myna has significant potential to spread further in Australia as populations are expanding south in Queensland and westwards across western Victoria and New South Wales. It is important to immediately report any found in the wild in areas where the species has not been seen before.
Contains information on identification, distribution, damage, pest potential and risk management.

Northern Tablelands Region Pest Management Strategy 2008-2011

The development of Regional Pest Management Strategies (RPMS) provide NPWS with a strategic approach to pest management across NSW. The strategy developed for each region provides a tool to broadly identify pest distribution and their associated impacts across the park system. It details priority actions for each Region, including actions listed in the PAS and TAPs, wild dog and feral pig control to protect neighbouring properties, and site-based weed control. It also allows resources to be allocated to high priority programs. The RPMS also recognises the
requirements of other related plans or strategies, such as Wild Dog Plans or Bush Regeneration Plans, that provide a more detailed approach to pest management.

New pest species continue to establish in the environment, either through the importation of new species into Australia, the spread of existing pests into new areas, or through the escape of domestic plants and animals. Prevention and early detection followed by eradication is the most  cost-effective way to minimise the impacts of new pests. The NPWS works with other agencies to prevent the introduction of new pests into the wild and to respond rapidly when new incursions occur. The response of NSW government agencies to new pests will be coordinated through the NSW Invasive Species Plan.

Protecting our national parks from pests and weeds

Invasive species (weeds and pest animals) represent one of the greatest threats to biodiversity around the world. They also cause financial losses to agriculture and other industries, and damage areas of cultural significance. Managing the impacts
of pests is therefore an issue of great importance for the managers of all land tenures. The problem requires sustained, long-term management to minimise the damage by pests to environmental, economic and social values.

The NSW National Parks and Wildlife Service (NPWS) manages pests within the state?s park system to protect native flora and fauna, maintain natural ecosystems and cultural heritage, and minimise the spread of pest animals and weeds to and
from neighbouring land. One of the keys to successful pest management is cooperation, and NPWS actively works with other agencies, private landholders and community groups.

The complete eradication of pests over wide areas of different land tenures is, however, rarely practicable. It is therefore necessary to prioritise pest management efforts and allocate resources to those areas where they will be of greatest benefit.
Priorities include those areas where new pest outbreaks occur, where threatened native plants and animals are at risk from the impacts of pests, and where there is a need to minimise the impacts of pests on neighbouring lands, such as farmland.

This report assesses our performance in managing pests within the park system, using data from a survey of all parks in NSW. The report also presents a number of examples and case studies, illustrating the complexity of pest management and highlighting excellence in NPWS pest and weed control programs and initiatives across the state.

Restraint and handling of pest animals used in research

Research involving pest animals may require the live capture, restraint and handling of individual animals. Wild animals may try to avoid capture, handling and restraint during which they are capable of inflicting damage to themselves and their potential captors. When physical contact is necessary, the safety of animals and operators should be the primary consideration.

Restraint and handling techniques must be appropriate for the species and minimise distress and the risk of injury to the animal. Inappropriate techniques may lead to major and possibly fatal physiological disturbances.

This standard operating procedure (SOP) is a guide only; it does not replace or override the legislation that applies in the relevant State or Territory jurisdiction. The SOP should only be used subject to the applicable legal requirements (including OH&S) operating in the relevant jurisdiction.

Review of the management of feral animals and their impact on biodiversity in the Rangelands: A resource to aid NRM planning

The Pest Animal Control Cooperative Research Centre (PAC CRC) was
commissioned by the Australian Department of the Environment and Heritage to
review feral animal management for biodiversity outcomes in the Rangelands. This
review was undertaken to help guide future Natural Heritage Trust spending on feral
pest management and control in the Rangelands.

The outcomes of the project were to:

  • provide options for the Australian Government to better target its action and
    investment to limit the impact of feral animals on biodiversity in the Rangelands
  • assist Australian Government officers to assess the adequacy and effectiveness of proposed feral animal projects in the context of the Natural Heritage Trust
    regional planning process
  • improve the regions’ ability to plan for and implement feral animal management
    in an integrated way to protect biodiversity.

The report achieves these outcomes by:

  • summarising relevant Australian Government, State and Territory legislation, as
    well as government and private arrangements (Section 4);
  • documenting existing methods for the management of feral animals (Section 5);
  • assessing the adequacy of these methods and their applicability to the Rangelands (addressed in Sections 5 and 7);
  • identifying gaps and opportunities for targeting Commonwealth action and
    investment in the management of feral animals in the Rangelands (Section 7).
  • developing a checklist for best practice planning and management of feral animals, to assist regions to develop programs and projects, and to allow Government officers to assess those programs and projects (Section 8)
  • listing rangeland feral animal management projects previously funded under the
    Natural Heritage Trust and other programs (Appendix 3)

The report begins with a major section that lists feral animal species found in the
Rangelands, summarising their distribution and impacts on biodiversity (Section 3).

Eradication of Common Mynas

The common myna (Acridotheres tristis) is native to the Indian subcontinent and Sri Lanka, but has invaded (with human help) many islands in the Pacific, Indian, and Atlantic oceans – as well as New Zealand, Australia and South Africa. In many Pacific islands, mynas are often the most common birds seen around towns and villages.
Mynas were first introduced to New Zealand, Australia, Fiji and Hawai’i in the late 1800s and from there they have been spread to at least 40 other Pacific islands. The last known liberations were on Mangaia Island in the Cook Islands about 1960, and on Tutuila Island in American Samoa in the mid-1980s. In New Zealand, mynas are now common throughout the North Island north of a line between Wanganui and Waipukurau, and no attempt has been made or is being planned to control their populations.

Mangaia is the second largest and most southerly of the Cook Islands and is the oldest island in the Pacific. It has a central volcanic plateau and, like many of the southern islands in the Cooks, it is surrounded by a 60 m high ring of cliffs comprised of fossilised coral or makatea. The island has a population of around 600 people. In 1996 the common myna population on Mangaia Island was estimated at 8,000?10,000 birds with most found in arable areas of the island.

The State of Australia’s Birds 2006: Invasive Species

The State of Australia?s Birds series presents an overview of the status of Australia?s birds, the major threats they face and the conservation actions needed. This fourth annual report focuses on invasive species.

Australia has hundreds of invasive plants and animals, both native and introduced. Some have been brought purposely, others hitchhiked. The majority simply took the many opportunities offered by human alteration of the landscape. Invasive species are considered to be the greatest threat to biodiversity after habitat loss; they also exact a massive toll on agricultural production. Some of the most abundant invaders compete with or prey upon native birds, or alter their habitat. Introduced predators, plants and competitors are conservatively estimated to contribute to the threatened status of some 95, 12 and 16 bird taxa (species and subspecies), respectively. Yet, invasive plants and animals may provide food and habitat for native birds in already degraded natural systems, and some native birds themselves become invasive.

Wildwatch2: Quest for Pests

There is an urgent need to find out more about the wildlife we share our cities, towns and farms with, so we can conserve and manage our diverse and unique animals.

The WildWatch2 survey aimed to find out which animals are perceived as problems, why they are a problem and how serious the problem is. This sort of information is invaluable for conservation, planning and wildlife management organisations to help direct research and extension effort.
View survey results, photo galleries, pest profiles, maps and more.
