Sharp-eyed plant experts tramping in the Tongariro National Park have spotted butterwort - a carnivorous plant that is classed as an invasive weed and poses a danger to native wetland species.
The Department of Conservation says it's likely that someone passionate about the insect-eating specimen has deliberately introduced it.
Tongariro's senior ranger for biodiversity, Alison Beath, is asking people to keep an eye out for other incursions and to report them to DoC. They are likely to be in accessible damp areas - where the plants thrive - next to tracks or roads. The plants were spotted last month on the Taranaki Falls Track.
R&D Conference on Invasive Alien Species Management and Biosecurity Measures in the Asia Pacific Region
Invasive Alien Species (IAS) are one of the major threats to biodiversity worldwide and is viewed as cause of extinction of the endemic or native species in a particular country where they have been introduced. These results to a phenomenon called bioinvasion of natural habitats and puts to risk the existence of our indigenous flora and fauna either through competition for food or space. This brings forth an emerging concept called biosecurity which is globally significant because of the risks they pose to the economy, environment and human health.
Numerous international instruments have been developed to address IAS and the most comprehensive is the Convention on Biological Diversity (CBD) which calls on parties to prevent the introduction, control or eradicate those alien species which threaten ecosystems, habitats or species. At present, IAS occurs in different taxonomic groups. Some species have in fact been purposely used for various purposes such as reforestation, food production and biological control of other unwanted organisms and have, to some extent, been part of the country’s natural landscape.
There is, however, a dearth of information in terms of the range of distribution and impacts of many of these IAS in natural ecosystems. Threfore, this conference aims to provide a forum for the exchange of research and development information and technologies on the status, control and management of invasive alien species (IAS) in the Asia-Pacific region.
Expected Outcomes of the conference:
Enhanced R and D partnership and cooperation between and among Asia-Pacific countries including dialogue and development partners particularly in coming up with strategies on sustainable management and/or eradication of invasive alien species;
Institutional and capacity developments to be pursued among Asia-Pacific countries including dialogue and development partners in eliminating risks and negative effects of IAS introduction such as threatened human health and safety, environmental loss and substantial economic damage; and
Improved/strengthened strategies and policies to address issues on IAS which globally is one of the major drivers of biodiversity loss.

9th International Workshop on Biological Control and Management of Eupatorieae and other invasive weeds:
This workshop is organized under the auspices of the International Organisation for Biological and Integrated Control (IOBC) and CABI Southeast Asia. The first workshop was held in 1988 to facilitate the management and biological control of Chromolaena odorata in resource-poor tropical and subtropical countries. In 2003, the scope of the workshop was expanded to include closely related species such as Mikania micrantha, while retaining an emphasis on the tropics. Malaysia has been selected as the host country for this 9th workshop, the first to be held in Southeast Asia. The tribe Eupatorieae, which includes Chromolaena odorata and Mikania micrantha are widespread in Southeast Asia and have significant economic impacts on agriculture, the environment and livelihoods. The entire region has been shown to be highly climatically suitable for the weeds. Other species of invasive alien plants for which there are good biological control agents available and which could be included in this workshop if the interest exists, include Salvinia molesta and Pistia stratiotes.

The Pacific Invasive Ant Toolkit is a collection of resources to help prevent and control invasive ants in the Pacific. We call this the PIAT for short.
The PIAT is mostly targeted at helping developing and remote Pacific Nations, who often do not have access to pest control locally and depend on outside help. But anyone is welcome to use it.
We decided that the PIAT was needed as the resources available to deal with invasive ants were in many different places and sometimes hard to find. So some of the resources you will find here have been specifically developed for PIAT, but others are available in other places. We always provide links to the original sources of information.
An international team of scientists, involving entomologists, conservation biologists, agro-ecologists and geographers, has just revealed how on-farm biological control can slow the pace of tropical deforestation and avert biodiversity loss on a macro-scale. The case study concerns biological control of the invasive mealybug Phenacoccus manihoti with the introduced host-specific parasitic wasp Anagyrus lopezi in Southeast Asia.
With the huge volume of international trade, sea containers can become vehicles for plant pests and diseases to spread into new areas. The International Plant Protection Convention (IPPC) has therefore set up a special Sea Containers Task Force (SCTF) to deal with this specific issue. The SCTF’s second meeting recently took place from 5 to 9 November 2018 in Shenzhen, China
The International Year of Plant Health 2020 and the IPPC’s work in protecting plants from invasive alien species were highlighted during a side event at the 2018 Conference of the Parties to the Convention on Biological Diversity (CBD - COP 14) held in Sharm El Sheikh, Egypt.
Forests around the world are experiencing invasions of thousands of different non-native species, including nearly every type of plant, animal and other types of organisms. Globalization is the main cause of the biological invasion issue, with increasing trade and travel causing accidental movement of organisms. A variety of methods are available for managing forest invasions, either by preventing the arrival and establishment of new species or by managing established populations. In the future, forests around the world will likely be exposed to increasing numbers of non-native species and effective management requires international cooperation and interdisciplinary integration.
Last week CABI launched the full version of its invasive species Horizon Scanning Tool, a free and open access online resource available via the Invasive Species Compendium that helps users make decisions about invasive species and identify possible risks in countries, provinces and states.
Following beta testing, the tool now includes new features and improvements such as an additional country filter based on trade data, enhanced sharing of horizon scans, improved CSV output and the integration of habitat data into the data sheets.
While people elsewhere in the state will plant millions of tree saplings marking World Environment Day on Tuesday, a group of greens and farmers in Wayanad are set to uproot over one lakh invasive plants that have been posing a threat to the forest ecosystem in the hill district.
Expressing concern over the increase in the import of ornamental fishes to the country, which is posing a threat to India’s native fish populations, the National Biodiversity Authority (NBA) has urged the government to come up with quarantine facilities at major seaports and airports.
Managing invasive species could benefit 95 per cent of Endangered and Critically Endangered amphibians, birds and mammals that live on islands, according to a study involving researchers from the IUCN Species Survival Commission (SSC) Invasive Species Specialist Group and IUCN Member Island Conservation, published today in the journal Science Advances.
Restoration projects to remove invasive plants can make a positive impact on native plant species. But a new study featured in the journal Invasive Plant Science and Management shows restoration has an additional benefit. Removal of invasive species growing alongside a stream or river can also improve the biodiversity of aquatic organisms.
As invasive species are threatening ecological habitats throughout the U.S. and Canada, the role of Indigenous nations as environmental stewards has often been overlooked, according to a Dartmouth-led study published in the current issue of American Indian Quarterly.
A new study published today in the Journal of Applied Ecology, and co-authored by several IUCN scientists, identifies priority invasive alien species that require urgent action across the EU and proposes a systematic, proactive approach to select species for risk assessment, in order to assist EU policy implementation.
Armies of microbes that are invisible to the naked eye battle it out to determine whether exotic marine plants successfully invade new territory and replace native species, UNSW Sydney-led research shows.
North America’s most widespread and valuable ash tree species are on the brink of extinction due to an invasive beetle decimating their populations, while the loss of wilderness areas and poaching are contributing to the declining numbers of five African antelope species, according to the latest update of The IUCN Red List of Threatened Species™.
