Commitments towards achieving the Honolulu Challenge

                                                                    Honolulu Challenge

The Honolulu Challenge will only be achieved if countries and organisations take the bold, yet practical, measures necessary to safeguard biodiversity and human wellbeing from the devastating impacts of invasive alien species. Below are those commitments that have been made, so far, to meet the aim of the Honolulu Challenge.

The New Zealand Government commits to making New Zealand predator free by 2050.

Specifically, that the country will be free of the most damaging invasive alien species (rats, stoats and possums) by 2050. The New Zealand government will work in partnership with others (indigenous people, communities, NGOs, business, philanthropists) to achieve this goal.

As an interim goal, by 2025 the Government has committed to:

1) Eradicate all pests from all island nature reserves.

2) Develop a method for eradicating one of the key target pests from mainland New Zealand.

Defra logoThe UK Government commits to spending £2.75 million on assisting its Overseas Territories to develop comprehensive biosecurity for invasive non-native species as well as making a substantial contribution to the eradication of mice from Gough Island to save the critically endangered Tristan albatross and Gough bunting as well as other threatened species.

Specifically, this involves a commitment of £1 million towards developing comprehensive biosecurity for the Overseas Territories by providing them with access to UK expertise on risk analysis, pathway management, pest identification, horizon scanning, contingency planning, rapid response capability and species management.  The Government also commits to making a £1.75 million contribution to the eradication of mice from Gough Island to save the critically endangered Tristan albatross and Gough bunting as well as other threatened species on the World Heritage site.


The Australian Commonwealth Scientific and Industrial Research Organisation commits to doubling of long term co-investment with partners into invasive species management.


Specifically, CSIRO will double its long term co-investment with partners into invasive species management plans for national priority pests, weeds and diseases, including biological control solutions where existing or applicable in the future and make our science, data and experience publically available.

This will include trialling a global first biological control program against an aquatic vertebrate pest (European carp) within the next 5 years to push the boundaries of this application of this approach.

In addition, CSIRO will double its investment in the risk assessment, public acceptability assessment, required new regulatory mechanisms and technical development of novel innovative technologies (genetic and robotic) and their application for the prevention, eradication and management of national priority pests, weeds and diseases to improve the cost-effectiveness of IAS response strategies.


The BirdLife partnership aims to remove invasive alien threats from at least a further 35 high biodiversity islands worldwide by 2020.


Specifically, by 2020, the Birdlife Partnership seeks to increase the biodiversity value of at least 35 important sites by removing harmful invasive alien species from islands in the European, Pacific and African regions, as well as certain UK Overseas Territories. Additionally, the Partnership will work with relevant administrations at all levels to support the development and implementation of biosecurity policies that will safeguard these sites, and others, into the future.


Island Conservation commits to protect more than 100 threatened species at risk from invasive species on 40 Islands by 2020.


Specifically, by 2020 Island Conservation is committed to supporting and working with island communities, stakeholders, governments, and NGO partners around the world to protect more than 100 populations of threatened species by removing invasive species on 40 islands. We will seek funding, policies, plans, and partnerships to advance these, and others’, island conservation interventions. The dividends from this work will also benefit the local peoples’ livelihoods and wellbeing, ecosystems, and 1000s of native island species.


The Grupo de Ecología y Conservación de Islas, A.C. (GECI) commits to remove invasive mammals from all islands of Mexico by 2030.


Specifically, GECI will work closely with federal government, academia and, most importantly, with local communities, to remove all invasive mammals from all of Mexico’s islands by 2030. The goal is to eradicate 70 populations of invasive mammals—particularly rats, mice, cats and goats— from 34 islands. In addition, GECI will promote the implementation of a National Program for Island Biosecurity. This ambitious target builds on the successes achieved over the past two decades where thanks to a strong collaborative network—federal government, academia, local fishing cooperatives, and with civil society at the core—Mexico has successfully eradicated 58 populations of invasive mammals from 37 Mexican islands, which represents more than 51,000 hectares restored.

“The Secretariat of the Pacific Regional Environment Programme commits to developing two significant Pacific multi-country invasive species projects which will be operational by 2020.

Specifically,  SPREP will double the volume of operational multi-country projects by 2020. This will include Increasing the capacity of the SPREP Invasive Species Programme to further assist Pacific countries and territories, including the development of the regional support service with partners and mechanisms to improve regional invasive species information and knowledge management.”


The Biodiversity Consultancy (TBC) commits to helping its private sector clients identify threats posed by invasive alien species, prevent their introduction, and mitigate their impacts; in line with best practice standards such as the International Finance Corporation Performance Standard 6.


IUCN and its SSC Invasive Species Specialist Group (ISSG) commits to doubling the content of its online databases and decision support tools by 2020, and making this knowledge accessible through one single data source to those working towards conservation and development goals

Specifically, by 2020, IUCN will increase the species accounts on its Global Invasive Species Database (GISD) creating accounts for all IAS that impact threatened island plant species, bringing together in one place information on impacts, management, pathways of introduction, and distribution within islands and protected areas. IUCN will also publish and maintain validated checklists of introduced species for 195 countries in the Global Register of Introduced and Invasive Species (GRIIS) as part of the CBD GIASI Partnership, and will develop and implement a standard classification of the environmental and socio-economic impacts of invasive alien taxa. IUCN will also continue to maintain the indicators for CBD Target 9, and commits to developing an indicator for SDG target 15.8 on IAS. IUCN will publish at least two IAS guidance documents by the end of 2018, one to support island states in developing comprehensive and effective invasive alien species management plans, and another alongside the CBD on the application of classical biological control measures. IUCN also commits to, by 2020, developing and seeking funding for at least one regional scale project focusing on developing capacity and measures to prevent the introduction of, and manage priority IAS.
