Botanic Gardens Conservation International
BGCI provides a global voice for all botanic gardens, championing and celebrating their inspiring work. We are the world's largest plant conservation network, open to all. Join us in helping to save the world's threatened plants.

Building the network

The IPSN aims to build on the experiences, expertise and resources of similar initiatives and research projects that have already seen great success. Therefore as well as extensive collaboration amongst the EUPHRESCO partners, the network will link with other organisations involved in plant health and protection around the world, as well as botanic gardens and arboreta.

We are currently in the process of collating information on similar initiatives and research projects as well as databases, training materials, protocols and information relating to plant pests and diseases. Similarly we are also looking for examples of best practice from botanic gardens and arboreta who have established programmes / initiatives linked to plant biosecurity. See below for a number of key examples of the kind of things we are looking for.

If you have any information, links or contacts for any of the above please email Ellie Barham (

Project Participants

The IPSN has already been fortunate enough to establish participation from a number of key institutes from around the world who are involved in similar sentinel plant work:


The Sentinel Plant Network is a collaboration between the American Public Gardens Association (APGA) and the National Plant Detection Network (NDPN) in the U.S. The network’s mission is ‘to contribute to plant conservation by engaging public garden professionals, volunteers, and visitors in the detection and diagnosis of high consequence pests and pathogens’. It is well established within the U.S. with, to date, over 150 member gardens representing 43 states and including gardens within the District of Columbia, and three Canadian provinces. Find out more about the U.S. Sentinel Plant Network here


The Better Border Biosecurity (B3) group from New Zealand ran the Expat Plants Pilot Project which identified teams of scientists in Europe, North America and Australia who were able to detect pests and diseases amongst plantings of New Zealand endemic species. B3 now wishes to build on this earlier project by contributing on behalf of New Zealand to the IPSN. Find out more about B3 and their involvement in the IPSN here.


In recent years, mainly due to the devastation caused by a number of major pest and pathogen outbreaks, plant (particularly tree) health has seen a boast in interest from the press and general public. There is an abundance of resources that have been created to promote understanding and awareness of biosecurity issues to a wider audience. The websites listed below contain some great resources including fact sheets, games and activities which give information about local, regional and/or global threats and biosecurity issues in genera:



BGCI's PlantSearch and GardenSearch databases will provide valuable tools to support the development of the network. All gardens that join the IPSN will be asked to upload their plant collection records onto the PlantSearch database so that we can find host plant species and thus identify potential monitoring sites and/or research opportunities. Gardens do not need to be a member of BGCI to upload information and the location of species in collections is not shared publicly. For more information on how to upload collections please click here

There are a large number of databases already in existence documenting the major threats to plant health around the world. The IPSN aims to promote and, where possible, link with these databases. Some great examples are listed below:
