findings of this Assessment. Indeed, the 
Assessment received media coverage in over 
100 countries, with over 5,000 press articles, 
in the weeks following approval - testament 
to the meticulous and tireless work of the 
IPBES communications team.
We are also grateful to the Government of 
Japan, which generously hosted the technical 
support unit at the Institute for Global 
Environmental Strategies (IGES) and the first 
author meeting, and all the governments 
who nominated and supported experts. We 
thank Aarhus University (Denmark) and the 
University of Concepcion (Chile) for hosting 
our author and/or summary for policymakers 
meetings. We thank the secretariat of 
the Convention on Biological Diversity who hosted our first 
dialogue on Indigenous and local knowledge in Montreal, 
Canada. We would especially like to acknowledge the support 
of our home institutions and governments: the UK Centre for 
Ecology & Hydrology (United Kingdom); the Faculty of Forestry 
Sciences, University of Concepcion and Institute of Ecology 
and Biodiversity (Chile); and Ontario Tech University (Canada). 
We have appreciated the encouragement given to us from 
them and the value they have placed on the work we have 
been collaboratively leading.
Our gratitude goes to Bureau members Douglas Beard and 
Sebsebe Demissew Woodmatas, for co-chairing the sessions 
on the Assessment at the IPBES 10 Plenary (28 August - 
2 September 2023, Bonn, Germany) which approved its 
summary for policymakers and accepted its chapters. We also 
thank MEP co-chairs Luthando Dziba and Shizuka Hashimoto 
for their roles in facilitating discussions.
We would lastly like to thank all our friends and relatives who 
supported us throughout this demanding assessment process. 
This work would not have been possible without their love, 
endless support and understanding.
The dedication and contributions of all those mentioned above 
ensured the outcome of the Assessment of Invasive Alien 
Species and their Control as a unique, robust and rich report. 
It has been a privilege to have the opportunity to collaborate 
with so many inspiring people, in all their many and varied 
roles. We are confident that the Assessment will be impactful, 
increasing global awareness of the significant threats to 
biodiversity and human communities posed by invasive alien 
species and, very importantly, what can be done to prevent 
and control them.
