This project is funded by grant 13007 from the Darwin Initiative to the Royal Botanic
Garden Edinburgh and its three Laotian partners, namely the Forestry Research Centre,
part of the National Agriculture and Forestry Research Institute, the Department of
Biology, Faculty of Science at the National University of Laos and IUCN Lao PDR.
We are particularly indebted to the Watershed Management and Protection Authority
of Nakai Nam Theun National Protected Area which gave permission to our project to
train botanists and collect plants within their area.
We thank the Director of the National Agriculture and Forestry Research Institute
and the Dean of the Faculty of Science, National University of Laos who have welcomed
this project and ensured that it had all the necessary permits to run smoothly. In Lao PDR
we should also like to thank Mr Banxa Thammavong, Mr Singkone Saynhalat and Ms
Phayvone Phonphanom from the Forest Research Center, Mr Soulivanh Lanorsavanh
and Ms Phetlasy Souladet from the National University of Lao PDR for their enthusiastic

electronic version of his publication ‘Checklist of Lao Plant Names.’ Joost Foppes and
Martin Greijmans from Stichting Nederlandse Vrijwilligers (SNV) and Pierre Bonnet
and Pierre Grard from the Orchisasia and BIOTIK projects also provided knowledge,
advice and support.
Thanks are due to Andrew Ingles and the Bangkok office of IUCN for their support of
our collaboration with IUCN Lao PDR. We gratefully acknowledge the support, advice
and hospitality of Dr Kongkanda Chayamarit and Dr Rachun Pooma at the Bangkok
Forestry Herbarium.
We also acknowledge the help of many experts on plant groups who have named
plants for us and contributed information. Among the many people who have
contributed their time and knowledge are Paul Keßler, Colin Ridsdale, Frits Adema,
