Tropical Trees and Landscapes

Our objective is to mobilize and build capacity, carry out applied and basic research, provide training and education, and advisory services within the research area of tropical trees and landscapes.

We provide extension in conservation and utilisation of genetic resources of trees that will improve access to reproductive material for all kinds of tree planting and habitat restoration, including agroforestry, afforestation, and forest and landscape restoration in the tropics.

IGN present some of our results of the research on species, seeds and planting in the form of computer-based tools.

As a supplement to our ordinary publication series, we have chosen to develop and present some of our work in a more interactive way, where users have the opportunity to 'browse' the material and identify issues of their particular interest.  

  • Vegetation and climate change in Africa: Vegetation map for Africa
    A high resolution digital vegetation map for land use planning, natural resource management and conservation of biodiversity in Eastern Africa (VECEA).
  • The Resources for Tree Planting Platform
    The Resources for Tree Planting Platform explains how to go about sourcing good quality tree planting material for growers carrying out land restoration, agroforestry, plantation establishment and other tree planting activities.
  • Global Tree Knowledge Platform The Global Tree Knowledge Platform is all about the trees in ‘treed’ landscapes. Its purpose is to support the better use of tree species – to promote the right tree in the right place for the right purpose, e.g. with access to interactive tools on ‘What to plant where’ in different tropical countries – to bring greater benefits to humans and the environment.
  • The Agroforestry Species Switchboard The Agroforestry Species Switchboard is a “one-stop-shop” to retrieve data about any particular plant species across a wide range of information sources, documents the presence of 290,235 plant taxa (current names and synonyms) at genus, species and infraspecific levels
  • Potential Natural Vegetation of South-Western and Central Kenya 
    A tool for the selection of indigenous tree species. 
  • Gmelina arborea trials
    The website is a compilation of published articles, results and assessments from 27 of these trials.

Laboratory and trials

For our research we use the laboratory:
DNA laboratory - Genetics and diversity
We also have a share in several trials.


Elective courses in AgroforestryTropical Botany and Tropical Forest Restoration are offered under the educations Forest and Nature Management , and Environment and Development and can be chosen as part of other educations as well, e.g. Global Forestry.

Collaboration and networks

We collaborate with both the private and public sector especially in Africa and Asia.
