Tree Seed Quality Guide 

This guide addresses  different elements of tree seed quality, and measures which can be taken to produce or access the best available material for planting.

Tree Seeds for Farmers Toolkit

The prime objective of the toolkit is to provide information and examples of how the quality of seeds and seedlings can be maintained from collection to field planting for the great diversity of agroforestry species that are useful to small-scale farmers.

 The toolkit was developed recognizing the wide range of actors and stakeholders that are involved in scaling-up agroforestry systems. Its format is designed to answer the questions that various actors may have in relation to seed production. It is based on a review of existing documentation and extension materials on seed production. Useful references to augment the toolkit information are also provided.

 

Use of vegetation maps to infer on the ecological suitability of species using central and western
Kenya as an example
 

Potential natural vegetation (PNV) has been defined as the vegetation structure
that would become established if all successional sequences were completed
without interference by man under the present climatic and edaphic conditions, including those created by man

PNV maps are a promising tool for bringing indigenous tree species into use within anthropogenic landscapes, but such maps have unfortunately been ignored largely by the agroforestry world.

The purpose of this Potential Natural Vegetation (PNV) of eastern Africa is to document how the utility of PNV maps can be increased

Good Nursery Practices_A Simple Guide 2010

In order for farmers and rural organisations to establish effective nurseries, it is important to provide nursery managers with the simple technical information they need for establishment and management of facilities. This is the role of this publication.

Vegetative tree propagation in Agroforestry

These training materials have been developed in support of a one-week practical training course on vegetative propagation of agroforestry trees.

Tree Diversity Analysis: A Manual and Software for Common Statistical Methods for Ecological and Biodiversity Studies

Effective data analysis requires familiarity with basic concepts and an ability to use a set of standard tools, as well as creativity and imagination. Tree diversity analysis provides a solid practical foundation for training in statistical methods for ecological and biodiversity studies.

This manual arose from training researchers to analyse tree diversity data collected on African farms, yet the statistical methods can be used for a wider range of organisms, for different hierarchical levels of biodiversity and for a variety of environments - making it an invaluable tool for scientists and students alike. The manual introduces a powerful software programme, Biodiversity.R, that is capable of performing all the statistical analyses described in this book. The software is provided on CD.

 

Tree Seed Source Re-classification Manual

This manual has been developed to improve the documentation of seed  and adapt the documentation system to include farmland Agroforestry seed sources and also harmonize seed source documentation

Multiplication, that's the name of the game - Guidelines for seed production of agroforestry trees 

The demand for tree seed of species and provenances that are particularly
suited for specific agroforestry practices con be very high - and
often demand outstrips supply When this happens, formers either do not
plant trees or use whatever seed is available, even if it is inferior.

This article by Ian Dawson and James Were suggests useful guidelines for
producing good tree seed. The guidelines are geared to extension
organizations, researchers and others involved in spreading agroforestry
techniques.

Germplasm from trees – some guidelines

The process of domestication begins with the farmers. The farmers, the ultimate users and beneficiaries of improved agroforestry trees, are therefore the only ones who can  tell researchers which trees they value the most, why these ore their 'priority species', what tree products benefit them  most and how they would like to see the trees 'improved'.  It is only after these priority species have been identified  that germplasm collections can have the impact

In  this article,Ian Dawson and James  Were offer readers some step-by-step guidelineson how to go about making collections

Nursery Manuals

In this book, Kevyn Wightman has synthesized a wealth of information about nursery practices, and added her own formidable experience and insights to offer very useful guidelines for managers of community and project nurseries. The manual includes not only what to do, but also why to do it. Nursery managers and others will find this a valuable reference

Common antimalarial Trees and Shrubs of East  Africa

Malaria remains a major public health problem and a health concern which affects hundreds of millions of people, particularly in tropical African developing countries
 Medicinal plants have been playing a vital role in the treatment of malaria for thousands of years,  and many well-known drugs listed in the modern pharmacopoeia have their origins in natural sources-mainly from plants. In malaria endemic countries traditional medicinal plants are frequently used to treat malaria.
In this resource, the 22 tree and shrub species chosen for description here have been assigned
by traditional medical practitioners, rural communities and scientists as among
those that have potential for further study and development as crops by smallholders

in East Africa, although this list should  not be considered as exhaustive of all useful antimalarial plant species in the region. Extracts from a few of the species described in this guide (e.g., Artemisia annua, Azadirachta indica and Warburgia ugandensis) are already more widely used commercially for treatment (and/or prevention) of malaria, especially of course artemisinins.
