GENTREE Final Conference 'Genetics to the rescue - managing forests sustainably in a changing environment'

Clare TRIVEDI - Royal Botanic Gardens Kew · United Kingdom :
Approaches to ensure ex situ conservation activities capture forest
genetic diversity: sharing experiences from the UK National Tree Seed
Project
Well planned seed bank collections play a vital complementary role to
in situ conservation and living ex situ collections of forest genetic
resources by protecting genetic diversity away from risks in the
environment, and providing accessible, well-documented germplasm for
research and experimentation. 
It is vital that such collections
capture the genetic diversity of a target species over the geographic
area in which it will be used.
The Millennium Seed Bank Partnership,
led by the Royal Botanic Gardens, Kew, comprises a range of seed
collecting projects worldwide. 
The UK National Tree Seed Project has
placed particular importance on the capture of intra-specific genetic
diversity for native trees and shrubs.
It has made seed collections
from over 6000 trees across 75 species from across the UK. The
project provides a useful case study for common challenges to capture
genetic diversity in collections, whether for long-term conservation
or more immediate use. 
Population geneticists have been involved
with the project throughout its lifetime from inception to
evaluation, with guidance provided via an expert advisory group and
commissioned genetic studies. Genetic approaches were incorporated
into development of the seed sampling strategy which, in the absence
of detailed knowledge of population genetics, uses biogeographic
zones as a proxy for genetic diversity and adaptation. 
The outcomes
of this sampling strategy were evaluated using a modelling approach
using simulations and geographic distribution data for the species
Fraxinus excelsior. 
The model estimates that UKNTSP ash collections
have captured >90% of all alleles present in Britain. 
Similar
results have been found from a laboratory study on UKNTSP collections
of yew Taxus baccata.
The UKNTSP has shared data with projects
working to identify Gene Conservation Units and Registered Seed
Stands and collections are available to researchers, including those
working on tree improvement or to understand variations in traits
over geographic areas.
As a result the UKNTSP has been a key catalyst
for development of the first Strategy for UK Forest Genetic
Resources.]]></string></description>
