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

: Genetic management of European ash (Fraxinus excelsior) forests in
the face of ash dieback through enrichment plantings
The emerging infectious pathogen Hymenoscyphus fraxineus has been
decimating common ash (Fraxinus excelsior) populations throughout
Europe for more than two decades.
This causes socio-economic losses
andecological problems as well as concerns over the future existence
of the species in European forest ecosystems. 
Previous studies have
reported heritable genetic variation in ash dieback susceptibility,
suggesting that ash may possess genetic potential to recover in the
long run via natural selection. 
Enrichment plantings with tolerant
trees based on the offspring from selected and tested ash trees can
support the recovery process by maintaining the species in the forest
and allowing them to disperse their seeds and pollen. 
However, the
efficiency of such a strategy will depend on the reproductive fitness
of surviving trees and the extent of gene flow between planted and
old trees. 
We therefore investigated seed and pollen dispersal at two
different sites, Rösenbeck (Germany) and Valby Hegn (Denmark). 
We
further tested the hypothesis that healthy tolerant trees have higher
reproductive success than trees with high disease susceptibility in
the populations severely affected by ash dieback. 
Here we used health
assessments combined with microsatellite data from a clonal trial at
Tuse Næs (Denmark) and the mixed continuous forest of Valby Hegn. 
We
found that ash trees had spread seeds and pollen several hundred
meters into the surrounding, managed forests.
We also found that
healthy trees had superior reproductive success. Our results suggest
that natural recovery can be supported by enrichment planting of
seedlings propagated from tolerant ash genotypes. 
Human intervention
may therefore prove valuable to ensure the future existence of ash in
European forests when sound genetic principles are integrated into
management practices.
