Something else to add to the long list of problems that can afflict field genebanks:
Hordes of moles have penetrated into the MTT Agrifood Research Finland plant gene bank in Laukaa during the winter.
A lot of damage was done to fruit tree saplings in particular. Fortunately, there is a back-up site, but not all material is safety duplicated. More protective measures are to be introduced. Also, there seems to be a lot of cryopreservation work going on at Laukaa, so maybe in time there will be an added level of protection. MTT Agrifood research have a nice pamphlet on Finnish agrobiodiversity and its conservation.
