The use of selective media for studying the colonization of wood in ground contact by microorganisms

IRG/WP 186

C P Clubbe

In October1976 a field trial was set up in order to monitor the progressive colonisation of wood in ground contact using orientated small stakes of Scots pine (Pinus sylvestris) and birch (Betula sp.) (30 x 45 x 250 mm³). Half the number of each species were treated with a 1% solution of CCA by a vacuum impregnation process. All the stakes were coated on three sides with an epoxy-resin sealant to enable the ingress of organisms from the single uncoated face (the outer 30 x 250 mm² tangential longitudinal face) to be monitored, in depth. The stakes were then set up at the Imperial College Field Station at Silwood Park in an adjacent plot to the one that now contains a complete set of replicates for the IRG Field Trial.
