Microsatellite markers similar to those used in human forensic investigations are being developed for western red cedar (Thuja plicata). They will be used to match DNA from illegally harvested tree stumps to suspected stolen wood. A method to extract DNA from wood samples is described, an example of a primer pair suitable for individual tree genotyping is given, and its application in forensic analysis is described.
