Hardwood field experiment: Progress report 1977-82
D J Dickinson, J F Levy
The international hardwood field experiment was planned in 1976 and set up in some 30 different sites around the world. The test stakes include 4 reference species common to each site and in most cases at least 2 species of local importance. It was hoped that a picture of performance of a range of economically important species would be built up and at the same time provide vital background information for people currently engaged in hardwood and soft-rot research. It is felt that these aspirations are more than being achieved and that as time proceeds this trial will prove invaluable in developing our knowledge of wood preservation on a world wide basis. Obviously it proved impossible to set up such a large trial simultaneously. Different sites also inspect their trials at different times and so the data presented is for different periods dependant on the site. For the reference species table 1 gives the latest data from each site and should be considered with report IRG/WP/3164 which gave information at earlier dates. Table 2 gives the performance of the other species for each site and, where stakes were available, for the master site (33) at Imperial college. No attempt has been made to analyse or comment on the results at this time. It is felt that this is a progress report for comment on by the sub-group. However, it is felt that together with the comments received these results should be duly considered for publication elsewhere.
