This paper presents the results of the study to assess the degree of degradation caused to wood during open air storage at Changa Manga forest plantation. Four different species viz ; Shisham (Dalbergia sissoo) , Mulberry (Morus alba) , poplar (Populous spp.) and Semal (Salmalilia malabarica) where tested for loss of strength in relation to storage time. The results indicated that both popular and semal were severely decayed even after a storage period of few months while the other two species were least affected.
