Top dying of sundri (Heritiera fomes Buch.-Ham.) in the Sundarbans is considered to be the most severe of all the diseases of tree crops in Bangladesh. The wood samples from sound, moderately affected and severely affected sundri trees from three different tree heights for every individual test were collected and their respective physical properties were examined to make a comparison. It was found that density decreased with the increase of disease severity and was found 5% for both the cases. The volumetric shrinkages also increased due to top dying and were found 6.42% and 3.34% higher for moderately affected and severely affected trees respectively. Similarly the initial moisture contents also decreased due to top dying and were found 5.34% and 16.19% lower for moderately affected and severely affected trees respectively.
