Butt rot damages the xylem tissue that carry water and nutrients upward to the upper portion of the trunk and the branches. The pathogen, a fungus, attacks the unprotected stem butt above the roots, in the moist areas right under the soil. 

Butt rot is not limited to Yakal (Shorea astylosa): the fungal infection can affect many different tree species. Yet, this fungi have targeted and killed only Yakals, even far apart, sparing so far any other tree in between.
