Intro:The bark of a tree is the portion between the inner living phloem and the outer compressed cellular structure which has lost its activity as conductive tissue. The use of tree bark as a mulch has resulted in weed supression (1). It has been processed into useful garden and farm products (4). It has been accepted as a marketable product in the form of soil amendments and decorative mulches used in landscaping (3). Recent studies conducted in P.F.I. (2) show that chir pine bark can be used as a tanning material. Bark volume estimation will thus help in the development and utilization of this material. 683 chir pine trees constitute the basic data for these tables.
