Abstract

The results of point sampling conducted, probably for the first time in India, in 45.32 hectare chir stand of Champion Block, New Forest, using wedge prisms of basal area factors 10, 15, 20 and 25 in British units (2.296, 3.444, 4.591 and 5.739 in Metric units) are presented and compared with plot sampling of the same area. The study has demonstrated that prisms with B.A.F. 10 or 15 are most suitable for enumerating the stand. The results also indicate that point sampling based on 20 to 25 objectively selected sample points in 30 to 40 year old chir stands could furnish estimates of basal area per hectare and number of stem. per hectare with standard errors of 5 and 6 per cent of the true values Respectively.
