The Rural Voice, 2004-11, Page 42Woodlot Management have in southern Ontario, it is usually recommended that basal area not be reduced below 20 square metres per hectare (87 square feet per acre). It is also recommended that not more than one third of the basal area be removed in a harvest or thinning operation to avoid excessive disturbance. Of course it is usually also a goal to concentrate growth on the best quality stems by removing poorer stems in thinning and improvement cutting operations. There are several options for measuring basal area. The most common, easiest and most accurate is a wedge prism, available from most forestry supply companies for about $60. Another simple (and the cheapest) approach is an angle gauge. An angle gauge can easily be crafted from materials commonly at hand. A more time-consuming option would be to measure all trees in a fixed area plot, calculate the basal area of trees in the plot, then extrapolate to an acre or hectare. Regardless of the approach taken to measure it, basal area is a tool that should be used to help determine appropriate management activities in your woodlot.
