Windthrow is a natural disturbance agent which disrupts forest and stand level plans in British Columbia (BC). The objectives of this thesis were to: i) review the factors contributing to windthrow risk in BC, ii) investigate patterns of stem growth in conifers following thinning and consider their use for diagnosing windfirmness; and iii) present a diagnostic method of assessing windthrow.

The deployment of transgenic crop plants containing B.t. toxin genes is likely to be an effective method for inducing resistance in agricultural pests. Treated habitats are the locations where Bt insecticides (usually a mixture of spores and crystals) have been applied.

In Canada, Meadows () estimated that approximately viable Btk spores per ha were released in a typical spray operation to control spruce budworm (Choristoneura fumiferana).
