The availability of fibre from private land in Alberta has been largely ignored because of a surplus from public land. However, much of this surplus has been allocated in recent years, so that fibre from private land is quickly becoming a potentially important wood supply for primary forest products firms in Alberta. This study obtained information from 38 land owners in west-central Alberta through a personal interview survey conducted in May 1989. Respondents were asked questions on the physical characteristics of their land, production costs from harvesting, questions related to their socio-economic conditions, and uses of their forest lands. The study also used a model to evaluate the relative importance of a number of variables for their effect on a landowner's decision to supply fibre now and in the future. A discussion of market structures for private fibre is presented, with the presence of transactions costs to both landowners and firms in procuring private fibre analyzed in light of the modelling results.
