Assessing the potential and constraints for hybrid poplar plantations in the semi-arid regions of British Columbia

不列颠哥伦比亚省(BC)需要额外的木材供应。杂交杨树生长迅速，正在 广泛分布在北美。不列颠哥伦比亚省南部内陆的气候为 杂交杨树的产量。杂交杨树的主要问题之一是足够的土壤肥力，抗寒性 以及高用水需求。在半干旱地区，如果在洪泛平原种植杂交杨树可能是可行的，因为 浅层地下水可能是树木可以接触到的。然而，溪流/河流土壤的空间变异性 洪泛平原可能是高度多变的。为了选择正确的杂交杨树无性系，土壤肥力的差异 在泛滥平原内应该是已知的。因此，如果杂交杨树要成为BC的一个可行的纤维来源 对于半干旱地区，我们必须了解位于其中的洪泛区存在什么水平的空间变异性 半干旱地区。 该项目将由汤普森·里弗斯大学和SK7ain Ventures Ltd.合作完成。 Ventures Ltd.是一家木制品公司Norbord Inc.和Skeetchestn Indian的合资企业 乐队。潜在的选址位于Skeetchestn土地(公元前死亡河的泛滥平原)。诺博德公司 已经同意在收获时购买这些木材。然而，要使这种伙伴关系成为现实，研究是 需要确定在半干旱土地上成功种植和收获杂交杨树的可行性。 研究的目标是： 确定位于不列颠哥伦比亚省Deadman河泛滥平原内的土壤的变异性和肥力。 将最好的杂交杨树无性系与该地区的土壤和气候相匹配。 C.在汤普森-里弗斯大学(TRU)、 Skeetchestn印度乐队和NordBord Inc.

British Columbia (BC) is in need of additional timber supplies. Hybrid poplar trees are fast growing and are widely dispersed in North America. The climate in the southern interior of BC offers the potential for high yields of hybrid poplar. One of the major concerns with hybrid poplar is adequate soil fertility, cold hardiness and high water needs. In semi-arid regions, hybrid poplar might be viable if planted within flood plains because the shallow groundwater may be accessible to the trees. However, the spatial variability of soils in stream/river flood plains can be highly variable. To select the correct hybrid poplar clones, the differences in soil fertility within a flood plain should be known. Therefore, if hybrid poplar is to become a viable fiber source in BC's semi-arid regions, we must understand what level of spatial variability exists within floodplains located within semi-arid areas. This project will be a collaboration between Thompson Rivers University and SK7ain Ventures Ltd. SK7ain Ventures Ltd. is a collaboration between Norbord Inc., a wood product company and the Skeetchestn Indian Band. The potential site is located on Skeetchestn land (flood plain of the Deadman River, BC). Norboard Inc. has agreed to purchase the wood when harvested. However, for this partnership to become a reality, research is needed to determine the feasibility of successfully planting and harvesting hybrid poplar on semi-arid lands. The study objectives are to: a. Determine the soil variability and fertility of soils located within the floodplain of the Deadman River, BC. b. Match the best hybrid poplar clones to the soil and climate of the region. c. Establish a long-term research collaboration between the Thompson Rivers University (TRU), the Skeetchestn Indian Band and Nordbord Inc.
