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.

不列颠哥伦比亚省 (BC) 需要额外的木材供应。杂交杨树生长速度快， 广泛分布于北美。 BC 省南部内陆地区的气候提供了高温的潜力 杂交杨的产量。杂交杨树的主要问题之一是足够的土壤肥力、耐寒性 和高水需求。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 树木可以接触到浅层地下水。然而，溪流/河流中土壤的空间变异性 洪泛区变化很大。要选择正确的杂交杨无性系，土壤肥力的差异 应该知道洪泛平原内的情况。因此，如果杂交杨树要成为 BC 省可行的纤维来源 在半干旱地区，我们必须了解位于其内的洪泛区存在什么程度的空间变异性 半干旱地区。 该项目将由汤普森河大学和 SK7ain Ventures Ltd. 合作。 SK7ain Ventures Ltd. 是一家木制品公司 Norbord Inc. 与 Skeetchestn Indian 的合作项目 乐队。潜在地点位于 Sketchestn 土地（不列颠哥伦比亚省戴德曼河的洪泛平原）。诺博德公司 已同意在采伐后购买木材。然而，为了使这种伙伴关系成为现实，需要进行研究 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。 研究目标是： 一个。确定不列颠哥伦比亚省戴德曼河漫滩内土壤的变异性和肥力。 b.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.汤普森河大学 (TRU)、 Sketchestn Indian Band 和 Nordbord Inc.
