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。杂种杨树正在快速生长，并且是 在北美广泛分散。卑诗省南部内部的气候提供了高潜力 杂种杨树的产量。杂种杨树的主要关注点之一是足够的土壤生育能力，寒冷的野性 和高水需求。在半干旱地区，如果种植在洪水泛滥的平原上，杂种杨树可能是可行的 树木可以接近浅地下水。但是，溪流/河中土壤的空间变异性 洪水平原可能是高度可变的。为了选择正确的混合杨树克隆，土壤肥力的差异 应该知道在洪水平原内。因此，如果杂种杨树成为卑诗省的可行纤维来源 半干旱地区，我们必须了解位于洪泛区内的空间可变性水平 半干旱地区。 该项目将是汤普森河大学和Sk7ain Ventures Ltd. SK7AIN之间的合作 Ventures Ltd.是木制产品公司Norbord Inc.与Skeetchestn Indian之间的合作 乐队。潜在地点位于Skeetchestn Land（不列颠哥伦比亚省Deadman River的洪水平原）。 Norboard Inc. 收获时已同意购买木材。但是，为了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集杂种杨的可行性。 研究目标是： 一个。确定位于卑诗省死人河洪泛区内的土壤变异性和生育能力。 b。将最佳的混合杨树克隆与该地区的土壤和气候相匹配。 c。建立汤普森河大学（TRU）之间的长期研究合作 Skeetchestn Indian Band and Nordbord Inc.
