Forestry is an economically important industry on Vancouver Island that supports thousands of families.Modern logging practices seek to minimize environmental impacts; however, terrestrial and marine habitatdegradation from logging remains a challenge in British Columbia (BC). Habitat banks are an important toolused by the forestry sector to compensate for these environmental impacts. In this project, NSERC will supportNorth Island College (NIC) and M.C. Wright and Associates (MCWA), in collaboration with BC Timber Sales(BCTS), to develop an innovative type of habitat bank for the forestry sector - planted kelp beds. Kelp naturallyprovides food and habitat for many different species while improving water quality, and thus holds significantpotential to rehabilitate degraded marine habitat. Building on the work completed in an NSERC Engageproject, this ARD project will test the efficacy of three different kelp planting techniques at sites aroundVancouver Island and the adjacent BC mainland: 1) horizontal longlines, common in the kelp aquacultureindustry; 2) vertical drop lines, which may also act as a debris curtain; and 3) seeded rock that is out-planted onthe ocean floor, a technique that was recently developed in Norway. Three kelp species will be trialed, all ofwhich are commercially valuable and indigenous to British Columbia, and their productivity will be comparedto unplanted (naturally seeded) controls. Site conditions will be assessed through dive surveys and data loggers.This project will provide practical insights for kelp habitat bank development in terms of planting techniques,kelp species, and site conditions that were successful or unsuccessful. Results will be immediatelyimplemented by the industry partners and possibly other forestry companies to build new kelp habitat banksalong the coast.

林业是温哥华岛上一个重要的经济产业，为成千上万的家庭提供支持。现代伐木做法试图将环境影响降至最低;然而，伐木造成的陆地和海洋栖息地退化仍然是不列颠哥伦比亚省（BC）面临的一个挑战。生境银行是林业部门用来补偿这些环境影响的一个重要工具。在这个项目中，NSERC将支持北岛学院（NIC）和M.C. Wright and Associates（MCWA）与BC Timber Sales（BCTS）合作，为林业部门开发一种创新型的栖息地银行-种植海带床。海带天然地为许多不同的物种提供食物和栖息地，同时改善水质，因此具有恢复退化海洋栖息地的巨大潜力。在NSERC Engageproject完成的工作的基础上，该ARD项目将在温哥华岛和邻近的BC大陆附近测试三种不同海带种植技术的效果：1）水平延绳钓，常见于海带水产养殖业; 2）垂直下降线，也可以作为碎片帘;和3）将种子岩石外植到海底，这是挪威最近开发的一项技术。三种海带将被试验，所有这些都是有商业价值的和本土的不列颠哥伦比亚省，和他们的生产力将比较unplanted（自然播种）控制。通过潜水调查和数据记录器对现场条件进行评估。该项目将从种植技术、海带品种和现场条件的成功或不成功方面为海带栖息地库的开发提供实用的见解。研究结果将立即由行业合作伙伴和可能的其他林业公司实施，以在沿海地区建立新的海带栖息地。
