NSERC Industrial Research Chair on Peatland Management - 3

加拿大泥炭行业认识到负责任的资源管理的重要性，该管理基于经过验证的环境、社会和经济利益的科学生态原则。然而，需要采取管理行动，以促进自然再殖民化或恢复生态系统。为了帮助商业泥炭地恢复泥炭堆积功能或开发一种可持续的生产泥炭生物量的方法，本教席计划将重点研究关键积累植物物种的生物学，以及如何促进它们重返加拿大不同地区退化的湿地生态系统。这将通过三个主题的研究来完成。首先，将与园艺或农业院校和乡土植物苗圃合作，对典型的乡土树种进行贮藏、分层和生长条件试验。在第二部分中，将完善退化泥炭生态系统沼泽物种的建立和便利化。文中将对林木林火后植物的定植和演替进行个案研究。开发的沼泽恢复方法将通过对苗木种类、种子就地播种、恢复过程中的石灰和施肥以及入侵植物防治的研究，使之适用于沼泽。还将研究植物材料在储存中的存活情况。最后，第三部分将重点研究泥炭藓主要物种的生态-水文关系(寻找与物种相互作用有关的最佳水位)，以及降低地毯底部的分解速率以增加泥炭泥养殖流域的生物积累。

The Canadian peat industry recognizes the importance of a responsible resource management based on proven scientific ecological principles for environmental, social and economic benefits. However, management actions are required to either facilitate natural recolonization or to restore the ecosystem. To assist the choice of intervention during the restoration of the peat accumulating functions in commercial peatlands or to develop a sustainable way to produce Sphagnum biomass, this Chair program will focus on the biology of key accumulating plant species and how to facilitate their return into the degraded wetland ecosystems across different Canadian regions. This will be done through three topics of research. First, in collaboration with horticulture or agriculture-oriented colleges and native plant nurseries, experiments concerning storage,stratification and growing conditions will be conducted on typical native fen species. In the second part, the establishment and facilitation of fen and bog species in degraded peat ecosystems will be improve. A case study on post-fire plant colonization and succession in a rich fen will be done. The method developed for bog restoration will be adapted to fens by doing research on nurse species, on in situ sowing of seeds, on liming and fertilization during restoration and on invasive plant control. The survival of plant material to storage will also be studied. Finally, the third part will focus on the eco-hydrological relationships (to find the optimal water level in relation with species interactions) ofkey Sphagnum species and on the reduction of the decomposition rates at the base of the carpet to increase biomas accumulation in Sphagnum farming basins .
