Long-term human environmental impacts in a cross-scale context across the Pacific Coast of North America

了解当前和未来的森林生态系统需要详细了解人类对环境的长期影响。在评估看似“野生”或“原始”的景观时，很少考虑这些长期的人类环境影响。然而，不考虑人的影响可能会大大低估或高估这些系统的弹性。我的研究项目的总体目标是量化和挑战人类与退化景观相关的范式。更具体地说，在接下来的五年里，我将：a)生成一个时间序列，说明人类影响何时从居住地点（人们居住的地方，导致物质记录的积累）移除；B)量化长期人类环境影响的空间范围和持续时间及其对森林组成和生产力的影响；C)预测未来居住地点的森林组成和生产力的增长；d)通过确定进入陆地环境的养分补贴量、人为火灾历史和森林生产力的相关变化，量化北美西北海岸的碳动态。***这项研究将继续与Heiltsuk和Wuikinuxv第一民族传统领土上的土著和非土著社区建立牢固的伙伴关系，这对这项工作的成功至关重要。该研究挑战了人类通过向陆地环境调节海洋养分补贴来驱动森林生产力模式的现有群落生态学范式，对进化和生态学领域具有重要意义。长期人类住区对景观有害的观念在我们对可持续性和环境问题的思考中根深蒂固。这个作品挑战了这种观念。这些结果将为沿海第一民族提供重要信息，提供详细的居住地点被遗弃的时间序列，并提供有关这些森林未来生产力组成的数据。通过在整个数据收集和推广阶段增加土著居民的参与，特别是与青年的参与，我的团队的研究的影响将得到加强。

Understanding current and future forest ecosystems requires detailed knowledge of long-term human environmental impacts. These long-term human environmental impacts are rarely considered when evaluating seemingly ‘wild' or ‘pristine' landscapes. However, failing to consider the influence of people may greatly under or over-estimate the resilience of these systems. The overall objective of my research program is to quantify and challenge held paradigms of humans being associated with degraded landscapes. More specifically, in the next five years I will: a) generate a time series of when human influence was removed from habitation sites (places where people lived resulting in the accumulation of a physical-material record); b) quantify the spatial extent and persistence of long-term human environmental impacts and their effect on forest composition and productivity; c) predict the future forest composition and productivity growing on habitation sites; and d) quantify carbon dynamics across the Northwestern coast of North America by determining the amount of nutrient subsidies moved into the terrestrial environment, the anthropogenic fire history, and the associated changes in forest productivity.*** This research will continue developing strong partnerships with Indigenous and non-Indigenous communities in the traditional territories of the Heiltsuk and Wuikinuxv First Nations that are critical to the success of this work. This work is of great significance to the field of evolution and ecology, as it is challenging existing community ecology paradigms about the role that humans play in driving patterns of forest productivity by mediating marine nutrient subsidies into terrestrial environments. This notion of long-term human settlement being detrimental to the landscape is entrenched in our thinking about issues of sustainability and environmental issues. This works challenges that notion. These results will contribute important information for the Coastal First Nations with a detailed time series of when habitation sites were abandoned and provide data on the future composition of productivity of these forests. The impact of my team's research will be enhanced by increasing Indigenous engagement, especially with youth, throughout the data collection and outreach stages.
