The Bonanza Creek (BNZ) LTER: Regional Consequences of Changing Climate-Disturbance Interactions for the Resilience of Alaska's Boreal Forest

Bonanza Creek(BNZ)LTER项目于1987年启动，自那时以来一直提供实验和观测研究，旨在了解阿拉斯加北部森林生态系统的动态、弹性和脆弱性。该项目阐明了北方森林生物和生态系统对气候和各种大气输入的反应，重点是森林和景观动态以及生物地球化学。该项目将继续这一长期研究方向，扩大其研究范围，扩大由此产生的信息的预测范围，并直接解决社会经济系统的复原力问题。该项目假设，过去观察到的北方生态系统对环境条件年际和年代际变化的高弹性正在接近一个关键的临界点。该项目有助于理解北方森林生态系统和包括人类社区在内的更广泛的北方景观的结构、功能和动态。它汇集和整合了关于气候、水文学、生物学、生态学、生物地球化学和地貌过程的有价值的长期数据集，并纳入了新出现的数据类型，包括分子和社会科学数据以及数字图像。该项目对知识的贡献具有广泛的社会价值，这些知识可以为北方森林生态系统的管理和维持生计的社区的可持续性提供信息。其更广泛的价值还包括广泛的基于研究的培训和教育项目开发。其强大的公众推广计划包括艺术家和科学家之间的合作以及与土著组织的密切联系。

The Bonanza Creek (BNZ) LTER project was initiated in 1987 and since then has provided experimental and observational research designed to understand the dynamics, resilience, and vulnerability of Alaska's boreal forest ecosystems. The project has illuminated the responses of boreal forest organisms and ecosystems to climate and various atmospheric inputs, focusing on forest and landscape dynamics and biogeochemistry. This project will continue that long-term line of research, expanding it to broaden the landscape under study, broaden the predictive realm of the resulting information, and to directly address the resilience of socio-economic systems. The project hypothesizes that the past observed high resilience of boreal ecosystems to interannual and decadal changes in environmental conditions is approaching a critical tipping point. This project contributes to understanding of the structure, function, and dynamics of boreal forest ecosystems and the broader boreal landscape, including the human communities. It assembles and integrates valuable long-term data sets on climate, hydrology, biology, ecology, and biogeochemical and geomorphic processes, as incorporates emerging data types, including molecular and social science data and digital images. The project has broad societal value through its contributions to knowledge that can inform management of boreal forest ecosystems and sustainability of subsistence communities. Its broader values also include extensive research-based training and educational program development. Its strong public outreach program includes collaborations between artists and scientists and strong linkages with Native organizations.
