Crossing scales and disciplines to identify global trends in tree mortality
Crossing scales and disciplines to identify global trends in tree mortality as indicator of forest health
Globally, forests provide life-sustaining services such as storing carbon, hosting biodiversity, and regulating climate. Locally, human welfare relies on a stable provision of forest resources for energy, building materials, and food. Yet, this service and resource provision may be compromised as recent observations document instances of widespread tree mortality in all forested biomes. However, the lack of reliable global forest assessments precludes conclusions on a current threat of the world’s forests and on their fate under rapidly changing environmental conditions.
Existing monitoring approaches are either incomplete or use data with inadequate resolution for detecting individual tree mortality. Such data exist but are spread across many different depositories and disciplines (field monitoring networks, forest inventories, remote sensing). A common and openly accessible depository would facilitate a horizontal (intradisciplinary) and vertical (interdisciplinary, across spatial scales) information transfer and the rapid detection and interpretation of changes in forest condition and future development of global forest ecosystems.
Background and Objective
Workshop report:
This workshop aims to bring together different disciplines and data depositories. Attendees will meet in plenary sessions to discuss best approaches for data integration and interpretation to develop a global monitoring network. Smaller break-out group meetings, both intra- and interdisciplinary, will provide platforms for developing action plans on how to combine, manage, and redistribute data. Further data requirements will be discussed and new tools (a mortality app) will improve data acquisition and foster public awareness. Working groups will be responsible for (1) the publication of workshop results, (2) the coordination of funding proposals for initializing and maintaining the data depository and (3) the planning of future activities, including follow-up meetings. Both meetings and working groups will be led by young scientists allowing them to increase their visibility in the scientific community. Mentoring by established researchers will reinforce integration of young scientists and promote their future careers.
