Dear Colleagues,
Henrik Hartmann and others are seeking input and information about tree mortality data sources globally. Below you will find more information about the International Tree Mortality Network, the IUFRO Task Force, and links to surveys where
you can provide a description (meta-data) of remotely sensed or ground data that could be added to the network. The surveys will remain open through this month.
Best,
Barbara Bentz

Dear colleague,
You receive this mail because you have been involved in former activities of the
International Tree Mortality Network or are involved in forest monitoring approaches. We are seeking your help to assemble information on existing field data sources across the world that allow deriving tree mortality rates.
Who are we and what is our mission? The International Tree Mortality Network (https://www.tree-mortality.net/)
has been established as an initiative of the International Union of Forest Research Organizations (IUFRO)
Task Force on monitoring tree mortality trends and patterns (https://www.iufro.org/science/task-forces/tree-mortality-patterns/).
Our mission is to facilitate collaboration between scientists to combine expertise, knowledge and data, thereby allowing a global assessment of tree mortality and providing crucial information for scientists, forest managers and policy making.
Quantitative information on tree mortality at the global scale is limited and different protocols of field data collection make inter-comparison challenging. The International Tree Mortality Network seeks to
assemble meta-information on existing field assessments to develop methods for quantification of tree mortality rates. This information will be made freely available to the community. The ultimate goal of this activity is to
develop standardised post-collection processing methods that can be used to calculate consistent and comparable mortality metrics from different network protocols and measurement platforms across the globe, and to
make these methods and metrics available to the scientific community. This is envisaged as a community activity linking existing networks and research groups, it does not seek to collect raw data.
The links below will take you to two surveys, specifically designed to be as brief as possible. The surveys seek to assemble metadata on existing field assessments (i) to develop methods for quantification of tree mortality rates consistently across different
protocols, and (ii) to link ground and satellite-based information to understand how tree mortality changes over time. Please follow the appropriate link according to whether you collect terrestrial (e.g. plot) or remote-sensing data.

We would be delighted if you would also like to become actively involved in the activities of the IUFRO task force and the tree mortality network. In this case please contact us via our websites above.
Best wishes,
The ITMN core team
