NEWSLETTER
Dear members,
The International Tree Mortality Network is now up and running!
We will organize different activities during the upcoming months and years and will use our <http://x6hr8.mjt.lu/lnk/AUgAAARkFs8AAchR_j4AALV5HxgAAYCsMcgAnDSWABQMVQBe7dR…> webpage and regular distribution of newsletters to keep you informed and to get you involved. Despite the fact that the current health situation has jeopardized our first scientific activity, a workshop on harmonizing data on forest condition that was scheduled for late March but was cancelled, we have succeeded in taking up additional momentum.
Please read on, this is the start of a global initiative that will propel science, forest management and policy making!
Data surveys of global forest condition
We recently have launched two surveys on data availability of global forest condition. The surveys seeks 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. We have already received XX responses from contributors around the globe. Please press the buttons to fill out the surveys.

<https://x6hr8.mjt.lu/tplimg/x6hr8/b/xr37r/gl6tl.png>
Participants of the surveys and other experts will be given the opportunity to contribute to topical online working groups. Invitations will be sent out this summer. We'll keep you updated.

To increase awareness about climate change-induced tree mortality as a global phenomenon, we want to host images on mortality events on our <http://x6hr8.mjt.lu/lnk/AUgAAARkFs8AAchR_j4AALV5HxgAAYCsMcgAnDSWABQMVQBe7dR…> webpages. To do so, we seek your support, please send us images of mortality events (large group of trees, forest stands,...) to <mailto:treemortnet@gmail.com> treemortnet(a)gmail.com, and add a short description about the main species affected, the region and country, the cause (e.g., bark beetle) and year of mortality (if known), and the name of the copyright holder (for example, Spruce_Thuringia_Germany_bark beetles_2019_Hartmann.jpg).

Global database and interactive map of tree mortality events
We have posted a tree mortality event map on our <http://x6hr8.mjt.lu/lnk/AUgAAARkFs8AAchR_j4AALV5HxgAAYCsMcgAnDSWABQMVQBe7dR…> webpage. For the time being, the map is a geo-referenced version of the "Allen mortality map" (Allen et al. 2010, Hartmann et al. 2018) and is currently populated by Bill Hammond as part of his PhD dissertation. Once published, we will post on our <http://x6hr8.mjt.lu/lnk/AUgAAARkFs8AAchR_j4AALV5HxgAAYCsMcgAnDSWABQMVQBe7dR…> webpage not only the interactive map that provides geo-referenced information on tree mortality events documented in peer reviewed publications over the last ~50 years, but we will also add a functionality allowing the signalling of new mortality events via an online entry tool.

Events taken from Allen et al. 2010, IPCC 2014, Allen et al. 2015, Hartmann et al. 2018, Hammond et al. in preparation. The map currently is being populated with ~1000 precisely georeferenced research plots that document these mortality events by William Hammond. Tree height data are from Simard et al., 2011.

Dear colleagues,
Due to the current health situation we, the IUFRO Task Force on Monitoring
Global Tree Mortality Patterns and Trends, had to cancel our first workshop
on Harmonizing terrestrial data sources on forest condition that was
supposed to be held in Wuerzburg, Germany, at the end of March. We have
acted upon the corona restrictions and have substituted the 'physical'
workshop with two online surveys, which will be followed by a series of
virtual working group meetings.
Surveys and workshops aim to identify existing terrestrial and remote
sensing data sources on forest condition and how the data can be harmonized
to infer information on tree mortality rates and trends over time. We now
seek your help to assemble information on existing data sources that allow
deriving global tree mortality rates. The links below will take you to the
surveys, specifically designed to be as brief as possible. The surveys seek
to assemble metadata on existing data sources in order to:
· develop methods for quantification of tree mortality rates
consistently across different protocols, and
· link ground and satellite-based information to understand how tree
mortality changes over time.

Data hosting will be assumed by the International Tree Mortality Network (
<https://www.tree-mortality.net/> https://www.tree-mortality.net/) which is
an initiative established by the IUFRO Task Force on Monitoring Global Tree
Mortality Patterns and Trends.
Please contact us (

youre interested in joining the post-survey workshops or for any other
requests or inquiries.

Dear all,
WSL (the Swiss Federal Institute for Forest, Snow and Landscape Research) is advertising a post-doctoral position on the ecology of biological invasions, a collaborative project with eawag (the Swiss Federal Institute of Aquatic Science and Technology). The aim of the project is to compare invasions in aquatic and terrestrial ecosystems primarily at large (national) spatial scales and among several higher-level taxa (insects, molluscs, crustaceans, all major vertebrate classes, and plants), test the biotic resistance hypothesis, and explore the role of factors that could influence invasiveness and invasibility.

Dear colleagues,
We hope you and your families, colleagues, and friends remain in good
health.
Due to the Covid-19 pandemic and ongoing uncertainties on international
travel, the organizing committee of the NFZ 2020 Summer School “Emerging
pests and diseases in temperate forests” decided to postpone this event
to July 5-9, 2021.
Please check our website (https://workshop.inrae.fr/nfz-summerschool/ )
where any relevant announcements will be published.
Take care of yourself.
Best regards,
Pascal Frey, Benoit Marçais, Christelle Robinet and Valentin Queloz
