Sustainable use and management of non native trees in the alpine region

Activity A.T2.1 Future Forest Projections with particular emphasis on NNT

D.T2.1.1 Risk maps set

Maps displaying different future climate pathways and their impacts on natural forest as well as NNT. These maps will consider inter alia forest management, climate change risks and opportunities, and environmental protection parameters.The IIASA-led ALPTREES Work Package WPT2 developed risk maps based on Climate Change (CC) prediction models (see example for precipitation in Fig. 1), with special emphasis on the forest area, urban forests, the peri-urban interface, and urban trees. Respective deliverables are highly relevant for support tools for CC adapted decision making in the public and private space.


D.T2.1.2 Recommendation Report

Interpretation of mapped results​: The AS-wide scenarios include different types of managed and unmanaged forest area, sustainability aspects such as certified forest management, specific environmental habitat conservation, and other protection types.


Activity A.T2.2 Citizen Science on Trees in the City & Forests

D.T.2.2.1 ALPTREES App

Urban trees, especially on private properties are usually not monitored. A citizen science activity will support  the  collection  of  data  on  urban  and  forest  trees,  raise  awareness  among  the  general  public  regarding  the  question  of  alien  and  native  trees;  The ALPTREES platform on the App inaturalist will establish  a  framework  and  information  system  for  early detection and rapid response to alien species, improve capacity to manage by mobilizing and training both professionals and volunteers. The App is feasible for public users survey to identify the links between ecosystem services and public perception.


D.T.2.2.2 Crowdsourcing campaign result report

Crowdsourcing campaign enabled additional information (complementary to the traditional sources, like national forest inventory and urban tree cadasters) on non-native tree species distribution in the Alpine region and raise awareness among attendees about the issues and opportunities associated with NNTs. We initiated an ALPTREES project within platform, promoted crowdsourcing campaign in social networks, media, at ALPTREES scientific conference and at the Train the Trainer Workshop.


Activity A.T2.3 Urban NNT assessment

D.T2.3.1 Report on Urban NNT assessment in the Alpine Space

Urban trees are more vulnerable to climatic change due to more extreme climatic environment, necessitating adaptive measures in tree selection, which increasingly makes non-native trees potentially suitable candidates for urban applications in the future. With this report we aim to fill some knowledge gaps by assessing non-native urban tree species drought tolerance to provide technical recommendations for urban and peri-urban green infrastructure. The results of this activity will support the data modeling activity, as well as recommendations for growing non-native tree species (NNT) in urban areas.


D.T2.3.2 Recommendation report for future NNT policies in the urban and peri-urban space

Future options for NNT in the urban and peri-urban space will be assessed and delivered in the Policy recommendation for NNT in the urban and peri-urban space, which will be formulated and discussed with all PPs and experts as well as stakeholders.


Activity A.T2.4 Web GIS and the inter-active online decision

The Web GIS tool will be implemented in the Open ALPTREES Knowledge Hub.

D.T2.4.1 Interactive Web GIS application

This report on the interactive ALPTREES Web GIS primarily serves as the proof of development and delivery of the respective tool and to provide relevant links for accessing the tool. The ALPTREES Web GIS tool has been implemented as a Google Earth Engine App (see: within the Open ALPTREES Knowledge Hub as an output of the ALPTREES Work Package WP 3 to share policies, tools, and technical guidance for the management and responsible use of NNT. This inter-active tool will allow stakeholders from different sectors to distinguish between positive and negative impacts of NNT and to see the predicted impact of CC in any location of the AS. The Web GIS tool will be open to and used by citizens, NGOs, public authorities, education bodies, and businesses or even investors. For this ALPTREES Web GIS tool on Google Earth Engine, all 168 tree species suitability maps/risk maps - as described in the ALPTREES Deliverables DT2.1.1 Risk Maps Set, and DT2.1.2 Recommendation Report – have been incorporated. Furthermore, four additional information layers/set of maps have been developed in order to improve the information provided to the App user and to support respective decision making.
