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

D.T1.1.1 ALPTREES Report on Database with Inventory

This study in Working Package WPT-1 aimed to perform an inventory of non-native tree species growing in Alpine Space forests and cities, analyzing their diversity, distribution, and geographic origin.
Our results show that at least 526 NNT are currently growing in forests and urban areas in the Alpine Space. The number of NNT growing in urban areas (352) is much higher compared to woodlands (13), yet a considerable large number were reported for both urban areas and forests (161). These figures clearly show that a large proportion (67%) of reported NNT are currently being cultivated exclusively in cities in the Alpine Space. Of these, the most common NNT are Aesculus hippocastanum (horse chestnut), Robinia pseudoacacia (black locust), and Gleditsia triacanthos (honey locust).
Most of the reported NNT (90%) have their natural distribution range outside of the European geographical area. The largest number of these species were introduced from Asia (248) followed by North America (180).
About 5% of reported NNT have been considered (potentially) invasive in one or several regions of the Alpine Space. Most of them have their native distribution range in North America.
NNT are widely used in the Alpine region for landscaping and horticultural purposes (35%). Other frequently mentioned benefits include their use as an ornamental tree or their potential to sequester carbon.

D.T.4.1.1 Stakeholder Analysis Report

In Central Europe, discussion in forest management has increasingly focused on how humans can assist these adaptation /migration processes, especially when important forest ecosystem services are at risk. One option is to introduce non-native tree species to help forest ecosystems adapt to climate change (Frischbier et al. 2019) Non-native tree species can support the adaptation of European forests and urban areas to climate change, but simultaneously entail risks for biodiversity and ecosystem functions. Many efforts have already been undertaken to manage these risks, but neither European or national/regional recommendations and strategies for non-native tree species management exist in the Alpine Space that consider the challenges of climate change yet. The European Alpine Space has important potentials for dynamic development, but is facing major challenges at various levels including the pan-Alpine, regional and local levels as well as in cross-border areas. These challenges refer for instance to the specific geographical position, globalization, demographic trends, climate change and its impact on the environment, biodiversity, territorial pattern of activities and living conditions.

D.T1.2.1 ALPTREES Field Survey

The status of semi-natural oak-hornbeam forests (European Union habitat type 9160) is classified as unfavorable in several regions across the Alpine Space (AS). This habitat type is considered threatened by invasive non-native species including several non-native tree species (NNT). In the lowlands of AS in south-west Germany, dispersal of the NNT red oak (Quercus rubra L.) has been reported in several protected forest habitats, located in the habitat type 9160 (FFH9160).

The Usage Value of Non Native Trees - Alptrees Timber Report

Although NNT products are already widely used in Europe, they have not received attention in the New EU Forestry Strategy agenda. Accordingly, the ALPTREES project has the merit of promoting the added value of NNTs for Europe´s forests and related value chains. The authors also open the debate on the existing and potential markets of NNT assortments and create more confidence in their current and future use. The document can be seen as a first attempt to raise awareness among customers and decision makers about the use of NNT wood. In a compact format, the report summarizes the practical scientific findings on the most important NNT species for the timber market. The report also provides a preliminary outlook on the economic value of NNTs wood products along the timber value chains of some Alpine countries. Furthermore, it illustrates in a simple and intuitive way some valuable experiences made by companies active in the Alpine Space.

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

https://youtu.be/C7NlwShnKc8

Urban trees, especially on private properties are usually not monitored. A citizen science activity supports the collection of data on urban and forest trees, raise awareness among the general public regarding the question of alien and native trees; This activity establishs a framework and information system for early detection and rapid response (EWRR) to alien species, improves capacity to manage the EWRR by mobilizing and training both professionals and volunteers. We selected the iNaturalist App, which gives the advantage to be part of a larger initiative. The App will be integrated is a specifically skilled “serious game” for a crowdsourcing campaign for the online App, which includes a public user survey to identify the links between ecosystem services and public perception. Experts and public alike were invited to join the ALPTREES iNaturalist “Train the Trainer” Webinar on Thursday, 22nd of April 2021. iNaturalist is a citizen science mobile application and also available as a platform for web, to explore nature and contribute to scientific data collections to monitor ecological challenges. This webinar was all about the handling of the App and how to engage people of different ages to participate in activity, which is educational, scientific, practical, and outdoor. The particular focus of the ALPTREES project is to improve knowledge-based decision-making on the responsible use and management of non-native tree species in the Alpine Space.

D.T4.1.5 French Stakeholder Workshop with national representatives

Invitation to the ALPTREES French Stakeholder Webinar on 3rd of February 2021. We are pleased to invite you to our ALPTREES French Stakeholder Webinar on the Sustainable Use and Management of Non-Native Trees in Urban, Peri-Urban and Forest Ecosystems in the Alpine Region, organized by Cerema and INRAe. The meeting will be held in French language.

The overall objective of ALPTREES is to improve knowledge-based decision-making on the responsible use and management of non-native tree (NNT) in the Alpine Space by developing a transnational strategy on NNT. We are inviting participants to share their work and knowledge on non-native trees in forests as well as in urban areas and to participate in this participative process within the network of stakeholders of the Webinar.
