D.C.2.2 Handbooks - Identification Handbooks for non native trees in the Alpine Space

In this pocket guide, we describe 49 non-native tree species (NNT), selected from more than 530 NNT that occur in forests, peri-urban and urban areas in the Alpine Space. We selected these NNT because they are widely distributed in the countries of the Alpine Space (i.e. Austria, Italy, Slovenia, France, Switzerland and Germany) and appear useful for climate change adaptation due to their species-specific characteristics. Some of these species were selected because they may have the potential to be or become colonising character. Each tree species is presented on four pages with a brief general description, a drawing, and photographs of the characteristic and morphological species features. In addition, various symbols and icons are used throughout the brochure for each species to represent their potential invasiveness, ecological requirements, and degree of allergic potential. 

Identification Hand Books


D.C.2.2 Handbooks - ALPTREES Handbook for Management of non-native tree species IN FORESTS of the Alpine space

In ten chapters this Handbook provides results and scientific approaches of our partners about the situation of non native tree species in Alpine Forest areas.
Selected non native tree species that were already introduced in the Identification Handbook 1 find additional indepht information about legislative frameworks as well as expert's opinions.


D.C.2.2 Handbooks - ALPTREES Handbook for Management of non-native tree species IN URBAN AREA of the Alpine space

Urbanized areas act as heat islands that experience higher temperatures than their surroundings. Man-made structures, including buildings and roads absorb and re-emit the sun’s heat more than natural landscapes such as forests and bodies of water. For this reason, trees and urban forests are essential in  built-up areas: They provide numerous ecosystem ervices and make our lives easier and more pleasant. With its 14 chapters, This handbook provides the latest scientific facts and knowledge about the use and management of non native tree species in Urban Space.

D.C.4.5 Podcasts

Episode 1 – Non Native Tree Species and the Future of the Alpine Space
The role of non native trees species in the Alpine Space The ALPTREES podcast series answer the questions of citizens of all ages and educational levels and give insight into our scientific work to build a transnational guideline for the use and management of non native tree species in the Alpine Space. From the basics "what is a non native tree species" to specific topics like "women in forestry", each podcast has it's thematic focus.

Project leader Katharina Lapin gives an introduction to the obstacles of the ALPTREES project.

Episode 2 – Between steep Slopes and the Beach
The topic of non native tree species in the French Alps are discussed by experts from Grenoble and Aix en Provence, describing the situation of forests in cities, in the mountains and in the mediterranean area. The ALPTREES podcast series answer the questions of citizens of all ages and educational levels and give insight into our scientific work to build a transnational guideline for the use and management of non native tree species in the Alpine Space. The situation of non native tree species in forests and cities in the french Alps are discussed by Patricia Detry from Cerema in Aix en Provence and Frederik Berger from INRAE in Grenoble.

Episode 3 – IIASA, Making the Future visible - Scenarios for our Trees
How can we look into the future of tree species in forests and cities? What actions will be fruitful for the adaption of forests under unknown various parameters? Can non native trees help tree populations in cities and forests to adapt to climate change? Our partners from IIASA in Laxenburg/Vienna, talk about "time travels" to the future with computer models, different future climate scenarios and the tricky obstacle on how to interpret data.

Episode 4 – Timber of non native trees and the ALPTREES Timber Survey
Martin Braun from BOKU and Camila Maciel Viana, Master student at BOKU evaluate the timber market for non native tree species in the Alpine Space. From sawmills to the timber production industry, from artists to craftsmen of music instruments. About success and failures, quality management, experiences, price strategies with non native tree timber.

Episode 5 – Citizen Science - Involving the public's eyes in generating Data
How many non native tree species can be found in the Alpine region - Is the number increasing? And who observes and counts the samples of one tree species? Who counts sightings of pest insects and signs of diseases in forests that can threaten tree populations and local biodiversity? Only foresters, scientists and experts? To project the future of plants and animal wildlife is one of the subjects of nature sciences. To gather this kind of data via observing, counting, collecting, comparing and interpreting can also be part of every non scientists life. Citizens are invited to take part in observing and collecting data in various Apps like for example the inaturalist App.

Episode 6 – Sharing the Knowledge about Non Native Tree Species
In the ALPTREES project, our pilot actions and publications, TREE TALKs and Workshops were organized to transfer collected data and knowledge about NNTs to experts, stakeholders and the general public. In this podcast our partners reflect on their successes and challenges on communicating with adults as well as developing training material for young audiences.

Episode 7 – The Strategy on non native trees in the Alpine Space
After 22 month of working on the “ALPTREES Strategy on the use and management of non native tree species in the Alpine Space”, the ALPTREES team reflects on the work, the progress, the successes and the challenges we all faced in our various workpackages to meet the core goal of the project: To provide policymakers, stakeholders, political decisionmakers and the general public with a guideline on how to deal with non native tree species throughout the Alpine Space in Slovenia, Italy, France, Austria and Germany.

Episode 8 – Stress in the City
For trees to be able to provide ecosystem services in cities, trees have to be respected as living creatures and not treated as decoration for parking lots. Hot temperatures, drought, air pollution, noise, light pollution and isolation take a toll on health and wellbeing of all species under extreme circumstances.

Episode 9 – Site specific risk assessment
„Risk assessment” can be defined as the standard evaluation of (potential) negative impacts associated with the introduction, establishment, and spread of nonnative tree species. We developed a new methodological framework of a “site-specific risk assessment”. In comparison to already existing methods, our method is based on a stratified assessment of risks posed by non native tree species that distinguishes between different ecosystem types or sites. The assessment method therefore enables to consider the regional context as well as the effectiveness of available management strategies to mitigate negative effects in the area of interest. It serves as a decision support system for the selection of sites, non native tree species and silvicultural methods for limiting potentially associated risks, while taking advantage of the ecosystem services of potentially beneficial NNT.

Episode 10 – Lessons learnt from the Pilot Actions
What is a pilot action, how were the Pilot Actions within the ALPTREES project planned and conducted - and what are the lessons learnt from these hands-on projects, that displayed the role of non native trees in urban space, forests and in the awareness of the public.

Episode 11 – Situation of non native tree species in Switzerland

One of Switzerland’s most influential Forest Experts Peter Brang gives an insight into the situation of non native tree species in Switzerland and Liechtenstein.

Episode 12 – Tree Migration from South to North – the role of Human activity and Climate Change
Native and non-native tree species witness the tendency to migrate within the Alpine Space from South to North. Is this migration human driven or due to climate change?
The talk with experts from the field of biodiversity, climate change, tree genetics and forestry.
