REINFFORCE main aimBuild a research tool to meet the climate

change challenges.

❖Better knowledge of tree species

performance response to future climate

scenarios, improving uncertainty;

❖Test effectiveness of adaptive forest

management;

❖Accompanying Scientific cooperation on

climate change adaptation

REINFFORCE infrastructureTake advantage of the Atlantic network of IEFC and

EFIATLANTIC partners ->compare sites from

longitudes 37 to 57º, under a strongly oceanic

influenced climate

❖12 partner Institutions

❖Arboreta network (38 sites),

❖Demonstration site network (41sites),

❖Common protocols (growth

measurements, phenology, health, etc.).

The arboreta networkAim: expose the same genetic material produced in the same

conditions to various climate/soil contexts.

❖Each of the 38 arboretum is about 2 hectares with 2000

trees;

❖35 species ; 3 provenances/species; 12 trees/ provenance.

❖Arboreta sites represent typical site conditions for managed

forests in each region, with Weather monitoring

❖Sites will be monitored for at least 15 years with

standardized methods.

Key messages

❖ A strategical tool for forest adaptation to climate change;

❖key parameters for growth and survival: Transfer Distance for Precipitation, Annual

Dryness Index, Growing Season Degree Days >5⁰C

❖Broadleaf survival at installation (first years) will not present significant loss under

moderate RCP scenario;

❖ Conifer survival will vary accordingly to each Species, yet there is associated risk

even for moderate RCP scenario for mid term projection;

❖ Global risk for growth loss, except for Eucalyptus globulus and gundal.

Building an Interface for knowledge application

In order to facilitate the dissemination of the fitted models and predictions, a mobile

app is being built, focusing on:

❖risk calculation per species

❖Growth and survival estimation under RCP 4.5 and 8.5, for 2050 and 2080

❖Suggestion of the species presenting best results

❖Species characterisation and silviculture information
