Field visits


During the second day of the symposium (November the 20th 2019), 40 researchers and project holders from everywhere in Europe six countries had the opportunity to discover the Haut-Languedoc Regional Nature Park which sits in a unique area of meeting point for three climates (Mediterranean, Atlantic, Alpine), and is thus in a place where the environment will be very sensitive to any shifting of climate ranges. Two third of this territory is also covered with forests, hence making it a perfect location to talk about forest adaptation to climate change.

The field visit included a visit of three FORECCAsT trial stands, where the project tests tree species and forest management procedures adapted to climate change, as well as the demonstration of three field decision-making tools:

  • Analog Forestry (demonstrator: John KAGANGA)
  • FORECCAsT by BioClimSol (demonstrator: Maxime JOURDE)
  • TerrHum (demonstrator: Augusto ZANELLA)

You will find below more details about the test sites and the decision-making tools.

“Donadille” spruce and fir forest stand

There are two species planted in this forest stand: some silver fir in the western part and some European spruce in the eastern part. The challenge here was to mitigate climate change risks by promoting the natural regeneration as well as adding a third tree species, in case of dieback on the two already there. To do so, we opened several gaps in this forest, and we planted in some of them several plants of Atlas cedars.

“Le Treilhat” arboretum

In this arboretum, we are testing 21 genetic units (species or origins), among which Mediterranean pines, oaks and firs that we think could be better adapted to the climate to come.

  • Firs: Abies alba (Silver fir), Abies bornmuelleriana (Turkish fir), Abies cephalonica (Greek fir), Abies nordmanniana (Nordmann fir), Pseudotsuga menziesii (Douglas fir, Luzette and California origins)
  • Cedars: Cedrus atlantica (Atlas cedar), Cedrus libani (Lebanon cedar)
  • Beeches: Fagus orientalis (Oriental beech), Fagus sylvatica (European beech)
  • Pines: Pinus laricio corsicana (Corsican pine), Pinus nigra salzmanii (Pyreneean pine), Pinus pinaster (Maritime pine)
  • Oaks: Quercus canariensis (Algerian oak), Quercus cerris (Turkey oak), Quercus faginea (Portuguese oak), Quercus petraea (Sessile oak), Quercus pubescens (Downy oak)
  • Other: Castanea sativa (Sweet chestnut), Celtis australis (European nettle tree), Robinia pseudoacacia (Black locust)

“La Frucharié” mixed-forest plantation

In 2019, we tested in this stand located at 740m high a plantation mixing three species:

  • The Pyreneean pine Pinus nigra salzmanii
  • The Oriental beech Fagus orientalis
  • The Turkish fir Abies bornmuelleriana

Demonstration of decision making tools

Analog Forestry (demonstrator: John KAGANGA)

Analog forestry can be used as a tool to increase the biodiversity and ecological resilience of a landscape by making use of natural ecological succession and forest functions. Consequently strengthening rural livelihoods can be done through ecological succession and mimicking natural forests. Analog Forestry can also address the following cross-cutting themes: biological connectivity, food security, livelihood improvement, climate change adaptation and social participation.

FORECCAsT by BioClimSol (demonstrator: Maxime JOURDE)

FORECCAsT by BioClimSol is a decision-making tool implemented during the LIFE FORECCAsT project and based on the BioClimSol method, developed by the CNPF. It uses geolocation and is available on smartphone and tablets, directly in the field. It performs a complete diagnosis of forest stands, gives clues about management strategies for existing forest stands or reforestation projects, and enables a silviculture adapted to both local conditions and the climate to come. It is also possible to use it for the management of forest Habitats of Community Interest.

TerrHum (demonstrator: Augusto ZANELLA)

The name TerrHum comes from the abbreviation of the words Terrestrial (not hydromorphic, not submerged soils) and Humipedon (superficial part of a soil, richer in organic matter and composed of organic and organo-mineral soil horizons). It is an application that allows classifying all forest topsoils except submerged ones. The app is built on the indications about humus diagnostic horizons, humus Forms and humus Systems reported and illustrated in 8 articles published in an Applied Soil Ecology Special Issue entitled Humusica (Zanella et al., 2018d, 2018a, 2018c, 2018e, 2018f, 2018g, 2018h, 2018b; Zanella and Ascher-Jenull, 2018a).

TerrHum currently work with iOS but an Androïd version will be published in 2020, thanks to the work of Noémie Pousse et Thomas Bronner.
