The BioClimSol tool

This is the flagship action of the FORECCAsT project

Its objective is to provide forest owners and managers with a decision support tool : a mobile application. Geolocalisable, the application will be usable on tablet, on the field. It will make it possible to carry out a complete diagnosis, to obtain management forest routes for the existing stands, and to implement a silvicultural management adapted to the local conditions and the climate to come.

This action consists of two main steps: data collection and implementation of the application.

Collecting and assembling data

Past and future climate data are analyzed on the territory of the Haut Languedoc Regional Natural Park: rainfall, temperatures, and field data have been collected for several years (topography, pedology and health status of trees).

Deep Soil Pits

Existing data are being complemented by the FORECCAsT project, with the study of about 100 soil pits from May to October 2017, which will enable us to study the water storage capacity of forest soils. It is the capacity of the soil to store and then restore water to the trees. This crucial data should lead to a better location of areas where forests are most vulnerable to climate change.

These pits, which can measure up to several meters deep, will allow to describe the structure of the soils and to take samples in order to better know the quantity of water that a soil can contain. This data can be estimated from soil properties (texture, organic matter content, etc.) through pedotransfer functions. Such functions are widely used in the context of large-scale crops but have yet to be specified for forest soils and adapted to the local context of the Haut Languedoc Regional Natural Park.

This is a large-scale work responding to an important scientific issue !

After defining a sampling strategy, the pit locations have been selected and the agreements are being validated with the owners of the plots.

Health status of trees

A new field campaign will also be conducted to better assess the health status of Douglas-fir trees, using the ARCHI and DEPEFEU methods.

Creating the application

A company will design the application, using data and mathematical models provided by the FORECCAsT project team. The application will be tested by professionals working in forest and their feedback will be obviously used.

Users will then be offered a training in order to well use the application, starting in 2018.
