National Forest Inventory of Andorra

Andorra Research + Innovation has designed a forestry strategy linked to the circular economy promoting forest resilience in the context of climate change. This strategy aims to support public institutions to improve the knowledge of forests, to increase their capacity for conservation and to monitor their evolution both in time and space.

The basic strategic project included in this work strand is the National Forest Inventory of Andorra (INFA, by its acronym in Catalan). The INFA will represent the exhaustive and standardized data collection of the totality of the Andorran forests, comparable to the one carried out in any European country following the guidelines of the Joint Research Center and the European Forest Strategy.

Once completed, INFA will provide a database and interactive cartography with all the biophysical and dasometric data of the Andorran forests at a high spatial resolution. The project has started with intensive field work throughout the publicly owned national forests, where almost two hundred fixed sampling and monitoring plots will be installed to monitor the long-term status of the forest.

The resulting cartography will be presented in an interactive platform for free consultation and simple use for all users. Some of the published variables will be:

  • Barl volume (m3/ha).
  • Density of trees (feet/ha).
  • Basal area (m2/ha).
  • Tree regrowth (%).
  • Average normal diameter (cm).
  • Average height (m).
  • Covered canopy fraction (%).
  • Leaf area index.
  • Total aerial biomass (t/ha).
  • Leaf biomass (t/ha).

This project will serve as a basis for developing other studies in the different work strands of Andorra Research + Innovation and strategic for the country such as:

  • The monitoring of the forests' carbon storage and its carbon sink capacity.
  • The economic valuation of forest products and their use and distribution.
  • The ecological and economic valuation of the ecosystemic functions of forests.
  • Improvement of the fuel and flammability map for forest fire risk.
  • Assessment of the vulnerability of forests to pests and droughts.
  • Assessment of the role of forests in the mitigation of geological hazards.
  • Calculation of the potential distribution of the "gall fer" and other threatened forest species.

Beyond the research, this is a project that intends to provide tools and support to the Comuns and the Government to improve the existing knowledge about our forests.

INFA, from a scientific point of view, receives the support of the Forest Science and Technology Centre of Catalonia, specifically from the Multifunctional Forest Management team, directed by Dra. Míriam Piqué.
