Demo landscape

The "demo landscape" is the "Klausbachtal", one of the three main valleys of Berchtesgaden Nationalpark. The demo landscape is ~2300ha and comes with vegetation, climate data, and disturbance data and is ready to run.

Species parameters

Thom et al 2024 (https://doi.org/10.1016/j.dib.2024.110662) provide a collection of iLand species parameters for 150 species and provenances Europe, North America, and Japan. The repository contains the parameter table in SQLite format (all_species_database.sqlite).

Per default, all species are "switched on" in this database - this is indicated by a value of "1" in the column "active". For use in a specific region it is good practise to turn off unused species (set active to 0), which makes iLand run faster (with a lower memory footprint) and produce less output data.
Note that the species parameter table shipped with the "demo landscape" is set up for Central Europe.
