The Model LARCH and LARCH-SCAN was developed around 2003. Over time, there were problems encountered due to upgraded programs, ArcView and ArcInfo that changed into ArcGIS. The required update of software has been postponed too long, which requires now an extensive update, and partly new modelling of some features of the model, to bring it to modern standards, compatible with different software types.
The resulting LARCH model will contain the following modules:
- Habitat modelling
- Population and viability modelling
- Landscape connectivity analysis
