We are collecting field data from alder forests from Portuguese basins with the main objectives of:
  • Obtaining information on the current extension and status of alder decline in Portugal;
  • Investigating which environmental variables are related to alder susceptibility and to the pathogen expansion;
  • Building a model that predicts alder vulnerability across hydrographic networks.
If you want to contribute to this dataset, we will greatly appreciate if you could do our symptom survey. To this end, you can download bellow all the required documents (protocol and data sheet). We can also assist with any doubts, so please contact us in: alnus.project@gmail.com
