Rivers – Additional non-INHABIT sampling stations considered

As stated in the project proposal, D2 activity has considered the possibility of transferring INHABIT project results obtained on newly collected data on dedicated areas to other areas, external to the project. Moreover, the demonstration actions have considered several data sets from Italian regions, already available at CNR-IRSA. Data and information from such sets were included in INHABIT and made available for the aims of other group of actions. The availability of broad sets of data (accounting for some extra 400 samples) has allowed the achievement of activities such as biological validation of river types and assessment of classification uncertainty. In the following table the amount of data collected and used for rivers analyses with indication on considered extra INHABIT data is presented.

NP = Not Planned in the proposal; NA = Not Available; HER: Hydro-Ecoregion.

Extra data from existing datasets were used for:

expanding regional context in classification activities (results available here and in Deliverable D1d1),
accuracy testing (results available here and in Deliverable I3d1),
river types validation (results available here and in Deliverable I1d4),
analysis of the relationships between biological metrics and environmental gradients (results available here and in Deliverable D1d5_EN).
