Unique catchment identifier - the SEPA catchment code (unique) and SEPA catchment name (non-unique).
Barrier_ID - unique barrier identifier from barriers dataset
Easting - barrier Easting
Northing - barrier Northing
Barrier_type - barrier type taken from barriers dataset
Description - gives additional information on a barrier if available.
Delta_DCIScot - increase in national connectivity where a barrier is removed, assuming all barriers downstream have also been removed. The connectivity metric used here in weighted by predicted salmon fry density. Further detail see Buddendorf et al 2019.
PMBs downstream - the number of passable manmade barriers downstream of a barrier.
IMBs downstream - the number of impassable manmade barriers downstream of a barrier.
Cumulative gain - the potential accumulated gain in Delta_DCIScot if the barrier and all downstream IMBs are removed; if there are no IMBs downstream then cumulative gain is equal to Delta_DCIScot.
