Title: Redd count report 1993
Author: National Rivers Authority Northumbria Region
Document Type: Monograph
Abstract:
Redd counts were carried out by the Bailiff Force on the major rivers and their tributaries in the Northumbria Region during November and December 1993. The results are summarized in tables and graphs and a short discussion is included. Unfortunately flood conditions prevented an accurate count in many rivers with many redds being levelled off. Because of this and the fragmentary nature of earlier data, results from the 1993 survey have not been compared with those of previous years. In future years the same sites will be counted to build up a full data base. Habitat data was also collected as part of the redd counting programme.
