WHAT IS THE NUMERIC SCALE?
16. DO YOU CONSIDER THE INVENTORY ADEQUATE? DESCRIBE ANY STRENGTHS, SHORTCOMINGS, PROBLEMS OR ISSUES ASSOCIATED WITH THIS INVENTORY. – Inventories are largely incomplete Re. hydraulic suitability of sample sites done by outside agencies/consultants. – Need simplification of physical habitat description (fewer parameters). – Need precision of measurement/repeatability. – Need better diagnostic power. – Inventory of large rivers is problematic due to insufficient reach sampling Re. ‘cover’ attributes (e.g. frequency of habitat types/LWD structures) – Need regionalized flow regime/temperature/water quality to resolve ‘overview’ scale problems. – Current inventories often do not qualify results of habitat descriptions with specific flow stages at time of survey. Some investigations have not clearly separated all groups/size classes using mix software or scale analysis this leads to highly questionable results (e.g. mixing population density estimates for separate age groups). – Habitat sui
