Trophic level index

Measure of nutrient status of lakes

The trophic level index (TLI) is used in New Zealand as a measure of nutrient status of lakes.[1] It is similar to the trophic state index but was proposed as alternative that suited New Zealand.[2]

Not to be confused with Trophic level.

The system uses four criteria, phosphorus and nitrogen concentrations, as well as visual clarity and algal biomass weighted equally.[3]
