DescriptionA range of priorities for improving the current management of Tasmania’s freshwater ecosystem values.
Input data
Lineage
The CMPI rating highlights those freshwater dependent ecosystems which require immediate implementation of management actions to ensure the protection (and/or restoration) of their significant conservation values.
Two versions of the CMPI output were calculated depending on the input used to describe an ecosystem’s conservation value (RCV or ICV) (see the CFEV Project Technical Report):
Rules for assigning the ecosystem spatial units with a CMPI1 and CMPI2 rating were developed by the CFEV Technical Management Group and are outlined below.
Data limitations
CMPI is a highly derived index and as such inherits all the data limitations of the input data layers and derivation processes.

Assigning values to ecosystem spatial units
The CMPI class (VH, H, M or L), for both CMPI1 and CMPI2, was assigned to estuary, karst, saltmarsh, river, waterbody and wetland spatial units using the rules given in Table 1 and 2, respectively. For example, if, for a given spatial unit, LTS is High, Naturalness is High and RCV is A, then CMPI (excluding Special Values (SVs)) is Low).
Table 1. CMPI rules, using RCV as an input (CMPI1). For Naturalness and LTS, L = Low, M = Medium, H = High; for RCV, A = first group of units selected, B = second group selected, C = remaining group selected and for CMPI1, L = Lower, M = Moderate, H = High, VH = Very High.
