DescriptionA range of priorities for maintaining and protecting Tasmania’s freshwater ecosystem values.
Input data
Lineage
The CMPP rating highlights those freshwater dependent ecosystems which have a high priority for active conservation management in the situation where future development and/or changes to land, water or vegetation management are proposed within the catchment which may contribute to a change in aquatic ecological condition or status.
Two versions of the CMPP 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 CMPP1 and CMPP2 rating were developed by the CFEV Technical Management Group and are outlined below.
Data limitations
CMPP 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 CMPP class (VH, H, M or L), for both CMPP1 and CMPP2, was assigned to estuary, karst, saltmarsh, river, waterbody and wetland spatial units using the rules given in Table 1 and Table 2, respectively. For example, if, for a given spatial unit, LTS is High, Naturalness is High and RCV is A, then CMPP (excluding SVs) is VH).
Table 1. CMPP rules using RCV as an input (CMPP1). 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 CMPP1, L = Lower, M = Moderate, H = High, VH = Very High.
