| Ecological Vegetation Classes of the Merri |

![]()
The Merri Catchment covers some 39,040 hectares, but it retains only around 3,112 hectares of currently identified native vegetation[1]. This makes up approximately 8% of the catchment. Most of this vegetation is Plains Grassland or Plains Grassy Woodland Ecological Vegetation Classes (EVC's)
All of the EVC’s [2] listed for the Victorian Volcanic Plain Bioregion within the Merri Catchment meet the criteria set down in the Native Vegetation Plan for the highest priority protection (see table below).
Table 4 - Status of EVCs in Victorian Volcanic Plain Bioregion in the Merri Catchment for reservation and management agreements (based on criteria in the Native Vegetation Plan, p 19). * indicates EVCs having a lower priority in one or both of the other Bioregions
[1] DSE’s website defines Ecological Vegetation Class as meaning a vegetation classification unit defined by a combination of floristics, lifeform, position in the landscape, and an inferred fidelity to particular environments. Each EVC includes a collection of floristic communities (i.e. groups based on co-occurring plant species) that occur across a biogeographic range, and although differing in species, have similar habitat and ecological processes operating. Approximately 300 EVCs have been described for Victoria.
[2] Based on DSE data (DSE 2005), but with some additional areas identified by MCMC staff. It is known that more areas remain to be mapped..
