<strong>BURNED</strong> – AREA CHARACTERIZATION<br />
Description of Ecological Vegetation Classes (EVC)<br />
There are 31 broad vegetation types, communities, found within the Kilmore East-Murrindindi<br />
Complex South Fire area; these are called Ecological Vegetation Classes (EVCs). For purposes of<br />
describing the ecological importance, discerning EVCs for field assessment, and for displaying on the<br />
map for this Fire Rehab Plan, some of the EVCs were lumped. The EVCs are components of 4<br />
bioregions that are located within this area, the Highlands Southern Fall (HSF), Central Victorian<br />
Uplands (CVU), Highlands Northern Fall (HNF), and Victoria Alps (VAlp). A description of the EVCs<br />
by bioregion can be found on the DSE, State of Victoria, native vegetation website page<br />
(http://www.dse.vic.gov.au/dse/nrence.nsf).<br />

The grassy dry forest, grassy woodland, valley grassy forest and valley heathy forest were lumped as<br />
the Low Altitude Grassy Dry Forest. The Heathy dry forest, herb-rich foothill forest, shrubby foothill<br />
forest and dry shrubby forest were lumped as the Herb-rich/shrubby Dry Forest. A brief description of<br />
selected EVCs follows.<br />
Among the EVCs present on the fire ground--within the fire perimeter—some are fire sensitive, fire<br />
dependent and others have limited information on fire effects. Some plant communities have a high<br />
value biodiversity asset- high elevation riparian areas, subalpine systems, and dry heathy forest<br />
communities. This assessment will try to address those issues as they pertain to specific EVCs and<br />
the management implications in implementing recommendations in the Biodiversity – Flora<br />
Assessment report.<br />
Heathy Dry Forest (EVC 20)<br />
Within the fire perimeter, Heathy Dry Forest tends to occur on shallow stony soils of low fertility, which<br />
experience seasonal droughts. Generally, Heathy Dry Forest is dominated by a low canopy of Broadleaf<br />
Peppermint (Eucalyptus dives) and stunted Messmate (Eucalyptus obliqua). The understorey<br />
features a number of species of the Australian heath family, the Epacridaceae including Rosy<br />
Baeckea (Baeckea ramosissima), Austral Grass-tree (Xanthorrhoea australis), the rare Creeping<br />
Grevillea (Grevillea repens), Silver Banksia (Banksia marginata) and Bushy Hakea (Hakea sericea).<br />
Silvertop Wallaby-grass (Chionochloa pallida) is a common, often dominant, member of the ground<br />
layer. Its dominance at some sites may reflect that the site has remained unburnt for a long period. It<br />
is clear that fire regimes are of great importance to the understorey species composition of this<br />
community.<br />
Cool Temperate Rainforest (EVC 31)<br />
Non-eucalypt forest with a largely closed canopy dominated by Myrtle Beech (Nothofagus<br />
cunninghamii) and Southern Sassafras (Atherosperma moschatum). Occurs in high rainfall areas<br />
nested within more extensive stands of Wet Forest and Montane Wet Forest. Blackwood (Acacia<br />
melanoxylon) may form part of the closed rainforest canopy in some stands. The understorey features<br />
an array of ferns, including Soft Tree-fern (Dicksonia antarctica), Hard Water-fern (Blechnum wattsii)<br />
and Mother Shield-fern (Polystichum proliferum). Mosses and liverworts are abundant. Some areas<br />
of Cool Temperate Rainforest are within broader sites of rainforest significance.<br />
Damp Forest (EVC 29)<br />
Damp Forest is a widespread ecological vegetation class occupying a range of sites on a variety of<br />
soils and aspects between 200 to 1000 m in elevation. Messmate and Mountain Grey Gum<br />
(Eucalyptus cypellocarpa) are the characteristic dominants in the overstorey which is often in excess<br />
of 50 m in height. Mountain Ash may be a locally dominant canopy species. The species comprising<br />
the shrub layer includes Hazel Pomaderris (Pomaderris aspera), Prickly Moses (Acacia verticillata)<br />
and Snow Daisy-bush (Olearia lirata). The ground layer is a variable assemblage of forbs and ferns.
Grassy Dry Forest / Valley Grassy Forest (EVC’s 22 & 47)<br />
These EVCs were mapped as the Low Altitude Grassy Dry Forest in this plan. This community occurs<br />
on relatively exposed aspects, often on moderately fertile acidic duplex soils. It is dominated by Red<br />
Box (Eucalyptus polyanthemos), Red Stringybark (Eucalyptus macrorhyncha), Long-leaf Box<br />
(Eucalyptus goniocalyx) and Yellow Box (Eucalyptus melliodora). The open grassy understorey<br />
commonly includes Commonly present are Kangaroo Grass (Themeda triandra), Grey Tussock-grass<br />
(Poa sieberiana), Stinking Pennywort (Hydrocotyle laxiflora), Blue Pincushion (Brunonia australis),<br />
Green Rock-fern (Cheilanthes austrotenuifolia), Cotton Fireweed (Senecio quadridentatus) and<br />
Common Raspwort (Gonocarpus tetragynus). These communities comprise the critically endangered<br />
White Box - Yellow Box - Blakely's Red Gum Grassy Woodlands and Derived Native Grasslands.<br />
Herb-rich Foothill Forest / Shrubby Dry Forest / Shrubby Foothill Forest<br />
Herb-rich Foothill Forest (EVC 23)<br />
Open forest usually 20 to 35 m in height made up of one or more of the following eucalypt species:<br />
Narrow-leaf Peppermint (Eucalyptus radiata), Messmate, Manna Gum (Eucalyptus viminalis) and<br />
Candlebark (Eucalyptus rubida). The sparse low shrub layer consists normally of two species:<br />
Common Cassinia (Cassinia aculeata) and Silver Wattle (Acacia dealbata). The ground layer is<br />
typified by a seasonally high cover, and diverse forb component, including Kidney-weed (Dichondra<br />
repens), Weeping Grass (Microlaena stipoides), Bidgee-widgee (Acaena novae-zelandiae), Cinquefoil<br />
(Geranium potentilloides), Grey Tussock-grass, Soft Tussock-grass (Poa morrisii), and Prickly<br />
Woodruff (Asperula scoparia). Austral Bracken (Pteridium esculentum) is usually present in the<br />
Victoria Alps Bioregion, and may tend to dominate the ground layer if frequently disturbed by fire.<br />
Shrubby Dry Forest (EVC 21)<br />
Open forest up to 25 m in height. Shrubby Foothill Forest has a relatively dense and varied shrub<br />
layer, but tends to lack a diverse ground layer. It is widespread on higher slopes, particularly between<br />
400 and 900 m in elevation. The dominant trees are Messmate and Narrow-leaf Peppermint. A wide<br />
variety of shrubs characterise this community across its range. Common among these are Narrowleaf<br />
Wattle (Acacia mucronata), Dusty Miller (Spyridium parvifolium), Handsome Flatpea (Platylobium<br />
formosum), Prickly Bush-pea (Pultenaea juniperina), Common Cassinia, and Pink-bells (Tetratheca<br />
ciliata). The ground layer includes Common Raspwort and Grey Tussock-grass. Forest Wire-grass<br />
(Tetrarrhena juncea) and Austral Bracken (Pteridium esculentum) are commonly present, and<br />
sometimes dominant.<br />
Shrubby Foothill Forest (EVC 45)<br />
It is similar in structure to Herb-rich Foothill Forest, has a denser and varied shrub layer, but tends to<br />
lack a diverse ground vegetation layer. It is widespread on higher slopes, particularly between 400m<br />
and 900m elevation, both north and south of the Great Dividing Range. The dominant trees are<br />
Messmate and narrow-leaf peppermint, also sliver-top, mountain grey gum, and scentbark may occur.<br />
Grassy Dry Forest (EVC 22)<br />
It occurs on relatively exposed aspects, often on moderately fertile acidic duplex soils. It is best<br />
developed in the hills to the north-east of Melbourne and in the foothills of the Goulburn Valley. It is<br />
dominated with the same eucalypts as Valley Grassy Forest (EVC 47), with which it is often<br />
associated. The eucalypts include red box, red stringybark, long-leaved box, and yellow box.<br />
Montane Damp Forest (EVC 38)<br />
A tall forest up to 40m in height, dominated in its lower altitudinal range by Mountain Grey Gum<br />
(Eucalyptus cypellocarpa), Messmate, Narrow-leaf Peppermint and occasionally Manna Gum. At<br />
higher altitudes, Montane Damp Forest is often dominated by pure stands of Alpine Ash (Eucalyptus<br />
delegatensis). Montane Damp Forest features an open to rather dense layer of tall shrubs, amongst<br />
which Silver Wattle, Blackwood, and Mountain Hickory Wattle (Acacia obliquinervia), are prominent.<br />
The ground layer is characterised by grasses and herbs. Mother Shield-fern (Polystichum proliferum)<br />
is common in moister sites.<br />
Lowland Forest (EVC 46)<br />
Lowland Forest is closely related to the Herb-rich Foothill Forest and Shrubby Dry Forest usually<br />
occurs at lower elevations, yellowish gradational soils and leached sands of low fertility. Its floristic<br />
understorey is similar to heathy woodlands and heathlands. The canopy includes Silver-top,<br />
Yertchuk, and Messmate. Occasionally, white stringybark and brown stringybark are present.
Montane Riparian Thicket (EVC 41)<br />
Dense thickets of Mountain Tea-tree (Leptospermum grandifolium) occur along drainage lines in<br />
montane and sub-alpine areas. Montane Riparian Thicket is associated with a number of other<br />
ecological vegetation classes, often arising at the outlets of sub-alpine heathlands, and intergrading<br />
with Cool Temperate Rainforest or Riparian Thicket at lower altitudes. The canopy of Montane<br />
Riparian Thicket may vary in height up to approximately 15m depending on exposure and altitude.<br />
Cool Temperate Rainforest dominants Myrtle Beech and Sassafras (Atherosperma moschatum) are<br />
frequently sub-dominant in this community. Soils are often peaty. A thick substrate of Sphagnum can<br />
be present. The ground layer flora includes Alpine Water-fern (Blechnum penna-marina), Forest<br />
Sedge (Carex alsophila), and Hard Water-fern (Blechnum wattsii). The Baw Baw Berry (Wittsteinia<br />
vacciniacea), although considered rare in Victoria (Gullan et al 1990), is frequently encountered as a<br />
low shrub within this community. It is endemic in the Victorian Central Highlands.<br />
Montane Wet Forest (EVC 39)<br />
Montane Wet Forest occupies south-facing slopes, gullies and plateaus generally above 900 m. Soils<br />
are deep, fertile and well-drained. The canopy may grow to more than 60 m, and consists of pure or<br />
mixed stands of Alpine Ash (Eucalyptus delegatensis), and Shining Gum (Eucalyptus nitens). Manna<br />
Gum (Eucalyptus viminalis) may be a co-dominant in the Blue and Royston Ranges. The tall second<br />
storey includes Myrtle Beech and Forest Wattle (Acacia frigescens), which grow above a dense layer<br />
of Soft Tree-ferns (Dicksonia antarctica). At ground level, Hard Water-fern (Blechnum wattsii),<br />
Bat'swing Fern (Histiopteris incisa) and Mother Shield-fern are characteristic of this EVC. Although<br />
closely related to Wet Forest EVC, the floristic distinction lies in the substitution of most of the<br />
characteristic shrubs and trees.<br />
Riparian (Higher Rainfall) (EVC 18, 641 and 40)<br />
Riparian Forest (EVC 18)<br />
Riparian Forest is a tall forest of river banks and alluvial terraces. It is characteristically dominated by<br />
Manna Gum, with Silver Wattle, Blackwood, Hazel Pomaderris (Pomaderris aspera), Victorian<br />
Christmas-bush (Prostanthera lasianthos) and Prickly Coprosma (Coprosma quadrifida) in the shrub<br />
layer. The richness of the understorey of Riparian Forest is noteworthy, with a wide variety of<br />
terrestrial species as well as a suite of semi-aquatic plants. Usually present are Fishbone Water-fern<br />
(Blechnum nudum), Tall Sedge (Carex appressa), Mother Shield-fern, Swamp Club-sedge (Isolepis<br />
inundata), Small-leaf Bramble (Rubus parvifolius) and Soft Tree-fern. Examples include the stand of<br />
Buxton Gum (Eucalyptus crenulata) on river flats beside the Acheron River south of Buxton, where<br />
the atypical understorey combines elements of Wet Heathland and Floodplain Wetland Complex, as<br />
well as many of the usual species listed above.<br />
Montane Riparian Woodland (EVC 40)<br />
Open Forest or Woodland to 20 m in height restricted to peaty alluvial soils of perennial, meandering<br />
stream terraces, insipient drainage lines and localised depressions at elevations above 600 m...<br />
Eucalyptus camphora ssp. humeana (Mountain Swamp-gum) is the common overstorey species<br />
across the fire ground. The understorey supports a wide range of shrub species adapted to sites with<br />
poor drainage such as Baekea gunniana, Epacris microphyllum, Epacris breviflora grandifolium while<br />
the field layer is dominated by a range of semi-aquatic sedges, rushes and ferns often forming dense<br />
swards.<br />
Swampy Riparian Woodland (EVC 83)<br />
This EVC occurs in association with broad drainage lines, river terraces and minor floodplains or<br />
adjacent to streams. Soils are mostly of silt-rich river sands and gravels. The overstorey of this<br />
vegetation type has a woodland structure which often forms mosaics with wetlands by sedges, rushes<br />
and many other plants associated with riparian environments. Swamp Gum (Eucalyptus ovata) and<br />
Manna Gum are the dominant overstorey species. The understorey shrubs consist of Blackwood,<br />
Swamp Paperbark (Melaleuca ericifolia), Hemp Bush (Gynatrix pulchella), Tree Violet (Hymenanthera<br />
dentate) Black Wattle (Acacia mearnsii) and Snowy Daisy Bush (Olearia lirata). The ground stratum<br />
is the most characteristic feature of this EVC and is normally dense with graminoids including Leafy<br />
Flat-sedge (Cyperus lucidus), Tall Sedge, Common Reed (Phragmites australis) and Common<br />
Tussock Grass (Poa labillardieri).
Sub-alpine Woodland (EVC 43)<br />
Grows on a wide range of geologies and aspects, in the higher altitudinal levels above 1200 m.<br />
Rainfall is relatively high and snow may persist for long periods over winter. Soils are generally<br />
skeletal sandy clay loams with a rich humus topsoil layer. A low, open woodland to 10 m tall<br />
dominated by Snow Gum (Eucalyptus pauciflora), The understorey may variously consist of a rich<br />
suite of grasses and herbs, or a dense layer of woody shrubs such as Mueller's Bush-pea (Pultenaea<br />
muelleri), Alpine Oxylobium (Oxylobium alpestre), Alpine Pepper (Tasmannia xerophila) and Alpine<br />
Wattle (Acacia alpina).<br />
Swampy Riparian Complex (EVC 126)<br />
A combination of elements described in other EVCs including swampy riparian woodland and riparian<br />
thicket, riparian forest. The potential component EVCs of this mapping unit includes Creekline Herbrich<br />
Woodland, Gully Woodland, Shrubby Gully Forest, Fern Swamp, Swampy Riparian Woodland,<br />
Swampy Woodland and Swamp Scrub. Structurally variable vegetation typical of swampy to<br />
waterlogged, low gradient drainage-lines (or associated hillside soaks).<br />
Wet Forest (EVC 30)<br />
Wet Forest is usually dominated by Mountain Ash (Eucalyptus regnans), forming very tall forests<br />
sometime above 80 m in height. Wet Forest occurs where there is the co-occurrence of deep well<br />
drained soils in high rainfall areas and cloud cover at ground level is frequent. Wet Forest is largely<br />
restricted to elevations above 700 m ASL (up to 1000 m) on southerly aspects, plateau and other<br />
physiographic setting that have over millennia afforded some protection from frequent fire. The<br />
second storey of trees includes Silver Wattle (Acacia dealbata) and Blackwood and may reach 35 m.<br />
The shrub layer includes Hazel Pomaderris (Pomaderris aspera), Blanketleaf (Bedfordia<br />
arborescens), Musk Daisy-bush (Olearia argophylla), and Banyalla (Pittosporum bicolor) which grow<br />
to 20 m in height. A dense layer of Soft Tree-fern and Rough Tree-fern (Cyathea australis) to 5m is<br />
characteristic. The moist, shaded ground layer supports Mother Shield-fern (Polystichum proliferum),<br />
Hard Water-fern (Blechnum wattsii), Shade Nettle (Australina pusilla) and White Elderberry<br />
(Sambucus gaudichaudii). In the wettest fern-gullies, Shiny Shield-fern (Lastreopsis acuminata) and<br />
Mother Spleenwort (Asplenium bulbiferum) are common.<br />
Cool Temperate Mixed Forest (EVC yet to formally described but is generally accepted and is<br />
listed under the FFG Act)<br />
Cool Temperate Mixed Forest is effectively Cool Temperate Rainforest with an emergent eucalypt<br />
canopy of wet or montane forest eucalypt species. A formal definition of Cool Temperate Mixed Forest<br />
has recently been proposed - a closed rainforest understorey comprising mostly rainforest tree taxa<br />
with a collective projected foliage cover of at least 70% and an overstorey of eucalypts (Eucalyptus<br />
nitens, E. regnans and E. delegatensis are typical) with at least 10% foliage cover or more. In the<br />
absence of fire for long periods or where fire intervals are extended, secondary rainforest and mixed<br />
forest stands may be extensive. Nematolepis wilsonii (Shiny Nematolepis), Vulnerable nationally<br />
(EPBC), Listed as threatened in Victoria (FFG), and as vulnerable in Victoria (DSE) occurs in Cool<br />
Temperate Mixed Forest with emergent old growth Mountain Ash, and is endemic to this fire area.<br />
Rocky Outcrop Shrubland (EVC 28)<br />
This is a catch all EVC type that is a convenient aggregate of a range of structurally and floristically<br />
distinct entities. Variants are generally poorly described, mapped and sampled. Rocky outcrops are<br />
frequently of botanical interest because they contain a range of unusual micro-habitats, from highly<br />
exposed rock-faces, to damp, sheltered crevices. Rocky outcrop shrublands occur across the fire<br />
ground on a range of geological substrates including (as examples):<br />
Various EVCs, comprising Treeless Sub-alpine vegetation mapping unit<br />
Sub-alpine Wet Sedgeland (EVC 917)<br />
Treeless tussocky (grassy-sedgy) vegetation of wet plains on sub-alpine (apparently to alpine) creek<br />
flats, with patchy inter-tussock matting of Sphagnum spp. (with few large Sphagnum hummocks, and<br />
patchy Callistemon shrubland, both primarily on upper margins). Relatively species-poor where<br />
tussocks or sward density is moderate to high.<br />
Sub-alpine Wet Heathland (EVC 210) with Alpine Valley Peatland (Bog) Mosaic<br />
Virtually treeless and characterised by a dense layer of low heathy shrubs, with a number of sedges<br />
and rushes in the understorey. It occurs in soaks or along small streams in sub-alpine to alpine areas.
Rainfall is generally greater than 1000 mm per annum, and during winter, this EVC can tolerate long<br />
periods of snow cover and low temperature. Deep, peaty, sodden soils are usually covered by a layer<br />
of Peat Moss Sphagnum spp. EVC present but unmapped across the study area, Montane Bog (EVC<br />
966) Low heathy, sedgy-mossy shrubland to herbland. Montane bog occurs in boggy valley habitats<br />
associated with the heads of drainage-systems in montane areas subject to cold-air accumulation.<br />
Across the central Highlands the following shrub species may be locally common and dominant<br />
Baeckea utilis, Epacris brevifolia, Epacris paludosa, Sphagnum spp. and Empodisma minus.<br />
Associated species include Richea victoriana, Oxalis magellanica, Wittsteinia vaccinacea and<br />
Blechnum penna-marina. Larger trees and tall shrubs such as Nothofagus cunninghamii and/or<br />
Leptospermum grandifolium can be present on the verges or scattered through the vegetation.<br />
Sub-alpine Shrubland (EVC 42)<br />
A generally dense shrubland of sub-alpine and alpine areas frequently found on sheltered sites<br />
fringing Sub-alpine Woodland where snowfall persists as ground cover in winter months and where<br />
rainfall is high. It occurs on a range of geologies on shallow soils.<br />
Alpine Grassy Heathland (EVC 1004)<br />
High altitude open heathland with inter-shrub spaces dominated by tussock grasses and a wide range<br />
of forbs. It occupies a wide range of habitats generally on slopes above 1400m ASL where exposure<br />
and frost are limiting to tree growth.<br />
EVC’s of extremely minor occurrence within the fire ground<br />
Granitic Hills Woodland (EVC 72)<br />
Mainly restricted to granite rocky outcrops and structurally consists of a low open woodland. A range<br />
of Eucalypts may be locally dominant including Eucalyptus goniocaylx, E. melliodora and E.<br />
machrorhyncha. The shrub layer is typically sparse above a field layer of forbs, grasses and<br />
bryophytes.<br />
Plains Woodlands (EVC 803)<br />
An open, eucalypt woodland occurring on a number of geologies and soil types. It occupies poorly<br />
drained, fertile soils on flat or gently undulating plains at low elevations. The understorey consists of a<br />
few sparse shrubs over a species-rich grassy and herbaceous ground layer.<br />

This table is important in that it demonstrates the concern for decreased fire return intervals in<br />
Victoria. The state has been experiencing fires about every 3 to 5 years, is in a serious drought and<br />
has a serious problem with noxious weed infestations (pest plants). It is because of this we are not<br />
only proposing immediate Emergency Stabilisation treatments but are proposing long-term<br />
rehabilitation and research monitoring to study fire effects and seedling recruitment in populations that<br />
have been subject to repeated high intensity wildfires. Frequent fires are a concern in the damp, wet<br />
and montane wet forests for Mountain and Alpine ash regeneration, in the lowland, low altitude,<br />
lowland dry forests to messmate eucalyptus forests.<br />
