SUMMARY

The Waurn Ponds Creek valley has little indigenous vegetation following over 150 years of European settlement, although several old River Red Gums, Blackwoods and in-stream aquatics survive.

Some exotic and non-indigenous trees planted over that time provide a small amount of faunal habitat.

Recent planting has focused on locally indigenous trees and shrubs but it has been at an ad-hoc level rather than based on a revegetation plan for the valley as a single ecological unit. These plantings generally lack botanical structure with fewer shrubs and ground-cover plants than are desirable to control weeds.

Important indigenous and planted trees and other vegetation have been identified and sited on plans, and recommendations made for their protection.

Much of the open ground along the valley, between the creek and abutting private property, is regularly mowed however the south side downstream of Torquay Road is a weedy "wilderness."

Major weed infestation, notably of boxthorn, briar, fennel and gorse, have been sprayed and killed, however the dead vegetation remains.

Significant weed species have been listed, sited on plans and their removal prioritised.

Revegetation of the valley downstream of Ghazeepore Road should continue as a whole rather than in piecemeal fashion, using locally indigenous species.

The valley contains three broad zones - the stream banks (riparian), low-lying land (flood-land) and more elevated land (rising) - and planting guides are recommended for each.

A planting plan has been developed recommending species and spacing for the different sites along the valley.


WAURN PONDS CREEK, FLORA SURVEY AND REVEGETATION OUTLINE

Purpose

The purpose of this report is to

Boundaries

While Waurn Ponds Creek rises in the Barrabool Hills and incorporates a large area of rural land in its headwaters, this report is confined to the section downstream of Ghazeepore Road to the eastern end of the South Barwon Recreation Reserve.

Consequently only limited comment is made of the upstream section and the land at the confluence of the creek with Barwon River.


SIGNIFICANT PLANTS, INDIVIDUALS AND GROUPS

Introduction

The significant vegetation may best be described in terms of

While there are scattered indigenous plants along the creek valley, notable tussock and other grasses, it would be difficult to physically separate them from the overwhelming weed infestation. They are mainly confined to the un-mowed creek banks, but as widespread and intense replanting takes place, their contribution to revegetation will be minimal.

Site inspection prior to herbicide spraying would enable an assessment to be made on the feasibility of protecting any indigenous plants noted at the time.

By contrast, indigenous in-stream vegetation is prolific with Common Reed, sedges and water-ribbons widespread. It is impracticable to plot these plants on plans. Similarly non-invasive aquatic weeds have not been specifically marked on plans since eradication, even control, seems neither necessary nor practicable.

Mowing of the open land has made any formal assessment of the flora difficult, and there appears to be little indigenous vegetation remaining in the overwhelming weed growth.

There are a number of mature Black and Golden Wattles along the corridor, however since these plants are not long lived, they could not be classed as remnants. They may have grown from seeds produced by similariy-aged trees however, given the extent to which both species have been used in earlier replantings, they could not be classed as being of true local provenance.


Significant plants and groups of plants

River Red Gum Eucalyptus camaldulensis

Individual old trees, some possibly pre-dating European settlement, are scattered along the creek, most at the water's edge.

Other younger trees are also present in fair numbers along the creek, but whether these have been planted or are natural regeneration is not immediately apparent - they are probably a mix of both.

Except where they form an obvious planting, they have been marked on the appropriate maps along with the obviously older trees.

Dead red gums that remain in the creek bed are also recorded since these retain hollows used by fauna.

Risks to existing living trees include storm-damage, insect-attack, vandalism and age-related die-back, while wind and fire are hazards to the dead trees.

The best method of protecting both living and dead trees is to incorporate them into re-planting projects. This should be a priority in determining where revegetation takes place.



Blackwood Acacia melanoxylon

This is the longest-living of local wattle species but it seems unlikely any of the trees along the creek pre-date European settlement. Some, however, are likely to be natural regeneration from seed and may retain local provenance genetics.

Others are obviously planted, their provenance unknown.

Because they are a dense-foliaged trees, they are useful bird habitat, and since they are generally long lived, the existing trees should be given protection.

These existing trees should be incorporated into revegetation projects.



Black Wattle A. mearnsii, Golden Wattle A. pycnantha

There are isolated specimens of both species but, given their relatively short lifespan, they could not be classed a remnant specimens. In addition, although not in plantations, they may have been planted.

There seems little need to specifically protect them given their short lifespan and unknown provenance.



Tangled Lignum Muehlenbeckia cunninghamii

Although it was probably common on the lower reaches of the creek, few plants now exist. While they are useful habitat, there is concern that the plants impeded the flow of the floodwaters.

Replanting of a small number downstream of Bailey Street, particularly on the extensive flood-plain, would be desirable in ecological terms



Cumbungi Typha orientalis

Another plant seen as an impediment to free flood-water movement, Cumbungi can be invasive to the extent it becomes a dominant part of the stream-bed flora. Some plants exist upstream of Barwon Heads Road but they are not apparently causing any problems at this time.

Leave the existing Cumbungi in-situ unless, or until, it causes demonstrable problems.



Common Reed Phragmites australis

Dense beds of Common Reed exist in the lower reaches of the creek and form useful habitat for several species of birds. It is seen as less of a potential problem in relation to impeding flood-waters than Cumbungi.

Leave the existing beds of Common Reed in-tact.



Other aquatics

A range of aquatic plants, including sedges, rushes and water-ribbons exist as in-stream vegetation along the creek.

Since there is no need to attempt any revegetation in the waterway at this time, no detailed assessment of these plants has been made.


Non-indigenous mature trees

There are now some non-indigenous Australian trees, and other exotics, that are mature, providing both shelter and food supplies for birds and mammals.

While there should be a long-term strategy of eliminating non-indigenous exotic trees, and a  short-term objective of preventing their regeneration, they are fulfilling a habitat need and they should receive some reasonable level of protection until the indigenous species that are planted attain maturity.

There is an added component, however, notably in the case of pines, in the risk to public safety.

Old trees, particularly where they span paths or open, recreational space, need regular, perhaps annual, assessment as to human safety.


Significant plants and groups of plants

Upstream of Barwon Heads Road

The Rotary Club sponsored plantings on the west side of the creek, upstream of Barwon Heads Road, have established well in the short time since they were undertaken.

However, the block nature of plantings tends to over-formalise them, and there is a lack of prickly-foliaged shrubs, e.g. Hedge Wattle, Prickly Moses Wattle, which would help in providing small bird nesting habitat.

The species used, while suitably indigenous, are not fully consistent with those proposed in this report, however there is no suggestion that the plantings should be modified substantially. In the most recent double block, the plants appear to be too closely spaced to fully maximise the number used - the same quantity could have been dispersed over a much larger area.

Future plantings should be planned and carried out according to the accepted layout in this report.


Cobbin Farm, Highmont Drive

This area has a large number of exotic and non-indigenous Australian trees and shrubs in an area that has high recreational use. Among them are a few invasive plants such as English Ivy, and these should be given high priority in weed removal programs. (see also under Plant Pest Species in following pages.)

However the cultural value of the Cobbin Farm gardens should be protected except where invasive weed species are involved


Upstream of Cobbin Farm to Pioneer Road

The planting on the banks in this section of Waum Ponds Creek is very good. It contains a range of locally indigenous species including Manna Gum, River Red Gum, Silver Wattle and Black Wattle.

While the use of Manna Gum in this riparian zone is unfortunate, the trees are growing well and it is possible to integrate them into the planting of the same species on the other sites.

There is, however, no shrub or ground-cover layer, and some phalarus and other weed infestation is of concern. This can be overcome by spraying of the weeds, planting with shrubs and poa tussocks, and mulching.


Upstream of  Pioneer Road

The Lions Club planting here is successful, however there needs more ground-cover e.g. poa tussocks and shrubs. Existing River Red Gums have been incorporated into the planting providing protection against storm-damage.

There are a number of Tussock Grasses, Poa labillardieri on the north-west side of the creek, upstream and opposite this planting. It would be desirable to protect these plants by incorporating them into any future extension. Herbicide spraying before planting would need to be carefully done.

It is desirable to extend the planting along both banks of the creek upstream of Pioneer Road.

PEST PLANT SPECIES

Introduction

Given the long history of European use of the creek valley, it is hardly surprising that there is a very long list of weeds.

The vast majority of these are pasture grasses and weeds such as plaintains, mallows, brassicas, clovers, vetch, oxalis, thistles etc. There are also some garden escapes, in places the result of illegally dumped garden refuse.

In most cases it is difficult, even impossible, to remove or control them given the continual input of seeds from outside the area. The best treatment would be to provide indigenous plants as competition.

The open grassed areas are mowed regularly and this helps control the weeds by preventing seed-production. This is recommended to continue even as the woodland plantings take place.

There are some serious weed infestation in the un-mown areas along the creek banks which have been controlled by herbicide spraying.

PRIORITY 1 PEST SPECIES

(Note, this list is in alphabetical, not priority order. All of these 11 species require immediate and on-going control.)

Hawthorn Crataegus monogyna
Not widely distributed along the creek, most of the plants noted are in the upper third (map D) and near Bailey Street (map  B).

Cut and paint with herbicide in accordance -with Council's management practices.

Artichoke Thistle Cynara cardunculus

Particularly plentiful in the lower sections of the creek where it is generally well-managed by spraying, particularly before flowering. Some plants are further upstream particularly near Ghazeepore Road. Dispersal of seed by wind rather than water means it is usually on flat land well above the creek.

This species should be spot-sprayed before flowering takes place. Mowing/slashing is also effective in preventing it fowering.

Desert Ash Flaxinus rotundifolia

This is a serious environmental woody weed that has had a substantial impact by colonising many sections of the Barwon River riparian habitat.

The major infestations along the Waurn Ponds Creek are upstream of Barwon Heads Road towards Winter Street but there are other plants further along the valley.

Removal of some of the plants has been carried out already, and this should continue. Isolated plants high in the catchment should receive priority treatment to reduce the spread of the species.

Fennel Foeniculum vulgare
Already subject to control by spraying, it is desirable to continue, even expand, the treatment.

In isolated clumps, or in environmentally sensitive areas close to other plants or the water, cutting and painting may be necessary.

An environmentally invasive weed; management should continue and be expanded.

Broom Genista monspessulana

Another highly invasive weed, there is a large amount growing on the south bank downstream Of Torquay Road to at least Bailey Street.

This should be treated urgently to limit the extent to which it can spread.

English Ivy Hedera helix

Environmentally invasive, ivy is spread in part by the dispersal of seeds by birds.

There is only a small area of ivy, near Highmont Drive, and this should be removed.

Privet Ligustrum vulgare

At the present time (May) most have clusters of ripe berries which may be eaten by some birds, thus potentially extending their distribution. However Privet is a garden plant and fresh introductions in this manner may continue.

A number of bushes have been identified and these should be removed prefereably by cutting and painting the stumps according to Council's woody weed removal procedures.

African Boxthorn Lycium ferocissimum

Except where marked on the attached maps, all boxthorn infestations have been sprayed and killed. The dead bushes remain in-situ and in time these will be an impediment to revegetation. In addition to that, they area harbour for rabbits and sparrows.

However they also serve as cat-proof habitat for wrens and some other native birds, and since most are on the bank of the creek, they help hold the erodable soil together. To physically remove them from the site would damage the creek banks, and the cost would be high.

It is recommended that the dead bushes be burnt in-situ to make revegetation easier and to remove the rabbit harbour, while allowing the roots to remain in the soil.

This would also encourage regrowth of any root-stock and germinate seeds, allowing a follow-up spraying program if necessary.

However, given that wrens and other birds may use the boxthorn for nesting, burning should not take place between August and December.

Any living boxthom bushes should be sprayed according to routine management prescriptions. Those under existing cypress trees should be removed either manually or by use of cut-and-paint methods.

Removal of dead bushes and treatment by spraying or cut-and-paint of living plants be a priority.

Sweet Briar Rosa rubiginosa

A spiny plant that can cause problems in revegetation work because of its stiff branches and hard thorns that cover them.

Most of the briar has been killed by spraying and these plants should be removed. Any growing plants should be sprayed, then removed.

Blackberry Rubus fruticosus spp. agg.

Spraying has controlled the plant to a large extent and any remaining thickets should be treated.

Removal of dead blackberry should be carried out to allow easier revegetation.

Gorse (Furze) Ulex europaeus

As for African Boxthorn detailed above.

REVEGETATION PLANS

Objectives

With so little of the original flora remaining, revegetation of the creek reserve should be carried out to achieve several things.
  1. replicate as far as possible the original riparian flora
  2. provide faunal habitat
  3. create an attractive visual impact
  4. allow easy and safe access for people using the bike/pedestrian paths
  5. minimise maintenance demand
  6. allow floodwaters to flow with minimum interruption
  7. minimise fire and other risks to abutting properties
  8. allow appropriate recreation development

Vegetation structure

Waurn Ponds Creek is in a linear reserve bounded on both sides by residential or commercial development. In places, the creek,has been mechanically cleaned out, and re-aligned, and for the most part consists of a steep-banked channel in an otherwise flat landscape.

There are some minor flood-plains, and the balance of the land rises gently to the private property boundaries which are mainly above predicted flood level

This creates three main zones, with some minor sub-zones, along the reserve viz


Revegetation priorities

The initial priority would seem to be the establishment of tree-cover along the water-course. There should be a structure to the planting so that trees, shrubs and ground-cover species develop simultaneously.

In some earlier plantings, there has been an emphasis only on trees and as a result the understorey has become dominated by weeds. This is the case upstream of Cobbin Farm.

Since these weeds, mainly phalarus and similar plants, are easily removed, spraying by Council staff and follow up re-planting with shrubs and ground-covers by volunteers would be appropriate.

There are also sections of the creek, e.g. at Camdell Court, where there are many mature and semi-mature indigenous trees, but there are also many weeds including boxthorn and Pepper-corn Trees.

Since these are substantial plants, it would seem appropriate to allocate their removal to a group like Green Corps or ATCV, rather than inexperienced volunteers. Fill-in planting could be done by either.

The four main sources of labour to undertake the revegetation work are

Since Council and the Friends group are most closely associated with the project, it would seem appropriate that the sites chosen for replanting be negotiated between the two.

Weed spraying and large tree removal work would be Council responsibility, while volunteer groups working mainly under Friends guidance would be best used as tree-planters.

The first areas to be planted should be on both banks along the creek

  1. opposite Woolvet Avenue i.e. adjacent to the existing Rotary Club plantings - riparian and rising land; rationale - continuity of Rotary Club work.
  2. at Winter Street upstream of the pipe crossing - riparian and flood-plain; rationale - local residents interest, small flood plain well suited to planting.
  3. at Camdell Court - riparian; rationale - some excellent remnant plants but the area with woody weeds; some open stream-side bank well suited to planting.
  4. upstream of Pioneer Road i.e. Lions Club plantings - riparian; rationale - continuity of Lions Club work.
  5. in the vicinity of Rossack Drive - riparian; rationale - need for a site near the upper reaches.




Some community interest has already been shown at all except the Rossack Drive site, and this should be supported as soon as possible.

With Council, Barwon Water and C.C.M.A currently carrying out revegetation along the Barwon River corridor, an objective of the Waurn Ponds Creek work should be to connect with and integrate into the existing and future work along the river and on Belmont Common.


Performance guide

To measure the success of the revegetation it is recommended that

Since birds are excellent bio-indicators, and are easily recorded, this is a better method than using other formal groups. The counts should also involve local residents as a community-input

The symbols used on the sites list are
R for the riparian zone
F for the flood land
P for the rising land

The symbols used on the plant list are
T for trees above 4m height
S for shrubs 1m to 4m height
G for low-growing plants
C for creeper

Spacing should not be rigidly adhered to, for in some situations this may vary, but average figures are shown in metres.
Where R (random), no particular spacing needs to be adopted

Riparian

The bed of the creek with its aquatic in-stream vegetation, the often-steep banks, and a short distance on top of the banks, are included in this definition.

Depending on the alignment of the creek, the width of bank-top varies from only 2m on the outside of the bend to 4-5m, or more, on the inside bend.

The objective is to vegetate this section with trees, shrubs, tussocks, flax-lilies and mat-rushes densely enough to provide a closed canopy and inhibit weed growth. Mulch would be applied to the flat land on top of the banks.

Maintenance would be confined to removal of weed infestation and occasionally the re-placement of mulch if this is required.

Flood-land

Particularly in the lower reaches of the creek, there are areas which are inundated with even minor floods such as occur in most years.

As the creek reaches Bailey Street, and on to Barwon Heads Road, these flood-lands become more extensive.

The objective is to vegetate this lower-lying land with Swamp Gum, tea-trees, bottlebrushes, goodenia, lignum and tussocks to form an open woodland environment through which flood-waters can easily flow.

Maintenance would be confined to litter and invasive weed infestation removal.

Rising Land

The majority of the creek reserve consists of parkland through which cycle-pedestrian paths meander. There are picnic areas, seats and other furniture suitable for use in informal recreation. Most of the area is mowed regularly to minimise grass and weed growth.

The objective here is to further enhance the open parkland environment with scattered Manna Gums and copses of other shrubs and grasses.

Maintenance will continue as it is currently undertaken with some additional weed control around the trees and copses.
