Blackall Creek Riparian revegetation

Day's end

 Blackall Creek OnGround Works and Concept Plan Explanation (As at 28-5-2008)

To be read in conjunction with the Management Plan and concept map

Area

No.

Description and comments

Work to undertake

Completed Works and comments

1

Area 1 is a natural stand of Melaleuca ericifolia (Swamp Paperbark).

The stand would be a suitable area to eventually place bat/bird /possum boxes

Handspray Ivy and Bridal Creeper, hand weed, plant Swamp Paperbark around perimeter.

(Chase up nest boxes-Wendy Hayne?)

Area burnt, grass sprayed around the stand. The dead trunks and stems should be left. Protect suckering shoots (guard and stake?)

 

2

This area is adjacent to the newly re-installed drain. The ground has been excavated and compacted.

Little thought has been given to run-off.

Plant out with shrubs and Manna Gum. Spray Kikuyu and other weeds prior to planting.

Area cleared by others (WSC contractor)

There are concerns about introduced weeds in soil brought in!

3

This area was a washed out channel caused by poor road drainage (prior to flood events of 2007). It has been sculpted and rock placed around the edges to assist in water flow mitigation.

The drainage line has been heavily mass planted with wetland plants.

Maintenance -perimeter spray and hand weed. More sedge/rush planting will be required within and around the water run area.

Sedges, rushes and grasses planted. It is considered that the area will require further heavy plantings.

4

This area is a healthy stand of paperbark with clonal suckering taking place.

Hand spray blackberry and kikuyu. Hand weed between the sucker growth.

Area has been perimeter sprayed. Not to be burnt or surround planted.

4a.

A thin strip between the existing Paper barks and the track.

Plant local Gippsland Manna Gum

Area has been sprayed once

5

The rock poundage MUST be heavily planted and weed maintenance is essential. This is to help avert a disastrous erosion situation and to prevent an unsightly weed infestation.

Transplant Phragmites & plant Lomandra (200)

Melaleuca, Dodonaea, Acacia planted. The poundage holds water continually (mosquito breeding?) and appears to leak which in a heavy rain event will create an erosion break point! Some Phragmites has been planted and Typha seed has been dispersed in the pond.

6

A respite area for potential visitors.

The Ephemeral Wetland sign should be placed near the seats.

Plant flowering shrubs (Indigo, Grevillea near seats)

Seat made, area sprayed. Follow up spraying required. The seats may need to be pinned prior to a flood event.

7

This is the track for walkers and Landcare vehicles.

Track to be maintained (slash regularly)

Track defined, and slashed.

8

This is the creek crossing, which will link the town plantings to the top west area. It is important to allow recruitment of Phragmites australis and Typha to help bind the stream banks.

Build boardwalk/low bridge. Weed control & extra plantings.

Track defined and creek perimeter planted. Area sprayed (kikuyu will be a problem).

 

8a

 

 

 

 

 

 

9

 

 

This area is heavily weed infested and will require clearing (fire?) and replanting with species able to withstand flood events.

 

 

Area 9 borders the creek and will be an important area to mitigate flood effects. A number of vulnerable

Drainage lines will require preventative works, perhaps rock baskets (CMA?)

 

Spray, burn?, hand slash.

 

 

 

 

 

Spray, heavy sedge plantings as per 3 with Paperbark and Wattles to

complement the plantings

.

Nil

 

 

 

 

 

1st spray, Kikuyu will be a problem. Blackberry and Bridal

Creeper may be problematical.

It is important to encourage natural recruitment along banksides (Persicarea/Typha/

Phragmites/Juncus spp.) This area maybe an area for visitors to be able to observe the stream and environs.

10

A mixed planting of Lomandra longifolia (Mat Rush) and Melaleuca parvistaminea (Rough Myrtle Paperbark).

 

 

Maintain (spray, brushcut).

Further planting of Native grasses to be undertaken (1000+)

Sedges and shrubs planted. Weeds sprayed. Will require careful follow up sprays.

11

This area is below the paperback stand (1) and should be heavily planted.

Plant (E.viminalis ssp pryoriana)Manna Gum, Paperbark and (A.melanoxylon)Blackwood, respray

Area cleared and sprayed. Kikuyu will be a problem.

12

A flat flood area

Spray, more Wattles & sedges

First spray, some plants in

13

Area 13 is the area surrounding the Avon Landcare sign.

It is envisaged a planting of wildflowers and shrubs, similar to the Women’s Garden will be undertaken in this area. A bordered garden area will be built to provide an accompaniment to the adjacent parkland.

First spray,- will require a number of follow up sp[rays-due to heavy concentration of Kikuyu.

13a.

A steep bank needing further plantings

Continue bank planting

Area sprayed

14

The pathway area is steep and will require suitable steps for access to the top area.

Build steps

Ground shaped

15

This area describes the steep banks towards Niel St Drain

Replace trees on bank, spray &brushcut

Trees planted, some brush cutting done.

16

The area is the western side of Blackall Creek and will be boundary planted with a mix of Eucalypts, Wattles and Bursaria as a windbreak planting.

Burn Boxthorn, spray and slash. Prepare for approx. 200 trees along boundary as shelter/windbreak. Monitor for boxthorn recruitment.

Some Boxthorn burnt, area partially slashed.

17

The area is a natural stand of Leptospermum lanigera (Woolly Tea tree) and Paperbark, with Phragmites australis (Common Reed) interspersed

Handspray Blackberry and monitor for regrowrth of willows.

Nil- natural recruitment to be encouraged.

Seed collection and propagation to be undertaken for surrounding stream banks. Need for sensitive maintenance.

 

18

This area encompasses a steep embankment with a few natural flood terraces along the length (approx 400m)

There is natural vegetation along the length of the area, incl. Kunzea (may eventually need to be controlled. Monitor blackberry regrowth, plant shrubs, eventually cut out pines and apples. It is recommended that the wombats in the area be ALLOWED to remain undisturbed!!

CMA has sprayed Blackberry

19

Area 19 is a natural occurrence of reeds-Typha & Phragmites.

Allow to recruit. Handspray blackberry and monitor willows.

Nil.

20

Area 20 is a heavily weeded flat that has had some plantings. It is an area that should be made accessible for the public to approach the stream side.

To be sprayed spring & summer 2008 for Kikuyu control. Plant Autumn 2009.Plant riparian shrubs.

 

 

 

Some planting done-2006, misc species.

 

 

 

Comments and recommendations:

·         A significant weed problem Robinia psuedoacacia (Black Locust) exists on the western side of the Blackall Creek Project. The weed has formerly been thought to be Mimosa pigra (Mimosa).

·         Concerns are held with regard to the rock drain area (stability, effectiveness). The responsibility for repairs to the drain and the Avon Landcare Groups revegetation is an issue that requires clarification!

·         The Avon Landcare Group must commit to a long term weed maintenance plan in conjunction with the West Gippsland CMA and Wellington Shire Council. This is particularly important if the Blackall Creek Project is to embrace recreational community participation through use of walking tracks and strategic placement of interpretation boards.

·         Further funding will be essential for continued planting, track work and maintenance for the project.

·         Prevent recurrence of blackberry/willow infestation

 

 

Idea for Sign

 

Avon Landcare

Ephemeral Wetland Site

Areas that flood and dry are important components of stream systems, providing diverse and unique habitat for a wide variety of insects, amphibians, reptiles and birds.
