Zone 3: what’s going to happen there?

As we reported on our website last month, DSE has released the draft Fire Operations Plan for consultation. Although FOBIF has many concerns about the plan, and urges members to consult it and make a submission based on their local knowledge, we are urging you here to focus on proposed burns in Zone 3. These are burns generally relatively remote from settlement, and have in the past on paper been devised principally for ecological reasons.

The draft DSE Fire Operations Plan proposes several significant Zone 3 burns in our region in the next three years. The stated purpose of these exercises is: ‘to provide an irregular mosaic of areas of fuel reduction which will complement works in adjacent fire management zones and can assist in ecological resilience and forest regeneration.’ All burns are proposed for Spring between now and 2015:

Brown's Gully, Castlemaine Diggings NHP: FOBIF is getting mixed messages about how much of this bush is to be burned, and what attention if any will be paid to ecological values. It's up to the public to urge that DSE follow its own policies on Zone 3 burns.

Muckleford: Dunn’s Reef—257.6 ha [CAS 11] and A Frame Tk—319.9 ha  [CAS 12]

Maldon: Donkey Farm Tk—188.4 ha [CAS 10].  Nuggettys –274.7 ha [CAS 5]

Chewton: Railway Dam—193.4 ha [CAS 13]

Taradale: Plantation Tk –151.7 ha [CAS 17] Carnell Rd—225 ha [CAS 14]

Glenluce: Amanda’s Tk 409.3 ha [CAS 15]

To find maps of these proposed burns, go to the DSE website:

FOBIF and other interested groups were told by DSE in July that the objective in zone 3 is to aim at ‘at least 20%’ of burn coverage: that is, to burn 20+% of each named parcel, perhaps up to 35%. However, we have been told recently by fire operatives that they aim to burn 50% of each zone 3 parcel [This confirms our observations of past Zone 3 burns, some of which go much higher than 50%]. Further, although the DSE Code of Practice and the stated aim of the burn as we have quoted it above requires a clear ecological perspective on the burn, we have been reliably informed that the intention of these exercises is purely fuel reduction.

It is important that pressure be exerted on DSE to implement its own stated policy regarding the use of fire for ecological purposes.

You can make a difference by writing a short submission to DSE by August 31:

The view from St Arnaud

The St Arnaud Field Naturalists Club has made a detailed submission to DSE regarding the draft fire operations plan for the St Arnaud area. Below we reprint part of the covering letter attached to the submission. Although of course conditions vary from district to district, readers will notice that many of the concerns expressed here overlap with our own [Please note that ‘ecological management zones’ have now been renamed ‘landscape management zones’. DSE signage is sometimes out of date]:

‘…We note that all areas listed [for burning] are labelled “Ecological Management Zone”; we believe this to be misleading as there is no reason to manage the ecology of the areas by burning, ie., there are no fire-dependant species. Burning will produce a simplification of the understorey remaining after 15 years of intense drought and heavy grazing by kangaroos. Already, long-term (more than a decade)studies by both our group and Monash University researchers show that habitat degradation and simplification(loss of species) have resulted in a decline in the number of bird species using our bush areas as well as a serious decline in the number of birds within all species. This decline continues despite two years of above average rainfall. Further loss of the integrity of our Park and allied reserves will mean a further decline in species.

Little Monster?

The beautiful creature pictured below is an early instar caterpillar, from the genus Doratifera, probably Doratifera oxleyi. These moths are commonly called cup moths. It was found in suspended by a thread in an area of severely damaged bushland in the Diggings Park this week.

Cup moth caterpillar: It’s less than a centimetre long, and you can’t deny it’s pretty— but don’t touch it! We’re not sure if it’s the creature that’s eating our bushland. Photo: Bronwyn Silver, 14 August 2012

Cup moths Cup moths ‘belong to a small group of moths that have unusual slug-like caterpillars that are often beautifully marked and coloured. They derive their name from the cup shaped cocoons made by the caterpillars when they pupate. There are several different species of cup moth that feed on eucalypts and other native plants. The caterpillars differ in colour, pattern and size but they all have the characteristic slug-like appearance with clusters of spines on their bodies. The spines can inflict a sharp and painful sting, rather like a nettle and the caterpillars are often known as ‘stingers’.  The stings may cause local inflammation if they touch bare skin.’ [ref: Department of Primary Industry, SA]

We mistakenly reported last week that the enormous damage inflicted on eucalypts in the south end of the Shire was caused by lerps. Now we believe that the damage is caused by a leaf miner of some sort, and have suspicions about the cup moth–but we’re not sure. Theories are invited.

Looking after a Yellow Box

As part of National Tree Day on the morning of 29 July, 15 volunteers planted 240 indigenous plants under the ancient Yellow Box tree at Chewton. Low plants, ground covers and shrubs were planted under the tree and larger shrubs including Rough, Hedge and Golden Wattles and Bushy Needlewoods were planted further away. A grant from Mount Alexander Shire was used to buy these plants from Frances Cincotta of Newstead Natives.

Although the main effort was put into planting, people also removed small bridal creeper plants that had survived last year’s eradication work by FOBIF. A few days after the planting several FOBIF members attacked the infestation of gorse on the bank between the Yellow Box tree and the Great Dividing Trail. We are hoping that future walkers will be able to enjoy this beautiful spot without being confronted with masses of gorse and bridal creeper. As well the understorey plants will promote the health of this magnificent tree.

Alex enthusiastically attacking the gorse.

Forests under attack from leaf miner

Visitors passing along the Porcupine Ridge Road in recent weeks have noticed that trees on both sides of the road, both in the National Heritage Park and the Upper Loddon State Forest, are looking extremely stressed, presenting a desolate sight.  The cause appears to be a plague of lerps. Such a plague usually reflects a decline in the number of woodland birds which normally feed on lerps. [SEE OUR AUGUST 16 REVISION OF THIS ASSESSMENT]

Distressed trees near the Helge Track: bush health is dependent on biodiversity, and low bird numbers suggest that we may be in trouble.

 

 

 

 

 

 

 

 

 

 

This decline is alarming from many points of view. The current condition of this bush is an indicator of the connection between biodiversity and forest health. Castlemaine Field Naturalists report that the ‘decline in bushland birds is alarming.’ Their

Lerp attack: the absence of woodland birds is not just a problem for bird watchers.

monthly bird counts at the Spring Gully/Fryerstown Road intersection reveal that the number of species seen, and the number in each species, have been declining for some time. The counts for 2012 are

FOBIF response to fire operations plans

The following is FOBIF’s draft submission on the Fire Operations Plan [see above]. Member feedback is invited:

GENERAL COMMENTS

1. We believe that as far as possible, burn areas be small: less than 100 ha. In zones 1 and 2, they should be smaller than 50 ha. In our opinion, this would make it easier for managers to pay close attention to ecological values, something hard or impossible with large hectare burns.

2. DSE should where possible integrate weed and fire management in the burn plans. We note that integration of weed management and bushfire control is part of the Mount Alexander municipal fire plan.

Middleton Creek, Castlemaine Diggings NHP: Common sense dictates that steep slopes should not be burned, and that important old trees not be destroyed.

 

 

 

 

 

 

 

 

 

 

 

3. In Zone 3 burns, unless it is possible to guarantee that burn cover will not exceed 20% [that is, unless it is possible to guarantee a genuine mosaic burn], and that vulnerable areas [eg, steep areas, or areas of particular interest, like large trees, creeksides etc] can be protected, we believe that managers should aim to burn precisely defined areas within the treatment zone. We would like to have access to the Zone 3 burn plans for our area.

4. Spring burns should be avoided.

Magic mountain

 

 

 

 

 

 

 

 

 

Saturday morning July 28 wasn’t an ideally warm day for crawling around the high points of Mount Alexander, but half a dozen members of FOBIF’s moss group had a pretty interesting time crawling around finding new species to pore over. This time of the year isn’t great for flora, but it’s perfect for mosses, which provide plenty of interest even when when you’re feeling a little, er, cold. The next foray will be in a month. Members interested in coming along should contact us at info@fobif.org.au

FOBIF's moss group at work. This has been an excellent season for mosses, and Mount Alexander is one of the best places to get an idea of their variety and beauty.

Mosaic burning research

The Box Ironbark experimental mosaic burning project is under way. The project is the joint responsibility of DSE, Parks Victoria and Latrobe and Deakin universities. Research in the project will be based around 16 planned mosaic burns of 100 ha each in the Heathcote Rushworth forest. Eight of the burns were conducted in Autumn last year, and eight in Spring. Half of them aimed at 35-50% burn coverage and half at 75-90%.

The project’s monitoring program focuses on questions like:

–How do different mosaic burns affect the composition of plant communities?

–Does burning stimulate germination of additional plant species from the soil seed store?

–Do mosaic burns cause changes in the density of tree stems in the forest?

–Are logs, stumps and areas of deep litter lost at disproportionate rates due to high flammability?

–Do planned burns alter the composition of woodland bird communities?

–How does fire affect the movements, foraging behaviour and breeding success of individual birds?

–Do burns result in an increase in the home range size of the Yellow-footed Antechinus?

–Do fires result in a loss of den sites for the Yellow-footed Antechinus?

You can get more details and keep abreast of news about this project by getting on the mailing list for its newsletter. Write to the project officer, Greg Holland at Deakin Uni: greg.holland@deakin.edu.au

FOBIF walk in Sandon

The July FOBIF walk was to Malcolm Fyffe’s property in Sandon. This was a much appreciated opportunity to visit a farming property with lush undulating pastures and spectacular views.

Malcolm gave running commentary on the history of the property. Glenwillow has been farmed by his family since the 1940s and after a career in teaching Malcolm took over management of the farm. Over the past few years assisted by Bush Tender funding he has been able to improve and rehabilitate the property by erecting fencing to keep out stock from existing vegetation and waterways. He has also worked on weed and pest control and undertaken strategic plantings.

The differences in soil and rainfall in this area which is to the south of Castlemaine have resulted in comparatively vigorous growth on common local plants such as coffee bush and hedge wattle.

Finds of particular interest were unusual fungi including some that were pink and bright red and a Striped Greenhood Pterostylis striata. These plants and other scenes from the day can be viewed in the slideshow below. The photos were taken by Noel Young, John Ellis and Bronwyn Silver.

FOBIF photo exhibition ends

Peron's Tree Frog--Litoria peronii. Photo by John Ellis

FOBIF’s Mamunya photo exhibition 2012, which ended last week, was the most successful yet. A record number of photos was sold, and we were pleased with the attention paid by the public to the notes attached to the photos. We’re particularly grateful to the kind soul who corrected our mistake the scientific name for Peron’s Tree Frog– an unaccountable error fortunately not repeated in the photo in our picture gallery.
