Water

Forty five millimetres of rain fell at the Castlemaine Prison over the two days September 9 and 10. After good winter rains [63 mls in June, 73 mls in July and 63 in August] the streams were ready to run, and they did.

Fire

DELWP seems to be expanding and varying its community consultation processes on fire. A ‘listening post’ was conducted by fire officers in Castlemaine on Saturday; and last Wednesday representatives of the Castlemaine Field Naturalists toured the district with the Department’s Paul Bates and Alison Jeavons to look at issues to do with fire and biodiversity .

Wednesday’s tour took in Wattle Flat, recently mulched areas in Chewton, and the Fryers Ridge.

The Ridge is set for a brilliant wildflower season, with displays already quite spectacular along the Ridge Road. The Fryers Ridge is a special part of this region, and it’s encouraging that the DELWP managers expressed an interest in incorporating Field Naturalist quadrat surveys into their planning processes. FOBIF was stunned last year to be told by local managers that they didn’t attach any particular importance to the ridge, because there aren’t rare or endangered species there. We have hopes now that this attitude may change.

The results of management fire are often unpredictable. Sometimes they provoke profuse regeneration, sometimes they are depressingly destructive, causing erosion, spreading weeds, and knocking out vulnerable species. These outcomes should be more predictable: if fire operations were conducted with more detailed knowledge of the special requirements of each area, they could be much less damaging. For this reason, excursions like that held on Wednesday are to be welcomed.

Wetland Plant ID

There are still some places available in the October 2016 Wetland Identification Course run by wetland expert, Damien Cook, and facilitator, Elaine Bayes. You can find out all about it by clicking on the image above.

Damien and Elaine are also leading our next FOBIF walk on September 18. The walk will take in Chewton’s highest mountain, ‘The Monk’, and Doug Ralph’s favourite long term unburnt bush near Eureka Mine.

Yes! It’s spring!

…And there are plenty of reasons to get out into the bush. Here are a couple:

Oh no! It’s spring!

Is this the best [that is, worst] year ever for the Oxalis weed? Since autumn we’ve seen the dense mats seem to get denser, to spread more widely, and to cover areas the weed’s never been strong in before. And now that it’s spring, those pretty yellow flowers seem to be everywhere.

Oxalis: among other things, it is, or should be, a challenge to fire managers

Oxalis: among other things, it is, or should be, a challenge to fire managers

There are 800 species of Oxalis world wide, including six that are native to Australia: we have two in our region—O. exilis [Shady Wood Sorrel] and O. perrenans [Grasslands wood sorrel: it’s the host plant for the Grasslands Copper butterfly]. The commonest local species is the introduced—and very feral—Soursob [Pes caprae]. It was introduced into this country in 1839 as a garden ornamental, a fact which adds a bit more weight to Tim Lowe’s claim [in Feral Future] that gardeners have done more harm to our environment than miners…

Any gardener will tell you Oxalis is hard to control. According to a 2012 DSE report, it’s also likely to increase in threat after fire, its bulbs allowing it to spread into bare ground. This, we hope, will be in fire managers’ minds when they’re conducting reduction burns in areas where Oxalis is already rampant [the proposed burn on Mount Tarrengower, for example].

Historic places report on the way

The Victorian Environmental Assessment Council (VEAC) will submit the Final Report on its Historic Places Investigation to the Minister for Energy, Environment and Climate Change on Wednesday 31 August 2016, rather later than originally planned.  The report will be publicly released on Wednesday 7 September and will be made available on that day at www.veac.vic.gov.au.

Readers will recall FOBIF made a critical submission to the draft report in December last year. We’ll be curious to see if any of our criticisms have resulted in changes to the document.

Two information sessions on the report will be held not long after its release. One is in Melbourne. The other is in Chewton on Friday 9 September from 10:30 am to 11:30 am at the Chewton Senior Citizens Centre, 201 Main Road/Pyrenees Highway, Chewton (Car park access off Mount Street).

If you want to attend, you need to register with VEAC by phone [1800 134 803 (Free call outside Melbourne)] or email:  veac@delwp.vic.gov.au

The State Government will give its response to the report within six months.

Undeterred by a bit of mist

Some of the Sunday’s walkers

A small group braved low temperatures, threatening cloud and persistent drizzle on Sunday for FOBIF’s August walk in Walmer. The weather looked worse than it really was, however, and the walk proved a pleasant stroll through mist barely strong enough to dampen the face. What’s more, leader Paul Hampton organised things superbly so that the last half hour was in brilliant sunshine: and only as walkers got into their cars at the very end did the skies open for a bit of a downpour.

The thick mist did obscure some of the brilliant views to be had from the hills in this part of Muckleford, but there was plenty to see close to hand:  Leopard Orchids, Caladenias, fields of Early Nancy, Hovea in flower, and carpets of moss and coral lichen. Paul also provided some fascinating insights into the social and ecological history of the area.

September’s walk will be a ramble on The Monk, led by Elaine Bayes and  Damien Cook. Check the walks program for details.

What’s eating our red gums?

For some months now, local Red Gums, especially around Mount Alexander, have been looking pretty bedraggled, attacked by some leaf eating insect we’ve been unable to identify. It seems to prefer only Red Gums: many Australians are unable to tell eucalypt species apart, but our insects are pretty good at it.

Green Lane Sutton Grange, August 7: The trees on the left are Candlebarks, whose foliage is untouched. The others are Red Gums, in dire condition from leaf attack.

Any suggestions about what the culprit is would be welcome. Infestations of Red Gums are pretty common, but this one looks more drastic than most.

Part of our problem is that the Red Gum is a generous host. A 2002 experiment found over 450 insect species in the canopies of just two trees near the Murray River! (You can find this info and a million other fascinating things in Flooded forest and desert creek, ecology and history of the River Red Gum, by Matthew Coloff–it’s in the Goldfields library system). So presumably there are several hundred suspects in this assault case…

Red gum leaves: trees of this species have been looking stressed for some months throughout the region.

Fire monitoring abandoned before it’s begun

As we have previously reported, funding for the very worthy Box Ironbark mosaic burning project has been ceased. But we had been led to believe that this all too brief project would be continued in some reduced way by DELWP staff who could monitor a restricted range of post fire effects.

This hope is now gone. We’ve been informed that no further monitoring is planned–DELWP doesn’t have the staff to do it.

This well designed project lasted only two unusually wet years, and obviously needed further work to give its findings solid credibility. A depressingly familiar pattern is being repeated. There isn’t enough money to run land management properly: so DELWP fire operations will continue to be run without serious, detailed knowledge of their ecological effects.
