Smutta’s Track management burn

Smutta’s track, near Irishtown in the Castlemaine Diggings NHP, was burned by DSE in Autumn as part of the Bendigo Fire Protection Plan. The bush at the time was quite damp, so much so that we wondered at the point of the burning exercise. DSE are under severe political pressure, however, to ‘treat’ a target area of bushland with  burning, and it was no surprise that the operation went ahead.

As expected, the effect was very patchy. It’s hard to see its value as a fuel reduction exercise, though it may have some interesting ecological effects, given the excellent conditions for regrowth in the area.

We were extremely disappointed by two aspects of this operation, however.

First: we had advised DSE that there are some big old trees in this zone which should be protected from fire. Although there was some raking around larger trees, we were surprised and disappointed by the probable destruction of a veteran red box right on Hunter’s Track, on the Salter’s Creek side. We measured this tree at about 125 cm diameter at breast height. and as far as we can tell it was  a candidate for the title of biggest tree in the zone [see pic].

Hunters Tk, Castlemaine Diggings NHP: this tree probably won't survive the management burn. It might survive, but it’s taken a tremendous hit.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Its survival is doubtful.

After the burn off

FOBIF members have made several visits to the south end of the Diggings Park to monitor the effects of a very severe management burn conducted near the Wewak track in Autumn last year. On our latest visit, on February 7, we came to the following tentative conclusions:

1. Recovery of species has been good. Good rain has provided excellent recovery conditions, and we will report on the detailed monitoring of the area by Castlemaine Field Naturalists in due course, as well as DSE monitoring, if any. There has been an outbreak of thistles, a lot of which we’ve pulled out and taken away, and dandelions, possibly because of the large areas of bare earth created. Continue reading

It’s pretty, but it’s a weed

Ian Higgins identified this flower as a Gladiolus specie, probably G.undulatus. It is a weed that several FOBIF members found growing in great numbers beside a roadside in Sutton Grange. Unfortunately, as in the case of GazaniasGladiolus undulatus, it is still sold in nurseries.

Apart from their effect on bushland, weeds cost Australian agriculture $4 billion a year in decreased productivity and management costs. 65% are escapes from gardens and parks (Ref: www.weeds.gov.au). For more information and discussion about the impact of weeds on our bushlands see the Natural Newstead site.
