No doubt making the most of over-time rates, this morning (Sunday) the NPWS lit up six hundred hectares in the Murrah Flora Reserve. According to the Rural Fire Service it is not a planned burn and the ‘Fires near me” map suggests the fire is in the Mumbulla section of the reserve. However, the 50 kilometer smoke plume is actually emanating from an area some 15 kilometers north of the RFS location, in the Cuttagee catchment.
As indicated in the photo below, at a corner of Murrah River road, it is difficult to describe the burn ‘patchy’. Rather, it appears to be quite a hot burn, consuming all ground cover in this location. While a visit in a few days will be required, I expect the fire will kill many of the forest oaks in the area and scorch the canopies of eucalyptus, particularly regrowth trees.
While some of us have become accustomed to forest mismanagement, the fact that this burn comes so soon after the report on Cuttagee catchment, is a little disturbing. Is this the NPWS’s management response to the dozens of erosion points identified in the catchment report? If so, where is the scientific evidence confirming burning will not exacerbate these erosion problems?
Then there is the so-called Murrah Reserve steering committee, allegedly established to facilitate community consultation and draw up another interim management plan. There has been no information from this committee, but if it agrees with the burn, it seems reasonable to assume ESFM is clearly not a consideration.
If one were looking for advice on forest management, the tablelands, where 2,000 square kilometers of eucalyptus woodland has died, may be a better option. In particular a document titled ‘Introducing some key management principles for restoring Box Gum Grassy Woodlands’ (Stol, J., 2016).
A quote from the paper indicates ” . . . Australia has largest truffle diversity of any continent with approx.1,500 – 2,000 species of an estimated 5000 spp
Eucalypts and many other members of the Myrtaceae are highly dependent on mycorrhiza formation for survival and growth.
Mycorrhizal fungi assist plants to repel parasitic organisms, obtain limiting soil nutrients, and ameliorate adverse soil conditions and severe climatic conditions by improving water relations
sites that have been cleared for grazing or degraded may be depleted of these important fungi.
The paper raises the question – “Truffle presence was found by Stol and Trappe (2010) to be negligible in paddock trees. Are high nutrient levels, damage to the network of fine roots near surface and resulting lack of truffles one of the less recognised background issues contributing to dieback?
In addition ‘Truffles need good soil moisture and leaf litter (ie. ‘mulch’)’ and logically the native species to spread their spores. If we are to believe the NPWS forests don’t need truffles or animals.
Both of them can’t be right.
