The President's Words:
With the year half over we seem to be finding more working bee sites rather than less. Some of our more recent ones have reinforced the need to not only follow up but frequently. We are at least getting to many sites before flowering and seed set but the speed of regeneration is something to behold. Thankfully the extra work being done by contractors has eased the pressure but large areas of the park still remain unvisited for long periods of time.
The following is an extract from InDaily, an
“Three times a year, the Department of Environment and Natural Resources puts on an event called Stirring the Possum, a panel discussion that looks at environment-related subjects. The importance of connecting with nature for our sense of wellbeing and happiness seemed the perfect Stirring the Possum topic for the most recent discussion, which was held on Tuesday night.” (22 May).
Well some of our Chief Executive’s utterances certainly agitated the marsupial for me; read on and see if your wombat is whisked.
“I want kids to be able to ride their mountain bikes across our metropolitan parks. Not on walking trails but on the fire tracks and vehicle tracks that we don’t let them ride on now. Because I don’t think that makes any sense”.
Well perhaps it would make sense if he had read the Management Plans for the Conservation Parks for which he is responsible. These statements actively undermine both Rangers and Friends efforts to improve biodiversity and heighten public awareness through LOW impact measures and initiatives. Another point worth noting is that the only walking tracks in Scott Creek CP (and many other parks) are fire tracks and vehicle tracks, so sharing these tracks would be unavoidable.
InDaily continues- He (Holmes) said that along with the change in public mood, politicians were becoming less willing to support or fund parks. “I’m not talking about in my backyard, I’m talking about across
“Holmes said he wanted his department, which is responsible for managing SA’s national and metropolitan parks, to open up parks for the public to use without restriction ”.
Doesn’t this directly contradict what he’s just said above? Looking after Parks by encouraging erosion and collisions with people who actually enjoy WALKING through remnant vegetation. I am also curious as to what “without restriction” encompasses.
Further remarks include, “The organisation is trying to turn itself around to face people. If you’re not part of community, if you’re not working with community, you’re not doing your job.”
Does this job include compromising what is left of our natural environment for the sake of attracting people who can’t be bothered walking through it and actually experiencing the natural world quietly and peacefully? Colin Malcolm, Friends of Onkaparinga, asks the question in their latest newsletter as to who thought it a good idea to hold a car rally through
Specious arguments generated for a quick publicity grab, do nothing to further or foster a genuine and lasting understanding as to why it is important to value the natural world. The perception that nature exists solely for humans to exploit and it is somehow “selfish” to try and preserve intact, what little is left, no doubt gains traction with those who would only visit a park if off road driving and cycling is permitted. I am yet to be convinced someone travelling downhill at 60kph in Scott Creek CP or any other park is taking in or appreciating what surrounds them. Perhaps a more valuable contribution to the debate would have been; how do we dispel these perceptions and try to instill a lasting understanding of the value of what has been gifted to us?
Below is a call to arms some of you might be interested in- I will be going, if anyone wants a lift.

Controlled Burning In Conservation Parks:
The question of controlled burns in parks is something which has been coming to the fore in the last couple of years.
DEH Response to questions raised re Derwentia Gully Burn
I would like to raise a few points about the Scott Ck A13 burn. The proposed site is a tract of very high quality intact remnant vegetation. This is due in no small part to the efforts of the Friends Group which has spent over fifteen years eradicating erica, boneseed, olive, briar and blackberry. Several plants of high conservation significance also occur here.
There are also several patches of the MLR Uncommon Rubus parvifolius, Native raspberry.
We have planted several Derwentia, grown from seed from the original find, in another creek line in the proposed burn site not far from the Logania saxitalis. Did your pre-burn ramble survey pick up all these species?
No, the pre-burn ramble survey did not detect either Logania saxatilis or Veronica gracilis but did pick up both Derwentia (Veronica derwentiana) and Rubus parvifolius. Of these four species only one (Veronica derwentiana) is in the database so it would be good to pass records for the other three species on to the Biodiversity Conservation Unit for entry into BDBSA. If this data has been passed on to DENR it hasn't made its way into the database for some reason - not sure why.
Do you know their response to fire?
Logania saxatilis: prolific resprouter based on observations at Sturt Gorge etc
Rubus parvifolius: has been killed by 100% scorch in one study and survived 100% scorch via root suckers in other studies (vital attribute data)
Veronica derwentiana: survives 100% scorch via root suckers (vital attribute data)
Veronica gracilis: no data but suspected to be in the same category as V. derwentiana
As discussed on site, at this stage our plan is to exclude main drainage line and lower slopes so expect we will not be attempting to burn areas supporting these species. I have to get Tim or Ian out on site to assess whether this is feasible and will keep you in the loop on that.
We have all the waypoints for these species and have passed them on to DENR but it would be advisable to check that your information is up to date. Much of the terrain is steep-very steep.
We are at a loss as to why this burn needs to occur at all as,
Based on my observations the other day I think that the areas of relatively long unburnt heathy woodland/heathland would respond very well to fire. There will be some temporary displacement of flora and fauna but this will be followed by a period of regeneration and higher productivity. I am concerned that some Messmate that are already stressed may by impacted, however, fire will likely initiate recruitment of this species which is desirable. I am less comfortable with the idea of burning the gum woodlands associated with the main drainage line as these areas of higher natural fertility and available moisture will be very vulnerable to weed invasion, particularly where there is a seed bank of fire responsive species and in open areas where annual grasses/herbs etc may increase in abundance. As discussed, my aim is to exclude what I consider to be the areas most susceptible to weed invasion/re-invasion.
It is very difficult and arguably not as high a priority (in comparison to sedentary/terrestrial species) to accommodate highly vagile/wide ranging species such as YTBC at an individual burn scale. Based on my own observations fire creates an immediate boon for this species and they exploit the area straight away hitting the cones that the fire has opened up (I watched them do this at Hardy's Scrub a few months ago). I accept that this area will offer limited or no summer feeding and therefore breeding resources for this species for several years but following that I expect it will be higher in producitvity than it is at the moment, ie as H. carinata enters into its reproductive prime. I believe the feeding requirements of YTBC are accommodated in the Ecological Fire Management Guidelines and as long as we ensure that we are maintaining a significant proportion of habitat >10 years post fire in a given landscape; which the guidelines dictate we will, then feeding resources for this species will be maintained and potentially enhanced. If there is no feeding habitat at this location this species has the ability to move to areas that do support such habitat. There are areas that are more productive than others and there will inevitably be temporary displacement of pairs of YTBC but I am more concerned about less mobile fauna species, weed management and fire sensitive flora in this particular case. If we know of old trees supporting hollows then we should identify these and protect them prior to and during burning as this important resource cannot regenerate or be replaced.
I expect that most of the weedy perennial grasses (Dactylis, Phalaris, Piptatheum etc) will not gain much of a foothold in the lateritized soils of the ridgelines and upper slopes. I agree that the drainage lines and gullys in particular are vulnerable to invasion by weedy annual and perennial grasses but we are planning on excluding these areas as a result of our inspection and conversations.
As discussed in my earlier email, the
I have had some discussion with Ian about this and he has provided the following:
As discussed above, I do think that the long unburnt areas of heathy woodland/forest and heath will respond well to fire based on our observations of similar habitat elsewhere.
Much food for thought in the above!
Since our last report, we have not been able to hold a session, due to inclement weather. After all, it IS winter, but there were a day or so on our scheduled weekends, where we might have been able to operate. It is something we have to play by ear.
It is Annual Re;porting Time to
The most important development, however, is that we were successful in obtaining a grant of $4500 from the Norman Wettenhall Trust to finance the detailed statistical study of our 18 years of banding data in the Park. The work is being done by Elizabeth Campbell, who, with husband Ewan and wee bairn Hamish, spent a couple of years with us, before returning to Scotland, where Ewan is doing important research on the Veroa mite, a parasite of honey bees. Liz is an experienced biological statistician, and the internet means we can forward data very easily. We hope this work will lead to some serious publication.
