Michael, I was told that dead pines are hosts to wasps that then kill other trees, which would be a bad idea near commercial forests. Do you have any information?

Frilling of large pines is hard work due to the thick bark
Mike I think the wasp you refer to is the introduced woodwask Sirex which was recorded in the A.C.T. in 1989 according to R. H. Eldridge and E .E. Taylor (1998), see
http://www.dpi.nsw.gov.au/__data/assets/pdf_file/0005/390290/Sirex-Woodwasp-A-Pest-of-Pine-in-NSW.pdf
I'm not aware whether it has been detected in the Majura pines; I certainly have not seen signs of sirex infestations in the many wildlings that I've frilled in the nature reserve (and frankly I wouldn't care). According to the above article managing a healthy plantation is the best prevention of sirex infestation.

Thanks Waltraud. I was planning to make more use of the NZ technique of drilling and poisoning used successfully in the Marlborough Sounds. We can't afford the spot spraying by helicopter that has to be used in some areas.

I asked Neal Cooper, Senior Manager, Fire, Forest and Road Units (Parks and Conservation Service) for comment. Neal's comments below indicate that we should avoid using this method of control, where we can. We don't want to replace one pest with another.
"Frilling of pine trees on any large scale and then poisoning is certainly not ideal – this is the exact method we use to set up select 10 tree Sirex trap tree plots in the forest so that we can then inoculate the billet and sterilise the young wasps. In SA in the late 1980’s they had a severe outbreak of Sirex wasp which built to such large numbers on the drought stressed trees that they then starting infecting and killing live trees. We have an obligation as a commercial grower to control Sirex wasp so that numbers do not build up in our region threatening the multimillion dollar timber industry in the ACT and in the adjoining NSW. ACT has an active Sirex control programme where we inoculate billets from select trees every year with a nematode that feeds on the Sirex larvae. In addition the standing dead trees will attract Iots bark beetles which is another pest that we are obligated under legislation to control."

Sounds like we need a control plan for Isaacs Ridge as the wildings are spreading.

Could be a good project to apply for an Environment Grant for to employ some one to fell wildlings with a chainsaw - could also tackle other large woody weeds

If they are small cut with a saw, below last branch twirl, if large then we are able to use reticulated saws and if to large for that then I think we need to get assistance from PCS and./or apply for environmental grants to employ qualified contractors to fell trees.

Okay, thanks for the advice Michael. I think I've dealt with most wildlings already on the west slope. If I find the gps coordinates of those larger frilled pines of a similar size to the one featured here, should I forward them to PCS so that they can chainsaw them?

I think you should talk to your area ranger or the Phillip Selmes replacement (though Phil is un-replaceable) and see if they can have a program of tackling bigger pine wildlings over time - If you use collector I would put the large pines in that.
