A group of young Southern Blue Gum SBG recruits. The photos show: 1) foliage; 2) part of the group inside nature reserve with the parent tree in the background (outside nature reserve) and lower parts of a Blakely's Red Gum (inside nature reserve) on the right hand side of the photo; 3) another part of the group (photo taken from inside nature reserve bit further north of 1); and 4) the group photographed from outside nature reserve with a mature Blakely's Red Gum on the right hand side of the photo. From FoMM's experience with SBG planted at Valour Park that borders nature reserve I'd suggest to tackle early when the trees are too young to produce fruits. The SBG grow vigorously in the lower grassy woodland if allowed and may out-compete local Blakely's Red Gum which is one of the dominant tree species of the endangered grassy woodland here on the slopes of Mt Ainslie Majura complex. People without experience may have difficulties to sort out young SBG and local Blakely's Red Gum once the SBG spreads further. I suggest to tackle the young SBG now and keep an eye on recruits for the next 100 years.

Yep tackle now - I expect it is mature Blue-gums that are considered of some value perhaps because they are prime Gang-gang food - but Gangs-gangs are very adaptable eaters so I don't think it should be an issue.

Cheers Michael Mulvaney

thanks Michael
I need to get permission from Parks because a Mt Ainslie Weeder told me that PCS don't like them being removed - perhaps I misunderstood her. And yes, Gang-gangs are very adaptable reg food not to say opportunistic in their choice :-)
