Blackberry, Weed of National Significance ! This is a VERY LARGE Infestation, Several areas in this vicinity, each is 50-100m + long by 20-30 m wide. Whoever the Land owner is here ? Has IGNORED this infestation for many years. Adjacent to Sydney Federal Highway about 500 m from Gungahlin turnoff. Sensitive Location as lots of waterways with Excellent Frog Habitat here. Many Frogs are present judging by Loud Frog Chorus here.
Max, the (only) good news is perhaps that the frogs don't mind. It looks like the infestation is on private leased land. best to map using the Fieldmap/Collector app and get in contact with the ACT Biosecurity team. The photos seem to indicate that the infestation is on the declared grassy woodland ecological community.
Proposed for development; the weed infestation is the result of Strategic Neglect. Once critically endangered grassy ecological communities are degraded to a level where local natives have almost disappeared it can be bulldozed without the need to provide offset. If the Strategic Neglect is not sufficient to do the trick of degrading, the area can be used for storage, dumping, etc as we see in the Majura valley and in the Kenny area. The Kenny area was grassy woodland integrating into temperate grassland both critically endangered ecological communities under Commonwealth and ACT legislation.
Thanks Waltraud. Definitely agree with your comments of STRATEGIC NEGLECT. This site has some good Canopy of local species of Eucalypt trees remaining. However the ground and understory are almost completely taken over by Invasive weeds. This location was part of the Critically endangered Bailey's and Yellow Box woodlands. Very Sad to see it so (deliberately neglected and degraded). Local Landcare regulations are very Dysfunctional.
M, there is a proposal to develop. The process is currently at the stage where that developer proponent applies for a change of the Territory Plan from broad-acre to residential. If you see signs of neglect and / or abuse than you can be pretty sure the land is earmarked for development.
