I was confused by this plant. It certainly looked prostrate, but had leaves with brown spots which I thought was a characteristic of P. decipiens. None of the other P prostrata that have been found have spotty leaves!. Could this be a hybrid? Plantnet only mentions blotches on P decipiens (note: No link to plantnet for P. prostrata)

Persicaria decipiens has pink flowers and is more erect, and is usually found near permanent water as well. I have seen a few spots on the leaves for P. prostrata, but yours certainly is unusually spotty!

I found a photo on the ANBG site that has a few spotty leaves on P. prostrata, but not as many or as definite as the ones I photographed.

I couldn't help but notice that these and other photos are from the STEP block. I was reading the latest STEP newsletter today and saw some of your photos in there too. Have you been a member for long?

I have only been volunteering at STEP (and a member) since January, but have taken an interest in the group since its inception. I planted trees at STEP several years ago and have recently been helping to plant additional rushes, trees and shrubs around the wetland area (where I Frogwatch as well). The understorey plantings are looking very good (and all labelled) so well worth a visit.

I have been a member since STEP began, but have not been involved in the on ground work. I designed their logo for them. I hope one day STEP will become part of CNMap. I think it would be mutually beneficial.

I don't see why STEP should not be part of CNMap. The volunteers are included as part of Parkcare. The main difference is that most of the plants have been planted and not occurred naturally although they are all local. Maybe someone should discuss this with David Shorthouse the current coordinator of STEP

Hi guys, I'll follow up. I just read about STEP here http://step.asn.au/. All we'd need is the lat/long boundaries of the STEP block(s) and we can certainly get them up and running on CNM. I'll chat with Michael M more about it, he may have some more info around this.

You probably don't even need the lat/long info. It is forest 20 at the arboretum and it is possible to see the boundaries on the Google map above. It is bounded by a dirt road on 2 sides, a dyke between the temporary car park and block 20 and an allee between the Mesa oak forest and Forest 20. I can send you a Google map with the boundaries if required.

Cool thanks Galah. Michael M is onto it, putting together a shape file for me which we'll load in...

It would be useful if people commented on whether their sighting is 'planted' or coming back naturally as a consequence of the STEP project.

Good idea Mike... Ok guys, STEP and also the other Arboretum woodland block are both up: http://canberranaturemap.org/Community/NaturePark/143 and http://canberranaturemap.org/Community/NaturePark/142 Look forward to your feedback. Cheers Aaron.

Both of the maps look good. Thanks for doing this so quickly. There is also another piece of natural woodland at the Arboretum - Forest 2 - don't know if you want to include this as well. I probably won't go to look for plants there until the spring.

Thanks Galah. Will check out the other Forest 2. PS we also need a moderator for these blocks. Are you interested?

I could probably mange these areas. I may be the only person taken an interest in Forest 2 and the additional woodland for a while.

Hi Galah681. Thanks for your recent contributions. You have been installed as moderator for STEP's Forest 20, and the Woodland too.
