privet – Dick's Creek Bush Regeneration

Working Bee – 17.08.2024

This is certainly the time of year for Bush regeneration. Good temperatures and soft soil make pulling out invasive weeds so much easier.

My intention was to get to the Bracken fern mound, close to the Sandpaper fig tree I cleared around last week. To do so though, I had to go through Site A and I really could not walk past it while it was in the state it was in.

While fishbone fern dominates this area, it is the privet that concerned me. Fishbone fern is easy to deal with while privet can develop deep roots which can result in a lot more work to remove them and they are well able to push out most other vegetation, especially when combined with lantana.

This is site A. It was once thick with lantana and then it was host to many bleeding heart trees. At present it has more fishbone fern than anything else.

This next photo shows site A after removing most of the privet and lantana along the back bank of site A. It is hard to see any improvement as there is still a wall of privet at the back of the area.

I did free some dianella of fishbone fern, seen here on the right, but for the most part, the fishbone fern has to wait for another day

I cleared site A of lantana and privet and then continued to do the same thing along the bank, past site A. The photo below is me looking back towards site A after finishing up for the day.

I was very happy to see this Poison peach tree (center of image) at the end of the day. I had seen this tree as a young sappling not long after doing some bush regen in the area. I would say it is now fully grown, standing around 5m tall. It joins my list of things to do as I see the lantana has started to encroach on it.

There were a few mystery plants I came across during the day. One vine was identified by a facebook group. Mystery plant – Clematis aristata

Same thing next week, weather permitting.

Working Bee and inspection – 10.08.2024

Perfect weather to do some bush regeneration yesterday.
No rain but the ground has had a good soaking so the weeds couldn’t put up much of a fight when being pulled out.
From my last few visits, I knew a lot more work was required to recover from the neglect of the last few years.

First step: An action plan. I moved around the reserve and tried to list the sections that required attention.

This stand of ginger lilly and palm grass continues to grow. It needs to be controlled while a native such as native ginger is allowed planted and encouraged.

These Sydney golden wattles were planted only four or five years ago but currently appear to be struggling or dead.
Though it is hard to see in this photo, there around about eight Cheese trees which were planted a few years ago.
They appear healthy but are clearly failing to make progress against the heavy clay soil.
I still hold hope that some of them will find a way to expand their roots to allow more growth.
The grass needs to be removed or thinned to allow new growth to have a chance.

Cheese trees and Sydney golden wattle are struggling

First falls is going well. A tree fern and some sandpaper figs are now growing out of the cliff face.

On the south bank, besides first fall, there is some clean up to be done. Fishbone fern is starting to appear, croften weed is still popping up and the privet tree has bounced back.
Still, it is mostly in good nick. An hour or so of work should have this area back in good order.

South bank besides the bottom of first fall.

On the south bank, just before the Fern wall, a section of bank is soil rather than the usual rock.
Palm grass has taken hold and needs to be addressed. This is true for the entire creek. I imagine an entire day will need to be
devoted to removing palm grass.

South bank besides First and Second falls

As a whole though, the section of creek between first and second falls is not all bad.
A lot of endemic ferns are going well, the Gahnia on the north bank is more established than ever and most of the visible trees
are meant to be there. The issues are the palm grass, the swedish ivy and the fishbone fern. Each of these will take quite some time to address

North bank between First and second falls

Fern wall, on the south bank between the first and second falls looks good but some bird nest ferns have gone ‘missing’.
We have had people steal bird nest ferns in the past and I suspect it has happened again. I can’t be sure until I locate previous images.
The ferns that are still there are going spectactular. The tree fern has shot up, as have other tree ferns at other locations.
Conditions must of been just right for this species.

Fern wall on south bank between first and second falls

Besides Fern wall though is the swedish ivy that is yet to be removed. Areas that have been done are still clear though so that is a good
sign that it can be fully removed.

At the top of Second fall, things look mostly ok. There is still privot, palm grass and fishbone fern to address but
it is good to see the weeds have not jumped back quickly into this area.

Fishbone fern is once again dominating the ledge on the north side of Second fall.
Luckily, the natives have a longer reach than the fishbone fern so are still able to catch the light they need.

Cabbage tree palm is looking good after some shading trees were removed from a nearby property.

Site A is still clear of lantana but is now covered in fishbone fern. Disappointingly,
something laid waste to the stand of bleeding hearts which were growing here. There is still a few but most are now dead.

This bank has always been dominated by fishbone fern but it has currently taken it up a notch
now that it is getting so much more light with the removal of some large trees at the top of the bank.

Simlarly for the bank behind 16 Green Valley Rd.

Hill above site A upto 16 Green Valley Rd

This photo shows some of the bleeding hearts that have been pushed over. Hopefully more will grow
when the fishbone fern is removed.

From site A, looking towards the creek at the rear of the reserve, it appears as if privet has taken over. Hopefully it is
not as bad as it looks…

From site A, looking down to the rear of Dick’s creek reserve

There is a stretch of poisoned lantana at 16 Green Valley Rd. I am not sure what the purpose is.

This area is kept clear by the property owners above.

Fern trees along the back of the reserve look to be doing well. However, the lower storey is once again dominated by undesireables such as lantana and ginger lilly.

Lots of privet in this area towards the creek as well.

A stretch of land is kept clear down to the creek by the property owner above. The land to the side of this ‘alley’ is
infested with privet and lantana.

I had previously cleared around a large sandpaper fig at this location. Lantana was once
again encroaching heavily on this tree and the area in general. I needed to clear the lantana just to get to the tree so I could start
clearing around it.

Lantana and privet encroaching on sandpaper fig that was previously freed

Around three or four years ago, the sandpaper fig tree had fallen over. It was disappointing at
the time but since then, the tree has continued to thrive and is still bearing fruit. This photo shows the roots have grown to accomodate
its new position.

At this point I had finally reached the base of the tree. My intention was to clear the area
around the tree so I could walk freely around it, but that ended up being too ambitious as some of the privet and tobacco trees were
too big to pull out by hand.

This photo shows new shoots rising vertically while the main trunk is now more horizontal. It looks
like this tree will be around for many years to come yet.

One positive discovery was finding this poison peach tree. There were also some young sapling nearby.
I was able to free them from the lantana which was starting to get on top of it. It is about three metres tall.

This poison peach tree and some younger saplings was covered in lantana. It is about three metres in height

Wile it is not clear, this photo shows the sandpaper fig tree. I was able to walk around it
(rather than climb) by the time I had finished. Some large privets had to be left for another time. I was happy with the result.

This was the sandpaper fig tree after clearing around it. It still looks chaotic but by the end it was free of lantana and privet

This shows the ‘dent’ in the wall of privet. I am mindful that any clearing like this invites foot
traffic from the kids in the neighbourhood. It will pay to start at the center of the sea of lantana near here and work towards the edges for this reason.

The area I cleared to get to the sandpaper fig tree.

Near the creek at the end of the reserve has become infested with privet but there are still
some natives doing well. For example, this cabbage tree palm…

A wall of privet…

On the side of the cleared strip, privet dominates.

But amongst it…

Unidentifed vine next to cleared strip. Pretty sure it is native but need it identified

Tree fern next to creek at rear of reserve is growing very quickly

After this point I went along my usual route along the creek back to the track that leads to site A but it was so infested with lantana and the privet it was a battle to move and taking any photos was not really an option. It is going to take a lot of time to get it back to the state I had it at a few years back.

Working Bee – 23.01.2022

Was able to get another 3 or so hours in this afternoon. I took the weedpuller down with me to help with some privet but in the end, I didn’t get to the section I intended to work on (nothing new there…).

Palm grass has been getting ignored for the last six months or so and it was showing. Multiple spots where it was getting far too healthy. So I tried the weedpuller out on the palm grass and surprisingly, it made easy work of it. I expect it depends on how soft the ground is but as it was, it made easy work of most of it (easier than a mattock at least). I dared not clear all of it in case it was holding the bank together but I did enough to keep the shade off the nearby cheese tree sapling.

I was disturbed to find the tree fern near first fall was in dire straights. I hope it makes it. It seems that removing the camphor laurel has just allowed too much light to reach it. Fingers crossed that it adjusts to having more light for a while.

Once again, I decided to help out the Gahnia by picking on the fishbone fern. Not removing all of the fishbone fern but rather, just thinning it out and breaking off any large fronds. It is a slow process but it seems to be working. I hope the area along the creek between first and second falls will end up being mostly Gahnia.

Another inspection at the top of 2nd falls shows the Swedish Ivy really taking off.

On the positive side, the area has a variety of desired species doing well

Including a first for Dick’s Creek, a Blueberry Ash.

I do need to address the Swedish Ivy issue but today I only got to the a couple of privet trees and some camphor laurels. A productive day though.

Working Bee – 09.01.2022

Had a chance to get some more done at Dick’s creek for the first time in the new year.

As always, I deviated away from my original target after noting some weeds on the way. On the lower west bank of first fall I noticed a healthy stand of Croften weed & mistflower.

Not surprising of course considering that these invasives dominated the spot a few years ago. It didn’t take long to do some maintenance to get rid of most of it. This area is doing well mostly. Native ferns and trees are growing stronger and the weeds are having a harder and harder time.

I videoed progress while I was there…

I took some video at ‘Site A’ and also after manually removing some lantana behind 16 Green Valley Rd. I took some more photos and video of an issue I have with lantana rafts taking too much space. I am convinced that most bush regeneration advice is aimed at large sites where rafts can be built and forgotten. However, as there so much lantana at Dick’s creek and the site is relatively small, I find those piles of dead lantana take up too much space so I have tried a few options to speed up the breakdown. Firstly, I was spreading out the dead branches rather than piling them. Normally this is not done as it is possible the branches will reroot but I take this into consideration and find that spreading out the branches is an improvement.

Another approach I have now had success with, is to pile green leafy weeds in with the raft when it is made. It keeps the moisture in contact with the dead branches and hence hastens the process. Key with both approaches is to reduce the size of the branches as much as possible.

Finally, I got to the back of the reserve, near the creek, where I intended to spend most of the time on. Privet is the main issue at this location. I found multiple native saplings taking off at this location so I ended up just trying to keep the privet away from these guys.

In this shot, the pittosporum can be seen. A lot of the surrounding privet has been pulled out and will soon die.

Here we can see a small Cheese tree and another small tree of that as of yet unidentified tree that appears to like the area.

Hopefully I can do more for these in future working bees as they are struggling against the privet.

Working Bee – 12.09.2021

A quick session today. Actually classified as exercise rather than bush regeneration 🙂

Once again, just pushing back on lantana. I came across a large sandpaper fig tree that I had previously freed up from lantana. It had since then, fallen over but it continues to thrive. It had once again started to provide structure for the surrounding lantana. I removed the offending lantana and also bits of privet.

Sandpaper fig after I had cleared off the lantana.

I will need to come back to this spot as there is various promising saplings which need defending.

Here is a summary video I did of the site after clearing the fig.

Working Bee – 27.02.2021

Dick’s Creek had a visit from the green team from the lake macquarie landcare resource center during the week. Many hands make light work and that was definitely the case on the day. Some good progress was made on the day despite delays due to rain. While there on the day I noticed some sections done previously had sprung back. Namely lantana and privet as usual. I have been quite taken back by the speed that everything is growing at present. Rain is great for all the plants, weeds included unfortunately.

Yesterday, I had a chance to get some guards around the Cheese saplings I planted a month or so ago.

Everything is looking super green at present. Maiden hair along the cliff face next to the first falls has never been so abundant.

Palm grass is looking a bit too healthy at various places along the creek. At placed, I need to consider erosion control. When the water flows fast, it takes anything that is loose down stream so sometimes it is just better to leave some weeds in place for this reason. Here is what I am describing…

Further along, I am pushing back the swedish Ivy as various ferns show up. Hopefully it is a case of slowly does it. Things are looking much better but it can all go backwards quickly if I don’t keep an eye on it.

A trail that I often used that leads from the second falls around to site A was enveloped by fishbone fern. Impressive. Annoying but still impressive. I cleared the trail. This video shows the area and also one of the areas done by the green team.

Also done by the the green team and I last Tuesday…

Continuing on from that section I cleared lantana and privet back down the creeks edge (which still needs some serious privet treatment).

Here is the summary of the day which I try to do for each working bee. It was a good day…

Fighting Fishbone Fern – 3hrs – 09.11.2019

Spring is here and the weather has been perfect to get some bush regeneration sorted.
My object was clear, remove the remaining lantana on the East bank that overhangs 2nd fall. I was doing this a few days back when I decided a final effort of at least a few hours. The object was not met. I never actually got to 2nd fall. Walking down the creek I came across infestation after infestation. Stuff that I just could not walk past.

Firstly, this sucker…

I had cut down this privet tree quite a while ago as other choices were limited and it was getting too large to ignore. However, as expected, it was doing its best to make a comeback. I couldn’t ignore it so I got in and finally dug it out. It was harder than usual due to the fact it had wedged itself between some bolders and rocks. Still, out it came so yay for that.

With my focus brought to privet, I decided I need to scope the size of the job to tack the privet between 1st and 2nd falls. I started walking along the East bank of the creek to look for any smaller privet I could pull out directly and determine how many larger privet trees needed to be dealt with. Privet is probably now the worst invasive tree in the creek as the other offenders have been beaten down. The most notable plant on the East bank though is Fishbone fern. Fishbone Fern is native to Australia but not to this region. It is clearly identified here as a weed by how strongly it dominates the area.

It is so numerous and prolific it has always been put off for another day. However, I stumbled onto a small outbreak of Bracken fern. I was most impressed that this Bracken Fern had somehow been able to take on the Fishbone fern. The Bracken Fern was still struggling though as it could barely be seen amongst the Fishbone so I got in and gave the Bracken Fern a bit of space and hopefully a bit more light.

Hopefully this will give it a chance to start spreading and push back the Fishbone fern somewhat.

As well as coming across a few new outbreaks of Bracken Fern, I was quite happy to see some Rasp Fern taking root further along the creek. Unfortuately it too was battling various weeds. I chopped down some privet as a temporary measure but it was need to be addressed. Small Rasp fern can be seen in the images below. It appears to have only come through after a weed was pushed back some by the landcare green team. I am uncertain about the name of that weed but I remember it was identified as originating from the african continent.

I was also a bit disturbed to find some fully grown privet trees which dominated certain sections of the upper canopy. A ‘privet attack’ is very much so needed. It will need to be a more permanant solution as well. That’ll either be pulling them out of the ground or using herbicide of some sort.

I didn’t get to my objective but it was a productive bush bash with some positive results coming through.
