I have often been left with large piles of dead lantana after landcare working bees. Current recommendations is to leave those piles on site to breakdown in time. However, Dick’s creek is (well, it was…) a small reserve with a big lantana infestation. Those piles take up a lot of space that I would prefer to see being used by native flora. Those lantana piles take a long time to break down. I have heard people suggest twelve months is long enough for it all to disappear but I have seen piles remain mostly intact for years (see video below).
Following landcare rules makes the situation more challenging. It can’t be burnt, we can’t bring machinery on site to process it, it can’t be taken off-site, no building compost heaps etc. I have often felt at loggerheads with this issue…
As any gardener would know, a compost will only work when there is enough moisture and I think this explains my issue with lantana. As long as the remaining debris stays strong enough to keep it suspended above the ground and hence able to stay dry, it takes a long time to break down. I needed to get the debris into something that will keep it wet. So, what I am trying at present and what I show in the video below, is an experiment to see if combining dead lantana with more fleshy green leafy weeds will hasten the composting process. I am hoping it will.
I picked a few locations, ‘Site A’ being one of them. I tried to brake down the lantana as much as possible by standing on it and breaking it up with my hands. I then raked nearby tard/wandering willy (there is no shortage unfrotunately) into the pile. Hopefully, with some rain, it will break down and more area will become available for the flora that is meant to be there.
Fingers cross this will work so I will have an approach I can use for any other lantana infestations.
Here are some videos I took to describe the issue and the approach I am using…
Not really a working bee on this day but I did remove some privet on the west side at the top 2nd fall and removed some fishbone fern on the East side.
This video shows the East side of the creek at the top of 2nd falls. It has a small native olive tree clinging to life by growing mostly horizontally from the cliff edge. It has always been forced out by the fishbone ferns growing from the edge.
Fishbone fern has an impressive ability to create its own root structure. It can end up in the most unlikely of places.
I partly removed the fishbone fern to hopefully encourage some other native flora and to hopefully aid the growth of the native olive tree.
Between ‘Site A’ and the creek, I often referred to as ‘Site A extension’. It has been around a year since I did that work and this video shows the progress at that location. There is a large pile of dead lantana which I want to remove somehow and there is some weeds that have popped back up but largely, it is pretty good. In particular, I liked seeing the hairy clerodendrum budding. I have never seen it flower before.
After taking that video I inspected the west bank of the creek. Under No.2’s property. I don’t normally go over the west bank as I decided quite a while ago to focus on the East side first. The west bank was a mixture of good and bad. There are many natives so we can be confident that the seed bank is in good health. It will be a matter of removing the weeds. In particular, privet along the creek is dominating.
One interesting find was this staghorn fern:
It is the first one I had noticed on the reserve. There was also a large birdnest fern nearby which was good to see.
In summary, the west side is in mostly good condition but the privet will need to be treated. That won’t be as easy as it sounds because getting around was very difficult. Lots of barbwire vine and sizeable cliff edge along the bank makes traversing the area quite difficult.
I got a few hours of lantana bashing in on Saturday…
Mostly I focused on the lantana near the creek towards the rear of the reserve. I had cleared the creek edge previously and this led to some natives taking off. The usual bleeding hearts and sandpaper figs but also a lilly pilly amongst others. Still, I hadn’t moved far from the edge of the creek and the lantana was threatening a return. I put an end to that…
That spot was chockers with lantana but now those sandpaper fig saplings towards the center of the photo should have a good headstart.
I am having to consider where people will walk when an area is cleared. There appears to be enough people going through the reserve now to make a difference. Not a bad thing but something to keep in mind in case some more fragile plants could be damanged. I left some privet and debris to deter people using this area. Easily removed when the saplings become big enough to not be easily walked on.
Here is a summary video I took at the end of the day. Poor quality unfortunately…
That fern tree that can be seen in the video is another win as well. More of those, yes please.
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.
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.
While trekking through the bush in Dudley, Lake Macquarie, I noticed a young poison peach tree (Trema tomentosa) near some lantana (Lantana camara). I took advantage of the situation by comparing the two for future reference.
Leaf wise, they are quite alike but with poison peach leaves being more elongated. They main notable difference when they are growing upright from the ground (not that common for lantana) is the leaf arrangement. Opposite for lantana and alternate for poison peach.
Life has been getting in the way of Dick’s creek landcare lately but I should be able to get back into it soon.
First thing though is to have a look and reassess where I am at and what has priority. To do that I did a site inspection which I videoed as I went along…
There is a mixture of good and bad. Some natives are going strong, some weeds are still dominating various areas. Most notably for me is the creek edge after second fall towards the back of the reserve. I need to go along and remove the young privet and lantana before it can get established. I am keen to get into it.
It was a late start for Sunday’s working bee but it still turned out to be a productive day.
Mist flower is popping up again in numbers. Grrrr. I am not sure if that one will ever completely disappear. It seems fairly well established in the seedbank. Some of the plants grow in very difficult to access locations so they do not get removed as quickly as I would prefer.
One win I noticed on the weekend is the false bracken fern on the East bank after first fall. I had noticed a few struggling bracken ferns amongst the fishbone fern about twelve months ago. I cleared around those and they expanded and I cleared around that and it has expanded again. It appears the false bracken fern is very capable at taking on the fishbone fern. when it gets a chance.
Another win was a dead camphor laurel tree which the green team had dealt with in their last visit. A bunch of privet was also killed via glyphosate. I typically avoid using herbicides but then, I tend to end up with situations as seen at ‘Glen’s alley’ which has a troubling number of privet saplings and trees springing up.
My original intention was to start on the area in the photo above but instead, I learned a large, dead, rotting tree had finally fallen. I had noticed it a long time ago and was amazed it was still standing given the amount of rot at the base. Finally it has come down.
Rather than let the lantana close in on the vacated space, I thought I would open up the area for the nearby sandpaper fig trees which are sure to appreciate the extra light.
I have a long list of areas that need attention so I will need to get to work a bit earlier next week. That privet beckons me…
It was a productive day. After working on a small amount of palm grass before first fall, I decided to finally help out the gardia growing between the first and second falls. Gardia has been growing well but it is still having to compete with a lot of fishbone fern and some ginger lilly.
Here it is before trying to thin out the fishbone fern…
You can see in the image that the gardia (the tall grass seen in the center of the image), is getting above the fishbone fern but it is not very numerous. As I started weeding the fishbone fern I found a lot more gardia that was just too small to get to the light and hence were not looking very healthy.
After spending half an hour or so removing fishbone fern, the gardia now has a lot more space to expand and young shoots should now be able to grow above the fern. The image below shows the spot after weeding. I tried to use some judgement as to how much I should remove. I would not want to allow erosion to take place. Fast flowing water can cover the area if there is heavy rain.
A hairy clarodendrum I walk past when going to site A is being attached by these guys…
It was a straight forward lantana and privet removal after this point. No photos to show because I was too tired afterwards. I starting an area requiring maintenance but then expanded on that to clear a good section under ‘Site A’.
One concern is a lot of plants showing a brown discolouration. I am hoping it has to do with the extra light coming through after a large gum was removed in a nearby residence but that does not seem to match. I noticed it on some bleeding hearts and most notably, on the giant tree fern along the creek after second falls. Hopefully it is not a big deal but it is a concern at present. Might need to ask the experts at lakemac landcare.
Last week’s successful attack on lantana motivated me to do the same thing again this time. However, as is often the way, walking to the desired location is full of distractions that were too hard to ignore.
Just off the road, at the entrance of the reserve, buffalo grass dominates the area. Scurvy weed seems to give it a run for its money but it has a long way to go before it could ever take this nasty grass on. Here is an example of what I am referring to…
So before descending to the gully after first falls, I did some minor maintenance. I pushed back the grass and removed the mist flower that was bothering any of the blue flax lilly or scurvy weed. Unfortunately, some spots are quite risky to reach. They will have to wait until I determine a safer way to continue.
This was before doing some weeding. See if you can spot the blue flax lilly.
One positive I noticed on the way to my selected target was a section of scurvy weed doing battle with wandering jew and swedish ivy. I gave it a helping hand by clearing a square metre or so around it. Hopefully it takes the opportunity to expand.
On the left, the undesirable swedish ivy. On the right, the almighty scurvy weed (and probably some wandering willy as well unfortunately).
Higher up is dominated by wandering willy. I intend to see how a rake goes with it.
I moved along the west bank between the first and second falls. Anywhere I saw a native being crowded out, I cleared around it. It still all looks very messy but I have to accept, it is a gradual process.
Still, looking back, upto the first falls, it is a pretty sight, even with all the weeds still dominating the area.
Another win…I believe it is a birdnest fern just above second falls.
After taking this photo I found another half a dozen on the other side. Looking good!
Finally, I got to the site I intended on in the first place. After a good couple of hours, I had cleared another good section of lantana that was crowding out various natives (Sandpaper fig in particular).
One other native I am seeing more of is the wombat berry vine. After asking for an id, I have discovered the narrow leaved vine in this picture is Geitonoplesium Cymosum, otherwise known as scrambling lilly. Good to see more natives springing up.
Next week I intend on doing the same. Attacking the lantana under site A (behind No.14 Grn Val Rd). Anywhere I find some natives gets priority and it does seem there are many natives struggling to stay alive.
