Right, so we seem to be having a big euc seedling year here again. It’s been a few years since this happened. I’ve got baby redgums (E. camaldulensis) coming up in the veggie patch, pots sitting around the place, and in the mulch. I’m pretty certain they mostly originate from the very large, very old (possibly a couple of hundred years) tree in the backyard.

I know the eucs will drop seed after fire. Do they just build up a burden and eventually have a big drop every 5 or something years if there is no fire? I don’t really know how to find this out.

E. camaldulensis drops seed every year. They only germinate when there is enough water about.

The amount of seed they drop is reliant upon growing conditions. Red Gum can drop more than half of it’s branches over many bad seasons and replace the whole lot in one flood year.

As regards fires, all Eucalypt seeds can improve germination rates if heated. The germination rate increases with the level of heating.

That’s generally the way it works for many Australian plant species but no real need for bushfires simply to grow redgums. Our summers are hot enough for that.

The water levels are a bit below average this year. We had to conserve tank water for a bit some months ago. There was a veritable rain of seed though.

Last time this happened I potted up a few seedlings for the local regeneration project. I wonder if they want them again.

If you have a place to get rid of them it is worth potting them up.
It is about when the water is there. At the optimum time. Eucalyptus seed will come up like lawn and as they days dry out more and more and more die. The eventual result is that maybe one in several thousand makes it.

Some laboratory germination responses of the seeds of river red gum, Eucalyptus camaldulensis Dehn. Syn. Eucalyptus rostrata Schlecht
RJ Grose and WJ Zimmer

Australian Journal of Botany 6(2) 129 – 153
Published: 1958

CSIRO

A method for sampling from bulked eucalypt seed for germination tests, and a special technique for testing germination of these seeds in Petri dishes are described.

The seeds of Eucalyptus camaldulensis Dehn. will germinate both at constant and at alternating temperatures. They germinate best at a constant temperature of about 95°F.

The seeds require light for satisfactory germination. The light requirements of all seed-lots tested were satisfied by 8 hours of light daily at a constant temperature of 95°F. Light requirements are least at temperatures close to 95°F. There is an interaction between light and temperature and the requirement for light is reduced as the temperature is increased. Stratification also reduces the requirement for light in germination.

Thirty-one different lots of seeds have been studied. It has been shown that no relationship exists between environmental conditions of the locality of collection and optimum conditions for germination.

Thank you. Do you know if they produce different amounts of seeds at different times? Do they have some sort of cycle of some years or something? Some years we seem to have a lot more seed raining down than others. Perhaps that is temperature dependent too. I have so many “gumnuts” this year it is like a gravel overlay on the garden beds under the big tree.

I think that might be the case. I used to count the viable seed from various eucalypts and they would vary tremendously.

I probably should see if I can date when this happened last time and keep a note somewhere to see what time scale we are looking at for the big seed drops.

When I was counting the eucalypts seed, Eucalyptus camaldulensis seed was so fine that I could not tell what was the seed and what was the packing, which illustrates that each seed capsule contains a lot of seed and if I were you I would not try to count the seedlings, but just go on the overall germination.

I was thinking either non-Eucalypt Myrtaceae, or Eucalypt species with a low concentration of flammable oils.

Oil glands in the leaves are a characteristic of Myrtaceae spp, so all are inflammable to varying degrees.

According to our firefighters at our fire in 1996, they knew when the teatree swamp area caught and went up “Like the sun rising”.

That’s an apt description.

Let’s face it. There are very few plants that may resist burning longer than others. Australia’s Myrtaceae are not in that group.

Yes I’m sure anyone near paperbark swamplands during the recent fires on the north east coast can tell tales.

Hakea salicifolia is “fire resistant”. I had a hedge of it at Hawkesdale. But it’s not a tree. Ours were pruned by the yellowtail cockies every year.

So are the saltbushes which are on the top of the list in the link you posted.

As for the Maireana group which are also on that list. They will burn but slowly. You can boil a billy if you can find enough bluebush to stoke it but you’ll never boil a billy with old man saltbush.

and of those on the list, there are maybe three or four of the wattles that may make the size of tree one would want for carbon storage and possible timber harvesting and a couple of Myoporum species. The rest is all shrubby or groundcover. Not that these aren’t useful for carbon storage and fire resistance.

Oh, none of them are trees? Apart from white cedar


“White Cedar is a native Australian plant. It is considered as a weed in the south-eastern United States of America. While it is native in large parts of northern and eastern Australia, the species has also become naturalised outside of its range in many states, and is especially invasive in the Northern Territory and Western Australia. White Cedar can easily invade and naturalise in both disturbed and undisturbed areas. The plant is capable of producing large amount of bird-dispersed seeds, thus enabling it to colonise an area if left unchecked”

For a fire resistant native tree suitable for carbon capture – that’s excellent news.

Good.

White cedar is prone to infestation by cedar moth that can walk. Not suitable for close plantings. Need to be a fair distance apart.

Fire retardant if they aren’t choked up with a lot of old hard to rot down dead bits.

Thanks. We have a lot of them & the crowns get burnt off but they recover well.

White cedar is prone to infestation by cedar moth that can walk. Not suitable for close plantings. Need to be a fair distance apart.

Spotted gum are a good source of power poles but are restricted in soils capable of supporting them. Some grevillea are capable of also being used for timber but you are going to need a few centuries.
Wattles are probably the best bet. Because not only are many fire resistant, they also are great recolonisers after fires.
Kurrajong need their own space. Always did and always will.
