Requirements to make a naturalistic substrate and habitat

Postby kingofnobbys » Thu Jul 12, 2018 4:55 am

Very common for people (including Australian bearded dragon keepers and breeders - most of who never venture into the interior to see for themselves) to assume the natural habitat of central and rankins bearded dragons looks like the Sahara or the sandy deserts in middle east or in the high plains of the USA (in the Rocky's rain shadow). This is wrong . Very little of the natural range bearded dragons are found in is actually genuine sandy desert (maybe 5%).

This will help put the range of habitats in the natural range of central bearded dragons (and Rankins) into context .

Image

Very little of it is sandy (like the Sahara) and none of it calcium sands.

Mostly the soil is ancient highly weathered clays .... known as bull dust. Dry it's like concrete.

No fuel => sandy desert and bluffs.

So to address this misconception here are some scientific facts about the vegetation, climate and natural "soils" bearded dragons have evolved to thrive on , the studies are centred around Alice Springs which is close to central beardie GZ.

This is typical of flat landscape that is found in the natural habitat of bearded dragons :
Image
The grass is a tough arid resistant grass called spinifex , the soils are highly weathered sandy clays, often rich in iron but poor in organic content.
There are also drought tolerant trees , mainly acacia and mallee


You might get a good look using sandstone boulders (I'm sure you can find these at any garden centre as lots of people buy these to add borders around flower beds and to landscape, like some of these https://anlscape.com.au/Products/sandst ... e-flagging
and https://anlscape.com.au/Products/sandst ... -bush-rock.

As to material to go under these and around them - that's tougher - maybe clay mixed mixed red ochre , mix with water and mold to shape and let air dry …. must be completely air dried (not baked) this will be close to the soil centrals encounter in their natural range.

Here is scientific information about what you SHOULD be trying to reproduce to have the enclosure as authentic as possible.
For those who want bioactive substrates : sorry - not likely to work using substrates that will be close as possible to authentic.

scroll to page p50 and you'll see several examples of the natural habitat in the natural range of central bearded dragons.

Red stained tilers grout between the boulders and slabs is probably the best bet....lay it fill gaps and let it set and harden , very durable and impervious.

Good info. I wanted to confirm this and tack on with some photos I took in the Adelaide Hills while I was doing some lighting research (and looking for wild dragons). This is in the southern part of their range but they are found in the hills on the outskirts of the city and also in the vineyards nearby. The soil is a hard packed red clay with rocks and grass and leaf litter all over.

* this one isn't mine. It was posted by Kay Brothers in McLaren Vale. Wild dragon in their rosemary. They also reported that one got picked up in their harvester. He was OK but upset about it.

Been there , nice area , and I've seen wild centrals when I was there (on holiday), even saw some in local parks in Adelaide as well as Water Dragons.

I don't know how familiar you are with the hills on the outskirts of town. The top two pictures are from Morialta park. The third one is in Cleland park just a bit below the summit of Mt Lofty. It's cool you got to see them in the wild. I didn't see any when I was there. The parks around CBD are pretty great though. I saw lots of wild parrots.

I've been to all those places, even the more hard to get to places requiring a 4x4 ( drove in on some difficult fire trails and stock routes (places the usual tourist never sees and where sometimes only 3 wheels are touching the ground occasionally) , and some long hikes) …. yes it's parrot paradise there !
Been to places where wild life never saw a human before and are more curious about you than scared of you.
