i've noticed Polygonum/Persicaria species, some of which are
knotweeds in Oz English plant common names, growing predomininantly
in some compacted soils or soils which are otherwise 'hard' for many
plants to grow in.
In biological science there is an important hypothesis, as all
science is hypothesis, called the "Regeneration Niche", now while
niche theories may not be too real or really important for humans or
in nature, the theory of each plant species each having specialised
more or less limited conditions in which it's seeds germinate is
empirically more than just a theory.
Knotweeds, most of which are introduced to Oz from outside Oz and
unnecessarily so, in my experience are very effective germinators on
hardened soil surfaces or generally compacted ground. They may then
serve to break up more or less gradually that surface or soil
compaction allowing plants with different seed germination
requirements to germinate and grow by themselves.
Compaction is a very important human-initiated degradation which has
often been overlooked and makes a huge difference in plant quality
and species of plant that regenerate.
Land around my house has now after 2-3 years since cattle and
tractors were nearly completely taken off, and in spite of being
covered where cleared of bush by disclimax (diversity suppressing -
eaten & regulated normally African mega fauna) African Kikuyu grass
up to 3-4 ft high, now, there are native wattle species, valuable
food, regenerating by themselves.
The Black Wattle is exactly the same species that Fukuoka san uses/d
in his orchard as an introduction from Oz, it is endemic to Oz, and
i also have very beautiful, W.E.-valuable-wood, rich-seed-food,
Blackwood wattle coming up in this 1 metre thick rank grass now.
This is the opposite to what local grazier farmers initially said -
'that nothing would grow in the Kik' if i didn't graze cattle on
Many more plant species are or will come up in it too, and
compaction by hard hoofed W.E.-society-derived-agriculture animals
like cattle is one of the main reasons why the bush didn't come back
quicker initially that they were removed - there was a lag time of 2
or so years for the Kik' and the living soil itself to aerate itself
enough for taller plant to be able to survive and grow through the
Gloria did you read the article that i linked to some weeks ago

It is particularly down to earth and informative as to how to and
who to link up with to regenerate many of the different types of
landscapes irrespective of the emphasis of their human-use from down
to earth integrated practice and philosophy. Some other articles in
this publication are also very to the point, and many are about or
include urban areas.

From the very partial - the most conservative parts of the Oz
scientific community, the Commonwalth Scientific & Industrial
Research Organisation (CSIRO), comes the following 2 wake-ups,
admissions and actions for us in Oz:
- Compaction is a substantial factor in these Oz-wide W.E.
agriculture problems mentioned below.
Making farming sustainable - Lyndal Reading
Traditional farming is devastating the environment and causing
extensive salinity. It's the claim, not from a hysterical greenie,
but from CSIRO. Despite all the talk about sustainable agriculture,
Dr John Williams from CSIRO Land and Water says what farmers
currently do is simply not sustainable at all. He says its very hard
to find agricultural land use at the moment that can have a water
balance that does not leak water into the underground system, a
potential hazard for salinity levels. He says the ones that do have
an economic cost. He says one of the major causes to salinity of the
Murray is the changed water balance from the Mallee. He says deep
rooted perennials and shrubs in the agricultural landscape, breeding
our way out of it and using more native species are part of the

"No more leaky agriculture, says CSIRO scientist"
Wednesday, 27 October 1999
Australia needs a complete rethink on the nation's agricultural
resources and how we use them, warned CSIRO Land and Water Deputy
Chief Dr John Williams, at The Regional Australia Summit being held
According to the organisers, the summit is being held to bring
together business and community to take a hard look at the problems
facing the bush. Dr Williams' ideas are part of a background paper.
"The search for farming systems and land use patterns that do not
harm the environment is urgent. It must form a central plank in any
strategy for regional development in Australia," he said.
"Our European style of agriculture is mining the reservoirs of
carbon and nutrients in our soils, as well as leaking water,
nutrients and pesticides to groundwater, rivers and wetlands," Dr
Williams says. "It is the very leaky nature of Australian agro-
ecosystems that lies at the root of nearly all land and water
Rural Australia already has begun the process of change with
programs such as Landcare and more attention to sustainable
practice. But Dr Williams believes there needs to be a national
strategic research effort to design alternative land use practices
which can support rural communities.
"A key strategic focus is to build productive agro-ecosystems that
leak much less water, nutrient and carbon to the landscape in which
they are located."
"Farm forestry, new agricultural production systems and restoration
of native vegetation present opportunities to restructure the
landscape with vegetation that has a similar water-use pattern to
the original bushland. The use of native plants and animals may form
an increasing part of rural production. Bush foods, native
wildflowers, oils, pharmaceuticals and industrial chemicals are all
receiving increasing attention."
