Byenup Hill Catchment Report : Carlecatup Catchment Land Conservation District, Justin Hardy Aug 1993

Byenup Hill Catchment Report : Carlecatup Catchment Land Conservation District, Justin Hardy

Agriculture reports

The Byenup Hill Catchment is situated just west of Graham's Well which was a major watering point for early travellers. The area was first settled around 1890 and some of the names associated with early settlement are Hinchey, Dennis, Bilney, Holding and Gabette. Clearing with axes was a slow process and most of the sheep were run in the bush in areas free from poison bush. A reasonable number of trees were left standing and the last clearing was done in the 1980's. The first signs of salt appeared in the 1930's and advanced with increased clearing.


Flora Of The Quindalup Dunes Between Swan And Irwin Rivers, Western Australia, E A. Griffin Jun 1993

Flora Of The Quindalup Dunes Between Swan And Irwin Rivers, Western Australia, E A. Griffin

Research Reports

A study designed to determine the variation in the composition of the vegetation on the coastal Holocenes and deposits between Perth and Geraldton is described. The study was based on 545 sites at which descriptions of the geology, landform, soil and vegetation and a complete list of flora were made.The floristic composition of these sites varied considerably. Numerical classification showed some quite distinct communities and others which seemed part of a multi-dimensional continuum. Several factors appeared to be instrumental in the variation in composition. Landforms (incipient fore dunes, dunes or plains) were a major factor. So too were proximity to …

Hard Setting Grey Clays, colloquially termed Moort Clays by the Central South Coast farmers of Western Australia, fall into the typical class of Sunday soils (i.e. too dry to sow a crop on Saturday and too wet on Monday) - acknowledgment that these soils can be difficult to manage. The local soil name derives from the dominant endemic vegetation growing on this soil (Eucalyptus platypus ssp) usually with no competing understory vegetation. Moort clays are most often found on mid to upper valley slopes and depending on parent material and pedogenesis are often alkaline (sometimes acidic), hard setting, sometimes cracking, …
