Fisheries Report No 14 - Wilson Inlet - A Seasonally Closed Western Australian South Coast Estuary, R C.J. Lenanton
Fisheries Report No 14 - Wilson Inlet - A Seasonally Closed Western Australian South Coast Estuary, R C.J. Lenanton
Fisheries Research Reports
Considerable conflict has existed for many years between professional fishing, recreational usage and development in the west and south coast estuaries of Western Australia. One of the areas where intense conflict exists is Wilson Inlet.
The Government's task of advising the various interests concerned in these conflicts has been difficult, due to the lack of knowledge of estuarine fauna and environment in relation to usage and development.
The objective of this report is to present a preliminary description of the Wilson Inlet environment, to record the history of netting closures in the Inlet, and to discuss the history of the …

Fisheries Report No 13 - Results Of A Biological Survey Of The Shire Of Kent, Western Australia, N. L. Mckenzie
Fisheries Research Reports
The Department of Fisheries and Fauna is responsible for the conservation of the native fauna in Western Australia. The main approach to this problem has been the creation of reserves for "The Conservation of Flora and Fauna". These reserves, known as "Wildlife Sanctuaries", are controlled by the Western Australian Wild Life Authority - a Statutory Authority serviced by the Department.
The object of the acquisition programme is to develop a reserve system which will include, as far as possible, a full and permanent cross-section of the State's native floral and faunal assemblages and, at the same time, provide for the …

Fisheries Report No 11 - The Fauna, Flora And Planned Usage Of The Dampier Archipelago, A. A. Burbidge, R. I. T. Prince
Fisheries Report No 11 - The Fauna, Flora And Planned Usage Of The Dampier Archipelago, A. A. Burbidge, R. I. T. Prince
Fisheries Research Reports
The Dampier Archipelago is a group of islands off the north west coast of Australia (20 20! - 20 45'S, 116 Cast . 117°E), first discovered by William Dampier in 1699 and subsequently named after him by the Baudin expedition of 1801. This name has since been applied by some authors to include all islands from Roebourne to North West Cape, including both Barrow Island and the Monte Bello Islands, but it is more correctly applied to those islands within a 30 mile radius of the town of Dampier.
Ir. recent times, three parties have visited the Archipelago and examined …

Fisheries Report No Vii (7) - Results Of A Biological Survey Of The Millstream Area, A. A. Burbidge Dr
Fisheries Report No Vii (7) - Results Of A Biological Survey Of The Millstream Area, A. A. Burbidge Dr
Fisheries Research Reports
Millstream has long been recognised as an unique and outstanding area, both scenically and from a biological aspect. The area of prime interest consists of a series of deep pools in the bed of the Fortescue River (about 15 miles long including Gregory Gorge) and the springs and streams which feed them. Most of the springs are in the sides of the river bed but one of the largest is about 1% miles to the south. This feeds a swift flowing stream running north into the river bed.
The first Europeans to see the area were the exploring party led …

Wildflowers Of The Stirling Range, Alexander S. George
Journal of the Department of Agriculture, Western Australia, Series 4
TWO hundred miles south-east of Perth, the Stirling Range rises abruptly from the surrounding plain. About forty miles long, it is a line of semi-isolated hills, rather than a continuous block.
There are many intriguing plants of diverse colour and form. Well over 400 species are known from the Range. A number of these are found no-where else, and some are restricted to one mountain.

Skeleton Weed, G R W Meadly
Journal of the Department of Agriculture, Western Australia, Series 4
SKELETON WEED—Australia's worst weed of cereal crops—was found for the first time in Western Australia last month.
The outbreak was reported to the Department of Agriculture by a Ballidu farmer who found an unknown weed on his property and suspected that it could be skeleton weed.
An immediate inspection was made and skeleton weed was found over about quarter of an acre in one paddock.

Collecting Plant Specimens. 1. Specimens For Identification, Robert Dunlop Royce
Journal of the Department of Agriculture, Western Australia, Series 4
PLANT NAMES and the naming of plant specimens are of fundamental importance in many branches of science, including agriculture.
To the farmer, too, accuracy in naming poisonous plants and weeds, as well as fodder and pasture species, can save much trouble and expense, and may be responsible for avoiding heavy stock losses.

Studies In The Mulga Pastoral Zone. 2. Some Aspects Of The Value Of The Mulga Scrub, D G. Wilcox
Studies In The Mulga Pastoral Zone. 2. Some Aspects Of The Value Of The Mulga Scrub, D G. Wilcox
Journal of the Department of Agriculture, Western Australia, Series 4
THE mulga pastoral zone is so named since most of its area is dominated by Mulga (Acacia aneura).
The mulga is found associated with shrubs and grasses in almost all plant habitats. In its various forms it can associate with spinifex (Triodia basedowi), Wandarrie Grasses (Danthonia, Eragostis and Eriachne spp.) and with low shrubs on flood plains, hills and breakaways. It may even attempt to become established in salty communities, though this is never completely successful.
The scene the area offers from its low hills is one of a succession of low undulations, occasionally scarred by creeks or breakaways and …
Trees Of Western Australia - The Grey Box, C A. Gardner
Trees Of Western Australia - The Grey Box, C A. Gardner
Journal of the Department of Agriculture, Western Australia, Series 3
In the grey box the rough bark extends to the ultimate branches, unlike that of the coolabah where the smaller branches are usually smooth. The grey box is the common tree of the basalt areas to the north of the King Leopold Range, but unlike the coolabah it is not found along the streams but is more typical of the stony hills and undulating country. Its occurrence is so closely connected there with basalt and andesite, that this particular soil type can at once be mapped by reference to the grey box trees.

Poison Plants Of Western Australia: The Thorn Apples (Datura Species), C A. Gardner, H W. Bennetts
Journal of the Department of Agriculture, Western Australia, Series 3
Many garden enthusiasts are familiar with a shrub or small tree known as the "Angel's Trumpet" or "Trumpet-flowered Brugmansia." Some nurserymen call it "Brugsmania." There is another garden favourite which does not appear to possess a common name but is an annual or perennial plant from one to four feet in height, of summer growth and carrying erect violet or white trumpet-shaped flowers succeeded by large bristly or prickly pods. Both these are species of Datura. Another species is native to Western Australia while four more are introduced noxious weeds.
Trees Of Western Australia— The Coolabah, C A. Gardner
Trees Of Western Australia— The Coolabah, C A. Gardner
Journal of the Department of Agriculture, Western Australia, Series 3
The coolabah and the grey box are two common tropical trees which closely resemble each other in bark, foliage and other characters, but which differ widely in their soil requirements and in their timbers. Both are numbered among the most valuable trees of the Kimberley district because of the strength and durability of their exceedingly hard timbers and their resistance to the ravages of the termite.

Trees Of Western Australia— Coral-Flowered Gum, C A. Gardner
Journal of the Department of Agriculture, Western Australia, Series 3
Among the more decorative small trees available for planting in the Eastern Agricultural Areas, there are few more suitable that Eucalyptus torquata. This tree, known also as the "Christmas Tree" of the Coolgardie and Dundas districts usually blooms during December, and its handsome drooping coral-pink blossoms make it a conspicuous object in the woodlands at that season of the year. It was first discovered by L. C. Webster near Coolgardie in 1901, on a stretch of stony dioritic country 25 miles in length and about a quarter of a mile in breadth. It is found at least as far south …
Trees Of Western Australia— White Mallee, C A. Gardner
Trees Of Western Australia— White Mallee, C A. Gardner
Journal of the Department of Agriculture, Western Australia, Series 3
This species is usually found in mallee form, growing from 10 to 18 feet tall, but may at times possess a single stem, and is thus a small tree. Both mallee and tree forms have characteristically a broad 'base or stock, so that frequently in the mallee forms the individual stems arise well above the soil level from a large domelike base. As a tree the stem may be as much as 18 inches in diameter. The species is characterised in the field by its white or pink bark which is covered throughout externally with a white smooth talc-like powder. …
Trees Of Western Australia— Lemon-Flowered Gum, C A. Gardner
Trees Of Western Australia— Lemon-Flowered Gum, C A. Gardner
Journal of the Department of Agriculture, Western Australia, Series 3
The Lemon-flowered Gum is one of the lesser-known trees of the Eastern Goldfields. Originally discovered by Richard Helms, botanist to the Elder Exploration Expedition, 60 miles to the south of Victoria Spring, in 1892, it was not rediscovered until specimens were collected by Henry Dean, consulting engineer for the Trans-Australian Railway, near Zanthus in 1909. In that year it received from Maiden, Government Botanist of New South Wales, the name which commemorates Bernard H. Woodward, then Director of the Museum and Art Gallery in Perth.

Trees Of Western Australia - Swamp Or Flat Topped Yate, Brown Mallet And Four-Winged Mallee, C A. Gardner
Journal of the Department of Agriculture, Western Australia, Series 3
The two trees described here under may be readily distinguished when growing as they differ considerably in their barks and general appearance and grow under different conditions, but in common with some other trees of the Southwest each has the mallee form, and the mallee forms are very difficult to distinguish.
Trees Of Western Australia - Gimlets And Pear Fruited Mallee, C A. Gardner
Trees Of Western Australia - Gimlets And Pear Fruited Mallee, C A. Gardner
Journal of the Department of Agriculture, Western Australia, Series 3
Next to the salmon gum, the gimlet tree is perhaps the best-known of the trees of the Eastern Agricultural Districts and the Eastern Goldfields. A thin reddish brown bark, and a fluted or spirally-twisted trunk (especially in the young trees), distinguish at a- glance the gimlet trees or fluted gums from all other Eucalyptus trees. This bark has a thin outer layer which when removed reveals a sappy pale green, inner bark, and sometimes this inner green bark is exposed when the trees shed their reddish-brown outer bark towards the end of summer.
