Geographe Bay Catchment Natural Resource Atlas, Sarah Weaving

All other publications

The Geographe Bay Catchment Atlas is one of a series of Natural Resource Atlases covering the agricultural region of Western Australia. The purpose of the Atlas is to provide data for people in local communities who manage or have an interest in natural resources. It is now realised that the various components of the land interact with each other and therefore need to be managed together. This Atlas is intended to present natural resource and land information in an accessible way to people of the area. It may act as a focus for catchment planning and provide a starting point …

Report On Degradation In The Southern River / Wungong Catchment. Perth, Western Australia, Brian Lloyd

Natural resources published reports

A five day field survey of degradation in the Southern River/Wungong Catchment revealed several areas of concern. Key concerns are:

- Erosion and Sedimentation

Various forms of water erosion were present that cumulatively, would probably have a significant effect on the water quality of the Canning (and Swan) River. Much of the water erosion results from the installation and maintenance of infrastructure and developments, e.g. roads, subdivisions, stormwater drains etc. Reviewing standard practices, raising of awareness of consequences of erosion and training in urban erosion and sediment control techniques is recommended. Wind erosion is also an issue on the sands …

An Inventory And Condition Survey Of The Sandstone-Yalgoo-Paynes Find Area, Western Australia, A L. Payne, A M E Van Vreeswyk, K A. Leighton, H J. Pringle, P Hennig

Technical Bulletins

The inventory and condition survey of the Sandstone-Yalgoo-Paynes Find area, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 1992 and 1993, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the area’s natural resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed covers about …

Resource Use In The Trinational Sangha River Region Of Equatorial Africa: Histories, Knowledge Forms, And Institutions, Heather E. Eves, Rebecca Hardin, Stephanie Rupp

Yale School of the Environment Bulletin Series

This volume is based on an international conference, “Natural Resource Use Relations in the Trinational Sangha River Region of the Northwest Congo Basin,” held at Yale University in September 1997. In recognition of the bilingual context in which conservation occurs in the three countries of the Sangha region — Cameroon, Central African Republic, and Congo — all sessions of the conference were conducted simultaneously in French and English. This publication, which is a complete rendering of the conference papers and discussion sessions, is available in its entirety in both French and English.

Yuna Farm Improvement Group - Conservation Farm Planning Manual, Mike Clarke, Cecilia Mcconnell, Nancye Gannaway

Natural resources published reports

A landcare group formed on Tuesday, 30 June 1998 due to growing concern about land degradation. The main interests and objectives of the group where discuss and were outlined as follows:

1. Wind Erosion

2. Soil Acidity

3. Soil Degradation

4. Remnant Vegetation Decline

5. Tree Placement and Survival

6. Oil Mallees

7. Water Erosion

8. Non Wetting Soils

9. Salinity

10. Waterlogging

The first step toward addressing these issues was to organise two workshops with Mike Clarke, Cecilia McConnell and Nancye Gannaway from Agriculture Western Australia. The first workshop was held on the 4/8/98 and the second on the …

Bulletin 4333 - Furrow Sowing On Water Repellent Soils, Paul Blackwell, Grant Morrow

Bulletins 4000 -

This Bulletin discusses the benefits that furrow sowing brings to crop growth and production on water repellent sand, based on research and farm observations in Western Australian. By understanding the benefits and risks of several key processes, producers can better evaluate the potential role of furrow sowing in combating water repellency. This is true whether one is using direct drilling, no-till (narrow points or discs) or zero till (single, double or triple disc openers) methods.

Sem Analysis Of Quartz Sand Grain Surface Textures Indicates Alluvial/Colluvial Origin Of The Quaternary "Glacial" Boulder Clays At Huangshan (Yellow Mountain), East-Central China, P. E. Helland, Pei-Hua Huang, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Geomorphic features and Pleistocene deposits on Huangshan have been attributed to glaciation. Recent reassessment questions this interpretation. As part of the reassessment, quartz sand grains from deposits identified as glacial boulder clays (till composed of boulders in a clay or silt matrix) were analyzed by scanning electron microscope for evidence of their sedimentary history. Surface textures found on the boulder-clay grains were compared with those on grains with known sedimentary histories including glacial, grus, colluvial, and alluvial grains. The analysis shows that the grains lack typical glacial textures. The surface textures present indicate a complex history. Non-uniformly weathered grain surfaces …

Histomorphological Responses Of Red Shiner (Cyprinella Lutrensis) To Atrazine, Terbufos, And Their Mixture, Ibrahim A. Messaad

School of Natural Resources: Dissertations, Theses, and Student Research

Alterations of normal histomorphology of fish tissues, behavior, and thermal tolerance are recognized by environmental toxicologists and fish biologists as powerful tools indicating diverse biochemical and physiological changes. Toxicity of atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine), terbufos (S-(((1,1-dimethyl-ethyl)thio)methyl)O,O-diethyl phosphorodithioate), and their mixture to red shiner (Cyprinella lutrensis) at 23$\sp\circ$C and 30$\sp\circ$C was investigated in 14-d bioassays after 14-d acclimation. During the bioassays, fish behavior, indications of toxicosis, and external anomalies were observed. After the bioassays, the critical thermal maximum (CTM) was determined. Fish also were preserved for examinations of gill, liver, and kidney tissues using scanning electron microscopy (SEM) and light microscopy (LM). SEM …

Bulletin 4329 - Environmental Hazards Of Farming In Western Australia, Greg Hamilton, Ian Foster, Philip M. Goulding

Bulletins 4000 -

This Bulletin is one of a series on crop establishment practices which minimise soil disturbance and improve stubble retention. In partnership with primary producers, Agriculture Western Australia 1s focussed on improved and profitable farming which conserves or improves the quality of the State's soil resources.

Agricultural land in Western Australia is naturally fragile and susceptible to degradation. Salinity and wind erosion are the most visible and significant forms of degradation, but all forms are present over large areas of agricultural land (House of Representatives Enquiry into Land Degradation in Western Australia, 1988).

The fragility of Western Australia's soils has been …

Synthetic Organic Compounds: Las Vegas Wash And Lake Mead, National Water Quality Assessment Program (Nawqa): Nevada Basin And Range

Publications (WR)

The Nevada Basin and Range (NVBR) study unit of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program is investigating the status of, trends in, and factors affecting water quality in the Las Vegas area. A principal objective of the investigation is to assess the effects of urbanization on the quality of area water resources. Las Vegas Wash is the surface-water outlet for the Las Vegas area. The wash transports stormwater runoff, shallow ground-water discharge, and tertiary-treated sewage effluent from the Las Vegas area to Las Vegas Bay of Lake Mead on the Colorado River. Most of the flow—about 96 …
