The Prey Of Common Barn Owls (Tyto Alba) In Dry Limestone Scrub Forest Of Southern Jamaica, Donald A. Mcfarlane, Kimball L. Garrett
The Prey Of Common Barn Owls (Tyto Alba) In Dry Limestone Scrub Forest Of Southern Jamaica, Donald A. Mcfarlane, Kimball L. Garrett
WM Keck Science Faculty Papers
A collection of common barn-owl (Tyto alba Scopoli) pellets from caves on the Portland Ridge of Jamaica reveals that whereas introduced rodents constitute approximately 90% of the total prey, bats and birds are also frequent prey items. Of the bats, frugivorous species predominate with Ariteus flavescens Gray and Artibeus jamaicensis Leach accounting for the largest portion of the bat prey. Insectivorous bats are markedly under-represented with respect to the known diversity of insectivorous species in the habitat.

Water Erosion On Vegetable Growing Land In South Western Australia, D J. Mcfarlane, N D. Delroy, H V. Gratte, J P. Middlemas, A M E Van Vreeswyk, I Mckissock
Water Erosion On Vegetable Growing Land In South Western Australia, D J. Mcfarlane, N D. Delroy, H V. Gratte, J P. Middlemas, A M E Van Vreeswyk, I Mckissock
Resource management technical reports
The most serious erosion was found to be occurring in the Donnybrook area due to a combination of erosive winter rainfall, steep slopes and erodible soils. The most serious erosion was found to occur when storm runoff entered the vegetable plots from above, providing a transporting medium for the cultivated soil. A predictive model of erosion showed that soil texture, furrow slope, plot length, rainfall erosivity and canopy cover were significant factors affecting soil loss.
The Effect On Farm Profit Of Conserving Stubble To Prevent Wind Erosion, A D. Bathgate
The Effect On Farm Profit Of Conserving Stubble To Prevent Wind Erosion, A D. Bathgate
Journal of the Department of Agriculture, Western Australia, Series 4
Over-grazing of stubbles is a major cause of winf erosion on WesternAustralian farms. Stubble contributes to the 'roughness' of the paddock; as the roughness is reduced, the risk of winf erosion is increased.
The risk of lupinosis in sheep has previously reduced the likelihood of lupin stubble being over grazed, but the development of Gungurru, a phomopsis-resistent variety of lupin, has increased the potential for over-grazing and hence the probability of wind erosion.
This article describes the economic benefit (or cost) of conserving stubble at the conservation standards.

Planning For Horticultural Expansion On The Swan Coastal Plain, P Coghlan, Geoff Moore, Jim Dixon
Journal of the Department of Agriculture, Western Australia, Series 4
Horticulture is an intensive, high value form of agriculture highly dependant on the availability of good water supplies for the year-round production of fresh produce. Production increase in Western Australia and the encouragement and development of export markets has caused rapid expansion if the industry in recent years.
Expansion is expected to continue, placing severe pressure on available water supplies and suitable land close to markets. At present' 90 per cent of the Stase's horticultural land is on the Swan Coastal Plain and minor selected hills areas around Perth.

Pasture Species Evaluation On Acid Wodjil Soil - Machine Sown Plots., Bradley Nutt
Experimental Summaries - Plant Research
Trial 89TS38
Location: East Latham
The very low seed yields are a reflection of the dry winter conditions experienced in 1989. The Rose (T. hirtum) and Cupped (T. cherli) clovers appear to be a more promising option for this difficult soil type compared to other species. Paros yellow serradella performed well considering the trial site is located in a very dry area. The burr medics would not be an option on these acidic soil types because of nodulation failure; which should become evident in the regenerating swards.
