Forestry For Wildlife Habitat Improvement. Nebraska Cooperative Extension Service Ec 81-1747, Ec 80-1747, Frank A. Hershey, Howard L. Wiegers Jan 1981

Forestry For Wildlife Habitat Improvement. Nebraska Cooperative Extension Service Ec 81-1747, Ec 80-1747, Frank A. Hershey, Howard L. Wiegers

School of Natural Resources: Faculty Publications

Wildlife cannot exist without food and protective cover. Natural and planted woodlands contribute significantly to these essentials. This circular describes habitat needs of wildlife, recommends forestry practices for habitat improvement, and gives examples of practices to improve habitat for pheasant, quail, and deer.

Variety, rather than uniformity of vegetation, benefits most wildlife species. Management which results in a diverse plant community with many stages of growth can increase the numbers and species of wildlife. Techniques which create improved conditions for woodland wildlife are fundamentally the same as those designed to grow good timber.

Report No 41 - A Survey Method For Identifying Roadside Flora Suitable For Conservation In Western Australia, John K. Scott Jan 1981

Report No 41 - A Survey Method For Identifying Roadside Flora Suitable For Conservation In Western Australia, John K. Scott

Fisheries Research Reports

A survey method for identifying flora suitable for conservation alongside roads in south-western Australia was derived from an examination of characteristics of road verges. Two roads, from Midland to Toodyay and from Armadale to Bunbury, were examined. Width of verge, weed cover, soil disturbance, vegetation structure, presence of public utilities, evidence of fire and the type of adjoining land were measured at one mile (1.6 km) intervals on both sides of the road. Also recorded were aesthetic qualities such as stands of beautiful trees and sites of special interest, e.g. the presence of rare plants.

Three variables, percentage weed cover, …


Fisheries Report No 48 - The Western Rock Lobster Fishery 1976 - 1977, G. R. Morgan, E H. Barker Jan 1981

Fisheries Report No 48 - The Western Rock Lobster Fishery 1976 - 1977, G. R. Morgan, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster Panuldinus cygnus is one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably stable …


Fisheries Report No 43 - A Pit Trap Survey Of Small Mammals, Lizards And Frogs On The Two Peoples Bay Nature Reserve, Stephen D. Hopper Jan 1981

Fisheries Report No 43 - A Pit Trap Survey Of Small Mammals, Lizards And Frogs On The Two Peoples Bay Nature Reserve, Stephen D. Hopper

Fisheries Research Reports

Ten pitlines were placed in open low woodlands near Moates Lake and in upland and coastal heathlands near Mount Gardner on Two Peoples Bay Nature Reserve during February 1980 and February 1981. The trapping program established that Common Dunnarts (Smitnthopsts murina) and Honey Possums (Tarstpes spencerae) were widespread in the reserve, and added three lizards and one frog to the list of vertebrates known to occur on the reserve.

Twenty mammals (15 native and 5 feral), four snakes, fifteen lizards, one tortoise and six frogs are now known on Iwo Peoples Bay Nature Reserve. They constitute a representative sample of …


Report No 42 - A Guide To The Gazetted Rare Flora Of Western Australia, Barbara L. Rye, Stephen D. Hopper Jan 1981

Report No 42 - A Guide To The Gazetted Rare Flora Of Western Australia, Barbara L. Rye, Stephen D. Hopper

Fisheries Research Reports

Descriptions and illustrations are provided for the first 100 taxa which have been gazetted as rare, likely to become extinct or in need of special protection under the Wildlife Conservation Act 1950-1979. Most of these rare taxa are restricted to the South-West Botanical Province and more than one-third occur in the Albany Wildlife District.

An outline is given of the means adopted to determine which taxa are gazetted as rare, the legal provisions for their protection and the biological data being sought for their management.


Fisheries Report No 46 - The Amateur Fishery For The Western Rock Lobster, Pamela N. Norton Jan 1981

Fisheries Report No 46 - The Amateur Fishery For The Western Rock Lobster, Pamela N. Norton

Fisheries Research Reports

A study of the amateur fishery for the western rock Lobster, Paulinus cygnus George, was commenced by the W.A. Marine Research Laboratories in August, 1976, and was concluded in December, 1978. The main aims of this study were to collect and analyse data to give some estimate of the distribution and magnitude of this amateur fishery.

Prior to this survey, the only catch and fishing effort data available was that obtained from the commercial fishery. Data from the amateur fishery were required in order to make a full assessment of the Level of exploitation of the stocks. In addition, 144 …


Fisheries Report No 45 - The Short Term Effects Of Brush Harvesting On The Kwongan Vegetation At Eneabba, Western Australia, E. A. Griffin, A. J. M. Hopkins Jan 1981

Fisheries Report No 45 - The Short Term Effects Of Brush Harvesting On The Kwongan Vegetation At Eneabba, Western Australia, E. A. Griffin, A. J. M. Hopkins

Fisheries Research Reports

Areas of the kwongan vegetation south of Eneabba are currently being harvested to provide brush for rehabilitation after mining. Because of the botanical importance of the Eneabba kwongan, a study of the effects of the harvesting was initiated. Three areas with different harvest histories were sampled using quadrats paired across cut/uncut boundaries. Floristic and structural differences between quadrats and between areas were assessed. The store of seed in uncut vegetation was measured.

There was a loss of species as a result of harvesting, at least in the short-term. Many species regenerated by resprouting from buds in damaged stems or in …

Vegetative Community Descriptions For The North Platte River In Wyoming And Nebraska, Lynn Fisher Nov 1980

Vegetative Community Descriptions For The North Platte River In Wyoming And Nebraska, Lynn Fisher

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

A description of the vegetative communities in an area will provide an insight to wildlife potential and use of that area. Wildlife and its corresponding habitat are recognized as important for recreation and to the overall environmental quality of an area. The Water and Power Resources Service, Lower Missouri Region, is presently engaged in a study of the Platte River Basin, including an evaluation of wildlife habitat and associated environmental needs. Quantification of wildlife habitat along the South Platte River has been completed. Vegetation communities were described and habitat maps were prepared from color infrared aerial photographs (scale – 1:24,000). …
