Do Different Relevance Attributes Indicate The Same Conservation Priorities? A Case Study In Caves Of Southeastern Brazil, Maysa F.V.R. Souza, Denizar A. Alvarenga, Marconi Souza-Silva, Rodrigo L. Ferreira
Do Different Relevance Attributes Indicate The Same Conservation Priorities? A Case Study In Caves Of Southeastern Brazil, Maysa F.V.R. Souza, Denizar A. Alvarenga, Marconi Souza-Silva, Rodrigo L. Ferreira
International Journal of Speleology
In the last decade, the scientific community brought to the debate gaps that slow down the advance of knowledge regarding global biodiversity. More recently, this discussion has reached subterranean environments, where these gaps are even more dramatic due to the relict and vulnerable nature of their species. In this context, we tested ecological metrics related to some of these gaps, checking if the biological relevance of the caves would change depending on ecological attributes related to each metric. The study was carried out in caves from southeastern Brazil, located in a region presenting a high richness of troglobitic species restricted …

Agriculture And Nature Conservation In The Moravian Karst (Czech Republic), Ivan Balák, Jozef Janèo, Leos Stefka, Pavel Bosák
International Journal of Speleology
Moravian karst is a narrow strip of limestone with long history of settlement, agricultural use and man impact to karst. It is naturally divided into smaller units - karst plateaus - separated by deep valleys (glens). Each plateau has different proportion of land use, i.e. the percentage of agricultural land, forests, etc. The agricultural land constitutes now up to 70% in the north and max. 30% in the centre and south of the total area of plateaus. Intensive agricultural use of the arable land since 60ties of this Century caused great impact to quality of soils and groundwater by overdoses …
Impact Of Agricultural Land Use On Some Hungarian Karst Regions, Ilona Bárány-Kevei
Impact Of Agricultural Land Use On Some Hungarian Karst Regions, Ilona Bárány-Kevei
International Journal of Speleology
The karst regions are found in the medium altitude mountains of Hungary. Their land use types are natural and sustainable forestry, grazing and vineyards. In international comparison, Hungary belongs to those countries of Europe where arable land is abundant, therefore, in the future its extension has to be reduced. That means agricultural activity has to be restricted on the sensitive karst surfaces. This paper presents ways of sustainable forestry and other land use types for three karst regions of Hungary.
Nature Conservation In The Western Australian Wheatbelt, Max Abensperg-Traun
Nature Conservation In The Western Australian Wheatbelt, Max Abensperg-Traun
Journal of the Department of Agriculture, Western Australia, Series 4
Growing concern about the survival of flora and fauna in the Western Australian wheatbelt prompted CSIRO scientists to start a long-term study to moniter trends in populations. Max Abensperg-Traun and his colleagues reportt on their findings so far.
Wildlife Corridors In The Wheatbelt, Richard Hobbs, Denis Saunders
Wildlife Corridors In The Wheatbelt, Richard Hobbs, Denis Saunders
Journal of the Department of Agriculture, Western Australia, Series 4
Native vegetation in the Western Australian wheatbelt now persists mostly in small areas that remained uncleared for various reasons. (See 'Remnant vegetation on farms is a valuable resource' on page 43.) On their own, most of these remnant areas are difficult to manage, and too small to retain viable populations of many of the birds and other animals found in the wheatbelt. These patches of vegetation can be linked by wildlife corridors, which may increase the ability of the wildlife to move about and persist in the area
The Greening Of Australia, Martine Scheltema
The Greening Of Australia, Martine Scheltema
Journal of the Department of Agriculture, Western Australia, Series 4
Many urban Australians have little understanding of the problems of land degradation because it's an extremely slow process that doesn 't directly influence their day-to-day lives. Understandably, they would have trouble relating to sub-soil compaction, waterlogging, increased soil acidity and salinity. They also have trouble comprehending why fencing according to soil type is an important management tool for farmers, or what role contour banks, drainage systems, the addition of gypsum and planting trees have in reversing land degradation. But given that tree loss "has been at the core of almost every aspect of land degradation in Australia ", and that …
Remnant Vegetation On Farms Is A Valuable Resource, Richard Hobbs, Ken Wallace
Remnant Vegetation On Farms Is A Valuable Resource, Richard Hobbs, Ken Wallace
Journal of the Department of Agriculture, Western Australia, Series 4
Retention of native vegetation on farms is important both from an ecological and an economic point of view. Productivity in the paddocks ultimately will depend on the retention and replacement of trees and shrubs in the landscape. Remnants of native vegetation can play their part by helping to ensure the long-term viability of the agricultural system, as well as greatly enhancing the quality of life for those living on the land.
Can Kangaroos Survive In The Wheatbelt?, Graham Arnold
Can Kangaroos Survive In The Wheatbelt?, Graham Arnold
Journal of the Department of Agriculture, Western Australia, Series 4
One of the costs of agricultural development in Western Australia over the past 100 years has been the loss of most of the native vegetation and, consequently, massive reductions in the numbers of most of our native fauna. Thirteen mammal species are extinct and many bird and mammal species are extinct in some areas. These losses will increase as remnant native vegetation degrades under the impact of nutrients washed and blown from farmland, from the invasion by weeds and from grazing sheep.
Even kangaroos are affected. Unless the community manages remnant vegetation to minimise degradation and enhance the regeneration of …
Conservation Of The National Estate, Department Of Agriculture, Western Australia
Conservation Of The National Estate, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
In 1973 the Australian Government established a Committee of Inquiry under Mr. Justice R. M. Hope to inquire into the National Estate. Under its terms of reference the Committee was to assess the nature and condition of the National Estate and the measures which were being and should be taken for its preservation and enhancement.
Officers of the Department of Agriculture recognise that there are basic natural resources such as land, water, gene material and ecosystems which are essential elements of the National Estate held in trust by successive generations.
In a submission to the Inquiry, matters of particular concern …
Flora And Fauna Conservation : A Plea To Landholders, Clee Francis Howard Jenkins
Flora And Fauna Conservation : A Plea To Landholders, Clee Francis Howard Jenkins
Journal of the Department of Agriculture, Western Australia, Series 4
MUCH of the recent discussion on conservation has centred around the importance of wild flower reserves and the necessity for protecting one of the State's most important tourist attractions.
Although less important to visitors than the flowers, many of our wild animals hold equal interest for nature lovers and scientists, and they also need protection.

NOW that several species of native plants have become totally extinct and many more are becoming rare almost to the point of extinction, interest in the scientific and aesthetic potential of the West Australian flora is awakening.
