Mega-fires, inquiries and politics in the eucalypt forests of Victoria, south-eastern Australia
Three mega-fires in Victoria over the period 2002–2009 burnt some 3million hectares, or 40% of the state’s public land. In the worst of these bushfires—Black Saturday, 7 February 2009–173 people lost their lives in Australia’s worst civilian tragedy. Each of these three fires was followed by intensive inquiries and investigations, the most prolonged and intensive being a Royal Commission inquiry (the most rigorous form of legal inquiry in Australia) into the Black Saturday fires.
Landscape-Scale Prioritization Process for Private Land Conservation in Alberta
There are 12 conservation land trust organizations (CLTOs) in the province of Alberta, Canada that actively steward land. Together they have protected over 1.09 million hectares of land. Using in-depth interview data with published documents on CLTOs, this paper examines how CLTOs make decisions as to which projects to pursue and the kinds of justifications they offer for the projects they have completed. We identify 13 aspects that such a decision-making process should contain. The CLTOs studied have, to some degree, incorporated 7 of them.
Summer habitat preferences of GPS-collared reindeer Rangifer tarandus tarandus
Reindeer Rangifer tarandus tarandus husbandry in Sweden commonly uses the Scandinavian mountain chain as grazing area during the snow-free season and the coniferous forests in the east during winter. Current knowledge of habitat use by reindeer is primarily based on traditional or local knowledge, or on investigations carried out on wild reindeer and caribou in other parts of the world. We identified spatial and temporal habitat use of free-ranging semi-domesticated reindeer by following 48 GPS-equipped reindeer in three summer ranges in the Swedish reindeer herding area.
Response to sewage sludge fertilisation in a Quercus rubra L. silvopastoral system: Soil, plant biodiversity and tree and pasture production
Silvopastoral systems are sustainable form of land management promoted by European Union. The productivity of the herbaceous and tree components in a silvopastoral system could be limited by soil fertility. The use of adequate doses of organic fertilisers like sewage sludge could enhance the productivity of both pasture and trees and promote biodiversity. The quantification of the best dose of sewage sludge to be applied in a silvopastoral system is important in order to enhance production and biodiversity in a silvopastoral system, while avoiding nitrate contamination of the ground water.
critical review of the science underpinning fire management in the high altitude ecosystems of south-eastern Australia
We reviewed the scope and quality of published literature relevant to management of the risk of fire and accompanying risks to ecological values, in the vegetation types (mostly forests and woodlands, but including grasslands and herbfields) of the High Country (>750m asl) of south-eastern Australia. Our analysis of quality suggests the published science has improved markedly over the past 60years. That said, there is insufficient data on any subject for a formal meta-analysis.
Water erosion-induced CO₂ emissions from tilled and no-tilled soils and sediments
The acceleration of soil erosion by water in most regions of the world in response to the anthropogenic modification of landscapes is a serious threat to natural ecosystem functionalities because of the loss of invaluable constituents such as soil particles and organic carbon (OC). While soil OC erosion is likely to be a major component of the global C cycle, water erosion-induced CO₂ emissions remain uncertain. In this study, our main objective was to compare the release of CO₂ from eroded topsoils and from the sediments exported by diffuse erosion during an entire rainy season.
Biogeographical variation in the potential effectiveness of prescribed fire in south‐eastern Australia
AIM: Prescribed fire is a common land management for reducing risks from unplanned fires. However, the universality of such effectiveness remains uncertain due to biogeographical variation in fuel types, climatic influences and fire regimes. Here, we explore biogeographical patterns in the effectiveness of prescribed fire by calculating leverage (the reduction in unplanned area burnt resulting from recent previous area burnt) across south‐eastern Australia over a 25 year period. LOCATION: The 30 bioregions of south‐eastern Australia.

Determining the effects of habitat management and climate on the population trends of a declining steppe bird
The Little Bustard Tetrax tetrax is one of the most threatened steppe bird species in Europe, due mainly to agricultural intensification. Despite the relative importance of the Iberian population (approximately 50% of the global population) little is known about its dynamics and trends, especially in core distribution areas. This study evaluates the influences of meteorological factors and land management on the oscillations and medium-term trends of two Little Bustard populations in Central Spain.
Propagation and reintroduction of two rare plant species in the South-Eastern United States of America
The habitats of Sarracenia rubra subsp. wherryi (Wherry’s pitcher plant) and Symphyotrichum georgianum (Georgia aster) have been declining as a result of human population growth, poor land management, invasive exotic species, and fire prevention. Through a partnership with the U.S. Forest Service and the Beattie Foundation measures have been taken to protect these species through a propagation and re-introduction program.
