From the text...'The benefits of prescribed fire are many, but prescribed fire is a complex tool and should be used only by those trained in its use. Proper diagnosis and detailed planning are needed for every area where burning is contemplated. The incomplete assessment of any…

Slow combustion or burning of dry or green plant material from many sources produces volatile compounds that are water soluble and that stimulate the germination of many seeds with different dormancy strategies. The active prinicipals are apparently produced around 160-200ºC and…

Epacris stuartii (Epacridaceae) is an endangered heathland shrub in which seedling recruitment occurs almost exclusively after fire. Seed viability and multiple seed dormancy mechanisms were examined to explore why levels of seedling recruitment were low after some fires,…

Prescribed fire as a social issue becomes automatically an ecological, political, and economic issue. Any issue that affects us socially we take to the political arena, and its final resolution will involve the costs of different avenues to resolving the issue. Unfortunately,…

Wildland fires are an integral part of many ecosystems across North America; and these ecosystems often exhibit adaptations to periodic fire. These fire-adapted ecosystems are often termed fire-dependent, if recurring disturbances by fire are essential to the functioning of the…

Anthropogenic activities of the past century have caused a dramatic increase in global air pollution. This process has accelerated in the past few decades, and emissions of carbon dioxide, nitrogen oxides, or chlorofluorocarbons caused serious changes in the earth's climate, e.g…

Most of the research about the effects of the release of carbon and other chemicals to the atmosphere during forest fires focuses on emissions from crown fires or slash fires in which a high percentage of the fine fuels are burned. However, in many temperate and boreal conifer…

Global annual NO emissions from soil are of the order of 10 Tg NO-N. This is about half the amount fossil fuel combustion processes contribute to the annual global NOx budget. Reducing the emissions of soil derived NOx requires an understanding of the source of the flux and the…
