Microbiology may be described as one of the younger sciences with its history, as a precise subject, only dating as far back as Pasteur in the mid 1800s and his revelation both of the role of microorganisms in nature and their importance to human welfare.
When I received an invitation to attend the International Symposium on Lethal Yellowing being organised by the Centro de Investigacion Cientifica de Yucatan (CICy), I was excited and a little nostalgic.
This volume characterizes the current state of natural science and socioeconomic modeling of the impacts of climate change and current climate variability on forests, grasslands, and water.
During its 200-year history the concept of sustainable forest ecosystem management has been the object of scientific and political discussion, with varying degrees of intensity - promoted with vehement fervour during periods of social or economic crisis, and less intensely during periods of stability.
As an introduction to the present book I would like to explain how it was, that I, a commercial nurseryman, became so keenly interested in Conifers and their nomen- clature.

The "e;International Symposium on Scleroderris Canker of Conifers"e; held June 21-24, 1983 in Syracuse, New York was the result of mutual interest expressed by the USDA Forest Service, the Canadian Forestry Service, and the State Uni- versity of New York College of Environmental Science and Forestry (SUNY ESF).
As J understand it, a book Preface is where the author explains to the reader how the book in hand came about, something of the personal reasons for having inflicted such extended duress on one's self to complete the manllscript.
Plantations of a wide range of tree species have assumed an important place in our world, providing wood for industry, fuelwood and animal fodder, protection from adverse environments and for the soil, as well as amenity and aesthetically pleasing landscapes.
In analysing the development and achievements of Polish forestry and forest industries over the last four decades, it is necessary to take into consideration the situation prevailing after the end of the Second World War, when these sectors of the national economy were starting their activities.
The Western Australian jarrah forest is unique, contammg some of the most beautiful flora in the world, more than 100 species of birds and some 50 mammals indigenous to this State.
