This volume presents the findings of four studies of the ironwood tree found in the Sonoran Desert of Arizona and northwestern Mexico. Topics include perennial plants that depend on the shade of the ironwood for their survival, variation in the diversity and abundance of plant life under ironwood trees and elsewhere in the desert, the relationship between ironwood and a threatened species of cactu... more...

Topics include perennial plants that depend on the shade of the ironwood for their survival, variation in the diversity and abundance of plant life under ironwood trees and elsewhere in the desert, the relationship between ironwood and a threatened species of cactus, and the harm done to ironwood trees by logging, the tourist trade, and misguided conservation eff   less...

In 2006, conservationists everywhere celebrated the 100th anniversary of professional forestry in Maryland, the Old Line State. Under the leadership of Fred Wilson Besley, Maryland's first and the nation's third state forester, scientific forest management and the larger conservation impulse became firmly ensconced.

In 2006, conservationists everywhere celebrated the 100th anniversary of professional forestry in Maryland, the Old Line State. Under the leadership of Fred Wilson Besley, Maryland's first and the nation's third state forester, scientific forest management and the larger conservation impulse became firmly ensconced. A protégé of America's most famous forester, Gifford Pinchot, Besley moved aggressively to   less...

This work, published in two volumes, contains descriptions of the wood and bark anatomies of 3000 dicotyledonous plants of 120 families, highlighting the anatomical and phylogenetic diversity of dicotyledonous plants of the Northern Hemisphere. The first volume principally treats families of the Early Angiosperms, Eudicots, Core Eudicots and Rosids, while the second concentrates on the Asterids. P... more...

This title contains the proceedings of a seminar held on 22 and 23 February 1994. Ireland has less forest than any other country in the European Union. The 1994 seminar of the Irish National Committee for Biology set out to put this fact in its historical context and then to examine current forest policy in the island, north and south. The final session of the seminar examined new uses of woody pl... more...

The 1994 seminar of the Irish National Committee for Biology set out to put this fact in its historical context and then to examine current forest policy in the island, north and south. The final session of the seminar examined new uses of woody plants and the contribution of biotechnology to the production of elite trees for future forestry.   less...
