- Introduction and evaluation of possible indices of stand structural diversity. Staudhammer, Christina Lyn; LeMay, Valerie Marie // Canadian Journal of Forest Research;Jul2001, Vol. 31 Issue 7, p1105

- The marginal cost of structural diversity of mixed uneven-aged hard maple forests. Kant, Shashi // Canadian Journal of Forest Research;Apr2002, Vol. 32 Issue 4, p616
Focuses on the theoretical concepts pertaining to the marginal cost of structural diversity of hard maple forest in Southern Ontario. Use of matrix growth model to derive marginal cost equations of structural diversity; Elasticity of marginal cost; Trade-off between economic returns and...
- The Potential Contribution of Conifer Plantations to the UK Biodiversity Action Plan. Humphrey, J.W.; Ferris, R.; Jukes, M.R.; Peace, A.J. // Botanical Journal of Scotland;2002, Vol. 54 Issue 1, p49
Presents the results of a five-year program of research aimed at obtaining baseline information on biodiversity action plan in planted forests in Great Britain. Contribution of planted forests to the conservation of native flora and fauna; Comparison between the biodiversity of conifer...
- Overview of old-growth forests in Canada from a science perspective. Mosseler, A; Thompson, I; Pendrel, B A // Environmental Reviews;Sep2003 Supplement 1, Vol. 11, pS1
In response to a broad public concern about the rapidly diminishing area of old-growth forests and their intrinsic biological value, the Canadian Forest Service organized a national symposium in 2001 to discuss the old-growth issue from a science perspective. The objectives were: (i) to bring...
- Stability of forest biodiversity. Clark, James S.; McLachlan, Jason S. // Nature;6/5/2003, Vol. 423 Issue 6940, p635
Two hypotheses to explain potentially high forest biodiversity have different implications for the number and kinds of species that can coexist and the potential loss of biodiversity in the absence of speciation. The first hypothesis involves stabilizing mechanisms, which include tradeoffs...
- Biodiversity of floodplain forests in Europe and eastern North America: A comparative study of the Rhine and Mississippi Valleys. Annik Schnitzler; Brack W. Hale; Esther Alsum // Biodiversity & Conservation;Jan2005, Vol. 14 Issue 1, p97
Abstract In this study, we investigate the mechanisms driving biodiversity in floodplain forests with a comparison of the composition and dynamics in the warm-temperate floodplain forests of the lower Mississippi Valley and the cool-temperate floodplain forests of the lower Wisconsin and Rhine...
- Ecology: Life after logging. // Nature;8/5/2010, Vol. 466 Issue 7307, p668
The article reviews the article about the twice-logged forests by David Edwards and colleagues which appeared in the periodical "Proceedings of the Royal Society B: Biological Sciences."
- Job Done. // Horticulture Week;3/16/2012, p13
The article presents information on the Cyffin woodland Project that is run by Forestry Commission of Wales to create 100,000 hectares of new woodland in Wales, and reflects that the project will boost the wildlife and biodiversity of area.
- A strategy for identifying introduced provenances and translocations Davy, A. J.; Hewitt, G. M.; Ferris, C. // Forestry: An International Journal of Forest Research;1997, Vol. 70 Issue 3, p211
Native species of oak in Britain have been of great importance in our history for their many uses, and have thus been subject to management and planting by man for centuries. Following events such as the Enclosure Acts of the late eighteenth century and the Napoleonic wars, many oaks would have...
