The AA. divide the 388 species of endangered plants recorded in the first volume of China Plant Red Data Book into 7 types : living fossils| ancient relics| species of only a small range| monospecific genus| the important element of the flora
This paper considers key issues in plant invasion ecology where findings published since 1990 have significantly improved the understanding of many aspects of invasions. The review focuses on vascular plants invading natural and semi-natural
The distribution in space and the propensity to be associated with other plants species, can well be considered as important dimensions of the ecological niche of a plant. This is demonstrated by the results obtained during a vegetation survey

The main focus of this study was to detect adaptations of plants to the extremly arid environments and to calculate the water use of relevant wild and agricultural plant stands. In addition this investigation was supposed to give hints
This article addresses the trends, problems and opportunities attending the cultivation and marketing of medicinal and spice plants in Germany. The years since 1993 have seen an expansion in their cultivation to a current area of some 10,000
Plant functional types : an alternative to taxonomic plant community description in biogeography ?
Cet article constitue une revue critique du concept des types fonctionnels des plantes comme alternative à l'approche traditionnelle taxonomique. Celle-ci est basée sur les espèces pour la description des communautés de plantes en biogéographie et

This paper identifies the historical precedents and recent advances in descriptive and analytical aspects of invasive plant ecology. It focuses primarily on natural and semi-natural systems. The dynamics of plant invasions depend on the unique
combination of species and recipient environments in light of short-lived, but highly influential stochastic events. Plant invasions occur across all habitat types and have spawned complementary theories, which are briefly presented within particular contexts.

Tree planting by tenants in County Down during the eighteenth and nineteenth centuries
Registers of tenant tree planting between 1769 and 1909 are examined. 5.13 million trees were planted. Registrations were highest in the decade 1810-29, declining sharply in the mid-1830s. Numbers of trees planted peaked in the 1820-29 and 1830-39
decades as plantations became prominent. Three quarters of trees planted were conifers and larch accounted for 51% of all trees planted. Landscape impacts of planting are discussed in comparison with present woodlands and trees.
The A. investigates about the macro-economic forces and corporate strategies underlying closure. Branch plant closures are considered within a framework which emphasises these wider issues and distinguishes between motivation and selection
, cessation and selective closures, and plant and area characteristics. Changes in the market and lack of competitiveness are the most common motives for closure.
