“…Although the ease of access to photography for documentary purposes has clearly contributed to the decrease in collecting from the 1980's onward, the interval between the "Heroic Era" and the botanists of the 1990's was probably so long that many young botanists have come to underrate the value of collecting. Possibly, this is mirrored in the figures for the latest years: the number of collected specimens has increased in the last decade, but the number of collectors has decreased gradually since the 1980's, although this seems to be a more general phenomenon that extends far beyond Hungary (Prather et al 2004). …”

The paper introduces the Herbarium Database of Hungarian Orchids which contains all records of orchid (Orchidaceae) specimens stored in the Hungarian herbaria. All data from the herbarium sheets were entered into the database, and secondary data were also added it; including a taxonomic revision in line with current theory. Only unique data was considered, yielding 7,658 records of 55 species from 452 collectors. It covers the whole territory of Hungary, and spans two centuries ranging from 1804 to the present. The temporal frequency of collections shows a peak in the middle of the 20 th century. The most effective collectors came from this era, and the name of Rezső Soó and his followers can be mentioned as most prominent. As in other countries, a decline in collection is seen in the last decades of the 20 th century. A geographically uneven coverage of collections was observed, and the such heavily underrepresented regions could be identified with the help of the database. However, the value of collection for scientific purposes is emphasised, as can be readily seen in this database. Taxonomically, seven recently described species could be identified, which were collected before their description under other names more than one century ago. On the other hand, the earlier presence of species now considered to be extinct could be unequivocally proven, as in the case of Malaxis monophyllos. The multiple application of herbaria is illustrated by some examples, reinforcing unambiguously the usefulness of collecting for scientific purposes. Furthermore, new, as yet unforeseen, application of herbarium collections can be expected.

“…According to Prather et al (2004), herbarium samples are the basis for floristic inventories. These, in turn, describe the richness of a region in several qualitative ways, such as the number of vascular plant species and families, proportion of the total species associated with each life habit, dispersal and pollination syndrome, and also investigate occurrences of threatened species.…”

The Mata dos Godoy State Park (MGSP) is a remnant of the Seasonal Semideciduous Forest in northern Paraná, with an area of 690 hectares. The MGSP flora inventory was produced from a survey of herbarium specimens deposited in the FUEL Herbarium. The result was the catalogue of 508 species, among which we screened 40 specimens of ferns and lycophytes, and the remainder was classified as angiosperms. The two richest families among the ferns were Polypodiaceae and Pteridaceae, whereas among the arboreal angiosperms, Leguminosae and Myrtaceae stood out, confirming the floristic profile of the lower Tibagi River basin. Among the species, 12 can be classified as naturalized and 21 are among the threatened species in the state of Paraná, besides the inclusion of species whose collections were reduced in Brazil. These results indicate the MGSP as an important area for the representation of the Seasonal Semideciduous Forest in northern Paraná.

“…Baker-Snoqualmie National Forest, and a species known to be invasive in Oregon and California (Geranium lucidum L.). Contrary to the situation at WTU, there is an overall decline in the growth of herbaria collections throughout the U.S. (Prather et al 2004a). This decline is compromising efforts to detect when potentially invasive species become established in the wild and the ability to assess how quickly such species may spread (Prather et al 2004b).…”

This proceedings includes twenty-seven papers based on oral presentations at the conference plus a synthesis paper that summarizes workshop themes, discussions, and related information. Topics include early detection and rapid response; control techniques, biology, and impacts; management approaches; distribution and mapping of invasive plants; and partnerships, education, and outreach.
