AB: Brief accounts are given of the legal and administrative framework for wetland regulation in the USA, the nature of cumulative effects of human activities on the environment and the use of ecological principles (specifically those of landscape ecology) in environmental planning. The cumulative effect of human activities on forested wetlands was assessed in the Tensas River basin, Louisiana; the use of the assessment for planning purposes is demonstrated. The generality of the approach and its applicability in other contexts are discussed.

AB: The government of Fairfax County, Virginia, has developed an ecological-resources inventory/information system for practical use by local decision-makers. Forested-wetland communities are among the habitat types found in FairfaxCounty. This inventory and information system has been a process of separate but related tasks, including the formation of a technical steering committee, definition and description of habitat types found in FairfaxCounty, development of a baseline field-survey method, development of an automated database system, and use of a change-detection method for system updating and maintenance. This information system will provide a workable 'picture' of natural communities in FairfaxCounty, and will benefit various needs of County and regional resource-management agencies. By obtaining and managing specific resource information, this process will provide the foundation necessary for Fairfax's legislators to reach informed decisions for land-use planning and resource management.

AB: The aim of this paper is to discuss the potential for sustainable management of natural ecosystems of farms in New Zealand focusing on three issues. Firstly, the New Zealand vegetation is described, and some of the difficulties for achieving sustainable management discussed. Secondly, a case study is presented in order to highlight constraints and opportunities at a local scale, and also to show how an understanding of landholder attitudes might help to improve existing conservation policies. Finally, the possible management implications of the new Resource Management Act 1991 and Forest Amendment Act 1993 are discussed. It is argued that these Acts may bring to an end the years of destruction of New Zealand's natural environment.

AB: To assess the power of point data (collected systematically at each metre along a permanently situated, 100-m line transect) to detect actual changes in plant basal cover, a computational approach whereby a simplified shortgrass steppe community was spatially simulated on a computer screen was developed. Cover was then reduced using a random disturbance pattern. One transect could detect an actual decrease in cover from 12% to 8% with <20% probability, while 5 transects increased this power to about 80%. A reduction in cover from 12% to 6% could be detected with 80% probability with only 2 transects, while a cover reduction to 10% could only be detected with 40% probability using 10 transects. It was considered that artificial populations provide a valuable mechanism for quantitatively evaluating field sampling designs.

AB: The effects of the introduction of Environmentally Sensitive Area grassland management prescriptions on the economics and plant ecology of a farm in the Pennine Dales, UK, were assessed within a decision support modelling system. Sheep stocking rates were predicted to fall from an overall rate on the farm of 3.1 ewes per ha to 1.7 ewes per ha, and the suckler cow enterprise was expected to be discontinued when the ESA management agreement was initiated. Whilst hay-making activity was predicted on the inbye land under ESA management, the results of the farm level economics model also suggested that the amount of supplementary feed per ewe and other relative input levels would increase. Overall, farm management and investment income rose with the introduction of ESA management although this was only relative to the financial performance of the previous year, which was observed as being somewhat below average. The predicted changes in management were used as inputs to the NELUP vegetation-environment-management model to determine probable changes in vegetation on the farm following ESA management. The amount of heather on the rough pasture was expected to increase, whilst on the inbye land, the species composition of the vegetation was predicted to be that of a hay meadow community.

AB: Annual production and redistribution of leaf litter were compared among three distinct understorey patches in a temperate hardwood forest dominated by Quercus mongolica, Kalopanax pictus [K. septemlobus], Acer pseudosieboldianum, and Carpinus cordata. The study area is on Mt.Jumbong, Kangwon Province, Korea. Two patches were located on a southwest-facing slope: one with an understorey dominated by herbaceous plants (Patch S), and the other covered with evergreen dwarf bamboo, Sasa borealis (Patch SS). The third patch was on the opposite slope with an understorey dominated by herbaceous plants (Patch N). Annual leaf litterfall averaged 330 g/msuperscript 2 in the three patches from 1994 to 1998. From mid-September 1996 to mid-September 1997, net transport of leaf litter over patch boundaries was 1824 g/m from Patch S to SS, 1465 g/m from Patch S to N, and 886 g/m from Patch SS to N. The amounts moving downslope out of Patch S, SS, and N were 2548, 471, and 588 g/m, respectively. When a mass balance approach was employed for the data on leaf litter transport, the results were relatively consistent with 216, 631, and 724 g/msuperscript 2 of leaf litter stores in Patch S, SS, and N, respectively, in April 1997. This study suggests that leaf litter redistribution is largely regulated by aspect and understorey type and exerts a significant effect on carbon processes in the forest ecosystem.

AB: Satellite remote sensing techniques were used to map the distribution and extent of native vegetation clearance in a 70x90 km area of the Nyngan region in New South Wales, Australia. The predominant vegetation communities in the study area were: (1) red box (Eucalyptus intertexta), poplar box (E. populnea) and pine woodlands (Callistris glaucophylla); and (2) western poplar box woodlands. The study also determined whether the introduction of legislation has led to a reactionary response in the Nyngan region. Landsat Thematic Mapper imagery was acquired for the years 1994 to 2002, which allowed for an adequate temporal scale by which legislative impacts could be discerned. Clearing continued in the Nyngan region throughout the study period. The total area of clearing was 21 146 ha. The largest rate of change in clearing occurred during 1995-96, from 1250 to 4087 ha. This period of increased clearing was also the period during which the State Environmental Planning Policy 46 was introduced. In the subsequent periods, clearing progressively increased, reaching 1529 ha between 1997 and 1998, and 2219 ha between 1998 and 1999, despite the implementation of the Native Vegetation Conservation Act 1997 (NVCA) in early 1998. Results indicate that the implementation of the NVCA has not significantly reduced the amount of clearing occurring in the Nyngan region.

AB: During land transformation process in the human history, naturalized plants were introduced to several land use patterns by the different ways of plant itself. Including some naturalized plants that had contributed to land restoration, many naturalized plants have invaded the original habitat or landscape of native plants. Once the plants were colonized, they extend their area and population size. Urban developed areas often give an important role of source habitat for naturalized plants and expand their population size. Recently, this situation appears as one of the environmental problems on the urban landscape management controlling the naturalized plants that invaded the developed area and conserving the native vegetation. This paper focuses on the relationships between distribution of habitat of naturalized plants and landscape patch in urban area in Seoul, Korea Republic. Gangdong-Gu, one of the administrative areas in Seoul was selected for this study. We examined the recent land use change using LANDSAT TM data and spread the representative naturalized plants (Robinia pseudoacacia and Eupatorium rugosum) by Seoul Biotope Mapping Project and field survey in 1999. As a result, these two species often occurred in the same habitat and distributed in forest edge disturbed by man. Their distribution patterns were related to landscape indices (patch size and shape) in the forest edge.

AB: There is a great demand for quantitative predictions of the effect of land use changes on water and nitrogen dynamics in environmental planning. The interactions between human activities, vegetation, soil processes and hydrology are quantified with the DILAMO approach in a 32-km2 sub-basin in northern Germany and analysed at various spatiotemporal scales. The linkage of a process-oriented model with GIS identified spatially explicit sandy areas covered with crops as quantitatively the most important input sources for nitrogen. Nitrogen loads from the sub-basin to surface water bodies were 40% less than the conditions in a scenario where the groundwater level was raised by only 30 cm. Nitrogen retention particularly increased in newly established surface flow wetlands.

AB: An ecotope (spatial eco-space) map that considers topography and bio-organism-relevant variables emerges as an important basic framework when landscape-scale characteristics for ecosystem management and wildlife conservation are needed. A spatio-geoecological framework based on geographic information systems (GIS) and a vegetation survey were developed for wildlife habitat evaluation of national parks and applied to a representative rugged valley area of Mt.SorakNational Park in Korea. An ecotope map was classified into hundreds of types and dozens of groups by combining biological and geophysical variables. Variables included: forest vegetation type, topographic solar radiation, normalized difference vegetation index (NDVI), elevation, and anthropogenic factors, such as, streams and roads. Layers of GIS variables were produced by field surveys, modelling, satellite images, or digitalization. Vegetation surveys were carried out to identify finer-scale distribution of vegetation types in the rugged valley area. Digital forest vegetation maps from the Forestry Administrator were then modified using the field-surveyed vegetation maps. Topographic solar radiation was predicted with a daily topographic radiation model. The NDVI was calculated from the satellite imagery of a Landsat Thematic Mapper. A digital elevation model was used and the other layers were digitized using topographical maps with a scale of 1:25 000. The aim of this study is to determine the geoecological factors relating to the spatial pattern of plant community. It was cleared by the spatial pattern of environmental variables and vegetation characteristics by detrended correspondence analysis using plant species and the environmental variables of each plot. The ordination component value of the first axis shows significant regression to some environmental variables. A case study of habitat evaluation was carried out using the resultant ecotope map. The spatial distribution of potential goral habitat and vegetation characteristics were predicted and the impact of human trails on the neighbouring vegetation was also examined for restoration planning. The GIS-based framework developed for wildlife habitat evaluation is useful for natural resource management and human activity control in national parks in Korea.
