In many cities worldwide, urbanization is leading to the rapid and extensive fragmentation of native vegetation into small and scattered urban remnants. We investigated the effects of fragmentation on plant species richness and abundance in 30 remnant Banksia woodlands in the rapidly expanding city of Perth, located in the southwestern Australian global biodiversity hotspot.

There is an urgent and immediate need to address the excessive cost of large fires. Here, we studied large wildland fire suppression expenditures by the US Department of Agriculture Forest Service. Among 16 potential non-managerial factors, which represented fire size and shape, private properties, public land attributes, forest and fuel conditions, and geographic settings, we found only fire size and private land had a strong effect on suppression expenditures. When both were accounted for, all the other variables had no significant effect.

Among the Dayak people in East Kalimantan, simpukng (“forest gardens”) are an important component of their traditional farming systems. Simpukng is managed secondary forests in which selected species of fruits, rattan, bamboo, timber and other plants are planted. While most are owned by families and passed down from one generation to the next, some are managed on a communal basis. Complex customary Dayak rules exist that control the use and inheritance of these forests that help to avoid over-exploitation of resources.

Livestock that is extensively managed can have higher diversity and abundance of insects in comparison to intensively managed livestock, although data are more equivocal within a gradient of extensively managed pastures. Additionally, biodiversity on farms is vulnerable to degradation of the surrounding landscape and changing patterns of land use. We monitored Coleoptera and Hemiptera on grass-fed cattle farms in North Carolina to determine effects of cattle and land use patterns on biodiversity.

Along the path of water flowing in a river basin are many water-related human interventions that modify the natural systems. Rainwater harvesting is one such intervention that involves collecting and use of surface runoff for different purpose in the upstream catchment. Increased water consumption at upstream level is an issue of concern for downstream water availability to sustain ecosystem services.

The Promotional Paper Forest Land Transformation in Latvia by Gunta Bāra has been developed at the Forest Faculty of the Latvian University of Agriculture between 2001 and 2007. Goal of the Promotional Paper: to identify the main problems in transformation of forest land in the Republic of Latvia and gaps in legislative instruments regulating the process of change of land use type, to prepare recommendations for their elimination, to develop a methodology for calculation of compensation for the losses caused to the state as a result of destruction of natural forest environment.

Using an analysis of aerial photographs from 1942, 1985 and 2004 we assessed the impact of changing land tenure and land-use regimes on the cover of thicket vegetation on the Grahamstown commonage. Land-use impacts were examined by comparing plant species composition within three vegetation types between sites incorporated into commonage for different lengths of time and sites outside the commonage. Results showed that thicket cover increased by 87% between 1942 and 1985 but declined by 11% between 1985 and 2004.

In the vicinity of a city, farmers are confronted with increasing agricultural land prices and rents along the rural-urban gradient, but they concurrently enjoy the advantages associated with proximityto a larger and wealthier consumer base. We hypothesize that farmers transition fromlow-value, land-intensive \traditional" crops to high-value, labor-intensive \specialized" crops on parcels located closer to urban centers. Once returns to development of a parcel exceed theprofits associated with farming, exurban farmers may sell their land for conversion to urban use.

Groundwater exploration in the Western Doon valley has been carried out to delineate the groundwater potential and groundwater quality zones suitable for domestic purposes based on the integrated use of Remote Sensing and Geographical Information Systems (GIS). The Western Doon Valley, occupying broad synclinal troughs in the evolving fold-thrust system of sub-Himalaya, which is filled by post-Siwalik fluvial and debris flow deposits in the late Quaternary-Holocene.

This work describes the methodological approach used for mapping the potential infiltration areas of the Guaratinguetá watershed (160 km2), situated in Southeastern Brazil. The method is considered a qualitative approach, which takes into account thematic maps (geology, pedology, geomorphology, and land use/land cover) and the precipitation spatial distribution. A group of experts in Earth Sciences and Geotechnical Engineering has applied an infiltration potential scale factor that ranges from 5 (highest influence) to 1 (lowest influence).

Landscapes in urban areas especially in developing countries are under pressure due to increasing population of urban dwellers and un-directed spread of city boundaries. Sound urban environment plays important aesthetic, ecological, cultural, social and engineering roles beneficial to the people. To support better management of vegetated sites, it is necessary to understand the spatial configuration at the landscape scale and changes that have occurred.

A new methodological framework for plant diversity assessment at the landscape scale is presented that exhibits the following strengths: (1) potential for easily standardizable sampling procedure; (2) characterization of disturbance regime; (3) use of selected disturbance descriptors as explanatory variables which probably allow for better transferability than site specific land use types--for example, to evaluate the emerging use of energy plants that pose novel management challenges without historic precedence to many landscapes; (4) analysis of quantitative and qualitative aspects of pla
