LANDFIRE is a large interagency project that supports national fire management and fuels treatment activities. A primary data product of LANDFIRE is a detailed vegetation type classification. This study describes how independent data from Landsat imagery, topographic data, biophysical data layers, and dependent field-collected data can be used in a hierarchical mapping approach to improve veget...

The objective of our work was to verify the value of the vegetation corridor in the conservation of small mammals in fragmented tropical landscapes, using a model system in the southeastern Minas Gerais. We evaluated and compared the composition and structure of small mammals in a vegetation corridor, forest fragments and a coffee matrix. A total of 15 species were recorded, and the highest spe...

Forests are usually assessed as a discrete land cover type. However, we hypothesise that the resources associated with forests show diverse spatial patterns, only partially matching current forest boundaries. Therefore tree vegetation parameters related to relevant forest resources at the landscape level were assessed for the Canton of Geneva in western Switzerland. LIDAR based digital terrain ...

Climate, vegetation and humans act on biomass burning at different spatial and temporal scales. In this study, we used a dense network of sedimentary charcoal records from eastern Canada to reconstruct regional biomass burning history over the last 7000 years at the scale of four potential vegetation types: open coniferous forest/tundra, boreal coniferous forest, boreal mixedwood forest and tem...

The boreal forest is one of the largest terrestrial biomes and plays a key role for the global carbon balance and climate. The forest floor vegetation has a strong influence on the carbon and nitrogen cycles of the forests and is sensitive to changes in temperature conditions and nutrient availability. Additionally, the effects of climate warming on forest floor vegetation have been suggested t...

Article history: Received 31 December 2006 Accepted 2 January 2007 The goal of this study was to evaluate the contributions of forest and landscape structure derived from remote sensing instruments to habitatmapping. Our empirical data focused at the landscape scale on a test site in northern Michigan, using radar and Landsat imagery and bird-presence data by species. We tested the contribution...

The Upper Guinea Forest (UGF) region of West Africa is one of the most climatically marginal and human-impacted tropical forest regions in the world. Research on the patterns and drivers of vegetation change is critical for developing strategies to sustain ecosystem services in the region and to understand how climate and land use change will affect other tropical forests around the globe. We c...

In recent years, forest fires frequency and intensity has increased, causing a new awareness about their impact not only on vegetation, but also on hydrological regime. Changes in vegetation influence the processes of interception and evapotranspiration, seriously affecting the hydrological cycle. Forest fires can also affect hydrological processes indirectly, altering the hydraulic properties ...
