This paper builds on previous work by our research group which demonstrated the applicability of a parametric model, Modified C-Fix, for the monitoring of Mediterranean forests. Specifically, the model is capable of combining ground and remote sensing data to estimate forest gross primary production (GPP) on various spatial and temporal scales. Modified C-Fix is currently applied to all Italian...

BACKGROUND Sustainable forest management (SFM), which has been recently introduced to tropical natural production forests, is beneficial in maintaining timber resources, but information about the co-benefits for biodiversity conservation and carbon sequestration is currently lacking. METHODOLOGY/PRINCIPAL FINDINGS We estimated the diversity of medium to large-bodied forest-dwelling vertebrate...

As part of the intensive field campaign (IFC) for the Boreal forest ecosystematmosphere research (B OREAS) project in August 1993, the NASA/JPL AIRSAR covered an area of about 100 km x 100 km near the Prince Albert National Park in Saskatchewan, Canada. At the same time, ground-truth measurements were made in several stands which have been selected as the primary study sites. This paper focuses...

Recent rising public concerns about climate change and increasing energy costs have led to the need to re-evaluate forest biomass as an alternative energy feedstock. Biomass harvesting could potentially impact ecosystems in various ways, including site productivity and forest stand dynamics. Since these issues influence decision-making, the effects of biomass utilization are primary issues not ...

Insights into vegetation and aboveground biomass dynamics within terrestrial ecosystems have come almost exclusively from ground-based forest inventories that are limited in their spatial extent. Lidar and synthetic-aperture Radar are promising remote-sensing-based techniques for obtaining comprehensive measurements of forest structure at regional to global scales. In this study we investigate ...

A ground-based, scanning, near-infrared (1064 nm) lidar, the Echidna® validation instrument (EVI), built by CSIRO Australia, retrieves structural parameters of forest stands rapidly and accurately, and by merging multiple scans into a single point cloud also provides 3-D stand reconstructions. Scans and field work in the USA (New England in 2007 and the Sierra Nevada of California in 2008) show...

always mazandaran province had been exposed to development and changes because of location in coastline of the caspian sea and having unique conditions. gis and remote sensing can be used to monitor in order to manage this sensitive province. then, this study is trying to detect land cover changes in coastal areas of mazandaran province using lcm. land cover changes detection have done using la...

economic and environmental logging is important for sustainable wood production in the caspian forests, north of iran. predetermination of the skid trail network and directional felling is a usual recommended method to reduce logging impact. the aim of this study was evaluation of directional felling and finding factors effective on felling error. totally 135 trees were selected randomly for di...

Above-ground forest biomass is a significant variable in the terrestrial carbon budget, but is still estimated with relatively large uncertainty. Remote sensing methods can improve the characterization of the spatial distribution and estimation accuracy of biomass; in this respect, it is important to examine the potential offered by new sensors. To assess the contribution of the TanDEM-X missio...
