The objective of this study is to test the feasibility of nation-wide medium footprint airborne laser scanning (ALS) data for derivation of forest parameters. The comparison of canopy closure as one important parameter for many forest functions derived from ALS data and aerial photo interpretation was conducted. The present study was carried out in the framework of the Swiss National Forest Inv...

Carbon and water fluxes in ecosystems are tightly coupled by gas diffusion through stomata. However, carbon–water (C–W) relationships vary largely across time scales, vegetation types, regions. Subtropical forests China play an important role the global carbon cycles, yet studies of C–W this region remain limited. Here, we investigated summer-time at two subtropical sites: evergreen broadleaved...

Primary forest conversion greatly influences soil organic carbon (SOC) sequestration. However, our understanding of how primary affects SOC fractions and chemical component evenness remains limited. We examined (from mixed broadleaved Korean pine to secondary coniferous plantation) free particulate OC (POC), aggregate-occluded POC, mineral-associated (MAOC), their via plant inputs (e.g., litter...

Accurate and efficient estimation of forest volume or biomass is critical for carbon cycles, management, the timber industry. Individual tree detection segmentation (ITDS) first key step to ensure accurate extraction detailed structure parameters from LiDAR (light ranging). However, ITDS still a challenge achieve using UAV-LiDAR (LiDAR Unmanned Aerial Vehicles) in broadleaved forests due irregu...

Dieback in temperate forests is understudied, despite this biome predicted to be increasingly affected by more extreme climate events a warmer world. To evaluate the potential drivers of dieback we reconstructed changes radial growth and intrinsic water-use efficiency (iWUE) from stable isotopes tree rings. Particularly, compared size, radial-growth trends, responses (temperature, precipitation...

The pine wood nematode (PWN) is an invasive species which was introduced into Europe in 1999. It represents a major economic and ecological threat to European forests. In Europe, the maritime main host Monochamus galloprovinciallis its only vector. Our goal analyze effect of landscape heterogeneity on vector’s dispersal. We further aimed at developing new method locate origin insects captured s...

In order to comprehend detailed forest resources, the use of high spatial resolution data is expected. However, the efficeint forest cover type classification method of high spatial resolution data is not cleared yet. So, this study discussed the potential of the forest cover type classification such as classification of coniferous forest, broadleaved forest, and mixed forest, and tree speices ...

Abstract Context In the last century European forests are experiencing tree damage and mortality rise it is expected to continue due increased disturbances under global change. Disturbances generally creates canopy gaps, which leads secondary succession, compositional changes landscape mosaic transformations. Forest gap characterization has traditionally been performed in light-limited tropical...

Wild ginger (Hedychium gardnerianum) is a tall rhizomatous herb that invades forests and shrubland fragments in northern New Zealand. In order to determine the impacts of this invasive weed on forest processes, comparisons of conifer-broadleaved forest patches with different densities of ginger were made at Opononi and Whangarei in Northland. Soil properties, vegetation structure, floristics, a...
