چکیده

In the present study, the aboveground biomass of the understorey vegetation of boreal coniferous forests was modelled according to the percentage cover. A total of 224 observations from 22 stands in upland forests and 195 observations from 14 different studies in peatland forests were utilized for the present analyses. The relationships between biomass and percentage cover can be used in ecosystem and carbon-cycle modelling as a rapid nondestructive method for estimation of the aboveground biomass of lichens, bryophytes, herbs and grasses, and dwarf shrubs in upland forests and bottom and field layers in peatland forests.

Biomass Estimation for Boreal Forests Using Field, Lidar and L-band Sar Data

The coupling of LIDAR and SAR for vegetation structure has been investigated in several terrestrial biomes [7, 4, 6]. In this paper, we explore the measurement of biomass in boreal forests. This ecosystem was selected since the boreal biome is environmentally important, yet significantly under-sampled. The boreal forest biome consists of a circumpolar region lying above 50o–60o latitude and ext...

Effects of recreational use and fragmentation on the understorey vegetation and soil microbial communities of urban forests in southern Finland

The impacts of fragmentation and recreational use on the hemiboreal urban forest understorey vegetation and the microbial community of the humus layer (the phospholipid fatty acid (PLFA) pattern, microbial biomass and microbial activity, measured as basal respiration) were examined in the greater Helsinki area, southern Finland. Trampling tolerance of 1) herb-rich OMT, 2) mesic MT, and 3) sub-x...

Understorey bird responses to the edge-interior gradient in an isolated tropical rainforest of Malaysia

Forest fragmentation results in a loss of forest interior and an increase in edge habitat. We studied how understorey bird community composition and habitat variables changed along an edge-to-interior gradient in a 1248-ha lowland rainforest patch in peninsular Malaysia. Birds and environmental variables such as vegetation structure and litter depth were detected within a 25-m radius of each of...

Regional paleofire regimes affected by non-uniform climate, vegetation and human drivers

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 20090-2010 Uavsar Campaign to Map Vegetation 3d Structure and Biomass

We present the results of the 2009-2010 UAVSAR campaigns over boreal, temperate and tropical forests. UAVSAR is a new L-band fully polarimetric synthetic aperture radar (inSAR) capable of repeat pass interferometry (Figure 1)[1]. Our objective is to estimate vegetation 3D structure and biomass using polarimetric backscatter, repeat-pass inSAR, lidar and ancillary data (e.g. land cover maps, cli...
