My objective was to use a time series of landsat images of Yellowstone National Park to track changes in above ground biomass and foliar nitrogen following the 1988 fire that burned about 36% of the park. To do this, I used field studies to correlate aboveground net primary production (ANPP) to a Normalized ...

Lidar remote sensing uses vegetation height to estimate large-scale above-ground biomass. However, lidar height and biomass relationships are empirical and thus often lead to large uncertainties in above-ground biomass estimates. This study uses vegetation structure measurements from field: an airborne lidar (Laser ...

Increased production of biomass for energy has the potential to offset substantial use of fossil fuels, but it also has the potential to threaten conservation areas, pollute water resources and decrease food security. The net effect of biomass energy agriculture on climate could be either cooling or warming, depending on the crop, the ...
By using the principles and methods of fractal geometry theory, the relationship between above ground biomass and plant length or sheath height of Carex lasiocarpa population was studied. The results showed that there was a good static fractal relationship between them, and the resulted fractal dimension was an efficient description of ...

Dynamic Vegetation Models (DVMs) simulate energy, water and carbon fluxes between the ecosystem and the atmosphere, between the vegetation and the soil, and between plant organs. They also estimate the potential biomass of a forest in equilibrium having grown under a given climate and atmospheric CO2 level. In this study, we evaluate the above ...

The Richards function was used to predict above-ground biomass and net primary production (NPP) for nine aspen stands situated on the Vilas soil series. Stands ranged in age from 8 to 63 years. Above-ground biomass and NPP ranged from 23 to 128 Mg ha/sup -1/ and 5.4 to 11.6 Mg ha/sup -1/yr/sup ...
Spatial patterns of forest composition, successional pathways, and biomass production were related to glacial landforms in a regional area of northwestern Lower Michigan. There were three general objectives: (1) to develop a geomorphic map of the study area, (2) to define and describe upland forest ecosystems, and (3) to study variation in species ...
Production increases in intensively managed forests have been obtained by improving resource availability through water and nutrient amendments. Increased stem production has been attributed to shifts in growth from roots to shoot, and such shifts would have important implications for below ground carbon sequestration. We examined above and below ground ...
