To overcome this issue, we combined spectral information from Sentinel-2A multispectral imagery with 3D structural information from high-density point clouds of airborne laser scanning (ALS) imagery to map old-growth forests over an extended area. Four features from the ALS data and fifteen from ...
" says UVM's Bill Keeton, who has studied forests in Europe for more than a decade and chairs a working group on old-growth forests for the International Union of Forest Research Organizations. But the new study also shows that the preservation of these remaining fragments of primary...
but with substantial error in high-resolution estimates. There does not seem to be a readily-available method to map mature and old-growth stands across a landscape with a high degree of accuracy. Identifying mature and old growth forests in a stand management context will likely require addition...
To help educate and share the value in conserving our old-growth forests, please scroll through this story map to learn more about their importance for biodiversity and where you can find some of these hidden gems in Nova Scotia. 01 / 04 Sources: Esri, TomTom, Garmin, FAO, NOAA, USGS,...
Old-growth forests are irreplaceable with respect to climate change mitigation and have considerable carbon (C) sink potential in soils. However, the relationship between the soil organic carbon (SOC) turnover rate and forest development is poorly understood, which hinders our ability to assess the...
Impressive sink holes fill this untouched old-growth forest in the Bahamas. Asque, France Gourgue d'Asque A French valley with forests so lush it was nicknamed "the Small Amazonia of the Pyrenees." Whitethorn, California Enchanted Forest ...
The concept of the old-growth forest is highly debated in the literature because of its implications, from close-to-nature forest management to carbon balance. Studies on old-growth forests have multiplied in the last three decades. Most of these studies have focussed on defining the structural ...

The move to cut down old-growth forests is also of concern to tourist business operators in the region who contend that the standing trees have a far greater value than the clear cut lumber they will provide. “Port Renfrew, a former logging town, has successfully re-branded itself in...
This study indicates that if a detailed topographic map can be made, the canopy height profile derived from aerial photography can be effective in analyzing the canopy structure of evergreen forests, such as tropical rain forests, over large areas. 展开 ...
