As indicated above, retention of a proportion of forest harvest residues (i.e. tops, branches, foliage) can reduce direct harvesting impacts. Other types of forest biomass can also be retained, including standing live or dead trees, pre-existing downed wood, the forest floor, and stumps and ...
EnMAP is planned for launch by the German Space Agency (DLR) in late 2020 or early 2021. It is also a new generation of VSWIR hyperspectral imaging system to provide high spectral resolution sampling at 5 to 20 nm per band (Fig.16) across the 400–2500 nm range with a pixel resolu...

Wood borers cause the most damage to trees by feeding on the phloem, cambium, and xylem as larvae, while adults will also consume some foliage. Adults are often attracted to stress volatile chemicals, sometimes within hours of a stress event occurring [139]. The overall time to tree mortality...
For structural vegetation survey, besides georeferencing, ground truth data are acquired by collecting structural data such as plant height and population count [32]; tree height and crown cover diameter for each tree [108]; tree girth [109] or foliage, seed/flower/fruit, branching and bark ...
