Satellite data is great for mapping big clearings, but misses the small-scale removal of the most valuable trees, for example by illegal loggers.
The extraction of the most valuable trees, such as Apé, reduces canopy cover and opens up paths into the forest that are often later used to start fires for illegal land clearance.
As a result of these treatments, an increase in tree diameter growth was obtained by ensuring better crown light exposure for the most valuable trees, consequently improving the quality of harvested wood.
This showed that carbon emissions from evergreen forests cut down in concession areas are almost ten times greater than those outside, confirming that it is the oldest and most valuable trees that are being targeted.
This approach contrasts with current selective cuttings that are used under the Chilean law, which do not control for residual stand structure, allow the harvest of 35% of the basal area per hectare in 5-year cutting cycles and preferably cut the most valuable trees instead of the worst (Donoso 2013; Schütz et al. 2012).
Currently, Tectona grandis is one of the most valuable trees in the world and no transcript dataset related to secondary xylem is available.
Mulanje cedar can reach 45 metres (148 feet) in height; it was once the most valuable timber tree of the genus, though it was later listed as a critically endangered species by the IUCN Red List of Threatened Species.
Teak (Tectona grandis Linn. f). is one of the most valuable timber tree species in the world.
One of the most important valuable tree species, which can be used for the composition of AFS in middle Europe is wild cherry (Prunus avium L). as it displays a rather fast growth and its timber can be of high value (Spiecker and Spiecker 1988; Balandier and Dupraz 1999; Morhart et al. 2014).
It is a large tropical tree with heavy-weight woods and, also, is one of the most valuable timber trees.
