CT: Forest residues consist of small trees, branches, tops and un-merchantable wood left in the forest after the cleaning, thinning or final felling of forest stands, used as fuel without any intermittent applications. Three main sources of forest residues can be distinguished: slash from final fellings, slash and small trees from thinnings and cleanings, and un-merchantable wood. In Sweden for example, slash from final fellings constitutes the largest share (over 71% in 1996 and even more dominating in 2003).

N: 1. forest (n): late 13c., “extensive tree-covered district,” especially one set aside for royal hunting and under the protection of the king, from Old French forest “forest, wood, woodland” (Modern French forêt), probably ultimately from Late Latin/Medieval Latin forestem silvam “the outside woods,” a term from the Capitularies of Charlemagne denoting “the royal forest.” This word comes to Medieval Latin, perhaps via a Germanic source akin to Old High German forst, from Latin foris “outside” (see foreign). If so, the sense is “beyond the park,” the park (Latin parcus; see park (n.)) being the main or central fenced woodland.
Another theory traces it through Medieval Latin forestis, originally “forest preserve, game preserve,” from Latin forum in legal sense “court, judgment;” in other words “land subject to a ban” (Buck). Replaced Old English wudu (see wood (n.)). Spanish and Portuguese floresta have been influenced by flor “flower.”
residues (npl): From residue, mid-14c., from Old French residu (14c.), from Latin residuum “a remainder, that which is left behind,” noun use of neuter of adjective residuus “remaining, left over,” from residere “remain behind” (see reside).
2. forest residues: In the fields of Silviculture, Forestry Operations and Biomass Energy, unused wood in the forest including logging residue; rough, rotten, and dead trees; and annual mortality.
forest waste: The term “waste” is considered to be an uncountable noun; however, it is often found in the plural form (wastes), particularly when speaking of different types of waste.
3. In the field of Forestry Operations, the usual term is “slash” (also “logging slash” and “brash”): The unused residue after logging, e.g. logs, uprooted stumps, broken or uprooted trees, branches, tops, bark and chips, left on the area …
According to Terminology of Forest Science, Technology Practice and Products, “brash” is used in the United Kingdom.
