Extractive (i.e., the entire organism or parts of the organism are removed from its environment)
If extractive, for the target species, is this use
Lethal
Does this use involve take/extraction of
The whole entire organism
Details of parts/products taken
three different treatments were considered: stem-only harvesting, whole-tree harvesting (stem, tops and branches removed), and blading (whole-tree harvesting plus removal of stump and forest floor)
Is the use part of a strategy to generate conservation incentives, to finance conservation, or to improve tolerance/stewardship?
No
Is there evidence that the use is affecting the conservation status of the species? HIDE
Unknown/not recorded
Is there evidence that the use is affecting natural selection?
Unknown/not recorded
Is there evidence that the use is affecting poaching of illegal wildlife trade?
Unknown/not reported
Is there any evidence that this use of the species is having a knock-on effect on the status of non-target species
Yes, it is having a negative effect (e.g., prey depletion, stress, disrupted breeding, movement, sleeping, feeding patterns)
Yes, negative (e.g., it destroys/ degrades it due to over-use)
Additional Details (if available)
Springtails (Collembola) and oribatid mites (Oribatida), two dominant mesofauna taxa, have been identified as potentially good indicators of forest integrity due to their highly abundant and diverse communities in the soil and their roles in ecological processes such as litter decay (Petersen and Luxton, 1982; Neher et al., 2012) or physical microaggregation (Maab et al., 2015). Compared to mature uncut forests, soil mesofaunal communities remained modified 20 years after biomass harvesting, notably in the most intense practice (blading). Incomplete recovery of mesofauna was consistent with persistent modifications of soil environmental conditions in harvested plots, notably after blading. Modifications included a reduced organic cover (ground vegetation, mosses and woody debris) as well as lower organic soil thickness and moisture, which likely resulted in fewer suitable micro-habitats for many species;

Details of assessment carried out
recovery is incomplete within 20 years after intensive biomass removal in these boreal conifer-dominated stands, and is likely linked to stand development and associated processes. As a result, longer-term monitoring will be required to track mesofaunal community recovery through these later developmental stages.
absence of post-harvest recovery. It does need to be recognized that 20 years is a relatively short time frame in the life cycle of these forests which can easily reach more than 100 years be- tween two stand-replacing natural disturbance events such as wildfire
