order to compare to tree cover at the plot level. We used different LiDAR minimum height thresholds ranging from 3 m to 7 m. While there were country-specific variations, the best correlation with the CHM was found with a 5–6 m threshold, indicating that the PlanetScope tree cover...
The selected model enhanced classification accuracy by increasing gradient mapping via RCU and modifying the size of convolution layers via LCU as well as reducing convolution kernels. To achieve this objective, a group of orthophotos were taken at an altitude of 260m for testing in a natural ...
Positive, null, or negative normalised values indicated absolute values that were respectively above, equal, or below the site mean value (see “Data handling and normalisation” in Methods). Our results showed that the SOC pool size (forest floor plus mineral soil layers) was negatively ...
interception of rainfall, absorption of light, uptake of gases, and provision of wildlife habitat), all plants contribute. Similarly, the forest environment changes continuously from top to bottom, so gradients cannot be subdivided objectively. In mixed-species, multi-aged stands, the upper layers ...
with some identifying a series of layers, classified on the basis of tree crown geometry and size, leaf size, and mass (seeBrunig, 1983). The best approach seems to be that ofWebbet al.(1972),who concluded that tropical forests should be considered on two levels of organization:vegetation...
Large accumulation of heavy metals in organic layers of forest soils may adversely affect the structure and diversity of microbial communities. The objective of this study was to assess the influence of different soil chemical properties on structure and diversity of microbial communities in soils pollu...

Superficial cultivation of soil layers could be included among those treatments, since this process aims to remove competing vegetation and logging slash, to facilitate planting or direct seeding [63], [64•]. MSP is carried out for many reasons: to promote natural regeneration, to reduce ...
the forest environment and the loose-knit nature of litter. By contrast, humus layers underlying fungal dominated litter layers can be dominated by bacterial biomass (Berg et al., 1998). The dryconditions of organic layers in forest soils generally favor fungi that tolerate desiccation better than...
