In subject area: Earth and Planetary Sciences Animals in the tropical rain forests where the species diversity is the highest in the world are characterized by the dominance of social insects (termites, ants, social wasps, and social bees), and the dominance of symbiotic associations. ...
Maximum values of harvested forest area and volumes of economic aggregates of forestry for each country are reported in the second and third lines of each label, respectively. Extended Data Fig. 8 Harvested forest biomass per year. Percentage of AGB harvested (expressed as relative amount of ...
We compared our numbers of area cover with the FAO statistics reported by each country. Here we group our results following the FAO definitions of “forest” and “other wooded land”, where “forest” is defined as areas >0.5 ha, with tree height above 5 m and a canopy cover of...
In 2017, Sarawak mandated that all of its Forest Timber Licence areas should obtain MTCS by 2022. 4.1.3.1. Implementation of Sabah Forest Policy 2018 We analysed the trends in Sabah’s FRs and TPAs over the years, and the size of its certified areas. Sabah’s total FR area pre-1963 ...
In addition to the APP reductions that are the focus of this study, the 2012 law reduces the area of forest protected by the “legal reserve” requirement (a percentage of each property that must be maintained as forest): although the required percentage remains the same, the APPs are now ...
spruce showed a non-significant loss of stem diameter and basal area increment at breast height of about 12 %. Similar reductions were reported for beech with −12 % for stem increment and −17 % for basal area. The height growth of spruce, however, significantly increased by 70 %, ...
pled sites with the lowest and highest basal area, which is likely the result of inaccurate allometric parameterization (Fig. 1). AGB is not uniformly distributed across forest types, with lowland forest having the highest stock on average, reaching ...
First, we estimated the population proportion of HRP in the study area, phrp, as the percentage of participants aged 15 years and older in each household survey—baseline, endline and MTAT—that fulfilled the HRP eligibility criteria. Sampling weights and the clustering structure of the respective...
Land transitions typically involved from 4% to 9% of each country’'s total area. The highest percentage of change in land cover is in Norway, followed by Finland, Sweden, and Denmark. The reduction of wetland in Norway and Finland made it the strongest net loss of a single class in ...
The impact of ash dieback on mortality rates was assessed by comparing mortality predictions based on pre-invasion inventories and later observations. Mortality was modelled by including basal area of the plot (BAplot) and tree diameter at breast height (dbh) (Table1). In the case of the grow...
