“…As we have shown, this significantly underestimates the proportion of AGB (by 15.1 ± 3.9% in our case) stored in a forest, and as we are interested in total coarse wood productivity , they should be included in estimates. Hedl et al (2009) also found that small stems comprised as much as 50% of the stems in a stand, and Djomo et al (2011) found an average 8% of the carbon current annual increment was in this size class. Quite how many stems are in this small size class is dependent on the successional age of the stand, but in most instances these small stems contribute significantly to the carbon pool (Brown, 2002).…”

“…All cored trees of the four study species, together with individuals (>10 cm DBH) of all species within a 10‐m radius, were mapped with the Field‐Map technology (Hédl et al . , http://www.fieldmap.cz/) so that all mapped trees defined each site. The stumps of recently felled trees (those estimated to have been cut in the last 5 years) were also mapped.…”

* Most experimental evidence on the relationship between biodiversity and ecosystem functioning comes from ecosystems with fast-growing plants, such as grasslands. Although forests provide essential ecological services, they have been less well investigated. * We used dendrochronology to compare the tree radial growth rates of four important timber species in replicated, spatially mapped stands that differed in tree composition and diversity within a central European managed forest. * Growth rates differed among species but were largely unaffected by the density of neighbouring trees. * Increasing stand diversity enhanced individual growth rates, after accounting for the effects of tree density and size. These increases were statistically indistinguishable among the four species. In contrast, the effects of stand and neighbourhood species composition on growth rates were non-significant. * Policy implications. Our study of long-established central European forest stands revealed levels of tree diversity can be increased in managed forests, with the potential for modest increases in tree growth rates. These results suggest that in addition to the biodiversity and risk mitigation benefits associated with shifting practices away from monoculture management, increased carbon sequestration and yields in mature forests are likely to be realized. Our results suggest that it is possible to increase forest diversity with little or no costs to production and even with the potential for modest increases in tree growth rates

“…October 2016. Stem and crown positions were measured with decimetre spatial precision following the ground-based laser method (Field-Map technology, IFER, Czech Republic, https ://www.field map.cz/) described in Hédl et al (2009). Between 5 and 30 points were recorded for each crown and smoothed spatial polygons were fitted to these.…”

Logging, pervasive across the lowland tropics, affects millions of hectares of forest, yet its influence on nutrient cycling remains poorly understood. One hypothesis is that logging influences phosphorus (P) cycling, because this scarce nutrient is removed in extracted timber and eroded soil, leading to shifts in ecosystem functioning and community composition. However, testing this is challenging because P varies within landscapes as a function of geology, topography and climate. Superimposed upon these trends are compositional changes in logged forests, with species with more acquisitive traits, characterized by higher foliar P concentrations, more dominant. It is difficult to resolve these patterns using traditional field approaches alone. Here, we use airborne light detection and ranging‐guided hyperspectral imagery to map foliar nutrient (i.e. P, nitrogen [N]) concentrations, calibrated using field measured traits, over 400 km2 of northeastern Borneo, including a landscape‐level disturbance gradient spanning old‐growth to repeatedly logged forests. The maps reveal that canopy foliar P and N concentrations decrease with elevation. These relationships were not identified using traditional field measurements of leaf and soil nutrients. After controlling for topography, canopy foliar nutrient concentrations were lower in logged forest than in old‐growth areas, reflecting decreased nutrient availability. However, foliar nutrient concentrations and specific leaf area were greatest in relatively short patches in logged areas, reflecting a shift in composition to pioneer species with acquisitive traits. N:P ratio increased in logged forest, suggesting reduced soil P availability through disturbance. Through the first landscape scale assessment of how functional leaf traits change in response to logging, we find that differences from old‐growth forest become more pronounced as logged forests increase in stature over time, suggesting exacerbated phosphorus limitation as forests recover.
