Figure 1 Maps of the field sites A country boundaries of South America with the Amazon Basin indicated by the heavier outline B Ecuador with the locations of TBS as a red circle and the boundaries of Yasuní National Park shaded C a DEM of the study area. The 24 sampling sites are indicated, with blue squares representing FP forest sites and green circles for TF forest. Latitude and longitude (in DD) shown along x and y axes. Maps generated through R packages: 'raster' (Hijmans 2015), 'sp' (Pebesma and Bivand 2005; Bivand et al. 2013), 'GISTools' (Brunsdon and Chen 2014), and 'maps' (Becker et al. 2015).

Figure C3 Morphospecies relative abundance by the number of sampling sites at which they were present. Point markers represent the 143 morphospecies coded according the three rarity categories: 'dominant' (circle), 'common' (triangles) and 'rare' (diamonds). Morphospecies classified as 'dominant' occurred at a higher number of sampling sites than 'common' morphospecies. 'Common' morphospecies occurred at a higher number of sampling sites than 'rare' morphospecies (P < 0.001).

Figure 2 Carabid beetle rarefaction curves. Interpolation (solid lines) indicated by filled point markers represents the sampling extent of the current study. Extrapolation curves based on the Chao1 nonparametric diversity estimator are shown (dashed lines). Shaded areas depict unconditional 95% confidence intervals A the overall dataset with both forest types combined and richness extrapolated to n = 2,510 (twice the number of individuals collected) B rarefaction curves for FP forests (blue square) and TF forests (green circle) with sample size extrapolated to n = 1,128 (twice the number of individuals collected in FP forests). FP forests (96 ± 8.0) were significantly more species rich than TF forests (72 ± 8.1) at the rarefied sample size (n = 564). The extrapolated rarefaction curves suggest the difference in cumulative morphospecies richness between FP and TF will decrease as sample size increases.

Open data for assessing habitats degree of conservation at plot level. An example dataset of forest structural attributes in Val d'Agri (Basilicata, Southern Italy)
<p>We provide a georeferenced dataset of vertical and horizontal structure of forest types belonging to 4 habitat types, sensu Council Directive 92/43/EEC. The dataset includes structural indicators commonly linked to old-growth forests in Europe, in particular the amount of standing and lying deadwood. We collected data on 32 plots (24 of 225 m<sup>2</sup>, and 8 of 100 m<sup>2</sup>, according to different forests type) during spring and summer of 2022, in Val d’Agri (Basilicata, Southern Italy). The dataset we provide follows the common national standard for field data collection in forest habitat types, published by ISPRA in 2016 (https://www.isprambiente.gov.it/public_files/direttiva-habitat/Manuale-142-2016.pdf) with the aim to promote a greater homogeneity in assessment of habitat conservation status at Country and biogeographical level, as requested by the Habitats Directive.</p> <p>Data were acquired by using a free Android application (VegApp, (https://vegapp.de/), and standardized field survey forms.</p> <p>The selection of the location of the sample sites were spatially balanced by using the sofware QGis vers. 3.22 (http://qgis.osgeo.org)</p> <p>plots_Table1 shows the characteristics of the sample sites, and information on type of management, when available.</p> <p>plots_Table2 provides the description and the measuring unit of all the attributes included in the dataset at plot level. It includes parameters used for assessing old-growth forests, linking them to the main type forests management, in order to both select indicators useful for assessing the conservation degree of forest habitat types, and identify good practices for nature conservation in these ecosystems.</p> <p>plots_Table3 contains information on living trees and deadwood at plot level.</p> <p>Trees describes the dataset related to single-tree data, and it contains the following fields for all living trees, exceeding 10 cm DBH, occurring in the plots. The nomenclature follows the Italian checklist available at https://dryades.units.it/floritaly/</p> <p>The shapefile "plots" contains the same information included in plots_Table1.</p>
