Suitability-space species trait dataset for priority invasive alien plants (Ailanthus altissima; Acer negundo) in the Danubian riparian corridor
Listed in Teesside University Research Data Repository
Description Woody invasive alien plant species (IAS) can be characterised by their realised suitability niche derived from modelled associations between occurrences and environmental gradients.
Description
This dataset serves as a species trait database in the form of model-derived “suitability-space traits” (predictor–suitability association signatures), together with harmonised 1-km predictors, domain tables, and scenario-specific normalised suitability surfaces for the Danubian riparian corridor.
This enables users to fit alternative SDM model families, quantify predictor–suitability associations (“species suitability-space traits”), assess transferability across domains, and test bias-correction strategies using accessibility-linked predictors. The release contains: (1) an AOI polygon (Danubian riparian corridor extent); (2) screened environmental predictors aligned to a common 1-km grid in ETRS89-LAEA (EPSG:3035), provided as transformed (where relevant) and z-standardised rasters (mean 0, SD 1) with the scaling table; (3) species-specific occurrence bundles (Ailanthus altissima; Acer negundo) with three 1-km aggregated domain tables: Danube calibration data using a target-group background (TGB) design (presence vs TGB pseudoabsence; includes spatial CV fold IDs), and two independent evaluation domains (Romania and Serbia) with 1-km presence/absence tables.

All tables include a stable 1-km cell identifier (cell_id). (4) Scenario-specific PN suitability GeoTIFFs (Figs. S1–S8): each raster is probability-like normalised to sum to 1 within the Danube AOI.
PN GeoTIFF naming template PN_{species}_{scenario}_1km_EPSG3035.tif, where species ∈ {Ailanthus_altissima, Acer_negundo} and scenario ∈ {S1_baseline, S2_bias_aware, S3_romania, S4_serbia_riparian}.
