Understory Community Response to Two Invasive Prunus Species

60 vegetation plots across four forest canopy variants reveal that the invasive tree Prunus virginiana imposes stronger habitat effects than its congener P. serotina, reducing light and increasing litter. When both species co-occur, understory structure resembles that under P. serotina, suggesting a weakening of P. virginiana's stronger impacts and contrasting with invasional meltdown predictions. The dataset includes measurements of canopy openness, biomass, soil properties, and taxonomic, functional, and phylogenetic diversity of understory plants.

Use Cases

• Testing the invasional meltdown hypothesis based on comparisons of mixed and single-species invaded stands.
• Analyzing habitat engineering effects on understory communities using canopy openness, litter, and soil property data.
• Modeling functional trait filtering in plant communities under different invasive tree canopies.
• Comparing taxonomic, functional, and phylogenetic diversity metrics across native and invaded forest plots.

Strengths

• Includes data from 60 vegetation plots, providing a solid sample size for ecological comparison.
• Assesses understory communities across multiple dimensions: taxonomic, functional, and phylogenetic diversity.
• Released under a permissive CC-BY-4.0 license, facilitating reuse and sharing.

Limitations

• Column names and a precise row count are not provided in the available metadata, limiting immediate understanding of data structure.
• The dataset's spatial (geographic) coverage and specific time range of data collection are not specified.
• The last update date (2026-03-23) appears to be a future date, which is a conflict in the factual metadata.
