Sporobolus cryptandrus Invasion and Drought Response in Hungarian Grassland, 2022-2024

245.3 KB of vegetation cover data from a Pannonic sand steppe in Central Hungary, monitored over three consecutive years. The dataset, authored by Andrea Mojzes and published on figshare in 2026, tracks the frequency and abundance of the non-native grass Sporobolus cryptandrus and resident native species following an extreme drought in 2022.

Use Cases

• Modeling the relationship between extreme drought events and non-native plant invasion based on multi-year monitoring.
• Analyzing shifts in plant community composition based on percentage cover data for dominant perennial grass species.
• Investigating the competitive dynamics between Sporobolus cryptandrus and native species like Festuca vaginata and Stipa borysthenica.

Strengths

• Data spans three consecutive years (2022-2024), capturing temporal dynamics.
• Focuses on a specific, well-defined habitat: a Pannonic sand steppe, a priority EU habitat.
• Includes percentage cover data for dominant species and life forms, allowing for community-level analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred from the description sheet after download.
• The dataset's 245.3 KB size indicates a limited scope, likely from a single study site.
