Habitat Suitability Maps for Harpagophytum Species in Southern Africa

75.7 MB of data supporting environmental niche modeling for two medicinal plant species, Harpagophytum procumbens and H. zeyheri. The dataset includes cleaned occurrence records, environmental variables, model-tuning outputs, and final habitat-suitability predictions. It was created by Anthony Mapaura and last updated on April 20, 2026.

Use Cases

• Identifying potential cultivation hotspots for Harpagophytum species based on habitat-suitability predictions.
• Supporting conservation planning and zoning efforts using threshold-based classification maps.
• Reproducing or validating MaxEnt species distribution models using the provided model-tuning outputs.
• Analyzing the relationship between species occurrence and environmental variables documented in the dataset.

Strengths

• Includes multiple data components (occurrence records, environmental variables, model outputs) totaling 75.7 MB.
• Modeling process is documented as using MaxEnt (v3.4.1) with cross-validated tuning via ENMeval in R.
• Data is provided in multiple formats (CSV, R, TIF, TXT) for different analysis needs.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
