Salix Genus Herbarium Specimens from the Ural Region Over 150 Years

Over 150 years of plant specimen records for the genus Salix (willows) collected in Europe and primarily the Ural region. The data was compiled by Nickolak Erokhin from the SVER Herbarium at the Institute of Plant and Animal Ecology, Ural Branch of the Russian Academy of Sciences. Each record includes geographic coordinates with approximately 1 km accuracy and a high-resolution 600 dpi digital image of the herbarium specimen and its label.

Use Cases

• Modeling historical species distribution based on georeferenced occurrence data.
• Training image classification models on high-resolution scans of herbarium specimens.
• Studying temporal changes in plant biodiversity over a 150-year period.
• Conducting taxonomic research on the Salix genus using verified specimen records.

Strengths

• Specimens collected over a 150-year time span, providing long-term ecological context.
• Each occurrence is linked to geographic coordinates with an approximate accuracy of 1 km.
• Includes a high-resolution 600 dpi digital image for every herbarium specimen and its label.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale ML tasks.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the collection focus on the Ural region.
