Threatened Terricolous Lichen Observations from Ukrainian Red Lists

852 observations of threatened terricolous lichens compiled from multiple editions of the Red Data Book of Ukraine and the 2021 Red List. The dataset includes historical herbarium specimens dating back to 1921 and the last recorded observation of Cetraria aculeata on February 22, 2022. It was compiled by Olga Nadyeina and aggregates records from sources published between 1996 and 2021.

Use Cases

• Mapping the historical and current distribution of threatened lichen species based on the described observation records.
• Analyzing temporal trends in lichen biodiversity and conservation status using records spanning multiple Red List editions.
• Studying the impact of geopolitical events on biodiversity monitoring, as the description notes many locations are now occupied and records include pre-Holodomor settlements.

Strengths

• Includes 852 specific observation records of threatened species.
• Aggregates data from multiple authoritative conservation sources (Red Data Books of Ukraine from 1996-2021).
• Contains temporally deep records, including a herbarium specimen from 1921 and literature from 1842.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description notes a spatial bias, as many observation locations are now in occupied territories.
