Abstract

High quality data of botanical records, spatially and otherwise, can provide valuable information to researchers and government stakeholders in decision-making processes regarding species and habitat protection and sustainable use. Two plant databases were used as a source of records for assessment of spatial quality: Flora Croatica database (FCD) and Croatian Plant Genetic Resources Database (CPGRD). As the most extensive botanical database in Croatia, FCD comprises of herbarium collections, literature, and fieldwork observations aimed at nature protection, science, and educational use. CPGRD provides data on collection for conservation of national plant genetic resources in agricultural plant production and use. Dalmatian pyrethrum (Tanacetum cinerariifolium /Trevir./ Sch. Bip.) as an endemic and protected species with cultivation potential is an example of overlap in these two open databases. Records of Dalmatian pyrethrum were scored based on three categories of indicators: completeness, logical consistency, and positional accuracy. In total, 1042 records were identified (FCD: 901, CPGRD: 141) with 47 records found in both databases. Preliminary results indicate a high quality of Dalmatian pyrethrum spatial records scoring high on all three categories (completeness: 95.59%, logical consistency: 93.38% and positional accuracy: 95.78%). These findings open a possibility for linking the data from two different sectors while promoting constant quality improvements.
