Kricsfalusy; email: [email protected] INTRODUCTION Biodiversity assessment comprehensive analysis of studies requires precise data about on biogeographical patterns and species distribution that are various environmental questions lacking for many areas because where herbarium collections they are often incomplete or have been successfully used, biased12. Recently, many studies refer to Lavoie12. In most cases are turning to the vast amount herbarium data provide error-free of information associated with information5. However, because of the natural history collections, its existing limitations2, additional particularly herbaria. Herbarium sources of information are data are useful for biodiversity required to assist in biodiversity exploration34, identification assessment and conservation of species of conservation planning. concern5, development of regional red lists6, prioritizing of Although mostly ignored until now, rare species for conservation freely accessible citizen science planning78, documenting effects phenology databases, which have of urbanization on flora9 as well as advanced intensely during the last assessment of spread and status decades, might be another source of invasive species1011.

PlantWatch enables obtained from different sources, citizen scientists to get involved i.e. herbarium collections, in research by recording flowering phenological database and field times for selected plant species surveys, often do not have the and reporting these dates to same level of accuracy17. This is databases or researchers. mostly because they were collected Based on the evidence of high using different approaches, i.e. effectiveness of the PlantWatch the traditional ad hoc method program13, the phenological versus systematic survey. Also, records from the regional distribution data often were databases like the Saskatchewan recorded before the widespread PlantWatch15 might be a good use of global positioning systems data source about plant species (GPS), particularly the older data distribution. in herbarium collections, and therefore in many cases cannot Field observations and surveys, be georeferenced with a high recorded in the form of vegetation level of accuracy. The combined releves, also provide valuable analysis of data obtained from data for biodiversity assessment; different sources may minimize however they are not often used the biases associated with each of for distribution analysis.
