Description
This dataset contains the data on the herbarium deposited in the Nature Reserve "Roztochya" (Lviv Region, Ukraine). It is mostly focused on the specimens collected from the regional flora by Igor Khomyn in the 2000s, but also contains other related occurrence records.
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 968 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Sampling Methods
The specimens of vascular plants deposited at the herbarium YAV were digitized using a Lumix G9 camera with an Olympus 35 mm Macro lens. The pixel-shift mode has been applied to obtain the highest possible resolution. The data were extracted from the labels using the captured photos and organized in a Darwin Core dataset.
| Study Extent | The study includes the specimens of vascular plants deposited at the herbarium of the Nature Reserve "Roztochya" (YAV). It mostly covers species and infraspecies representing modern regional flora (1997-2014). There are also some specimens collected from other areas of the western part of Ukraine. |

| Quality Control | The data were checked manually using MS Excel and then additionally checked using OpenRefine software. |
Method step description:
- The herbarium specimens were labeled with barcodes and digitized using the stationary photosystem built with a Lumix G9 camera with an Olympus 35 mm Macro lens. The images in RAW (archival master files) and JPEG (operating files) formats were produced simultaneously. Obtained images in JPEG format were cropped and post-processed using MS Office Picture Manager software, and, after that, renamed following the applied barcodes using BCRWatcher software. The data from the labels has been extracted manually using MS Office Picture Manager software and organized in an MS Excel table following the Darwin Core standard. After that, the data has been harmonized and enriched with coordinates and other supporting information. The final dataset has been cleaned using Open Refine software and converted to a TSV format.
