Vietnam 200 endemic and/or endangered plant species

Study Extent

All the vascular plant specimens collected in the period from 2007 to 2020, archived in the Hanoi Herbarium (HN), especially the ones collected in the frame of the national project 'ĐTĐL.CN-58/19' have been considered.

Sampling

The transect method has been used during the field study of the projects that produced the specimens for our dataset. The transects have been established through most typical habitats so that as many as possible plant species could be encountered during field surveys.

Quality Control

The specimen have been taken only when all necessary organs can be found, processed and archived using most advanced methods for long term use

Method steps

1. The field surveys of the national project 'ĐTĐL.CN-58/19' have been conducted in 2019-2020. The specimens have been processed, identified and archived in the Hanoi Herbarium (HN). The project also examine and choose the appropriate specimens collected during previous projects and archived in the Hanoi Herbarium (HN) to create this dataset. The specimens were selected to use for this dataset based on the availability of digital pictures of fresh specimens and all other information needed. The information on the specimen has been taken for creating records. In the case when the coordinates have not been given in decimal system we used the 'Canadensys' system to convert the data.
2. the created dataset has been checked with using Open Refine software and GBIF tools (data validator, species matching) and corrected if needed until no error has been reported

The specimens of the dataset belong to five plant classes (Lycopodiopsida, Polypodiopsida, Pinopsida, Liliopsida, Magnoliopsida), that belong to the phylum of vascular plants (Tracheophyta) of the Plantae kingdom.
