Red Data Updates for Orenburg Oblast
One of the ways to study and protect flora is keeping and publishing regional Red Data Books. A floristic study resulted in a series of data on the flora of Orenburg Oblast, which made it possible to make a set of criteria for updating the list of regional species for conservation. In early 2018, the authors proposed 6 species of vascular plants to be registered in the Red Data Book of Orenburg Oblast including Stipa zalesskii Wilensky, Iris aphylla L., Botrychium lunaria (L.) Sw., Pedicularis palustris L., Saxifraga sibirica L., Salvia glutinosa L. The registration of some of them in the Red Data Book was recommended in view of an increased anthropogenic adverse impact on their habitats and a growing threat of extinction. On September 2018, the proposed Red Data updates for Orenburg Oblast outlined in this article were adopted and approved by the Government of the Orenburg Oblast.
