Биотические аспекты геоэкологических исследований в целях инженерно-экологических изысканий

A theoretical review of publications containing information on the habitats of rare and protected plant species in the central and southern part of the Verkhnekamskoye salt deposit (Perm Krai) has been carried out. Information on the habitats of rare and protected plant and lichen species included in the Red Book of the Perm Territory and growing in the area is summarized. The insufficient amount of the available data required for engineering and ecological surveys has been shown. The need to carry out the special research to identify locations of protected plant, fungi and lichen species and to assess the status of their populations, initiated by the Ministry of Natural Resources, Forestry and Ecology of the Perm Territory, is consideredВыполнен теоретический обзор литературных источников, содержащих сведения о местообитаниях редких и охраняемых видов растений на территории центральной и южной частей Верхнекамского месторождения солей в Пермском крае. Обобщена информация о местообитаниях редких и охраняемых видов растений и лишайников, включенных в Красную книгу Пермского края, произрастающих на данной территории. Показана недостаточность имеющихся сведений, необходимых для инженерно-экологических изысканий. Обоснована необходимость выполнения специализированных научно-исследовательских работ по выявлению мест произрастания охраняемых видов растений, грибов и лишайников, по оценке состояния их популяций, инициированных Министерством природных ресурсов, лесного хозяйства и экологии Пермского края

Pteridophyte Distribution of the Urals and Adjacent Areas: a Dataset

Background Data on the species diversity and distribution of pteridophytes (lycophytes and ferns) in the Urals and adjacent areas are presented. The dataset includes 13,742 observations of two classes Lycopodiopsida and Polypodiopsida. In total, the dataset contains information on 16 families, 28 generas, 65 species, four subspecies and nine interspecies hybrids. All records are for lycophytes and ferns collected over 170 years between 1853 and 2021. The dataset presented is based on herbarium specimens, published data and field research conducted by the authors. This dataset is the first and important step towards generalising information on the current diversity and geographical distribution of pteridophytes in the Urals and adjacent areas. © Melnikov D et al.

Long-term ecology and conservation of the Kungur forest-steppe (pre-Urals, Russia): case study Spasskaya Gora

The Kungur forest-steppe is the northernmost outpost of European forest-steppe, located in the western pre-Urals within the boreal climatic zone. The co-existence of boreal, nemoral and steppe species with relicts and endemics results in a high plant diversity, making it an important biodiversity hotspot. Under current climate change and strong agricultural impacts, the Kungur forest-steppe is rapidly degrading. In order to develop sustainable management strategies, we studied the vegetation history over the last 3500 years in the natural reserve area Spasskaya Gora. Palynological data indicate that the territory of Spasskaya Gora was largely covered by hemiboreal forests with high proportion of elm during the late Holocene. An opening of the vegetation strongly correlates with erosion, both indicating anthropogenic activities such as lumbering, agriculture, grazing and hay making. The modern Pinus and Betula dominated forests combined with large areas dominated by grasses and herbs appear in the last 300 years and caused by human activity. The data support the ‘anthropogenic’ hypothesis of the Kungur forest-steppe development, suggesting that Pleistocene steppe was replaced by hemiboreal forests during the Holocene. Steppe elements survived on exposed rocks. The recent forest-steppe landscapes dominated by pioneer birch and poplar were formed due to anthropogenic deforestation. With respect to nature conservation, our data demonstrate that prohibition of any anthropogenic activities at Spasskaya Gora will lead to loss of diversity of steppe assemblages over the mid-term. We emphasize that conservation of the high plant diversity of the Kungur forest-steppe must include disturbance factors in the form of selective lumbering, prescribed burning, moderate grazing or traditional mowing

THE STUDY OF PLANT BIODIVERSITY ON ESPECIALLY PROTECTED NATURAL TERRITORIES OF PERM REGION

In 2002 the register "Especially protected natural territories of the Perm region" containing both maps of protected areas, and short descriptions of them was published. Analysis of the latter showed that on most protected areas the biodiversity of plants was not studied at all, and on the rest the survey was superficial. This circumstance intensified the study of biodiversity of protected areas plants by the authors. The vegetation cover of more than 30 protected areas from all Botanic-geographical regions of Perm region was examined; quantitative parameters of species composition are given in this publication. The main problems encountered when characterizing the vegetation cover protected areas are marked: involvement in the inspection of the vegetation cover persons without Botanical training; the lack of target financing of works on the study of biodiversity; a clear lack of analytical work on the species composition of plants in protected areas
