With the ever growing population and economic needs of Mauritius, the flora of Mauritius has never been in more danger and one group of vascular plants is even more in peril; ferns.<em> Diplazium proliferum</em> is indigenous to the Mascarene region and is considered as a rare species in Mauritius. The need to develop a tested <em>in vitro</em> propagation protocol is a must to protect the biodiversity of Mauritius. This experiment was geared towards the establishment of a proper sterilization technique and the effect of 6-benzylaminopurine (BAP) and light on <em>in vitro</em> culture of this fern. Sterilization with 0.05% Mercuric chloride was effective to eliminate fungal contamination and allow germination of spores. Culture media supplemented with BAP did not significantly increase growth rate of both gametophytes and sporophytes of<em> D. proliferum</em>. Present results suggest efficient sterilization methods to be a crucial stage for successful<em> in vitro r</em>egeneration of ferns. The established protocol will be used as an optimized baseline protocol for the propagation of other indigenous ferns.

Steppe areas of the National Natural Park "Kremenets Mountains" occupy the minimum area in open hills and rocky niches, so the priority tasks are the protection of unique steppe ecosystems.Reproduction of steppe areas is one of the tasks aimed at preserving the diversity of steppe and petrophytic flora, the structure of cenoses in the steppe regions, as well as the habitats of rare steppe plants.The work is based on field research materials conducted during 2012-2018 on the territory of the National Natural Park "Kremenets Mountains". In the course of research, literary data and geo-botanical studies of the Strahov, Vovcha, Sokolina, Maiden cliffs and Zamkov mountains have been processed, flora and phytocenotic features of steppe and meadow-steppe phyto groups, the state and structure of rare species populations have been described.Characterized by the laws of distribution of steppe and meadow-steppe species of plants on the territory of the National Nature Park "Kremenets Mountains". The influence of natural conditions is described, factors which contribute to the decrease in the number of populations of these species are determined. The measures on preservation and reproduction of steppe ecosystems, preservation of the diversity of steppe and petrophytic flora, and the structure of the cenosis of the steppe regions are presented. The age structure of Adonis vernalis L., which grows on the Malyatyn and Vovchyna rivers, is studied.In order to preserve the populations of the listed rare steppe plant species, active measures have been taken within the framework of the National Natural Park "Kremenets Mountains", which consists in reducing the anthropogenic impact and restoring the settlement of rare species. According to the Territory Management Project, the state of afforestation of steppe areas is monitored, shrubs, undergrowth of trees and invasive herbaceous plants (in particular, Solidago canadensis L.) are cleared with which the steppe areas spontaneously grow; some measures are taken to increase the number of rare plants (repatriation).This will promote the expansion of steppe areas, the increase of the proportion of steppe and meadow species in the grassland and increase the area under the populations of individual rare species.

Classification scheme of rare habitats of Europe according to Bern Convention and Habitat Directive of EU was presented for the territory of Drevlianskyi nature reserve. It was shown significant habitat’s diversity of nature reserve from all main types of habitats — water (permanent and temporary lakes (waterbodies), watercources, reedbeds habitats), bog (eutrophic and mesotrophic mires), grassland (dry, mesic and wet grassland, floodplain and fen scrub, heaths), forest (leaved and conifer forests (woodland), rock (rocks and talus of silicate rocks). According to the results of field research, the territory of the reserve represented by 30 habitats (1 — ІІ leaves, 4 — ІІІ leaves, 25 — ІV leaves). It is established that the most common habitat 91T0 (Central European lichen Scots pine forests), which represented by 153 localities in A1C (dry pine forest) on an area of 421.5 ha. It was made a conclusion that the role of rare habitats in nature reserve Drevlianskyi is determinant for conservation of rare species of vascular plants that are protected by the Bern Convention, European Red List and included to the Red Book of Ukraine. The results of the analysis of the role of rare biotopes of Europe in the conservation of species of flora of different protection status on the territory of Drevlianskyi nature reserve show that most of the rare plant species of reserve listed in Resolution № 6 of the Bern Convention (Annex I), revised in 2011, are present in its rare settlements. The role of rare habitats of Drevlianskyi nature reserve in the conservation of rare species of flora is decisive — of the 29 species of plants of supranational and national levels of protection in rare habitats there are 24 species or 82.8% of their total number.

This article presents the data of population-biomorphological studies of the larkspur (Delphinium dictyocarpum DC.) in the Dzhungarskiy Alatau. Purpose of the research isto study the distribution, phytocenotic confinement, biomorphology and structure of Delphinium dictyocarpum populations. The studies were carried out on the territory of the Dzhungarskiy Alatau ridge in 2015–2017. The structure of cenopopulations (CP) was studied in 2 plant communities (descriptions 1, 2). To study the density and ontogenetic structure of cenopopulations in communities transects were laid, divided into areas of 1 m2 in size. The type of cenopopulations was determined according to two classifications of B.A. Yurtseva (1987, 1988) and L.A. Zhukova (2013). When studying the biomorphology and structure of cenopopulations, we used the principles and methods adopted in modern plant population biology developed by L.A. Zhukova (2012) and “Program and methodology...” (1986). The study revealed that Delphinium dictyocarpum in the Dzhungarskiy Alatau grows at an altitude of 1600 to 3200 m above sea level, occupying the upper third or the summit of the high mountains. On the slopes the species is found along the outcrops of rocks and on stony-gravelly areas in the composition of shrub-forb-livebeet, cereal-forb meadows. The species composition of live bunch communities is represented by 125 species of vascular plants from 95 genera and 37 families. The height of the above-ground organs of Delphinium dictyocarpum ranged from 115 to 250 cm.
