The species of this family are facing tremendous pressure due to habitat degradation, overexploitation and changing environmental conditions. Therefore, while exploring the floristic diversity of NUPA, attempts were made to explore the orchid diversity, distribution patterns, nativity, endemism, threat categories, and local uses.

Strobilanthes lamiifolia (Nees) T. Anderson is reported here as a new record for the flora of Vietnam. It is morphologically allied to Strobilanthes sulfurea but differs in the shape of the leaf, bract, and bracteoles. Photographs and line drawings are given together with information on habitat, ecology and preliminary conservation assessment based on IUCN criteria.

Climate aridization and increased anthropogenic pressure pose a severe threat to natural vegetation, including coastal plant communities. Those located in river basins of the desert zone of Central Asia are among the most vulnerable. Of the variety of ecosystems of the Ili-Balkhash region of Kazakhstan, forests dominated by a rare relict species Populus pruinosa Schrenk are of particular concern. This species occupies a very narrow ecological niche associated with river banks of the arid zone, which makes it very vulnerable to adverse natural and anthropogenic factors.

This study addresses the question of how changing the mowing regime influences the floristic composition and floristic diversity of grasses in an experimental lowland meadow. The study location is Białowieża Forest, NE Poland. To achieve the aim we used phytosociological data from long-term studies in Białowieża Forest on the course of secondary succession. The relationship between the biodiversity of grasses and type of mowing was determined using statistical analysis. Changes in the dominance and frequency of individual grass species have occurred during the last 28 years of observations.

Species distribution patterns, community structure, and dynamics are determined on a small scale by soil and habitat heterogeneity. The aim of this work is to evaluate the temporal changes in composition and structure of a tree community, revealing the ecological drivers of the observed vegetation patterns. For 16 years (2000, 2005, 2010, and 2016) we monitored the temporal variations in structure and floristic composition of a semideciduous seasonal forest through 20 × 20 m2 (400 m2 ) plots, totaling 2.08 ha of sampled area encompassing Cambisol (0.4 ha), Oxysol (1.12 ha), and Nitosol (0.

Open-cast mining in tropical forests causes negative impacts on biodiversity and carbon storage. Postmining reclamation is therefore imposed to recover the vegetation despite the lack of understanding which indicators can be used to monitor the progress ofsuccession. This study proposes an integrated framework to assess the trajectory of vegetation succession in coal mining site in East Kalimantan, Borneo.

The field study was conducted to investigate weed flora diversity in rice crop during kharif season of 2020-21 in four development blocks viz. Naraini, Mahua, Badokhar Khurd and Baberu of Banda District in Uttar Pradesh State. This study identified and quantified the floristic composition of weeds in four different blocks. The number of monocot species recorded in the study was 13 (68 %), while the number of dicot species was 6 (32%). Out of 19 weed species 9 were annual...

The present study was conducted to assess the floristics, structure and diversity of dry tropical forests in buffer zone of Achanakmaar-Amarkantak Biosphere Reserve. The biosphere is well recognized for its species richness and biological diversity. However, the increasing anthropogenic activities are causing rapid degradation of native ecosystem, especially the buffer and transition zones are severely affected and becoming ecologically fragile by disappearance of many valuable species. A line transect survey was conducted for inventorying floristic composition.

Six different A. catechu bearing forest types including one plantation of A. catechu were selected for phytosociological studies in the Western Himalayan region of India. 72 sample plots of 0.1ha were selected. The plant genetic spectrum was made up of 75 genera with 86 species belonging to 43 families. Vegetational analysis revealed that in Dry Shiwalik Sal forest, the dominant tree species was Shorea robusta while in Northern Dry Mixed Deciduous forest, Dry Deciduous Scrub forest and Dry Riverine forest, the dominant tree species was Acacia catechu.

The objective of this study is to measure the floristic diversity in coffee agroforests and adjoining forests as well to know the effect of different landholding sizes of coffee farms in Kodagu district, Western Ghats of Karnataka. We collected the data on trees, shrubs and herbs from 50 sample plots of 0.16 ha. Each and analyzed for various diversity parameters. Results revealed that Shannon’s (H') was highest in adjoining forests (2.48) compared to that of coffee agroforests (1.92). On the other hand, Simpson’s (D) value recorded in adjoining forests lower (0.

The purpose of this study is to quantify the floristic diversity in forests and coffee agroforests and to know the effects of different landholding sizes in Kodagu district of India's the Western Ghats. We collected the data on trees, shrubs and herbs from 50 sample plots of 0.16 ha. each and analyzed for various diversity parameters. Results revealed Shannon’s (H') was highest in coffee agroforests (3.60) compared to that of natural forest (3.32). Conversely, Simpson’s (D) values did not differ between the land-use types.

The floristic composition and phytogeographical analysis of the Gebel Elba National Park in the south-east corner of Egypt were studied using multivariate analysis techniques. Its flora was poorly documented; therefore, 5 recent expeditions between 1998 and 2004 were carried out, which resulted in the collection of 179 species that belong to 51 families.

This study aimed to characterise Egyptian desert vine flora and compare it with that of deserts in other continents, such as Australia and North America. Specifically, 5 common climbing desert plants (Citrullus colocynthis, Cocculus pendulus, Cucumis prophetarum, Pergularia tomentosa, and Periploca angustifolia) were selected for this study.

The species diversity in the natural reserves increases from the Black Sea coast to the east, a movement that corresponds to a similar increase in altitude. In this study, 3 floristic groups are recognized: mountainous areas, lowlands, and piedmonts. The most speciesrich communities are found in extreme environments.

The plant diversity of southern peninsular India has recently been reduced to a great extent due to anthropogenic disturbance and environmental degradation. Disturbance was the major factor responsible for fragmentation of forest vegetation; as a result of this, there is a preponderance of small patches, some of them still preserved as sacred groves because of strong religious beliefs held by the indigenous people of this region.
