The study is based on intensive survey of relevant literature which reviews the present status, threats, conservation initiatives and major legislation related to conservation of forest ecosystems and plant diversity. The three natural forests (Hill, Sal and mangrove forest) are the key habitats of plant diversity and cover about 2 million hectares of land. Despite a flora diversity rich country, the existence of many plant species is currently under threat as evident by continuous degradation of natural forest in Bangladesh. There is an increasing pressure on the biodiversity of this country to meet the needs of the increasing population of Bangladesh. As a result, many plant species are gradually declining and are facing extinction. Over exploitation of natural ecosystems, land use changes, permanent infrastructures in natural ecosystems, illegal logging, natural disasters, climate change effects and limited forest protected areas (FPAs) are key threats to plant diversity. Government has made some initiative to conserve the remaining plant diversity including declaration of FPAs, national conservation strategies and establishment of environment related acts. At present 47 FPAs are established as in-situ and ex-situ conservation approaches to preserve plant diversity. Several preservation plots, clone banks and arboreta are also functioning as conservation approaches. The country has several laws that address forest and biodiversity conservation, several of which has been amended in last decade. Recently the country has taken some policies and projects in small scale to ensure effective conservation of plant diversity through sustainable management practices. Although co-management by FPAs authority and local participant has some advantageous effects, the existing conservation practices are still poor to effective conservation of flora diversity.

The study considers the issues of introduction and reintroduction of the Red Book species of checker tree in the system of decorative gardening, forest protection, and forest ecosystems. That is why the purpose of the study was to monitor the green corridors of rural and urban ecosystems of the forest-steppe zone of Ukraine, to investigate and select the best forms of checker tree in terms of morphological characteristics and physiological properties for promising areas of distribution and conservation in the form of pure and mixed plantings. The following methods were used in the research: route, field, biometric, laboratory, comparative analysis, mathematical and statistical. New forms of checker tree were introduced, studied in in situ and ex situ conditions, and selected for the prospects of their further introduction and reintroduction into the ecological network of Ukraine and conservation to activate trophic, phoric, and other types of biotic interactions in a single territorial ecosystem. Sparsely distributed biotypes of Torminalis glaberrima (Gand.) Sennikov & Kurtto f. Intermedia Kossetz were found in the zone of green corridors of rural and urban ecosystems of the forest-steppe zone of Ukraine. Some specimens of these biotypes were identified as valuable material for introduction into the system of fruit and ornamental gardening, including parks and monuments of landscape art, as well as natural monuments, protected tracts, sanctuaries and reserves of pure and mixed plantings, alleys, forest reclamation strips, etc. It was established that the elements of originality of the selected forms of checker tree – Eva, Podolianochka and Slavka – are the specificity of the crown shape, which determines the level of productivity, small and medium growth force, normal reaction to pruning (which affects the size and yield of fruits), high degree of flowering (60-80%), increased fruit size (diameter of more than 2 cm), increased fruit weight (1.8-2.1 g), increased number of fruits on the stem (≥20 units), a pleasant and harmonious taste of fruits, high quality of fruits, lack of periodicity in fruiting in nature and in culture, high xenogamy (69-75%), high yield of fruits from the plant, increased winter hardiness (7.5 pt.), high drought resistance (8 pt.) and resistance to pests, including pear leaf blister mite (7-9 pt.). The findings can be used in the future to replenish pure and mixed plantings in the ecological network of Ukraine

“…Khasis are the aboriginal inhabitants of the Khasi-Jaintia Hills who migrated westward and encroached upon the Khasi-Jaintia Hills (Bhattacharjee, 1984). Even though the exact time of Khasi-Jaintia Kingdom formation still has not been pinpointed, few ethnologists suggested that Jaintia Kingdom was established in 1500 A.D. which then gradually undertook the areas of present Sylhet, Sunamgonj, parts of Moulvibazar and Habiganj Districts (Rahman et al, 2018). Jaintiapur, the capital of the Khasi-Jaintia kingdom (1500 AD to 1835 AD) was geographically located inside the Sylhet Division of Bangladesh.…”

PurposeThis study aims at understanding the reasons causing the decline in the practice of traditional, regional architectural methods of creating house forms in the Khasia Punji at Jaflong, Sylhet area.Design/methodology/approachTwo main types of traditional and modern house forms were identified and studied in order to document and analyze the aspects of changes in the construction method and material uses, while the interviews together with observational, qualitative and descriptive study formed an insight into the changing socio-cultural dynamics and evolving lifestyle of the tribe. Apart from physical surveys, the primary data on settlement patterns over twenty years' time were reviewed through satellite imaging while the characteristics of local house forms were also collected from tourist photographs through time recorded in Google database.FindingsThe findings of this research have pointed out that in the case of the Khasi tribe, the shift in temporal context, accompanied by a shift in technological, socio-cultural and economic aspects, is fueling the transformation in the formal expression, material and methods of the house building.Research limitations/implicationsLimitations were posed in setting up more constructive and informative interview sessions with the Khasi people due to the coronavirus disease 2019 (COVID-19) situation which limited the survey outcomes in general.Practical implicationsThe scope of this study is to understand the changes and advances in socio-cultural, technological aspects of a society and their impact on the intricate patterns of life and customs that are evidently reflected in the transformation of built environments.Originality/valueThis research attempts to understand the causes behind the transformation of vernacular house forms, taking place in the Khasi village of Jaflong, Sylhet.
