“…Moreover, significant correlations were found among genetic differentiation of western European and northern African populations and annual mean temperature and minimum temperature of the coldest month (Mayol et al, 2015). This confirms the Maxent analysis of yew in the Himalayas, where the minimum temperature of the coldest month determines this species' distribution (Nimasow et al, 2016). However, the Maxent model does not take into consideration local conditions, resulting from micro-relief and local wind systems.…”

Abstract:The knowledge on chorology of species is basic for biogeographic and ecological studies and for conservation actions. The data on the chorology of Taxus baccata in Morocco have not been studied. The bibliographic resources, herbarium material, unpublished data of several botanists and the authors' field notes have been reviewed. Two yew populations on Jbel Lakrâa in the Rif and near Bekrit in the Middle Atlas were measured to verify demographic structure and health conditions. The Maxent model of predicted habitat based on bioclimatic variables was used to evaluate the potential geographic range of T. baccata. The species occurs in the mountain areas of northern Morocco: in the Rif, the Middle and High Atlas, at altitudes between (500) 1200 and 2000 (2350) m. In the High Atlas, it reaches its southernmost locations within the geographic range. The populations represented by the highest number of individuals are found in the Western Rif and Middle Atlas, while from the High Atlas only single, isolated individuals are known. The yew occurred preferably in forests of Cedrus atlantica, Abies maroccana, groves of Betula fontqueri, Ilex aquifolium and Prunus lusitanica and in riparian forests located in narrow gorges. Seedlings were observed only at single localities. The population of T. baccata in the Rif presented a good health condition with successful regeneration, while the population in the Middle Atlas was in a much worse state, where only 4-8 m high yews were observed, without natural regeneration. The Maxent model of predicted habitat, based on bioclimatic variables, suggests that T. baccata could occur today in much broader mountainous areas in Morocco, especially in the Rif and Middle Atlas. However, the progressive decline of this species in Morocco indicates the significant importance of other factors on yew distribution, including microsite conditions and human pressure. Taxus baccata in Morocco is in regression at most of its localities and should be treated as a vulnerable species. Measures to ensure the yew's conservation are needed, especially at its southernmost localities in the High Atlas.

“…The study area is under water scarce, land use system should emphasize on cultivation of low water requirement and high value medicinal plants (Kiran et al, 2009;Pirbalouti et al, 2011;Nimasow et al, 2016). The soil morphological and physiochemical parameters obtained from field as well as laboratory along with climate were evaluated for suitability of Aswagandha, Senna and Tulsi.…”

“…Since the major prime lands of country are occupied with cereals and cash crops, medicinal plants are allocated to marginal and degraded lands which resulted to low productivity. Identification and allocation of suitable land for medicinal plants cultivation is a challenging task for stakeholders (Pirbalouti, 2009, Pirbalouti et al, 2011Nimasow et al, 2016).…”

The present study was carried out to assess the extent of permanent fallow lands and identify the suitability of fallow lands for cultivation of major medicinal plants viz., Aswagandha (Withania somnifera Dunal), Senna (Cassia angustifolia M. Vahl) and Tulsi (Ocimum sanctum Linn) in Nanguneri Block of Tamil Nadu during 2013-14. Indian Remote sensing satellite Resourcesat-2 LISS IV data was used to map the extent and distribution of permanent fallow lands of study area and the detailed soil survey work was carried out to identify the problems and potentials of land resources. The biophysical survey revealed that 41.3% of total geographical area (TGA) in Nanguneri block is identified as permanent fallow lands. Climate and soil resources of fallow lands were evaluated for the medicinal plants suitability for cultivation using the parametric methodology. The results showed that out of 5 identified soils, two soils (N 4 and N 5) are highly suitable for cultivation of all the three medicinal plants. Depth, soil texture and soil pH are identified as a major constraints in other soils. The area analysis revealed that 53.4% of fallow lands in Nanguneri block are highly suitable for Aswagandha and 72.2% of fallow lands as highly suitable for Senna and Tulsi cultivation. These results can be transferred to the local stakeholders for converting unproductive fallow lands into productive hub for medicinal plants.

“…It is a slow growing understory species occurring in forests of Indian Himalayas and grows with Abies pindrow, Quercus semecarpifolia, Q. floribunda, Q. leucotrichophora, Betula utilis, Acer caesium, Pinus wallichiana, Rhododendron arboreum and Betula alnoides (12). In the eastern Himalayas, the species grows in moist temperate zones at an altitude between 1600 to 2700 meters in West Kameng, Tawang, Lohit and Dibang Valley districts of Arunachal Pradesh (13). The plant also grows in hilly regions of Manipur and Meghalaya in north-eastern India (14).…”

Taxus wallichiana Zucc. or the Himalayan Yew is a gymnosperm growing along the Himalayan region of Indian and adjoining countries. The plant is extensively used by local people for treatment of various diseases such as fever, headache, diarrhea, fractures, problems of nervous system etc. It also finds usage in Unani system of medicine. The plant is rich in various bioorganic compounds natural products such as hydrocarbons, terpene alcohols, terpenoids (including taxoids), organic acids etc. The plant has been explored for anti-inflammatory, analgesic, antipyretic, anticonvulsant, immunomodulatory, hepatoprotective and anticancer activity with satisfactory outcome. The pharmacological activity of the plant is largely due to the presence of large number of terpenoids. The bioactive constituents present in the plant interacts with a large number of biochemical pathways involved in inflammatory processes, cell division cycles and inhibits a number of enzymes to bring about its protective action against various diseases. In this review, an attempt have been made to highlight the beneficial properties of Taxus wallichiana in various levels of usage starting from its fundamental ethnobotanical use to pharmacological use involving both in-vitro and in-vivo studies. Insights into the molecular mechanisms of action of the active constituents in bringing about the beneficial activity have also been illustrated. The plant can very well become a source of medicine for better management of a large number of diseases including cancer.
