Tulipa(Liliaceae) is a well-known ornamental plant that supports a horticultural trade worth over a billion euros. Existing research highlights the expanding array of risks faced by Tulipaspecies, with climate change emerging as a significant and escalating threat. However, the fate of phytogeographically restricted red-flowering species of tulips in the Pamir-Alay mountain system is crucial, as they are also harvested by local people or visitors purely for their ornamental attractiveness. To study this, 41 bioclimatic and ecologic variables were utilized in the investigation. The suitable areas for T. ingensare expected to increase nearly twofold, while for T. affinisand T. carinata, they will remain constant. However, suitable habitats for T. tubergenianaare projected to decrease considerably. Surprisingly, the western Tian-Shan, where these species are not native, was highlighted as climatically suitable and may be an important area for translocation efforts in the future for T. affinis, T. carinata, and T. ingens. We also identified protected areas that could provide suitable habitats for these species. Additionally, we recommend creating living collections of T. tubergeniana, given the significant decrease in suitable habitat. Ultimately, relocating these species to protected regions with projected suitable habitats plays a crucial role in supporting their survival.

Magnolia ventii, a critically endangered plant, is endemic to Yunnan province in China and categorized as EN Blab(iii); D on The IUCN Red List of Magnoliaceae; it is also a plant species with extremely small populations. Data was first collected from a literature review consulting related specimen and analysis to a number of collected data. During the process of actual field investigation (Oct.-Nov., 2011 and Mar., 2013) field measuring method was primarily adopted, combined with the typical sampling method and participatory rural appraisal (mainly adopted method in Ethnobotany). The results show that the total number of individuals observed amounted to 580-630 (including 190-200 big adult trees, 100-120 adult trees, 200-210 saplings and 90-100 young trees), of which there were 300-320 in Jinping county, 140-160 in Hekou county and 140-150 in Pingbian county, while less than a quarter of the total were found distributed in protected areas. Given the rarity of this species in its natural habitat, we propose several potential conservation strategies to the species. [ABSTRACT FROM AUTHOR]
