Trees Outside Forests (TOF) are found in all strata as urban, suburban and rural. Some TOF serve as Tree Related Micro Habitats (TreMs). We conducted the assessment of TreMs on TOF in Kathmandu valley of central Nepal. Inventory was performed in 209 randomly selected points by Excel using circular plots with 20 m radius. Out of 6210 individuals of 150 tree species recorded from the study area, 1038 TOF of 64 species were found to serve as TreMs. 4 forms, 5 groups and 14 types of TreMs were recorded. Habitat types per tree varied from 1 to 6. 1, 2, 3, 4 and 5 habitat types were found in 665 (64.07 %), 293 (28.23 %), 67 (6.45 %), 8 (0.77 %) and 4 (0.38 %) trees respectively. 6 habitat types were found in one Cinnamomum camphora tree (0.10 %) with 8.60 m height and 75 cm DBH. Out of all the forms, groups and types, all were found in Urban TOF, one type (mistletoe) in suburban TOF and one form (fruiting bodies of saproxylic fungi and slime moulds) along with three types (mistletoe, invertebrate nest and sap run) were absent in rural TOF. The study explored the TreMs on TOF in Kathmandu valley. It provides the baseline data useful for micro habitats as well as biodiversity conservation.

Sal is a multipurpose tropical tree that grows as the dominant plant species in Nepal’s lowlands. A comparative study of the Sal population structure was carried out in two blocks of Charpala Community Forest, Rupandehi. A total of 161 species of vascular plants, belonging to 135 genera and 69 families, were recorded, where Fabaceae (26 species) was the dominant family. Densities of Sal trees, saplings, and seedlings per hectare were 4000, 1945, and 742 respectively. A reverse J-shaped curve in the population structure of Block 1 indicated active natural regeneration. However, in Block 2, the lower densities of seedlings and saplings, and the higher densities of intermediate diameter classes indicated insufficient spontaneous regeneration. Average tree biomass and carbon stocks were 522.49 Mg/ha-1 and 245.57 Mg/ha-1, respectively. While Block 2 outperformed Block 1 in terms of tree density, carbon stock, and biomass, Block 1 had the higher density of seedlings and saplings, which improved the regeneration status of that site. Increased demand for lumber for construction has put existing Sal strands in Nepal under pressure. Therefore, a detailed study of its population makeup and natural renewal is crucial.

Ex-situ conservation refers to the conservation of components of biological diversity outside their natural habitats. Since biodiversity is currently being lost at an unprecedented rate in their natural habitats, ex-situ conservation has become a suitable approach in their conservation. Botanical gardens are institutions or places that provide a suitable environment for the survival of threatened plant species. Through living plant collection, the botanical gardens have done tremendous contribution to ex-situ conservation of plant diversity which is in dire need for their conservation. With the establishment of National Botanical Garden (NBG) in Nepal in 1962, ex-situ conservation and protection of wild and threatened plant species has been properly addressed. A total of 547 taxa (542 species), 334 (331 species) of which are exotic and 213 (211 species) of which are native, have been preserved by NBG. NBG harbors 1 extinct in the wild, 1 critically endangered, 6 endangered, 5 vulnerable and 3 near threatened plant species according to the IUCN Red List categories, while 5 are endemic species to Nepal. It has also conserved CITES listed plant species (Appendix I- 1 species, Appendix II- 38 species and Appendix III- 2 species). Therefore, NBG plays a crucial role in the conservation of threatened species, educating the public and supporting them in understanding that conservation is a shared responsibility.

The ethnomedicinal plants used by Pahari community of Shikharpa village of Lalitpur district are documented. The data were collected using a range of participatory tools including the informants from different age group, gender and occupation and inventory method followed by group discussion. A total of 48 medicinal plants (MPs) from 47 genera and 33 families are documented that are used to cure different ailments in human beings and domesticated animals. Among 48 MPs, herbs are the most commonly used followed by shrubs, trees and a parasitic plant.The commonly used part/s to cure the ailments is leaves followed by whole plant, twig, root and fruit, bark, rhizome, seed and tuber and flower. The form of use is external as application on infected part or internally as therapeutic dose. Out of the 48 MPs, 12 MPs are high valued MPs, 17 MPs are moderately valued MPs and remaining 19 are low valued MPs. Based on the informants’ response on curing the diseases, 13 MPs are reported as highly effective, 26 MPs moderately effective and 9 MPs effective. The knowledge about the ethnomedicinal plants in the study area is transferred from generation to generation orally without any documentation till now. Such traditional knowledge needs to be documented before it gets lost and further scientific research on such plants needs to be conducted for drug development in future.

Wood structure of three Nepalese genus Ulmus, Celtis and Trema belonging to the family Ulmaceae are described. Altogether 12 wood samples of these three genus are collected from different localities and studied. The study showed ring porous, semi-ring porous or diffuse porous wood. Transition from early wood to late wood was abrupt in ring porous wood. Early wood pores one to three layered. Late wood pores arrangement in dendritic or ulmiform pattern. Perforation plate is simple and inter-vessel pit alternate. Fiber tracheids, tracheids and libriform fibers were non-perforated tracheal elements while wood parenchymatous cell was apotracheal, marginal and paratracheal. Rays were homo-or heterogeneous. Ulmus differs from Celtis in having ray structure and crystal location. A tentative key is prepared to identify the species based on wood character.

Dendrobium chryseum is an endangered epiphytic and lithophytic orchid species having medicinal and ornamental value. The objective of the present study is to develop micropropagation protocol for D. chryseum. The immature seeds of D. chryseum were used as an explant for the micropropagation. Protocorms were developed within 90 days in Murashige and Skoog (MS) medium without plant growth regulators. Protocorms were differentiated into micro shoots after 30 days of transfer to MS medium supplemented with 2 mg/L Benzyl amino purine (BAP), 1 mg/L kinetin and 10% coconut water. Among eleven different combinations of plant growth regulators (BAP, á-Naphthalene acetic acid (NAA), Adenine sulphate, Kinetin and coconut water) treated for shoot multiplication, maximum number of shoots were obtained in 0.5 mg/L BAP + 0.5 mg/L NAA (5.8 ± 0.53 SE shoots per explant). Longest shoot length was recorded in MS medium with Adenine sulphate (1 mg/L) (2.54 ± 0.03 cm SE). Root induction was carried out by using MS medium with different concentrations (0.5, 1, 1.5, 2.0 mg/L) of Indole butyric acid (IBA) and NAA. The highest numbers of roots and longest root length, both were observed at 2 mg/L IBA (4.63 ± 0.56 SE and 2.09 ± 0.25 cm SE respectively). 2 mg/L NAA showed poor response for root number (0.94 ± 0.21 SE) and root length (0.43 ± 0.07 cm SE). Successful acclimatization of in-vitro grown plantlets was done by wrapping the plantlet with moss kept on fine pine bark and the survival rate of plantlet was about 80% after 30 days. This protocol could be helpful for the effective mass propagation and ex situ conservation of D. chryseum.
金石斛是一种濒危的附生和石生兰花，具有药用和观赏价值。本研究的目的是建立菊花的微繁技术。以金菊未成熟种子为外植体进行微繁。原球茎在不含植物生长调节剂的Murashige和Skoog (MS)培养基中发育90天。原球茎在添加2mg /L苄基氨基嘌呤(BAP)、1mg /L动素和10%椰子水的MS培养基上转移30天后分化为微芽。在11种不同的植物生长调节剂(BAP、á-Naphthalene乙酸(NAA)、硫酸腺嘌呤(Adenine sulfate)、Kinetin和椰子水)组合中，0.5 mg/L BAP + 0.5 mg/L NAA处理的芽数最多(5.8±0.53 SE /外植体)。在含有硫酸腺嘌呤(1 mg/L)的MS培养基中，茎长最长(2.54±0.03 cm SE)。采用不同浓度(0.5、1、1.5、2.0 mg/L)吲哚丁酸(IBA)和NAA的MS培养基诱导生根。2 mg/L IBA处理的根数最多，根长最长(分别为4.63±0.56 SE和2.09±0.25 cm SE)。2 mg/L NAA对根数(0.94±0.21 SE)和根长(0.43±0.07 cm SE)的响应较差。用细松皮上保存的青苔包裹植株，成功地驯化了离体苗，30 d后成活率约为80%。该方案可为金菊的有效大规模繁殖和迁地保护提供依据。
