Background Medicinal plants are the fundamental unit of traditional medicine system in Nepal. Nepalese people are rich in traditional medicine especially in folk medicine (ethnomedicine), and this system is gaining much attention after 1995. The use of medicinal plants has increased during the COVID-19 pandemic as a private behavior (not under the control of government). A lot of misinterpretations of the use of medicinal plants to treat or prevent COVID-19 have been spreading throughout Nepal which need to be managed proactively. In this context, a research was needed to document medicinal plants used, their priority of use in society, their cultivation status, and the source of information people follow to use them. This study aimed to document the present status of medicinal plant use and make important suggestion to the concerned authorities. Methods This study used a web-based survey to collect primary data related to medicinal plants used during COVID-19. A total of 774 respondents took part in the survey. The study calculated the relative frequencies of citation (RFC) for the recorded medicinal plants. The relationship between plants recorded and different covariates (age, gender education, occupation, living place, and treatment methods) was assessed using Kruskal-Wallis test and Wilcoxon test. The relationship between the information sources people follow and the respondent characteristics was assessed using chi-square test. Results The study found that the use of medicinal plants has increased during COVID-19 and most of the respondents recommended medicinal plants to prevent COVID-19. This study recorded a total of 60 plants belonging to 36 families. The leaves of the plants were the most frequently used. The Zingiber officinale was the most cited species with the frequency of citation 0.398. Most of the people (45.61%) were getting medicinal plants from their home garden. The medicinal plants recorded were significantly associated with the education level, location of home, primary treatment mode, gender, and age class. The information source of plants was significantly associated with the education, gender, method of treatment, occupation, living with family, and location of home during the lockdown caused by COVID-19. Conclusions People were using more medicinal plants during COVID-19 claiming that they can prevent or cure COVID-19. This should be taken seriously by concerned authorities. The authorities should test the validity of these medicinal plants and control the flow of false information spread through research and awareness programs.

Swamp Deer is a globally threatened large-sized deer species confined within small patches of the Indian subcontinent.  Historically, Swamp Deer occurred in Chitwan National Park, Nepal but was extirpated in the 1960s primarily due to widespread hunting.  We assessed the habitat suitability at present for the Swamp Deer in Chitwan National Park using multi-criteria analysis in GIS and vegetation assessment using frequency, dominance, and cover.  Within the 952.63km2 area of the national park, the habitat suitability analysis identified 14.57km2 as highly suitable, 134.87km2 as suitable, and 803.19km2 as moderate to least suitable area.  Most of the national park’s grassland is suitable for Swamp Deer.  Grassland is dominated by Saccharum spp.; Imperata cylindrica is the most widely distributed grass species followed by Saccharum spp., Narenga porphyrocoma, and Apluda mutica.  Grass species of the Poaceae family are the most preferred species by Swamp Deer, which are found within short grasslands.  The study revealed that Padampur Phanta could be the most suitable site for the reintroduction of Swamp Deer due to its highest proportion of short grass and availability of preferred food species and good habitat in comparison to other blocks.  Invasion of swamps of Chitwan by Mikania micrantha and Eichornia crassipes could be a limiting factor for the habitat suitability of Swamp Deer.
