Simple Summary: In this study, we investigated the environmental characteristics of all known habitats of Epilobium hirsutum in Korea. Habitat characteristics are influenced by various environmental factors such as water, soil, and temperature. In this investigation, we analyzed the environmental factors influencing the population size of this species, which is classified as endangered in Korea. Our findings indicated that atmospheric and soil conditions had the greatest impact on the population size of E. hirsutum. These results serve as a valuable reference for developing management strategies for E. hirsutum habitats and provide foundational data for future habitat restoration and improvement efforts. Epilobium hirsutum has been identified as a Class II endangered species in Korea. Therefore, there is an urgent need to develop habitat conservation and improvement strategies for the protection of E. hirsutum. In this study, we aimed to evaluate the environmental characteristics of E. hirsutum habitats and identify key environmental factors influencing the population size. To this end, we conducted field surveys and performed a spatial data analysis to collect data on 38 environmental characteristics associated with the population size of E. hirsutum. We performed factor and path analyses to identify the environmental factors influencing the population size and the correlations between the population size and environmental factors. The common factors identified in both analyses were the average temperature in March, available P, soil pH, and soil humidity. Therefore, to manage E. hirsutum habitats or create alternative habitats, areas with a low air temperature and high soil moisture must be selected. It is necessary to remove tall plants and amend soils with alkaline fertilizers containing P. Additionally, it may be effective to implement a management strategy that induces vegetative propagation and seed germination by replacing agricultural waterways made of concrete with those made of rock and soil. [ABSTRACT FROM AUTHOR]

The complete chloroplast (cp) genome sequence of Myuroclada maximowiczii (GenBank accession number MT726030), a species of moss in the Brachytheciaceae family, was determined using Illumina HiSeq paired-end sequencing data. The total size of the cp genome was 124,607 bp. The genome contained a large single-copy (LSC) region of 86,684 bp, a small single-copy (SSC) region of 18,483 bp, and a pair of identical inverted repeat regions (IRs) of 9,720 bp. The genome contained 82 protein-coding genes, 36 transfer RNA (tRNA) genes, and eight ribosomal RNA (rRNA) genes. The cp genome presented here will provide useful information for future phylogenetic and evolutionary studies of Myuroclada species., Competing Interests: There are no conflicts of interest for all the authors including the implementation of research experiments and writing this article., (© 2020 The Author(s).
