The Kashmir Himalaya, known for its indigenous and endemic flora, also provides home to a large number of exotic plants, which exhibit a wide taxonomical and distributional stretch. Although, some preliminary studies have been carried out in the region on some aspects of its exotic flora, the inventorization and documentation of its exotic have received a little or negligible attention. There is a lot of scope of these exotic plant species in Kashmir valley, but lack of authentic identification has been as a big hurdle in their scientific management. It is in this backdrop that the present floristic study was carried out to identify, inventorize, document and characterize the exotic plant species grown in the Valley. The present study has revealed that Kashmir Valley grows 317 exotic plant species, which belong to 209 genera in 85 families. Dicotyledons are the largest group, represented by 252 species in 163 genera and 67 families. Monocotyledons comprise 52 species in 37 genera and 13 families. Gymnosperms are the smallest group, with 13 species distributed in 9 genera and 5 families. Asteraceae is the largest family containing 33 exotic species.

This report is an investigation of the revegetation and secondary succession in the burned area of Mt. Sanseung in Taegu region. The forest fire took place in December, 1977. The survey was conducted eight times, -three times from October 1, 1983 to October 3, the same year and five times from August 10, 1984 to August 15, the same year. The floristic compositions in the sampled sites constituted 25 kinds of vascular plants and 21 kinds in the burned area and the unburned area respectively. The biological type in both the burned and unburned areas was H-D1-R5-e type, which is generally common to other areas (Taegu, Kyungpook, Chung Buk and Kangweon areas). In the burned area dominant species were Carex humilisvar. nana, Arundinella hirata and Quercus serrata and on the other hand, in the unburned area Pinus densiflora, Carex humilis var. nana, Rhododendron mucrfonulatum var. ciliatum and Quercus serrata. The species diversity diversity index(H) and eveness index(e) of the burned area were higher than those unburned area. Degree of succession (DS) was 650 in the burned area at the 6th years after the fires and 962 in the unburned area. THe vegetation of the burned area was slowly recovered as of 1984 compared with each other. According to the analysis of the soil preperties, pH, available phosphorus and exchangeable potassium were increased, but organic matter, total nitrogen and total organic carbon were decreased. It is assumed that these results were due to the forest fire.

This study was carried out to investigate the flora of Is. Gageo (Jeollanam-do). The vascular plants were collected 13 times (from June 2008 to September 2011), and 465 taxa in total were identified, including 112 families, 301 genera, 402 species, 3 subspecies, 49 varieties, 9 forms and 2 hybrids. 171 taxa were first records for the region. Among them were seven taxa of Korean endemic plants and the Ministry of Environment-designated plants, which should be protected by the wildlife protection law, were identified as three taxa. There were 54 taxa of the flora with the levels III, IV, V in the floristic indicator plants which was designated by Ministry of Environment. The naturalized plants were identified as 29 taxa, and their naturalization ratio and urban index were found to be 6.2% and 9.0% respectively. There existed many kinds of plants resources having conservational value like $Loxogramme$ $salicifolia$, $Sarcandra$ $glabra$, $Osmanthus$ $insularis$, $Saussurea$ $polylepis$, $Carex$ $ligulata$ var. $austrokoreensis$, $Hosta$ $jonesii$, $Cyrtosia$ $septentrionalis$, etc., in this area. As therefore clear that appropriate plans to conserve the natural habitat of Is. Gageo must be made immediately.
