Metcalfa pruinosa was considered to be a very harmful invasive species, due to its high species density in nature and wide range of its host plants. M. pruinosa was distributed in 28 sites among 143 sites. M. pruinosa has wide range and diverse host plants of 52 families 110 species including crop, fruits and forest trees. At present, the identified host plant of M. pruinosa are composed of 62 families and 145 species in total since their first appearance was reported. M. pruinosa was found in roadside 46.7%, followed by forests 33.3% and orchard 20%. Nymphs and adults cause damage to crop and orchard by sucking juice, outbreak of fungi through secretion of wax, and reduction of plant assimilation due to the nectar of nymphs. Also, it reduces the merchantable quality of fruits and thus causes economic damage. It is judged that M. pruinosa has been moved along major road via the traffic vehicles.

Background: Cakile edentula (Bigelow) Hook. is a successful invader that has been propagating globally. In Korea, Cakile edentula was found in 2008 for the first time, in the east coast of Korean peninsula. Based on site surveys conducted thereafter, Cakile edentula has propagated in the east coast from Goseong to Jeongdongjin, Gangneung and in the west coast of city of Hwaseong of Gyeonggi-do Province, and Taeangun County of Chungcheongnam-do Province. Results: Cakile edentula has infiltrated into four different vegetation communities (syntaxa) (Calystegio soldanellaeSalsoletum komarovii Ohba, Miyawakiet Tx.1967; Elymo-caricetum Kobomugi Miyawaki 1967; Carex pumila; and Calystegia soldanella) belonging to phytosociological classes of saltwort (barilla) and coastal glehnia. Cakile edentula competes with dominant species such as the saltwort (barilla) and beach morning glory, causing qualitative changes in species composition. It also affects local ecosystems through its competition with indigenous species, causing destruction of the traditional landscape. Conclusions: However, competition of Cakile edentula with indigenous species and the resulting replacement of such species are limitedly reported. Potential competitors with Cakile edentula have not been found yet. In Northeast Asia, qualitative changes realized in local ecosystems due to invasion of Cakile edentula are significantly noticeable. These necessitate proper controls for this invasive alien species to protect and preserve coastal dune areas.

Given the lack of a resistant genetic pool in host plants, the introduction of exotic invasive pathogens can result in epidemics that affect a specific ecosystem and economy. Plant quarantine, which is designed to protect endemic plant resources, is a highly invaluable safeguard that should keep biosecurity with increasing international trade and global transportation. A total of 34 species of plant pathogens including Phytophthora infestans were documented as introduced from other countries into Korea from 1900 to 2010. The genus Phytophthora, classified in oomycetes, includes more than 120 species that are mostly recognized worldwide as highly invasive plant pathogens. After 2000, over 50 new species of Phytophthora were identified internationally as plant pathogens occurring in crops and forest trees. In Korea, Phytophthora is also one of the most serious plant pathogens. To date, 22 species (about one-fifth of known species) of the genus have been identified and reported as plant pathogens in the country. The likelihood of new exotic Phytophthora species being introduced into Korea continues to increase, thus necessitating intensive plant quarantine inspections. As new potential threats to plant health in Korea, six Phytophthora species, namely, P. alni, P. inundata, P. kernoviae, P. pinifolia, P. quercina, and P. ramorum, are discussed in this review with focus on history, disease, biology, management, and plant quarantine issues.

Invasive alien plants were identified and recorded in Ulsan city based on field surveys and related literatures. These plants consisted of 147 taxa in total, belonging to 30 families, 93 genera, 144 species, 2 subspecies and 1 variant. The family of Asteraceae was predominant with 42 taxa, followed by Gramineae with 27 taxa and Leguminosae with 15 taxa. According to the result of life-form based distribution analysis revealed that 62 taxa (42.2%) were annual plants, 48 taxa (33.6%) were perennial plants, 34 taxa (23.1%) were biennial plants, and 3 taxa (2%) were woody perennials. Compare to other administrative districts in Korea, prevalence of invasive alien plants in a certain city of Ulsan showed the seventh highest species number followed after Jeju, Gyeonggi, Jeonnam, Incheon, Seoul and Gangwon. On the basis of the results from the country origin analysis, two dominating taxa were introduced from Europe and America, 55 taxa and 51 taxa respectively. The spreading grade of alien plants was elucidated in order of 1 grade (PS) 67 grade (21.1%)>2 grade (MS) 31 taxa (21.1%)>5 grade (WS) 18 taxa (11.6%)>3 grade (CS) 17 taxa (11.6%)>4 grade (SS) 14 taxa (9.5%). Ulsan city is one of a pivotal conduit for the introduction of invasive alien plants. Thereby, reliable management plans are required to monitor these species.

Pimpinella saxifraga L. (Scarlet pimpernel or Burnet saxifrage), a newly introduced species, was found from Baekyakyi oreum (a parasitic cone or cinder cone) in Seogwipo, Jejudo Island. This species is native to Europe and western Asia and is reported as a widely invasive species around the world. Pimpinella saxifraga is distinguished from other related Korean taxa by leaves that are pinnately compound with 3-7 pairs of segments, which vary from simple, ovate, to 2-pinnatisect, with linear lobes. The vernacular name of "Baek-yak-yi-cham-na-mul" was assigned after the name of the cinder cone where it was initially discovered. We provide descriptions of the morphological characters, photographs and a key to allied taxa in Korea. The geographical origin and introduction routes are unknown, but it is highly likely that it was introduced as fodder given its high nutritious value for sheep and cattle or as a medicinal herb. This species invades commonly grasslands and woodlands and prefers dry, well-drained, and calcareous soils. The distribution of this species was analyzed by searching extensively in surrounding Baekyakyi oreum and adjacent cinder cones, but no other populations were observed. It is protected commonly at the edges or inside of the patchy pine forest in the cinder cone from grazing by cattle; given the worldwide invasive nature of this species, special monitoring and management plans should be developed.

Corythucha marmorata Uhler was newly recorded in Korea as a invasive species at Pohang-si, Gyeongsangbuk-do, Korea in 2011 and at Changwon-si, Gyeongsangnam-do, Korea in 2012. Adults of this species show reticular forewings with a lot of transparent membranes and also show pterigoid process of paranotum with strong processes. This invasive species was originated from North America, and then intruded into Europe and Japan. This species is presumed became an epidemic horticultural pest at present and it is injuring almost of Asteraceae leaves. It was presumed that the invasion of Corythucha marmorata into Korea was prior to September of 2011.

We conducted field surveys of amphibians and reptiles over a two-year period in 16 lagoons along the eastern coastline of South Korea, and determined the habitat characteristics correlated with the number of amphibian and reptilian species and individuals. We documented 11 amphibian species and 8 reptilian species. The dominant amphibian species was the black-spotted pond frog (Rana nigromaculata), and the dominant reptilian species was the red-eared turtle (Trachemys scripta elegans), an invasive species. Among the 14 habitat characteristics, connectivity to mountainous area significantly affected the number of amphibian and reptilian individuals. Other factors, including emerged plant cover, salinity, pH, the number of birds for amphibians and connectivity to agricultural land, lagoon perimeter length for reptiles also influenced the number of species or individuals of them. Our results demonstrate that these lagoons are home to more amphibians and reptiles than has been previously known. To effectively conserve herpetofauna in the lagoon ecosystem, lagoons as well as surrounding wetlands, grasslands, and mountainous areas should be protected.
