  • The purpose of this study was to investigate the effect on the achievement of knowledge by animation-based learning program(ALP) in environmental education. The topic covered by ALP was "meaning and kinds of alien animals and plants". Four classes were selected and divided into two groups. The one was control group, and the other was treatment. 121 female the eighth graders(60 control and 61 ALP students) were piloted. Whereas control students learned using Powerpoint presentation-based materials, ALP students learned using web-based flash animations and animated database with images and movie clips. The score of knowledge achievement of ALP students was compared to control group students using ANCOVA, and then the score of ALP students was significantly higher than that of control group students(p<0.05). The ALP using animations and animated database was effective on the understanding of the alien animals and plants.

  • Background: Some of the introduced alien species introduced settle, multiply, and spread to become invasive alien species (IAS) that threaten biodiversity. To prevent this, Korea and other countries legally designate and manage alien species that pose a risk to the environment. Moreover, 2160 alien species have been introduced in South Korea, of which 1826 animals and 334 plants are designated. The inflow of IAS can have negative effects such as ecosystem disturbance, habitat destruction, economic damage, and health damage to humans. To prevent damage caused by the inflow of IAS in advance, species that could potentially pose a risk to the environment if introduced in South Korea were designated as alert alien species (AAS). Results: The designation criteria were in accordance with the "Act on the Conservation and Use of Biological Diversity" and the "Regulations on the Ecological Risk Assessment of AAS and IAS" by the National Institute of Ecology. The analysis result of risk and damage cases indicated that mammals affect predation, competition, human economic activity, virus infection, and parasite infection. Birds have been demonstrated to affect predation, competition, human economic activity, and health. It was indicated that plants intrude on the ecosystem by competing with native species with their high-population density and capacity to multiply and cause allergic inducement. Interestingly, 300 species, including 25 mammals, 7 birds, 84 fishes, 28 amphibians, 22 reptiles, 1 insect, 32 spiders, 1 mollusk, 1 arthropod, and 99 plants, are included in the list of AAS. Conclusions: AAS designation plays a role in preventing the reduction of biodiversity by IAS in South Korea and preserving native species. Moreover, it is determined to provide considerable economic benefits by preventing socio-economic losses and ecological damage.

  • Roadside native vegetation provides important habitat for plants and animals, and provides visual amenity and beauty for drivers and rural areas. In particular, native wildflowers create and maintain attractive landscaping and scenic vistas while help protect and restore the natural environment. However, it is lacking in government policies and guidelines about using native wildflowers for roadside vegetation and alien invasive plants are a major threat to our environment. The purpose of this study is to review the regulations and programs for roadside vegetation, especially native wildflowers in USA in order to learn lessons about developing wildflower policies in Korea. A summary of results follows: (1) the goals of roadside vegetation have been shifted from beautification for pleasant driving experience to sustainable and economical maintenance. (2) Various funds and laws by federal and local government are essential for native wildflower planting and roadside enhancement. (3) Ongoing projects on seed collection and seed banking of native plants are conducted by wildflower research centers to conserve and propagate endangered plants. (4) Recognizing that wildflower viewing holds tremendous potential, increasing local governments try to grow wildflower tourism for economic benefits. In conclusion, we should establish a long-range plan and regulations on roadside wildflowers planting in order to create safe and sustainable transportation corridors in Korea. In addition, more research on wildflower habitat and propagation should be warranted and landscape architects should play a definitive role in providing pleasant driving experiences and promoting wildflower tourism.
