FTA, TPP 등 개방시대에 맞서 우리나라 축산업은 경쟁력을 갖춰야한다. 충청북도 진천에 위치한 초원농장(대표 홍경표)은 지난 13년간 축적해 온 노하우를 바탕으로 경쟁력을 확보해 나가고 있다. 특히 초원농장은 지난 12월 16일 개최된 축산농가 행동강령 선포식에서 '신선에너지 우리축산 오리부문 우수농가'로 선정된 만큼 그 경쟁력을 인정받고 있다. 초원농장의 오리성적은 겨울철임에도 불구하고 43일에 3.6~3.7kg 정도로 오리농장 평균성적인 43일에 3.4kg인 것에 비해 매우 우수한 성적을 보여줬다. 초원농장의 농장운영 비결은 무엇일까? 홍경표 대표로부터 오리사육에 있어 가장 중요한 사양관리 요령에 대해 들어보았다.

자연초원(natural grassland)은 연간 강수량이 $250\sim1000mm$, 기온이 $0\sim26^{\circ}C$인 지역에서 형성되는 기후극상의 식생으로써 초본식물, 특히 벼과식물이 우점되어 있다. 이 자연초원은 세계에 널리 분포되어 있는데 지역에 따라 온대초원 열대초원, steppe, prairie, pampa등으로, 식물의 초고에 따라 장초형 초원 단초형초원으로 분류한다. 한국에는 연간 강수량이 많고 연평균기온이 높아서 기후 극상의 자연초원은 성립되지 못하고 식생천이의 도중상으로 소규모의 초본식물군락이 나타난다. 이들은 주로 방치된 경작지나 경작지주변의 인간간섭이 많은곳, 해수나 강물의 영향으로 나무가 생장할 수 없는 곳에 식생천이의 도중상으로 나타나거나, 산림이 산불이나 벌목으로 파괴된 곳에서 제2차천이의 과정으로 초본식물군락이 출현하는데 이것을 야초지(native grassland)라고 한다. 특히 야초지에 가축을 사육할 목적으로 목초를 재배하여 이용할 때는 초지라고 한다. 한국의 야초지식생을 구성하는 주요 우점초종은 억새, 새, 솔새, 잔디, 갈대, 쑥 등이며 건조하고 기온이 높은 여름에는 C-4형 식물이, 수분이 많고 서늘한 봄과 가을에는 C-3형 식물이 높은 생산성을 나타낸다. 야초지는 지표면을 피복하여 바람이나 빗물에 의한 토양침식을 방지할 뿐만아니라 초식동물의 먹이를 생산하고 자연경관을 아름답게 가꾸어 주는 중요한 역활을 하고 있으나 공장부지 주택지 농업용지등으로 개발되어 없어지고 관리가 이루어지지 않아 황폐화 되고 있다. 야초지를 효과적으로 보전하고 이용하기 위해서는 생장이 빠르고 생산성이 높은 우수한 목초를 재배하는 것이 바람직한데 그 방법으로는 겉뿌림초지조성법, 제경법, 시비법이 이용된다.

Based on a long-term ethnographic study, this paper examines how the propositions and practices for desertification management in Inner Mongolia, China have changed over time. Desertification as an ecological issue cannot simply be treated as a something "natural" or "social," while it is an outcome of the construction made by both human and non-human agents. My research has found that the propositions for desertification management have been involved in the process of defining desertification, particularly by selecting different actors related to the ecological process in this region. Ultimately, the crisis in the inner Mongolia has always been constructed by the ways in which the selected actors and their relationships are differently defined. My study also reveals that although the proposed preventive measures, including afforestation, area protection, and pasturing prohibition, have tried to reconcile the conflicts of interest among the different actors, they have always been faced with certain limitations and failed in dryland management. In this historical context of crisis construction, by introducing a new non-human agent, "the chicken," the project of grassland chicken farming has eventually appeared to be an innovative strategy that can overcome the earlier limitations and coordinate the interests of Mongolian pastoralists who have suffered from economic difficulty.

Montane grassland at the summit of Mt. Soback, Korea, was studied to verify the relationships between environmental factors and vegetations on the different slopes. The contents of total nitrogen and excangeable cation and thickness of A-layer of soil in the east slope were greater and thicker than those of the northwest one. Two different community types were observed one, on the east slope, was a grass community and the other, on the northwest, was a grass community. Plant height and annual production of the forb community were taller and greater than those of the grass community. These differences might be correlated with the different of snow depth between two slopes caused by wind in witner. It is clear that the formation of the montane grassland at the study area is mainly caused by fire, wind and topography at the summit.

To develop accurate and predictive global carbon cycle models, it is important to understand the change of accumulated carbon for many ecosystems according to successional stage. In this study, I measured total biomass, litter and soil organic matter contents through an aerial photo and field observation. As a result, accumulated organic matter contents per unit area (kg $m^{-2})$ of three communities composed at grassland were 7.00 kg $m^{-2}$, in Solidago altissima community, 9.18 kg $m^{-2}$, in Imperata cylindrica community, and 12.68 kg $m^{-2}$, in Miscanthus sinensis community, respectively. Accumulated total organic matter contents was high in Miscanthus sinensis community at later succession stage but soil carbon was low. In Miscanthus sinensis community, highly accumulated organic matter contents was resulted from increasing of biomass comparison with that of the other two communities. The pattern of accumulated organic matter contents was changed by changing of the dominant community due to progressing in succession. The accumulated carbon in temperate grassland will be increased with progressing in succession.

The mound grave of Korean traditional funeral culture is a unique habitat which is a Zoysiagrass lawn being sustainable in proper management. We phytosociologically described an unusual Zoysiagrass vegetation with Gueldenstaedtia verna by the Zürich-Montpellier School's method and analyzed eco-floristic characteristics. A new association, Gueldenstaedtio-Zoysietum japonicae ass. nov. hoc loco, was identified and subdivided into festucetosum ovinae, typicum, and trifolietosum repensae. The subassociations were distinguished by the difference in species composition resulting from site accessibility and lawn management method. The association was assigned as not only a regional but also a locally-limited vegetation type, which distributes on a particular microhabitat with strong continentality in the Daegu regional subdistrict of Bioclimatological division. The Zoysiagrass vegetation of Korea was considered as a continental type apparently different from the oceanic type of Zoysion japonicae (Miscanthetea sinensis, Caricetalia nervatae). Mound graves in Korea should be acknowledged as a meaningful habitat for the in-situ conservation of biodiversity and phytocoenosen, despite being a secondary grassland of Gueldenstaedtio-Zoysietum japonicae.
