| 内容記述 | The objective of this study was to obtain fundamental information on the effective use of goats for management vegetation in camellia garden. An experiment was conducted to determine the influence of grazing 2 goats (average body weight: 41.5 kg) on weeding in camellia garden (Camellia japonica L., planting density: 35 plants / a) consisting of grazing plot (2.0 a) and control plot (1.0 a) from November 17 to 30 (14 days) in 2010 and from May 21 to June 9 (20 days) in 2011, respectively. Sward height and coverage of each plot were measured, thereby the relative summed dominance ratio (SDR_2') was determined. Behaviour of goats was observed and grazing frequency, i.e. the percentage of the number of each plant species to total number of plant species grazed (GF) was calculated for plants with more than 10% SDR_2'. A selectivity index based on Ivlev's electively index (SI) was calculated for each plant species from GF and SDR_2'. The SI can range from -1 to +1, with 0 indicating no selection. In addition, the percentage of injured camellia to total trees was estimated. Solidago altissima L. and Thelypteris acuminata (Houtt.) were dominant in control and grazing plots, respectively in 2010. Solidago altissima L. and Artemisia princeps Pampman. were dominant in control and grazing plots, respectively in 2011. At the end of grazing in each year, the percentage of bare ground was significantly higher in the grazing plot than control (P<0.01), whereas herbage mass was significantly smaller in the former than the latter (P<0.01). On the 2nd day after grazing in 2010, the GF of Thelypteris acuminata (Houtt.) Morton., Microstegium vimineum (Trin.) A. Camus f. vimineum and Miscanthus sinensis Anderss. was more than 10%, however the SI for each plant species was approximately 0, indicating no selection. At the end of the grazing period, the SI for Microstegium vimineum (Trin.) A. Camus f. vimineum was 1.00, suggesting most selective. On the 2nd day after grazing in 2011, the GF of Artemisia princeps Pampman. and Equisetum arvense L. was over 15%, however each SI approximated 0, indicating non-selective grazing. At the end of the grazing period, the SI for the plant was not so high (0.31), indicating less selective, though the GF of Thelypteris acuminata (Houtt.) Morton. was 22.4%. Moreover, it was found that the goats grazed vines. On the other hand, the goats browsed leaves and twigs of some camellias and stripped the bark from the trees by rubbing their horn or head against the trunk. As a result, the percentage of injured camellia to total trees was 4.3% in two years. It was concluded that an injury to some camellias was caused by grazing goats, though weeding by the goats was effective in vegetation management. Therefore, the development of measures to prevent the goats from browsing and stripping the camellia is needed. |
