Effects of Trichoderma harzianum YC_(459) and soil types on seed germination and seedling growth in rock slope restoration

We carried out experiments with various concentrations of Trichoderma harzianum YC459 in different soil types(forest soil, mixed soil,merchantable soil, and leaf mold soil) to evaluate its effect on seed germination and seedling establishment of four species(Festuca arundinacea Schreb., Dianthus barbatus var. asiaticus Nakai,Lespedeza cyrtobotrya Miq., and Parthenocissus tricuspidata Planch) for rock slope restoration. We also investigated the use of drilled slanted holes on the rock slopes for seedling establishment. The results showed that T. harzianum concentration had significant effects on seed germination, seedling growth, and seedling survival for all the species with different soil types. Seed germination and survival rates peaked at 5% T. harzianum concentration with leaf mold soil and decreased as T. harzianum concentration increased from 5% to 10%. Seedling survival rates of all four species were generally lowest at 0% T. harzianum concentration in all soil types.The height of F. arundinacea and L. cyrtobotrya peaked at 5% T. harzianum concentration whereas that of D. barbatus and P. tricuspidata peaked at 10%T. harzianum concentration. We concluded that 5% T. harzianum concentration with leaf mold soil is appropriate for seed germination and seedling survival rates of most species, thus enhancing seedling establishment. Practical application of the findings of this study will contribute in the vegetation restoration of steep rocks in mountain environments.

Investigation of forest-resources potential of Selenge River Basin on transboundary territory of the Republic of Buryatia and Mongolia

The author studied the issues of the present-day status of forest resources and forest management of the Selenge River Basin on the transboundary territory of the Buryat Republic and Mongolia. It is necessary to establish a good policy for wood cutting of the main and secondary use and reforestation.

Combining Geomatics and Conventional Methods for Monitoring Forest Conditions under Different Governance Arrangements

This study employed an innovative meth- odological framework that combines geomatics and conventional survey methods to monitor changes in forest conditions and examine their associations with local forest governance parameters in a mountain watershed covering 153.3 km2 in the middle moun- tains of Nepal. The study involved two spatial scales and analytical steps. First, geomatics techniques were used to map and detect changes in major land cover types in the watershed between 1976 and 2000 and to analyze relationships between forest cover changes and governance arrangements. This was followed by micro-level analysis of the relationships between the biological conditions of selected forests within the watershed and their governance arrangements, using conventional survey methods and analytical tools. The findings show that forest cover in the watershed in- creased by about 15 per cent during the period. The rate of increase in forest cover was highest in areas under a semi-government type of governance ar- rangement, while the community forests were gener- ally better in terms of current biological conditions compared to the semi-government forests. This in- consistency between the findings from the two analy- ses does not allow us to draw any firm conclusions regarding the role of property rights in determining forest condition, but it indicates that the outcomes of local forest management initiatives may be more de-pendent on local institutional arrangements regulat- ing forest use and maintenance of forest resources than on the type of property rights arrangements. The findings also provide evidence of the methodological suitability of the research approach adopted, which may be useful for addressing many other research questions related to forestry and natural resources management, particularly those involving multiple spatial scales.

Local People＇s Perception of Forest Resources Conservation in Ekiti State, Nigeria

This study examines local people＇s perception of forest resources （FR） conservation around two plantation forest reserves （PFR） and two natural forest reserves （NFR） in Ekiti State in order to determine the factors that can contribute to sustainable FR conservation. Questionnaire and interview were used to collect data from 240 respondents. Data were analyzed using descriptive and inferential statistics. 75.0% and 86.1% of respondents around PFR recognized the importance of conserving the FR for economic benefits and biodiversity respectively, while 66.7% would not want the FR conserved for cultural values. 82.9% of respondents around NFR would want the FR conserved for economic benefits, while 74.3% and 66.7% would not want the forest conserved for cultural values and biodiversity respectively. For efficient conservation, participation in forest management and involvement in decision making with means of 3.45 and 3.52 ranked highest in PFR and NFR respectively. Probit regression analysis showed that in PFR and NFR, age, education and income were positively significant to FR conservation （p 〈 0.05）. Creating an enabling environment that will make local people appreciate historical cultural values of the forest for tourism is essential for efficient FR conservation in the study area.
