Seedlings of silkoroi (Albizia procera), chapalish (Artocarpus chaplasha), gam ar (Gmelina arborea), champa (Michelia champaca), and teak (Tectona grandis) were raised in 3 different sizes of polybags to study their growth performances at the nursery as well as in the field for the selection of an optimum size of polybag for large scale propagation. The results showed that the height and diameter growth of these species increased with the increase of polybag size, and maintained a good correlation with the seasonal variations (semi-dry, dry and wet season). In the field, seedlings raised in small and medium sizes of polybags (15 x 10 cm and 23 x 15 cm) showed higher percentage of survivality as their root/shoot ratio was higher. The small size (15 x 10 cm) polybags arc, however, recommended for the propagation of silkoroi, champa and gamar and the medium size (23 x 15 cm) polybags for teak and chapalish.

The outdoor recreation potentials of the Foy’s lake area have been investigated. Participant’s observation and informal pcrsonal/group interview techniques were applied to assess the intensity of visits, monthly income from visitors, monthly expenses for park management, natural and artificial facilities of tourists, outdoor recreation problems and constraints, and the recreation activities participated by the visitors. Picnicking is the highest rccrcaton activity (487c) and walking in the nature is the lowest (5%). The highest number of visitors by occupation, age group, and nature of visits are student (58%), 15-30 years (527c) and friends (327c) respectively. The male-female ratio is 67 : 33. The most serious problems for the visitors is safety and for the management authority is water pollution. The study identifies that the Foy’s lake area has all the components of a recreation park and it identifies some recommendations for development of the lake area to cater the outdoor recreation demand of the dwellers of metropolitan Chittagong.
