An exploratory study was conducted in Juri Forest Range-2, a proposed biodiversity conservation area of Bangladeshto explore the present growing stock of tree, regeneration condition and status of non-timber forest products (NTFPs). Thisconservation area contains both natural and artificial plantation was selected by using multistage random sampling method. Fordetermination of plot size and sampling methods, the quadrate size (10 m×10 m) for tree stock measurement, (2 m×2 m) forregeneration survey, (20 m×20 m) for NTFPs survey was determined. Regarding tree stock survey, 14 species under eight familieswere found where Tectona grandis shows average number of stem/ha was 624 and basal area/ha was (10.36 m2/ha) followed byAcacia auriculiformis (0.2 m2/ha and 637 stem/ha), Gmelina arborea (0.2 m2/ha and 600 stem/ha). In regeneration survey, 14species were found belonging to 9 families where Alstonia scholaris shows highest (3,750) seedling per hectare. Regarding NTFPs,bamboo and cane are the most common resources. In last ten years, the total timber output was 1,28,596.14 cubic feet and totalamount of revenue was 4,64,434 US$. The vacant area is 1,335.5 acre which contains 14% of total area. If this vacant area isplanted with suitable species and take proper steps for appropriate management of this species it will be a good biologicallydiversified area.
