Abstract
The study was conducted in Thakurgaon sadar upazila of Thakurgaon district. Five villages
namely Paharbhanga, Bhelajan, Palli-Bidyut Bazar, Jamalpur and Akhanagar were
selected. Among randomly selected 60 homesteads, tree diversity per homestead ranged
from 0 to 2.37 using Shannon Wiener index. Twenty-one (21) different tree species under
15 families were identified, among them Betel nut (Areca catechu) was the most
dominating species and the least dominating species was Tetul (Tamarindus indica).
Among small, medium and large home garden categories, the highest mean tree density ha
1
(355.76) was observed from large home garden which showed the maximum mean basal
area (161.82 m
2
ha
-1
), mean tree carbon (100.61 Mg ha
-1
), SOC (28.02 Mg ha
) and tree C
+ soil C stock (181.13 Mg ha
-1
) compared to medium and small homesteads. Among the
selected areas, the large farmers had the highest daily income from homesteads (Tk. 79.37)
followed by medium and small homesteads. Therefore, the results of the study confirmed
that the selected areas can serve as a valuable ecological means in terms of carbon stock.
