The critical level of hidden bias is reported in Table 3. The critical
level of bias ranges from 1.05–1.10 to a maximum of 1.45–1.50. The
value of 1.50 indicates that participants and non-participants differ in
their odds of participation up to 50%. The numbers of treated and number
of control are also reported in the Table 3. The results are in linewith
previous studies such as (Ali and Abdulai, 2010; Ali and Olaf, 2013).
In Bhutan Community Forestry Programhas been in place for several
years and the result from ATT (Appendix 1) shows there are some differences
among the old and new members in terms of benefits i.e. longer
the duration of participation more are the benefits and vice versa
