This study first conducted a questionnaire survey to investigate the users of the lease forestlands of National Taiwan University Experimental Forest in Lugu Township. The survey data was then analyzed by binary logistical regression for determining the factors of intensive use of lease forestland. The results showed that the conducive factors to intensive use of lease forestland were: easier access to forestlands, non-elderly forestland users, having applied for silvicultural subsidy, and higher proportion of forest revenue to household income. In other words, factors able to reduce cost or to increase revenue and to raise the relative income from forestland were important to determine whether or not intensive use of lease forestland. However, various types and origins of lease contracts did not make difference in the intensity of forestland use.
