The collection and sale of asparagus (Asparagus racemosus) is a major source of income for Praja and Tamang castes around the Royal Chitwan National Park (RCNP) in Nepal. However, the forests where asparagus is harvested are becoming depleted threatening the livelihood of the collectors. To address this issue, at sustainable harvesting practices, this research reports the contingent valuation method (bidding game) and estimates the average willingness to pay (WTP) of collectors under two asparagus collection scenarios. In the first scenario, if forests under the Department of Forests jurisdiction were managed for sustainable harvesting at 1995 rates, the average WTP of collectors was 4.4 NR/kg. In the second scenario, when the forest in the RCNP is managed in such a way that both the current harvesting rate of asparagus is sustained and they are legally allowed to collect asparagus at the present rate, the average WTP of collectors was 8.35 NR/kg. Consequently, there is a good chance of earning revenue for the government and sustaining the livelihood of asparagus dependents by the sustainable management of the Department's and the National Park's forests and giving legal permissions to collect asparagus from the National Park, which would have happened but with financial and legal risks to collectors.
