3,186 rated or chosen profiles from 177 respondents, in up to 6 tasks of 3 profiles varying on 5 attributes.
| Description | Choice experiment: 177 Moldovan residents (city and village) chose in 6 choice sets between the status quo and two alternative plans for the Codru Nature Reserve (territory, plant and insect species conserved, symbolic species observed, visitor price in MDL). |

| Randomization restrictions | yes (stated by the source): fixed blocked design: 6 hand-selected choice sets (2 of 8 candidate sets were dropped as not realistic), identical for all respondents |
| Task order | recorded in the deposit |
| Profile position | recorded in the deposit |
Because the attribute levels were not randomized independently, an estimator has to account for the restriction; a plain difference in means across levels can mislead.
Outcomes:
| choice | Choose between Scenario 0 (current state, no price) and Scenarios 1 and 2 in each choice set (paraphrase of the methodology: respondents can choose the current state with no price, Scenario 0 in all questions) [choice, forced] |
