We received the responses of almost 25 % of the experts to whom the questionnaire was sent. We sent the questionnaire to environmental experts from all local municipalities in Estonia, also to specialists from Environmental Board and Environmental Ministry, Land Board and State Forest Management Centre, Environmental NGOs, companies in the fields of environmental research and consulting, and land resource excavation, other governmental agencies, and scientists working with the topics in the project.

About half of the respondents had theoretical knowledge and practical background in the field of land resource excavation and quarry reclamation and over quarter of respondents had theoretical knowledge, so we can consider the respondents to be true experts in the field. The answers to questions were very profound and explained the thoughts of the respondents comprehensively, which we will analyse during the next few weeks. This gives us good basis for the project and further development of the decision-making model.
