This study explores the regulatory frameworks and landscape designs of burial grounds in Lithuania, focusing on the legal documents and municipal regulations governing cemetery maintenance and development. Analysis reveals a dichotomy between the Law of Burial of Human Remains and the Law of Greenery, with the former emphasizing burial practices and memorial protection while the latter prioritizes ecological considerations and biodiversity in the green areas. Municipal regulations vary in their approach to tree planting and maintenance, with some prohibiting certain species or arbitrary planting. The absence of specific guidelines for designers and administrators grants them flexibility in shaping burial landscapes, leading to diverse approaches across municipalities. Case studies of recently expanded Nemajūnai, Ginkūnai, Daušiškės, and Ivoniškės graveyards illustrate different approaches to tree preservation and landscape design. The findings suggest a need for greater integration of ecological concerns in cemetery planning and maintenance practices.
