In my referative bachelor's thesis I studied the natural conservation techniques which everyone can use and how to grow native species in home gardens. During my master's studies I mainly focused on biodiversity and everyone's nature conservation concept. The purpose of my master's thesis was to map and study the condition of biodiversity in the parks in Tartu. In addition, I tried to give some reccommendations and guidelines to enhance the biodiversity in the city. My supervisor was Aveliina Helm.
