Solar photovoltaic (PV) panels can be installed on degraded land to avoid competition for land resources with agriculture or conservation. However, there is a paucity of research addressing the question of which management practices, if any, might enhance vegetation distribution in cutaway peatlands during the conversion to PV farms. Further research is necessary to combat the decline of biodiversity and promote sustainable land use. In this thesis, the following research questions were answered: What are the biogeochemical conditions (peat characteristics, air temperature (Ta), and current vegetation) at two cutaway sites where operation has ended three and ten years ago? Do these conditions differ between them and is there a relationship between the variables? Additionally, the study examined whether the Ta varied under the PV panel imitating frame and in open field conditions. Soil samples (n = 40, 20 at each site) were collected and the plant community was recorded in the field. The Ta was recorded under the panel imitating frame and in the open field. Aerial photographs of the study plots were created with a drone. The prevailing conditions and plant community were then visualized with descriptive statistics, correlation analysis and ordinated with non-metric multidimensional scaling (NMDS). The data analysis revealed that the biogeochemical conditions of the sites were mostly similar. However, the older site exhibited a greater diversity of vegetation than the newer site. A strong positive correlation was identified between Ca and Mg content. Additionally, the daily average Ta was observed to be higher in the open field than under the frame. A management plan was developed, based on these study results, for the cutaway sites to facilitate the peatland vegetation succession. The proposed management methods, tree felling, ditch blocking, and remodeling of the soil profile were suggested to promote the water accumulation. The rehabilitation measures should be aimed towards oligo-mesotrophic fen type plant communities. The study findings and the proposed recommendations provide a framework for considering biodiversity in PV projects situated within cutaway sites.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2025-03-03T08:04:55Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2025-03-03T08:04:55Z (GMT).
