This study was conducted at Jõulumäe, Estonia using GLOBE methods to investigate land cover, forest structure, microclimate, and possible environmental changes compared to observations made back in 2018. The aim was to assess whether paludification processes (peatland formation) are still ongoing in the study area and whether the proportion of managed forest has increased. In addition, the study provided practical experience in applying the scientific method and using field measurement instruments. Fieldwork included observations along a predefined route, during which land cover types, vegetation, and human impact were documented. Tree height, trunk circumference, canopy cover, and forest density were measured using a measuring tape, clinometer, and densiometer in accordance with the GLOBE MUC protocol. Surface and air temperatures were measured at regular intervals to examine the influence of different surface types on microclimate. Observations of soil type, vegetation, and water presence were supported by map data and photographic documentation. The results showed that pine (Pinus sylvestris) remains the dominant tree species and that the ground is still wet, indicating that paludification is ongoing, although peat thickness could not be confirmed due to the lack of soil sampling. No clear evidence was found for an increase in managed forest. Overall, the forest has not changed significantly since 2018 but is now officially protected as a habitat for the western capercaillie (Tetrao urogallus). The study highlights the importance of vegetation, soil, and surface type in shaping local microclimate conditions.
