1. Orsaker till och åtgärder för att förbättra ekonomin i förstagallringar på Åland
Kandidat-uppsats, SLU/School for Forest ManagementSammanfattning : Röjningsbehovet på Åland är stort och andelen eftersatta ungskogar ökar för varje år. Det ekonomiska utfallet i förstagallringar är väldigt dåligt och i många fall obetydlig, vilket gör att intresset för att röja är litet. Det leder många gånger till att ungskogarna röjs för sent och ibland uteblir röjningen helt. LÄS MER
2. Torkstress hos urbana träd i Göteborg: Effekter av låg vattentillgång under torkan 2018
Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : During late spring and most of the summer in the year of 2018 the weather in Sweden was more extreme than normal, with high temperatures and few rainfalls. This resulted in a drought, of which the effects were noticed all over the country. One of the noticeable effects was an earlier leaf abscission from trees. LÄS MER
3. Behaviours of older adults in urban outdoor environments during warm days
Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaperSammanfattning : As a result of climate change, heat waves are expected to increase in frequency, duration, and severity, which is particularly threatening to the urban population. Vulnerable groups, including the older population, are more likely to be affected by adverse health effects due to heat exposure. LÄS MER

5. Can urban tree re-inventories inform future species selection? : diameter at breast height as an indicator for tree performance in Malmö municipality’s tree database
Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)Sammanfattning : Using the inventory database of trees for Malmö municipality, Sweden, this study explored the potential of using the diameter at breast height (DBH) measurement in re-inventories, as a decision-making tool for species selection and management in urban forests. With the escalating pressures of urbanization and unpredictable climate change effects, there is an urgent need for urban forest managers to possess reliable tools that can facilitate the selection of resilient tree species capable of thriving in diverse and changing urban contexts.
