Wetlands have been fundamental for survival of both animals and humans and are known to be beneficial för biodiversity. Furthermore, they are also very important as functional systems in nature. Wetlands can tribute to hold water in the ground and will dampen high water at floods. Because of ditching in favor of agriculture the last centuries, wetlands have become more and more rare, globally almost 50% has disappeared and in Sweden, up to around 90 % in some areas. Wetlands produce what we call ecosystem services (EST), which are services provided by nature that humans are in need of. An example of this can be production of food such as fish. This study explore what kind of EST two specific areas possibly can produce in both wetlands and non-wetlands scenarios. The purpose of this study, beside identifying EST, was to highlight and illustrate the investment benefits of building constructed wetland on earlier ditched land. An evaluation of EST was therefore the primary purpose of this study. Data concerning the two selected areas were collected, and with the help of Naturvårdsverket’s “Guidance of ecosystem services” (2017) an identification of several EST were made. Based on the data collected, solely qualitative evaluation was made. The result showed that constructed wetlands generate more EST than non-wetlands does and that wetlands is higher valued regarding EST related to biodiversity and cultural value. Furthermore, neither object wetland nor non-wetland, received a high score in the evaluation of greenhouse emission within a 100-year perspective. Additionally, it showed that to be able to evaluate investment benefits, more studies are needed.
