In scope of biodiversity and sustainable ecosystem development the restoration of the bog ecosystem is important, because by reducing the drainage effect on the bog, the negative impact on adjacent intact or relatively intact raised bogs and other wetland hydrological regimes is lowered. To restore a degraded bog hydrological regime, it is necessary to fill up the drainage ditches and cut out part of the forest stand. While researching scientific literature the author has obtained no evidence that there is a system dynamics model developed in order to simulate the tree cutting intensity in a degraded bog after filling up the drainage ditches with the aim to speed up the restoration of hydrological regimes, thus this approach is an innovative way of restoring the hydrological regime of degraded bogs. In previous studies the author concluded that the STELLA® system dynamics model is an appropriate tool to model the hydrological regime of bog. As a result of this research there is a STELLA® system dynamics model developed which through mathematical relationships helps to better understand the bog water cycle and to determine the consequences of any intervention on the bog ecosystem, primarily the effect of tree cutting. While running this STELLA® system dynamics model by changing the leaf area index, changes in the peat layer moisture level can be observed, which allows to predict the tree cutting intensity in order to reach the desired peat layer moisture level. By changing input data, this STELLA® system dynamics model could be used in other restoration projects of degraded raised bogs.

In scope of biodiversity and sustainable ecosystem development swamps ecosystem restoration is important, because by eradicating the effect of drainage in swamps, negative impact on adjacent intact or relatively intact raised swamps and hydrological regime of other wetlands is lowered. Tree cutting in degraded swamps forest stands would speed up restoration of ecosystems disturbed hydrological regime. Habitat conservation value in long-term is the same as for habitat 7110* Intact raised swamps, as in case of hydrological regime restoration, within time it will transform into 7110*. Several specially protected plant species can be found only in raised swamps. Tree stand transpiration volume varies depending on air temperature and solar radiation. Since in reality it is impossible to change air temperature or solar radiation in order to increase the groundwater level in a swamp, we can reduce the leaf area index (LAI) which is the most significant value influencing transpiration by cutting down trees. Aim of this paper is to examine how LAI interacts with groundwater level by using system dynamics swamps ecosystem model. Swamps ecosystem model shows correlation between LAI and groundwater level. As a result of this research author observes, that LAI interacts groundwater level and system dynamics modelling could be useful to calculate degraded swamps forest stands thinning intensity through mathematical relationships.

The article describes the choice of appropriate network technology that provides sufficient coverage to allow the sensor network to be placed even in the remote and difficult to reach locations and the data to reach the cloud server. Further it describes the components of the sensor network, the operating principle, architecture and the processing of the data obtained to convert them into the input data used in the hydrological simulation model. The NB-IoT sensor network proposed by the authors would not only collect the data needed to operate hydrological simulation models, but, for example, could provide the data needed to forecast weather conditions, particularly if the architecture of this sensor network, because of its low cost, would be widely applied around the globe, joining a unified global sensor network.

The purpose of the study entitled „Exploring documentary heritage for building synergies between research and society” is to study previously unexplored aspects of the documentary heritage, including the part of the legacy that has previously been subject to censorship and has therefore not been studied in depth. When viewing the documentary heritage as historical evidence, it will reveal previously unknown layers and stories of history, thereby directly influencing history and linking national identity to European identity. In order for these layers and stories to reach the public, the people should initially be informed of the existence of such information, which, in turn, could create awareness and to encourage action. This article deals with the existing experience of National Library of Latvia (NLL) and other libraries in en-suring that the new information is brought to the public. Society is complex and differs from country to country, therefore there is no common recipe for libraries for successful dissemination of the new infor-mation. The authors conclude that the most appropriate technique for understanding the local user is to study the user experience, which will become a continuation of this research study.
