Most studies valuation that have been described previously including forest ecosystems do not see the forest ecosystem services as natual capital / natural assets and even the socio-ecological context. The implication is that forest ecosystem services are considered as an economic asset / economic capital. the concept of value used in the valuation is the concept of the value of output. Though the forest ecosystem services has the characteristics of a sustainable dynamic and as part of the life supporting system including the ability resilience and self-terrific capacity. So that the forest ecosystem is no longer seen as economic assets, but with the characteristics of the dynamic and sustainable forest ecosystem is seen as natural or natural capital assets. The current perspective marginalize other forest ecosystem functions, such as socio-economic functions. Whereas the concept of an insurance value of forest ecosystems is not just the case as seen from the perspective as natural capital, but the role of social values in maintaining the sustainability of forest ecosystems is crucial, as reflected by the presence of heritage value, and existence value. So that the insurance value of the forest ecosystem occurs because the forest ecosystem serves as a natural asset / natural and social capital assets / social capital.

Forest Ecosystem Services

Abstract Forest ecosystems represent the most important values of natural assets. In economic valuation techniques, to estimate the value of forest ecosystem services, the attention is still focused mainly on their market values, i.e. the value of benefits measured in the economic calculation based, first of all, on the price of timber. The valuation of natural resources is currently supported by considerations of the global policy, in order to strengthen the argumentation justifying the need to incur expenditure related to the protection of biodiversity. There is increasing evidence that biodiversity contributes to forest ecosystem functioning and the provision of ecosystem services. Natural capital of forests can be consumed directly as food, wood and other raw materials or indirectly – by benefitting from purified water and air, safeguarded soils or protected climate. At the same time, forest ecosystems provide us with a range of intangible values – scientific, cultural, religious as well as encompass heritage to pass on to future generations. In the era of increasing pressure on the use of free public goods (natural resources), it is necessary to improve understanding of the role of forests in creating national natural capital, and in enhancing the quality of human life. All things considered, the so called non-market forest ecosystem services may have a much higher value than the profits from the production of timber and raw materials. Needless to say, non-market values of forest ecosystems are of great importance for the quality of human life, and the awareness of this should translate into social behavior in the use of natural resources. This paper reviews the methods to estimate the value of forest ecosystem services in view of recently acknowledged paradigm to move forward from economic production to sustainable human well-being.

Forest Ecosystem Services

Forest and climate change in the inner-Alpine dry region of Visp Over the past decades, observed increases in temperature have been particularly pronounced in mountain regions. If this trend should continue in the 21st Century, frequency and intensity of droughts will increase, and will pose major challenges for forest management. Under current conditions drought-related tree mortality is already an important factor of forest ecosystems in dry inner-Alpine valleys. Here we assess the sensitivity of forest ecosystems to climate change and evaluate alternative forest management strategies in the Visp region. We integrate data from forest monitoring plots, field experiments and dynamic forests models to evaluate how the forest ecosystem services timber production, protection against natural hazards, carbon storage and biodiver-sity will be impacted. Our results suggest that at dry low elevation sites the drought tolerance of native tree species will be exceeded so that in the longer term a transition to more drought-adapted species should be considered. At medium elevations, drought and insect disturbances as by bark beetles are projected to be important for forest development, while at high elevations forests are projected to expand and grow better. All of the ecosystem services that we considered are projected to be impacted by changing forest conditions, with the specific impacts often being elevation-dependent. In the medium term, forest management that aims to increase the resilience of forests to drought can help maintain forest ecosystem services temporarily. However, our results suggest that relatively rigid management interventions are required to achieve significant effects. By using a combination of environmental monitoring, field experiments and modeling, we are able to gain insight into how forest ecosystem, and the services they provide, will respond to future changes.

Forest ecosystems are important providers of ecosystem functions and services belonging to four categories: supporting, provisioning, regulating, and cultural ecosystem services. Forest management, generally focused on timber production, has consequences on the ability of the system to keep providing services. Silviculture, in fact, may affect ecological structures and processes from which services arise. In particular, the removal of biomass causes a radical change in the stocks and flows of energy characterizing the system. Aiming at the assessment of differences in stored natural capital and ecosystem functions and services provision, three differently managed temperate forests of common beech (Fagus sylvatica) were considered: (1) a forest in semi-natural condition, (2) a forest carefully managed to get timber in a sustainable way and (3) a forest exploited without management. Natural capital and ecosystem functions and services are here accounted in biophysical terms. Specifically, all the resources used up to create the biomass (stock) and maintain the production (flow) of the different components of the forest system were calculated. Both stored emergy and empower decrease at increasing human pressure on the forest, resulting in a loss of natural capital and a diminished ability of the natural system to contribute to human well-being in terms of ecosystem services provision.

The World

The technical framework of China’s Forest Ecosystem Inventory System (CFEIS) was recently developed based on ecological indicators assessed continuously in the field at forest ecosystem research stations and China’s Forest Resource Inventory (CNFRI) conducted every 5 years. The CFEIS consists of Field Observations (FOs)of ecological indicators and Distributed Valuations (DVs)of forest ecosystem services. The CFEIS can be used with the CNFRI to observe and monitor the ecological status of forests in China. This paper provides a brief review of the CFEIS by introducing its establishment and summarizing its application coupled with the CNFRI. For the FOs, the principles of the monitoring system layout are provided. The Chinese Forest Ecosystem Research Network (CFERN) was set up, which was the largest nationwide network of forest ecological stations in the world. The facilities and equipment were systematically assembled. The national forestry standards were drawn up for describing and measuring the ecological indicators of forest ecosystems, and these standards were used to specify data collection and transmission. For DVs, a distributed measurement method was created, and an indicator system of evaluation was studied and established, with the CNFRI integrated; a series of evaluation formulas and a package of models were also integrated with the DVs. The CFEIS integrated with the CNFRI estimates forest ecosystem services in China and the ecological benefits derived from the Grain for Green program, and a green national economic accounting system will provide an important case for monitoring and inventorying forest ecosystems at a national scale. The CFEIS can provide important experiences for forest ecosystem inventory systems in China and many other parts of the world.

Decision Making Processes

The use and evaluation of riparian forest ecosystem services is a topical issue in Latvia involving interests of different target groups. Research work on proper management methods, their impact on biological values and production function has been started in 2014, while information on social values was missing. Particular methodology was designed and three different approaches of opinion polls were used to obtain information on use of riparian forest services and their evaluation by public in spring, 2015. In total there were 1024 questionnaires distributed out of which 418 were analysed for the research purposes along with 224 filled on the Internet. Different services of riparian forest ecosystems were used by 88 % of respondents, mostly walking along rivers and swimming were mentioned. Respondents evaluated three different scenarios of forest management and 96% of them gave preference to the scenario which required implementation of sustainability criteria resulted in high diversity of species and an increase of esthetical values. Large part (61 %) of respondents accepted the idea of voluntary work to improve the condition of rivers and riparian forests and in average there were ready to work 3.8 days per year. Willingness to pay (WTP) to improve the situation of riparian forests and rivers close to a residence place of a respondents was expressed by 62 % of respondents, in the average 28.50 Euro per year was mentioned. The current research is a starting point for evaluation of riparian forest ecosystems and provides valuable information for further analyses. Research data are used to identify factors influencing the use and evaluation of different services provided by riparian forest ecosystem. Results will be used in decision making processes related to legislation and management changes, as well as in valuation of ecosystem services and planning of public use of riparian forests.

Forests play an important role in biodiversity conservation, being one of the main providers of ecosystem services, according to the Economics of Ecosystems and Biodiversity. The functions and ecosystem services provided by forests are various concerning the natural capital and the socio-economic systems. Past decades of remote-sensing advances make it possible to address a large set of variables, including both biophysical parameters and ecological indicators, that characterize forest ecosystems and their capacity to supply services. This research aims to identify and implement existing methods that can be used for evaluating ecosystem services by employing airborne and terrestrial stationary laser scanning on plots from the Southern Carpathian mountains. Moreover, this paper discusses the adaptation of field-based approaches for evaluating ecological indicators to automated processing techniques based on airborne and terrestrial stationary laser scanning (ALS and TLS). Forest ecosystem functions, such as provisioning, regulation, and support, and the overall forest condition were assessed through the measurement and analysis of stand-based biomass characteristics (e.g., trees’ heights, wood volume), horizontal structure indices (e.g., canopy cover), and recruitment-mortality processes as well as overall health status assessment (e.g., dead trees identification, deadwood volume). The paper, through the implementation of the above-mentioned analyses, facilitates the development of a complex multi-source monitoring approach as a potential solution for assessing ecosystem services provided by the forest, as well as a basis for further monetization approaches.
