“…In line with these results, Miina et al (2010) found that forest management which promotes bilberry yields is the most profitable in pine stands where the potential bilberry yields are high. The analysis of the inclusion of honey production in Pinus brutia stand management (de Miguel et al 2014) showed that honey-oriented forest management can be much more profitable than sole timber production in stands growing on medium and poor sites. In our case, cone production always improves profitability when cone price is at the current level or higher.…”

Pinus pinea is one of the most important tree species in the Mediterranean region due to the economic value of its edible seeds called ''piñones''. Timber also represents an important source of income from this species. Generally, P. pinea stands have been managed to maximize either timber or seed production, optimization of the joint production of both products being rare. The difficulty in optimizing seed or joint production is the highly stochastic masting habit of P. pinea. The aim of the present study was to find the optimal management of P. pinea stands from the economic point of view when both seed and timber production are considered. A growth and yield model was employed to simulate the dynamics of P. pinea stands of the northern Iberian Peninsula. The novelty of the study is the implementation of a cone yield model that is able to predict expected cone harvests and seed yields when masting is stochastic. The model was linked with an optimization algorithm to obtain optimal schedules for two different stands. The results showed that seed production of P. pinea in the northern plateau of the Iberian Peninsula may increase the soil expectation value by more than 300 % in dense stands and 200 % in sparse stands. When seed yields were considered, rotation lengths were longer and thinnings were delayed. The results were highly sensitive to cone prices and discount rates.

“…Technically, both may be considered heuristic methods although the Nelder and Mead process does employ concepts related to the Simplex Method. de-Miguel et al [47] used the Hooke and Jeeves method to optimise bare land value for Turkish pine (Pinus brutia) stands in Turkey that were capable of producing honey (from bees, using pine pollen) in addition to timber values. Möykkynen and Pukkala [49] also used the Hooke and Jeeves method to optimise bare land value, but for Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) stands that faced root rot problems caused by previous stands.…”

Optimisation in Forest Management

The field of forestry has employed various computer-assisted optimisation approaches since the early 1960s to address the efficient allocation of resources towards various forest management objectives. These approaches continue to evolve, and in the last 5 years, the research has expanded to demonstrate how complex, non-linear relationships can be recognised and incorporated into planning processes at the tree, stand, forest and landscape levels. In addition to an overview of the use of optimisation in forestry, we provide an examination of work published in the last 5 years from 30 international journals, worldwide, which consistently publish forestry and natural resource management research papers. Through this review, we found that landscape-level optimisation is a relatively new and expanding area of research, most often performed by one large public landowner in regions where the resulting plan of action has an effect on all landowners and resources. We also note that at the forest level, exact methods for optimising systems mainly continue to be used, and at the stand level, optimisation seems to now involve exploration of a variety of analytical methods. A large portion of the recent research in the optimisation of forest management have involved European forests, which is a function of large public ownership of land and the tradition and requirements for management planning, and roughly half of the effort has arisen from researchers located in Nordic countries (Denmark, Finland, Norway and Sweden).

“…Furthermore, assessment studies that included multiple ecosystem services have relied mainly on land cover information to quantify ecosystem services provisioning (Bennett et al 2009;Seppelt et al 2011), but it is also important to consider (forest) management when assessing ecosystem services. Finally, several studies have linked model simulations with economics to optimise stand-or forest -level management (Seidl et al 2007;Palahí et al 2009;Miina et al 2010;Başkent et al 2011;Pukkala 2011;Pukkala et al 2011;de-Miguel et al 2014;Pukkala 2014), but there are no studies that linked model simulations with an economic valuation to evaluate impacts of alternative policy options on ecosystem services provided by European forests.…”

Verkerk P.J. (2015). Assessing impacts of intensified biomass removal and biodiversity protection on European forests. Dissertationes Forestales 197. 50 p. http://dx.doi.org/10. 14214/df.197 Forests provide many benefits to society and it is important to understand if, and how, policies affect the provisioning of ecosystem services. The objective of this dissertation was to analyze and evaluate impacts of intensified biomass production and biodiversity protection on ecosystem services provided by European forests.Article I assessed to what extent forests are protected and how felling restrictions affect the potential annual wood supply. Felling restrictions applied to currently protected forest areas reduce the long-term potential supply of wood by 35 million m 3 yr -1 . Despite these restrictions, wood harvesting is allowed to a fair extent in these protected forests.Articles II-V assessed the future woody biomass potentials and impacts of different scenarios on forests using the European Forest Information SCENario model (EFISCEN). In article II, the realisable woody biomass potential was estimated at 741 million m 3 yr -1 in 2010, including woody biomass from stems, residues, stumps and other biomass, ranging from 620 to 891 million m 3 yr -1 in 2030. Mobilising these potentials would imply drastic changes in the management of European forests.According to articles III-V intensified biomass removals could involve trade-offs with other forest ecosystem services. Carbon storage in forest biomass, as well as the amount of deadwood, was projected to decline due to measures to intensify the use of forests. An economic valuation showed that intensifying biomass removals could lead to a net economic benefit measured by the aggregated value of five ecosystem services, as compared to projections without measures to intensify use of forest biomass. Larger social benefits could potentially be obtained if biodiversity protection is enhanced in European forests.The results presented in this dissertation illustrate that careful planning is required to accommodate the need for protection of biodiversity, the expected growing demand for wood, as well as the provisioning of forest ecosystem services. Keywords: ecosystem services, EFISCEN, scenario analysis 4 ACKOWLEDGEMENTSFinally the moment is there that the preface of my dissertation can be written. This means that the work on my dissertation is soon completed, which is a liberating thought! This academic dissertation is the result of work carried out during several years in various projects in which I have been involved as part of my work at the European Forest Institute (EFI). I would like to thank EFI and especially my supervisor Marcus Lindner for providing me the opportunity to work on these projects. I also would like to thank him for all the support he provided throughout the years. It has been a real pleasure to work with him. I also would like to thank all (current and former) colleagues in Joensuu and Barcelona that have made EFI an interesting place to...
