Abstract Current federal regulations stipulate that national forests must be managed with due consideration of the value of timber and nontimber outputs. Implementation of nonmarket value information in the forest planning process is hampered by incomplete understanding of the conceptual basisand proper use of those values. This paper presents an overview of (1) the basic economic principles underlying nonmarket valuation theory, and (2) the available estimates of nonmarket values produced by southern forests. The main conclusion of the study is that existing nonmarket value estimatesare reasonable for efficiency analysis at regional and national levels but need to be adjusted to specific conditions for planning at smaller spatial scales, such as the forest, ranger district, or watershed level.

In the past two decades, forest management has undergone major paradigm shifts that are challenging the current forest modelling architecture. New silvicultural systems, guidelines for natural disturbance emulation, a desire to enhance structural complexity, major advances in successional theory, and climate change have all highlighted the limitations of current empirical models in covering this range of conditions. Mechanistic models, which focus on modelling underlying ecological processes rather than specific forest conditions, have the potential to meet these new paradigm shifts in a consistent framework, thereby streamlining the planning process. Here we use the NEBIE (a silvicultural intervention scale that classifies management intensities as natural, extensive, basic, intensive, and elite) plot network, from across Ontario, Canada, to examine the applicability of a mechanistic model, ZELIG-CFS (a version of the ZELIG tree growth model developed by the Canadian Forest Service), to simulate yields and species compositions. As silvicultural intensity increased, overall yield generally increased. Species compositions met the desired outcomes when specific silvicultural treatments were implemented and otherwise generally moved from more shade-intolerant to more shade-tolerant species through time. Our results indicated that a mechanistic model can simulate complex stands across a range of forest types and silvicultural systems while accounting for climate change. Finally, we highlight the need to improve the modelling of regeneration processes in ZELIG-CFS to better represent regeneration dynamics in plantations. While fine-tuning is needed, mechanistic models present an option to incorporate adaptive complexity into modelling forest management outcomes.

This paper describes an approach to forest management decision-making. Acknowledging both objective and subjective elements, the approach offers a methodology to encourage more creative design in forest planning. It uses the descriptive capabilities of simulation modeling in tandem with the prescriptive capabilities of graphical evaluation techniques, to facilitate the use and interpretation of technical forestry information in decision-making problems. It emphasizes a need for an overview of long-term resource behavior as a prerequisite to, and a framework for, forest planning.

Participatory design of management scenarios for the Ticino chestnut belt Current guidelines for forest management ask for multi-functional management schemes, allowing a balance between different forest functions, such as production, protection, recreation and ecology. This requires adoption of multi-criteria processes for forest planning. In such a framework, involving stakeholders from the very beginning of the process might be an additional benefit: it would allow to identify possible broadly accepted forest management strategies, thus facilitating their implementation. In this paper, we present the methodologies and tools we developed between 2013 and 2016, in a process aimed at designing and assessing management scenarios for the chestnut belt forests in the Canton of Ticino (Switzerland). Structured and transparent comparison among the scenarios allowed around twenty representatives of cantonal offices and interest groups to make rational and informed choices, leading to the identification of two low-conflict, compromise management scenarios to be implemented in the near future.

Urban forest planning is necessary to avoid problems coming from the introduction of trees into urban spaces. Within the planning process, how space can be occupied on sidewalks is an important item to indicate which species can be planted according to the canopy characteristics . The objective of this study was to analyze morphometric indexes, to classify the growth pattern and to determine the canopy architecture of ten species planted in the urban forest of the cities Curitiba and Pinhais, Paraná, under conditions of free growth, without competition. The sampled species were characterized by the variables diameter at breast height, total height and canopy height and canopy radius in the north, south, east and west directions, which helped to characterize the morphometry of the species. The canopy architecture was classified according to structural models A 60% of crown ratio. Libidibia ferrea and Koelreuteria paniculata presented the greatest amplitude regarding the canopy form, between vertical elliptic, round and horizontal elliptic. Half of the species were fit in the canopy architecture model of the Koriba type, two in the Troll model and one in each of the D'Attim, Leeuwenberg and Mangenot types.
