“…The latter was also found by Perhans et al [17]. Jonsson et al [24] simulated different silvicultural treatments in southern, middle and northern Sweden, and the opportunity cost of setting aside stands as reserves in middle Sweden was SEK43.424 ha −1 , which is of the same magnitude as the opportunity cost given by Wikberg et al [15] and the results presented here ( Table 4). As the micro topography cost model is independent of the shortest path model, the scenario-based method can easily be adjusted for other wheel-and ground-based extraction systems, e.g., skidders, farm tractors or horses.…”

“…Both the prescriptions and the harvesting cost calculations were on the stand level and, thus, not adapted to retention patches. Jonsson et al [24] did a cost-benefit simulation of how six types of coarse woody debris (CWD) varied with seven management options. One of the management options was retention of small parts of the area, but their focus was the environmental values.…”

Variable retention harvesting is acknowledged as a cost-effective conservation measure, but previous studies have focused on the environmental value and planning cost. In this study, a model is presented for optimizing harvesting cost using a high resolution map generated from airborne laser scanning data. The harvesting cost optimization model is used to calculate the objective value of different scenarios. By comparing the objective values, better estimates of the opportunity cost of woodland key habitats are found. The model can be used by a forest manager when evaluating what silvicultural treatments to implement or as an input for improving the nature reserve selection problem for woodland key habitats or retention patches. The model was tested on four real-world cases, and the results indicate that terrain transportation costs vary more than reported in the literature and that it may be worthwhile to divide the opportunity cost into its direct and indirect components.

“…For instance, for live trees it is most cost-efficient to save birch and aspen in southern Sweden, and pine and spruce in the north (Jonsson et al, 2010). To create dead wood, it is most efficient to set aside forest in northern Sweden, while in southern Sweden it is better to increase the amounts in managed forests (Jonsson et al, 2006). In general, for the creation of dead wood it is more cost-efficient to save naturally dying trees and to create high stumps than to retain living trees, to scarify the soil manually after logging to avoid harm to logs, and to prolong the rotation period .…”

Since the mid-1990s, it has been common practice to leave trees for biodiversity purposes when clear-cutting in Finland, Norway and Sweden, and regulations for such tree retention are today included in national legislation and certification standards. Peer-reviewed research publications on tree retention from studies performed in the three countries were analyzed and about 50 relevant biodiversity studies were found, with the first published in 1994. Most studies were directed towards beetles and dead wood, especially high stumps. General conclusions were that retention trees (1) provide some of the substrate types required by early-successional species, (2) alleviate the most serious consequences of clear-cutting on biota, and (3) cannot maintain characteristics of intact mature forests. Larger volumes and more trees tend to maintain diversity better. There is a particular lack of studies on dispersal, landscape effects and long-term dynamics. There is a need to study further the relationship between the biota and the amount of trees, as well as their spatial arrangement. Retention trees should preferably be evaluated in relation to other components in multiscaled conservation, including woodland key habitats and larger protected areas.

“…Lastly, the experimental application of landscape retention forestry would allow the establishment of operative thresholds that could be used to reach specific conservation goals, according to disturbance regimes and site heterogeneity and composition (Rosenvald & Lõhmus 2008). Combining different measures optimized according to site features and costeffectiveness of interventions, can increase the feasibility of conservation strategies (Jonsson et al 2006). Conservation planning software like MARXAN (Watts et al 2009) offers further instruments to effectively allocate conservation efforts.…”

The forest biodiversity artery: towards forest management for saproxylic conservation

One of the objectives of forest conservation is the set aside of unharvested areas. However, the fragmentation and lack of connectivity of protected areas make the integration of conservation measures in productive forests essential. Strategies to integrate conservation of saproxylic biodiversity in forest management have been developed, but often considering only specific aspects or remaining preliminary otherwise. As the impact of climate change and anthropogenic stresses increases, the development and the synthesis of this approach is crucial. We reviewed the key literature on forest management for biodiversity conservation, integrating forest science perspective to provide a practical management framework. Our goal is to present a management framework that could contribute to the effective preservation of forest insect biodiversity at the landscape scale, without high economic efforts, and addressing the conflicts that still jeopardize sustainable forest management. The results of our review support the creation of micro-reserves inside productive forests, to support large reserves in landscape conservation strategies. Micro-reserves increase the resilience of forest ecosystems to anthropogenic disturbances, through the development of a heterogeneous structure, maximizing microhabitat availability. Modeling forest management and harvest on local natural disturbance would extend the benefits of spatio-temporal heterogeneity in productive forests. Variable retention harvest systems, applied at the landscape scale, are a feasible and adaptable strategy to preserve and increase biodiversity, safeguarding structural legacies such as senescent trees and deadwood inside the productive matrix. The operational shift, from the stand to the forest landscape, is fundamental to extend the benefits of conservation measures. The Forest Biodiversity Artery, composed by several micro-reserves or îlots de senescence, connected by corridors of habitat trees and deadwood, constitutes a network that would deliver old-growth forests attributes to the productive matrix. This planning instrument would support forest connectivity, and socioeconomic constraints.
