“…Production efficiencies can be enhanced further with the increasing adoption of ‘precision forestry’ techniques, utilising data‐gathering technologies and automation combined with digital networks (Singh et al ., 2021) to aid genetics, planting, silvicultural management and harvesting decisions within plantation forests (Fardusi, Chianucci & Barbati, 2017) and increase productivity. In this way, some areas of industrial plantation forest could be optimised for generating timber yields at a high intensity, following a ‘land‐sparing’ approach which would free up land for other uses such as forest conservation (Betts et al ., 2021).…”

Transitional forestry in New Zealand: re‐evaluating the design and management of forest systems through the lens of forest purpose

Forestry management worldwide has become increasingly effective at obtaining high timber yields from productive forests. In New Zealand, a focus on improving an increasingly successful and largely Pinus radiata plantation forestry model over the last 150 years has resulted in some of the most productive timber forests in the temperate zone. In contrast to this success, the full range of forested landscapes across New Zealand, including native forests, are impacted by an array of pressures from introduced pests, diseases, and a changing climate, presenting a collective risk of losses in biological, social and economic value. As the national government policies incentivise reforestation and afforestation, the social acceptability of some forms of newly planted forests is also being challenged. Here, we review relevant literature in the area of integrated forest landscape management to optimise forests as nature‐based solutions, presenting ‘transitional forestry’ as a model design and management paradigm appropriate to a range of forest types, where forest purpose is placed at the heart of decision making. We use New Zealand as a case study region, describing how this purpose‐led transitional forestry model can benefit a cross section of forest types, from industrialised forest plantations to dedicated conservation forests and a range of multiple‐purpose forests in between. Transitional forestry is an ongoing multi‐decade process of change from current ‘business‐as‐usual’ forest management to future systems of forest management, embedded across a continuum of forest types. This holistic framework incorporates elements to enhance efficiencies of timber production, improve overall forest landscape resilience, and reduce some potential negative environmental impacts of commercial plantation forestry, while allowing the ecosystem functioning of commercial and non‐commercial forests to be maximised, with increased public and biodiversity conservation value. Implementation of transitional forestry addresses tensions that arise between meeting climate mitigation targets and improving biodiversity criteria through afforestation, alongside increasing demand for forest biomass feedstocks to meet the demands of near‐term bioenergy and bioeconomy goals. As ambitious government international targets are set for reforestation and afforestation using both native and exotic species, there is an increasing opportunity to make such transitions via integrated thinking that optimises forest values across a continuum of forest types, while embracing the diversity of ways in which such targets can be reached.

Forest structure is a key element in understanding functionality and resilience of forest ecosystems. Analyses of forest structure have traditionally employed non-spatial measures, due to the simplicity of such approach. However, spatial structure can provide a deeper understanding of tree patterns. However, use of a spatial approach in studying tree diversity is often hampered by the difficulty of implementing theoretical equations and formulas, and the lack of freely distributed tools to calculate such spatial indices. The R package 'treespat' allows to calculate some of the most diffuse stand-level spatial diversity indices. The article describes the basic theory of most diffuse stand-level indices implemented in the package and provide examples on how calculate spatial diversity with example dataset.

“…This task was performed by the survey of routine measurement variables and a few selected indexes of stand structure to create a cost-effective descriptive tool. Index selection was based on relevant literature [4,18,[47][48][49][50] and author expertise in earlier studies focusing on forest stand structure assessment [51,52]. Tree volume and biomass were calculated according to the allometric relationships implemented within the National Forest Inventory [53].…”

“…The experimental design allowed a comparative analysis of 3 silvicultural treatments (customary, innovative, and control) randomly assigned to each of the 9 compartments partitioning each site, with 3 replicates per treatment ( Figure 1). In accordance with earlier studies [49,54], a cluster of 3 circular sampling plots (radius = 20 m) was established within each compartment to survey the measurement variables and a set of stand structure indicators before and immediately after treatment was calculated accordingly ( Table 2). The contagion index and diameter differentiation index were calculated according to the 4 and 3 nearest neighbors to the reference tree, respectively.…”

Aimed at reducing structural homogeneity and symmetrical competition in even-aged forest stands and enhancing stand structure diversity, the present study contributes to the design and implementation of adaptive silvicultural practices with two objectives: (1) preserving high wood production rates under changing environmental conditions and (2) ensuring key ecological services including carbon sequestration and forest health and vitality over extended stand life-spans. Based on a quantitative analysis of selected stand structure indicators, the experimental design was aimed at comparing customary practices of thinning from below over the full standing crop and innovative practices of crown thinning or selective thinning releasing a pre-fixed number of best phenotypes and removing direct crown competitors. Experimental trials were established at four beech forests along a latitudinal gradient in Italy: Cansiglio, Veneto; Vallombrosa, Tuscany; Chiarano, Abruzzo; and Marchesale, Calabria). Empirical results indicate a higher harvesting rate is associated with innovative practices compared with traditional thinning. A multivariate discriminant analysis outlined significant differences in post-treatment stand structure, highlighting the differential role of structural and functional variables across the study sites. These findings clarify the impact of former forest structure in shaping post-treatment stand attributes. Monitoring standing crop variables before and after thinning provides a basic understanding to verify intensity and direction of the applied manipulation, the progress toward the economic and ecological goals, as well as possible failures or need for adjustments within a comprehensive strategy of adaptive forest management.
