  • A New Method for Estimating Coarse Root Production in Forest Ecosystem
    • Authors: Van Do T; Sato T, Yamamoto M, et al.
      Pages: 117 - 124
      Abstract: Below-ground net primary production in forest ecosystems includes root exudates and production of fine roots and coarse roots. A new method to estimate coarse root production is described and applied in an evergreen broadleaf forest, Vietnam. Four 1-m3 soil blocks were sampled to collect coarse roots, and measured for diameter (Ø), length (L) and dry mass (M) in 2014. Another new five 0.125-m3 soil blocks were used to measure the coarse root diameter in March 2014 and again in April 2016 to measure the diameter increment. In March 2014, the soil was carefully removed from each 0.125-m3 block using a shovel and trowel. The exposed coarse roots were carefully marked and measured, and the soil was filled in to cover all the roots so they could continue their natural growth. In April 2016, the soil was removed again, and coarse root diameters were measured at the marked points. Five relationships were established between M and Ø2·L for five diameter classes of coarse roots. These five relationships overestimated total biomass by 3.4 percent. Coarse root production at the present study site was 0.99 g m−2 d−1. It is concluded that in suitable soils, the new method to estimate coarse root production using the allometric relationship between M and Ø2·L would be easy and applicable to forest without destructive sampling of standard trees.

  • Cost Plus Net Value Change (C+NVC) Revisited: A Sequential Formulation of
           the Wildfire Economics Model
    • Authors: Rossi D; Kuusela O.
      Pages: 125 - 136
      Abstract: The effectiveness of annual investments in US wildfire management programs has been subject to public criticism. One source of inefficiency may arise from a fragmented budgeting process. In the United States, federal budgets for wildfire management operations are not determined simultaneously by a single decision rule but instead independently by separate criteria. This paper investigates the conditions under which fragmented budgeting will constrain the fire management organization from the attainment of a socially optimal allocation. To accomplish this, we extend the standard model of wildfire economics to account for a sequential decision process inherent to a fragmented budgeting procedure. It is shown that when incident commanders weight the dual objectives of mitigating fire damage and suppression costs evenly, a fragmented budgeting structure does not constrain the fire management organization from reaching a socially optimal allocation. However, with the availability of supplementary suppression funds and the added public pressure to limit wildfire damage, incident commanders may weigh the goal of damage mitigation more heavily than the goal of lowering costs when requesting suppression resources. In this case, incident commanders fail to internalize the full costs of suppression and this creates a circumstance where fragmented budgeting leads to program inefficiency.

  • Branch Elongation and Formation of New Stem Units as Influenced by
           Reductions in Leaf Photosynthetic Capacity
    • Authors: Kidombo S; Dean T.
      Pages: 137 - 142
      Abstract: Leaf area is the primary site for photosynthesis in plants and therefore has a controlling effect on tree growth. Elongation of shoots and formation of stem units on stressed branches were investigated using a series of defoliation and shade treatments. The initial diameter and length of the branch in addition to the modifying effect of treatments on leaf area were used to assess elongation of the terminal bud. Results indicate that elongation of branch terminal shoots was significantly reduced by defoliation or shading of previous years’ foliage. The number of new fascicles in the second year of growth after treatment application was also significantly affected by the loss of previous years’ leaf area. However, shoots of all treated branches elongated and developed a new leaf area, emphasizing the ability of branches to recover from minor effects of defoliation and shade stress. The number of new stem units formed in the terminal bud of the second year was related to the shoot length of the growth cycle.

  • Survival, and Growth Response of Douglas-Fir Trees to Increasing Levels of
           Bole, Root, and Crown Damage
    • Authors: Jones D; Harrington C, Marshall D.
      Pages: 143 - 155
      Abstract: We applied a range of bole and root damage treatments to young Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) trees. Significant natural damage occurred to tree crowns over the course of the 10-year study allowing for an analysis of how damage severity to tree boles, tree roots, and tree tops impacts growth and cumulative survival of trees. Tree bole damage severity, measured by percent bole circumference removed, exponentially reduced cumulative survival across the study period, whereas damage to tree roots had no significant impact on survival. Bole damage had different impacts on survival depending on the relative size of trees that were damaged. At higher levels of bole damage, trees with larger relative diameters had accelerated mortality rates compared with trees with smaller relative diameters. Tree crown height loss averaged at the treatment within stand level reduced the impacts of bole damage on tree cumulative survival response. Increasing bole, root, and tree crown damage severity led to reductions in estimated maximum diameter and height. Bole damage and damage to tree crowns hastened the decline of diameter growth rates and delayed the decline of height growth rates.

    • Authors: Jones D; Harrington C, Marshall D.
      Pages: 156 - 163
      Abstract: Wound closure is an important component of tree recovery from bole damage. Damage to young Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) stands in the precommercial and commercial stages is common, yet few studies have looked at how trees at these stages of stand development respond to common forms of damage. Using data from a 10-year study of artificially damaged Douglas-fir trees, we found reduced potential for relative wound closure with increasing initial tree bole diameter, and increasing initial relative bole area damaged. Wound-closure rates increased for longer periods of time in more vigorous trees, trees on better-quality sites, and trees with intact live crowns. Wound-closure rates were reduced for trees with more relative bole damage, smaller live crown cross-sections, slower relative diameter growth, and more crown competition. Trees with low levels of bole damage relative to lower bole surface area produced more callus tissue than was necessary to cover the original wound, suggesting that long-term tree stability should recover for low levels of bole damage.

  • Focal-Point Aggregation Under Area Restrictions through Spatially
           Constrained Optimal Harvest Scheduling
    • Authors: Yoshimoto A; Asante P.
      Pages: 164 - 177
      Abstract: Existing exact optimization techniques for harvest-scheduling problems with area restrictions are unable to solve explicit spatial issues such as the preservation of old growth forest along with its adjacent units without a priori numeration to generate feasible clusters. This paper builds on a previously developed model, MF-Model I, to frame the problem as a focal-point aggregation problem subject to maximum opening size requirements. We conducted computational experiments to demonstrate how the focal-point aggregation issue of old growth preservation can be solved. Although the computational experiments were limited, the number of focal points and the number of planning periods were shown to have a relatively large impact on computational performance for optimization. Computational performance was found to be more sensitive to minimum preservation size than maximum opening size. Finally, we showed that the proposed approach was able to handle a different explicit spatial issue for avoiding the existence of units smaller than the minimum threshold size along with the maximum opening size requirement for a cluster.

  • Integrating Strategic and Tactical Forest-Management Models within a
           Multicriteria Context
    • Authors: Belavenutti P; Romero C, Diaz-Balteiro L.
      Pages: 178 - 188
      Abstract: Forest-management planning could be addressed at various temporal scales, namely strategic and tactical scales. The former are associated with extended temporal horizons, whereas the latter focus on shorter periods of time and typically encompass further spatial requirements. On the other hand, in most forestry scenarios, the existence of multiple criteria of different nature is the rule rather than the exception. It seems sensible to think that forest-management models would significantly increase their practicality in many cases, if the strategic and tactic models were to be integrated within a multicriteria context. This paper presents an integrated framework for dealing with this type of situation. Thus, two approaches called “top down” and “integrated” have been formulated. To undertake this task, the well-known tool called extended goal programming has been resorted to. The functioning and the strengths of the integrated framework are illustrated with a case study corresponding to fast-growing plantations in Brazil. This framework includes the decisionmaker’s preferences in a more compact model that allows the inclusion of different spatial issues.

  • Comparing the Net Benefit of Forestland Access for Big-Game Hunting across
           Landownership Types in Georgia, USA
    • Authors: Mingie J; Poudyal N, Bowker J, et al.
      Pages: 189 - 200
      Abstract: Big-game hunting is a popular recreation activity on public and private land. No study in the forest economics literature has examined hunting demand by comparing price response and value across different land-ownership classes. By combining travel cost modeling with data collected from a mail survey of licensed big-game hunters, this study estimated and compared the economic value of hunting trips across land ownership types in Georgia, USA. Results indicated that hunting-trip demand was influenced by age, income, retirement status, experience, and the presence of food plots with price response differences across land access types. Hunters on public and nonleased private lands appeared more sensitive to price changes than hunters on leased and personally owned land. The net economic benefit of hunting access varied across access types, with hunting trips to leased and personally owned land yielding more than twice the benefit per trip as nonleased private land or public land. This difference generally increased as travel time costs were factored into the models. Findings will be useful in understanding the net economic benefit of big-game hunting, as well as preferences for and price response to access on hunting lands under different ownership regimes in the Southeast.

  • Risk Attitudes and Conservation Decisions: A Case Study of Family Forest
           Owners in Georgia
    • Authors: Kang M; Siry J, Colson G, et al.
      Pages: 201 - 210
      Abstract: We examine the role of individual risk attitudes in family forest owners’ decisions regarding participation in payments for ecosystem services (PES) programs. We elicited participants’ risk attitudes using the multiple price list methodology and obtained their preferences toward hypothetical PES program designs using a choice experiment contained in a survey instrument. Forest owners required more compensation as the contract length increased and preferred cash payments over tax credits, regardless of their risk attitudes. They also required higher payments for wider stream buffers and for limiting increases in pine plantation area on enrolled parcels. Risk-averse forest owners were more likely to participate in the hypothetical PES programs than risk-neutral and risk-seeking forest owners. Furthermore, risk-averse forest owners required less compensation than risk-tolerant forest owners. Research findings suggest that identifying and targeting risk-averse forest owners in the process of designing and advertising PES programs could increase conservation success with lower budgets.

  • A Technique for Implementing Group Selection Treatments with Multiple
           Objectives Using an Airborne Lidar-Derived Stem Map in a Heuristic
    • Authors: Wing B; Boston K, Ritchie M.
      Pages: 211 - 222
      Abstract: Group-selection silviculture has many beneficial attributes and has increased in application over the past 30 years. One difficulty with group-selection implementation is the designation of group openings within a stand to achieve a variety of complex management goals. This study presents a new method for utilizing geospatial census stem map data derived from airborne lidar in a heuristic environment to generate and select from treatment solutions that best meet management objectives in an efficient manner. The method successfully generated candidate treatment solutions over two entries that met a set of tree size, opening size and spacing constraints. The heuristic was implemented on two separate ponderosa pine stands with similar stand conditions using different group-selection opening sizes. Successful field implementations relied on a tree-marking technique developed in this study that relied on high-precision GPS receivers. The heuristic identified good solutions, but the quality is unknown as this is a large nonlinear optimization problem. Nonetheless, this study provides an innovative, efficient and mathematically defendable alternative for implementing group-selection treatments in stands where accurate geospatially-referenced census can be obtained.

  • Reconciling the Tradeoff between Economic and Ecological Objectives in
           Habitat-Tree Selection: A Comparison between Students, Foresters, and
           Forestry Trainers
    • Authors: Cosyns H; Kraus D, Krumm F, et al.
      Pages: 223 - 234
      Abstract: Habitat trees provide microhabitats for many forest-related species, and thus habitat-tree retention is one of the main measures to integrate nature conservation objectives into forests managed for wood production. By setting aside habitat trees, forest managers have to solve a crucial tradeoff between economic and environmental benefits. Therefore, it is of major importance that trees with desired characteristics are retained as habitat trees. In this study, we analyze habitat-tree selection. Specifically, we are analyzing the outcome of a habitat-tree selection exercise that took place in a so-called “marteloscope” or “tree marking training site” with silviculture trainers, district foresters, and forestry students. Our results show that participants consistently selected habitat trees with a low economic value. However, the habitat values of the selected trees were highly variable. Selection behavior depended on participants’ expertise, with forestry trainers making more consistent decisions and outperforming the students as well as the foresters. Our results show that the selection of optimal habitat trees is not self-evident. We provide some ideas about how it can be improved, benefiting both ecological and economic forest management objectives.

  • Woody Debris and Nutrient Retention following Alternative Biomass
           Harvesting Guidelines
    • Authors: Kabrick J; Goyne K, Stelzer H.
      Pages: 235 - 244
      Abstract: Concern about excessive woody debris removals during biomass harvests has led to the development of biomass harvesting guidelines (BHGs) for retaining woody debris for habitat and nutrient cycling. However, the efficacy of BHGs has not been experimentally examined. Two BHG treatments applied during clearcutting and thinning operations were examined in a replicated complete-block experiment. The first BHG treatment included the retention of one-third of tops of trees ≥8 in. dbh and one-third of trees <8-in. dbh. The second included the retention of all tops of trees ≥8-in. dbh and no restriction on the removal of smaller trees. In clearcuts, the two BHGs each increased the biomass of woody debris retained by 1.7 times compared to where no BHG was applied. However, in thinned units, there were no differences in retained woody debris regardless of BHG application. Nutrient retention trends followed those of biomass. Nutrients retained in woody debris generally exceeded nutrient removals in harvested wood except for calcium, for which removals equaled retention where BHGs were applied and exceeded retention in the absence of BHGs. Findings suggest that applying BHGs for retaining woody debris becomes more important as harvest intensity increases.
