The TRIAD approach to forest management involves dividing the forest into 3 zones, each with its own management objectives, but with the overall goal of increasing the ecological and economic sustainability of the forest. For the past 5 years, we have been experimenting with TRIAD zoning in central Quebec, incorporating social interests into the original concept of TRIAD management. Results generally indicate that this approach is economically viable, socially acceptable, and preferable ecologically in this area. Although much remains to be done, thus far the consensus among the various project participants is that this approach may be a good fit for the public forest of Canada.Key words: TRIAD, functional zoning, sustainable forest management, ecosystem management, natural disturbance based management, intensive forestry, mixed plantations, partial cuts, eco-efficiency, conservation, new forestry, green accounting RÉSUMÉDans le cadre d'un aménagement forestier TRIADE, la forêt est divisée en trois zones ayant chacune ses propres objectifs d'aménagement.

“…Through zoning society is able to reduce conflicts between land users via agreed compromises (Werner 1926;Bojorquez-Tapia et al 2004). So far zoning has been used as a spatial tool in urban planning (Conway & Lathrop 2005), tourism, industry and forestry with relative success (Bos 1993). However, the conservation literature lacks examples, methods and applications of spatially explicit, multi-objective and multi-stakeholder zonation schemes.…”

“…Only recently, however, did investigation into systematic zoning begin (Moilanen et al 2005) enabling planning for multi-objective, multistakeholder contexts (Wilson et al 2010). Forest managers used simulated annealing to harmonize site suitability and different forestry regimes (Bos 1993) and Verdiell & Sabatini (2005) Sabatini & Verdiell (2007 internally zoned a protected area designated as a world heritage site in Argentina. Howevers in both cases, the claims of spatially explicit zoning were based only on spatial attributes such as compatibility and connectivity.…”

The design of Biosphere Reserves (BR) poses an interesting problem for systematic planning. It entails a spatially explicitly compromise between economic, social, cultural and biodiversity protection objectives, in a sustainable development context. The global network of Biosphere Reserves includes 563 sites in 110 countries. Currently the spatial configuration of BRs follows a nested scheme, where different land use regimes are assigned to zones in an ad hoc fashion, which complicates the evaluation of their effectiveness. So far in the literature, have not been designed to achieve quantitative objectives, which could limit their value for sustainable development. Using the newly developed version of the software MARXAN © , we solve part of this problem enabling BRs to reach predefined set of spatially explicit quantitative targets, while minimizing the reserves' overall costs (i.e. opportunity, implementation, land value, etc.). Our case study is the Pantanal Biosphere Reserve (PBR), in Brazil. According to our results the PBR could substantially improve its effectiveness if a systematic review of its objectives and goals is performed. Rearrangements of all zones proved to be necessary. Core zones for example, composed of IUCN categories I to IV, increased from its current 1.5% of the BR area to 18.5% to reach all objectives. The absence of quantitative guidelines from UNESCO for the configuration of BRs has limited their effectiveness. Our quantitative systematic approach provided the first insights into potential requirements for zone partitioning, prescribing 22 ± 5% to be allocated in core zones, 22 ± 3% in buffer zones, and 33 ± 4% in transition zones. The most useful outcome, however, was the flexibility the software offered to reach multiple objectives simultaneously.

“…Heuristics should be adopted since exact enumeration methods cannot be used to solve such hard combinatorial optimization problems. A common heuristic for solving these zoning problems is based on the well-known simulated annealing (SA) paradigm (Bos 1993, Verdiell et al 2005. For example, Verdiell et al (2005) propose an SA method for creating a protected natural area for ecological purposes.…”

Coupling urban cellular automata with ant colony optimization for zoning protected natural areas under a changing landscape

Optimal zoning of protected natural areas is important for conserving ecosystems. It is an NP-hard problem which is difficult to solve by using common geographic information system (GIS) functions. Another problem is that existing optimization methods ignore potential land-use dynamics in formulating optimal patterns. This article has developed a new method for solving complicated zoning problems by using ant colony optimization (ACO) techniques. Significant modifications have been made, so that traditional ACO can be extended to the solution of area optimization problems. Two strategies, the singleyear coupling strategy and the merging-year coupling strategy, have been proposed to couple urban cellular automata with ACO for zoning protected natural areas under a changing landscape. This proposed method has been tested in the metropolitan region of Guangzhou, China, by using Geographical Simulation and Optimization System (GeoSOS) software. The experiments indicate that the modified ACO can effectively solve this optimization problem without getting stuck in local optima. This method has better performances compared to other traditional methods, such as simulated annealing (SA), iterative relaxation (IR), and density slicing (DS). The use of the best coupling strategy can improve the accumulative utility value of the zoning by 4.3%. Moreover, it is also found that the adoption of the best protection pattern could significantly promote the compactness of future urban forms in the study area.
