Abstract

We identify policies that would provide a solid foundation in key international negotiations to ensure that primary forests persist into the 21st Century. A novel compilation of primary forest cover and other data revealed that protection of primary forests is a matter of global concern being equally distributed between developed and developing countries. Almost all (98%) of primary forest is found within 25 countries with around half in five developed ones (USA, Canada, Russia, Australia, and NZ). Only ~22% of primary forest is found in IUCN Protected Areas Categories I-VI, which is approximately 5% of prea-griculture natural forest cover. Rates of deforestation and forest degradation are rapid and extensive, and the long-term integrity of primary forest cannot be assumed. We recommend four new actions that could be included in climate change, biodiversity, and sustainable development negotiations: (1) recognize primary forests as a matter of global concern within international negotiations; (2) incorporate primary forests into environmental accounting; (3) prioritize the principle of avoided loss; and (4) universally accept the important role of indigenous and community conserved areas. In the absence of specific policies for primary forest protection, their unique biodiversity values and ecosystem services will continue to erode.

Introduction

Despite the international attention paid to deforestation, forest degradation, and improving forest management, primary forests continue to decline rapidly due to ongoing land-use encroachment (OECD 2006; Karp & Richter 2011), and their future cannot be assumed (Laporte et al. 2007). Primary forests are globally irreplaceable with unique qualities that make significant contributions to biodiversity conservation, climate change mitigation, and

sustainable livelihoods (Foley et al. 2007). Off the international community's policy agenda, however, is how to maintain the integrity of the world's remaining primary forests. Deficiencies in international forest policy can be rectified over coming years but the window of opportunity provided in relevant negotiating forums is shortlived.

Here, we identify four new actions that would provide a solid policy foundation for key international negotiations, including forest-related multilateral environmental

agreements, to help ensure that primary forests persist into the 21st Century: (1) recognize primary forests as a matter of global concern within international negotiations; (2) incorporate primary forests into environmental accounting; (3) prioritize the principle of avoided loss; and (4) universally accept the important role of indigenous and community conserved areas. We first provide an update on the current distribution and condition of the world's primary forest.

Forest distribution and condition

Along a human-use continuum, three categories are recognized: (i) primary forests—naturally regenerated forest of native species, where there are no clearly visible indications of human activities and ecological processes are not significantly disrupted; (ii) forests used for industrial logging and where there are clearly visible signs of human activities but where forests are reliant on natural regeneration processes ("production forests"); and (iii) planted forests predominantly composed of trees established through planting and/or deliberate seeding of commercial varieties ("plantation forests") (FAO 2010). The Collaborative Partnership on Forests, an informal, voluntary arrangement among 14 international organizations and secretariats with substantial programs on forests that supports the work of the U.N. Forest Forum, also uses these three categories of forests. Primary forest therefore can be defined as natural forest largely undisturbed by industrial-scale land use. "Intactness" is a measure of the degree a natural forest landscape has been degraded and fragmented by human land use (additional material on the definition of primary forest and intact forest landscapes is provided in Supporting Information). Of the world's extant 40.1 x 106 km2 of forest, some 57% is subject to industrial logging or designated for multiple uses including wood production, 7% is plantation, and around 36% (14.5 x 106 km2) is primary forest (FAO 2010).

We completed a novel global compilation of primary forest cover, building on the global survey of Potapov etal. (2008) (see Supporting Information for details of materials and methods). The results and associated world map revealed that of the —13.1 x 106 km2 of intact forest landscape (i.e., primary forest in contiguous blocks >500 km2), 50% occurs in snow/polar regions; 46% in equatorial areas; and 3% in warm temperate climatic zones (Figure 1 and Table S1). Our calculations also suggest there is between 1.4-3.5 x 106 km2 of primary forest in blocks <500 km2 worldwide. These smaller areas of primary forest assume particular conservation significance in otherwise extensively cleared and fragmented bioregions as refuges, core zones, reference ar-

eas and sources of propagules for landscape restoration. Almost all (98%) primary forest occurs in 25 countries with half in five developed ones (USA, Canada, Russia, Australia, and NZ) and the rest in developing countries (Figure 1 and Table S2). Only —22% of primary forest is found in IUCN Protected Areas Categories I-VI (Table S3), which is approximately 5% of preagri-culture natural forest cover. About 35% of the world's preagriculture natural forest cover (61.5 x 106 km2) has been lost. There has been an estimated decline of 2.3 x 106 km2 in natural forests over the past 12 years (Hansen etal. 2013). Globally, 0.44 x 106 km2 of primary forest was impacted by logging and other human interventions from 2000 to 2010 (FAO 2010;. This global decadal estimate of 0.4% primary forest loss, however, is likely a significant underestimate as it excluded some high forest cover nations such as Democratic Republic of the Congo where 2% of its 1.1 x 106 km2 of primary forest was lost in this period (Zhuravleva etal. 2013).

Policy recommendations

Recognize primary forests as a matter of global concern within international negotiations

Deforestation and forest degradation are typically seen as a developing country problem. Primary forest protection, however, is a matter of global concern. Our analysis highlights that the distribution of primary forest, and rates of forest loss, are shared between developed and developing countries (Figure 1). Primary forest protection is also of global concern because of the role these forests play in planetary life-support systems, especially the global carbon cycle (Mackey et al. 2013), and in meeting international biodiversity and sustainable development goals (DellaSala et al. 2012). To date, attempts to negotiate an international forest treaty have failed and forests are treated in an ad hoc and uncoordinated way by relevant multilateral environmental agreements. However, significant opportunities exist for national governments to negotiate policies that promote primary forest protection through key international treaties, especially the UN Forum on Forests (UNFF), the Convention on Biological Diversity (CBD), the U.N. Framework Convention on Climate Change (UNFCCC), and the post-2015 development agenda and Sustainable Development Goals (SDGs).

A major impediment to policy emphasis on primary forests in international negotiations is the limited use made of science-based forest definitions. Since the early 1990s, there has been a move to a UN focus on "all types of forests" (including nonforest ecosystem types) to the exclusion of forests that are globally most significant ecologically or at risk. Primary forests are treated, by default,

as one of many "types" of forests and are not receiving the special attention they require to maintain their unique ecological conditions and ecosystem services. This generalized and nonscience-based approach to defining forests has dominated dialogue within the UNFF and has undermined the ability of the CBD, UNFCCC, post-2015 development agenda and SDG negotiations to explicitly recognize primary forests. The UNFCCC definition of forests, for example, fails to distinguish natural forests from plantations or primary forests from production forests; degradation is not clearly defined, leading to argument over whether industrial logging is a degrading activity; and the phrase "forest conservation" is understood to equate with maintaining forest cover rather than the protection of forest biodiversity, key forest structures like large old trees (Lindenmayer et al. 2014), and intact ecosystems (DellaSala etal. 2012).

Failure by national governments and international negotiations to adopt a shared and science-based definition of forests has enabled key assumptions to go unchallenged. These include that industrial logging can conserve all forest biodiversity and ecosystem services through sustainable forest management approaches such as reduced impact logging and variable retention harvesting (Gustafsson etal. 2012), despite evidence to the contrary (Zimmerman & Kormos 2012). A science-based approach to forest definitions would distinguish primary from both natural forests used for industrial logging and commercially planted forests (Table S4). Other categorizations are needed. For example, there are fundamental differences in forests across major climatic zones that must be recognized (Figure 1; Supporting Information). This will provide a far more robust platform for assessing the impact of policy proposals for forest management. International policy negotiations, unfortunately, remain under the influence of the decision taken in 1992 to adopt a "whole of forest" definition. The following sections consider some of the consequences.

Incorporate primary forests into environmental accounts

Another unchallenged assumption regarding how forests are addressed within the UN system has been that primary forests have minimal economic value. Thus, the economic value of their ecosystem services are not reflected in accounting and reporting systems. Significant progress, however, is being made in the development of ecosystem-based accounting that recognizes the qualities as well as the stocks and flows of natural assets (OECD 2013). Environmental accounts at a national level should provide data that informs government decision makers about the benefits and risks of land-use policies. The sig-

nificance of adopting a forest definition which explicitly includes primary forests becomes apparent here: environmental accounts can help inform policies that protect primary forest only if they recognize primary forests as a unique category of ecosystem and track their degradation and loss of intactness.

Environmental accounts can make a positive contribution to SDGs and the SDGs process has stressed the need for an ambitious and universal agenda that promotes transformational development approaches to eradicating poverty and protecting the planet's finite natural resources (UNDP & UNEP 2013). Recognizing primary forests as a distinctive class in environmental accounts would bring attention to the special contributions their ecosystem services make to SDGs including freshwater and associated watershed services. The distribution of forests and rainfall is highly correlated as photosynthesis and biomass production is a water-demanding process. The phenomenon of precipitation recycling is a well-documented positive feedback between forests and regional climate, for example, about half the precipitation in the Amazon originates from evapotranspiration (Salati et al. 1979). Intact forest landscapes exert a strong influence on catchment hydrology and the quality and flow of water. Forested watersheds reduce storm runoff, stabilize streambanks, shade surface water, cycle nutrients, filter pollutants, and their waters are often cooler with less sediment, nutrients, and chemicals than water from other lands (Furniss et al. 2010). Undisturbed forest with its understory, leaf litter and organically enriched soil is the best watershed land cover for minimizing erosion by water and any land-use activity that removes this protection increases erosion (Dudley & Stolton 2003). Intact forested watersheds therefore generally result in higher quality water than other land covers and alternative land uses such as logging which have been shown to increase sediment. Replacing old forests with young plantings often results in reduced water flow due to greater transpiration; disturbance can reduce the mean annual runoff by up to 50% compared to that of a mature forest, and can take as long as 150 years to fully recover (Jayasuriya et al. 1993). In a world heading to a population of nine billion people, potable and affordable water for human consumption will be an increasingly scarce and valuable resource (Dudley & Stolton 2003).

The U.N. Statistics Division's work on experimental ecosystem accounts provides the tool for national governments to begin testing and implementing systems that recognize the special ecosystem services, such as water flow and quality, arising from primary forests (OECD 2013). In implementing this approach, attention needs to be given to the quality of ecosystem stocks. In the case of primary forests, this includes tracking the impact on

them of roads. As the largest human artefact on Earth (>8 x 106 km globally), roads are usually the first infrastructure intrusion into primary forest. Roads are typically built initially for logging, fragmenting large intact forest blocks, and leaving the fragmented habitat highly vulnerable to biodiversity loss (Gibson et al. 2013) Roads allow the expansion of human settlements and enable other extractive land uses, especially agriculture, mining, and ranching (Forman et al. 2003). There are well-established relationships between roads and land-use development which overtime lead to deforestation, unless explicit mitigation measure are put in place (Bray etal. 2004).

Prioritize the principle of avoided loss

Both the climate change and biodiversity problems are at crisis points. International and national policies that aim to merely slow rates of land-use-related greenhouse gas emissions and species extinctions from primary forests are inadequate as we need to be fixing these problems at a faster rate than we are causing them. There is considerable merit, therefore, in emphasizing policies that seek to avoid any further biodiversity loss and emissions from primary forest deforestation and degradation by prioritizing the principle of avoided loss.

There is now extensive scientific documentation of the unique attributes of primary forests and the contributions they make to biodiversity conservation and carbon storage and sequestration. Loss of intact forests contributes directly to the biodiversity extinction crisis. Up to 57% of tropical forest species are dependent on old-growth forest habitat, with studies on regenerating forests showing that species recovery occurs over considerably longer time scales than vegetation structural regrowth, and that reestablishment of certain species and functional group composition can take centuries or millennia (Barlow etal. 2007). Intact forest landscapes contain large old trees and coarse woody debris which are among the most important substrates for the maintenance of species diversity, and are particularly important in temperate and boreal forests (Lindbladh etal. 2013). Intact forest is therefore irreplaceable for the maintenance of native species diversity and especially those obligate forest species found only in large remnants of native forest, with forest biodiversity generally declining along a coarse gradient from old-growth forest to secondary forest, agroforestry, plantations, arable crops, and pasture (Chazdon et al. 2009).

Clearing and logging of primary forest results in the depletion of ecosystem carbon stocks and increased carbon dioxide emissions to the atmosphere, exacerbating the climate change problem. Current forest biomass carbon stocks are estimated at around 289 Gt C, with as much again in the other forest ecosystem pools (soil carbon and

dead biomass) (FAO 2010). In total, emissions from land-use change, especially deforestation and degradation, are currently at least 10% of total annual anthropogenic emissions; comparable to emissions from the entire transportation sector (IPCC 2013). Since 1750, 33% of accumulated anthropogenic atmospheric emissions are from deforestation, degradation and other land-use changes (Houghton 2007). Primary forests store 30-70% more carbon than logged and degraded forests (Krankina & Harmon 2006; Bryan etal. 2010). A comprehensive approach to climate change mitigation is now needed: both fossil fuel and land carbon emissions must be curtailed. Avoiding emissions is now critical as a large fraction of anthropogenic climate change resulting from CO2 emissions is irreversible on a multicentury to millennial time scale. Keeping forests intact is therefore a priority mitigation strategy for avoiding land carbon emissions as complete deforestation could increase atmospheric carbon dioxide concentrations by 130-290 ppm (Mackey etal. 2013).

The CBD and UNFCCC provide opportunities for those national governments who are signatories to advance avoided loss policies. Under the CBD, parties have agreed to a Strategic Plan for Biodiversity 2011-2020 that includes 20 Aichi Biodiversity Targets. Primary forest protection is central to achieving at least five of these targets: natural habitat loss (Target 5); terrestrial land in protected areas (Target 11); ecosystems providing essential services (Target 14); contribution of biodiversity to climate change mitigation and adaptation (Target 15); and traditional and local communities (Target 18) (CBD 2010). Primary forest protection can be used in various ways to help achieve these Aichi targets. For example, Target 11 calls for an increase in the coverage of protected areas especially Key Biodiversity Areas (KBA—places of particular importance for biodiversity) (CBD 2013). Primary forests could be explicitly evaluated under the proposed KBA Criterion C: sites that are exceptional examples of ecological integrity and naturalness as represented by their intactness and regional continuity. An indicator addressing primary forest protection could be developed to monitor progress in achieving Targets 11 and 14.

While forests are acknowledged as playing important roles in climate change mitigation and adaptation globally (CBD 2009), current provisions on forests within the UNFCCC have significant failings with respect to primary forest conservation (DellaSala et al. 2012). The forest policy mechanism for developed countries with binding emissions targets listed in Annex 1 of the Kyoto Protocol (KP) is called Land Use Land Use Change and Forestry (LULUCF). For non-Annex 1 countries (developing countries including Brazil, India, and China), the equivalent mechanism is called Reducing Emissions from

Deforestation and Forest Degradation (REDD+). While forests are addressed by a plethora of policies, there are significant gaps regarding primary forests, in addition to the forest definition problem noted. REDD+, for example, is being negotiated as a set of only voluntary guidelines with financial incentives that will not be tied to national emission reduction commitments. There is a serious risk that in the post-2015 agreement there will be pressure to either continue or combine LULUCF and REDD+ without addressing current limitations of either. Conversely, opening up the negotiations on forests as part of a post-2015 agreement presents opportunities to strengthen definitions, improve rules, and develop a more coherent framework that provides strong incentives to protect all primary forest.

If national governments intend to comply with the international environmental treaties they have signed, then new policies are needed that provide incentives for avoiding logging-related emissions through forest protection rather than merely reducing the rate of emissions from land use. Within UNFCCC negotiations, mitigation benefits would be maximized by strictly prioritizing forest management activities in the following order (using the terminology of Decision 1/CP.13 of the Bali Action Plan): (i) "conservation" defined as avoiding emissions by protecting primary and other natural forests; ahead of (ii) "enhancement of forest carbon stocks" defined as sequestering CO2 by restoring degraded natural forests; ahead of (iii) "sustainable management of forests" defined in terms of reducing emissions through changed industrial logging practices. Currently, all three forest mitigation activities are recognized by REDD+ but they are poorly defined and are not prioritized. This deficiency was also noted by the European Union Parliament (2013). While this policy change may seem like a minor fine tuning, it is potentially a powerful lever that could significantly direct REDD+ investments in ways that provide incentives for national governments, local communities, and private landowners to protect primary forests. If this prioritization is not adopted, then REDD+ funds could end up doing little more than subsidizing industrial logging companies to undertake reduced impact logging/variable retention harvesting as presumed mitigation activities. Given the global distribution of primary forest, the need for international policies that direct funds and investments toward conservation actions that avoid emissions from primary forests is relevant in developed as well as developing countries.

Universal recognition of indigenous and community conserved areas

Governments could use primary forest protection as a mechanism within multilateral environmental agree-

ments to support sustainable livelihoods for the extensive populations of forest-dwelling and dependent people, especially traditional people, in both developed and developing countries. CBD Target 18 (indigenous and local communities) would be advanced through acknowledging the contribution of primary forest protection. Within the UNFCCC, primary forest protection could be recognized as a priority ecosystem-based adaptation activity providing cost-effective, no-regret options with multiple cobenefits for humans and nature (CBD 2009). Intact ecosystems can play a vital role in maintaining and increasing resilience to climate change (Thompson et al. 2009) and in reducing climate-related risk and vulnerability (UNFCCC 2011). Ecosystem-based adaptation approaches are typically no-regret options due to the coben-efits they provide in terms of mitigation, conservation and livelihoods and because they leave open future options.

The national government negotiators at the UNFCCC could agree, like has been done through the CBD process, to recognize the special contribution of indigenous and community conserved areas to protecting primary forests and, in light of the benefits these yield for both conventions, promoting policies that invest in capacity-building with local communities living in or near forest. Local people have strong incentive to preserve the forests they depend on as the basis of traditional subsistence uses including as a source of food, shelter, and medicine. There are many examples of successful natural ecosystem protection at all scales by local communities (Nepstad 2006). Primary forest have greater resilience to external stressors compared to degraded forests, including the new additional stress of anthropogenically forced, rapid climate change (Thomspon etal. 2009). The Amazon, for example, has resisted previous climate changes and should adapt to future climates as well if landscapes can be managed to exclude industrial land use and maintain natural fire regimes in the majority of forest remnants (Cochrane & Barber 2009). Formal recognition of indigenous and community conserved areas in the UN-FCCC negotiations could facilitate these communities' access to international climate change funds which they urgently need to provide them with the capacity and resources to protect primary forests.

Conclusions

International environmental negotiations are failing to halt the loss of the world's most important primary forests. While multiple stressors are at play in deforestation and degradation, and many nongovernment actors have important roles to play (Nepstad et al. 2014), national governments can help reset forest policies

globally by shifting away from addressing "all types of forests" generically toward a new regime based on the key principle that protection of primary forests is prioritized and accelerated. Enabling this shift also will require strengthening global policy coordination in support of primary forest protection across multilateral environmental agreements and UN processes, such as the UNFF, SDGs and the post-2015 development agenda. This will enhance synergies, strengthen cross-treaty linkages, avoid conflicting decisions, and help to develop appropriate financial mechanisms and responses in national action plans and programs.

The biodiversity impacts of industrial logging are chronically problematic in all forest biomes—tropical, (Zimmerman & Kormos 2012), boreal (Schmiegelow et al. 2006), and temperate (Lindenmayer et al. 2011)— with immediate, lagged, and cascading impacts. Complementary policies are needed that reduce pressure to open up primary forest for wood production and other intensive land uses by (a) shifting expansion of agricultural commodity production entirely out of primary forests to previously cleared land and (b) promoting restoration of degraded forest land. The 23 x 106 km2 of secondary forest (i.e., those subject to industrial logging or designated for multiple uses including wood production) provide vast areas of habitat for many species and ecosystem services (Putz et al. 2008) (albeit in a limited way relative to primary forests; van Bruegel et al. 2013). In addition to the mitigation benefits noted from avoided emissions, the potential contribution of forest restoration to reducing atmospheric carbon dioxide concentrations is significant (40-70 ppm if all cleared land was restored) (House etal. 2002). Secondary forests can serve as buffers and connections for primary forests and are important to landscape-wide conservation efforts (Crooks & Sanjayan 2006). Comprehensive forest protection is best achieved when both large and small blocks of primary forests are embedded within efforts to conserve and restore secondary forests more generally. Where forest is subject to industrial logging, therefore, changing logging practices and regimes so that they have lower emissions and biodiversity losses, and preventing management failures, are important components of a comprehensive landscapelevel approach to forest conservation. However, we caution against subsidizing industrial logging operations to mitigate their environmental impacts as there is no substitute for the unique biodiversity values and ecosystem services that primary forests provide.
