With the declaration of the Nazca-Desventuradas Marine Park in 2016, 13.6% of the EEZ is now protected, which added to the 19.5% protection of the land, satisfies the commitment under the CDB Aichi Target 11 (17% of terrestrial and inland water areas and 10% of coastal and marine areas). However, despite these promising numbers, Target 11 also requires that areas are “conserved through effectively and equitably managed, ecologically representative and well-connected systems of protected areas and other effective area-based conservation measures…”. The results of the present work show that Chile remains far from reaching this international commitment, which is set for 2020, as just 84 of the 145 PAs and only five of the 20 MPAs are being managed. This is a recurrent problem and a subject of analysis worldwide as evidenced by the increasing number of publications focused on studying the real capacities and shortcomings of the governments that have subscribed to the CBD agreements to properly manage their protected land and marine territories [1, 2, 6, 10, 14, 15, 18,19,20, 30, 36].
Even though the Aichi Targets encourage a holistic approach to biodiversity conservation, in which the land and sea is viewed as an interconnected ecosystem [34], the differences among the PAs and MPAs in Chile in terms of coverage, representativeness and management are abysmal [32]. As an example, the Malleco Forest Reserve was created in 1907 as the first terrestrial protected area in Chile, but it was not until 1997, almost a century later, that the first marine protected area (La Rinconada MR) was established [16]. Thus, since there is a longer history of protection on land, the practice of creating management plans is also older. This is clearly reflected in that 79.66% of the total protected land area is under a management plan, but this is the case for only 0.017% of the ocean area under protection, i.e., only five Marine Reserves. This has probably also been influenced by the resource-based goals of the first Chilean MPAs, which focused on protecting the giant mussel (Choromitylus chorus) at Putemún MR, the Chilean oyster (Tiostrea chilensis) at Pullinque MR, and the northern scallop (Argopecten purpuratus) at La Rinconada MR to sustain economic activity instead of preserving ecological value. It was not until 2007 that the first management plan for an MPA was developed in Chile for the Islas Choros-Damas Marine Reserve, which was based on the methodology used for the national parks in France, specifically the Port-Cros National Park [8], and implementation only began in 2017.
Furthermore, the Chilean marine area under protection is more than three times larger than the total terrestrial area under protection (463,115 km2 vs 151,466 km2), but there is an enormous asymmetry in the representativeness of the protected marine ecoregions as most of the marine area is covered by two large-scale marine parks, Nazca-Desventuradas with 300,035 km2 in the Desventuradas Ecoregion and Motu Motiro Hiva with 150,000 km2 in the Easter Island Ecoregion, both of which are located around remote, uninhabited oceanic islands in the Chilean Pacific territory. Less than 1% of the other six marine ecoregions, which largely correspond to continental Chile (except for Juan Fernández), are protected [16, 32]. This is not the case for terrestrial protection since the SNASPE (Wild Protected Areas National System) includes 145 protection zones distributed throughout the country, representing most terrestrial ecosystems in different proportions [25]. Martinez-Tillería [23] showed that only three of 12 terrestrial ecoregions satisfy the 17% conservation goal; among the most unrepresented (less than 1% under protection) terrestrial ecoregions are the Chilean Matorral and Central Andean Puna, both of which have high levels of biodiversity and endemism [32].
One of the reasons for the above mentioned asymmetry in marine ecoregions is that remote uninhabited regions are subjected to a low level of use and, consequently, have low potential for conflicts among stakeholders in contrast to heavily used and populated coastal areas [36]. Continental Chile has large coastal cities, fishing, mining and salmon farming, among other heavy-impact economical activities, which makes conservation of biodiversity an extremely difficult task [32]. Leenhardt et al. [19] suggested that large-scale marine protected areas (LSMPAs) became a popular conservation tool for governments during the last decade due to their appearance as a solution for reaching conservation targets. This, combined with the low level of use compared to continents, make oceanic ecoregions the best candidates for reaching the 10% global target even though representativeness is low. At the global scale, just 36% of all marine ecoregions (N = 232) have at least 10% of their area under protection [34]. This situation is detrimental in terms of misdirecting conservation efforts and the consequent loss of biodiversity, but it also directly affects the objectives (e.g., maintaining large-scale ecosystem services, protecting the home ranges of large migratory species, etc.) of contributing to the collective functioning of the global protected area network [30].
The picture was even worse when the effectiveness of the existent management plans was evaluated, since only a 22.2% of the plans and none of the marine plans were effective. On land, this was due, in part, to the age of the plans as 64.2% (5% in the ocean) were older than 10 years, so we assumed that they have not been revised since initially being proposed. This means that the boundaries of the actual PAs as well as the activities and regulations implemented to reach the conservation goals in each area may be outdated. Although there is little literature on the appropriate time to revise management plans, methodologies and manuals for the design and management of LSMPAs around the world indicate that management plans should be revised every 5 years to respond to changes in the initial conditions or emergent threats (e.g., a major environmental disaster) in a timely manner [21].
One hundred percent (N = 16) of the terrestrial management plans that successfully passed the two effectiveness criteria used as filters corresponded to plans created in 2014 using the Technical Manual N° 23 "Method for Planning the Management of Protected Areas" by CONAF. It is important to emphasize that this manual significantly improved the effectiveness of management plans, but exhaustive work is still necessary for this effectiveness and efficiency to extend through all six steps (Context, Planning, Inputs, Processes, Outputs and Outcomes) of the IUCN-WCPA framework [13, 34]. Integrating the Outputs and Outcomes steps would allow each protected area to be evaluated based on the results after its creation and would answer key questions such as "What did we do and what products or services were produced?" and “What did we achieve?” This would assess whether managers and stakeholders were able to achieve the established priority goals in addition to measuring the actual effectiveness of the management actions in fulfilling the conservation objectives on which the establishment of the area was based [13].
Of the 16 management plans classified as effective, one corresponds to the Juan Fernández Archipelago (oceanic islands in central Chile), two to central Chile (VII Region) and the other 13 to southern Chile, leaving the central zone (described as one of the 25 “hotspots of global biodiversity” [26]) and the north of the country almost without any effective protection. For example, Pingüino de Humboldt NR and Los Flamencos NR, two of the most important protected areas in the central and northern areas of the country, received 53,294 and 310,698 visitors, respectively, during 2015 (in the second case, the maximum number of visitors allowed by the SNASPE), and neither were classified as being effectively managed according to our methodology. Considering Aichi Target 11, conservation must be performed in an effective, equitable and efficient manner, so this objective has not been met in much of the country.
Our analysis only incorporates the first four steps of the PAME methodology and was focused on scrutinizing the management plans for each area as opposed to directly measuring the effectiveness of this management approach in reducing biodiversity loss or the evolution of conservation objectives. Nevertheless, this methodology is still a good indirect approach for understanding the administrative and biodiversity reality of the national PA network by contrasting the local scenario with the international context. Coad et al. [6] indicated that the number of effectiveness assessments of management plans around the world increased drastically between 1990 and 2014, but UNEP-WCMC & IUCN [34] showed that only 17.5% of participating countries had reached the target by February 2015. This indicates that most of the PAs in Chile and worldwide, both terrestrial and marine, may not be achieving their initial goals or that they were not correctly assessed a priori.
One of the main restrictions to management and thus the full implementation of protected areas may be financial support [14]. Waldron et al. [35] indicated that Chile is among the 10 most underfunded countries for biodiversity conservation in the world, and this status is shared with developing and underdeveloped countries such as Malaysia, Iraq and Senegal. Specifically, a 2016 report by the Organization for Economic Cooperation and Development (OECD) indicated that only US$1.3 per hectare were invested for protection in Chile, a quantity that is significantly lower compared to other South American countries such as Argentina (US$10), Colombia and Brazil (US$4). However, although funding is considered the greatest obstacle, it is not always clear that this is the case in Chile. Figueroa [7] estimated that adding US$35 million to the SNASPE per year would result in more effective management and monitoring of protected areas, but a simple analysis indicates that this is not the only key to solve the problem. Considering only the territory on land, the correlation between the amount of money designated for 68 protected areas in the SNASPE in 2016 versus the number of visitors and management plans for each creates a confusing picture. According to our criteria, only 11 PAs of the 68 analyzed have an effective management plan, but none receive more than 27,000 visitors per year in 2016 and they account for only 8.18% of the total allocated funds. In contrast, the second most visited protected area, Torres del Paine NP, received more than 200,000 visitors and more than US$2,527,900 per year in 2016, which represents 15.29% of the total funds raised by the entire SNASPE. However, this PA did not pass any of the effectiveness filters. Therefore, funding should not be considered the main obstacle to reach effectiveness, but instead a deficient level of organization. For example, Batista & Cabral [1] found that the highest levels of effectiveness in MPAs in South-Western Europe were due to factors such as high stakeholder participation, well-defined objectives and high levels of funding oversight.
In the SNASPE, the administration of each unit is based on a historical basis, underestimating the need for management plans updates, this not been considered an intrinsic activity of the PA management, thus needing for special funds and extra time allocation for the personnel. In the marine realm, MPAs are not only a recent tool, but they also originally started with a resource-based focus [16]. Moreover, the governance system is characterized by several sectoral agencies, not necessarily coordinated, that overlap in the ultimate goal of marine conservation [3]. This is a key limitation to e.g. implementation of ecosystem-based management in Chile, but also means that use of funds is not efficient, by duplicating actions. A new Biodiversity and Protected Areas Service (SBAP), as a coordinating entity of all terrestrial and marine protected areas could help for the solution, by avoiding discoordination and including the update of the management plans as one of its priority tasks. However, this long-time wanted project is still in the Chilean Parliament with no clear date for implementation [32].
Considering all the protected areas in Chile, the vast majority of management plans were considered null (older than 10 year, 61.6%) or deficient (not effective, 17.4%), which placed them in the internationally recognized category of “Paper Parks” [2]. One strategy that could help to solve this problem is a reappraisal of the existing protected areas, particularly the older ones, followed by the generation of adaptive and updated management plans because the protection targets for each conservation object may have changed. This will also require collaboration among the stakeholders, NGOs, donors, scientists, international partners and every institution working in the area to establish a shared vision to optimize procedures and consequently achieve results. The focus of the National Protected Areas Administration System must be on generating long-term and large-scale biological conservation strategies, which requires contemplation of the entire national territory as a great reservoir of biodiversity, leaving behind the concept of PAs as isolated areas and instead considering the entire Chilean PA network [16, 30, 32, 34]. Only in this way will local and global targets be achieved, effectively contributing to the preservation of different-scale conservation goals (e.g., ecosystems, biodiversity hotspots, ecosystem services, habitats, endangered species, highly migratory species, high–trophic-level species, target fisheries specie, etc.).
Because of the remoteness of some ocean territories and the great challenge of effectively implementing LSMPAs, a question arises as to whether this type of protection is really feasible in countries such as Chile that have large and remote ocean territories, limited resources, and no experience in their effective management. Major threats to biodiversity such as climate change, land-use change, overexploitation, habitat destruction and invasive species are occurring at regional and global scales. Therefore, despite the difficulty in their implementation, LSMPA networks are the appropriately sized tools for dealing with macro-scale threats to biodiversity as opposed to small-scale PAs. Thus, if large-scale protected areas are effectively managed, in combination with international scientific-political cooperation, and designed with a global perspective, they would provide knowledge of and solutions to the effects of human activities on global biodiversity. The LSMPA trend in Chile is recent, starting with Motu Motiro Hiva Marine Park in 2010. Further promising advances are being made as the Nazca-Desventuradas Marine Park is now the first LSMPA in Chile to have a management plan, proposed only 20 months after the area declaration [9].
It is clear and well understood that the establishment of new protected areas is fundamental to “ensure normal evolutionary processes occurring in a functional ecological scenario” [31] and this should incorporate Systematic Conservation Planning to avoid any bias [24, 32]. However, in the Chilean context, it is very important to consider the actual national scenario and the investment available for conservation (e.g., limited funds, inadequate administrative structure, etc.) before continuing adding protected areas to the national system without a good assessment of threats and needs, especially when support for the existing areas is insufficient to satisfy basic requirements (e.g., enforcement, management plans, rangers, outreach activities, etc.). It is fundamental that the Chilean government evaluates the performance of protected areas respect to their original objectives, including effective management. This could be facilitated by a collaborative work with different stakeholders to put PAs in a local context and promote the engagement of local communities in nature conservation and management. Locally managed MPAs by municipalities, local organizations or foundations could be a way to cope with this major gap. The Locally Managed Marine Areas (LMMAs) in the Pacific Islands could work as a successful example for communities for conserving their resources through community-based management [11, 29].
On the other hand, it is urgent that governments around the world take action to diminish the human footprint on the planet and meet international conservation targets. It is our obligation not only to maintain each element of the biodiversity that surrounds us but also to ensure a better future for coming generations. It is time to admit and embrace the idea that the economic development of a country must go hand in hand with the conservation of its natural heritage to ensure its protection over the long term. In this way, Chile could keep being positioned as an example of conservation worldwide.
