A National Park split by an internal border. Analysing the case of Sierra de Guadarrama (Spain)

In countries characterized by a high degree of decentralization, the limits between their main administrative units – that is, their ‘internal borders’ – with jurisdiction over protected natural areas prove critical for their management. This article analyses a national park split by just such an internal border, its objective being to determine the extent to which this border compromises the classic notion of a national park and how it impacts its management. The case study described is that of the Sierra de Guadarrama National Park, located in the centre of Spain, straddling the autonomous regions or communities of Castile and León and the Community of Madrid. The study exploits qualitative techniques, specifically semi-structured interviews with prominent actors in this territory, which allow us to analyse their perceptions of the national park and the implications of the border between the two autonomous communities in which it lies. Our research shows that the effects of internal borders can be similar to those of a border between two States, and that in decentralized countries the concept of transboundary protected areas is valid at the intra-state level. Additionally, the important political role played by national parks at different scales is verified as is the fact that cooperation between Spain’s autonomous communities remains weak.

Drivers of Batrachochytrium dendrobatidis infection load, with evidence of infection tolerance in adult male toads (Bufo spinosus)

Chytridiomycosis is affecting hundreds of amphibian species worldwide, but while in tropical areas, adult individuals have been the focus of most investigations, the exact role played by infection intensity of breeding adults is not well understood in temperate areas. We conducted mark–recapture–capture surveys during spiny common toad breeding seasons from 2006 to 2018 at the site of the first recorded outbreak of chytridiomycosis in Europe, the Peñalara Massif (Sierra de Guadarrama National Park, central Spain), and collected infection samples and several variables related to the reproductive effort of male individuals. We used general linear mixed models to evaluate the contribution of study variables on the infection loads of adult male toads exhibited at their capturing date. We also analysed the differences on several male characteristics between the pond with the largest breeding population against the rest of the ponds. We found that the duration of time spent in the waterbody and the condition of the host predicted infection loads. Animals of good physical condition, that spent longer in water, have higher infection levels than individuals with the opposite set of traits. The pond supporting the largest breeding population housed smaller male toads and in poorer condition. Our results are consistent with a shift in reproductive strategy in response to infection and potentially a strategy of tolerance, rather than resistance to infection. These findings have applications for disease mitigation and theoretical implications related to the trade-offs made and the evolution of traits in response to the disease.

Visualizing stakeholders’ willingness for collective action in participatory scenario planning

Participatory scenario planning is a powerful approach to guide diverse stakeholders in creating and reflecting on visions of plausible and desired futures. However, this process requires tools to guide collective action to implement such visions within management agendas. This study develops, applies, and analyzes a novel visual tool within a virtual participatory scenario planning process about the Sierra de Guadarrama National Park (Madrid, Spain). Building on the identification of stakeholders who might engage in scenario strategies, the visual tool guided them in defining tasks to be developed and envisioning their willingness to collaborate in their implementation. We qualitatively analyzed data from recordings, online field observations, a post-survey from the scenario planning process, and a successive policy workshop. Our findings show that the visual tool fosters dialogue between stakeholders to redistribute tasks for working together on needed strategies in the protected area while promoting reflection on their willingness to collaborate as a group to implement them. The visual tool provided graphic outcomes for nine strategies corresponding to pictures of who may or may not be willing to engage in implementing such strategies. We argue that the visual tool is a robust method that can complement participatory scenario planning processes by providing a useful starting point for creating action networks to incorporate the resulting scenario strategies into management agendas. We deliberate on the nature of the visual tool as a boundary object and discuss its role as a decision-support tool. In particular, we reflect on the potential contributions and limitations of the visual tool to four dimensions of participatory conservation governance during participatory scenario planning processes: inclusivity, integration, adaptation, and pluralism. Our study provides a practical orientation to adapt the tool to other contexts and knowledge co-creation processes.

Amphibian survival compromised by long-term effects of chytrid fungus

Chytridiomycosis, the disease caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), has been unambiguously implicated in the decline of amphibian populations worldwide. However, the impact of this devastating infectious disease can be difficult to gauge without empirical data on the population-level effects of Bd. Often, assessments of the amphibian chytridiomycosis panzootic are based primarily on expert opinions; as a result, declines in tropical areas are promptly attributed to Bd while its impact on temperate species not suffering from adult mass mortalities is frequently overlooked. Here, we investigated the survival probability in an amphibian species from a temperate area that until now has not been considered to be severely impacted by the disease. Specifically, we related individual survival to Bd infection status using long-term capture-mark-recapture data of male spiny common toads (Bufo spinosus) in Sierra de Guadarrama National Park in central Spain. Even though the study population has demonstrated potential for adaptation to Bd and die-offs of adult individuals have not been recorded, our results clearly indicated that the probability of survival was lower for Bd-positive individuals. Moreover, the probability of becoming Bd-positive was higher than the probability of clearance, driving the population to a slow but certain decline. These results are consistent with other indicators of a negative population trend and suggest that the impact of Bd on temperate species of less concern may be greater than previously thought.

The expansion process of the Iberian ibex in the Sierra de Guadarrama National Park, Madrid (Spain)

In this paper we explore the usefulness of MaxEnt to predict the most suitable areas for a wildlife species, the Iberian ibex (Capra pyrenaica). For two decades (1990–2010), the species was established in a small part of the National Park Sierra de Guadarrama (Spain) and there has been a process of expansion to other areas of this protected area since 2010. However, almost two decades have elapsed since the modeling methods (MaxEnt) were proposed and no studies have tested their effectiveness using real distribution data, i.e. data from past predictions, to see if they fit the current distribution. We generated a model with presence– only data from 2007 and verified accuracy from 2017 data concerning real presence. Our results show a relationship between models and the species' current presence. The generated model can be useful to define the preferred locations of the species. We detected several differences between males and females of the species. This work not only shows the importance of selecting climatic and ecological variables for the construction of models but also indicates that they must be adjusted, at least for some species, to each sex and period of the year.

Collembola from Two Samplings in the MSS of the Sierra de Guadarrama National Park in Two Different Seasons, with Description of a New Species.

An intensive sampling in a colluvial mesovoid shallow substratum (MSS) of the Sierra de Guadarrama National Park, using 33 subterranean sampling devices (SSDs) is the origin of the Collembola studied in this paper. The data were obtained from the second extraction of the traps, in operation between October of 2015 and May of 2016. This paper presents the faunistic and diversity data along with the entire park (mostly at sampling points above 200 m a.s.l.) for this period, compares the data between the first extraction of the traps and the second one, and describes one species of the genus Pseudosinella that appears as new in the second campaign.

Moss cover and browsing scores as sustainability indicators of mountain ungulate populations in Mediterranean environments

Here, we aimed to define ecological indicators of environmental change for monitoring the effect of a reintroduced species, the Iberian ibex (Capra pyrenaica), over the vegetation of a natural protected area with contrasting habitats. This species was reintroduced 30 years ago in the Sierra de Guadarrama National Park, Spain, and its population has since grown exponentially, reaching high densities in some areas. We tested the suitability of two complementary indicators: browsing damage on woody species and the percentage of moss cover loss on rocky outcrops. For this purpose, we used a mathematical approach to zone the natural protected area according to the historical presence of the species and established five different Iberian ibex pressure classes (Classes I–V). Our results showed a direct link between Iberian ibex pressure and vegetation status. Model predictions suggested 10% moss loss in the areas with low pressure (Class I) but 64% loss in the areas with high pressure (Class III), mostly due to ungulate trampling on rocks. Similarly, browsing damage increased with increasing pressure classes for different woody species. Low palatable plant species such as Pinus spp. showed little change in browsing damage for increasing ungulate pressure whereas more palatable plants (e.g., Erica arborea) showed significantly greater browsing damage variation across pressure classes (i.e., high sensitive to herbivory pressure). Both, moss cover on rocks and widely distributed palatable woody plants proved useful ecological indicators for monitoring ungulate populations in mountainous areas with a diverse array of habitats (e.g., rocky vs. woody). This methodology may help select the most suitable indicators for each type of ecosystem or dominant habitat in ungulate-dominated ecosystems.

Summit typology and detailed geomorphological landscape units mapping through the application of direct and indirect methods. A case study in the Sierra de Guadarrama National Park, Spain

This paper analyzes the topography and the geomorphological characteristics of the central sector of the Sierra de Guadarrama (Spanish Central Range) from the point of view of the geomorphological landscape. Using Digital Elevation Models (DEM) and topographic maps, the aim is to supplement conventional geomorphological analysis by applying indirect morphometric methods for the detailed study of landforms through topographic analysis in order to obtain maps of diverse morphometric parameters, resulting in an exhaustive study, which is useful and revealing both in terms of geomorphology and of landscape. The morphometric maps obtained for each variable, such as the density of the dissection, the depth of the dissection and the energy of the relief, are overlaid on the derived maps from the DEM using Geographical Information System (GIS). Their analysis, using both indirect and direct methods during several field studies, in combination with the geology and the geomorphology of the study area, allows a more accurate study of the unit delimitation of the geomorphological landscape at a detailed scale. In a mountainous environment with smooth and apparently homogeneous summits, this detailed study of the geomorphological landscape shows the existence of different types of summits. The results are presented as a typology of summits and a map synthesizing the detailed units of geomorphological landscape that can be found in the Sierra de Guadarrama National Park (Central Spain).

Ecological impact of recreational bathing at Las Presillas (Lozoya River, Sierra de Guadarrama National Park, central Spain)

The ecological impacts of recreational uses on the rivers of Sierra de Guadarrama National Park (SGNP) have been scarcely studied. To assess the impacts of these uses at Las Presillas (an area with small dam along a section of the Lozoya River), and in the Lozoya River (upstream and downstream of the dams), the dynamics of the organic seston (FPOM), physicochemical variables (electric conductivity, dissolved oxygen, Temperature, and pH) and biological variables (fecal coliforms, fecal streptococci, and aquatic macroinvertebrates) during the recreational (July to September) and nonrecreational (October) periods were assessed. The variations observed in the physicochemical parameters were associated with autumnal influence. However, at Las Presillas, different values were found than at the rest of the surveyed sites, characterized by an increase in the concentration of FPOM and, human fecal contamination (although they did not reach dangerous levels) and the response of the macroinvertebrate communities, which resulted in a clear decrease in the IBMWP index and other quality metrics, during the recreational period. These findings suggest that the combined effects of the dams and recreational activities at Las Presillas generate functional dynamics in that alter the habitat in summer. The identification and study of these impacts through the application of innovative indices and quality classes that integrate and contextualize Las Presillas in the SGNP monitoring network, have been identified as key management and conservation tools.

A combination of cosmogenic and Schmidt hammer exposure dating in the study of the deglaciation timing of Sierra de Guadarrama National Park (Spain)

ABSTRACT The objective of the work is to calibrate the Schmidt hammer exposure dating (SHD) method in the Sierra de Guadarrama National Park in correlation with the dates previously obtained by Cosmogenic Radiation Exposure (CRE) dating methods. The dates were recalculated according to the new production models of 36Cl and 10Be cosmogenic isotopes. For this purpose, three glacial cirques were selected (Dos Hermanas, Laguna and Pepe Hernando), located on the eastern slope of Peñalara Peak, Spain (40°51'N, 3°57'O; 2428 m), the highest altitude of this mountain range. The application of the SHD method seems to be influenced neither by the different altitude of the samples nor by their height with respect to the current ground level. The degree of roughness of the rock surfaces (gneiss) has a slight influence, but does not change the actual volume of the results. The results of this work show a clear relationship between the CRE ages and the SHD R-values. The oldest landforms (31–19 ka) give mean values R < 50, both for moraine boulders and polished bedrock. The boulders of a rock glacier (16–15 ka) and the boulders of the innermost moraine yielded higher values: R-value >50. The youngest polished bedrock surface, located under the Peñalara Peak (12–11 ka), yielded R-value >60.

Cholevinae (Coleoptera: Leiodidae) of the Sierra de Guadarrama National Park, Spain: occurrence in the MSS of a siliceous landscape

In siliceous landscapes, study of the mesovoid shallow substratum (MSS) provides interesting species records. The Cholevinae Kirby, 1837 are normally found in the forest litter, and they also are a constant element in underground habitats. However, their knowledge is totally lacking in relation to the underground realm of Sierra de Guadarrama National Park (Spain). Over the period of a year, the MSS of this mountain range was prospected to acquire first insights into the Cholevinae species established in this habitat. The prior literature was reviewed to establish an initial checklist of the Cholevinae species in the National Park, and distributional maps of the captured species were provided for the area. Twelve species of Cholevinae were captured, five of which are new records for the National Park, four for the province of Segovia, and one for the province of Madrid. All the species present wide Iberian ranges, except Choleva (Choleva) cisteloides (Frölich, 1799), whose new record notably expands its known distribution range. Ten species had been identified in subterranean habitats before, six of which have been previously reported in the MSS. The species accumulation curve built for the observed species richness showed that the inventory was not complete. Finally, the collection of Choleva (Cholevopsis) punctata Brisout, 1866 facilitated detailed study of the taxonomic characters used for the identification of Choleva (C.) punctata and Choleva (C.) securiformis Blas, 1980, allowing us to propose the synonymisation of C. (C.) securiformis n. syn. into C. (C.) punctata. This study highlights the importance of investigating hidden habitats, such as the MSS in siliceous landscapes, so as to uncover the previously unknown biodiversity, even in protected natural areas supposedly well studied.

How stable are visions for protected area management? Stakeholder perspectives before and during a pandemic

Abstract Envisioning processes enable protected area managers to chart a course for future management to reach desired goals, but unexpected changes that could affect future visions are not usually considered. The global COVID‐19 pandemic provided an opportunity to explore changes in stakeholder visions, the values that underpin the visions, and their perceptions of landscape changes and the underlying drivers (e.g. climate change, mass tourism and demographic trends). Through a mixed‐methods approach in this post‐evaluation study, we gathered comparative data on these issues from stakeholders in the Sierra de Guadarrama National Park, Spain, between July 2019 (pre‐pandemic) and October 2020 (mid‐pandemic). Our qualitative analysis demonstrates that pre‐pandemic, differences in visions for protected area management were largely spurred by different perceptions of drivers of change, rather than differences in values or perceived landscape changes, which were similar across different vision themes. One year later, in the midst of the COVID‐19 pandemic, the majority of stakeholders reported that their values, visions and perceptions of drivers did not change despite this large‐scale disturbance. Of the 20%–30% of stakeholders that did report changes, visions generally shifted towards greater prioritization of biodiversity and nature conservation as a result of heightened perceptions of the impacts of drivers of change associated with an increase in the numbers of park visitors. These drivers included mass tourism, mountain recreation, lack of environmental awareness, and change in values and traditions. Our findings reinforce the importance of adaptive and inclusive management of protected areas, including enhancing transparency and communications regarding factors driving change in the landscape, and integration of local and traditional knowledge and stakeholder perceptions of changes and drivers. Furthermore, management plans integrating stakeholder values have the potential to stay relevant even in the face of wildcard events such as a pandemic. To enhance the relevancy of visions and scenarios in conservation and land‐use planning, scenario planning methodologies should more strongly consider different potential disturbances and how drivers of change in the near and far future can be affected by wildcard events such as a pandemic.

A pressure indicator for the impact of Iberian wild goat on moss and soils in a Mediterranean climate

In the Sierra de Guadarrama National Park (central Spain), the population of Iberian wild goat, also known as Spanish ibex (Capra pyrenaica) has grown strongly since its reintroduction three decades ago. The plant community is now under heavy browsing pressure due to this high population. A study of the presence of moss on rocks was used herein as the basis for the design of an indicator, named impact on mosses (im), to describe the environmental pressure exerted by the Iberian wild goat in terms of moss removal. Granite and gneiss zones at medium altitudes with continental Mediterranean climate are the most suitable areas for successful application of the indicator. The hypotheses to test are: (1) the indicator will discriminate between areas with different wild goat pressure levels, (2) wild goat pressure will explain a high proportion of moss loss variance, and (3) the im indicator will be useful to establish a mathematical model between wild goat pressure and moss loss. The proposed indicator was analyzed using both statistical and data science techniques. The results support the mentioned hypotheses. Specifically, statistically significant differences were found regarding the impact on mosses between areas with different levels of Iberian wild goat pressure. Thus, a high proportion of the variance was associated with wild goat pressure (80% for high-pressure areas, 56% for low-pressure areas). A modified parabolic function was fit to express the relationship between Iberian wild goat pressure and impact on mosses. In conclusion, the im indicator was shown to be a useful tool to assess pressure due to Iberian wild goat. Therefore, im can help assess and manage Iberian wild goat populations and determine their sustainable levels.

Spatial Scale Dependence of Ecological Factors That Regulate Functional and Phylogenetic Assembly in a Mediterranean High Mountain Grassland

Understanding how functional and phylogenetic patterns vary among scales and along ecological gradients within a given species pool is critical for inferring community assembly processes. However, we lack a clear understanding of these patterns in stressful habitats such as Mediterranean high mountains where ongoing global warming is expected to affect species fitness and species interactions, and subsequently species turnover. In this study, we investigated 39 grasslands with the same type of plant community and very little species turnover across an elevation gradient above the treeline at Sierra de Guadarrama National Park in central Spain. In particular, we assessed functional and phylogenetic patterns, including functional heterogeneity, using a multi-scale approach (cells, subplots, and plots) and determined the relevance of key ecological factors (i.e., elevation, potential solar radiation, pH, soil organic carbon, species richness, and functional heterogeneity) that affect functional and phylogenetic patterns at each spatial scale. Overall, at the plot scale, coexisting species tended to be more functionally and phylogenetically similar. By contrast, at the subplot and cell scales, species tended to be more functionally different but phylogenetically similar. Functional heterogeneity at the cell scale was comparable to the variation across plots along the gradient. The relevance of ecological factors that regulate diversity patterns varied among spatial scales. An increase in elevation resulted in functional clustering at larger scales and phylogenetic overdispersion at a smaller scale. The soil pH and organic carbon levels exhibited complex functional patterns, especially at small spatial scales, where an increase in pH led to clustering patterns for the traits related to the leaf economic spectrum (i.e., foliar thickness, specific leaf area, and leaf dry matter content). Our findings confirm the presence of primary environmental filters (coldness and summer drought at our study sites) that constrain the regional species pool, suggesting the presence of additional assembly mechanisms that act at the smallest scale (e.g., micro-environmental gradients and/or species interactions). Functional and phylogenetic relatedness should be determined using a multi-scale approach to help interpret community assembly processes and understand the initial community responses to environmental changes, including ongoing global warming.

Neelipleona and Symphypleona (Collembola) from a Sampling in the Mesovoid Shallow Substratum of the Sierra de Guadarrama National Park (Madrid and Segovia, Spain): Taxonomy and Biogeography.

Simple SummaryThe material for this study was obtained after intensive sampling in the colluvial mesovoid shallow substratum (MSS) of the Sierra de Guadarrama National Park using 33 subterranean sampling devices (SSD). The data were obtained from the first extraction of the traps between May and October of 2015. This paper presents the results for a small part of the total Collembola captured (4.4% of the total for this sampling), namely, the Neelipleona and Symphypleona. Eleven species belonging to seven families were identified, two of which are new species. Based on the results of this study, and others previously published on Collembola of the MSS in the Sierra de Guadarrama National Park, the presence of epigeal and edaphic species is observed, which, in general, are not as abundant as the newly discovered species. The high abundance and extensive presence in the hypogean environment of most of the new species discovered are indicative that the MSS has a unique and distinct Collembola community.Megalothorax minimus (Neelidae) and Sphaeridia pumilis (Sminthurididae) had already been identified in surface sampling from Sierra de Guadarrama. In Europe, Sminthurinus gisini (Katiannidae) seems to be associated with environments at specific altitudes, and has little representation in this sampling. Pygmarrhopalites custodum Baquero and Jordana sp. nov. (Arrhopalitidae) coexists with two previously identified surface occurring species of the same family (P. elegans and Arrhopalites caecus). However, P. custodum is more abundant, indicating that it occupies an ecological niche tending to troglophile in the mesovoid shallow substratum (MSS). Moreover, it is also more abundant in the MSS of higher altitude corresponding to the bioclimatic zones cryo-oro-Mediterranean and oro-Mediterranean supra forest. Allacma cryptica Baquero and Jordana sp. nov. (Sminthuridae), is another species that had not been previously detected on the surface in the study area. A. cryptica is an addition to a genus which has eight described species. Gisinurus malatestai (Sminthuridae) appears well represented in the MSS, being a species present very occasionally in the Mediterranean area. Two species of the genera Sminthurides (Sminthurididae) and Fasciosminthurus (Bourletiellidae) have been found, but they could not have been identified to the species level. Finally, a few specimens of Dicyrtomina minuta (Dicyrtomidae), an abundant species on the surface, have been captured.

Society's preferences when ecological values and health risks are at stake: An application to the population control of a flagship ungulate (Iberian ibex) in Sierra de Guadarrama national park, Spain

Conflicts derived from the proactive management of ecosystems and wildlife populations abound in national parks, which can prevent the control of some animal populations, consequently causing negative effects to the ecological values and creating health risks for the ecosystems. This work quantifies a conflict related to population control of the Iberian ibex in the Sierra de Guadarrama National Park in Spain where ecological values and health risks are at stake. A discrete choice experiment was conducted of three population samples: 430 on-site visitors, 210 off-site visitors and 210 non-visitors, and two levels of status quo information were considered. The results show that not conducting any ibex management program in the park causes a loss of social well-being and that the design of the management program is shown to be relevant for obtaining greater or lesser acceptance by the surveyed population. In general, better ecological and health levels, as well as avoiding having to kill animals in the park, increase a program's acceptance. Management measures are also shown to take on greater importance to the extent that the results in the health and ecological indicators are worse. Finally, in aggregate terms, additional information about the status quo did not generate major differences in the estimates of a change of well-being. • Visitors and residents of the area state that the ibex must be managed in the park. • No ibex management produces a loss of well-being higher than the park's annual budget. • If the ibex management plan is not successful, how it is done becomes more important. • Live capture and culling are accepted if the results of the program are effective. • The definition of the status quo has no major effects on preferences.

Distinctive Collembola Communities in the Mesovoid Shallow Substratum: Entomobryomorpha of the Sierra de Guadarrama National Park (Central Spain)

The material for this study was obtained after intensive sampling in the colluvial mesovoid shallow substratum, or MSS, of the Sierra de Guadarrama National Park using 33 subterranean sampling devices (SSD). The data were obtained from the first extraction of the traps between May and October of 2015. This paper presents the results for the Entomobryomorpha Börner, 1913, which was part of the Collembola captured. Four families and 12 genera have been studied: Isotomidae Schäffer, 1896 (Folsomia Willem, 1902, Tetracanthella Schött, 1891, Uzelia Absolon, 1901, FolsomidesStach, 1922, IsotomurusBörner, 1903, Parisotoma Bagnall, 1940, PseudisotomaHandschin, 1924 and Pachyotoma Bagnall, 1949), Orchesellidae Börner, 1906 (OrchesellaTempleton, 1835 and Heteromurus Wankel, 1860), Entomobryidae Schäffer, 1896 (Entomobrya Rondani, 1861) and Lepidocyrtidae Wahlgren, 1906 (Lepidocyrtus Bourlet, 1839 and Pseudosinella Schäffer, 1897). The species of Orchesella were studied in a previous paper (Baquero et al. 2017). The richness of the habitat sampled is defined by twenty-one species, eight of which are new: Pachyotoma penalarensis Baquero & Jordana n. sp., Entomobrya guadarramensis Jordana & Baquero n. sp., Entomobrya ledesmai Jordana & Baquero n. sp., Lepidocyrtus labyrinthi Baquero & Jordana n. sp., Lepidocyrtus paralignorum Baquero & Jordana n. sp., Lepidocyrtus purgatori Baquero & Jordana n. sp., Pseudosinella valverdei Baquero & Jordana n. sp. and Pseudosinella gonzaloi Baquero & Jordana n. sp. Entomobrya intermediaBrook, 1884 (England) is discussed and a new name Entomobrya katzi Jordana & Baquero n. sp. is proposed for E. intermedia sensu Katz et al. (2015) based on the American specimens.

Delineating participation in conservation governance: Insights from the Sierra de Guadarrama National Park (Spain)

The active participation of local stakeholders in governing protected areas is increasingly recognized in biodiversity conservation. While progress has been made in countries to facilitate inclusivity in conservation decision-making, there is limited practical guidance of participatory mechanisms enabling stakeholder engagement. Disentangling formal and informal governance arrangements within protected areas illuminates how stakeholder participation in decision-making is shaped and potentially improved. Here, we provide an analytical framework characterising governance arrangements to examine the formal and informal mechanisms guiding stakeholder participation conservation decision-making in the Sierra de Guadarrama National Park (Spain). We conducted 76 semi-structured interviews and field observations with local stakeholders, and reviewed Park policy documents. Our findings reveal governance arrangements are contingent upon stakeholders’ responsibility (shared vs. concentrated) and influence (equal vs. unequal), regardless of the (in)formality of decision making. We found four types of arrangements that characterise governance of Sierra de Guadarrama National Park—cooperative, consultative, informative, and prescriptive—and identified the mutually supportive role formal and informal mechanisms play in shaping participation. We argue stakeholders’ responsibility and influence are key analytical axes to delineate participatory mechanisms in order to identify challenges and opportunities for more inclusive conservation. Our study provides analytical guidance that could be adapted and scaled up to other protected areas for understanding participation in conservation decision-making.
