Integration of Instruments for the Protection of Natural Protected Areas in Urban and Biodiversity Strategies and in Urban Planning Regulations

Approximately 75% of the urban settlements in Romania are superimposed or are tangent to at least one natural protected area, these not being integrated from the point of view of their regulation in the urban strategies and in the urban planning regulations. From a spatial point of view, this type of relationship often represents a contrast between the urban fabric and the quasi-natural fabric. However, in the regulatory or strategy instruments for the development of urban settlements, where such contrasts exist, they are only integrated at the border level. The ecotone is, in most cases, the only element mentioned in urban planning instruments and is approached as a land that can only function in isolation and that in no way can support urban development. This reluctance and fear of approaching natural protected areas, also negatively influences the conception of the community, investors and the administration. Urban actors are not informed and therefore not motivated, but neither do they have the opportunity to get involved in the conservation and protection process. The purpose of this article is to research urban and biodiversity strategies at E.U level, to identify gaps in the formulation of urban planning tools, what are the reasons behind generating these gaps and how they can be eliminated, or at least mitigated. The analysis will focus on some models of urban strategies which address natural protected areas, but will also consider related elements, directly related to their conservation, urban ecology and the involvement in the process of urban actors.

Spatial distribution and fluctuating populations of predatory mites (Mesostigmata: Phytoseiidae), phytophagous mites (Acari: Eriophyidae, Tetranychidae) and their relationships with wild chili pepper phenological stages in two Natural Protected Areas of Mexico

Ecological interactions between mites (predatory and phytophagous) and wild plants growing in undisturbed environments play a crucial role to understand their natural settlement, development and dispersion patterns. Pequin chili pepper, Capsicum annuum L. var. glabriusculum, is a low-cost natural resource for local communities living inside Natural Protected Areas (ANP) of Tamaulipas State in Mexico. The aims of this research work were: 1) determine the spatial distribution pattern of predatory and phytophagous mites, 2) determine the spatiotemporal association between predatory and phytophagous mites, and 3) determine the association among different mite species and some phenological stages of Pequin chili pepper. The most abundant phytophagous mites were Tetranychus merganser and Aculops lycpoersici, and the predatory species were Amblyseius similoides, Euseius mesembrinus and Metaseiulus (Metaseiulus) negundinis. Most mite species showed an aggregated distribution pattern according to the plant phenological stages. However, the distribution of mite species throughout time showed different types of aggregation. On the other hand, we found positive associations among A. lycopersici and T. merganser phytophagous mites with A. similoides, E. mesembrinus and M. (M.) negundinis predators mites. The association between plants and mite species were influenced by the phenological stages of Pequin chili pepper. This is an indication of the complexity among trophic-chain interactions that depend largely on the available resources and competition. These two factors serve as foundations for settlement, development and dispersion patterns of certain species.

Short-Term Abandonment versus Mowing in a Mediterranean-Temperate Meadow: Effects on Floristic Composition, Plant Functionality, and Soil Properties—A Case Study

Hay meadows are secondary grasslands maintained by mowing, and their ecological importance resides in the inherent biodiversity and carbon stocking. We investigated the plant community and soil properties of a sub humid acid grassland near the Fucecchio marshes (Italy), managed as a hay meadow, mowed once a year, and not fertilized. Part of the meadow had been abandoned for three years. We analysed the soil properties (i.e., organic carbon and total nitrogen content, available phosphorus, pH, cation-exchange capacity, texture, and conductibility) and the plant community structure (composition, functionality, and species richness) of the two sides of the meadow (mowed and abandoned). Our aim was to highlight the changes in soil properties and vegetation community, and to find out to what extent abandonment can affect those dynamics. Our results showed that after short-term abandonment, soil pH, C and N increased; litter biomass and perennial forbs increased; and annual forbs decreased. New species colonising after abandonment, thus enriching the flora, may keep spreading and eventually hinder the growth of the specialists if mowing is not resumed. Certain valuable meadow habitats need constant human intervention to maintain their peculiar vegetation, most especially if they are a buffer zone in the proximity of natural protected areas.

Challenges for the Integrated Management of Priority Areas for Conservation in Tamaulipas, México

Protected areas (PAs) are considered as a globally accepted strategy for biodiversity conservation that demonstrates the difficulties in meeting the proposed objectives; therefore, different conservation schemes are promoted to integrate the design of interfaces that favor the exchange of knowledge among different sectors, systems and stakeholders. The objective of this study was to characterize challenges regarding the protection of natural protected areas and other biodiversity conservation schemes in Tamaulipas, Mexico. This paper analyzed 39 areas with some form of protection status in addition to the 70 national and international designations that are part of them. A document review and 13 semi-structured interviews were conducted with experts from the public, private, academic, and civil society sectors. The data were analyzed from a qualitative perspective using ATLAS.ti 9 software. The results show the overlapping of protection schemes in priority areas; the lack of policies and mechanisms that integrate the different schemes to facilitate the exchange between stakeholders; and regulatory, structural, governance, management, participation, and operational gaps, as well as the absence of comprehensive and long-term work. The importance of and challenges in articulating the different schemes and visions to achieve effective biodiversity conservation are evident.

The Assessment of the Tourism Potential of the Tagus International Nature Reserve Landscapes Using Methods Based on the Opinion of the Demand

There are different methodologies to assess landscape preferences, however there is no consensual methodology that can be replicated to identify their tourism potential. Recent studies have focused on agricultural landscape preferences due to their cultural characteristics. Although agricultural activity conflicts with the management models of natural protected areas, traditional models and sustainable practices reveal opportunities to boost tourism in this area, both for their aesthetic value, and for the opportunity to preserve biodiversity and maintain “lively landscapes”. The present study focuses on a double approach to collect data to measure the preferences for landscape typologies to realize outdoor/recreative activities in Tagus International Nature Reserve (TINR), among them, agricultural landscapes, such as the agro-silvopastural system “Dehesa/Montado” or olive grove. The preference of the landscapes were evaluated through photographs with pairwise comparison and without photographs observation, in which 174 respondents were consulted with. The different methodologies applied allowed for the extraction of different results, which led to the assumption that in fact there is no single methodology to assess preferences. However, the application of the analytic hierarchy process (AHP) methodology with photographical pairwise comparison allowed for the extraction of more robust results when considering attractions with tourism typologies, revealing that “Cultural tourism/Rural mixed” and “Agritourism” were the most valued. This information is pertinent to support TINR managers and local tourism promoters to plan and structure products and services based on button-up methodologies.

Ecological Vulnerability of Adult Female Marine Turtles as Indicators of Opportunities for Regional Socioecosystem Management in the Southern Gulf of Mexico

Planning for marine ecosystems management demands spatially explicit information about structural and functional components, in a tradeoff between including the most taxa and keeping it functional. Sentinel, umbrella, and surrogate taxa are strategic for developing indexes that account for other associated species and contribute to a sustainable administration of our seas. Marine turtles feature the former species descriptions, and the knowledge on their ecology contributes to design conservation and restoration strategies in regions they occupy, such as the Gulf of Mexico. Several administrative tools exist to govern marine territories for biodiversity conservation, and assessing how these tools interact with the ecological vulnerability of endangered species is crucial for improving public policies. We assessed the spatial interactions among ecological sensitivity, vulnerability, and the potential impacts on four marine turtle species in the southern Gulf of Mexico and northwestern Caribbean Sea with territorial management tools (natural protected areas, marine priority sites, and ecoregions). A small percentage of the most vulnerable areas is inside natural protected areas, while marine priority sites include a higher percentage. We identified spatial covering gaps that need to be addressed to ensure the conservation and recovery of these endangered species in the Gulf of Mexico and proposed key regions for maximizing territorial conservation.

Geochemical evaluation of soils, surface and groundwater from natural protected areas from Romania. Case studies.

The purpose of this article was to present an assessment of the soil and water quality in some protected areas from Romania in order to establish a series of geochemical thresholds on a spatial and temporal scale. The activities and results presented in this article are based on extensive monitoring, being stage results because the monitoring activities will continue, the project is ongoing. Two protected areas, Cheile Nerei -Beusnita National Park and Piatra Craiului National Park were selected. Surface water, groundwater samples, and soil samples were collected in 2019, respectively 2021 from 16 sampling sites situated in both locations. For each sample, twenty quality parameters/indicators were analyzed and the values were compared with in-force legislations. For Arsenic, Copper, and Nitrates parameters have plotted the distribution of the values in each site. In future monitoring activities, the evolution of the parameters will be followed.

Quantitative methodology for the estimation of the environmental impact of wind farms – The case of Greece and application on the country’s operating units

Following the EU guidelines towards a carbon free electricity sector by 2050, wind energy is expected to contribute a large part of the produced electricity, if not the largest. In this respect, wind installations are expected to multiply over the next years. There is significant development until today and wind is generally considered as a “clean” source of energy. However, although arguably less than other sources, the impacts concerning wind installations are certainly there amidst ever-growing local opposition and will certainly grow, especially in locations with high density. Attempting to quantify the total impacts per local regions in the case of Greece, a methodology is developed for those impact factors that are considered the most important. Certain focus areas are used for applying this methodology, based on installation density, location inside natural protected areas, as well as locations of touristic value. The results show that in general the total impacts might be considered on average mild to low. The tool developed is a first attempt to evaluate impact in a cumulative way and help investors, policy makers and local communities work together in achieving the best possible outcome. Further work is necessary to further develop this methodology, verify and detail the formulas used and establish a robust pattern that will be a useful tool for everyone to use.

Avocado Cover Expansion in the Monarch Butterfly Biosphere Reserve, Central Mexico

Avocado cultivation has reduced the extent of forest ecosystems in central Mexico, even in natural protected areas such as the Monarch Butterfly Biosphere Reserve (MBBR) where information on the extent and expansion dynamics of avocado cover is scant. This study aimed to identify avocado plantations within the MBBR through photo interpretation for the 2006–2018 period. Change rates of the avocado cover extent were calculated for the northern, central, and southern zones of the MBBR, and topographic attributes such as elevation, soil type, slope, and slope aspect were identified. A total extent of 958 ha is covered by avocado plantations within the MBBR. The southern zone hosted the largest area under avocado cultivation (570 ha), but the northern zone had the highest change rate between 2006 and 2018 (422%). Most avocado orchards have been established mainly in Acrisol soils, south-facing slopes, on steep hillsides, and in elevations between 2050 and 2800 m. The conversion from traditional agricultural lands has been the main mechanism for the establishment of avocado orchards. However, 40 ha under avocado cultivation derived from deforestation, mainly in the central zone. The expansion of avocado plantations could trigger environmental impacts, even threatening the overwintering habitat and the migratory phenomenon of the monarch butterflies.
