Geodiversity and Geoheritage data from Alagna Valsesia, Sesia Val Grande UGGp (NW Italy)
<p>Geodiversity and geoheritage are concepts that have gained popularity in recent years for managing territories by promoting geoconservation and sustainable development. For example, geoparks, areas recognized by UNESCO and considered among the best examples of promoting informal education, geoconservation and geotourism of an area, are growing in number and importance. However, establishing the role and potential use of the geodiversity map in geoconservation and geoheritage recognition remains a complex task. In fact, there are numerous methodologies proposed to assess geodiversity, which can be summarized in 2 categories: qualitative method and quantitative method. These methods assess different characteristics of geodiversity and, from a geoconservation perspective, could be complementary tools.</p> <p>To explore the potential use of the quantitative geodiversity map and its association with geoheritage, we provide here files of Alagna Valsesia, a mountainous area located at the foot of Monte Rosa Massif, NW Italian Alps, within the Sesia Val Grande UGGp. Specifically, these data have been collected for the following pourposes:</p> <ol> <li>Map geodiversity (shapefiles of geodiversity units and DTM of Alagna Valsesia);</li> <li>Inventory and mapping of geosites (shapefiles of geosites containing, in addition to the location, information on the importance and interests of the geosites, useful for land managers for their promotion and conservation);</li> <li>Statistical calculation of correlation between geodiversity and geoheritage in the field (R language script useful for calculating this correlation, which challenges the potential use of quantitative map for geosite recognition).</li> </ol> <p>The data represent original data for the following publication:</p> <p>Michele Guerini, Alizia Mantovani, Rasool Bux Khoso, Marco Giardino (2024).

Geodiversity data for Europe at 1-km and 10-km resolutions
<p>The European geodiversity data provides a novel perspective on the diversity of non-living nature over large spatial extents. These data describe geological, pedological, geomorphological, and hydrological diversity, including 78 different geofeatures. Geofeatures refer to individual features that each component of geodiversity (geology, pedology, geomorphology, and hydrology) consists of, such as soil types in the case of pedology. This standardized and accessible geodiversity dataset facilitates comparability for geodiversity research across Europe and can be used for multiple purposes, from studying geodiversity patterns to geodiversity–biodiversity relationship and more. Moreover, the methodology (described in <a href="https://dx.doi.org/10.1098/rsta.2023.0173" target="_blank" rel="noopener">Toivanen et al. 2024</a>) establishes a grid-based approach for quantifying geodiversity, which is suitable for large extents and can be applied in other regions worldwide.</p> <p>This grid-based geodiversity dataset, available at resolutions of 1-km and 10-km, includes ready-to-use georichness variables (as GEOtiff files), and provides information on the presence and coverage of individual geofeatures that can be used to calculate different measures of geodiversity (as csv files). The data on georichness can be utilized in its entirety, representing the overall geodiversity, or with selected geodiversity components as individual richness layers describing geological, pedological, geomorphological or hydrological feature richness. One key objective of this geodiversity data is to provide complimentary environmental variables for biodiversity modelling and conservation studies. However, the choice of geodiversity data (richness or other index), the scale of analysis (1-km or 10-km), and the specific variables (overall geodiversity or individual components) should be determined by the research question and context.</p> <p>This is a dataset from: Toivanen, M. et al.

Case study data of the paper: A methodological guide to observe local-scale geodiversity for biodiversity research and management
<p><span>Current global environmental change calls for comprehensive and complementing approaches for biodiversity conservation. According to recent research, consideration of the diversity of Earth's abiotic features (i.e., geodiversity) could provide new insights and applications into the investigation and management of biodiversity. However, methods to map and quantify geodiversity at local scale have not been developed although this scale is important for conservation planning. </span><span>Here, we introduce a field methodology for observing plot-scale geodiversity, pilot the method in an Arctic-alpine tundra environment, provide empirical evidence on the plot-scale biodiversity-geodiversity relationship and give guidance for practitioners on the implementation of the method</span><span>.</span></p> <p><span>The field method is based on observation of geofeatures, i.e., elements of geology, geomorphology, and hydrology, from a given area surrounding a location of species observations. As a result, the method provides novel information on the variation of abiotic nature for biodiversity research and management. The method was piloted in northern Norway and Finland by observing geofeatures from 76 sites at three scales (5, 10 and 25 m radii). To explore the relationship between measures of biodiversity and geodiversity, the occurrence of vascular plant species was recorded from 2 m x 2 m plots at the same sites.</span></p> <p><span>According to the results, vascular plant species richness was positively correlated with the richness of geofeatures (R<sub>s</sub> = 0.18–0.59). The connection was strongest in habitats characterized by deciduous shrubs. The method has a high potential for observing geofeatures without extensive geological or geomorphological training or field survey experience and </span><span>could be applied by conservation practitioners</span><span>.</span></p> <p><span>Consideration of geodiversity in understanding, analysing and conserving biodiversity could facilitate environmental management and ensure the long-term sustainability of ecosystem functions. With the developed method, it is possible to cost-efficiently observe the elements of geodiversity that are useful in ecology and biodiversity conservation. Our approach can be adapted in different ecosystems and biodiversity investigations. The method can be adjusted depending on the abiotic conditions, expertise of the observer(s), and the equipment available.</span></p>
