“…Under this physiognomic type are different botanical communities, and biodiversity is dynamically changing due to the spread to abandoned agricultural areas on the one hand, and the existence of fires on the other hand. Monitoring of such ecosystems is necessary in order calculate biovolumes to infer biomass, or CO 2 , as shrubs are involved in combustible models (calculating fire risk) and the modelling of post-fire shrub restoration in combination with soil analysis [43]. In the case of soil modelling, the second derivate transformation allows, by post-processing manipulation, for the identification of proper spectral properties [44,45].…”

The Mediterranean ecosystem exhibits a particular geology and climate, which is characterized by mild, rainy winters and long, very hot summers with low precipitation; it has led to the emergence of resilient plant species. Such habitats contain a preponderance of shrubs, and collectively harbor 10% of the Earth's species, thus containing some of the most unique shrubby formations protecting against environmental natural degradation. Due to shrub species diversity, initial phases of forestland, heterogenous grasses, bare ground and stones, the monitoring of such areas is difficult. For this reason, the aim of this paper is to assess semi-automatic classifications of the shrubby formations based on multispectral Sentinel-2 and visible and near infrared (VINR) AISA-EAGLE II hyperspectral airborne images with a support of Canopy High Model (CHM) as a three-dimensional information and field-verified patterns, based on Match-T/DSM and aerial photos. Support Vector Machine (SVM) and Random Forest (RF) classifiers have been tested on a few scenarios featuring different combinations of spectral and Minimum Noise Fraction (MNF) transformed bands and vegetation indices. Referring to the results, the average overall accuracy for the SVM and AISA images (all tested data sets) was 78.23%, and for the RF: 79.85%. In the case of Sentinel-2, the SVM classifier obtained an average value of 83.63%, while RF: 85.32%; however, in the case of the shrubland, we would like to recommend the RF classifier, because the highest mean value of F1-score achieved was 91.86% (SVM offered few-percent-point worse results), and the required training time was quicker than SVM. Commonly available Sentinel-2 data offered higher accuracies for shrubland monitoring than did the airborne VNIR data.

“…vegetation afforestation) are implemented to assist and facilitate the recovery of native plant communities and habitats after a wildfire. These types of treatments are usually applied in areas degraded by recurrent wildfires that prevent the natural regeneration of vegetation (García Matallana et al 2022). Among burnt wood management strategies, cut plus lopping treatment, where burnt trees are cut and felled, main branches being lopped off and cut wood left on the forest floor (Marañón-Jiménez et al 2011), are usually applied to promote the natural recovery of the vegetation by climate amelioration (Taboada et al 2018) and increase post-fire wildlife diversity (Lindenmayer and Noss 2006).…”

“…Many studies have recently evaluated the effect of mulching and burnt wood treatments on post-fire soil chemical properties and carbon content (Gómez-Rey et al 2013;Pierson et al 2019), microbiological communities (Fontúrbel et al 2012;) and hydrological features (Prats et al 2021), as well as on the composition and structural properties of plant communities (Duniway et al 2015;Taboada et al 2018;Jonas et al 2019;García Matallana et al 2022). Nevertheless, forest ecosystems provide a wide variety of functions and services (ecosystem multifunctionality sensu Garland et al 2021).…”

Background. Mulching and burnt wood treatments are commonly applied to prevent the loss of soil quality and erosion, but their effect on soil multifunctionality remains unexplored. Aims. We filled this gap by assessing the medium-term (4 years) effects of these treatments on soil multifunctionality after a large wildfire in NW Spain. Methods. Straw mulching (SM) and cut plus lopping (CpL) treatments were applied in high-severity affected areas of heathland plant communities. CpL areas had been afforested with Scots pine 15 years before the fire. We considered four soil functions estimated in treated and burned control plots 4 years after fire:(1) carbon regulation; (2) water regulation; (3) soil fertility; and (4) nutrient cycling. The functions were integrated into a multifunctionality index and linear models were used to evaluate treatments effect. Key results. SM had no impact on individual functions and multifunctionality. Conversely, CpL with burnt Scots pine wood was able to sustain higher levels of multiple functions simultaneously than control areas. Consistent trade-offs between soil functions emerged in control areas for both treatments. Conclusions. Burnt wood could ensure longlasting effects to promote soil multifunctionality in Mediterranean ecosystems. Implications. We recommend using a multifunctionality approach to avoid biases in treatment success.

“…Many studies have evaluated the effectiveness of these practices on individual ecosystem properties in soil (erosion, runoff…) (Gómez-Rey et al, 2013;Prats et al, 2021) and vegetation (species richness, vegetation cover...) (Duniway et al, 2015;García-Matallana et al, 2022) but ecosystems provide multiple functions and services at the same time (ecosystem multifunctionality sensu Garland et al, 2020). Ecosystem multifunctionality could be considered as the ability of an ecosystem to supply multiple ecosystem functions and services increasing the benefits that societies can be obtain from an ecosystem (Hölting et al, 2019;Liu et al, 2021).…”

Wildfires are a widespread phenomenon in forests across the Mediterranean Basin but have increased in severity and extent in recent decades. Post-fire treatments are measures that help recover burned vegetation and their functionality but to what extent they also help recover soil functionality is currently unknown. The main objective of this study was to assess the effect of post-fire treatments on ecosystem multifunctionality after a large wildfire in the Cabrera mountain range in 2017 (NW Spain) where close to 10000 Ha of forest were burnt. At the end of 2017 and during 2018, the administration applied different post-fire treatments in high fire severity affected areas: i) straw mulching, ii) woody debris and iii) subsoiling and iv) mechanical hole afforestation. In each treatment, we established ten 2 x 2 m plots and ten adjacent untreated burned plots and collected a composite soil sample from each plot four years after the fire (2021). We calculated regulating services as the standardized mean of total soil organic C (climate regulation), soil water repellence (water regulation) and soil aggregation (soil protection). Supporting services were measured as the standardized mean of mineral N-NH4+ and N-NO3- and available P (soil fertility), Î²-glucosidase, urease and acid phosphatase (nutrient cycling) and microbial biomass (soil quality). Ecosystem multifunctionality was measured as the standardized mean of all functions measured. Application of straw mulch and woody debris increased regulating ecosystem services in relation to burned control plots. Afforestation with holes had not impact but subsoiling decreased regulating ecosystem services in relation to burned control plots. Post-fire treatments did not have any effect on supporting services. Straw mulch, Woody debris and afforestation with holes improved ecosystem multifunctionality when compared with subsoiling methods. These results show that post-fire stabilisation treatments, in particular straw mulching have a significant positive impact on regulating services and are effective measures in restoring the ecosystem multifunctionality, helping develop effective management based-decisions for the recovery of ecosystem services and functioning after large wildfires.
