“…Mediterranean abandoned vineyards therefore produce an improvement in organic matter throughout the secondary succession. Tabeni, Yannelli, Vezzani, and Mastrantonio (2016) found that old fields (> 40 years of abandonment) recovered nutrient cycling functionality at the landscape level.…”

European abandoned lands have been increasing in recent decades, and this is occurring in a climate change scenario in which the consequences of their interactions are still little known. We tested the hypothesis that the functionality of abandoned lands responds differently to year‐to‐year climate variations depending on the time since the cessation of agricultural activity. We constructed a chronosequence in Mediterranean abandoned vineyards at six different years of abandonment in 2016 (1, 3, 7, 11, 25, 40), in a current vineyard and in land not dedicated to vineyards. Soil total organic carbon (TOC), total nitrogen (TN) and available nutrients, enzyme activities relating to the main macronutrient cycles and plant‐community attributes were studied at 24 sites over three consecutive years. A total of 144 samplings were performed. TOC, TN, most enzyme activities and plant species density increased throughout the chronosequence, although interannual climate variability also had a significant influence. The extreme drought event increased the activity of enzymes related to the carbon (C) and nitrogen (N) cycle, as well as the stock of TOC after a subsequent decrease in TOC when environmental conditions became favourable. In contrast, plant species density and the cover of certain plant functional traits such as mycorrhizal symbiotic plants (Cistaceae) and N‐fixers (Fabaceae) decreased significantly. Our results also demonstrated that extreme drought events had a higher negative impact on lands that had been abandoned for longer. We therefore conclude that extreme drought events damage the functionality of Mediterranean abandoned agrosystems, thus affecting all its compartments and jeopardising its functionality.

“…As noted in the reserve, 50 years of domestic grazing removal promoted an increment in the abundance-dominance or frequency of the main palatable grasses as well as some species of shrubs (Rossi 2004). Also, the increase of plant cover restored the spatial arrangement of vegetation patches and consequently reestablished landscape connectivity (Tabeni et al 2016). Thus, for the purpose of this study, the reserve can be considered as an undisturbed area.…”

Interactive effects of chronic anthropogenic disturbances on Prosopis woodland structure in the Central Monte, Argentina

et al. 2022

In drylands all over the world, chronic anthropic disturbances are relevant factors for woodland degradation. Different disturbances can potentially interact to change vegetation structure. Knowing woodland structure is crucial for be�er predicting forest dynamic because trees of different sizes significantly affect the regeneration processes, number of saplings and young trees, crown traits and competition a�ributes. Throughout the Monte biogeographic region, grazing and wood extraction are the main anthropogenic disturbances on Prosopis dry woodlands that can generate modifications in key ecosystem processes. First, we aimed to assess woodland structure at sites under chronic anthropic disturbances. Subsequently, we explored how the combination of grazing and wood extraction affected the population structure of P. flexuosa considered by classes: seedlings, saplings and adults. We found that sites under disturbances presented a high density of trees of smaller sizes. Besides, the interaction effect between grazing and wood extraction depended on the intensities of each of the disturbances. The combination of high intensities of both grazing and wood extraction negatively affected the abundance of all classes, but low or moderate grazing intensities combined with high wood extraction had a positive effect on the abundance of saplings and adults. High intensities of co-occurring disturbances decreased seedling abundance affecting forest recruitment which also was negatively reflected in sapling and adult abundance. However, the combination of low or moderate grazing and high wood extraction generated a woodland structure characterized by few seedlings, and many saplings and adult trees of small size. Application of management options (e.g., spatial or temporal separation of human use, programmed management of grazing and wood extraction intensities or planned practices as wood removal for local use) should contribute to enhance the provision of ecosystem services in Prosopis sp. woodlands without risking regeneration persistence and improving the woodland structure.

“…En la RBÑ (denominada en adelante como área protegida), las actividades extractivas y la ganadería fueron excluidas por ~50 años, lo cual condujo a un aumento en la abundancia y la cobertura de pastos palatables y de algunas especies de arbustos (Rossi 2004). El incremento en la cobertura de plantas permitió la recuperación en la disposición espacial de los parches de vegetación y, en consecuencia, el restablecimiento de la conectividad del paisaje (Tabeni et al 2016). Por lo tanto, el área protegida se toma en este trabajo como un punto de comparación con las áreas vecinas donde las actividades humanas se han mantenido.…”

En el Monte Central, Neltuma flexuosa es la principal especie arbórea con importantes funciones ecológicas y socio-culturales. En esta región, la ganadería integrada al bosque nativo, en combinación con prácticas silvícolas, es la forma más extendida de utilización del bosque. Estas actividades humanas pueden generar cambios en la dinámica del bosque que, a su vez, está condicionada por la disponibilidad hídrica. Nuestro objetivo fue evaluar el patrón de crecimiento de árboles de N. flexuosa del Monte Central y asociarlo a distintos usos del suelo y al clima. Se emplearon métodos dendrocronológicos para analizar muestras de madera extraídas en áreas destinadas a conservación, uso ganadero y extracción de madera. Se observó que los árboles del área con extracción de madera crecieron entre los años 1977 y 2000 aproximadamente dos veces más que los individuos de los campos ganaderos y del área protegida, para luego reducir su crecimiento a niveles similares a los registrados en las otras dos áreas. Mientras las máximas tasas de crecimiento en el área de extracción se alcanzaron entre los 20 y 40 años de edad de sus individuos, en el área protegida y en los campos ganaderos se presentaron alrededor de los 70 años. Además, se observó una asociación positiva pero baja de las precipitaciones con el crecimiento. Los resultados indican que los usos del suelo han afectado el patrón de crecimiento radial de los árboles de N. flexuosa. La capacidad de rebrote de la especie habría facilitado su recuperación a nivel de árbol, lo cual combinado con un cambio en la intensidad de uso humano posibilitó la recuperación de la población de N. flexuosa y el restablecimiento del bosque. Estos resultados sugieren que la ganadería extensiva y la extracción de madera para uso doméstico son actividades compatibles con el uso sustentable del bosque.
