“…For the natural regeneration of A. chilensis under silvopastoral use, the output of the interaction of these contrasting stress factors is not straightforward, mainly because cattle is moved to other areas during summer, allowing a growing season without high herbivory pressure (Amoroso et al 2018). This seasonal livestock movement that characterizes silvopastoral use in the study area (Chillo et al 2021) may be a key issue that prevents failure of active restoration practices under chronic impacts (Ashton and Kelty 2018).…”

Ecological interactions, such as facilitation among plant species, has been identified as key for restoration actions. The stress-gradient hypothesis predicts that facilitation increases under harsh environments, but disturbance type and nurse shrub characteristics may modify this prediction. We aim at assessing the effect of two interacting factors (herbivory pressure and light availability) and palatability of the nurse shrub on the importance of nurse effect for active restoration of mixed evergreen forests of northern Patagonia (Argentina) for silvopastoral use. We planted Austrocedrus chilensis seedlings under two silvopastoral use intensities (higher and lower according to livestock seasonal movements) and under three micro-site treatments (palatable shrub, non-palatable shrub, inter-canopy), and evaluated survival and growth during three consecutive years. Under higher use intensity (increasing stress of light availability as desiccation risk and herbivory) we found contrasting effects of the nurse effect on seedling survival and growth, but the palatability of nurse shrub had no effect. Under higher use intensity, seedling survival was lower, while growth was higher. Higher values of seedling survival were found under low use intensity inter-canopy microsite. Under high use, the presence of a nurse shrub is important for summer seedling survival, indicating its role in avoiding desiccation. The same occurred for winter seedling survival, where a nurse shrub may decrease mainly trampling risk. We highlight the importance of considering the interaction between disturbance factors for the net outcome of the nurse effect in active restoration actions, as it may allow for diverse actions to restoration.

“…Oerst., que sostienen la carga ganadera durante la mayor parte del año (entre 8-9 meses), proporcionando refugio y alimento. Sin embargo, están poco estudiados como parte de los sistemas productivos de la región (Chillo et al 2021;Arpigiani et al 2022). La ganadería en esta región suele acoplarse con actividad silvícola, aunque con escasas pautas de manejo en su integración (Cardozo 2014;Amoroso et al 2021;Chillo et al 2021), por lo que denominamos a la actividad como "uso silvopastoril".…”

Las clausuras en bosques templados se han usado con frecuencia para evaluar los efectos del ganado con objetivos de conservación y restauración. Sin embargo, su empleo con objetivos de manejo en sistemas productivos integrados a bosques nativos está poco estudiado. Dado que los estudios se concentran en el hemisferio norte, es fundamental avanzar en investigaciones locales que aporten herramientas de manejo que garanticen la continuidad del componente forestal y la funcionalidad del sistema. Por ello, analizamos la respuesta de la vegetación a la exclusión temporal del ganado en sistemas silvopastoriles en bosques mixtos de Austrocedrus chilensis - Nothofagus dombeyi de la Patagonia norte. Evaluamos cambios en la estructura, la composición y la funcionalidad de la vegetación del sotobosque, así como en la regeneración de las especies dominantes del dosel. Seleccionamos tres predios de productores medianos y en cada uno establecimos parcelas abiertas y clausuras pareadas que se monitorearon durante tres años. Las clausuras afectaron de forma significativa el crecimiento en altura de los renovales de N. dombeyi y marginalmente la supervivencia de plántulas de A. chilensis, mientras que la riqueza de especies, la composición, la cobertura y la diversidad funcional del sotobosque no mostraron cambios. La cobertura de especies palatables no se vio afectada, posiblemente debido a la mayor limitación por luz que por la herbivoría y al corto tiempo de exclusión analizado. Bajo las condiciones estudiadas, la exclusión comunitaria de corto plazo no parece una herramienta conveniente en un manejo predial para promover la producción de forraje o la regeneración de las especies forestales más sensibles.

“…These findings provide thresholds for regeneration survival, allowing us to develop more sustainable silvicultural practices. We suggest to follow a strategy of adaptive management [33,67,68] based on long-term monitoring of local extreme climate events, e.g. PEBANPA network [28].…”

Regeneration is crucial for forest continuity in natural and managed stands. Analyzing intra-annual dynamics improves the understanding between growth and climate, identifying survival thresholds. The objective was to determine microclimate constraints (rainfall, air and soil temperatures) over Nothofagus antarctica regeneration growing at closed, open, and edge forests in Patagonia. We measured stand characteristics (forest structure, understory, soil properties, animal use), microclimate, and daily growth of regeneration using dendrometers (n = 6) during two growing seasons. We found significant differences in the studied variables (e.g. overstory, light, soil, understory, animal use). These changes defined microclimate across overstory gradient (e.g. soil moisture), influencing the daily growth across seasons (lag, exponential, stationary). Rainfall influenced more than temperature. Daily growth in closed forests indicating shrinkage (-0.0082 mm day-1 without rain, and -0.0008 mm day-1 with 0.0-0.2 mm day-1 rainfall), while above 0.2 mm day-1 rainfall, growth always increased. Open forests presented shrinkage during days without rain (-0.0051 mm day-1), showing positive growths according rainfall. Edge forests always presented positive daily growths. The resilience of regeneration under these changed conditions was related with overstory. Main outputs indicated that regeneration was vulnerable during non-rainy days, suggesting the needs of long-term monitoring to develop better silvicultural proposals.
