“…También se analizó la variación del número de publicaciones en función de los años. Para ello se consideraron distintas etapas del desarrollo de la restauración ecológica en Argentina mencionadas por Zuleta et al (2015) y de Paz et al (2019): periodo inicial hasta 2004, caracterizado por esfuerzos aislados de restauración; periodo intermedio de 2005 -2010 con mayor participación de investigadores y practicantes en la temática; y el último período de 2011 a la actualidad con grandes avances teórico-prácticos e integración de diferentes grupos.…”

The United Nations Decade on Ecosystem Restoration is both an opportunity and a challenge to contribute to the recovery of degraded ecosystems. The general objective of this work was to provide an overview of studies regarding ecological restoration carried out in the Andean Patagonian Forest region of Argentina. The specific aims were: (1) to quantify the publications on the subject and identify the reporting language, (2) to classify the publications by type of ecosystem and type of research (basic or applied research, passive or active restoration), and (3) to identify principal causes of degradation. By means of the Scopus database, a search was made for publications with the descriptors "Restau* + Argentina" and "Restor* + Argentina". Between 1998 and 2022, 28 publications were registered. Most of the works correspond to basic research and are written in English. The most studied ecosystems were the Austrocedrus chilensis and Nothofagus pumilio forests. Forest fires, invasion of exotic plants and presence of exotic herbivores were the main causes of disturbance. Although there is significant scientific development of the topic, the dissemination of scientific knowledge to stakeholders for environmental management and implementation of projects in the territory is still a pending issue.

“…En Latinoamérica se evidencia un interés creciente en la restauración de ecosistemas boscosos (Meli et al 2019;Schweizer et al 2019). En la Argentina se están llevando a cabo diversos proyectos de RE, especialmente luego de la sanción de la Ley de Presupuestos Mínimos de Protección Ambiental de los Bosques Nativos (Ley 26331) y del establecimiento del Plan Nacional de Restauración de Bosques (Pérez et al 2018;de Paz et al 2019;Kutschker et al 2020). En este contexto, aplicar técnicas modernas para generar mapas detallados que permitan localizar y cuantificar áreas con déficit de bosque es esencial para planificar proyectos de RE más eficientes y eficaces (Macfarlane et al 2016).…”

Evaluación del déficit de bosques de ribera en Tucumán

R��.Los bosques de ribera se encuentran entre los ecosistemas más vulnerables, y para mantener los servicios que brindan se necesita su restauración ecológica. El objetivo principal de nuestro trabajo fue generar un mapa de zonas ribereñas a fin de identificar bosques, áreas transformadas y oportunidades para restaurar estos ecosistemas en Tucumán, Argentina. Comparamos diferentes anchos de zonas de amortiguación (ZdA): según requisitos legales (60 m) y sugerencias científico-técnicas (100 y 250 m). Para explorar la superficie de unidades de producción agrícola (UPA, lotes catastrales) ubicadas en las ZdA analizamos diferentes regiones agroecológicas y porcentajes de superficie ocupada en las UPA. La cobertura del suelo se cartografió a partir de una clasificación supervisada de imágenes Sentinel en Google Earth Engine. Nuestros resultados revelaron que para alcanzar a cubrir los 60 y 250 m de ZdA se necesitaría restaurar entre 40 y 60% de las zonas ribereñas, respectivamente, en su mayoría bajo agricultura. Si se considera una ZdA de 60 m, las riberas se encuentran ocupadas por usos agrícolas y urbanos en 23.5% (1959 ha) en el pedemonte, 50.9% (7784 ha) en la llanura húmeda y 36.8% (3113 ha) en la llanura seca. Nuestros resultados sugieren que se deben realizar diferentes esfuerzos para restaurar de manera eficiente las distintas regiones agroecológicas. La restauración necesaria para cubrir el requisito legal podría ser una meta alcanzable considerando objetivos globales y regionales. La mayoría de las UPA incluyeron menos de 20% de su superficie en una zona ribereña. Sin embargo, se recomienda incorporar abordajes socio-ecológicos en los proyectos de restauración, a fin de conocer las visiones de los productores, proponer compensaciones y evitar restricciones que afecten la producción agrícola local. El mapeo realizado será una herramienta valiosa para implementar proyectos de restauración en un área prioritaria de la Argentina.[Palabras clave: vegetación de ribera, restauración ecológica, agricultura, gestión ambiental, zona de amortiguación] A��. Evaluation of the riparian forest deficit in Tucumán. Riparian forests are among the most vulnerable ecosystems. Ecological restoration is needed to maintain the ecosystem services they provide. The main goal of the present study was to generate a map of riparian zones identifying forest and transformed areas as a base for their restoration in Tucumán, Argentina. We compared different buffers width: one according to legal requirement (60 m) and two scientific-technical suggestions (100 and 250 m). To explore the occupation of the agronomic production units (cadastral units) by the buffers, we analyzed riparian land cover among different agro-ecological regions and the percentage of production units area affected. Land cover maps were performed through a supervised classification of Sentinel in Google Earth Engine. Our results revealed that between a 40 and 60 percent of the riparian zones, mainly covered by agriculture, need to be restored to reach the 60 a...

“…Also, an increase in extend and severity is expected, driven by multiple causes such as fuel wood accumulation as a consequence of fire suppression and fuel type changes promoted by the introduction and spread of fire‐prone exotic conifers and other productive activities (Veblen et al, 2011). Under this situation, there is an increasing interest to promote and develop ecological restoration following fires, with efforts in setting the most appropriate ecological restoration strategy for each situation (de Paz et al, 2019; Souza‐Alonso et al, 2022). The first step to select the most appropriate ecological restoration strategy is to know the initial stage of the ecosystem after the disturbance and visualize the possible future scenarios considering ecological, social and economical aspects (Souza‐Alonso et al, 2022).…”

A change in fire regimes is occurring worldwide, affecting post‐fire succession. Under this context, there is an increasing need to prioritize restoration areas and focus on their particular goals. To assess the emergent understorey represents the first approximation of post‐fire re‐vegetation, necessary to establish appropriate restoration guidelines. In this study, we aimed to assess the initial post‐fire response in a mid to high‐severity fire in the Andean‐Patagonian forests. We (1) compared plant community structure among fire severities, (2) evaluated the response of plant community structure to the interaction between fire severity and forest type, (3) compared plant composition among fire severity‐forest type categories and (4) evaluated woody species regeneration after fire. We found that the vegetation cover of the lower stratum began to recover early after the fire and to a greater extent in mid than in high severity, whereas the upper stratum was incipient in the mid and nil in high severity. Native species predominated in burned and unburned plots, although they were less in the burned plots. Among the growth form, shrubs and trees were similarly affected by fire, independently of the forest type. Plant community composition varied among most fire severity‐forest type categories. The frequency of woody species regenerated by resprouts and by seeds was lower in burned than unburned plots. These results suggest that although there is an early recovery of vegetation, the high cover of exposed soil and the loss of the upper vegetation stratum may favour erosion and difficult tree establishment. Besides, tree species that only regenerate from seeds will probably not recover naturally. In addition, the presence of exotic species with high invasive risk may need control. Thus, since fire severity and forest type may drive different post‐fire natural recovery scenarios, different restoration actions should be taken to promote resilient systems for the future.
