Summary: Anthropogenic climate change increases the frequency and severity of wildfires in the boreal region, affecting post-fire vegetation responses. Young forests show higher climate sensitivity compared to mature forests, highlighting the importance of studying post-fire recovery in changing climate conditions.

Summary: Australia experienced severe drought, high temperatures, and massive forest fires in 2019 and early 2020. However, the eucalyptus trees showed strong fire resilience, and the understory vegetation quickly recovered in 2020. Using multiple sensors, this study analyzed the impacts of fire and climate on forest areas in Australia and found that the forests experienced significant losses in 2019 but showed large gains in 2020 due to the high resilience of trees and favorable conditions. The results highlight the potential of monitoring and assessing post-fire recovery using remote sensing.

Summary: The study found that in boreal peatlands, despite the ongoing decline of black spruce (the dominant species), NDVI trends were predominantly positive. The magnitude of these trends correlated positively with black spruce growth trends, but was also governed to a large extent by tree mortality and recruitment.

Summary: This study analyzed the resilience of Europe's forests using satellite-based indicators and found that, on average, forests in Europe recover to pre-disturbance levels within 30 years. The resilience of Europe's forests to disturbances is high, with recovery being over 10 times faster than disturbance on most of the forest area. However, 14% of Europe's forests have low or critical resilience, with disturbances occurring as fast or faster than forest canopy can recover.

Summary: European forests have shown a slight increase in tree canopy extent over the past two decades, with the most significant growth observed in Eastern Europe, Southern Europe, and the British Isles. However, after 2016, there has been a decline in tree canopy extent in Europe. Some regions, particularly Fennoscandia, have experienced a reduction in tree canopy extent between 2001 and 2021. Additionally, the continental extent of tall tree canopy forests has decreased during this period.

Summary: The Earth's climate has been rapidly warming since the beginning of the industrial era, leading to the need for terrestrial organisms to adapt. Migration is an effective method for survival and growth, but the rate at which tree species migrate due to climate change remains uncertain. This study used radiocarbon-dated macrofossils to examine the past migration velocity of jack pine and black spruce in North American boreal forest. The results showed that the migration velocity of jack pine varied based on different climatic conditions, while black spruce migrated at a faster rate.

Summary: This study utilized high spatial and spectral resolution AVIRIS-NG hyperspectral data to generate more accurate fire fuel maps compared to those generated using low resolution Landsat 8 data. The accuracy was significantly higher and more vegetation classes were identified, demonstrating the value of AVIRIS-NG for providing decision-support information to fire managers.

Summary: Energy exploration leads to habitat fragmentation worldwide, particularly in the boreal forests of Alberta, Canada where seismic lines are significant sources of forest fragmentation. Reforestation efforts have been focused on these lines, but they are expensive and vulnerable to wildfires. However, a study found that even burnt seismic lines showed higher tree regeneration density compared to adjacent forests.

Summary: The largest forest wildfire in Swedish modern history burnt 14,000 ha of Boreal forest in the Vastmanland County during the summer of 2014. The impacts of this wildfire on the hydrological regime were assessed over the three years following the event, showing changes in snow season duration and timing, streamflow behavior, and catchment response. The study demonstrates the usefulness of combining flow signatures and remote sensing products to detect changes in catchment hydrology.

Summary: Climate change is expected to increase wildfire activity in boreal ecosystems, threatening the carbon stocks of these forests. Understanding fire regimes and their relationship with climate and vegetation is crucial for anticipating the impact of climate change. However, the lack of long-term knowledge hinders this understanding in Fennoscandia.

Summary: The study utilized SIF to estimate post-fire vegetation recovery, revealing that 20 years is insufficient for recovery with a significant increasing trend in SIF within burned areas during the first 6 to 10 years after wildfires. Additionally, differences in SIF values were found within and outside burned areas at different stages of vegetation recovery.

Summary: Post-harvest recovery of biodiversity is a key goal in modern forestry. This study investigated the response of rove beetles to different levels of retention harvest in a boreal mixedwood forest in western Canada. The results showed that even modest levels of forest retention can facilitate the recovery of rove beetle assemblages in managed landscapes within the first 16 years post-harvest.

Summary: Recent studies have explored the long-term dynamics of forest disturbance detection and recovery using remote sensing images. However, existing automated change-detection algorithms face challenges in mapping consecutive multiple disturbance agents. Additionally, there is uncertainty about the effects of burn severity, biological-legacy management, and active forest restoration on post-disturbance vegetation dynamics. This study proposes a modified disturbance index to detect fire and forest logging using normalized tasseled-cap components, and to distinguish the recovery patterns of post-fire forests considering the cumulative effect of fire, post-fire logging, and recovery approaches.

Summary: The study found that climate fluctuations had the most significant impact on forest burned areas, while the effects of Euro-Canadian settlement were relatively weak. In fire-prone climate conditions, burned areas were maximized regardless of fluctuations in the Euro-Canadian population.

Summary: This study assessed the impacts of climate change on black spruce and jack pine growth in boreal forests of North America. Climate factors such as vapor pressure deficit and temperature were found to have positive effects on tree growth, although the effects varied depending on site conditions and climate scenarios. Future projected increases in tree height were relatively small and may not be enough to offset potential increases in disturbances like forest fires.

Summary: The increase in frequency, intensity, and duration of drought events affects forested ecosystems by causing trees to adjust stomatal conductance to maximize the trade-off between carbon gains and water losses. This study found that a decline in growth rates of black spruce and jack pine in an exceptionally dry period from 1988 to 1992 was related to physiological adjustments of trees to drought. Isotopic signals were linked to climate moisture index, vapor pressure deficit, and annual snowfall amount, impacting tree growth and physiological responses.

Summary: Studying post-disturbance recovery is crucial for predicting forest ecosystem resistance and resilience. However, research on recovery after natural disturbances is relatively scarce, with a strong focus on forest harvesting. Long-term research, chronosequences, and consecutive disturbance studies are important for establishing sustainable forest management strategies.
