“…1 Landscape context of ecological succession on landslides including disturbances that cause landslides, landscape inputs and outputs and interactions of developing soils and plant communities through succession. Modified from Walker et al (1996) weathering and soil infilling (Sidle and Ochiai 2006), impact regional carbon cycles (Stallard 1998;Restrepo et al 2003), reduce vegetative cover (Tang et al 1997) and shape landscape features such as altitudinal tree limits in Chile (Veblen et al 1977). In turn, the landscape context influences light conditions , the amount and impact of precipitation (Larsen and Simon 1993) and the amount and type of atmospheric deposition (McDowell et al 1990).…”

Landslides are excellent illustrations of the dynamic interplay of disturbance and succession. Restoration is difficult on landslide surfaces because of the high degree of spatial and temporal heterogeneity in soil stability and fertility. Principles derived from more than a century of study of ecological succession can guide efforts to reduce chronic surface soil erosion and restore both biodiversity and ecosystem function. Promotion of the recovery of selfsustaining communities on landslides is feasible by stabilization with native ground cover, applications of nutrient amendments, facilitation of dispersal to overcome establishment bottlenecks, emphasis on functionally redundant species and promotion of connectivity with the adjacent landscape. Arrested succession through resource dominance by a single species can be beneficial if that species also reduces persistent erosion, yet the tradeoff is often reduced biodiversity. Restoration efforts can be streamlined by using techniques that promote successional processes.

“…9 Forest harvesting in the Canadian boreal forests may also change DOM quality in streams as vegetation and hydrological ow paths become disturbed across the landscape. For example, using forestry machinery can change landscape slope and runoff pathway density, 66,67 which may increase oxidized lignin content and the abundance of nitrogenated and sulfurized DOM in receiving streams as disturbance increases. These differences in DOM composition across seasons may also impact inorganic contaminant transport.…”

“…Trees can acclimate to their general wind environment by, for example, altering compression wood formation (Wohlgemuth et al 2022), crown geometry (Wade and Hewson 1979), and stem taper (Brüchert and Gardiner 2006) to better match their local wind environment. However, if the local wind environment changes suddenly, for example due to harvesting, trees may not have time to acclimate to the new wind environment, potentially increasing wind-related tree mortality (Tang et al 1997;Zeng et al 2004).…”

“…This suggests that increasing gap shape complexity does not increase the extent of wind disturbance, but rather results in a higher number of small disturbance patches. In a forest landscape with high gap shape complexity, a higher number of stands are located at the wind sensitive gap edge compared to a landscape with simple shaped canopy gaps, potentially resulting in increased disturbance severity with increasing gap edge density (Lohmander and Helles 1987;Tang et al 1997). Similarly, increasing gap shape complexity may also indicate increased forest fragmentation (Slattery and Fenner 2021), suggesting an increased number of disturbance patches due to an increased number of separate forest patches.…”

“…Disturbance events consist of environmental forcing interacting with ecosystem properties (Peters et al 2011). In the context of wind disturbance, harvesting alters the ecosystem properties by increasing the susceptibility of stands adjacent to the harvest gaps to wind disturbances by predisposing unacclimated trees to high wind loads (Suvanto et al 2016;Tang et al 1997). The larger the harvest gaps, the greater the wind load during a storm event because larger gaps allow for higher wind speeds and thus higher disturbance severities (Dupont and Brunet 2008;Panferov and Sogachev 2008) landscapes with large harvest gaps may exhibit high clustering of wind disturbance patches.…”

Context Wind is an important disturbance in circumboreal forests, and its frequency and severity may change with climate change, highlighting the need to understand the drivers of wind disturbance. Currently, how landscape configuration drives wind disturbance is poorly understood. Objectives We investigated whether and how landscape configuration is related to the extent and spatial pattern of wind disturbance, and how these relationships vary between windstorms and thunderstorms. Methods We used salvage logging data after 16 storms that occurred in Finland between 2011 and 2021. We placed a total of 301 landscapes, each encompassing an area of 8024 ha, within the storm tracks and used regression models to test how wind disturbance extent, disturbance patch size, number of disturbance patches, and disturbance patch clustering were related to landscape configuration and storm characteristics. Results Increasing mean gap size and edge density, including permanent openings (e.g., lakes) and recent harvest gaps, increased disturbance extent, disturbance patch size, and number of disturbance patches. Conversely, increasing mean harvest gap size decreased disturbance patch clustering. Increasing wind speed had the largest contribution to increasing disturbance extent and number of disturbance patches, and decreasing disturbance patch clustering, with the magnitude of the effect varying between windstorms and thunderstorms. Conclusions The extent and spatial pattern of wind disturbances varied with landscape configuration and storm characteristics. Disturbance patches were larger in landscapes with large canopy gaps, resulting in a greater disturbance extent, exacerbated by increasing wind speed and thunderstorm development.
