“…For effective land management and biodiversity conservation, it is essential to understand certain landscapes as mosaics of dynamic regimes rather than simplistic static cover types [7][8][9]. Temporarily-inundated wetlands belong to such category and require special approaches to assess their spatio-temporal dynamics.…”

“…Coupled with ground data like gauging stations, S1-omnibus and Sentinel-1 time series can be used to improve hydrological models [27]. Wetland managers can easily interpret the patterns of change and use them to locate and delineate areas of high rates of change, which are prone to have a high ecological value [8,9]. Incorporating a temporal variable into the LULC classification procedures may allow the separation of land cover categories that, to this date, have proven difficult.…”

“…Examples of DCT in the context of wetlands would be seasonally-inundated floodplains and inland valleys, inter-tidal flats, temporal water bodies and waterways, fields of rice and reeds when harvested or slow regrowth of some vegetation covers after flooding or harvesting events. Many of these DCT often give rise to unique species assemblages and temporal shifting of species distributions and compositions [8,9]. In turn, this may also affect other ecosystem functions through water and nutrient cycling.…”

Short-Term Change Detection in Wetlands Using Sentinel-1 Time Series

Automated monitoring systems that can capture wetlands' high spatial and temporal variability are essential for their management. SAR-based change detection approaches offer a great opportunity to enhance our understanding of complex and dynamic ecosystems. We test a recently-developed time series change detection approach (S1-omnibus) using Sentinel-1 imagery of two wetlands with different ecological characteristics; a seasonal isolated wetland in southern Spain and a coastal wetland in the south of France. We test the S1-omnibus method against a commonly-used pairwise comparison of consecutive images to demonstrate its advantages. Additionally, we compare it with a pairwise change detection method using a subset of consecutive Landsat images for the same period of time. The results show how S1-omnibus is capable of capturing in space and time changes produced by water surface dynamics, as well as by agricultural practices, whether they are sudden changes, as well as gradual. S1-omnibus is capable of detecting a wider array of short-term changes than when using consecutive pairs of Sentinel-1 images. When compared to the Landsat-based change detection method, both show an overall good agreement, although certain landscape changes are detected only by either the Landsat-based or the S1-omnibus method. The S1-omnibus method shows a great potential for an automated monitoring of short time changes and accurate delineation of areas of high variability and of slow and gradual changes.

“…Resilience of managed forest ecosystems can be enhanced by management actions that maintain the complexity of forest structure and dynamics from the stand to landscape scale [122,123]. Natural disturbances, when they occur within the natural range of variation for a particular ecosystem, serve to increase forest complexity by creating stand and landscape scale heterogeneity and can thus promote forest resilience.…”

Abstract:The mountain pine beetle (Dendroctonus ponderosae Hopkins) (MPB) has infested and killed millions of hectares of lodgepole pine (Pinus contorta var. latifolia Engelm) forests in British Columbia, Canada, over the past decade. It is now spreading out of its native range into the Canadian boreal forest, with unknown social, economic and ecological consequences. This review explores the ramifications of the MPB epidemic with respect to mid-term timber supply, forest growth, structure and composition, vegetation diversity, forest fire, climate change, and ecosystem resilience. Research confirms that, in British Columbia, all of these variables are more significantly impacted when salvage logging is used as management response to the outbreak. We conclude that appropriate management in response to MPB is essential to ensuring ecologically resilient future forests and reliable mid-term timber supplies for affected human communities. We highlight knowledge gaps and avenues for research to advance our understanding in support of sustainable post-disturbance forest management policies in British Columbia and elsewhere.

“…Prell et al 2007). The paper also champions the notion of establishing "envelopes" of probable future states (Parrott and Meyer 2012) in which decision-making and policies are designed to maintain the landscape within a desired range or envelope. Thackway et al (2013) use modeling to examine NRM decision-making for two case studies involving management of fire and soil erosion.…”

This is the introduction to the Ecology and Society special feature on "Applying Landscape Science to Natural Resource Management". Primarily drawing upon examples from Australia, the nine papers in the feature illustrate how landscape science seeks to integrate information from diverse sources to generate management solutions for implementation by individual land managers, communities, and governments at different levels. This introduction refers to the genesis of the feature, briefly outlines the nature and content of landscape science, and then summarizes key features of the nine papers. These are organized into two sections: one deals with inputs from human agents in the landscape, and one with the development of models enabling different management scenarios and environmental changes to be envisaged, understood, and applied to policy development
