Peatland restoration projects are being employed worldwide as a form of climate change mitigation due to their potential for long-term carbon sequestration. Monitoring these environments (e.g., cover keystone species) is therefore essential evaluate success. However, existing studies have rarely examined peatland vegetation at fine scales its strong spatial heterogeneity and seasonal canopy development. The present study collected centimetre-scale multispectral Uncrewed Aerial Vehicle (UAV)...
Small unmanned aerial systems (UAS) have allowed the mapping of vegetation at very high spatial resolution, but a lack standardisation has led to uncertainties regarding data quality. For reflectance measurements and indices (Vis) be comparable between sites over time, careful flight planning robust radiometric calibration procedures are required. Two sources uncertainty that received little attention until recently illumination geometry effect flying height. This study developed methods...
Plant phenology is an important driver of inter-annual variability in peatland carbon uptake. However, the use traditional datasets (e.g., manual surveys, satellite remote sensing) to quantify this link hampered by their limited spatial and temporal coverage. This study examined cameras (phenocams) uncrewed aerial vehicles (UAVs) for monitoring a Scottish temperate peatland. Data were collected at site over multiple growing seasons using UAV platform fitted with multispectral Parrot Sequoia...
Boreal peatlands are an important sink for carbon. Carbon uptake and emission controlled by abiotic factors as well vegetation composition plant phenology. Plant functional types (PFT) have distinct phenological trajectories respond differently to environmental controls which results in seasonal variations their relative contribution peatland net CO2 ecosystem exchange (NEE). However, detailed knowledge on the separate responses of PFT-specific production respiration fluxes daily...
Abstract. Arctic tundra ecosystems are currently facing amplified rates of climate warming. Since these store significant amounts soil organic carbon, which can be mineralized to carbon dioxide (CO2) and methane (CH4), rising temperatures may cause increasing greenhouse gas fluxes the atmosphere. To understand how net ecosystem exchange (NEE) CO2 will respond changing climatic environmental conditions, it is necessary individual responses processes contributing NEE. Therefore, this study...
Abstract. Arctic tundra ecosystems are currently facing rates of amplified climate change. This is critical as these store significant amounts carbon in their soils, which can be mineralized to CO2 and CH4 released the atmosphere. To understand how net ecosystem exchange (NEE) fluxes will react changing climatic conditions, it necessary individual responses physiological processes contributing NEE. Therefore, this study aimed: (i) partition NEE at soil-plant-atmosphere interface an arctic...
Northern peatlands are recognised as important long-term carbon sinks. However, measurements from a number of peatland sites reveal large amount interannual variability in their net dioxide (CO2) balance. Differences both weather conditions and plant phenology (i.e. the seasonal development vegetation canopy) between years thought to be key here. Timing growing season start, end, length) regulates period over which can actively photosynthesise. Hence, longer is often related increased CO2...
<p>Peatlands are terrestrial carbon sinks of global significance, storing an estimated one-third soil carbon. Net Ecosystem Exchange (NEE) dioxide (CO<sub>2</sub>) can however vary substantially on seasonal and inter-annual timescales, with some peatlands switching from a sink to source CO<sub>2</sub>. Complex sometimes competing processes, such as meteorology phenology, regulate peatland’s net strength....
<p>Peatland ecosystems are historical carbon sinks of global importance, whose management and restoration becoming an increasingly popular approach to reach climate change targets via natural capital. However, the Net Ecosystem Exchange (NEE) dioxide (CO<sub>2</sub>) can exhibit substantial variability on seasonal inter-annual timescales, with some peatlands shifting from being a sink source...
