“…In the Cathedral Peak area, wetlands representing potential fossil pollen archives are present across a range of altitudes (e.g. Finch et al 2021;Lodder et al 2018), from the montane to subalpine to alpine (e.g., this study), although the depth and organic content of these sites is variable.…”

“…Most of the Mont-Aux-Sources LTSER area is a high-elevation grassland ecosystem (Carbutt 2019; Finch et al 2022). The rangeland is under traditional leadership governance (Basotho, Batlokoa, and Bakoena Royal Houses and the Inyongama Tribal Trust) and is used seasonally for communal grazing by domestic livestock.…”

“…In South Africa, there is evidence of bracken fern encroachment in the Drakensberg Mountains. Although it is not clear how bracken fern was introduced in the Drakensberg, Finch, Hill [ 5 ] noted that archeological evidence suggests that the existence of bracken fern in the Drakensberg montane grasslands can be traced back to as far as 1840 CE. Due to its vigorous growth and dense canopy, the fern has negative impacts on agricultural productivity [ 6 ], animal and human health [ 7 ], forestry and recreational potential [ 8 ], leading to huge economic losses.…”

Characterizing bracken fern phenological cycle using time series data derived from Sentinel-2 satellite sensor

Bracken fern is an invasive plant that has caused serious disturbances in many ecosystems due to its ability to encroach into new areas swiftly. Adequate knowledge of the phenological cycle of bracken fern is required to serve as an important tool in formulating management plans to control the spread of the fern. This study aimed to characterize the phenological cycle of bracken fern using NDVI and EVI2 time series data derived from Sentinel-2 sensor. The TIMESAT program was used for removing low quality data values, model fitting and for extracting bracken fern phenological metrics. The Sentinel-2 satellite-derived phenological metrics were compared with the corresponding bracken fern phenological events observed on the ground. Findings from our study revealed that bracken fern phenological metrics estimated from satellite data were in close agreement with ground observed phenological events with R2 values ranging from 0.53–0.85 (p < 0.05). Although they are comparable, our study shows that NDVI and EVI2 differ in their ability to track the phenological cycle of bracken fern. Overall, EVI2 performed better in estimating bracken fern phenological metrics as it related more to ground observed phenological events compared to NDVI. The key phenological metrics extracted in this study are critical for improving the precision in the controlling of the spread of bracken fern as well as in implementing active protection strategies against the invasion of highly susceptible rangelands.
