Structural Characteristics of the Tallest Mangrove Forests of the American Continent: A Comparison of Ground-Based, Drone and Radar Measurements

Abstract: The Panama Bight eco-region along the Pacific coast of central and South America is considered to have one of the best-preserved mangrove ecosystems in the American continent. The regional climate, with rainfall easily reaching 5–8 m every year and weak wind conditions, contribute to the exceptionally tall mangroves along the southern Colombian and northern Ecuadorian Pacific coasts (Nariño Department and Esmeraldas Province areas). Here we evaluate the use of different methods (ground-based measurements, dron… Show more

“…However, this error is still much smaller than the RMSE obtained by Castellanos-Galindo et.al. 35 , who calculated the height of mangrove trees on the northern coast of the Nariño Department of the Colombian Pacific coast, using a UAV. The R Square value they obtained was only 0.06.…”

“…[ 74 ], and [ 1 ], which indicate those locations with exceptionally high mangrove AGB presence. However, it's worth noting that for these locations, the training samples [ 27 , 28 , 32 ] that informed the selected model span different dates and places over roughly a 12-year period ( Table 1 and Table SM2 ). This demonstrates that both older and more recent data exhibit notably high AGB values, which is evident in the prediction model.…”

“…(1), Boundary filters for ROI and date were used ( Table 2 ). (2), The height records of mangroves in the CPC were reviewed in the literature and reports of the tallest trees for the CPC were found; this allowed for establishing the limiting heights to apply masking of elevation values in the range of −2 to 60 m height in the images within the ROI, in order to decrease the possible noise introduced by elevation outliers [ 1 , 32 ]. (3), Finally a 3-band composite was performed ( Fig.…”

“…The environmental conditions and poor accessibility have contributed to keeping the remaining mangroves mostly undisturbed across large swaths of the Pacific coast. This condition has allowed the development of some of the tallest mangroves forests in South America, with canopies reaching 54 meters (Simard et al, 2019a) and trees measured in situ reaching 57 meters (Castellanos-Galindo et al, 2021a).…”
