Spectral Bands

Mangroves have significant social, economic, environmental, and ecological values but they are under threat due to human activities. An accurate map of mangrove species distribution is required to effectively conserve mangrove ecosystem. This study evaluates the synergy of WorldView-3 (WV-3) spectral bands and high return density LiDAR-derived elevation metrics for classifying seven species in mangrove habitat in Mai Po Nature Reserve in Hong Kong, China. A recursive feature elimination algorithm was carried out to identify important spectral bands and LiDAR (Airborne Light Detection and Ranging) metrics whilst appropriate spatial resolution for pixel-based classification was investigated for discriminating different mangrove species. Two classifiers, support vector machine (SVM) and random forest (RF) were compared. The results indicated that the combination of 2 m resolution WV-3 and LiDAR data yielded the best overall accuracy of 0.88 by SVM classifier comparing with WV-3 (0.72) and LiDAR (0.79). Important features were identified as green (510–581 nm), red edge (705–745 nm), red (630–690 nm), yellow (585–625 nm), NIR (770–895 nm) bands of WV-3, and LiDAR metrics relevant to canopy height (e.g., canopy height model), canopy shape (e.g., canopy relief ratio), and the variation of height (e.g., variation and standard deviation of height). LiDAR features contributed more information than spectral features. The significance of this study is that a mangrove species distribution map with satisfactory accuracy can be acquired by the proposed classification scheme. Meanwhile, with LiDAR data, vertical stratification of mangrove forests in Mai Po was firstly mapped, which is significant to bio-parameter estimation and ecosystem service evaluation in future studies.

Mean Sea Level

The technical problems of estimating the topographic height of a mangrove species or community are discussed. Transects normal to the seaward mangrove face were taken around the coast of Australia. They confirm that a stable margin will be approximately at mean sea level but that erosion, accretion or other disturbance may cause variation of the order of �1 m. Studies in four species-rich rivers in north Queensland show that (i) there are marked distributional differences with respect to topographic height between long and short river estuaries, these differences being attributable to different tidal patterns; and (ii) there appear to be two mangrove types: the frontal species are tolerant of inundation, poorly adapted to emersion, whereas the upstream species behave as dry-land plants tolerant of only limited inundation. The topographic height range of individual plants of a single species may be almost 4 m, so that observations on individual plants are of little value.
