CBH (circumference at breast height), height and species data were collected to characterize vegetation structure and above-ground biomass (AGB) at 17 plots with a total of 3090 measured individuals. Significant relationships between the linear \u03c3\u00b0 in VH (vertical transmit, horizontal receive) cross-polarization produced r2 values of 0.63 for the average height, 0.53 for the DBH, 0.46 for the basal area (BA) and 0.52 for the AGB. Using co-polarized HH (horizontal transmit, horizontal receive) and VV (vertical transmit, vertical receive), r2 values increased to 0.81, 0.79, 0.67 and 0.79, respectively. Vegetation attribute maps of average canopy height, DBH and AGB were generated for the study area. We conclude that multi-polarized Radarsat-2 images were adequate for characterization of vegetation attributes in areas of mangrove regeneration.<\/jats:p>","DOI":"10.3390\/rs71215873","type":"journal-article","created":{"date-parts":[[2015,12,17]],"date-time":"2015-12-17T10:47:37Z","timestamp":1450349257000},"page":"17097-17112","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["Radarsat-2 Backscattering for the Modeling of Biophysical Parameters of Regenerating Mangrove Forests"],"prefix":"10.3390","volume":"7","author":[{"given":"Michele","family":"Cougo","sequence":"first","affiliation":[{"name":"Geoscience Institute, Universidade Federal do Par\u00e1, Cidade Universit\u00e1ria, P.O.
