Abstract

Aircraft L-band VV-, HH-, and VH-polarizations were examined as tools for monitoring burn recovery in a coastal marsh. Significant relationships wereobserved between time-since-burn (difference between burn and image collection dates; 550-900 days after burn) and returns I elated to all polarizations. As marsh burn recovery progressed, VV returns decreased while HH and VH returns increased. Radar returns extracted from control sites adjacent toeach burn-simulated nonburn marsh and were not individually or in combination significantly related to the time-since-burn. Normalized by the controldata, VH-polarization explained up to 83% of the total variations. Overall, the L-band multipolarization radars estimated time-since-burn within +/-59 to +/-92 days.
