- Abstract
Freeze events limit the global geographic range of the tropical mangrove ecosystem. Evidence suggests that with warmer winter temperatures in the Northern Hemisphere that mangroves are increasing their range to higher latitudes: this is especially apparent in the northern Gulf of Mexico. Of the three species of mangroves live in estuarine areas of the Gulf of Mexico, white mangrove (Laguncularia racemosa) is considered the least freeze tolerant and therefore is the most range limited in latitude; however, this species is also the least understood in terms of its freeze tolerance. In this study, we look at the role that microclimate plays in determining freeze damage in white mangrove due to a cold weather event in January 2022 when temperatures reached -- 2 C for several hours in the Tampa Bay region. We compare freeze damage to the three other species mangroves and a mangrove associate. We conclude that microclimate plays a role in damage of trees, but that the freeze event resulted in leaf but not total plant mortality. Most individuals of white mangrove recovered within a matter of months.
