Geographic distribution of black mangrove (Avicennia germinans) in coastal Louisiana in 2009
June 5, 2020
Black mangrove (Avicennia germinans (L.) L.) has historically occurred along the Louisiana coast in saline wetland habitats, but its distribution has been sparse. Mangroves are tropical to semi-tropical species and their distribution is limited by freezing temperatures. Black mangrove distribution and abundance has increased and decreased in the coastal zone of Louisiana according to freeze frequency and duration and concomitant freeze damage and dieback or lack thereof. In 2009, a fixed wing aircraft was used to conduct an aerial cruise census of the entire coastal area of Louisiana to document and map the total distribution of mangroves in the state.

Frequency of extreme freeze events controls the distribution and structure of black mangroves (Avicennia germinans) near their northern range limit in coastal Louisiana
AimClimate change is expected to result in the tropicalization of coastal wetlands in the northern Gulf of Mexico, as warming winters allow tropical mangrove forests to expand their distribution poleward at the expense of temperate salt marshes. Data limitations near mangrove range limits have hindered understanding of the effects of winter temperature extremes on mangrove distribution...
