Thanks to one of the teachers from the 2015 BREEF Teacher Training Workshop, we have some new information on the state of mangroves on Moore’s Island. She and her students did a handful of mangrove surveys near their school. Most of the mangroves sampled were white mangrove (Laguncularia racemosa) or black mangrove (Avicennia germinans). Students found that disease was relatively low in the mangrove patches they sampled with 2-10 leaves showing signs of disease (e.g., lesions). They also noted that the patches with diseased leaves had garbage present, were dry, and were near a development. The lesions are similar in appearance to the lesions we have found on red mangrove, but the color of the lesion is much lighter on white and black mangrove leaves than red mangrove leaves. Based on images alone, it is very hard to say whether the lesions on the black and white mangrove leaves are a result of the same pathogen.
Thanks again to the students and teacher from Moore’s Island for taking part in mangrove surveys!
