In Florida, conservationists are currently trying to contain an infestation of an Asian mangrove species, Lumnitzera racemose, that spread from a renowned botanical garden in Miami. While most terrestrial plants use whats called a taproot to burrow deep into the ground for support, several mangrove species rely on sprawling cable roots that stay within a few centimeters of the soils surface for stability and access to oxygen. /Tabs /S In the 1950s, coastal villages in the Indo-Pacific had an average of 5 miles of mangrove forest between themselves and the ocean. /F1 27 0 R >> /StructParents 9 /GS7 46 0 R /Type /Group >> /CropBox [0 0 612 792] The roots undulate away from the trunk in curving S shapes. 2017-11-07T16:38:10Z In 1918, their most northern limit was Miami.
