Symptomatic swamp bay were observed in 322 tree islands and along ditches, canals, and roads within the survey area.
Although the present data were from a relatively uniform subtropical habitat and another host species, swamp bay, they may provide a better estimate of how quickly laurel wilt can spread in the absence of anthropogenic movement.
In 2013, tree islands with at least 1 symptomatic swamp bay had a median canopy damage of 5.
Within the current range of occupancy, 76% of the tree islands known to include swamp bay were not yet symptomatic, suggesting that laurel wilt will cause additional mortality.
An abrupt loss of tree island canopy where swamp bay is an important component could reduce peat accretion rates (Cahoon et al.
