Lately I have noticed the consistent march of mangrove seedpods in the water off the dock–more than normal. These king tides reach higher up into the mangroves, where the pods detach and begin to float vertically in the water, the tides shuttling them to far away places. A soaking of the pod softens the outside shell and it begins to peels away, allowing the seedpod to germinate. The vertical position is by design so when the tide drops the seeds settle upright in the soft muds along the banks, providing the ideal location to spread. I cannot help but think how closely these pods remind me of the seeds of Phragmites, releasing at once, wondering if these mangrove pods are also carrying the alien contagion.
