We all live in a watershed! 10/15/2010 Blog Action Day topic is Water
North-central Florida has been blessed with fantastic and seemingly endless crystal-clear springs. The Floridan aquifer is close to the surface in this area and water pressure caused by water percolating into the limestone formations already filled with water flows to the surface. Some springs discharge more than 65 million gallons of water per day. Several state parks have been located to include these springs.

|Mangrove swamps provide critical habitat for fish, invertebrates, birds, and mammals. |
The red mangrove (Rhizophora mangle) is one of three mangroves, but only one the one with stilts for roots.
We featured mangroves in a this posting.

Here's another example of the critical role mangroves play. The cold snap that occurred in January this year caused the water temperatures to drop so low that massive fish kills took place. Snook, a favorite of fisherman, were killed in especially high numbers. The species is adapted to events like this, however, and the normal response is an especially high spawn in the spring so that the population can regain stability. But because we have lost so much of our mangrove shoreline, the high spawn numbers will not be fruitful. The baby snook need the protection of mangrove roots. The mangroves provide a virtual nursery for them. Without the mangrove nursery areas, the spawn cannot survive in any significant numbers. Here's a link to an interesting site supported by a sporting group, fly fisherman. Good discussion and illustration of mangrove importance.
