FOR MICHELLE'S NATURE NOTES and NATURE FOOTSTEPS-WATER (Thank you!)
Visiting the Everglades during the dry and then the beginning of the wet season provided a quick and obvious lesson on the importance of water to the health of our environment. On our most recent visit, we noted one sign reminding us that our planet is seventy-five percent water -- it suggested that this third rock from the sun might better be named "Water" instead of "Earth."
The Everglades is all about water, in seasonal cycles of rain and drought.
The above picture and the next one are from an earlier trip we took by boat. This one is the edge of Lake Okechobee, the major source of water for the Everglades. The next picture is a lock on Lake O.
The information in italics under each of our pictures is taken from National Park Service explanatory signs in the Everglades.
Historically Lake Okechobee overflowed with rain each spring. But today, humans have engineered nature, disrupting the flow that nourishes the Everglades and its wildlife.
The entire Everglades food web has evolved in pure low-nutrient water. Changes in water quality due to nutrient contamination (the introduction of phosphates and nitrates) threaten the natural glades. (Sawgrass, seen above, is a sedge-like plant that grows naturally in low-nutrient water. Stands of cattails seen elsewhere in the park are not natural, they are growing as a result of nutrient contamination.)
Increased public awareness and support offer the hope of restoring natural conditions. Park managers, working with other agencies, are restoring portions of the ecosystem that will help protect this "River of Grass" -- from its headwaters in Lake Okechobee to its exit into the Gulf of Mexico and Florida Bay.
"Here is land, quiet in its tranquil beauty, serving not as the source of water, but the last receiver of it. To its natural abundance, we owe the spectacular plant and animal life that distinguishes this place from all others in this country." President Harry S Truman, dedicating Everglades National Park, December 6, 1947 .
