Do you agree with this statement? why or why not? the main idea of this article specifies that on the preservation of the florida everglades and its phosphorus redistribution mechanisms. the roles of these mechanisms are said to transfer phosphorus, a limiting nutrient, to the tree islands of the everglades which allows for tree island size and elevation to increase. however, with human impact on the hydrology of the everglades, has this caused for an instability in the distribution of phosphorus towards tree islands. this can greatly hinder the growth and development of wetland vegetation and the surrounding vegetation in the everglades. because of human impact on the hydrology of the everglades have we seen a negative turn on tree island density. according to the article, "the number of small islands (< 3.2 ha) decreased by 98%", emphasizing that with the instability in the hydrology of the everglades, the ecosystem as a whole is experiencing huge changes. to add to this, the loss of these tree islands have also resulted in the decrease of landscape complexity. tree islands are by far a necessity towards the balance of the everglades. it is stated in the article that, "soil phosphorus levels on tree islands are up to 100 times higher than those in the surrounding marshes and sloughs, creating biogeochemical hotspots.", referencing that tree islands are generally a buffer zone for nutrients to be dispensed across the everglades. if you think about it, you can imagine that tree islands are like the bloodline of the everglades as it absorbs and redistributes the phosphorus across the ecosystem. a possible way to expand tree islands, besides limiting the human impact of the everglades, would be something that mother nature does on its own. according to the article, " greater canopy leaf area and height may redistribute nutrients to tree islands, primarily through evapotranspirational pumping of groundwater and higher rates of dry ", which makes sense when you consider that plants require water to survive and that the water cycle provides rain that can contain phosphorus in one form. with the ability to reach the sun's rays and closer access to rainfall, an increase in the height of the leaves can be a key benefactor into redeveloping and expanding more tree islands. i believe, after reading this article, the best way to redevelop the everglades would push for a stricter preservation plan. i was convinced by this view through this statement, which specifies, " the current restoration plan for the everglades emphasizes the restoration of historic hydrologic flow and periodicity and a reduction of anthropogenic sources of p. restoring traditional hydrologic flows should reduce the extended flooding or drying of tree islands." from what i understand, mother nature needs to do its course but we as humans must limit ours in the location of the everglades.
