Let us start by expressing the importance of this article, 20 kilometers from Guaymas and 10 kilometers to the east of San Carlos, in the scenic road we have a coast where you can find the “Estero del Soldado” this area since 2018 is considered ecological conservation zone by the government of Sonora and in 1992 was designed as a priority national wetland zone by the Conservation International North American Wetland Conservation Council
According to the Information Sheet of the Wetlands of Ramsar despite being a small lagoon, it is home to a large number of animals and plants. It has an initial record of 408 species: 121 marine invertebrates, 80 fish, 75 birds, 11 reptiles, 9 amphibians, 9 mammals; and 103 plants.
It is also mentioned that El Soldado estuary is temporary habitat for the growth of three species of crustaceans in the population of the Gulf of California. Two shrimp: blue, litopenaeus stylirostris, and brown, farfantepenaeus californiensis, and one of the crab known as blue or cuata, callinectes arcuatus.
The Soldado Estuary also is an habitat for species like, achirus mazatlanus,short anchovy, large flake anchovy, mackerel, bass, yellowmouth croaker, horse mackerel fish, not only fishes but birds, feeding, nesting and a place for them to rest and as a refuge site.
Mangroves besides working for protection and reproduction animal purposes also help to filter water absorb excess nutrients and trap sediments, helping to increase the clarity and quality of waters, they are called the “Lungs of the sea”.
In the Soldado estuary you can find black mangrove, white mangrove and red mangrove. Avicennia germinans (black mangrove) is the most abundant in the area, in the inner dense part, adjacent to the body of water is formed by Rhizophora mangle (red mangrove). The Red Mangrove, also called the ‘walking tree’ since is the tallest of all the mangroves, it can be as tall as 80 feet and are usually where conditions are harshest finally, the Laguncularia racemosa (white mangrove) can be usually found in shallow waters next to red mangrove.
Furthermore the functions of the mangroves we mentioned above, they also bring environmental security; extended mangrove areas can even reduce the damage and impact caused by tsunamis by taking the first brunt of the impact and also helping by dissipate the energy of the waves and winds.
