Sand Dunes - Amazing Structures Providing Shelter & Food |
|
Cozumel is known for its miles and miles of pristine beaches and coastal areas. And all along the island's shoreline there are sand dunes piled up behind these beautiful beaches. As visitors walk along the water's edge and dig their toes into the soft sand, few realize that the health and beauty of the beaches are heavily dependent on the sand dunes just behind them. As more and more research is done on coastal eco-systems, scientists are now beginning to make us fully aware of the critically important role that sand dunes play in our global, coastal eco-systems.
Sand dunes provide a wide range of habitats for a variety of unusual, interesting and adaptive plants that can cope with unstable habitats. Sand dunes form in relatively exposed locations. All over a dune, very specialized plants adapt to the accumulation of sand around them surviving the continual burial of their shoots by sending up very rapid vertical growth. With the help of these plant shoots, small mounds of vegetation and/or tide-washed debris can form and tend to enlarge as the wind-speed drops behind the mound, allowing blowing sand to fall out of the air stream and accumulate which constantly increases the size of a dune. The plants are physiologically adapted to withstand the problems of high salt contents in the air and soil. Sand dunes support a wide variety of colorful flowering plants, including a number of species of orchid.
On the inland side of dunes conditions are less severe, and typical grasslands develop containing a wide range of plant life. When enough humus has accumulated within the grassland sand, this more stabilized soil improves water retention and promotes further plant diversity development. Consequently, sand dune systems are excellent places for biodiversity, partly because they are not very productive for agriculture, and partly because these unstable and stable soil habitats are present in proximity to each other. Many dune areas are protected as nature reserves, and some are parts of larger conservation areas incorporating other coastal co-existing habitats like salt marshes, mud flats, grasslands, scrub and woodland.
All coastal dune ecosystems also support a population of animal species in addition to plant life. Since most animal life requires basic survival elements such as shelter, food and water, it stands to reason that species density in any one area would be dependent on their availability. Small birds, reptiles, crustaceans, and other coastal species commonly call the coastal dunes their home. As the dune system moves from the fore dunes toward the back dunes, with their increased vegetation, the ecosystem becomes more complex, supporting a larger amount of species. Sand dune systems are also very rich in invertebrates including butterflies, moths and burrowing bees and wasps.
The beach is a margin of sand in a dynamic ebb and flow controlled by tides, winds, currents and waves. The critical factor is the presence of a sufficiently large beach plain whose surface dries out between high tides. Off shore shallow sand banks release the initial energy from ocean swells as they break and send secondary waves with low residual energy gently up and down the beach. The dissipative beaches are wide, gently sloping, slow draining and quite firm underfoot because the fine sand particles fit close together. These beaches support a relatively high variety of burrowing organisms. Because of their shallow gradients, these beaches also act as traps for another group of organisms called diatoms. Diatoms survive between sand grains and provide the chief food for bi-valves and other filter feeders.
Recreation is a major land use on sand dune areas. Many dune systems are used extensively by tourists, mostly on foot but also for parking cars and in some cases for driving four-wheel-drive vehicles or motorcycles. Moderate pressure by pedestrians may cause little damage, however, excessive pedestrian use and vehicular use in particular, have caused unacceptable erosion on many dune sites.
Many dune systems also support one or more golf courses. Here much of the original vegetation may be retained in the rough, but the communities of the fairways, and particularly the greens and tees, are often severely modified by mowing, fertilizing and re-seeding. Sand dunes have also been affected in the past by housing developments, industrial development, and waste collection areas on or adjacent to them as well as sand extraction.
What can you do to help protect and conserve Cozumel's sand dunes? |
If you live part time or full time or vacation on the island:
Sign up & participate in ongoing beach cleanup efforts in Cozumel.
Keep your visits to the beaches "green" by not discarding trash. Leave the beach pristine. If you want to go beyond being an environmentally conscious visitor, there are a number of ways you can become proactive in the protection of our sand dunes. Pick up trash as you walk along the shore, and recycle or dispose of it properly. Encourage better behavior by other users; point out regulations and the reasons for them. Report any serious violation you see to the proper authorities.
If you must cross the dune, pick your way between the plants and avoid already-eroded trails and steep approaches. If there is more than one person, select spots where the dune is shallow and spread out; return to the beach by a different route.
Do not build fires on the beach. While dried driftwood makes great campfires, this and other natural debris washed up by the lake help trap sand, and are the only source of nutrients available for plant growth on the dunes. Also, beach campfires leave unsightly scars and pose a fire threat to surrounding vegetation in this dry habitat.
Do not ride all-terrain vehicles on the beach.
Do not disturb water birds, migrating shorebirds, and nesting shorebirds. They are extremely intolerant of visitors and are easily denied nesting habitat by the very presence of recreational beach/dune users.
If you are a golfer, encourage golf course management policies and practices that are sympathetic to the flora and fauna of sand dune systems.
Support legislation for sound management of the world's coastal areas with your government.
Maintaining sandunes is essentional for Cozumel's future.
Thank you for doing your part to protect and conserve Cozumel's sandunes.

What a great relaxing day. We snorkeled the reef, relaxed by the pool, had a few drinks and ate some amazing ceviche (one of the best I tasted on the island). Sherri and her family and staff were so sweet, kind and helpful. It was more like visiting family on vacation. We will be back thank you. D. Jewell - March 2018 ~ Ashley, IN USA

(12/03/2018) - By chance had the entire place to ourselves. Staff made us feel like family, gave us good snorkel tips. The area in which you can snorkel is extensive, pleasantly surprised. Great place to escape the typical Cozumel tourist type stuff. A. Olarte - Google Maps Review ~ Unknown

Sherri, We just returned after a great cruise on the Carnival Holiday. We took a taxi from the cruise pier to Palmar Estate Beach Club and spent about 1/2 a day at your beautiful place. We toured the butterfly sanctuary with your wonderful guide who was informative and very gracious. I also spent quite a bit of time talking to Juan and he was delightful. We relaxed, ate chips and salsa, drank pina coladas and soaked in the sun. What a delightful place you have and a wonderful staff that made our visit great. Thanks and if we get a chance to recommend your place to others we will surely do that.
PS: Your website warned us that the taxi drivers may not be too helpful when asked to go to Palmar Estates and you were correct. After asking 3 drivers who all sort of turned up their noses at us and acted like they had never heard of your place or the butterfly sanctuary we found one that would listen. I told him it was between Hotel Presidente & Fiesta Americana and he said OK. Anyway we got there in only about 6-8 minutes from the pier. Dale and Cathy Carlson ~ Louisville, KY USA

Enjoyable Day at PalMar Small Beach Club! So happy to find this small Beach Club. Great snorkeling, awesome staff, excellent yummy guacamole! Very relaxing day after being on a crowded ship. The staff were so accommodating. What surprised us was how reasonable it was. We noticed that some of ships dropped snorkelers just off shore. Check it out, a small beach club different than a expensive excursion. If you are looking for fancy this place is not it. Just nice people, good food and a nice relaxing day away from crowds.

Sherri, We had the most wonderful time with you in May! You and your staff made our weekend there in Cozumel with your great hospitality. The grounds are beautiful, food was great and the snorkeling ~ well my group just could not get enough and were amazed by the tropical sealife there off your beach. We look so much forward to coming back and seeing you again very soon. Tell the staff thanks again and say hello to the family for us as well. Take care:0) ....Happy Cruise Passenger J.
