Punta San Juan Comparative of the Chesapeake Bay


At Punts San Juan, there are May relations to the Chesapeake bay to which we had the chance to compare. Like the Chesapeake, the ecosystem is very unique do to the variety of plans and animals. At Punta San Juan, we stayed at research station where we stayed with scientist who regularly studied the guano birds, sea lions! and fur seals counts. They have a research station because they fear that the harvesting of guano will scare the guano birds off the property. They already have an issue with the harvesting and taking away nest grounds but with the regulations, the harvesters are able to keep a safe distance away from the patch of birds. This guano that is harvested is rich with nutrients great for agriculture and food production. They shovel the guano, put in bags, and ship them out to maybe the highlands of Peru or else where in the world. One of the many connections Peru has with the Chesapeake is that there was a boat full of guano that sank at the mouth of the Chester River.

The harvesting of the guano can relate to the harvesting of oysters because they both have sensitive effects of the harvesting that can lead to a population decline in the given region. During the guano harvesting, they collect the guano from where the bird where. This means that they have to get very close to the birds and this may scare them away. In the Chesapeake, the oyster population is down to one percent of its original population. This is due to the over harvesting and the distruction of the oyster beds. While the hare ting of oysters, watermen will use dredgers that destroy and rip up the bottom of the bed and oyster reefs. This does not allow for oysters to grow to market size and result in a population depletions. Also the harvesting of kelp Forrest is bad for the environment because the kelp act as a baffling of the ocean waves. They slow down the waves and allow for less beach erosion.

Another relationship that Punta San Juan shares with the bay is the unique ecosystem and location of the globe. The bay is an estuary and is the largest in the world. Punta San Juan is the largest marine location with the highest upwelling. What is unique about this location is the Humboldt current. It brings the cold water of the South Pacific up to the coast line of Peru which allows for a verity of fish and other polar animals. Penguins like cold polar environments and because of the Humboldt current, the Humboldt penguins are a native to the cost of Peru. The upwelling also brings different types of fish populations. The anchoveta thrive off the coast of Peru and this allows for more harvesting. But in past statistics, whenever there was a decline in the anchoveta pollutions, there was a decline in the guano birds which means less guano to harvest. In the Chesapeake bay, when ever there is a decline in the crab population, watermen struggle to making there daily quota witch results in less money and a higher demand of the crabs.

With every similarity that Peru shares with the bay, it only further reaches a better understand of how important sustaining a given population is and it’s negative effects. It only results in a disturbance in our economy but is most of the time our fault. Over harvesting increases the demand which results in less supply and increased prices. We only hurt ourselves and understanding is the first step. Peru is not the only place that can relate to the bay. I’m sure any region shares the same problems and sharing any environmental policies to save the environment will be greatly appritiate.
