Henry Hudson traveled as far as what is today Albany, New York.
-
The sturgeon were abundant in the Hudson River, they were one of the first fish caught in the Hudson River and are called a pioneer species. Except in 2014 they became an endangered species.
-
During the 1900’s oysters were plentiful, over 25 million pounds of oysters were harvested in 1911. Over several years these oysters disappeared from the Hudson from Pollution, dredging, and over harvesting.
-
On this date the lowest recorded temperature was 7 degrees Fahrenheit. The Hudson River Valley temperate forest with 4 seasons.
-
The record high for this span of time is 84 degrees and the record low is -3 degrees. This attached site breaks down into months the highs and lows of each month. http://www.largelandscapenetwork.org

Submerged aquatic vegetation (SAV) habitats were first starting to be mapped in 1997, water celery is the most common native SAV in the Hudson River.
-
In 2012, the Hudson River Valley was disrupted by Hurricane Sandy. There was mass flooding that engulfed the city and drug large quantities of chemicals and pollutants back into the river once the river resided. This natural disaster is considered to be a secondary succession.
-
The impact from Hurricane Sandy affected the birds as well. The wreckage from the oil spill from Sandy coated water fowls and prevented them from flying and eating, causing a decrease in water fowl population.
-
Due to Hurricane Sandy, pollutions such as oils, sewage, and industrial toxins were pulled into the river. https://prezi.com/jk60xutolmtn/pollution-of-the-hudson-river/

The food web is constantly changing but the dominate species in this climate are still the humans. We fish and eat ducks that are in the water, the fish eat crabs and clams, and they eat the bacteria and plankton.
-
The striped bass is a native fish to the Hudson River, they can live up to 30 years and there are more of these fish in the Hudson River than there are people in New York City.
-
These fish are strong and rather powerful, they are said to often chase bait all the way up to the shore. They feed on anchovies and the baby bluefish will attack anything shiny.
-
Oyster Reefs are a keystone species in the Hudson River because they provide a habiat for other important species such as: striped bass, flounder, and other types of fish. As the organisms that live there feed, they help the oyster reef cleanse itself by helping water clarity and clearing it so sea grass is able to grow correctly.

The entire Sturgeon species has been declared endagered since 1967. The sturgeons only come through the Hudson during its yearly migration.
-
After the hurricane the river grass was disturbed, also rough water made the fish run up stream and hide. After many years the grass and fish will return and flourish.
-
This eel is often confused with the electric eel, but will not shock you. They live at the bottom of the Hudson river the majority of the year except when breeding.
