Doodletown Brook, Rockland County, NY, United States
United States, New York, Rockland County
Doodletown is an isolated hamlet in the Town of Stony Point, New York. It was purchased by Bear Mountain State Park, and is now a popular destination of naturalists.
Inside this hamlet resides Doodletown Brook, a small rocky runnel that feeds into the Hudson river. As a result, some inhabitants that are generally associated with either freshwater or oligohaline (brackish) conditions will meet in these waters, fostering a significant diversity of animals.

Bear Mountain State Park is a 21,063888km² state park located on the west bank of the Hudson River, stretching across the Rockland and Orange counties. It has served as an important place of nature preservation since 1908, being born out of conservation efforts by the Harriman family. Its woodlands are a home to a great diversity of native fish, amphibians, fish, and reptiles. As such, there are many measures taken to ensure the protection of said animals.
The biggest and most ecologically significant waterbody system are the interconnected Doodletown and Timp Brooks. Generally, these streams have high water flow, allowing temperature to remain below 23,8°C year-round. The water level tends not to fluctuate much, as annual rainfall is less than 76,2cm. The summer months are characterized by high air temperatures, ranging from 29-35°C generally, while the winter months are quite cold, ranging from -6-7°C.
Vegetation:
- Quercus rubra (Fagaceae)
- Acer saccharum (Sapindaceae)
- Underwater landscape
It is a deciduous forest, with sparse vegetation, both in and outside water. Logs and tree roots are not common in the water. Little algae is to be found.
Water is fairly shallow, with depths not ranging anymore than 2m, with much of the brook being less than 0.5m. A rocky aquascape dominates much of the brook. Water has high visibility; little sediment in the water column. As mentioned before, this brook joins the freshwaters of the mountain with the oligohaline waters of the Hudson.
As a result, many fish from either habitats will dwell, such as the following: Anguilla rostrata, Catostomus commersonii, Etheostoma olmstedi, Hudsonius hudsonius, Lepomis cyanellus (Invasive), Lepomis macrochirus, Rhinichthys atratulus, and Semotilus atromaculatus.
Fishlist:
- Etheostoma olmstedi (Etheostomatidae)
- Rhinichthys atratulus (Cyprinidae)
- Catostomus commersonii (Cyprinidae)
- Salvelinus fontinalis (Salmonidae)
- Lepomis macrochirus (Lepomidae)
- Lepomis cyanellus (Lepomidae)
- Hudsonius hudsonius (Cyprinidae)
Amphibian:
- Eurycea bislineata (Plethodontidae)
- Threats to ecology
With Bear Mountain being a state park, it is protected by the state. However, being that it is open to hikers and tourists, it is possible that some of its animal inhabitants can fall victim to pollution, littering, and poaching. Some animals, like salamanders, are indicator species, and cannot tolerate much disturbance, lest their population will drastically decrease.
I have also noticed that with the making of trails and subsequent deforestation, some erosion has taken place, destroying significant portion of habitat. That is what inspired me to create this biotope.

Comment by the expert
Lawrence Kent: Appropriate research.
Fritz Rohde: The resarch was appropriate but there is also a lot of other references out there on the fishes in that region of New York.
