What factors are being studied in the Hubbard Brook watershed study?
Areas of research
- Hydrology, including ecosystem water flow, snowfall analysis, and long-term ice-in/ice-out measurements.
- Environmental factors encouraging or restricting tree growth, and effects of deforestation on mineral flux.
What ecological lesson did you learn from the controlled experiment on the clearing of forests as described in Hubbard Brook experiment?
Another distinguishing feature of Hubbard Brook research has been the experimental manipulations of whole watersheds, which have revealed how environmental stresses ripple through the forest ecosystem, influencing everything from soil fertility and the growth of trees to the survival of animals and the quality of water …
What is the Hubbard Brook ecosystem Study?
The Hubbard Brook Ecosystem Study is a unique public-private partnership involving the USDA Forest Service, the National Science Foundation’s Long Term Ecological Research (LTER) program, the Hubbard Brook Research Foundation, and scientists from research institutions throughout the world.
What is the main focus of the Hubbard Brook study?
The overarching research theme of the Hubbard Brook Ecosystem Study (HBES) is the response of ecosystem structure, composition and function to disturbance. Disturbances, both natural and anthropogenic, are the most important factors driving change at Hubbard Brook and throughout the Northern Forest region.
What are the benefits of conducting a controlled experiment?
Scientists use controlled experiments because they allow for precise control of extraneous and independent variables. This allows a cause and effect relationship to be established. Controlled experiments also follow a standardised step by step procedure. This makes it easy another researcher to replicate the study.
What ecological lesson can we learn from the controlled experiment on the clearing of forest?
What ecological lesson can we learn from the controlled experiment on the clearing of forest described in the Core Case Study that opened this chapter? Vegetation controls water and nutrient loss from ecosystems. Loss of vegetation diminishes the systems’ ability to retain nutrients and water.
When studying Hubbard Brook What did scientists discover?
When studying Hubbard Brook, what did scientists discover or confirm about the impact of deforestation? Researchers were able to confirm that as forests and grasslands grow, large amounts of nutrients accumulate in the vegetation and in the soil.
What does the Hubbard Brook study teach us?
Why is Hubbard Brook valuable as a study area? What does it teach us? Hubbard Brook is a valuable study area because it is an ideal watershed area. It is underlain by impenetrable bedrock and all the rainwater leaves by evapotranspiration.
What is Hubbard Brook experimental forest?
The Hubbard Brook Experimental Forest was established in 1955 as a major center for hydrologic research in New England. Located in the White Mountain National Forest in central New Hampshire, the 3,138-ha bowlshaped Hubbard Brook Valley has hilly terrain, ranging in elevation from 222 to 1,015 m.
Where is Hubbard Brook Valley?

What is the elevation of Hubbard Brook?
Located in the White Mountain National Forest in central New Hampshire, the 3,138-ha bowlshaped Hubbard Brook Valley has hilly terrain, ranging in elevation from 222 to 1,015 m. The Hubbard Brook Ecosystem Study was established by a cooperative agreement in 1963.
What is the Brook ecosystem study?
It is home to the Hubbard Brook Ecosystem Study, which was founded in 1963 and is one of the longest running and most comprehensive ecosystem studies in the world. The collaborative, multidisciplinary research efforts include long-term studies of air, water, soils, plants, and animals.
