  • Research Interests and Activities:
    Steven P. Hamburg's research interests include forest dynamics, historical ecology, calcium biogeochemistry, disturbance ecology and climate change impacts. He is particularly interested in the role of human disturbance, multiple stresses and climate change on forest structure and function. He has established a long-term (23 year) old-field successional study on a site with similar edaphic and elevational characteristics to the experimental watersheds within the Hubbard Brook Experimental Forest. He has pioneered the use of quantitative soil pits for monitoring long-term dynamics in soil nutrient and carbon pools. He has been active in the Intergovernmental Panel on Climate Change, most recently as lead author on the Special Report "Land use, Land-use Change and Forestry". He has appeared before Congress and a wide variety of other forums, testifying on the impacts of climate change on forest structure and function. He co-chaired the first meeting of the East Asia and Pacific Region International LTER network, and currently serves as co-chair of the US Liason Group to the network.

    Role at the Hubbard Brook:
    I am interested in the effects of disturbance history on northern hardwood forest structure and function. This includes agricultural uses, and their effects on patterns of forest regrowth and nutrient distribution in the White Mountain region. I have also been following the effects of the WS-5 whole-tree harvesting on soils C and N over the past 15 years, and shifts in calcium cycling in response to clear cutting and agricultural disturbance.
