Trees need nitrogen and phosphorus to grow, and in many temperate forests of North America and Europe these nutrients have become scarcer relative to what plants demand. This slow decline is called oligotrophication.

What they work on

  1. Use long-term data from four Hubbard Brook monitoring sites to quantify how tree carbon allocation above and below ground has changed with shifts in soil nitrogen and phosphorus and their uptake by plants.
  2. Test whether trees facing nutrient decline gain more phosphorus than nitrogen from soil, using stable isotope tracers at fourteen sites along an elevation gradient in northern hardwood forest.
  3. Identify which soil microbes actively mobilize nutrients using isotope probing of microbial communities, linking microbial activity to plant nitrogen and phosphorus acquisition.
  4. Build AI-assisted process-based models of belowground carbon allocation and nutrient uptake to project whether forest growth eventually outstrips soil nutrient supply.

More about the research

It raises a basic question about forest health: when soil nutrients run short, can trees compensate, and for how long?

Why it matters

Declining nitrogen and phosphorus could reduce the long-term growth of northeastern U.S. forests. By testing whether and for how long trees can compensate by investing carbon belowground, this work could improve forecasts of forest health and productivity. That information matters for the forest-based economy, including partners in the New Hampshire Forest Economy Alliance, and for public outreach materials aimed at local communities and schools.

Known grants
