Summary: 

Vistas of colorful fall foliage hold tremendous public and media interest, and associated tourism to the Northern Forest is estimated to add billions of dollars to the regional economy each year. This natural spectacle of diverse leaf coloration is based on the physiology of leaf pigments. In addition to its aesthetic value, the biology of one pigment (anthocyanin) may provide insights to how some trees survive environmental stress.

Effects of Global Atmospheric Change on Forest Insects

FS Research Station(s): 
Northern Research Station
Summary: 

This study concerns seasonal and annual changes in forest insect populations at the Aspen FACE experiment site in northern Wisconsin where trees are growing under both elevated CO2 (+200 ppm above ambient) and ozone (+50% above ambient).

Summary: 

Forest landscapes are changing as a consequence of climate and environmental change. These changes affect people and the forest ecosystems they depend on for clean water, clean air, forest products, and recreation. How can we best manage our forest resources to sustain this array of ecosystem services under increasing environmental stress and a changing climate? This research is leading to the development of effective strategies to adapt to these long-term changes.

Summary: 

Young communities of trembling aspen (Populus tremuloides) have been grown under elevated concentrations of carbon dioxide and elevated ozone at the Aspen FACE site, Harshaw, WI. We are using microsatellite markers to generate distinct DNA fingerprints for each of the five-aspen clones. These DNA fingerprints will be used to quantify fine-root biomass, in particular to monitor changes that occur when trees are exposed to atmospheric pollutants.

Summary: 

Methods are needed to assess the positive or negative impact of environmental pollution on forest productivity in an asymptomatic forest stand. A goal of several research groups in the Northern Research Station (NRS) is to develop a set of physiological and biochemical markers that can assess the early onset of stress in forests due to environmental factors, before injury is visible.

Summary: 

Land managers need specific information, strategies, and tools to address the unique challenges of managing forests under uncertain and changing climate and ecosystem response. Sustainable forest management is critical for both the adaptation of forests to changing climatic conditions as well as mitigation of increased levels of atmospheric greenhouse gases. The uncertainty of future climatic conditions necessitates adaptive techniques and strategies that provide flexibility and enhance ecosystem resistance and resilience. This project laid the foundation for what is now the Climate Change Response Framework, in addition to several other projects.

Summary: 

The success of forest regeneration programs depends upon the development of adaptation strategies for ecosystem sustainability under changing climates. There is a need to identify tree species and seed sources with enhanced adaptation to climate change pressures to ensure biologically and economically sustainable reforestation, afforestation, and gene conservation.

Summary: 

In 1998 the USDA Forest Service, the U.S. Geological Survey, and the National Park Service formed the Collaborative Environmental Monitoring and Research Initiative (CEMRI) to test strategies for integrated environmental monitoring among the agencies. The CEMRI project illustrates a powerful approach for tracking of environmental conditions, development of models for predicting responses of forest and aquatic processes to perturbations, estimation of future forest conditions, and identification of threats to watershed health and forest sustainability.

Climatic Indicators of Forest Health

Summary: 

Managers often need frequent, updated assessments of current and developing conditions on which to base management decisions and respond to public concerns. No methodology has been developed to indicate when a forest population is at risk to specific local and regional climate and air pollution stressors. This study resulted in an on-line information system featuring data on the relationships among various regional and global climate forcing factors and the health of forests in the north central and northeastern US, as measured by forest dieback.

Summary: 

Understanding the spatial and temporal patterns of climate variables throughout the region is important in developing effective land management strategies that can sustain our natural resources. This effort is helping to identify when and where climate and weather related disturbances typically occur in the north central and northeastern U.S.
