DIRT - Detritus Input and Removal Treatments	Relationships LTSEs: DIRT: Detrital Input, Removal, and Transfer (University of Michigan Biological Station) LTSEs: DIRT: Detrital Input, Removal, and Transfer at H.J. Andrews Description: The DIRT Experiment (Detritus Input and Removal Treatments) is a long-term study of controls on soil organic matter formation. Our goal is to assess how rates and sources of plant litter inputs control the accumulation and dynamics of organic matter and nutrients in forest soils over decadal time scales. Results from 11 years of field and laboratory studies demonstrate the relative importance of above- and belowground sources on soil organic matter (SOM) dynamics and show emerging long-term non-linear changes in soil carbon release and storage. ref: Harvard Forest website - http://harvardforest.fas.harvard.edu/data/p00/hf007/hf007.html

LTER - U.S. Long Term Ecological Research	Relationships LTSEs: Coweeta Hydrologic Laboratory - USDA Forest Service LTSEs: DIRT: Detrital Input, Removal, and Transfer at H.J. Andrews LTSEs: Konza Prairie LTSEs: McMurdo Dry Valleys LTSEs: Sevilleta Website: http://www.lternet.edu/ Description: * The Long Term Ecological Research (LTER) Network is a collaborative effort involving more than 1800 scientists and students investigating ecological processes over long temporal and broad spatial scales. * The Network promotes synthesis and comparative research across sites and ecosystems and among other related national and international research programs. * The National Science Foundation established the LTER program in 1980 to support research on long-term ecological phenomena in the United States. * The 26 LTER Sites represent diverse ecosystems and research emphases * The LTER Network Office coordinates communication, network publications, and research-planning activities.
Nutrient Network	Website: Nutrient Network Description: Two of the most pervasive human impacts on ecosystems are alteration of global nutrient budgets and changes in the abundance and identity of consumers. Fossil fuel combustion and agricultural fertilization have doubled and quintupled, respectively, global pools of nitrogen and phosphorus relative to pre-industrial levels. Concurrently, habitat loss and degradation and selective hunting and fishing disproportionately remove consumers from food webs. At the same time, humans are adding consumers to food webs for endpoints such as conservation, recreation, and agriculture, as well as accidental introductions of invasive consumer species. In spite of the global impacts of these human activities, there have been no globally coordinated experiments to quantify the general impacts on ecological systems. The Nutrient Network (NutNet) is a grassroots research effort to address these questions within a coordinated research network comprised of more than 40 grassland sites worldwide.
Rothamsted	Relationships LTSEs: Broadbalk Winter Wheat Experiment LTSEs: Park Grass Website: http://www.rothamsted.ac.uk Description: The mission of Rothamsted Research is to be recognised internationally as a primary source of first-class scientific research and new knowledge that addresses stakeholder requirements for innovative policies, products and practices to enhance the economic, environmental and societal value of agricultural land.
Soil Monitoring Cooperative	Description: Two workshops have been held in Troy NY, in 2007 and 2008, to organize individuals interested in soil monitoring in the Northeastern USA and Eastern Canada. The group is growing in size and interest, plans to meet in the future, and is writing a peer-review paper.
Victorian Long-term Agro-ecological Sites Network	Website: http://www.dpi.vic.gov.au/dpi/vro/vrosite.nsf/pages/lwm_ltae Description: What is the LTAE network? The long-term Agronomic-Ecological research sites (LTAE) and expertise of custodian scientists represents a research network across the agro-ecological zones where cropping occurs in Victoria. The network currently includes locations at Horsham, Rutherglen and Walpeup (Figure 1). These sites recently underwent a rigorous review process that made several important recommendations for their future use with regard to researchers, stakeholders, and the public good value for the community (Crawford et al. 2003).
