Department of Defense (DoD)¹ holds primary responsibility for defending the U.S. DoD’s numerous military bases and research and administration facilities make it one of the largest landholders in the country, and its Army Corps of Engineers division performs many of the public works duties of the Federal government.

Defense Environmental Network and Information Exchange (DENIX) - DENIX is the central platform and information clearinghouse for environment, safety and occupational health (ESOH) news, information, policy, and guidance.

Deputy Under Secretary of Defense For Installations and Environment (DUSD(I&E)) -

Conservation: Natural/Cultural Resources - Supports the military mission by providing for sustainable use of its lands, sea and airspace; protecting natural and cultural valuable resources for future generations; meeting all legal requirements; and promoting compatible uses of those resources. DoD activities in conservation are found under the following main topics:

• Animals & Birds

International - Develops frameworks for international military-military cooperation that integrate environmental compliance, awareness and stewardship into all operations.

Technology - Seeks new technologies that meet environmental requirements at less cost.

Strategic Environmental Research and Development Program ( SERDP ) - identifies, develops, and transitions environmental technologies that relate directly to defense mission accomplishment. One of its research areas is conservation which includes: cultural resource management; ecological forecasting; ecosystem res toration and mitigation.

Tri-Service Ecological Risk Assessment Workgroup (TSERA-WG) - coordinates and develops uniform technical guidance for the conduct of ecological risk assessments (ERA) at DoD sites worldwide.

The Armed Forces Pest Management Board (AFPMB) – Recommends policy, provides guidance, and coordinates the exchange of information on all matters related to pest management throughout the Department.

• Formerly Used Defense Sites - Similar to the Base Realignment and Closure division, but focuses on Department of Defense properties not used specifically as military bases. These include office and manufacturing areas and storage and research facilities. This land often suffers from the same contamination as former military bases and must undergo remediation before it is redeveloped or turned into open or wild space.
• Institute for Water Resources - Assists the Corps and other water management agencies by performing forward-looking research and analysis of emerging water-resources issues.
