Howard collecting data while surveying for lamprey nests.Howard is the Project Leader for the Columbia River Fisheries Program Office (CRFPO). His role is to supervise the activities of CRFPO, which is responsible for the Service's population assessment of Columbia River fish and aquatic species. The CRFPO also provides for science-based management of aquatic resources in the Columbia River Basin that have been and continue to be affected by anthropogenic actions on local and regional scales. He provides technical guidance to our staff in the areas of: fish population dynamics; population viability assessment; fish recovery planning; design of monitoring and evaluation plans; evaluation of habitat restoration, water management, and artificial propagation projects; and ecosystem evaluations. He represents the Service on a number of technical and policy forums.

From 1990-1999, Howard was the Biometrics Program Leader in the Interjurisdictional Fisheries Management Program for the Oregon Department of Fish and Wildlife. In that role he supervised and participated in the development of analytical models and statistical procedures to assess, monitor, and describe factors limiting naturally produced fish populations. These analytical techniques incorporated and integrated ecology, conservation biology, and population dynamics principles using probabilistic approaches. He was the lead representative for activities of an inter-agency modeling and analytical stock assessment technical team charged with assessing Columbia River Basin salmon recovery and rebuilding activities.

From 1984-August 1990, Howard served as a Senior Fisheries Scientist for the Columbia River Inter-Tribal Fish Commission and Co-Chair of the Pacific Salmon Commission's (PSC) Chinook Technical Committee. He was responsible for developing analyses to evaluate the impacts of long and short-term fishing proposals on the coastwide chinook salmon rebuilding program and was chief technical advisor to the U.S. delegation on chinook salmon issues.
