Fish & wildlife Program Amendments

Biological Objectives Guidance

October 2007

The Council asks that parties make recommendations on interim or final biological objectives for the fish and wildlife program at the basinwide and province level that would be meaningful for assessing program success.

The fish and wildlife program consists of the 2000 Program, the mainstem amendments of 2003, and 57 subbasin plans adopted in 2004-05. The program is based on a science and policy framework.

Elements of the framework are:

Biological objectives have three components:

  1. biological performance, which means the response of populations to habitat conditions, such as capacity, abundance, productivity and diversity
  2. environmental characteristics, which describe the environmental conditions or changes sought to achieve the desired population responses, and
  3. the timeframe to achieve the objectives.

Biological objectives should:

Possible categories of biological objectives that fit the program framework include:

  1. Population objectives for focal species (adult abundance, ratio of natural to hatchery fish, artificial production, life history diversity/population structure, productivity; these may be expressed in trends, probabilities, averages or ranges as in absolute numbers)
  2. Species habitat potential (habitat productivity and capacity)
  3. Environmental objectives (a small set of high-level indicators such as increases in streamflow, improvements in water quality, improvements in channel structure and complexity, or removal of barriers)
