Achieving Recovery: Research, Monitoring & Data Management


A microscopic cross section reveals the age of a native June sucker. Somewhat similar to counting rings on a tree, scientists can determine the age of June sucker.

As with most sensitive species, little information on the basic biology and habitat needs of June sucker was gathered prior to its endangered status. The limited numbers of individuals in the remaining wild population, existing in altered environmental conditions, made assessment of biological needs difficult. In advance of many on the ground actions, research is necessary to provide insight into the life history and habitat requirements of June sucker and its interactions with other species.

Results from research projects will aid in guiding recovery activities. Data produced from monitoring efforts will be used in determining the success of the program. The Technical Committee developed standard monitoring protocols for various life stages of June sucker in Utah Lake, the Provo River and other tributaries that is intended to provide trend information on population status and recruitment, habitat development, response to recovery actions, etc. Similar protocols will be developed and drafted for refuge populations. Each recovery action conducted under the Program will be monitored to assess its effectiveness.
