Inventory Of Sensitive Species And Ecosystems In Utah, Endemic And Rare Plants Of Utah: An Overview Of Their Distribution And Status, Utah Division Of Wildlife Resources
All U.S. Government Documents (Utah Regional Depository)
The Utah Division of Wildlife Resources (UDWR), under an agreement with the U.S. Department of the Interior, began work in March 1994 to develop a study plan for a statewide inventory of sensitive species and ecosystems. Activities enumerated in the plan include (1) completing a literature review for vertebrate, invertebrate, and plant species, (2) conducting field studies on sensitive species identified in the plan, and (3) using information obtained from the literature review and field studies to enhance UDWR's central database. UDWR's study plan was approved by the Utah Reclamation Mitigation and Conservation Commission (Mitigation Commission) in February 1995, and …

This study presents a detailed seasonal comparison of the abundance and distribution of cetaceans within 100-150 nmi (185-278 km) of the California coast during 1991 and 1992. The results of a shipboard line-transect survey conducted in July-November 1991 (“summer”) were compared to those from aerial line-transect surveys conducted in March-April 1991 and February-April 1992 (“winter”). Using a confidence-interval-based bootstrap procedure, abundance estimates for six of the eleven species included in the comparison exhibited significant (a = 0.05) differences between the winter and summer surveys. Pacific white-sided dolphins (Lagenorhynchus obliquidens), Risso’s dolphins (Grampus griseus), common dolphins ( …
