Environmental factors found to control trout hybridization

FS News Posted on: November 10, 2016
Anglers and conservationists can rest easier knowing that scientists have just identified ways to locate and preserve genetically pure westslope cutthroat trout populations into the future. A new study released today provides quantitative estimates of which specific environmental factors, such as stream size and temperature, affect the distribution of cutthroat trout and their hybrids with rainbow trout.

The growth and performance of Pinus monticola, P. strobus, and their hybrids were investigated at several sites in northern Idaho and western Montana. At three sites in northern Idaho, two hybrid progenies were approximately twice as tall and markedly excelled corresponding P. monticola progenies (having the same female parents) in height growth at age 8 years . At one site in western Montana none of the few P. monticola, P.
