Abstract: A Fire History for the Turnbull National Wildlife Refuge, and the Effects of Fire on the Growth of LINARIA DALMATICA.
Kerensa DeFord, Ruth Ann Sapinsky, in cooperation with Dr. Steven J. Stein
We developed a fire history for the Turnbull National Wildlife Refuge in eastern Washington using dendrochronological methods. We determined that the fire frequency for this area was 27.5 years prior to the fire suppression policies. We also quantified the growth of Linaria dalmatica (Scrophulariaceae) in burned and non-burned areas. (Fire has been reported to have positive effects on the growth of many plant species.) We investigated the effect of fire on rament height, the number of axillary shoots and the number of flowers on L. dalmatica. We determined that fire suppression does have a negative effect on the growth potential of this rangeland weed and possible many other species.
