FIRE EFFECTS
IMMEDIATE FIRE EFFECT ON PLANT:Canada wildrye is usually top-killed by fire. The coarse stems and leaves of Canada wildrye make it less prone to prolonged burning [99,100]. Little heat is transferred to crown and basal buds located just below the ground surface [74].
DISCUSSION AND QUALIFICATION OF FIRE EFFECT:No entry
PLANT RESPONSE TO FIRE:Canada wildrye responds poorly to early spring fire [74]. The best postburn response comes from summer fire [51,63]. Postfire establishment occurs primarily through seed [35].
DISCUSSION AND QUALIFICATION OF PLANT RESPONSE:Howe [51] evaluated postburn response of Canada wildrye within a tallgrass prairie of south-west Wisconsin. Canada wildrye decreased in relation to warm season associates, when subjected to early spring burn (late March) or left unburned. A decrease in Canada wildrye also occurred following mid-summer fire (15 July). However, a greater persistence of Canada wildrye was observed in mid-summer burned areas versus unburned controls. Canada wildrye showed "good" vegetative growth following a February fire in an Iowa prairie. The fire occurred directly after winter snowmelt. Although the fire had no effect upon yield, anthesis and overall growth began a few weeks earlier in burned versus unburned areas. The area studied was burned 9 years prior [31]. A "small" (2.0 hectare) August fire within a plains cottonwood (Populus deltoides ssp. monilifera) forest of Alberta had no significant (p<0.05) effect on Canada wildrye cover when compared to unburned sites [63]. An August fire in the Hayden Prairie of northeastern Iowa had no significant effect on Canada wildrye seedstalk number and height the following growing season, when compared to unburned areas. The relative production of Canada wildrye plant parts on burned and unburned areas is summarized below [30]:
The affect of fire on Canada wild rye seed germination has shown conflicting results. Rohn and Bragg [75] found no difference in germination percentage when comparing seed collected in September from spring (April) burned areas when compared to seeds collected form adjacent unburned areas. However, Ehrenreich and Aikman [30] observed greater germination on unburned areas 44%, compared to burned 8%.
FIRE MANAGEMENT CONSIDERATIONS:Slinkard and others [79] were successful broadcast seeding Canada wildrye in November within a ponderosa pine forest after a late summer fire in northern Idaho. "Excellent" stands were observed in September the following year and in July at 3 postseeding years. In burned ponderosa pine areas of the Southwest, Canada wildrye provides good erosion control [58].
