Access to <br /> the burn area will be <br /> restricted. <br /> The Eugene Fire Depart- <br /> ment and the Parks and <br /> Open Space Division of the <br /> city's Public Works depart- <br /> ment will conduct the burn. <br /> Historically, prairies in <br /> the Willamette Valley were <br /> burned frequently by Native <br /> Americans.By reintroducing <br /> this ecological process, the <br /> city hopes to reduce weedy, <br /> exotic species, remove built- <br /> up thatch and provide an op- <br /> portunity to reseed the area <br /> with native prairie species. <br /> the Regisker-Guard <br /> Saturday ,Segtembtr 20)2003 <br />
