One important cool-season perennial grass seed crop grown in Oregon is fine fescue (Festuca rubra L.). Open-field burning has been used for many decades to manage pests, cycle nutrients, and stabilize yield, in fine fescue seed fields, especially as stands age.

I evaluated fire occurrence, growth and recruitment and determined the fire history of 21 old and 20 young 8ha stands in Cascade, Siskiyou and mid-Coast mixed conifer and evergreen forests in southwestern Oregon. The rates and patterns of growth were measured and analyzed on 1,079 old-growth and 2,111

The Ataspaca prospect is in the Cordillera Occidental, 45 km northwest of Tacna, Peru. Epizonal intrusions satellitic to the Caplina- Ataspaca pluton were emplaced 41 m.y. ago into limestones of the Lower Jurassic Pelado Formation along the northeast-trending Chucchuco fault system. Depths of emplacement ranged from 4.5 to 6.0 km....
