Grassland Management With Prescribed Fire

This circular provides an overview of the use of fire in grassland management. It describes the history and importance of fire in the grassland ecosystem, how plants respond to fire, and the uses and potential benefits of prescribed fire. It also summarizes fire planning and legal and safety considerations. And finally, it provides guidance on some special uses of fire. when burning conditions ...

The Use of Prescribed Fire to Control Invasive Exotic Weeds at Jepson Prairie Preserve

Jepson Prairie in Solano County, an outstanding example of remnant California Central Valley vernal pool and grassland habitats, is threatened by invasive exotic species. This paper describes the results of a 200-acre late-spring prescribed fire conducted at Jepson Prairie in June of 1995 and aimed at reducing the cover of an extensive infestation of Medusahead (Taeniatherum caput-medusae). Bur...

Altered Rainfall Patterns, Gas Exchange, and Growth in Grasses and Forbs

Although the potential for increased temperature is the primary and best-studied aspect of anthropogenic climate change, altered rainfall patterns, increased storm intensity, and more severe droughts are also predicted in most climate-change scenarios. We altered experimentally the rainfall regime in a native tallgrass prairie in northeastern Kansas and assessed leaf-level physiological activit...

Competitive Effects of Various Grasses and Forbs on Ponderosa Pine Seedlings

Competition between ponderosa pine seedlings and various grasses and forbs was studied on :I site in northern Arizona burned in 1982 by a wildfire. Two-yearold pine seedlings were planted in 3.05 x 3.05 m plots in April 1983, followed by the sowing of grass and forb seeds on the same plots in July 1983 after summer rains had begun. Predawn xylem water potential of the pine seedlings was measure...
