Shrub-steppe early succession following juniper cutting and prescribed fire.
Pinus-Juniperus L. (Piñon-juniper) woodlands of the western United States have expanded in area nearly 10-fold since the late 1800's. Juniperus occidentalis ssp. occidentalis Hook. (western juniper) dominance in sagebrush steppe has several negative consequences, including reductions in herbaceous production and diversity, decreased wildlife habitat, and higher erosion and runoff potentials. Pr...
متن کاملChanges in Redberry Juniper Distribution in Northwest Texas (1948 to 1982)
A Redberry juniper is a basal-sprouting, evergreen conifer that occurs in west and northcentral Texas, southwestern Oklahoma, southeastern New Mexico, and northeastern Mexico (Adams and Zanoni 1979). A distribution map, based on a 1948 Soil Conservation Service (SCS) survey of all juniper (cedar) species in Texas was prepared by Allred (1949) (Figure 1 a). A 1982 SCS survey mapped the distribut...

concentration and size of induced lesions were determined following inoculation of stems of slash pine (Pinus elliottii Englm. var. elliottii) and loblolly pine (Pinus taeda L.) with Ophiostoma minus (Hedgc.) H.P. Sydow, O. ips (Rumb.) Nannf or sterile water. In a second experiment, the rate of ethylene production and monoterpene concentration were determined following inoculation of slash pine...
متن کاملFire regime shift linked to increased forest density in a piñon-juniper savanna landscape
Piñon–juniper (PJ) fire regimes are generally characterised as infrequent high-severity. However, PJ ecosystems vary across a large geographic and bio-climatic range and little is known about one of the principal PJ functional types, PJ savannas. It is logical that (1) grass in PJ savannas could support frequent, low-severity fire and (2) exclusion of frequent fire could explain increased tree ...
متن کاملPine Regeneration Following Wildland Fire
Pine regeneration following wildland fire continues to be a serious problem across the western and southeastern U.S. Frequency of large wildfires has increased over the last several decades and restoration of these burned areas is a major problem confronting land managers. Prescribed fires are used primarily to reduce heavy fuel loads and secondarily to reduce competition or prepare sites for n...
