Herbaceous Succession after Burning of Cut Western Juniper Trees
—The expansion of western juniper ( Juniperus occidentalis spp. occidentalis Hook.) in the northern Great Basin has resulted in the wide-scale conversion of sagebrush-steppe communities to juniper woodlands. Prescribed fire and mechanical cutting are the 2 main methods used to remove juniper and restore sagebrush steppe. Mechanical treatments commonly leave cut juniper on site. Disadvantages of...
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...
متن کاملUnderstory Cover Responses to Piñon–Juniper Treatments Across Tree Dominance Gradients in the Great Basin
Piñon (Pinus spp.) and juniper (Juniperus spp.) trees are reduced to restore native vegetation and avoid severe fires where they have expanded into sagebrush (Artemisia tridentata Nutt.) communities. However, what phase of tree infilling should treatments target to retain desirable understory cover and avoid weed dominance? Prescribed fire and tree felling were applied to 8–20-ha treatment plot...
متن کاملThe response of understory herbaceous plants to nitrogen fertilization in forests of different land-use history
Forests growing on former agricultural land often have reduced frequencies of many native forest herbs compared with forests that were never cleared for agriculture. A leading explanation for this pattern is thatmany forest herbs are dispersal limited, but environmental conditionsmay also hinder colonization. We examined the response of six forest herb taxa (Arisaema triphyllum, Cimicifuga race...

fine sandy loam (fine-loamy, siliceous, semiactive, thermic Typic Paleudult) with a slope of 1–10% (Kerr et al. 1980). The other complex (92° 38 W, 31° 8 N at 66 m above sea level) is comprised of Beauregard silt loam and Malbis fine sandy loam (fine-loamy, siliceous, subactive, thermic Plinthic Paleudult) with a slope of 1–5%. Before harvesting, Study 2 was a closed canopy, mature, loblolly pi...
