“…Our measurements of soil organic matter and pH are comparable to other studies of L. tridentata (Bolling and Walker, 2000;Titus et al, 2002) and C. ramosissima communities (Lei and Walker, 1997b) in the Mojave Desert. Although the anaerobic laboratory incubations we used to measure nitrogen mineralization do not reflect field values, they can be used as an index of relative differences in nitrogen mineralization among microhabitats and elevations.…”

“…Blank (2002) noted increased activities of N-mineralizing enzymes at inter-shrub areas (microsites) after restoration. Re-planting of sandy soils has resulted in the restoration of stable vegetation to combat desertification and has significantly improved physical, chemical, and biological soil properties (Bolling and Walker, 2000;Cao et al, 2008;Ffolliott et al, 1995;Zhang et al, 2008;Zuo et al, 2009).…”

“…Heavy compaction induces stress responses in plants, including increased levels of root exudations and altered phytohormone levels (Munns and Cramer 1996;Bengough et al 1997). In fact, soil compaction from road construction has been observed to hinder plant establishment for many decades in arid ecosystems (Knapp 1991;Bolling and Walker 2000).…”

Reduced soil compaction enhances establishment of non-native plant species

Many studies have shown that soil disturbance facilitates establishment of invasive, non-native plant species, and a number of mechanisms have been isolated that contribute to the process. To our knowledge no studies have isolated the role of altered soil compaction, a likely correlate of many types of soil disturbance, in facilitating invasion. To address this, we measured the response of seeded non-native and native plant species to four levels of soil compaction in mesocosms placed in an abandoned agricultural field in the Methow Valley, Washington, USA. Soil compaction levels reflected the range of resistance to penetration (0.1-3.0 kg cm -2 ) measured on disturbed soils throughout the study system prior to the experiment. Percent cover of non-native species, namely Bromus tectorum and Centaurea diffusa, decreased by 34% from the least to the most compacted treatments, whereas percent cover of native species, mostly Pseudoroegneria spicata and Lupinus spp., did not respond to compaction treatments. Experimental results were supported by a survey of soil penetration resistance and percent cover by species in 18 abandoned agricultural fields. Percent cover of B. tectorum was negatively related to soil compaction levels, whereas none of the native species showed any response to soil compaction. These results highlight a potentially important, though overlooked, aspect of soil disturbance that may contribute to subsequent non-native plant establishment.
