Investigations of Bromus tectorum: restoration strategies and interactions with arbuscular mycorrhizal fungi
… soil community and sucrose additions with native seed applications to improve native species growth and establishment. Sucrose reduced both n. B. tectorum and other annual plant species abundance and richness. Although soil community addition reduced B. tectorum, it did not appear to increase …

Response By Upland Nesting Birds to Three Rejuvenation Treatments Applied to Two Types of Seeded Nesting Cover in Eastern South Dakota
<p>Seeded nesting cover reaches peak growth 3-5 years after planting and characteristics, primarily height and density, attractive to many upland nesting birds deteriorate after the year of peak growth. I studied the effects of 3 rejuvenation treatments (haying, haying and scarifying, haying and …

Evaluating native warm-season grass and wildflower mixtures for beef cattle production in the Mid-Atlantic
… across treatment, which suggests lower WF seeding rates can generate comparable pollinator resources. Major findings from these experiments suggested that spatial or temporal separation of NWSGWF was unnecessary to generate successful establishment, varying the ratio of NWSG-WF in seed …

The Use of Veld Restoration Techniques for Rehabilitating Degraded Waterberg Mountain Bushveld in Lapalala Wilderness Reserve, Limpopo Province
… applied, including soil ripping, sowing grass seed mixtures, and covering treated areas with single and double layers of thorn branches known as brush-packing. These treatments were duplicated at two sites within the game reserve, one of which was located inside the enclosure of the Lapalala …

Factors controlling the establishment of species-rich grasslands in urban landscaping schemes
… has generally involved the use of commercial seed mixtures. The present study has experimented with the use of freshly cut hay as a seed carrying medium and has considered some of the factors thought to be important for the creation of new species-rich grasslands. Two meadows, established in …

Potential for the restoration of lowland and wet grassland upon ex-arable land
… An investigation to determine whether soil seed banks of former, and extant, floodplain grasslands could contribute to the restoration of floristic diversity concluded that propagule availability was likely to be a major constraint on restoration and recreation of wet grassland as seed banks …

Differential dry matter production, nutritive value and grazing utilisation of perennial ryegrass varieties and mixtures evaluated within intensive grazing regimes
… ryegrass varieties sown as monocultures and mixtures was conducted to evaluate the use of mixtures. <br/>Residual Grazed Height (RGH) was developed as a measure of grazing efficiency. Significant differences in grazing efficiency were recorded between varieties evaluated under animal grazing, …
