Non-native crested wheatgrasses (Agropyron cristatum and A. desertorum) were used historically within the Great Basin for the purpose of competing with weed species and increasing livestock forage. These species continue to be used in some areas, especially after wildfires occurring in low elevation/precipitation, formerly Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis)/herbaceous communities. Seeding native species in these sites is often unsuccessful, and lack of establishment results in invasion and site dominance by exotic annuals. However, crested wheatgrass often forms dense monocultures that interfere competitively with the establishment of desirable native vegetation and do not provide the plant structure and habitat diversity for wildlife species equivalent to native-dominated sagebrush plant communities. During a 5-year study, we conducted trials to evaluate chemical and mechanical methods for reducing crested wheatgrass and the effectiveness of seeding native species into these sites after crested wheatgrass suppression. We determined that discing treatments were ineffective in reducing crested wheatgrass cover and even increased crested wheatgrass density in some cases. Glyphosate treatments initially reduced crested wheatgrass cover, but weeds increased in many treated plots and seeded species diminished over time as crested wheatgrass recovered. We concluded that, although increases in native species could possibly be obtained by repeating crested wheatgrass control treatments, reducing crested wheatgrass opens a window for invasion by exotic weed species.

Issues concerning the status and rights of ethnic minorities in Central and Eastern Europe have become significant in the late twentieth and early twenty-first centuries. A focus on co-nations in neighboring states, “others” in so-called nation-states, and questions of immigration dominate the media in many areas in Europe. Even though ethnic minorities and ethnic identity are part of modern conversation, the subject of ethnic minorities needs to receive serious scholarly attention to demonstrate its nuanced sense of meaning. Like nations, ethnic minorities are not static entities; they are not primordial. They are constructed or imagined in the same way nations are, even though there has been little scholarly attention devoted to minority building. In order to understand the complex meaning of an ethnic minority, one needs to view the creation of a minority—minority building—on different levels, and understand it as members of the minority understand it and as others perceive it.
