In these cases, older trees or groups of trees could either withstand wildfires or inhibit their spread because they are generally more fire resistant than grasses. Cedar was restricted to overgrazed areas along rivers and streams, and in areas of shallow soils and steep canyons where fires did not occur frequently. The golden-cheeked warbler has been listed as an endangered species since 1990, and NRI research efforts have helped to better understand their decline by studying factors such as habitat loss and fragmentation in the Edwards Plateau due to urban development (Robinson et al. Both factors endanger native wildflowers and brush plants such as Horsemint and the Tobusch Fishhook Cactus. Some owe their creation to a single process; others have been. water and the impact of woody plant encroachment of invasive species on water resources. 4.
