The 2008 Growing Season: This year the growing season was much more like the recent dry and <br />drought years. Late in 2007 and early in 2008, the wet patterns of 2007 changed to a dry pattern. <br />Northwest flow, which characteristically retards precipitation, was very strong and deeply <br />entrenched. As a result, little moisture was received until August when the summer monsoon broke <br />through to some extent. By then all the subsoil gains achieved in 2007 were lost. There was a good <br />spurt of growth for a few weeks near the end of summer and the prairies that had been pretty much <br />brown all summer greened up. <br />In the Coal Creek area, by August even some of the large cottonwood trees appeared wilted <br />and dead leaves on the taller branches were evident. The stream corridor itself fared a bit better, but <br />even there growth was meager. Some areas right in the channel that have consistently shown some <br />groundwater exposure were either dry or showed only a small amount of seepage. Most of the <br />growth occurred from early August to the end of September. So, the growing season was cut short by <br />a lack of moisture until near the end of the season. <br />Weed Control Issues: Leafy spurge remains the dominant noxious weed throughout the site. It <br />can still be found in essentially every habitat on the site except reclaimed mined land, upland sand <br />near mining sites, and in the wetlands along the stream. <br />As was noted in 2007, with the increased growth of grasses due to the removal of grazing the <br />spurge declined in density throughout the area. It is still a robust and tenacious growth, but with <br />better management the spurge is not as strong as it was previously. Continued treatment with <br />herbicides and flea beatles is having the desired effect of further reducing the spurge, but there is still <br />a great deal to be done to bring the spurge population down to a reasonable level. <br />The Tamarix population treated in previous years continued to return to a very limited extent. <br />There was still some recovery of plants previously thought to be dead and a few new plants <br />appeared. But this population is still about 5% of what it was in 2006. Nevertheless, because the goal <br />is eradication, treatment will need to continue along with continued examination of other areas for <br />new populations. Those that recovered or appeared were treated again and that pattern of treatment <br />may be needed for some time before full eradication is achieved. It is well known that complete <br />elimination of this species is a long process. No new populations have been found downstream from <br />the main population. <br />Grazing Status: According to the Land Board staff, there are some plans to reintroduce grazing to <br />the Lowry Range south of Quincy, but it is not expected to be introduced to the Coal Creek corridor. <br />Instead the grazing would be kept east of Coal Creek, in the Box Elder drainage which is the next <br />drainage to the east. There might be a slight lapsing over to the high land east of the Coal Creek <br />drainage, but it is not expected to extend far down into the drainage. <br />2008 Annual Report Coal Creek Wetland Mitigation Permit DA 198811488 Page 2
