DISCUSSION The year preceding sampling in July 2006 included a wet fall and winter of 2005. The spring and early summer of 2006 was mostly dry, except for March 2006 which was near average (Figures 6a and 6b). When compared to other years in which monitoring has occurred back to 1987, both the cumulative 12 months and 6 months total precipitation prior to sampling ranked 2006 near the center of the nineteen years of record for April, with total precipitation amounts dropping significantly by July (Figures 7a, 7b). Total precipitation for the previous six months was the second lowest for the period of record back to 1987 for the month of July 2006, with only the exceptionally dry year of 2002 Tower (Figure 8a, and 8b). The cumulative four month (Figure 9b) precipitation values back to 1987 show that 2006 was 40% below the 19-year average. With regard to temperature, cumulative January through June 2006 warmth was near average (Figure 10).
