Monanthocloe Littoralis 



Monanthodoe littoralis biomass values were between 883 

 and 3,706 g/m" for all three stations (Table 6-7). Low 

 values were seen at all three stations in February 1997 

 (< 1,772 g/m^. Biomass increased to near 3,000 g/m" 

 in June 1997 at the Reference Station and Station II 

 and declined to values between 1,885 and 2,213 g/m' 

 in June 1999. At Station III, values increased by 

 1,205 g/m^ from February 1997 to June 1998 and 

 decreased again by 1,653 g/m* to the lowest value 

 recorded (883 g/m^ in June 1999. 



Distichlis Spicata 



Distichlis spicata exhibited the lowest biomass range of 

 all four species sampled (314 to 3,557 g/m^ 

 (Table 6-7). Values ranged between 1,047 and 

 2,199 g/m" at the Reference Station. At Station II, 

 values were similar to the Reference Station with the 

 exception of one high value recorded in January 1998 

 (3,557 g/m'^. Values at Station III were considerably 

 lower than the other two stations (314 to 666 g/m"^, 

 and on three sampling dates, coverage of D. spicata was 

 so sparse that monospecific stands could not be found 

 for sampling. 



ROOT: Shoot Ratios 



Batis Maritima 



RS ratios of Batis maritima were lowest in May 1996 at 

 all three stations (0.16 to 0.22) (Table 6-8). The ratios 

 gradually increased until January 1998 at the Reference 

 Station (0.83) and Station III (1.72) and continued to 

 increase until June 1998 at Station II (1-27). Values 

 decreased gradually at the Reference Station and 

 Station II to values of 0.36 and 0.54, respectively. The 

 ratio peaked again in January 1999 at Station III but 

 then declined to a final recorded value of 0.61. 

 Twenty-two of the twenty-four (98%) ratios measured 

 were between 0.1 and 1.0, indicating that for most of 

 the demonstration period, the plant biomass above the 



ground was proportionately larger that below the 

 ground. 



Borrichia Frutescens 



At the Reference Station, R:S ratios were greatest in the 

 summer months and lowest in the winter (Table 6-8). 

 This station also exhibited the greatest range in ratios 

 (0.2 to 0.9). At Station II, values peaked in June 1997 

 (0.83) and then gradually decreased by 64% to 0.30 at 

 the end of the study period. Values at Station III 

 showed litde variation, with the range in values being 

 limited to 0.2 to 0.4. The lowest values measured at all 

 three stations were in February 1997. All values 

 recorded were between 0.2 and 0.9. 



Monanthocloe Littoralis 



No apparent seasonal trend in the R;S ratios of 

 Monanthocloe littoralis could be seen at the three stations, 

 and ratios between stations were variable (Table 6-8). 

 At the Reference Station, values remain relatively 

 constant between 0.1 and 0.6. A gradual decrease in 

 ratios occurred from June 1998 to June 1999. A peak 

 ratio was measured in June 1997 at Station II (1.3), and 

 in June 1998 at Station III (1.1). The peaks did not 

 correspond to changes in freshwater input. Values for 

 all three stations ranged between 0.1 and 1.3. 



Distichlis Spicata 



R:S ratios at the Reference Station and Station II 

 exhibited similar patterns for Distichlis spicata, although 

 the range of values was greatest at Station II 

 (Table 6-8). Peak ratios were recorded in June 1997 

 and June 1999, foUowing periods of hea\'7 rainfall. 

 Lowest values were measured in June 1998 during a 

 period of Litde to no rainfall.
