Bullfrogs and fish were recorded in nine wetlands, but bullfrogs and fish co-occurred in only three wetlands (Table 1).
In this study, if the wetlands were not categorized and the single average carbon mass '(All)' multiplied to 'Total' wetland extent, the resulting carbon stock values and uncertainties (1 SD) are larger than the sum of classified estimates for both pre-settlement and current wetlands (Table 4).
Proportional to the 2011 land classes of the converted wetlands (Table 1), 57.0% of the total disturbed wetland carbon is under agricultural land use (1.1 Pg C), 7.4% developed (0.14 Pg C), 10.2% natural (0.20 Pg C), and 25.5% unspecified lands (0.48 Pg C).
Yields under the new system could be as low as those currently produced by the wetlands (Table 16), in line with the regional average of 0.63 t/ha, or as much as 0.8 t/ha, the yields expected by the World Bank agronomists for Goungel (PGRNP/MDRE 1999).
These compounds apparently persist for days, even in the presence of oxygen, and can contribute to "dissolved" metal concentrations of up to 6 × 10-7mol kg-1, whicoincidentlyntly, is close to the filtered copper and zinc concentrations obtained from the WDP1 wetlands (Table 6).
Therefore, the relations for change in areas of wetlands, emergent plants, and SAV developed for the baymouth-barrier beach shoreline class were used in characterizing water management impacts in the protected wetlands (Table 3).
Similarly, very few references report data for woody growth, which might represent a large flux of C in tropical wetlands (Table 3).
Examples of such activities include educational projects in which school children make biodiversity inventories and develop plans to protect local wetlands (Table 3) and joint efforts with the local population to assess local waste management practices.
After herbicide application to crops, major rainfall runoff from agricultural landscapes (Hunter et al. 2002) can transport relatively high concentrations of a variety of insecticides and herbicides to reservoirs and wetlands (Table 7) (Donald et al. 1999, 2005; Wauchope 1978).
Using the 1992 USGS National Land Cover Data Set NLC D) [ 20], we also evaluated nitrate levels in the USGS wells across thirteen types of land use (pasture, deciduous forest, row crops, low intensity residential, mixed forest, commercial or industrial, evergreen forest, high intensity residential, water, quarries/gravel pits, transitional, urban grasses, and woody wetlands) (Table 1 and Figure 3).
