Table 3.
The relative frequency and mean complex size by wetland connection type under saturated, deluge conditions
| Wetland connection type | Relative percent | Relative percent (stream connected) | Complex size (subsumed wetlands) | Complex size (subsumed and merged wetlands) |
|---|---|---|---|---|
| Lake complexes | ||||
| Wetland–lake connection (no stream or stream not downstream-connected)1 | 4.7 | 7.3 ± 0.9b | 11.2 ± 1.1b | |
| Wetland–lake–stream connection1 | 4.8 | 22.5 | 21.4 ± 8.5a | 35.6 ± 14.9a |
| Non-lake complexes | ||||
| Wetland–wetland connection (no stream or stream not downstream-connected)2 | 73.8 | 2.9 ± 0.03c | 3.3 ± 0.02c | |
| Wetland–stream connection1 | 16.6 | 77.5 | 1.2 ± 0.01d | 1.5 ± 0.02d |
| Wetlands, no observed connection | 72.1 | |||
The relative percent for no observed connection is a function of all National Wetland Inventory (NWI) wetlands, while the relative percent for connections are shown as function of all wetland connection types under deluge conditions. Streams refer to a subset of downstream-connected stream lines. Mean complex size, plus and minus standard error shows the number of wetlands in a single, surficially-connected complex under deluge conditions. Significant differences (p < 0.05, superscripts) were derived using ANOVA and Tukey HSD post-hoc tests
1Only one wetland required for a connection; 2Two wetlands required for a connection as most contain only wetlands
