Phragmites australis Distribution |
Eradication of P. australis |
- porewater salinity unchanged
- P. australis eradicated
- little or no recolonization of native plant species
|
- increased porewater salinity
- P. australis eradicated
- some recolonization of native plant species
|
- latest stage of development (5 years)
- P. australis eradicated
- tidal hydrology restored
- recolonization of native plant species
|
Decreased P. australis Patch Size |
- porewater salinity unchanged
- P. australis shorter and somewhat decreased in distribution
- little or no recolonization of native plant species
|
- intermediate stage of development (2 years)
- increased porewater salinity
- signs of P. australis die-off and reduction in plant height and distribution
- some recolonization of native plant species
|
- porewater salinity at desired level
- signs of P. australis die-off and reduction in plant height and distribution
- some recolonization of native plant species
|
Similar P. australis Patch Size |
- early stage of development (6 months)
- porewater salinity unchanged
- little or no change in P. australis distribution
- native plant populations threatened by P. australis monoculture
|
- increased porewater salinity
- little or no change in P. australis distribution or apparent health
- native plant populations threatened by P. australis monoculture
|
- porewater salinity at desired level
- little or no change in P. australis distribution or apparent health
- native plant populations threatened by P. australis monoculture
