A. Woolfolk and K. Wasson,
with assistance from N. D'Amore, K. Hayes, A. Morrow, and S. Fork, are
investigating the dynamics of the marsh-upland ecotone. We have set up
60 permanent markers around the Slough to determine whether the ecotone
is being compressed or pushed downwards in areas where invasive upland vegetation dominates
above the marsh.
To experimentally determine competitive abilities and physiological tolerances
of native and non-native plants in the upper marsh zone, we are carrying
out a transplant experiment. We also have carried out experimental restoration
of the ecotone, removing iceplant from above the marsh and replacing it
with native rushes and creeping wild rye. |
