Phragmites
australis
Project
Need: Research, map, and monitor the colonization of Phragmities
australis in the marshes of Kitty Hawk Woods, a North Carolina Coastal
Research Reserve.
Project Objective:
- Map Phragmities
australis in the Kitty Hawk Woods marshes using Trimble GeoExplorer
GPS and aerial photography (scale 1:800).
- Survey native
plant species in the marsh throughout the four seasons.
Research Team:
ECSU - Project Leader:
Heather Allen, Research Assistants: Emma Sawyer, Matt Woolard, Reginald
Bazemore

Research - Michelle Droszcz, Northern Sites Manager, Kyle Hall - Research

Milestones:
- Mapping marshes
of Kitty Hawk Woods began in the spring 2003.
- Completion report
and PowerPoint presentation September 2003.
- Restoration project
began October 2003.
Background:
Phragmites australis,
also known as common reed, is an invasive
marsh grass that thrives in disturbed or polluted soils along roadsides,
ditches and dredged areas. It can range in height from three to thirteen
feet, and forms dense stands that invade wetland communities. P. australis
provides little food or shelter for wildlife and fish, and prevents native
plant species, such as Spartina cynosuroides, to develop.
Materials and
Methods:
- Tarkle Creek Marsh
(15 ACRES) was surveyed and native species identified and catalogued.
Very little P. australis was present there.
- Significant patches
of Phragmites were identified and mapped using GPS in Kitty Hawk Landing
Marsh, a 90 acre marsh to the north of Tarkle Creek.
- The restoration
project will set up six plots at the northwest section of the marsh,
which had a significant number of Phragmities.
- Rebar was placed
around each patch of Phragmites.
In each plot a different method of removing the marsh grass was used.
- The latitude and
longitude coordinates of the individual patches were mapped using a
Trimble GeoExplorer 3.
- A sign was posted
informing the residents of Kitty Hawk Landing about Phragmites and
the removal methods used.
Results:
After a year has
passed, the most effective removal method will be used to remove Phragmites
in the rest of the Kitty Hawk Landing Marsh. Native marsh plants will
be planted and the ninety -acre
marsh will be monitored to see if the Phragmites grows back and
how well the native plants compete with the invasive marsh grasses.
