!INVASIVE!
Perennial PEPPERWEED
Lepidium
latifolium
Please
join us in eradicating perennial pepperweed.
Please email Barbara
Warren to learn more about how you can help!
Although
pepperweed was first recorded in Peabody, MA in 1924 and
Norton, CT in 1933, it has
recently been observed spreading rapidly in Massachusetts
and Connecticut.
Most
coastal communities remain unaware of pepperweed and its
invasive potential to colonize upper wetland edges and
riparian areas as well as disturbed areas and roadways. |
 |
 |
Pepperweed
often occurs above the high tide line at the upper edges
of salt marshes and rocky pocket beaches.
|
- Perennial
pepperweed spreads both by rhizomes and by seed.
- Root
fragments as small as 2.5 cm are able to re-sprout and grow
into a multi-stemmed plant.
- Salt
tolerant, both seeds and roots remain viable in salt water and
thus may be dispersed by tidal currents, as well as by animals,
humans or vehicles.
Salem
Sound Coastwatch will be working with groups of volunteers to
locate and remove this highly invasive plant. To be successful
at eradicating pepperweed from a location, either herbicides
need to be applied or repeated hand removal of the plant.
We will be pulling repeatedly between June and October.
