CONTINUE SELECTIVE TREATMENTS OF RESIDUAL NON-NATIVE
VEGETATION IN EACH AREA AS NEEDED AND TREAT AN ADDITIONAL
AREA EACH YEAR (AS INDICATED ON THE TREATMENT MAP IN APPENDIX
A) USING TARGETED HERBICIDE APPLICATIONS, FOLLOWED BY
ADDITIONAL COVER CROP SEEDING. EMPHASIS SHOULD BE PLACED ON
MAINTAINING TRAIL RIGHTS-OF-WAY IN EACH TREATMENT AREA.
CONTINUE MOW MANAGEMENT OF THE TREATED COMMON REED
STANDS AS NEEDED UNTIL THATCH IS REMOVED.
AREAS WITH SIGNIFICANT CONTROL OF NON-NATIVE, INVASIVE
VEGETATION (>85% OVERALL REDUCTION IN COVER) SHOULD BE
SEEDED WITH A NATIVE SEED MIX IN AREAS TO BE PRAIRIE OR
GRASSLAND HABITAT. IN AREAS TO BE CONVERTED TO WOODLAND OR
SHRUB/SCRUB, HABITATS SHOULD BE PLANTED WITH NATIVE TREES
AND SHRUBS AT A RATE OF 200-400 STEMS PER ACRE AND SEEDED
WITH LOW-GROWING GRASSES AND FORBS.
SUCCESSIONAL WOODLANDS
The existing forested habitats at CLNP
are naturally occurring, early successional
woodlands with healthy native tree and shrub
growth. These areas also contain significant
populations of Alliaria petiolata (garlic mustard),
Phragmites australis (common reed), and other
non-native vegetation that thrive in understory
and woodland edge habitats, thus limiting native
understory growth. Because a little over half of
CLNP is forested and many of the species are
manageable with volunteers, these areas have
been assigned the lowest priority at this time.
As other areas are completed and evolve into
a maintenance stage, the forested habitats will
be revisited and management recommendations
will be incorporated into this plan. Some
management recommendations have been
included as opportunities for volunteer groups
and other organizations to participate in until
these areas are revisited.
Garlic mustard can be effectively pulled by hand
from April through May each spring. This should
be done prior to flowering to prevent further
spread of seed. All pulled weeds should be
bagged and removed from the site. These can
be dried and burned, or disposed of in a proper
landfill that accepts this material. These materials
should not be composted.
These pull events are great opportunities for
volunteer groups of all ages and groups of
any size. Many groups often use an organized
competition event to encourage participation,
and depending on weather, multiple pulls can be
organized each spring. Pulling these weeds is
highly effective if done consistently over multiple
years. Persistent populations can be later treated
with herbicide as needed.
