JUNE 2005 TECIINICAL REVISION: WEED MANAGEMENT PLAN - M74-052 -DEL CAMINO
- P1T 101
Since the list of noxious weed continues to grow; and considering the development of new treatments;
this management plan is intended to retain the flexibility needed to meet future conditions and
capabilities in the arena of weed management and control. The primary species to be identified,
mapped (if found), and treated, are included as attachments: specifically included are Saitcedar and
Russian-Olive, as detailed in information from the National Pazk Service, attached. The attachment
suggests the potential range and methodology of treatment necessary for the control of identified
species.
Mapping and Identification:
Field identification and location of targeted weed species is fundamental to determining the extent and
character of weed infestation; and in the subsequent development of a treatment plan. Due to the
complex nature of identification, assistance with identification and mapping will be sought from
among Weld County Weed and Pest Division; Colorado State University Cooperative Extension
Service; U.S. Natural Resources and Conservation Service; as well as on-line and internal resources.
Mapping will attempt to identify areas of infestation within the permit boundary, and vectors of
infestation from inside or outside the permit boundary. Vectors are a consideration in prevention of
future infestation, which may affect on-site behaviors, including method and means of access within
permitted lands. An expectation that vectors from adjacent lands must be treated by adjacern
landowners if treatment on permitted lands is to be fruitful is part of continuing treatment
considerations.
Treatment:
Once the nature and extent of weeds have been mapped, and vectors identified; a course of treatment
options will be considered in order of priority of economy and effectiveness. The overall object of
weed management will be to control weeds by establishing a healthy competitive stand of vegetation
that wins the competition for plant available water. This effort is linked to on-site soil management;
including monitoring of soil fertility and percent organic matter on problem lands; relative to
distribution and amount of field available moisture on affected areas. Chemical treatment of weeds
will be the last option considered except where all other methods of competitive control fails;
including mechanical cutting, tilling, or removal of noxious weeds.
In general, weeds will be cut before a seed head can develop. This will take priority over recently
seeded areas expressing emergent grasses. Where mechanical means fail; chemical applications will
follow recommendations from previously stated sources, and applied accordingly to prevent damage to
grasses, aquatic species and wildlife. An example of Chemical treatmern and primary noxious weeds
to be identified, mapped and treated are included as attachments to this submittal. Where chemicals
are not applied by the owner/operator of infested lands, a certified applicator will be retained. A file of
all mapping and related log of treatment of identified areas will be maintained for inspection.
