4. Monitor weed control efforts on an annual basis. Survey the property to detect
10 new invasive species or new establishment of existing species. The spring survey
and mapping will be done prior to weed control. A follow -up survey will be
conducted after control measures to insure good control and to determine if
additional measures are needed.
5. All treated areas will be re- seeded with the approved seed mix to re- establish a
competitive and beneficial plant community.
Chemical Control
1.
Where chemical control is used, the pesticide label will determine the timing and
rate of herbicide application. See attached Table 1, Chemical Control Methods
and Table 2, Herbicides to Control Downy Brome and Japanese Brome at Mines
Sites.
2.
All precautions and label instructions will be followed during the application of
the herbicide.
3.
After chemical application and before moving to a new location the equipment
used in the process will be cleaned to prevent accidental transport of weed seeds.
4.
All personnel will be trained in the use of the herbicides utilized and the safe
operation of equipment. All personnel will be trained in the identification of
target species and non - target species.
5.
No application of chemical control will be conducted when drift could potentially
happen.
• 6.
Herbicides will be applied during the time of day when the plants are most
susceptible to herbicide uptake.
7.
Herbicides will be applied when the temperature and humidity are optimum for
plant uptake.
8.
Chemical control will be sequenced during the appropriate time in the life cycle
of the plant for optimum control.
9.
Chemical control will be used in conjunction with mechanical and biological
control wherever possible.
Mechanical and Biological Control
1. Some weed species succumb to mechanical control, i.e. disking and hoeing.
When possible mechanical control will be the method of choice.
2. Annuals such as Pennycress will be disked prior to seeding with a permanent and
competitive grass mixture, see attachment for seed mix.
3. Burning will be conducted where possible, with approval of appropriate
government agencies.
4. Hand pulling of individual plants will be done for small infestations.
5. Stump cutting will be part of the control effort for Tamarisk.
6. Cattle and sheep will be used to stimulate production of competitive grass and
shrub species through grazing management using a time and timing approach.
7. Mowing before flower set will be used when possible.
