APPLICATION NOTES

This recommendation is for terrestrial and aquatic foliar applications for invasive broadleaf, shrub and tree species on listed properties within County Parks District. All sprays shall be directed to target vegetation and evenly applied with low pressure (30-70 psi), hand held wands or guns (incl. hand, backpack and truck mounted sprayers). Timing: Depending on plant phenology, certain species may be more susceptible at different times of the growing season. Time applications for fall and spring when plants are actively growing. Avoid drought conditions or times during early spring sap flow.

Low Rate – 0.5% - Use for seedlings. Optimum effectiveness 0 to <6” height.

High Rate - 1.5% - Use for late spring through fall perennial weeds. Apply at bud to flower stage for perennials.

This recommendation covers pesticide applications within habitats for federally and state listed endangered species. A qualified biologist/staff representative that can identify all rare plant and wildlife species present shall supervise all applications of pesticide. In areas where endangered species occur, buffer herbicide applications by 40 yds when wind is blowing towards occupied habitat. A 60’ buffer shall be maintained from aquatic sites for CA red-legged frogs in all designated critical and non-critical habitat sections defined in the 2001 Stipulated Injunction. A reduced 15’ buffer applies when a certified applicator is making an application with hand-held equipment to invasive weeds. Consult project maps for locating such areas.

This pest control application incorporates all United States Environmental Protection Agency voluntary and injunction specified interim endangered species pesticide protection measures for San Mateo County including the 2001 Stipulated Injunction for CA Red-legged frogs. I certify that alternative methods and mitigation measures that will substantially reduce adverse environmental impacts have been considered and adopted as necessary and feasible.

Buffers required for CA Red-Legged Frog (CRLF) A 60’ buffer shall be maintained from aquatic sites for CA red-legged frogs in all designated critical and non-critical habitat sections defined in the 2001 Stipulated Injunction and listed in the above table. A reduced 15’ buffer applies when a certified applicator is making a spot treatment with hand-held equipment to state-designated invasive weeds within these specified sections. This reduced buffer does not apply to vegetation management projects for native brush control.
