Street Address/Site Name: North Davis Uplands, South Fork Preserve, Mace Ranch Park Passive Recreation Area, Woodbridge Natural Area

Detailed Location of Application Site: Along gravel paths, around seating areas and various infrastructure.

Posting and Notification: Site notifications will be posted at least 48 hours before application at site entrances and 24 hours after.

Pesticide Products: Lifeline (Glufosinate Ammonium 24.5%)
EPA Reg #: No. 70506-310
Pesticide Type: Herbicide
City Use Type: Tier 3 hazard ranking - least restrictive

Target Pests: various grasses and forbs in the identified areas

Justification for Use: This herbicide use is justified because it is the only reliable method to keep the identified areas safe and free of vegetation. The walking paths in the habitat area are gravel over compacted dirt and they can become overgrown with vegetation during the wet season due to regular inputs of new seed from natural causes and our other management activities. Mowing or string trimming are not reliable ways to manage the vegetation in these specific areas because they leave the plants and actually promote new growth on the grasses. It is also hard on equipment and operators to mow/trim over gravel because the small rocks are thrown around.
