Program now available! Download here (pdf).

As always, the Symposium will feature presentations on the latest in research and management, with a broad range of presentations, posters, exhibitors, discussion groups, trainings and field trips, with activities like our photo contest, awards, and social hour mixed in. Trainings and a session on DPR Laws & Regulations will be held Wednesday; sessions will be on Thursday and Friday, with the one-day HCP conference also on Thursday; and field trips on Saturday. We anticipate DPR CEUs (12 hours "Other" and 2 hours "Laws & Regs", with additional "Other" for trainings and field trips.) The full program will be posted in early August. This year, we have sessions featuring:

  • New Tools for Invasive Plant Management
  • Strategies for Eradication Success
  • Desert Weeds of Alta and Baja California
  • Working with Conservation Corps
  • Stopping the Next Invaders

Training: Strategic Approaches to Wildland Weed Management
Wed., Oct. 28, 9-4pm with instructors Steve Schoenig, Andrea Williams, Brent Johnson, Gina Darin and Jason Giessow. This training will include talks on principles of weed management, writing goals and objectives, management strategies, risk assessments and prioritization, permitting, implementation plans and adaptive management, in addition to group exercises that build on the day's curriculum.
Location: Mission Trails Regional Park (1 Father Junipero Serra Trail, San Diego. See directions.)

Training: Calflora Weed Manager
Wed., Oct. 28, 1-4pm. Did you know that you can map weeds on your smartphone, using a custom interface designed for your organization? That you can record details each time you treat a population? Calflora's Weed Manager suite of tools is designed to do this and more. Come learn the basics from Calflora staff.
Location: Casa Del Prado, Room 104, Balboa Park (1800 El Prado, San Diego. See map.)

Updates on Pesticide Use Laws & Regulations
Wed., Oct. 28, 6-8pm. These DPR updates are included with Sympoisum registration. Space is limited andDPR-licensed applicators have priority.
Location: Santa Fe Room, Balboa Park Club, Balboa Park (2144 Pan American Rd W, San Diego. See map.)

Field Trips: We will have two full-day and one half-day trips on Sat., Oct. 31:

  • Habitat Restoration and Enhancement on the Cleveland National Forest (full-day, 8:30-4:30pm)
    In Cottonwood Creek, tamarisk removal and subsequent restoration of native, riparian habitat has benefitted listed species including the arroyo toad, least Bell's vireo and the southwestern willow flycatcher. In Thing Valley, we will discuss nonnative annual grass control in montane chaparral and the fire/chaparral/non-native grass issues faced in eastern San Diego County.

  • Non-native Grassland/Forbland Restoration Using Various Techniques on Rancho Jamul Ecological Reserve and the South Crest Preserve (full-day, 8:30-5:30pm)
    On Rancho Jamul, native grasslands/forblands have been type-converted to non-native grasslands/forblands. Various restoration techniques are being tested including fire, herbicide applications, mowing, line trimming, and seeding are being tested to determine the most practical native grassland/forbland restoration method, in turn benefitting the federally endangered Otay tarplant. At South Crest Preserve, multiple restoration techniques have been tested to determine the most practical and cost effective method(s) for controlling Brachypodium distachyon and enhancing the native seedbank.

  • UAV Demonstration (half-day, 8:30-1pm)
    On site at Black Mountain, Aerial Conservation and The Nature Conservancy will demonstrate and discuss the use of unmanned aerial vehicles (UAVs) for weed mapping.

  • Special HCP Conference: This parallel event shares several sessions with the main Symposium on Thursday, but heads off in its own direction for several sessions as well. The conference looks for opportunities for regional Habitat Conservation Planning to support landscape-level invasive plant management. See the HCP Conference page for more details.
