Update on Current Invasive Tree Pests: South American Palm Weevil, Goldspotted Oak Borer and Invasive Shot Hole Borer Fusarium Dieback Disease

Update on Current Invasive Tree Pests: South American Palm Weevil, Goldspotted Oak Borer and Invasive Shot Hole Borer Fusarium Dieback Disease

  • Casa Del Prado, Rm 101

with John Kabashim, Jennifer Pelham, and Jan Gonzales
University of California Cooperative Extension

The goldspotted oak borer (Agrilus auroguttatus) (GSOB), South American palm weevil (Rhynchophorus palmarum) (SAPW) and Invasive shot hole borers/Fusarium dieback disease (Euwallacea sp/Fusarium sp.) (ISHB/FD) are invasive, non-native tree pests causing or contributing to tree mortality in urban, natural and agricultural landscapes throughout the region. Once established in an area, they create significant economic, ecological, cultural and aesthetic losses across public and private land ownerships. Widespread tree mortality impacts wildlife, especially threatened and endangered species, through loss of a food source and habitat; creates potential hazards, especially near dwellings, along roadways, and in recreational areas; may lead to an increase of fuel loads, which can increase the severity of wildfire; and increases green waste management challenges. Additionally alarming are reports by researchers with the USDA Forest Service about the potential costs to multiple ecosystem values and public health from high volume tree mortality.

The goldspotted oak borer continues it’s expansion in San Diego County as well as isolated locations in southern California. The South American palm weevil threatens multi-million dollar industries in the state and a tree species that contributes to California’s unique landscape. At the current rate of infestation, it is estimated that Invasive shot hole borers/fusarium dieback disease will kill 26.8 million trees – nearly 40 percent of the trees in Southern California in the next few years.

Representatives from the University of California Cooperative Extension will provide updates on the latest science and programming status on these three invasive tree pests.

John Kabashima, MBA, Ph.D., Environmental Horticulture Advisor, Emeritus.

Field Trip: San Elijo Lagoon and Annie's Canyon

From Rios, the trail travels along the hillside showing coastal sage scrub disturbed by many invasive species, but there are three other very interesting communities available for the hike. The coastal salt marsh of San Elijo lagoon has a nice trail alongside with benches. It's mostly Juncus  and Suaeda but it should be great for the Nuttall's Snapdragon too. Annie's Canyon is more like a sandstone seaside cliff, with thousands of Dudleya edulis and a few shrubs and trees.  Finally, the trail continues on past Annie's Canyon up alongside the freeway to a hilltop (Solana Hills Trail) where there is a fine example of Southern maritime chaparral. Arctostaphylos glandulosa ssp crassifolia, Ceanothus verrucosus, Comarostaphylos diversifolia ssp. diversifolia and maybe Corthrogyne filagnifolia var loinifolia (all 1B.1) are up there...

Lilies and Relatives in the Laguna and Cuyamaca Mountains

Late spring is a good time to take a look for lilies and their relatives. Join us on a trip to the Laguna and Cuyamaca Mountains and be introduced by CNPS-SD Rare Plant Botanist, Fred Roberts, to a number of these species. The trip will make three stops: on the Sunrise Highway and SR 79, including a stop at the meadows at the information kiosks near the southern Cleveland National Forest boundary (Sunrise Highway); Inspiration Point (SR 79); and on a rocky knoll just north of Cuyamaca Lake. Among the species we hope to see: Allium amplectens (paper onion), Brodiaea terrestris ssp. kernensis(dwarf brodiaea), Calochortus albus (white-fairylantern), C. dunnii (Dunn’s mariposa), C. invenustus (shy mariposa), C. splendens (splendid mariposa), C. weedii (Weed’s mariposa), and Toxicoscordion venenosum (meadow death camas), and perhaps a few others. Expect other pretty wildflowers as well. It should be a good year for it...

Chapter Meeting: Mariposa Lilies of the Southern Californian Floristic Province

The mariposa lilies (genus Calochortus) include about 70 species found in western North America from British Columbia south to Guatamala with its center of diversity in California.  The mountains, foothills, and coastal regions of southwestern California and northwestern Baja California, Mexico offer 15 species.  The flowers of these bulb-forming perennials come in a in an assortment of colors and forms varying from the all-white globe-shaped white fairy lantern (C. albus) to the brilliant orange of the desert mariposa (C. kennedyi), the reds, whites, and yellows of the butterfly mariposa lily (C. venustus), and the Weed’s mariposa lily (C. weedii).  Some species are widespread, others are included in the CNPS Inventory of Rare plants because of rarity or threat.  Join us tonight as Fred M. Roberts gives us a tour of this delightful group of wildflowers. 

Fred Roberts, author of Illustrated Guide to the Oaks of the Southern Californian Floristic Province (1995) and co-author Wildflowers of Orange County and the Santa Ana Mtns. Regions (2013) has been working with native plants since high school.  He was the assistant curator of the Herbarium at the Museum of Systematic Biology at U.C. Irvine for nine years, worked as a botanist with the U.S. Fish and Wildlife Service primarily adding species to the endangered species list, and has spent the last 17 years as an independent botanical consultant, author, and artist. He is also the Chapter Rare Plant Botanist. His specialties include the flora of Orange County, oaks, lilies and their relatives, and rare plants of southern California.

Old Town Native Plant Landscape Work Party

  • Old Town Historical State Park

The Old Town Native Landscape needs your help thinning out weeds and pruning shrubs. We hope to see that the rains brought up lots of wonderful native flowering annuals!

Bring drinking water, hat, gloves, and your favorite tools for these jobs. An ordinary table fork with wide tines makes a dandy weeding tool and sharp scissors that you don't mind getting wet with weed juice can be used to snip away weeds from right around desirable annuals, without disturbing their roots in the soil.

The Landscape is north of the MTS bus/trolley/train station at Taylor and Congress Streets. This is the west end of the Park. If you come by public transit just cross at the corner and come in under the trees where we have signup, tools, handouts, and the work party leaders will find a task for you. Or if you drive, there is free parking in the lot between Calhoun and the Landscape just east of Taylor Street. Questions? Contact oldtownlandscape@cnpssd.org

Chapter Meeting: The Ethnobotany Project

  • Casa Del Prado, Rm 101

Please join us for a slideshow presentation of the book by our speakers, Rose Ramirez and Deborah Small, The Ethnobotany Project: Contemporary Uses of Native Plants; Southern California and Northern Baja Indians. Contemporary uses of 12 native plants will be discussed, including yerba mansa, bladderpod, wild cherry, creosote, elderberry, and agave, all of profound importance to the intellectual, spiritual, and cultural vitality of California native peoples. The many collaborators on this book hail from both sides of the U.S.-Mexico Border and they consider native plants their “teachers.” For this reason, the California native peoples are dedicated to passing on their traditional knowledge of native plant functions and practices to their generations and to others. We will learn how Native peoples are eloquent defenders of the land, its sacredness to them and its importance for all species that inhabit it. They have a fierce devotion to safeguarding native plants for their vital importance as foods and medicines, and in the larger cultural revitalization sweeping California in restoring the traditions of Native peoples...

Presentation by Greg Rubin: The Drought-Defying California Garden

  • South Bay Botanic Garden

Speaker Greg Rubin will present a VERY thorough slideshow that touches on most aspects of native landscaping, including basic ecology, design techniques, plant selection, site preparation, irrigation, layout, planting, and maintenance. Important differences between ornamental horticulture and native ecology will be emphasized. There will also be special attention paid to the severe threat that Argentine ants/sucking insects pose to native plants, and how they may have been a leading (but little recognized) cause of native plant mortality as long as natives have been popular gardening subjects.

Chapter Meeting: California NativeScape Garden – Past, Present and Future with Judy LaVine

  • Casa Del Prado, Rm 101

 A small garden group, the Lake Hodges Native Plant Club, was created in 1981. Ten years later, the Club entered into an agreement with the Wild Animal Park (now known as the San Diego Zoo Safari Park) to create a native garden there. Over the years, five acres of undeveloped land in the northeast corner of the Park have been transformed into a series of unique native habitat gardens (“nativescapes”) show-casing all plants endemic to San Diego County...
