Climate Change and CNPS

With record global temperatures, giant storms, extended tree-killing droughts, and all the other assorted disasters we are experiencing, our fears that we humans are messing up the planet are becoming true. For CNPS, we see a lot of potential threats to the flora, as if the dead oaks and Sierra Nevada pines weren’t evidence enough. (more…)

President’s Notes February 2018

I received a telephone call last month, from a US Mail carrier who works in Ventura and Santa Barbara Counties, asking for information and ideas on ways to do something meaningful in the aftermath of the Thomas Fire.  At the time, I was moved – and still am as I reflect on our conversation – by the honest, soul-searching attitude that motivated her to reach out to CNPS in the first place.  I wrote back to her about a week later with a few links to information addressing the phenomenon of fire in California landscapes.  Now a month has passed along with the tragedies in Montecito.  I wrote back to her recently with these words (below), in an attempt to shed a bit of light on the causes and consequences of living in our natural surroundings.

Gardening Tips for Planting California Natives

With winter on the way, now is the time for us to think about planting California native plants. When we plant in the winter, or rainy season as I like to call it, we take advantage of the moist soil conditions to help establish our plants. Plants planted in the rainy season do most of their growing underground with root development. When spring comes, they respond to this establishing period by sending out new shoot growth. By summer, they are ready for the long dry months ahead and will survive on monthly waterings. (more…)

President’s Notes December 2017


As CNPS enthusiasts, we often are out in the natural surroundings, enjoying the landscapes, breathing fresh air, and getting some exercise. Who hasn’t been out on a trail or a path lately to experience a native plant community or stroll through an oak woodland? For those of us with adventure in our blood, a trip down a trail is our passport to what we study and admire out in nature. The SLO chapter has monthly field trips to destinations around the Central Coast and beyond, where we regularly get out and observe the details of plant life. And, we find this sort of activity quite fulfilling! (more…)

Invasive Species: Dittrichia graveolens (Stinkwort)

Invasive Species: Dittrichia graveolens (Stinkwort)

Dittrichia graveolens is in the Asteraceae family. It is native to the Mediterranean region of Europe. Stinkwort is erect, growing to 2.5 feet. It typically has a conical shape but can have a round appearance. It’s sometimes confused with Russian thistle (tumbleweed). It flowers from September to December and produces tiny seeds. Stinkwort’s foliage has sticky hairs covered in resin that truly stinks and sticks to and stains skin. (more…)

Sudden Oak Death Not Found in SLO’s 2017 SOD BLITZ

Sudden Oak Death Not Found in SLO’s 2017 SOD BLITZ

Kim Corella from Cal Fire has been heading up the search for Phytophora ramorum, the cause of Sudden Oak Death (SOD). She shared the 2017 SOD BLITZ results for SLO County, noting enormous participation with 289 trees sampled! Kim wanted to thank everyone who participated in this year SOD BLITZ. She notes that we were very concerned about gathering more samples in 2017 to determine the extent to which SOD was in SLO County, and is happy to report that 2017 SOD BLITZ was all negative, Apparently the 2016 SOD BLITZ survey showed false positives. The 2017 SOD BLITZ samples were tested by two completely different DNA tests and also by trying to culture out the pathogen on specialized agar. (more…)


Are you interested in vegetation sampling? Do you have a favorite plant community, alliance or association? Then please contact Melissa Mooney, chair of the newly-enlivened Vegetation/Plant Communities committee of our SLO Chapter (email: We’ve been in touch with Julie Evens and Jennifer Buck of the State CNPS Vegetation Program, and will be coordinating with the folks in the East Bay Chapter who are doing similar work. First order of business will be to prioritize what communities need focus for possible assessment and mapping and lay out our goals. Serpentine communities? Morro manzanita maritime chaparral? Valley Oak Savanna? Get those ideas coming and lets do some sampling!

President’s Update

The CNPS Conservation Conference is approaching and I am really excited! I remember well my experience at the 2015 conference in San José. I was like a kid in a candy shop. With a plethora of concurrent sessions on specific topics of intrigue, spread over three days, I was in a wonderful place – my insatiable curiosity for everything California native plants was fully gratified.

These conferences are only held once in three years. This time there are two days of workshops leading up to the conference, with topics that run the gamut from using technology to assessing different components of plant communities to creating natural landscaping and habitat gardens, from legislative action and CEQA to rare plant search and rescue, from black and white line drawing techniques and macro photography to a primer on the use of computer programs like Calflora and Calscape. Five field trips are also being offered during that time. Possibly, there is something here for everyone and it’s only the beginning!

These workshops will fall on Tuesday and Wednesday, 30th and 31st January 2018. The conference itself begins Thursday morning and runs through Saturday afternoon, 1st, 2nd and 3rd February 2018. So, what’s your interest? Environmental Justice? Lichens and Bryophytes? Fire Ecology? Climate Change in Native Landscapes? Rare Natural Communities? Citizen Science? Invasive Plants? Coastal Conservation? Oaks and Oak Rangeland? Horticulture? Grasslands and Prairies, Vegetation Mapping? Chaparral Ecology? Restoration? Native Plant Pathogens? Current Research (Student Presentations)? All the above?

The best opportunity for increasing one’s awareness on the current successes and challenges for California native plants will be at this conference! With 21 workshops, 5 field trips, over 300 presentations in 23 themed sessions, student poster sessions, botanical art, photography, music, and poetry, CNPS bookstore, and most importantly, the opportunity to learn, share, connect, and have fun all in one place – the LAX Marriott Hotel – at reasonable rates and convenient access from all over the state, this is our time and place!

Log on to “” to learn more, get details, and get enthused. Join over 1,000 fellow native plant aficionados in this CNPS ritual where science is fun. Rub shoulders with the experts and make a bunch of new friends. You know plants provide this planet with the food we eat and the air we breathe. Educating ourselves and advocating for the native plants that surround us every day, is an exciting opportunity to improve our quality of life and contribute to an infinite body of knowledge that continues to grow. So, come and join us at the Conference!!
