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…)
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: email@example.com). 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!

PROPOSED CLIMATE CHANGE WORKING GROUP
David Chipping (firstname.lastname@example.org)
The CNPS Chapter Council elected to explore how we might deal with issues associated with climate change, and a statewide working group is starting up with me as Chair. One thing I would love to do is to make SLO Chapter a ‘test bed’ for different approaches to the problem. I invite anyone interested to contact me and share their views.
To kick things off I see the following key issues for our consideration:
- What do climate models say about the most likely changes in climate that might reasonably be expected?
- Looking at our plant species and vegetation, where are the greatest risks given the expected climate change, in terms of many changes that might be expected. Use some existing methodology for assessing and ranking multiple risk factors.
- 3) Start doing vulnerability analyses of CNPS listed plants in our chapter area. This will include seeing what happened during the extreme stressor of the drought we have just experienced.
- Gain better knowledge of existing trends, including initiating plant surveys and gaining information on historic population distribution. Lots of field trips and field work here. We would work at the individual species and the grosser level of ‘vegetation’.
- Examine what our chapter would recommend regarding future CNPS actions and policies. For example, would we support “assisted migration” in which a plant at risk of extirpation would be transplanted into areas it has never historically occupied?
Do we, after assessing that there are too many variables that could affect future conditions, throw up our hands and leave it to Darwin to sort out?
OCTOBER SEED EXCHANGE – Marti Rutherford
The seed exchange is back. The workshop time slot (6.00-7.15) before the October meeting is reserved for our second seed exchange. So think seed collection. There will be a few minor differences. There has been a request to provide a picture of the plant that the seeds will become. This will help those who might not be familiar with the names choose plants they want to try. Our chapter will supply seed envelopes so we will be asking those bringing seeds to just bring a bulk collection of cleaned seeds labelled with genus and species, where and when it was collected and a picture. There is no need to spend your time separating into little envelopes.
The seed exchange is an opportunity to share seeds from native plants which are growing in your landscape. We will not sell seed. Do remember the legal issues of seed collection. It is illegal to collect seed from private property and public spaces without permission. If you happen to have access to rare plant seed DO NOT collect it. That seed should be reserved for seed banks and those with the skills to nurture the plant to maturity.
Keep in mind that a collection of plants grown from seed has more genetic diversity than plants grown from cuttings. Depending upon what your goal is that may be a positive point. But garden grown plant seed is not ideal for restoration planting. One would want the more pure genetics of a wild population to use for restoration. Plants grown from seed might not be like the parent plant.
There is an article on our website under resources that has information on seed collection and cleaning (link). You might find it helpful. Find it under Resources, Growing Natives, Seed Collection and Saving for the Casual Gardener.
The New CNPS Southern California Conservation Analyst position
CNPS is the voice for the preservation of California’s native flora. Many times, CNPS is the only party at the table negotiating for native plants and their places; too often, that seat is left vacant due to the fact that we have limited capacity to take on all the important conservation battles. Now, as the pace and scale of change across California increases and Federal dynamics become more challenging, it is even more critical to maintain a strong voice for native plant conservation. We need to increase our capacity to do so, and Southern California is the first place to start.
Recently CNPS received a generous bequest from Elizabeth C. Schwartz that is providing the opportunity to increase our conservation efforts. Others are making donations to match Elizabeth’s gift, so that CNPS can expand conservation staffing to better serve SoCal. This new CNPS Southern California Conservation Analyst position will support SoCal CNPS Chapters and conservation volunteers, helping grow their capacity to engage in important local conservation work. They will also engage in strategic work when plant conservation needs span multiple CNPS Chapters, advancing CNPS conservation policies, bringing together partners, and acting as CNPS’s lead representative in these regional
initiatives and processes.
It is important that this position be ongoing, since conservation success often require years of dedication and persistence. You and your Chapter can help secure the future of plant conservation in Southern California by pledging your support today. Your help will ensure that plant science and sound conservation advocacy are at the table when desert lands are at risk, when OHV routes are analyzed, where forest and grassland management is in question, and when conservation opportunities need someone there, time and again, to let decision-makers know the importance and uniqueness of the flora. Please, consider making a gift to support the SoCal conservation position; share your thoughts
with CNPS staff and your chapter leadership; and most importantly please lend your voice when important, urgent conservation issues come to your attention. Thank you in advance for your help.
Another summer has passed, and there are a few clouds on the horizon.
- The Froom Ranch project is of great concern, as it impacts Chorro Creek Bog Thistle, wetlands, and violates City policy regarding the maximum elevation for development.
- The Las Pilitas quarry project appears to be coming up again now that the political balance on the Board of Supervisors has changed, but we don’t know what changes will be proposed to justify resubmission.
- The Eagle Ranch development in Atascadero seems to have taken a step backward based on financial issues with the City, but we have no specific details.
- The Avila Ranch Project in southern San Luis Obispo does not have any apparent impact on native plants.
- We have protested any changes to Carrizo Plain National Monument.
