Your SLO CNPS chapter recognizes the importance of helping students begin their careers in botany. Several years ago, the Malcolm McLeod Scholarship was established to help graduate students fund their research with scholarships in the $300‐$1000 range.
This year there are three recipients.They are Kristen Nelson, Understanding the ecological impacts of Eucalypus globulus on California native habitats; Julia Harencar, Indistinguishable Species of Goldfields: A case of Ecological Selection; and Lindsey Whitaker, Managing for biodiversity in the Guadalupe Nipomo Dunes and the rate of invasion by invasive grass, Ehrharta claycina (Veldt grass).
Put our June 1 chapter meeting on your calendar. These students will be joining us to do presentations on their research.
Hopefully many of you are remembering that we will have our ﬁrst seed exchange before the October meeting.
If you are interested in participating, now is the time to start closely observing your plants for seed formation and maturation. I have already started taking a few seeds from my Ranunculus californicus (buttercup), Lepechinia calycina (pitcher sage), and Heuchera maxima (island alum root). With a neighbor’s permission I have wandered her pasture collecting seed from Callindrinia ciliata (red maids). By the time this appears in the newsletter I suspect I will be gathering from my Stipa pulchra and Melica californica. So hone your observational skills, get close to your plants, and collect seeds!
I’ve included this article regarding information on the collection and cleaning of seeds for you to download.
This document talks about Why and When to collect native plant seeds and offers tips for collecting and storing seeds. By Marti Rutherford, CNPS-SLO, April 2016
Lauren Brown crafted our chapter’s comments on the Guadalupe-Nipomo Dunes (GND) Draft Comprehensive Conservation Plan (CCP) and Environmental Assessment(EA). The CNPS SLO Chapter fully supports the proposed management Alternative B (moderate increase in wildlife and habitat management, incremental increase in visitor services and environmental education). If budget considerations do not allow implementation of Alternative B, we would support Alternative A (no action), where the current level of management and public use opportunities are maintained. We strongly oppose Alternative C (minimal wildlife and habitat management and the Refuge is closed to the public), as written, for the following reasons: (1) the minimal level of monitoring and maintenance described in Alternative C is insufficient to ensure the continued existence of these species within the Refuge; (2) we concur with the findings of the EA that a decrease in the current level of invasive species management, as proposed in Alternative C, will increase the threat of invasive species to degrade and potentially destroy wildlife habitat within the refuge, and adjacent to the refuge; (3) decreased oversight will fail to detect newly introduced invasive species; and (4) feral swine must continue to be controlled due to the damage they cause.
El Villaggio Development
CNPS was represented by Dr. Neil Havlik in our opposition to the proposed annexation and development of the El Villaggio development on Los Osos Valley Road and Calle Joaquin (the southwest corner of the intersection). Dr. Havlik testified that (1) the City’s General Plan requires that new development in the Irish Hills stay below the 150 foot elevation line. The current proposal ignores that restriction and extends well above that line in two areas of the property. One of these locations contains at least two plant species of concern in the City’s General Plan (Chorro Creek bog thistle and clay mariposa lily) and likely others. The nearby Vineyard Church was developed in the County (which had and has no elevation limit for development) and should not be used as a justification for the City abandoning its stated policies; (2) even if rare plants are “protected” by a 50 ft. buffer, the project will likely affect the hydrology required by the bog thistle; (3) there are serious wetlands impacts including so-called restoration of Froom Creek which is essentially destructive channelization, and apparent destruction of wetlands along Calle Joaquin.
Sadly, the SLO City Council was unanimous in letting the project move forward, so that our next opportunity to stop the project will be the issuance of an EIR.
Cape-Ivy gall fly + weeds
In other issues, the chapter is supporting the proposed release of Cape-Ivy gall fly, following may years to testing that the gall fly will only affect cape ivy. We wrote a support letter to the Animal and Plant Health Inspection Service (APHIS) at the request of California Invasive Plant Council. Several other issues regarding dangerous pests that we will be considering are the impacts of new giant tumbleweed that has arrived from the Central Valley, the spread of Sahara mustard in Los Osos, and the migration of polyphagous shot hole borer as it moves north from the LA Basin, killing a wide variety of trees. People interested in working on these issues should contact me or Mark Skinner who is taking over from Lauren Brown on weed issues.
Saturday, April 2, 2016, Malcolm McLeod Annual Field Trip Meeting to Shell Creek co-lead by Dirk Walters and David Chipping. This is our monthly meeting for April. Meet at the San Luis Obispo Veterans Hall, 801 Grand Avenue (corner of Grand & Monterey Boulevard) at 8:30 a.m. and/or the Santa Margarita Park & Ride (intersection of Hwys. 101 and 58) at 9:00 a.m. Bring your “Wildflowers of Highway 58” plant guide by Dr. Malcolm McLeod or plan to purchase one for 10 on the trip. For more information call Dirk Walters at 543-7051 or Dave Chipping at 528-0914.
A seed exchange is being planned as an activity for the workshop time slot before the October meeting. Learn about how to gather, how to prepare, and a bit about seeds in general. This should provide a fun event for those interested in growing natives from seed.
This seed exchange is intended for native plants on your property. If collecting elsewhere, make sure you have the correct permits or permissions. Collection of seeds without permission is illegal. If you have rare plants please do not collect seed for this exchange. You might want to coordinate with the rare plant group to possibly collect those seeds for seed banks.
Seeds should be labelled with Genus and species if known. Label also with date, location obtained and your name. Either prepare individual packets (recycling junk mail envelopes works here) or bring in bulk but have envelopes for people to use. It is preferred that seeds be cleaned but this is not absolutely necessary. This is intended as a free exchange. Do not plan to sell seed.
If you don’t want to participate in the exchange but would be willing to donate seed for the fall plant sale please label your seed as above and give to Marti Rutherford. In addition the propagation group would like to experiment with seeds that are difficult to germinate. These are often not appropriate for the casual gardener because of the germination difficulty but the group could play with some seed treatments to see what might improve germination. Seeds from plants such as manzanita, bush poppy, matilija poppy, blue eyed grass, wooly blue curls fall into this category. We recognize that there is some debate about whether garden grown plants are a good source of seed for restoration, but this will allow us to experiment with techniques.
Any seed left behind at the exchange will either be packaged to sell at the plant sale or given to individuals in the propagation group.

I’m pleased to start an Invasive Species Watch column to Obispoensis. I’ve been in the invasive species removal business since 1999 mainly working in the Guadalupe-Nipomo Dunes and San Luis Obispo Creek. Those that know me many not think of me as a warrior however many people (thanks CCC’s!) and I have been battling bad guys such as Arundo, jubata grass, veldt grass, European beach grass, Russian wheat grass (some of the most insidious weeds are grasses!) cape ivy and ice plant for a long time. The satisfaction of this work arrives when a formerly infested area is re-taken by native plants. The best memory I have is from 2002 when a heavy veldt grass infestation was sprayed out at the then Tosco Buffer (now Phillips 66) which was followed by a lush wildflower display of goldfields, dune larkspur, owl’s clover, baby blue eyes, blue dicks, sky lupine, and fiddleneck. I’m still working on the same weeds and I’m seeing progress: Russian wheat grass and jubata grass have been nearly eradicated from the Dunes! In future pieces I’ll be describing specific invasive species and what’s being done to control them.

The Guadalupe Nipomo Dunes National Wildlife is presenting a Comprehensive Conservation Plan and its Environmental Assessment to the public with a comment period that ends on April 16. A public meeting will be held at the Ramona Garden Park Center in Grover Beach on March 22, 5:30-7:30.
The Refuge’s Draft Vision Statement is “To conserve the dynamic landscape and imperiled natural resources…” and “… we protect the Dunes Complex for everyone’s enjoyment…” and “…the service works cooperatively with other agencies, nonprofit organizations… .” The history is that the refuge has probably been successful in the protection of certain species, especially snowy plover, and CNPS serves on an advisory committee regarding weed abatement. Issues of public interaction have improved lately.
The plan cites three alternatives. Alternative A is “No Action” which would continue management as in the past. Alternative B increases actions to protect species, and increase interaction with the public. SpeciWic mention is made of protecting habitat for La Graciosa thistle and marsh sandwort, while directing foot trafWic away from plover nesting areas. Alternative C is rather troubling, as it “will take into consideration the forecasted decline in budgets for the NWRS, proposes to reduce or eliminate many of the current management activities occurring on the refuge, as well as close the refuge to all public access.” The clear interest of CNPS is support of Alternative B, but also to offer CNPS as a more active partner in conservation of the dune habitat. Alternative C must not happen as it would, among other things, shut CNPS out of the refuge and access to Coreopsis Hill. You can send comments to: PaciWic Southwest Region, Refuge Planning, U.S. Fish and Wildlife Service; 2800 Cottage Way, W+1832; Sacramento CA 95825
You can email comments to firstname.lastname@example.org including “Guadalupe-Nipomo Dunes CCP” in the subject line.
The 21st Annual Spring Outing Botanical Excursion Foray, Retreat, and Escape to the Environment Brought to you by the new Bryophyte Chapter of the California Native Plant Society!
Friday to Monday, March 18-21, 2016 North Coast Range near Occidental, California
Founded in 1996, SO BE FREE is a series of West Coast forays started by the Bryolab at UC Berkeley, but open to all botanists. The main focus is on bryophytes, but we also encourage experts on other groups to come along and smell the liverworts. We welcome specialists and generalists, professionals and amateurs, master bryologists and rank beginners.
SO BE FREE is held each spring, somewhere in the Western US, associated with spring break at universities. Evening slide shows and informal talks are presented as well as keying sessions with microscopes. In addition to seeing interesting wild areas and learning new plants, important goals for SO BE FREE include keeping West Coast bryologists (and friends) in touch with each other and teaching beginners.
To see pictures and information from past outings, visit the SO BE FREE website (http:// ucjeps.berkeley.edu/bryolab/Field_Trips.html).
Early Registration Deadline is Dec. 15, 2015. Regular registration Deadline is Feb. 19, 2016

Conservation Committee Update
Margarita Area Specific Plan development area
When developers graded a population of Sanicula maritima without getting a permit from the California Dept. of Fish and Wildlife, the Department, the City of San Luis Obispo and CNPS were concerned. It turns out several populations sit in the Margarita Area Specific Plan development area, and the fate of the populations regarding mitigation is, at the time of writing, unclear. Whatever the outcome, our chapter will conduct a survey of the county to see if we can find any more populations of the plant and to assess the possibility of starting new populations. Bear in mind that CNPS has a long standing policy against mitigating losses by moving plants to other sites. Transplantation seldom works, and is not a valid mitigation for destroyed habitat in the Margarita Specific Plan. Gaining knowledge of the plant’s status and the most suitable habitats will better inform our response to this issue.
Land application of biosolids
County planners took a proposed revision of the ordinance on the land application of biosolids, the ‘nice’ term for the dried sludge coming from sewer plants. Planners wanted to start an EIR but a split Board declined as the interim ordinance seems to work and is good for another two years. Commenters stated that the proposed ordinance does not meet the requirements spelled out by the Board and a Sewage Sludge Land Application Task Force in 2002. CNPS has been concerned that sludge might be dumped on rangeland or agricultural marginal lands, thus changing nutrient balances and habitat, so we will be keeping an eye on the issue.
The carbon recycling issue is at the core of global warming issues, and warming was made evident by the current blooming of Chorizanthe populations on serpentine in eastern Montana de Oro Park. I hope the pollinators will be around to do their work.
Bonnie’s drawing for this issue of Obispoensis is based on a picture sent to me by George Butterworth. The species, Cucurbita palmata, has many common names. The ones I found on the web include coyote melon, coyote gourd, desert gourd, palmate-leafed gourd, coyote ear, buffalo gourd, stinking melon, calabazilla, or chilicote.
Coyote melon is primarily a desert species that grows best where there are summer monsoons. Since we are a little north of the summer monsoon track coyote melon is relatively rare in our area. However, a few plants can be found in the eastern edge of our Chapter area (i.e., Carrizo Plain and the upper Cuyama Valley). It’s a species that prefers sandy, disturbed soils where vegetation is scarce such as desert washes and dry, rocky slopes.
The most common name around here, coyote melon, refers to its vegetative resemblance to the pumpkin, squash cucumber, melon, or gourd, family Cucurbitaceae. The Cucurbitaceae are non-woody (herbaceous) vines with tendrils and broad, palmate-veined leaves. Flowers in coyote melon are unisexual (staminate or pistilate). In coyote melon they are large and yellow and borne solitarily in the in the axils of leaves. Fruits in the family are extremely variable and are considered unique to the family. Often it is a kind of quite large berry botanists call a pepo. Pepos have fleshy, fibrous, or watery flesh inside and usually are enclosed by a clearly defined outer skin or rind. When totally mature, they often dry out to a hollow dry spheroid.
From the list of common names for the family, I suspect it would be easy to conclude that the family produces a fair number of edible and otherwise useful cultivated species. The main economic species produce edible, fleshy fruit today. But this has not always been true and is certainly NOT true of coyote melon and most other wild members of the family today. The flesh of coyote melon is extremely bitter and if one is tempted to try to eat it, it would act as an extreme emetic. That is, it would rapidly be expelled from both ends.
So what’s the link between inedible and/or poisonous wild cucurbits of today with the edible cucurbits listed above? It is best summed up by a quote from a November 20, 2015 paper by A’ndrea Elyse Messer titled “Loss of Mastodons Aided Domestication of Pumpkins, Squash.” I actually heard (or read) about the article around Thanksgiving and decided to look it up on the Web. The quote that caught my interest was: If Pleistocene megafauna – mastodons, mammoths, giant sloths and others – had not become extinct, humans might not be eating pumpkin pie and squash for the holidays, according to an international team of anthropologists.
The article indicates that most wild cucurbits are bitter and that smaller organisms (and humans) tend to avoid trying to eat the fruit. It then notes that large mammals, such as the mastodon, have fewer bitter taste buds in their mouths so eating cucurbits shouldn’t have been a problem. The authors note that they could deduce that the mastodons were eating cucurbits because when and wherever they examined fossil mastodon dung it contained cucurbit seeds. Since the only way cucurbit seeds could get into dung is by being eaten, they concluded cucurbits were an important food source for them. Being huge animals, mastodons had to migrate over wide distances so they also concluded mastodons were major dispersers of cucurbit seeds. The researchers also found that the DNA they recovered from the seeds in the dung was more similar to wild cucurbits of today than to cultivated edible ones. Therefore it’s logical that the ancestors of the edible cucurbits were bitter.
What killed off the mastodons? A recent book titled, The Sixth Extinction, gives a possible clue. It turns out that large animals live in a very tight balance with their environment and the regular sustained loss of even a few key animals would lead to extinction in a relatively short time (a few thousand years). Early humans coexisted with the last of the mastodons. Early human hunters probably preferred to kill the biggest and healthiest animals as hunters still do today. This would mean they would have taken the breeding animals of a family or herd. When a parent is killed, often the rest of their family dies as well. So even with very modest losses of a few key animals a year, the book indicates it would lead to a slow extinction in a few thousand years.
Mastodons and the other large mammals died out over ten thousand years ago. So why do we have edible cucurbits today? The article indicates that early peoples didn’t use fresh cucurbit fruits for food, but waited until they were dry and hollow and used them for containers, noise makers (rattles) and/or fish floats. Although some species’ seeds (e.g., coyote melon) are edible when totally mature, at least some of their seeds would have ended up in their disturbed, highly nitrogenous trash heaps. So people took over from the mastodons as major seed dispersers. So cucurbits would have been become common around early human settlements. Since a bitter compound is often poisonous in large uncontrolled amounts, but medicinal in small, regulated amounts, it can be assumed that early peoples used fleshy immature fruits as medicine. It doesn’t seem to me to be a great stretch to assume enough genetic variability in early cucurbits so that some would have been less bitter. These would be selectively utilized by early people, probably the wives and mothers.
By the time the mastodons were gone, early peoples would have been planting various cucurbits around their settlements. Once there, they would have been selected to be less and less bitter until we have the edible squash and pumpkins we enjoy today. So next Thanksgiving, remember to thank the mastodons and other large extinct mammals for your pumpkin pie. One final thought, pumpkins and squash were domesticated in the new world and in all likely hood the jack-o-lantern pumpkin was one of the few major crops domesticated within the lower 48 states. Personally, I find coyote melon to be best (and safely) enjoyed as we find it, growing in nature.
Dr. Neil Havlik was recognized with the 2015 Hoover Award for his contributions to appreciation and preservation of the San Luis Obispo native flora. The honor, named for Dr. Robert Hoover, was presented to an appreciative Neil Havlik at the annual Banquet on January 23. Prior recipients meet yearly to select an honoree judged for their accomplishments in education, conservation and chapter support.
Dr. Havlik served as San Luis Obispo City Natural Resources Manager from 1996 until his retirement in 2012. In that role, he oversaw the creation of the city greenbelt. He was instrumental in the acquisition of key parcels, protection of other private parcels, the expansion of the greenbelt trail systems, and was the guiding force behind the joint publication
(with our chapter) of the immensely popular Wildflowers of San Luis Obispo guidebook. His role in protecting Chorro Creek bog thistle populations within the greenbelt led to a 2015 special award from the US Fish and Wildlife Service.
Neil majored in Biology at Cal Poly San Luis Obispo, graduating cum laude in June 1968. At our banquet, Dr. Havlik recounted how honored he was to have studied under the late Robert Hoover. He then attended the graduate program in Botany at UC Santa Barbara from January 1969 to June 1971, earning a Master of Science degree in Botany. In 1978, Neil went back to school, seeking a Doctorate in the interdisciplinary Wildland Resource Science program at UC Berkeley. He earned his doctorate in that field in June 1984.
Havlik held a variety of positions with the East Bay Regional Park District in Oakland for fifteen years, involved in land use planning, environmental impact analysis and mitigation, natural resource management, property management, and land acquisition. In 1987 he became the first Executive Director for a non-profit land trust headquartered in Fairfield, California (Solano County in the lower Sacramento delta).
Since retirement, Dr. Havlik has contributed greatly to developing a local Carrizo Plains Conservancy initiative, a special purpose land trust targeted on bringing more property under protection in our Carrizo region. Neil Havlik also serves on the board of the Coastal San Luis Resources Conservation District. The RCD projects play an essential role in furthering preservation of our rural landscape, quietly enlisting landowners in vital protection projects.
Please share your appreciation of the Neil’s wonderful contributions to our county and its flowers.
