Natural Resources DataBase

What Is the Natural Resources DataBase?

The Natural Resources DataBase is a compilation of observations of flora and fauna made at open space and nature preserves and parks in the greater San Francisco Bay Area. The database can be searched for available data on flora, mammals, birds, reptiles, amphibians and fishes seen at one or more preserves. The database was designed and implemented by Dennis H. Smith, who also entered and maintains the data. Bill Korbholz adapted the database for Internet use and designed and implemented the web interface. The system was a popular source of lists for use in the field, and provided users with a wide variety of options -- including checklists, plant lists and more.

Although many of the preserves represented in the NRDB are a part of the Midpeninsula Regional Open Space District, MROSD is not affiliated with the NRDB nor is the District responsible for the maintenance, quality, or accuracy of data represented by the NRDB. Collection of specimens on preserves represented in the NRDB requires special permission. Contact the managing agency for more information.

As of its last update on 3/31/2020, the database contained information on 4,510 plant and animal species found on 238 preserves within the greater San Francisco Bay Area. There have been 95,155 sightings recorded to date. Plant lists from NRDB have been copied to PlantID.net and Calflora.

Accessing NRDB lists on PlantID.net

All of the plant lists from nrdb.org are available on PlantID.net under Local Plant ID Lists. Lists from nrdb.org will include "List Source: NRDB.org" under the list name.

Accessing NRDB Observations at Calflora

Tens of thousands of NRDB observations have been transferred to Calflora. The focus of the NRDB is what species are observed at named preserves. The focus of Calflora is where named species have been observed. Calflora provides a mechanism for getting a plant list for a given preserve, but there are currently some caveats. Every species in Calflora is accompanied by observation records. Because NRDB data were entered into Calflora as checklists, you must check the 'include surveys/checklists' box on the Observation or Observation Hotline page. NRDB observations will appear withObserver = Staff, and Source = Natural Resources Database - www.nrdb.org.

Botanizing in the State of Jefferson July, 2007

On June 30th, nearly 30 CNPS members made a seven hour voyage to the area of far northern California that many consider to be the heart of the State of Jefferson. What follows is a summary of where we went and what we saw.

Situated right on the wild and scenic Klamath River, Sarah Totten campground was all ours, and offered a wonderful place for us to call Home Sweet Temporary Home. On Sunday July 1st, we caravaned to Cook & Green Pass via Saeid Creek Rd., making several stops on our way up. At our first stop, sharp eyes spotted an interesting saprophytic plant growing in the forest duff: Monotropa hypopythis or pinesap, and this was a first time sighting for most in the group. As we continued uphill, we found many other interesting and showy plants, including some that were being dug up by poachers! At the top, we explored the Pacific Crest Trail as it heads east of Cook & Green, and  got a taste of the rich flora of the region and its relationship to the geology.

Monday was Calochortus day, and we traveled to three very different locations finding all three species we were seeking in nice bloom: C. persistens high up on Gunsight Ridge just west of Yreka; C. greenei just over the border into Oregon; and C. macrocarpus in a wide valley north of Mt. Shasta.

Day three saw a return to Cook & Green, this time on the PCT west of the pass towards Red Buttes. We encountered many species not seen on the other side of the pass, including a seep with Cypripedium californicum, the California lady-slipper orchid. The top of our journey to Bee Camp opened up to an area of stunning vistas and a different flora, as the local botany closely follows the local geology and microclimate.

The next day was a trip to Alex Hole, a northeast-facing cirque situated at the shoulder of Coundry Mountain. We found a stunning array of species to occur in and around this glacially-carved bowl, including choice plants from genera Lewisia, Erythonium, and Polemonium, along with several orchid species. This is also the only place we encountered melting snow. I think...

We moved camp south for the rest of the trip, to yet another paradise situated on the summit of Scott Mountain Pass, south of Etna on Hwy. 3. This campground adjacent to large meadows with seeps and fens surrounded by rich woodlands provided ample opportunity for the botanically inclined to lose themselves in the identification and appreciation of such a diversity of species.

Jefferson, we shall return.

Sonora Pass Carcamp Trip Report (Aug 1-3, 2008)

by Carolyn Dorsch

Eighteen people, including trip leaders Stella Yang and Carolyn Dorsch headed up to the Sierras the first weekend of August.  We camped off of Hwy 120, at 6,200 feet, near the Clark Fork of the Stanislaus River.  The first day we stayed in the “lowlands,” and explored along the Clark Fork meadow and the Column of the Giants. 

Day Two found us up near the top of Hwy 120, just a little west of Sonora Pass.  We spent the day hiking up to St. Mary’s Pass (10,100 feet).  The walk was steadily uphill, but with wildflowers all along the way, low 70s temperature, and nice breezes, the 1,200 foot climb from the trailhead was quite manageable.  Along the way, and at the top of the pass we found many high-elevation flora blooming, including the following:  Pursh’s wooly-pod (Astragalus purshii), Buckwheat (Eriogonum ovalifolium), Sierra Claytonia (Claytonia nevadensis), and Arctic Willow (Salix arctica).  In fruit were two anemones: A. occidentalis and A. drummondii.  All together, it was about a three-mile round trip.  A couple people took the challenge offered by the mountains, and continued their hike up to Stanislaus Peak (11,233 feet) before rejoining the group back at the trailhead in the late afternoon.

Day Three, as a final stop before heading home, we drove down Herring Creek Road.  While it can be stunning in June (elevation around 7,000 feet), we had to work harder to find the flowers.  Following the water, we came across beautiful colonies of Alpine Lily (Lilium parvum) near Herring Creek. The trip was capped off with a short visit along the Trail of the Gargoyles, where we could admire the amazing geologic formations.  Plans are already in motion for another trip up to the Sonora Pass area. 

Late June/early July is the best time to see the flowers at the 6-7,000 feet elevation, but there is plenty to see in early August, so long as you go to the higher elevations. Look for this trip’s highlights at a Member’s Night meeting later in the year!

CNPS Santa Clara Valley Chapter Field Trips

CNPS Santa Clara Valley Chapter Field Trips

IMG 7822 dee stella ken pinnacles 640pxChapter field trips are free and open to the public.  Field trips are oriented to conservation, protection and enjoyment of California native plants and wildlife.  A list of past field trips and reports can be found here.

Many other upcoming chapter activities are listed in the Blazing StarYou can also find many of our chapter field trips and other activities on our Meetup Group.  Signing up on Meetup allows the trip leaders to send notifications in case of changes or cancellations.

In our region it is important to be prepared for hiking on rugged and steep terrain, wide temperature ranges and rapidly changing conditions at any time of year. Our hikes are often slow with many stops and standing around for long periods. All participants should wear sturdy footwear and carry sufficient water, sun protection, food, clothing layers, personal first aid and other supplies you may need. Also bring hand lens and binoculars for viewing plants and fauna.

Cell service is mainly restricted to cities and major highways. On your way to an outing do not rely solely on your phone. If you have any questions about your ability to participate in a particular field trip, please contact the trip leader in advance.

 


RSVPs on Meetup

We are trying a new approach to RSVPs on Meetup. We will announce the events when they are posted. This will let folks note the trip and date. The RSVPs will open up one week before the event. If you are signed up for Meetup announcements, you will receive a second notice when the RSVPs open up. Our hope is that this will reduce the number of no shows as folks will be making RSVPs closer to the trip dates. We apologize to those for whom this creates an inconvenience.

FEBRUARY 2024

Sat Feb 10  10:00am – 2:00pm  Dirca Walk at San Francisco Peninsula Watershed  (San Mateo County)
Join Chapter Rare Plant Chair Don Thomas to see the rare Western leatherwood (Dirca occidentalis) in the Crystal Springs Watershed along the Sawyer Camp Trail.  This will be an easy slow-paced walk of about four miles round-trip, starting at the trailhead on Hillcrest and Highway 280, with a stop for lunch.

Dirca is one of the first plants to bloom each year, revealing its bright yellow hanging flowers from its bare winter branches.  We will also have a chance to see other early blooming plants, such as hound’s tongue (Adelinia grandis) and trillium (Trillium chloropetalum).

Dirca is a rare paleoendemic plant native only to the San Francisco Bay Area, ranked by CNPS as 1B.2.  (Read more about CNPS rare plant ranks at www.cnps.org/rare-plants/california-rare-plant-ranks.)

An optional additional short walk along the Sawyer Camp Trail will be to the Jepson Laurel.  This was at one time the largest bay tree in California, but it has been declining for many years.  Many large branches have died and broken off the tree over time, so it has been dethroned as the largest in the state.

Wear warm clothes and bring water and lunch.

RSVP is required to join us for the hike.  Space is limited.  No drop-ins please.  To complete the required RSVP, please visit our Chapter’s Meetup page at https://www.meetup.com/California-Native-Plant-Society-Santa-Clara-Valley-Chapter/.

Sun Feb 16  10:00am – 1:00pm  Dirca Walk at Jasper Ridge  (Woodside)

This is an activity for CNPS Members. Everyone will go on the waitlist, and verified members will be admitted until the trip is full. If you are not a current member, you can join at https://cnps.org/join.

Join Vivian Neou for another chance to see the rare Western leatherwood (Dirca occidentalis), this time at Jasper Ridge Biological Preserve (JRBP).  This will be a slow-paced walk of about four miles to also see other plants that may be blooming.

JRBP is home to some of the largest stands of Dirca in the area.  Participants will have an opportunity to see several stands of Dirca, as well as to learn about ongoing research on Dirca.

JRBP is a private preserve and is not open to the public. The trip is limited to CNPS  members only and eight participants.  No drop-ins.  To complete the required RSVP, please visit our Chapter’s Meetup page at https://www.meetup.com/California-Native-Plant-Society-Santa-Clara-Valley-Chapter/.  Details will be sent to registered participants.

MAY 2023

Sun - May 7 10am-3pm Sierra Azul Open Space (San Jose)

Woods Trail Through a Gardener’s Eye: Locally Native Plants for Bay Area Gardens

With an Option for a Shorter Hike Ending at 12:30pm

California’s plant diversity is among the greatest in the world and many of our native plants are suitable for landscaping. It is easy to see why: locally native plants have evolved in local soils and microclimates and fit perfectly in Bay Area gardens.

Join Arvind Kumar, Ashok Jethanandani, Stephanie Morris and Vicki Silvas-Young on this walk along Woods Trail to learn about the native plants local to our area. Arvind and Ashok are home gardeners in San Jose with a special interest in local natives. Stephanie is a landscape architect and past Gardening with Natives Committee chair. Vicki leads many field trips for the Chapter, Santa Clara Valley Audubon Society and Open Space Authority.

This hike is particularly focused on native plants on the trail that work well in gardens (and are generally available at native plant nurseries). It is not a detailed plant taxonomy trip. Observing the microclimates, companions and mature sizes of locally native plants can be a fantastic way to learn more about native plant gardening.

This contour trail of the Sierra Azul range has gradual ascents/descents, and the north-facing aspect keeps it cool even on warm days. The plants are flourishing after this season’s extended rainfall, and many may still be blooming. Plan future additions to your garden armed with the knowledge of the many attractive shrubs, subshrubs, perennials, and annuals that grow naturally here.

The full-length walk is 5.6 miles (out and back), with 330 ft of elevation gain/loss. Dress in layers, appropriately for the weather. Bring a sack lunch and plenty of fluids.

For those wishing to take a shorter hike, we will also leave with the main group at 10am but we will turn back earlier and skip the lunch break, returning to the parking lot by about 12:30pm. The shorter trip is about 2.5 miles and is also perfect for families! Bring water and bring snacks if desired.

Directions: Take Hwy 85 to San Jose. Take the Camden Ave. exit and go south. In 1.8 mi, turn right on Hicks Rd. After 6.3 miles, turn right on Mt Umunhum Rd. The parking lot is immediately on the right. In Google maps drive to pin “Sierra Azul Parking Lot at Jacques Ridge.”

We will meet in the lot at 10am and plan to return by 3 pm. (If the lot is full, find parking on the opposite side of Hicks Rd. in Almaden Quicksilver Park’s Wood Road lot and walk back.)

RSVP is required to join us for the walk. Space is limited. No drop-ins please. To register, please visit the Meetup page at https://www.meetup.com/California-Native-Plant-Society-Santa-Clara-Valley-Chapter/

Anza Borrego State Park - March 6 - 13, 2016

By Dee Wong, Field Trip Chair

bighorn sheep anza borrego lohseCo-leaders Patricia Evans and Joe Cernac took 17 hearty souls (including CNPS fellow Sally Casey, age 94) on a trip to the desert, despite forecasts of rain. After arriving in Anza Borrego on Sunday March 6, the trip started in the rain Monday with a stop at the visitor center. Two days of sunny hiking followed in Palm Canyon and Culp Valley. Many of the highlights were seeing the desert peach, desert apricot, and desert almond all on the same day. We also saw five bighorn sheep which the state park is partially named after, Borrego, and hundreds if not thousands of sphinx moth caterpillars of various instars (molting phases) devouring the brown-eyed primrose and sand verbenas. Dee Wong even saw one that was digging a hole in preparation for pupating.

Stile Ranch Hike #2, May 10, 2015

By Dee Wong, Field Trip Chair

asclepias-fascicularis-narrow-leaved-milkweed-closeHike #2 was to see the progression of drought effecting Stile Ranch. There were 11 attendees including the co-leaders Stella Yang and Dee Wong, and Ken Himes as sweep. As the weather heated up without much winter rains, the grasslands along the trail had already started drying out and turning gold and silvery in color. The native grasses such as Elymus glauca, Melica californica and Melica torreyana had begun to set seeds. With most spring wildflowers finished flowering, the summer flowering plants that were in bud (during hike #1) were now flowering, such as the Monardella douglasii, Streptanthus glandulosus var. glandulosus.
