IN THE FIELD: Corte Madera Mountain

By Tom Oberbauer

Back in January of 1978, I hiked up onto Corte Madera Mountain with a friend, Tom Scott (now with UC Berkeley and UC Riverside), who had been studying Golden Eagles in San Diego County. Bald Eagles were wintering at Corte Madera Lake. After postponing the hike due to rain, that was a good rain season, we drove out to Corte Madera Lake, which was accessible because Tom Scott had a key, and we hiked up the north side of Corte Madera Mountain on a little used trail. The trail climbed through a woodland of mostly coast live oak (Quercus agrifolia), but also Coulter pine (Pinus coulteri), as well as Jeffrey pine (Pinus jeffreyi). It was foggy going up and the view was obscured.

In The Field: The New Santa Fe Valley Trail

By Jürgen Schrenk

Recently, the new Santa Fe Valley Trail, connecting the San Dieguito River Park’s Del Dios Gorge Trail with the Lusardi Creek Preserve, was opened to the public. The beginning of the trail took us through fields of Menzies’ Goldenbush (Isocoma menziesii var. menziesii).

The Desert a Month after Monsoonal Rains

By Jürgen Schrenk

After yet another week of waiting for the temps to go down watching our Monarch production and limiting our walks to local parks, I was worried that I might completely miss the monsoonal “spring” in the desert. So, I went on a quick drive along S-2

CNPS-SD Helps With Rare Plant Surveys

By Justin Daniel, Vice President, Rare Plants Co-chair

With vaccinations allowing more contact outdoors and a workload a year behind, it's been a busy time a few of us to help some of our fantastic environmental conservancy organizations around San Diego County by assisting them in their rare plant surveys. The following are glimpses into some of the recent surveys. Come along for the ride and reach out to support our partners, too!

The Mount Laguna Surprise

By Tom Oberbauer

…The next week, I drove up and hiked to the location I visited in December and sure enough, the display of Platystemon californica (above) was pretty amazing. Sheets of color extended across the slopes leading into the center of the meadow. I spent some time attempting to photograph and create video of the breeze gently shaking the small flowers. From this location, the view of the meadow ranges across its full length, extending more than three miles in the distance to the south. Laguna Lake also contained a good level of water reflecting the blue sky, apparently left over from the previous two good rainfall seasons. I attempted to capture the view of the flowers with the lake and end of the meadow in the distance. The breeze and the movement of the flowers in this manner always reminds me of when I was a child and my family visited Estes Park in Colorado and we observed alpine wildflowers…

Vegetation vs. Plant Communities, and Why It Matters

,

By Frank Landis, CNPS-SD Conservation Committee Chair

Just to be different, I thought I’d go back to my roots as a plant community ecologist and explain why I dislike that particular label so much. I will be going into what the words plant community and vegetation mean, and why vegetation community is such an ugly and ill-thought neologism.

First, vegetation: it simply means all the plants in a defined area. That’s what Julie Evens (my former lab mate and now CNPS Fellow) maps for CNPS, and I’m glad she does. Plant community also means all the plants in an area, but it comes attached to a rather problematic and disproved theory that I will describe below.

The third term I will add is ecosystem, which means all the organisms in a particular area, plus their abiotic environment. This may seem to be a non-sequitur, but if this is new to you,you’re probably going to raise one of some very commonobjections. Most of those objections actually refer to ecosystems, not plant communities. Please keep this in mind. Plant community and vegetation refer only to plants.
