JS Ranch
|
| Location Narrative |
This plot is located on a gentle north-facing slope, 150 m west of Whitmore Rd, on the north end of the JS Ranch property, surrounded by barely leafing-out blue oak woodland. This annual grass-dominated stand, with high cover of Zigadenus fremontii, extends another 60 m to the west in an adjacent opening of tree canopy. The soil substrate is very heavy clay, and there is a thick thatch layer (most likely from Taeniatherum) in the stand.; This site is heavily grazed, but not as much as surrounding areas, maybe due to toxicity of Zigadenus fremontii, which the cattle do not eat.
