Name:
Nassella pulchra - Brodiaea elegans - Plagiobothrys nothofulvus Native Grassland Macrogroup
Reference:
NatureServe Biotics 2019
Description:
This macrogroup includes the now relictual native perennial grasslands, native annual grasslands and native annual forb meadows of California. Characteristic native plant species include a dominance by native, cool-season bunchgrasses <i>Agoseris heterophylla, Aristida</i> spp., <i>Bromus carinatus, Elymus glaucus, Festuca californica, Festuca idahoensis, Leymus condensatus, Melica californica, Nassella cernua, Nassella lepida, Nassella pulchra</i>, and <i>Poa secunda</i>. Native annual species include <i>Amsinckia</i> spp., <i>Eschscholzia</i> spp., <i>Lotus unifoliolatus, Lupinus</i> spp., <i>Plagiobothrys nothofulvus, Trifolium variegatum</i>, and <i>Vulpia microstachys</i>. Occurrences often have high native species richness, though many now have significant abundance of non-native species. Historically, native perennial grasslands were common among oak savanna and woodland and probably experienced similar frequent fire regimes. Today they are limited to small relictual, remnant and restored stands. These communities are best represented on xeric to mesic ultramafic sites where alien annual grasses are less well-adapted. This macrogroup occurs in Mediterranean California from 10-1200 m (30-3600 feet) elevation, with cool, wet winters and hot, dry summers, receiving on average 50 cm (range 25-100 cm) of precipitation per year, mainly as winter rain. It is found with fine-textured soils, moist or even waterlogged in winter, but very dry in summer.
