We used paired burned and mature sites in chamise chaparral, mixed chaparral and coastal sage scrub (California), and rosemary scrub, sand pine scrub and sand-hill (Florida), to test whether (i) patterns of pre-fire and post-fire seedling recruitment are more similar between communities within a region than between regions, and (ii) post-fire. 1. Introduction. Mediterranean-type semi-arid shrublands, including chaparral and coastal sage, are distributed throughout cismontane California, northern Baja California Mexico, and south-central Arizona, inhabiting elevations that vary from sea level to over m, temperature regimes that range from 0–10°C in winter to 15–45°C in summer, and precipitation regimes that vary Cited by:

Dominant shrub species of coastal sage scrub in coastal southern California are able to produce shoots from their base on a continual basis in the absence of fire or other major defoliation. As a result, each shrub becomes a population of mixed-aged branches (ramets) and extends its duration in the canopy beyond the age of any of its above-ground phytomass.

Facelli. Microdisturbances in old fields and forests: implications for woody seedling establishment. Coastal beach and dune habitats, coastal and interior sage scrub, chaparral, woodlands, grasslands, riparian woodlands, and wetlands all contribute unique plant assemblages to Southern California.

In addition to discussing each of these areas in depth, this book also emphasizes ecological factors such as drought, seasonal temperatures, and fire /5(9).

Californian coastal sage scrub has floristically distinct subassociations with sharp boundaries in the Santa Monica Mountains. This mesoscale biogeographic pattern has been variously attributed to the timing and pattern of fire and to differences in the moisture availability on sites.

Arizona: Red brome is an invader of Arizona desert scrub [ 59 ]. It is also an invasive understory species of mature mesquite bosques (Prosopis spp.), which were historically open with a ground cover of saltbushes or annual and perennial native grasses and forbs [ 23 ].

Coastal sage scrub is distributed along the coast and semiarid inland regions of southern California (Riordan and Rundel, ). The coastal sage scrub community is dominated by drought-deciduous short shrubs averaging 1–2 m high that drop leaves during dry summer months as soil water availability decreases, and produce new leaves at the Cited by: Postfire brittlebush densities for east and west exposures years after a June coastal sage scrub fire were 79 to percent of prefire densities on east, south, and west exposures.

Coastal sage scrub in the Santa Monica Mountains regenerates following fire primarily through resprouting from root crowns. Dominant shrubs are variable in post-fire resprout and seedling regeneration and also in continual seedling establishment.

Such differential reproductive success in both the immediate post-fire environment and in the succeeding years should result in a. Post-fire diversity patterns in two subassociations of Californian coastal sage scrub O'Leary, John F.

Starr Ranch has operated as a preserve of southern California wildlands since Our acres encompass the unique mosaics of mediterranean climate habitats that were once, before the spread of urbanization, typical of southern Californian landscapes: coastal sage scrub, grasslands (native perennial bunchgrass and exotic annual), oak woodland, chaparral.

The California chaparral and woodlands ecoregion, of the Mediterranean forests, woodlands, and scrub biome, has three sub-ecoregions with ecosystem—plant community subdivisions. California coastal sage and chaparral: In coastal Southern California and northwestern coastal Baja California, as well as all of the Channel Islands off California and Guadalupe Island .In Chapter 2, Ecological History, the authors discussed the evolution of the California grassland, oak-woodlands, chaparral and coastal sage scrub.

The purpose of this chapter is to give the reader a broad overview of annual rangeland vegetation and how it may change in response to common disturbances such as invasion, fire and grazing.
