Cattle Grazing Impacts on Annual Forbs and Vegetation Composition of Mesic Grasslands in California
Abstract: Livestock grazing represents a major human alteration of natural disturbance regimes in grasslands throughout the world, and its impacts on plant communities have been highly debated. We…
Site-specific responses of native and exotic species to disturbances in a mesic grassland community
Treatment response of some plant guilds differed among sites, highlighting the importance of replicating experiments at several sites before recommending conservation manage- ment practices.
Disturbance, Resources, and Exotic Plant Invasion: Gap Size Effects in a Redwood Forest
The view that both physical disturbance and increased availability of scarce resources contribute to a community's susceptibility to invasion is supported and a linear relationship between the size of logging gaps and the magnitude of exotic species invasion is suggested.
Seed banks in plant conservation: Case study of Santa Cruz tarplant restoration
Effect of Seed Source, Topsoil Removal, and Plant Neighbor Removal on Restoring California Coastal Prairies
The results suggest that removing topsoil prior to transplanting seedlings grown from local seeds is the most promising method to reintroduce D. californica into degraded California coastal prairies.
Reintroduction of Nassella pulchra to California coastal grasslands: Effects of topsoil removal, plant neighbour removal and grazing
The results suggest that seeding after topsoil has been removed is a promising method to reintroduce N. pulchra to highly degraded sites where there is little to no native seed bank.
Challenges to Introducing and Managing Disturbance Regimes for Holocarpha macradenia, an Endangered Annual Grassland Forb

This relatively well-studied species of concern was unsuccessful in introducing to apparently suitable habitat at multiple sites in multiple years, which suggests that translocating rare plant populations to mitigate for habitat destruction is an expensive and highly uncertain endeavor.
7. Northern Coastal Scrub And Coastal Prairie
Northern coastal scrub and coastal prairie exist in a continuum of herbaceous to dense woody shrub cover wherever the cooling influence of the Pacific Ocean moderates summer drought (Fig. 7.1) from…
Manipulating disturbance regimes and seeding to restore mesic Mediterranean grasslands
Managing disturbance regimes alone is insufficient to restore native species guilds in highly-invaded grasslands and seeding native species has highly variable success.
