Intervention effect Grass specific herbicide controlled exotic annual grasses and promoted seeded shrub establishment.
Observation No native seedbank remained after about 30 years as annual grassland.
Observation Only seeded shrubs and one native summer annual germinated.
Intervention effect Green waste mulch caused short term nitrogen immobilization.
Intervention effect Green waste mulch did not increase native shrub establishment.
Intervention effect Shrub seeding succeeded in a wet year.

Observation An accidental spring fire did not burn first year shrubs, while adjacent annual grass plots burned.
Observation Established shrubs continued excluding exotic grasses into a second growing season.

JOAN M. THURSTON Weed Research 1962. doi:10.1111/j.1365-3180.1962.tb00199.x

Other claims from this paper (12)

Association Wild oats were controlled by a dense crop of an autumn-sown cereal.
Association The effectiveness of cereal crops against wild oats depended on crop density when the wild oats germinated in spring.
Association The crop genus was unimportant for the effectiveness against wild oats, provided the crop grew well on the site.
Intervention effect Winter wheat and winter rye were equally effective in controlling wild oats.
Intervention effect Wild oats grew much less vigorously in a light barley crop than on fallow plots.
Intervention effect The heaviest crop did not completely suppress wild oats.
Mechanism The crop affected wild oats mainly by decreasing seedling growth.
Mechanism Some wild oat seeds may have remained dormant under winter wheat and winter rye, perhaps because the crops decreased soil moisture.
Intervention effect Nitrogenous fertilizer increased the weight of both crops and wild oats.
Association Barley was more severely affected by soil acidity than wild oats.
Intervention effect On acid areas of barley plots, wild oats were larger than where the pH was higher.
Intervention effect In wheat and rye scarcely affected by soil acidity, the size of wild oat plants was unaffected by soil pH.
