The germinable soil seed bank of a grassy Eucalyptus populnea F.Muell, open woodland was investigated in relationship to distance from water (away from a bore-drain) on North Yancho Station, near Bollon in southern semi-arid Queensland. The germinable soil seed bank was both diverse and abundant, 69 taxa of seedlings being identified to species and 2 more to genus. A mean density of 13 207 ± 4160 seeds m-2 was recorded, with over 80% of the seed being from the annual forbs Crassula sieberana (Schultes & J.H.Shultes) Druce, Wahlenbergia tumidifructa P.J.Smith and Dysphania gomulifera (Nees) Paul G.Wilson. Most common species showed spatial variation in their germinable seed density with relation to distance from water, resembling the patterns previously reported by other authors for standing vegetation under stocking pressure gradients.

Forage Production

Abstract Non-native plant invasions can have devastating effects on native plant communities; conversely management efforts can have non-target and deleterious impacts on desirable plants. In the arid sagebrush steppe rangelands of the western United States, non-native winter annual species affect forage production and biodiversity. One method proposed to control these species is to suppress the soil seed bank using the pre-emergent herbicide indaziflam. Our goal was to evaluate the efficacy of indaziflam to control non-native annual mustards (Alyssum spp.) and to understand potential non-target effects of management on the diverse mountain sagebrush steppe plant communities within Yellowstone National Park. Six sites were established along an elevation gradient (1615 – 2437m), each with high and low Alyssum spp. infestations. We applied 63g ai ha−1 of indaziflam in late summer of 2018 and evaluated plant community cover in situ for two years after treatment, and emergence of forb species from the soil seed bank ex situ. Indaziflam was highly effective at controlling Alyssum spp. emergence for two years. Richness and Shannon’s diversity of the non-target plant community were significantly lower in sprayed plots than the control, and both decreased along the elevation gradient. These reductions were due to a decrease in perennial forbs and native annual forbs in the sprayed plots; perennial graminoids were not affected. Overall, the above ground and seed bank community composition was negatively impacted by indaziflam, and these effects were strongest for the native annual forbs that rely on annual regeneration from the seed bank. The effects of this herbicide to the non-target community should be evaluated beyond the length of our study time, however we conclude indaziflam should likely be reserved for use in areas that are severely invaded and have seed banks that are comprised of non-desirable species rather than diverse, native mountain sagebrush communities.

AbstractThe physically dormant seeds ofIpomoea lacunosaand ofI. hederaceaundergo sensitivity cycling (insensitive ↔  sensitive) to dormancy-breaking treatment. Sensitivity cycling is important to seeds with physical dormancy in sensing appropriate environmental conditions for germination. Seed vigour is also important to seedling establishment, but no study has compared changes in vigour (or not) with changes in sensitivity. This study was conducted to determine the relationship between sensitivity cycling and seed vigour inI. lacunosaandI. hederacea. The seed moisture contents of insensitive and sensitive seeds ofI. lacunosaand of sensitive seeds ofI. hederaceawere measured, and several vigour tests were performed. Vigour of sensitive seeds ofI. lacunosadecreased more rapidly than that of insensitive seeds. No significant change in vigour was observed in either permeable or impermeable seeds ofI. hederacea. We conclude that sensitivity cycling to physical dormancy break is important in maintaining vigour ofI. lacunosaseeds in the soil seed-bank.

Seed banks are important for understanding vegetation dynamics and habitat regeneration potential. Biancana badlands are vanishing landscapes where recurring and non-recurring management has been advocated to restore vegetation. Here, we investigated germinable seed bank structure and composition of a biancana badland in central Italy and evaluated the relationship between the standing vegetation and soil seed bank. We identified four land cover classes in five biancana badlands of Tuscany (central Italy) and collected data from 132 vegetation plots and 660 soil cores. We recorded 117 species in the standing vegetation. The seedlings that emerged from the soil samples, mostly annual species, numbered 183 and belonged to 31 taxa (392.5 seedlings/m−2 on average across the four land cover classes). Standing vegetation showed an aggregated spatial pattern with distinct communities while the seed bank showed a less aggregated spatial pattern. The similarity between the seed bank and standing vegetation was low. In contrast with the features generally found for disturbed and pioneer communities, but in line with seed bank characteristics of other badlands, the seed bank was particularly poor in species.
