Soil seed banks that persist after a fire are important in fire-prone habitats as they minimise the risk of decline or local extinction in plants, should the fire-free interval be less than the primary juvenile periods of the species. In two common woody plant genera (Acacia and Grevillea) in southeastern Australia, we examined the size and location of the residual seed bank after fire across areas of varying seedling densities at three locations in comparison to the distribution of seeds in… 
The effect of recent fire history on the abundance and viability of large seeds in the soil of sclerophyll forest in Tasmania, Australia
There are few data on the effects of recent fire history on the composition of soil seed banks in sclerophyll forest communities. We predicted that the abundance and viability of soil-stored seeds
Seed traits determine species' responses to fire under varying soil heating scenarios
The authors' data demonstrate that seeds exhibit variation in their response to soil heating and capacity to emerge from depth, with three distinct functional responses amongst their study species, which enable persistence through, and recruitment following, fire.
Seed dynamics of two fire-dependent Geranium species in the boreal forest of southeastern Sweden
Analysis of critical life-history variables for two rare fire-dependent annual Geranium species in southern Sweden shows that successful management of these species depend on deep-burning prescribed fire, which can only result after severe fire suppression.
The dynamics of three shrub species in a fire-prone temperate savanna: the interplay between the seed bank, seed rain and fire regime
The crucial roles of the soil seed bank and seed rain in regeneration are revealed, providing vital information for the development of appropriate management practices to control populations of shrub species with different regeneration strategies in South American temperate savannas.
Seed size an important factor for the germination response of legume seeds subjected to simulated post-fire soil temperatures
It is demonstrated that small-seeded species are able to germinate across a range of temperatures and can have dormancy broken either during the passage of a fire, or after fire from increased solar radiation, potentially resulting in the decline of the post-fire residual soil seed bank.
Post-Fire Changes of Soil Seed Banks in the Early Successional Stage of Pine Forest
Germination of Calluna seedlings from the burnt soil seed banks in several times higher numbers than from unburnt soil seed Banks may suggest that heat from the fire promotes a loss of dormancy in the heather seeds.
Soil temperatures during autumn prescribed burning: implications for the germination of fire responsive species?
Prescribed fire is a widely applied management tool in native forests. There have been concerns raised about the ecological impacts of prescribed fire on native flora. One aspect of the debate is the
Fire severity drives variation in post-fire recruitment and residual seed bank size of Acacia species
It is found that high fire severity may impact on the ability of a species to persist in response to a subsequent short fire interval, and fire management for maintaining biodiversity needs to consider other key aspects of the fire regime, including severity and season.
Fire‐related cues and germination from the soil seed bank of senescent remnants of mallee vegetation on Eastern Kangaroo Island
It is illustrated that the application of fire-related treatments to soil seed banks in controlled glasshouse conditions can stimulate the recruitment of native species, including several species of conservation concern.


Distribution of the Soil Seedbank and Influence of Fire on Seedling Emergence in Acacia saligna Growing on the Central Coast of New South Wales
The distribution of seed in the soil and its response to simulated fires were examined in a population of Acacia saligna (Labill.) H.L.Wendl. on the central coast of New South Wales (NSW). Soil seed
Seed banks, fire season, safe sites and seedling recruitment in five co-occurring Banksia species
Quantity of seed stored in the canopy of 5 co-occurring Banksia species varied by nearly 2 orders of magnitude. The 3 species which resprout vegetatively after fire, produced less seeds and retained
Patterns in longevity of soil seedbanks in fire-prone communities of south-eastern Australia.
Examination of seed longevity patterns in 12 shrub and two graminoid species in fire-prone habitats around Sydney, south-eastern Australia found that maintenance of a soil seedbank is predicted to be dependent on continual inputs of seeds locally or dispersal of seeds from other sites.
Fire and flood: Soil‐stored seed bank and germination ecology in the endangered Carrington Falls Grevillea (Grevillea rivularis, Proteaceae)
The aims of this study were to examine the density and vertical distribution of the soil-stored seed bank and to investigate the role of heat and scarification as cues for germination of fresh and soil-Stored seed.
Fire-related germination cues for soil-stored seedbanks of fire-prone habitats in the Sydney region, Australia
Approximately 89% of species in fire-prone vegetation types of the Sydney region are assumed to have a soil seedbank. While a post-fire gennination pulse is common for such species, the mechanisms
Seed germination ecology in southwestern Western Australia
Application of research on seed germination has already enhanced the establishment of seedlings in the restoration of mine sites and is becoming important in aspects of the breeding and selection of native plants for the cut flower, bedding plant and essential oil industries.
Role of Fire in Seed Germination of Woody Taxa in California Chaparral
Germination behavior of 45 tree, shrub, subshrub, and liana taxa from fire- prone coastal sage scrub and chaparral was investigated, finding that most coastal sage subshrubs germinate readily in the absence of fire-related stimuli and thus are capable of colonizing other forms of disturbance.
Seedling Recruitment Strategies in Obligate-Seeding and Resprouting Banksia Shrubs.
Results suggest that selection has acted on B. ericifolia to minimize the chance of zero seedling survival by distributing the risks over more than one germination episode, and there was no consistent evidence to support the hypothesis that selection on this species has increased its probability of Seedling survival during anyone germination opportunity.
The Role of Fire in Establishment of Seedlings of Serotinous Species From the Sydney Region
It was concluded that predation of newly germinated seedlings may be the most important restriction on seedling establishment in unburnt populations.
Population dynamics of the shrub Acacia suaveolens (Sm.) Willd.: Fire and the transition to seedlings
Field observations of emergent seedlings confirm that post-fire emergence is concentrated over a small range of soil depths directly related to the intensity and duration of heating that occurs, whilst occasional seedlings may appear from greater or lesser depths largely dependent upon the spatial heterogeneity of soil heating in natural fires.
