“…In the case of E. australis, dormancy break occurs during a wet cold period, which probably means that in the field some seeds (26%-64%) may germinate after the first rains, which occur mainly in autumn or early winter. Many typical species in Mediterranean-type ecosystems form a persistent soil seed bank which enables them to survive in a risk environment for long periods of the year (Putwain & Gillham 1990). This is the case of E. australis, which forms a seed bank with a large number of seeds that remain in the soil for a certain period of the year.…”

We studied the germination of Erica australis seeds and their responses to different treatments (high temperature, acidic condition, cold stratification, gibberellic acid applications). Germination was very low in untreated seeds (3%) and required approximately one month to start, but increased in all the treatments tested, reaching a value of 100% when seeds were treated with gibberellic acid (25 ppm). Exposure to heat and to low pH promotes germination and reduces time to germinate, which indicates that germination is related to passage of fire and to soil pH. Germination of this species is also correlated with wet and cold conditions and dormancy can be classified as being of the physiological type.

“…A técnica mais utilizada na determinação do número de sementes é a estimativa da emergência de plântulas diretamente a partir da amostra de solo, que, por sua vez, deve ser espalhado em fina camada sobre recipientes acondicionados em casa de vegetação, a fim de assegurar as condições ambientais favoráveis ao surgimento de plântulas (Putwain & Gillham, 1990). No entanto, esse método de germinação geralmente subestima o banco de sementes, porque as sementes das plantas daninhas apresentam diferentes fluxos de emergência, podendo germinar ou não durante a avaliação (Gross, 1990).…”

“…Because seed density declines with depth in the soil profile salvaging to greater depth can dilute the seed bank while salvaging at shallower depths could waste some of the propagule pool (Putwain and Gillham 1990;Tacey and Glossop 1980;Macdonald et al 2015). Placement depth, in turn, will influence emergence in a species-specific way (Bowen et al 2005;Holmes 2001;Tacey and Glossop 1980;Zhang et al 2001).…”

Forest restoration following surface mining disturbance: challenges and solutions

Many forested landscapes around the world are severely altered during mining for their rich mineral and energy reserves. Herein we provide an overview of the challenges inherent in efforts to restore mined landscapes to functioning forest ecosystems and present a synthesis of recent progress using examples from North America, Europe and Australia. We end with recommendations for further elaboration of the Forestry Reclamation Approach emphasizing: (1) Landform reconstruction modelled on natural systems and creation of topographic heterogeneity at a variety of scales; (2) Use and placement of overburden, capping materials and organic amendments to facilitate soil development processes and create a suitable rooting medium for trees; (3) Alignment of landform, topography, overburden, soil and tree species to create a diversity of target ecosystem types; (4) Combining optimization of stock type and planting techniques with early planting of a diversity of tree species; (5) Encouraging natural regeneration as much as possible; (6) Utilizing direct placement of forest floor material combined with seeding of native species to rapidly re-establish native forest understory vegetation; (7) Selective ongoing management to encourage development along the desired successional trajectory.
