“…This observation has been made from other habitats (e.g. Partridge 1989; although see Pierce & Cowling 1991a). This suggests that for the coastal dune system studied here, similar factors operate to delineate aboveground communities and seed banks at landscape and local scales, but the details are different at the smaller scale (Matlack & Good 1990).…”

. The germinable soil seed bank is described from a coastal barrier island off the northwest coast of Florida, USA. Soil samples collected from seven vegetation types, recently deposited dredge spoil and unvegetated areas in autumn 1990 and spring 1991 were placed out in greenhouse trays. 110 taxa germinated from the samples with the largest number (41) being C3 perennial dicots. The largest number of taxa germinated from dry (57) and wet (54) swales, the fewest (one species: Heterotheca subaxillaris) from strand. Similarity of seed bank densities to above‐ground species cover was low (Jaccard's Index = 0.36), not different between vegetation types, but higher in the autumn than in the following spring. Compositional gradients in the seed bank and above‐ground vegetation determined using DCA ordination were highly correlated and related to distance from mean high water, and plot elevation. At the landscape scale, the seed bank provided an equally clear delineation of vegetation types to that based upon the above‐ground vegetation. The seed bank of low disturbance, late‐succession vegetation types (wooded dunes, swales, marshes) was well developed (high species richness, emergent density, and percentage annual species) with the exception that the large‐seeded woody species (i.e. Quercus spp.) were absent from the wooded dune seed bank. By contrast, a poorly developed and transient seed bank occurred in more frequently disturbed (extensive sand movement, salt spray), early successional dredge spoil, unvegetated areas and strand. These contrasts support a general pattern of increasing seed bank development and a persistent rather than transient seed bank with decreasing disturbance frequency, increasing time since disturbance and successional maturity.

“…However, the nature of this relationship is equivocal (Donelan & Thompson 1980;Pierce & Cowling 1991a), mainly because few studies compare the seed bank of a diversity of habitats (although see Thompson & Grime 1979;Partridge 1989). Most seed bank studies consider a single habitat or plant community, e.g., grassland, forest, wetland (e.g.…”

“…ericoides forest. It was largely confined to bare sites with exposed subsoil, indicating germination of freshly-deposited seed rather than from a soil seed bank, in a manner similar to K. ericoides germination under Pteridium esculentum femland and forest on Banks Peninsula (Partridge 1989). In the present study, most seedlings of K.…”

The establishment, growth, and successional characteristics of Kunzea ericoides in stands 2-70 years old were studied near Dunedin, New Zealand. K. ericoides seedlings established readily on bare ground (mean density 3.2 m -2 after two years), but at a lower rate in grazed pasture (mean density 1.3 m -2 after at least 12 years). K. ericoides grew in dense stands (about I m -2 at 27-50 years) that suppressexl growth of other tree species until substantial reduction of K. ericoides stem density after about 50 years. Species diversity of forest shrubs, ferns and herbs increased little with age of K. ericoides stand. By 70 years podocarps were represented only by scattered seedlings, and succession through K. ericoides to mature podocm-pbroadleaved forest had barely begun. Implications of the results for alternative models of succession are discussed, as are the implications of K. ericoides ecology for firewood crop management.

“…Aristotelia serrata and Fuchsia excorticata have seeds persistent in the soil (Moles et al 2000, table 1), and Sophora has tough-coated seed and forms long-lived seed banks (Partridge 1989), confirming their seral habitat preference.…”

Winter leaf loss in the New Zealand woody flora

Approximately 27 species (c. 5%) of the New Zealand woody flora have a marked loss of leaves in winter, although only 10 species are consistently fully deciduous and no extensive vegetation type is dominated by them. There are no summer deciduous species. The deciduous habit appears in most cases to have evolved independently within New Zealand from either ancestors or immigrants with short leaf life spans. New Zealand deciduous or semideciduous species typically lose substantial numbers of leaves throughout the growing season, and leaf loss is often gradual throughout winter but accelerated by frost. The deciduous habit in New Zealand tends to be a leaf-or shoot-level feature reflecting short leaf life spans and winter stress on individual shoots, rather than a systematic feature of the canopy-level organisation of the plant. Degree of deciduousness varies with taxon, plant age, climate, and soil fertility. A physiological study of cooccurring fully deciduous (Fuchsia excorticata) and semideciduous (Aristotelia serrata) trees in the South Island established that higher growing-season productivity of Fuchsia compensated for carbon gain forgone over winter. However, Fuchsia was significantly favoured over Aristotelia only on the coldest sites. Aside from some inland basins of the South Island, New Zealand has milder winters than those that favour deciduous taxa globally, and this is the primary reason for the low incidence of deciduous species. Even so, a number of deciduous species are common throughout. New Zealand deciduous trees and shrubs are typically fast growing and are characteristic of seral or forest marginal habitat on nutrient-rich soils developed in recent alluvium or debris. The relatively low nutrient status of most New Zealand forest soils makes a deciduous phenology, with its necessarily high turnover of nutrients, less competitive than a nutrient-conserving evergreen phenology. Deciduous species are often also divaricating, or have close relatives that are, and share a preference for nutrient-rich soils with this growth form. This strong relationship between the two habits suggests both are, in part, adaptations to stressful climates by plants with high-productivity leaves.
