Urban domestic gardens (VII): a preliminary survey of soil seed banks

Abstract

2005). Urban domestic gardens (VII): a preliminary survey of soil seed banks. AbstractAs part of a larger survey of biodiversity in private gardens in Sheffield, UK, we examined the composition and diversity of the soil seed banks in each of 56 gardens. Six soil cores from each garden revealed 2759 seedlings of 119 taxa, although the real species richness is likely to be much higher than this. By far the most abundant species were weedy natives, while the most common alien was Buddleja davidii. Seeds of perennial herbs were more abundant than hundreds of all other life forms combined. More frequent species were also more abundant, but the relationship was weak. Numbers of species in the seed bank and in the garden flora were positively but very weakly related. Seeds were quite evenly distributed between 0 -5 cm and 5 -10 cm soil layers, and most seeds were of species known to have persistent seed banks. Seeds of some species were largely confined to gardens in which the plant was growing, but others were not.

Um jardim florido? A vegetação cultivada em quintais urbanos através de um gradiente social

Los estudios de la flora urbana en general se concentran en fragmentos de bosques (HOPE et al, 2003) aunque las especies cultivadas sean las dominantes en los ecosistemas urbanos, y de ellas poco se sepa.…”

The Grass Is Always Greener on the Other Side of the Fence: The Flora in Urban Backyards of Different Social Classes

“…However, household backyards provide an extensive and undervalued resource to increase urban biological diversity, as well as its ecosystem services (MAURER et al, 2000;GODDARD et al, 2010). The importance of private backyards to biodiversity conservation (including the preservation of endangered plant and animal species) has been increasingly acknowledged; however, there has been virtually no attempt to describe the biological diversity composition and distribution in these spaces (GASTON et al, 2005;THOMPSON et al, 2005;SMITH et al, 2006a;LORAM et al, 2007;MARCO et al, 2008;DAVIES et al, 2009;GODDARD et al, 2010;GALLUZZI et al, 2010;BEUMER and MARTENS, 2014).…”

El Césped del Vecino es más Verde: Flora de Patios a Través de un Gradiente Social

“…Hay un amplio reconocimiento de la importancia de los patios privados a la conservación de la biodiversidad (incluyéndose a preservación de especies amenazadas vegetales y animales), pero prácticamente no ha habido intentos de describir la composición y distribución de la diversidad biológica presente en los patios (GASTON, et al, 2005;THOMPSON, et al, 2005;SMITH, et al, 2006a;LORAM, et al, 2007;ANGEOLETTO, 2008;LORAM, et al, 2008;MARCO, et al, 2008;DAVIES, et al, 2009;GODDARD, et al, 2010;SIVIERO, et al, 2011). Los estudios de la flora urbana en general se concentran en fragmentos de bosques (HOPE, et al, 2003) aunque las especies cultivadas sean las dominantes en los ecosistemas urbanos, y de ellas poco se sepa (MARCO, et al, 2008).…”
