“…Unlike ivy, I. aquifolium starts to produce fruits at the age of 5 (Table 1, Valladares et al 2005). Once established and fruiting, directed seed dispersal between holly patches (Møller et al 2012) and holly's ability to produce vegetative ramets and germinate also in shady conditions (Valladares et al 2005;Stokes et al 2014) result locally in large populations. As a consequence, holly cover at the plot level may amount to high values (Table 3).…”

Drivers of broadleaved evergreen species spread into deciduous forests in the southern Swiss Alps

The spread of non-native species into natural communities is a noticeable phenomenon linked to global change. Drivers of such invasions, however, may differ according to specific regional environments. Here, we aim at disentangling the role of selected climate and non-climate drivers on the spread of native (Hedera helix and Ilex aquifolium) and nonnative (Prunus laurocerasus and Trachycarpus fortunei) evergreen species in mature deciduous forests in southern Switzerland. Covers of target evergreens were determined using 200 quadratic plots of 100 m 2 , distributed on a regular grid of 100 × 100 m and spanning a steep climatic gradient ranging from −0.4 to 3.0 °C in the average temperature of the coldest month. Species covers were used as response variables to be related to climate, stand structure, disturbances, propagule pressure and geomorphology proxies by performing tobit regressions. Propagule pressure resulted to be the main driver of occurrence for three considered species, while mesoclimate and stand structure played only a secondary role. In contrast, the presence of native I. aquifolium was mostly correlated with the temperature of the coldest month, though with an overall low impact on cover. Our study demonstrates different drivers of invasion for native and non-native species with similar life history traits. In particular, differences emerge from ecological requirements (niche) and propagule pressure. The ongoing spread of evergreen broadleaved species at the regional scale demonstrates how evergreens invade a largely empty ecological niche, mainly issued by land-use change rather than climate warming.

In cities, naturally regenerating plant populations are critical in sustaining both ecological function and ecosystem services. However, scientists have a limited understanding of the urban ecosystem conditions and stressors that influence basic life‐history processes and constraints for plant populations. Here, we synthesize current research on the recruitment dynamics of urban plants (processes associated with adding individuals to populations) and present a conceptual framework for urban recruitment limitation. From grasslands to forests, and from natural to constructed habitats, multiple urban drivers – including climate, land‐cover change, pollution, and biotic invasions – affect plant recruitment. These drivers often interact, and their effects are frequently species‐, habitat‐, or region‐specific. Furthering a “mechanistic” understanding (one that focuses on the underlying ecological mechanisms of observed phenomena) of how these drivers alter plant population dynamics will improve the conservation, management, and restoration of urban greenspaces.

“…The relationship between native birds, especially frugivorous species, and introduced plants is complex. Not only do many invasive trees and shrubs expand habitat choices for native birds, but these birds contribute to invasive plant spread through fruit consumption and seed dispersal (Reichard et al 2001;Caughlin et al 2012;Moller et al 2012).…”

Nonnative, Noninvasive Woody Species Can Enhance Urban Landscape Biodiversity

Increasingly, homeowner associations and municipalities are requiring a certain percentage of native trees and shrubs as part of any new landscape installation. These native species mandates make numerous claims as to the superiority of native plants over introduced species, including their ability to enhance ecosystem biodiversity. In contrast, nonnative trees and shrubs are labeled as harmful to biodiversity, primarily because they are improperly grouped with known invasive species. This review summarizes the current published science regarding the effects of native and nonnative woody species on urban landscape stability as measured by biodiversity of associated plants, birds, insects, reptiles, and mammals. The preponderance of studies demonstrate that parameters other than species nativity have the greatest influence on biodiversity of these groups. Rather than limiting tree and shrub selection lists to a narrow palette of native species, a more practical, science-based approach to enhancing urban landscape biodiversity is suggested.
