“…Stiles (1982) examined Christmas Bird Count data and the increasing popularity of multiflora rose (Rosa multiflora) as a multi-use ornamental in suburban and urban areas. He concluded that there was a causal link between increased planting of R. multiflora and the increased range of Northern Mockingbirds (Mimus polyglottos) in the northeastern U.S. (Stiles 1982).There is also evidence that longer temporal availability of non-native fruits has encouraged migratory birds to postpone migration (Debussche and Isenmann 1990).…”

“…A number of authors have noted birds in the suburban environment responding to the habitats, fruits, and flowers of specific plantings of non-native ornamentals. Obviously, such plants represent a food source to native and non-native birds when other food is scarce or unavailable (Siegfried 1968, Debussche et al 1982, Debussche and Isenmann 1990, White and Stiles 1992.Plants in urban environments occur as patches of ornamental landscapes, urban forests, and greenbelts. Those plants occupying edge areas and gaps produce more fruit than species growing under a closed canopy, even among shade tolerant individuals.…”

Abstract:Humans have introduced many non-native plants into urbanizing landscapes. In numerous cases, the dispersal and establishment of non-native plants are facilitated by birds. We have reviewed documented relationships between birds and non-native plants with specific attention to the urbanizing environment. Birds consume fruits and disperse seeds of non-native plants.They may also increase seed production or plant/seed survival by pollinating non-native plant species or consuming insect predators, respectively. Some avian frugivores facilitate the spread of, and benefit from, non-native plant species. In contrast, some avian nectarivores and insectivores have evolved mutual isms with specific plants and have been negatively influenced by the spread of competing, non-native plants. We enumerate the characteristics of successful, avian-dispersed fruit displays, and then highlight conditions in the urbanizing landscape that influence avian community structure and the spread of non-native plants. Finally, we discuss how these characteristics should influence management decisions and future research directions. INTRODUCTIONHorticultural introductions bring plants across physical barriers to areas of potentially suitable habitat. Having thus overcome geographical barriers to invasion, horticultural plants need only an effective means of dispersal to become naturalized and possibly invasive (Kruger et at. 1986). Birds play an important role in the dispersal of many non-native horticultural plant species from human-altered environments (White and Stiles 1992). 180Chapter 9 movement of diaspores over large distances, and by a high probability that diaspores will be deposited in microenvironments suitable for germination and survival (Proctor 1968, Howe andSmallwood 1982).Some birds enhance non-native plant dispersion and may, in turn, be affected by the resulting plant community depending on their feeding guild and habitat use. Frugivores and omnivores may benefit widely from and, in some cases, facilitate the spread of non-native plant species.Frugivorous and omnivorous birds are often generalists who prove quite able to incorporate new fruit types into their diet (MacDonald 1986). Relationships between granivorous or nectarivorous birds and plants often evolve more closely; thus, non-native plants that rely on avian dispersal of seeds or pollen appear to be less likely to find suitable dispersers in non-native habitat (Stiles 1989). Similarly, non-native plants that displace native vegetation are more likely to negatively affect granivores and nectarivores than frugivorous birds (Breytenbach 1986). There have been notable exceptions, however, in which non-native horticultural plants with showy flowers have been utilized by nectarivorous birds (Waterhouse 1997).Insectivorous birds also can influence the spread of non-native plants through predation on herbivorous insects, but because their effect is mediated by other organisms, the influences of insectivorous birds on plants is usually not as ecologically salient a...

“…The establishment stage involves mainly local dispersal, whereas the spread stage involves rapid expansion that is mostly dominated by LDD (Kot et al 1996 ;Clark 1998 ). In these two post -entry stages, humans play an increasingly important role (see, for example, Von der Lippe & Kowarik 2007 ), yet natural vectors are probably still the key dispersers (Debussche & Isenmann 1990 ;Richardson et al 2000a ;Murphy et al 2008 ;Westcott et al 2008 ). Dispersal at the post -entry stage is crucially important to the extent that successful dispersal away from the initial point of introduction marks the transition from ' alien ' through ' naturalized ' to ' invasive ' ( sensu Richardson et al 2000b ).…”

“…P. coccinea produces fruits profusely and is widely used in gardens and hedges in this region (Debussche and Isenmann 1990;Malric 2004), which makes it a widely available resource for frugivorous birds. In fact, P. coccinea is the most frequent food item in the gizzard contents of the main bird dispersers in the Montpellier region (Debussche andIsenmann 1990, 1994), which suggests that opportunities for seed dispersal are great.…”

We evaluate the mechanisms that determine the establishment of the non-indigenous shrub Pyracantha coccinea (Rosaceae) in the Montpellier region of southern France. P. coccinea establishes in abandoned agricultural fields in this region; yet, despite its high propagule pressure, it has not become a widespread invasive. We hypothesized that the disturbance conditions prevailing in abandoned agricultural fields right after abandonment may enhance the emergence, survival and growth of P. coccinea, but that shortly after abandonment colonizing vegetation prevents further establishment of this species.We conducted a field experiment to evaluate this hypothesis, studying the response of seedling emergence and growth of P. coccinea to soil and vegetation disturbance. Our results show that both lack of vegetation cover and soil disturbance promote the emergence of seedlings of P. coccinea. Thus, the disturbance conditions prevailing in abandoned agricultural fields seem crucial to allow establishment of this species. However, other factors such as lack of summer dormancy and seed predation might explain why this species has not become a widespread invasive.
