Struggling to maintain native plant diversity in a peri-urban reserve surrounded by a highly anthropogenic matrix

  journal={Biodiversity and Conservation},
High human density and land use intensity often coincide with biodiversity hotspots making peri-urban reserves a keystone for conserving natural remnants in a highly anthropogenic matrix. Particularly, intense propagule pressure by alien plant species can pose a threat to native biodiversity. However, little is known about the factors that determine invasibility and the role of roads and other human disturbances for such small protected areas. Within a peri-urban reserve close to the city of… Expand

Invasive alien plant species, fragmentation and scale effects on urban forest community composition in Durban, South Africa
BackgroundUrban forests are under increased pressure from invasion by exotic (alien) species. The vegetation present in the matrix of urban sites is a rich source of alien invasive propagules, whichExpand
Settlements as a source for the spread of non-native plants into Central European suburban forests
Urbanization is considered as a major driver for biotic homogenization. Urbanization also promotes the dispersal of non-native species. This study examined the roles of suburban settlements and ofExpand
Consequences of land-use change and the wildfire disaster of 2017 for the central Chilean biodiversity hotspot
Central Chile is an important biodiversity hotspot in Latin America. Biodiversity hotspots are characterised by a high number of endemic species cooccurring with a high level of anthropogenicExpand
Comparing invasive alien plant community composition between urban, peri-urban and rural areas; the city of Cape Town as a case study
Abstract Urban areas are considered hotspots for invasions by alien plant communities. Anthropogenic activity within these areas often facilitates the introduction and spread of invasive alienExpand
Native Plant Diversity and Composition Across a Pinus radiata D.Don Plantation Landscape in South-Central Chile—The Impact of Plantation Age, Logging Roads and Alien Species
Investigation of plant species diversity and composition in a Pinus radiata landscape in south-central Chile, a biodiversity hotspot, by sampling understory vegetation in different plantation age classes, along forest roads and in natural forest remnants in order to find effective conservation measures for native biodiversity.

Non-native Pines Are Homogenizing the Ecosystems of South America
A large area previously dominated by native ecosystems in South America is now covered by monocultures of non-native tree species, mainly of the genus Pinus. Currently, pine plantations and theExpand
Assessing the impact of revegetation and weed control on urban sensitive bird species
This study uses a case study to explore how urban restoration activities impact different bird species and recommends that weed control be implemented in concert with replanting of native vegetation to provide the understory structure preferred by urban sensitive birds. Expand
Invasion of the alien shrub Prunus laurocerasus in suburban deciduous forests: Effects on native vegetation and soil properties
The removal of young P. laurocerasus individuals would be an appropriate management practice for this invasive shrub species in suburban deciduous forests in the region of Basel, Switzerland. Expand
Distribution patterns of ruderal plant diversity in Greece
Ruderal plant species typically occur and prevail in frequently disturbed areas especially in sites with pronounced direct or indirect human activity. In Greece ruderal taxa (both exclusive andExpand
Edaphic beetle (Insecta: Coleoptera) diversity over a forest-matrix gradient in a tropical rainforest
The results suggest that the sugarcane matrices, chiefly the matrix after 2 months of replantation, sustain an impoverished beetle assemblage when compared with the forest fragment, highlighting the importance of forest fragments embedded in harsh matrices for the maintenance of biodiversity.

Alien plants in urban nature reserves : from red-list species to future invaders?
Urban reserves, like other protected areas, aim to preserve species richness but conservation efforts in these protected areas are complicated by high proportions of alien species. We examined whichExpand
Distance to suburban/wildland border interacts with habitat type for structuring exotic plant communities in a natural area surrounding a metropolitan area in central Chile
Background: The explosive growth of urbanisation in Mediterranean ecosystems in Chile has favoured the rapid expansion of exotic plant species, yet factors driving these invasion patterns in adjacentExpand
Influence of Elevation, Land Use, and Landscape Context on Patterns of Alien Plant Invasions along Roadsides in Protected Areas of South-Central Chile
Alien plant species are a growing concern in protected areas, yet little information is available on the role of roads as corridors for alien species and the effects of elevation, land use, andExpand
Ecological and biological determination of invasion success of non-native plant species in urban woodlands with special regard to short-lived monocarps
A literature analysis aiming at identifying possible biological and ecological determinants of monocarpic plants’ invasive success in urban woodlands indicates that this ability may be due to such traits as high fecundity rates, effective dispersal mechanisms, early germination, high rate of growth and the overall big size of plants, presence of autonomous pollination and high shade-tolerance.

Although conservation attitudes may be challenged by the novelty of some urban ecosystems, it is promising to consider their associated ecosystem services, social benefits, and possible contribution to biodiversity conservation. Expand
Human population density explains alien species richness in protected areas
Human population density has emerged here as an important predictor of alien species richness in protected areas across taxa, providing a basis for guidelines on where to focus surveillance and eradication efforts. Expand
Non-native plant invasions of United States National Parks
This work investigated relationships among non-native plant species richness, the number of threatened and endangered plant species, nativespecies richness, latitude, elevation, park area and park corridors and vectors, and revealed patterns that can be further explored empirically to understand the underlying mechanisms.

Limited native plant regeneration in novel, exotic-dominated forests on Hawai’i
It is suggested that a wide diversity of growth strategies among the exotic species on Hawai’i may limit the opportunities for native plants to colonize exotic-dominated forests. Expand
Do urban areas act as foci for the spread of alien plant species? An assessment of temporal trends in the UK
There has been a reduction in the urban association of Archaeophytes that is likely to have resulted from the recovery of archaeophytes associated with non-urban habitats, following their decline in mid-20th century, rather than from the movement of aliens into the wider countryside from urban habitats.

The distribution and habitat associations of non-native plant species in urban riparian habitats
Questions: 1. What are the distribution and habitat associations of non-native (neophyte) species in riparian zones? 2. Are there significant differences, in terms of plant species diversity,Expand
