Planted forests of non-native conifers make up around 36% of Britain's total wooded area. Increasing the area of native woodlands - including converting non-native conifer to native woodland where appropriate - is an aim of the UK Forestry Standard Guidelines on Biodiversity. It is unclear how much ...

All around the globe, humans have greatly altered the abiotic and biotic environment with ever-increasing speed. One defining feature of the Anthropocene epoch^{1, 2} is the erosion of biogeographical barriers by human-mediated dispersal of species into new regions, where they can naturalize and cause ...

The Southern African Plant Invaders Atlas (SAPIA) is a mapping project, launched in 1994, to collate data on the distribution, abundance and habitat types of invasive alien plants in southern Africa. The SAPIA database is a computerized catalogue of some 70 000 locality records of more than 600...

The objective of this work was to compare and contrast the patterns of alien plant invasions in the world's five mediterranean-climate regions (MCRs). We expected landscape age and disturbance history to have bearing on levels of invasion. We assembled a database on naturalized alien plant taxa...

This paper presents an assessment of a large, national-scale alien plant control program that has operated in South Africa for 15 years. We reviewed data from three national-level estimates of the extent of invasion, records of the costs and spatial extent of invasive species control operations,...

The absence of natural enemies being keystone to the success of invasive alien plants (IAPs) can only be accepted once all the factors governing the invader and the ecosystems it invades have been established. Few studies have attempted this approach. This study reports on the relations between the ...

Pompom weed, Campuloclinium macrocephalum (Less.) DC. (Asteraceae), is a South American invasive plant that was first recorded in South Africa in the early 1960s. In the 1980s, C. macrocephalum started slowly extending its range and in the 1990s and 2000s it entered a dramatic expansion phase. It...

A prime aim of invasion biology is to predict which species will become invasive, but retrospective analyses have so far failed to develop robust generalizations. This is because many biological, environmental, and anthropogenic factors interact to determine the distribution of invasive species....

The primary objective of this publication is to provide an overview of the species identity, invasion status, geographical extent, and abundance of alien plants in South Africa, Swaziland and Lesotho, based on field records from 1979 to the end of 2000. The dataset is all the species records for...
