In 2010, the international community, under the auspices of the Convention on Biological Diversity, agreed on 20 biodiversity-related “Aichi Targets” to be achieved within a decade. We provide a comprehensive mid-term assessment of progress toward these global targets using 55 indicator data sets. We projected indicator trends to 2020 using an adap...

Substantial progress has been made in understanding how pathways underlie and mediate biological invasions. However, key features of their role in invasions remain poorly understood, available knowledge is widely scattered, and major frontiers in research and management are insufficiently characterized. We review the state of the art, highlight rec...

Reducing rates of biodiversity loss and achieving environmental goals requires an understanding of what is threatening biodiversity, where and how fast the threats are changing in type and intensity, and appropriate actions needed to avert them. One might expect that the Information Age – typified by a deluge of data resulting from massive and wide...

Although research on human-mediated exchanges of species has substantially intensified during the last centuries, we know surprisingly little about temporal dynamics of alien species accumulations across regions and taxa. Using a novel database of 45,813 first records of 16,926 established alien species, we show that the annual rate of first record...

Harmonised, representative data on the state of biological invasions remain inadequate at country and global scales, particularly for taxa that affect biodiversity and ecosystems. Information is not readily available in a form suitable for policy and reporting. The Global Register of Introduced and Invasive Species (GRIIS) provides the first countr...

The Country Compendium of the Global Register of Introduced and Invasive Species (GRIIS) is a collation of data across 196 individual country checklists of alien species, along with a designation of those species with evidence of impact at a country level. The Compendium provides a baseline for monitoring the distribution and invasion status of all...

Alien species are introduced to new regions in many different ways and for different purposes. A number of frameworks have been developed to group such pathways of introduction into discrete categories in order to improve our understanding of biological invasions, provide information for interventions that aim to prevent introductions, enable repor...

The year 2020 and the next few years are critical for the development of the global biodiversity policy agenda until the mid-21 st century, with countries agreeing to a Post-2020 Global Biodiversity Framework under the Convention on Biological Diversity (CBD). Reducing the substantial and still rising impacts of invasive alien species (IAS) on biod...

Biodiversity data are being collected at unprecedented rates. Such data often have significant value for purposes beyond the initial reason for which they were collected, particularly when they are combined and collated with other data sources. In the field of invasion ecology, however, integrating data represents a major challenge due to the notor...

Biological invasions are a defining feature of the Anthropocene, but the factors that determine the spatially uneven distribution of alien plant species are still poorly understood. Here, we present the first global analysis of the effects of biogeographic factors, the physical environment and socio-economy on the richness of naturalized and invasi...

The Global Register of Introduced and Invasive Species (GRIIS) presents validated and verified checklists (inventories) of introduced (alien) and invasive alien species at the country, territory, and associated island level.

The annotated checklist of 228 (217 accepted and 11 synonyms) introduced (alien) and invasive alien species known to occur in Uzbekistan.

The Global Register of Introduced and Invasive Species (GRIIS) presents annotated country checklists of introduced and invasive species. Annotations include higher taxonomy of the species, synonyms, environment/system in which the species occurs, and its biological status in that country. Invasiveness is classified by evidenced impact in that count...

Significance Our ability to predict the identity of future invasive alien species is largely based upon knowledge of prior invasion history. Emerging alien species—those never before encountered as aliens—therefore pose a significant challenge to biosecurity interventions worldwide. Using a global database of the first regional records of alien spe...

This annotated checklist is focused on introduced (alien) and invasive species that are known to occur in South Africa. The International Union for Conservation of Nature, (IUCN) describes an Introduced/ Alien and Invasive alien species as follows: An Introduced/ Alien species means a species, subspecies, or lower taxon occurring outside of its nat...

Invasive species are a global problem for conservation, economics and health. Information on their distribution, spread and impact are essential to inform national and international policy on biodiversity. Furthermore, demand for these data are only likely to increase as recent environmental change results in the widespread reconfiguring of species...

Using the recently built Global Naturalized Alien Flora (GloNAF) database, containing data on the distribution of naturalized alien plants in 482 mainland and 362 island regions of the world, we describe patterns in diversity and geographic distribution of naturalized and invasive plant species, taxonomic, phylogenetic and life-history structure of...

Invasive alien species (IASs) on islands have broad impacts across biodiversity, agriculture, economy, health and culture, which tend to be stronger than on continents. Across small-island developing states (SIDSs), although only a small number of IASs are widely distributed, many more, including those with greatest impact, are found on only a smal...

This paper provides a categorised selection of scientific articles published in 2015, that discuss the occurrence of alien and invasive alien species (IAS) in wetlands of significance, the impacts of these species on wetland biodiversity and the management of this threat. The articles are separated into three categories a) articles that discuss imp...

Preventing the arrival of invasive alien species ( IAS ) is a major priority in managing biological invasions. However, information on introduction pathways is currently scattered across many data bases that often use different categorisations to describe similar pathways. This hampers the identification and prioritisation of pathways to meet the m...

In a world where invasive alien species (IAS) are recognised as one of the major threats to biodiversity, leading scientists from five continents have come together to propose the concept of developing an international association for open knowledge and open data on IAS—termed " INVASIVESNET ". This new association will facilitate greater understan...

The Invasive Species Specialist Group (ISSG) is a global network of scientific and policy experts on invasive species, organized under the auspices of the Species Survival Commission (SSC) of the International Union for Conservation of Nature (IUCN). ISSG aims to reduce threats to natural ecosystems and the native species they contain by increasing...

Farmers have been fighting weeds and pests since the beginnings of agriculture, but the impacts of invasive alien species (IAS) on native species, habitats and ecosystem services have only been brought to the world’s attention relatively recently. Invasive plants, also known as environmental weeds, constitute an insidious ‘biological pollution’. Un...
