The rampant spread of the invasive alien plant Parthenium hysterophorus (Asteraceae) in subtropical South Africa prompted research into biological control methods more than a decade ago. Parthenium impacts broadly on agriculture, biodiversity conservation and health. Elsewhere, significant control...

This proceedings contains papers focusing on the current situation of invasive alien species (IAS; including insect pests, weeds and aquatic organisms) in natural and agricultural areas in the region. These papers discusses the different aspects of IAS, presenting the latest situation that has been ...

This proceedings contains papers discussing new research results and innovative methods in the area of weed science. Topics covered include: (i) weed biology, ecology, monitoring, population dynamics, and biodiversity/ecological functions; (ii) modelling and molecular methods in weed science; (iii) ...

Mikania micrantha (Asteraceae) commonly known as mikania, is a major invasive alien plant (IAP) in the tropical humid agricultural and forest zones of the Asia-Pacific region. This fast-growing Neotropical vine is able to smother plants in agricultural ecosystems, agroforestry and natural habitats, ...

In September 2013, the European Commission published a proposal for a Regulation on the prevention and management of the introduction and spread of invasive alien species. The proposal aims to address the threat of invasive alien species comprehensively, minimising and mitigating their impacts on...

Invasive species are mostly nonnative species introduced accidentally or intentionally by humans in natural or established habitat where they threat the environment, economy and/or health. Several thousands of the alien species have become established in different parts of the world over the past...

This paper reviews the impacts of weeds that threaten either pasture production or native grassland biodiversity values. It then reviews weed management strategies in grasslands to control weeds. We describe differing perceptions of grassland weeds and the associated societal values underlying...

Chromolaena odorata (L.) King and Robinson (Asteraceae), a shrub native to tropical America, was first introduced into West Africa (Nigeria) in 1937, and later became invasive. The weed has since spread to other countries in the West African subregion, threatening agriculture, biodiversity and...

Chromolaena odorata (L.) King & Robinson (Asteraceae), an invasive alien plant of terrestrial habitat in many tropical and sub-tropical regions of the world, was investigated in the South-West Ecological Zone of Nigeria. Investigations, including field observations on C. odorata and a survey of...
