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...

Hypericum androsaemum L. (tutsan) invades pastures and natural ecosystems in high rainfall areas of south-eastern Australia. The rust fungus Melampsora hypericorum was detected in Australia in 1991 and drastically reduced the extent of H. androsaemum populations in some areas. The impact of the...

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...

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...

Falcataria moluccana (Miq.) Barneby and Grimes is a large tree that has become invasive in forests and developed landscapes across many Pacific islands. A fast-growing nitrogen fixing species, it transforms invaded ecosystems by dramatically increasing nutrient inputs, suppressing native species...

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...

This is the overview of the status of native and protected breeds of animals in the Republic of Croatia, with reference to those contained in the Nature Park Lonjsko Polje (PPLP), to determine the risk level of the total population of native breeds of domestic animals. Traditionally, management of...
