Abstract The evidence base for the benefits of urban nature people and biodiversity is strong. However, cities are diverse social environmental contexts likely to influence observed effects nature, application differing contexts. To explore biases in we text-matched city names abstracts affiliations 14 786 journal articles, from separate searches articles on biodiversity, health wellbeing impacts ecosystem services. City were found 51% article 92% affiliations. Most large studied many times...
Abstract The rate of transportation, introduction, dissemination, and spread nonnative species is increasing despite growing global awareness the extent impact biological invasions. Effective policies are needed to prevent an increase in significant negative environmental economic impacts caused by invasive species. Here we explore this issue context history invasion subsequent regulation cacti introduced South Africa. We consider seven approaches restricting trade banning following: (1)...
Background: South Africa has a long history of managing biological invasions. The rapid increase in the scale and complexity problems associated with invasions calls for new, more strategic management approaches. This paper explores approaches cactus Africa. Cacti (Cactaceae) have had socio-economic benefits, considerable negative environmental impacts, wide range interventions Objectives: To guide future invasions, national framework was developed by African Cactus Working Group....
Invasive alien species require co-ordinated strategic management if negative impacts are to be effectively avoided. Here we describe a strategy for the of Parthenium hysterophorus L. (Asteraceae) in South Africa. P. is an annual herb native tropical America, which has become invasive over 30 countries. The sets goals (1) prevention spread new areas; (2) local eradication isolated populations; (3) containment areas where not possible; and (4) actions protect assets no longer option. We...
This study is the first detailed assessment of an invasion by Acacia implexa (Benth.) (screw-pod wattle) anywhere in world. Approximately 30 000 A. individuals were found spread over about 600 ha (a condensed canopy area ~ 96 ha) three geographically distinct populations, all Western Cape, South Africa. Population structures indicate rapidly increasing populations at sites, with vegetative suckering dominating reproduction seed. Populations appear capable densifying if given opportunity,...
The family Cactaceae Juss. contains some of the most widespread and damaging invasive alien plant species in world, with Australia (39 species), South Africa (35) Spain (24) being main hotspots invasion. Global Cactus Working Group (IOBC GCWG) was launched 2015 to improve international collaboration identify key actions that can be taken limit impacts caused by cactus invasions worldwide. Based on results an on-line survey, information collated from a review scientific grey literature,...
Abstract Deciding whether to plant native or non-native trees in public urban green spaces is becoming complex and conflicted, decisions purely based on biotic nativeness are likely be hamstrung as climate change rising heat push many species beyond their natural ranges. Importantly, tree selection considerations by planners environmental managers will have move a primary focus securing conservation ecological outcomes, elucidate engage with growing interest the socio-cultural values...
This paper presents the first detailed assessment of invasive potential Melaleuca hypericifolia Sm. in South Africa. woody, fire-adapted shrub, native to Australia, is considered a high risk invader which could potentially occupy 4% country if allowed spread. As such, it listed under African legislation. known have naturalised at five sites Western and Eastern Cape Africa several introduced but non-spreading populations represent further invasion. An integrated management approach involving...
Abstract The idea of which species are native, based on their biogeographic origin, is central to many policies and programmes. Yet definitions contested the meanings ‘nativeness’ often complex confusing for people. For example, a plant that would be considered 'native' in Australia might have native bioregion thousands kilometres from given garden planting. nativeness culturally constructed connotes different contexts. As conservation research practice increasingly incorporate human values...
This research provides the first detailed assessment of Cistus ladanifer, a woody, perennial shrub native to Mediterranean, as an invasive species in South Africa. Three small naturalising populations (all less than 0.1 ha) this were discovered 2012 heathland vegetation ("Fynbos") Western Cape Province Prior discovery, C. ladanifer had not previously been recorded or recognised It poses significant threat local endemic vegetation, largely due its pre-adaptation similar environmental...
