Abstract:

This study estimates the willingness-to-pay (WTP) for a project (i.e. the Working for Water Programme) aimed at removing alien vegetation and restoring indigenous vegetation in Underberg, KwaZulu-Natal, South Africa. The WTP estimate reflects the benefit of preference for indigenous vegetation over alien vegetation. In a survey, a questionnaire was administered to 260 households in the Underberg region during September 2005. It was deduced that the mean WTP for the project was R21.12 in 2005 (R26.40 in 2008), the total WTP was R25 344.00 (R31 680.00 in 2008) and the WTP per hectare was R21.87

Abstract:

Background Globally, and in the Cape Floristic Region of South Africa, extreme fires have become more common in recent years. Such fires pose societal and ecological threats and have inter alia been attributed to climate change and modification of fuels due to alien plant invasions. Understanding the flammability of different types of indigenous and invasive alien vegetation is essential to develop fire risk prevention and mitigation strategies. We assessed the flammability of 30 species of indigenous and invasive alien plants commonly occurring in coastal fynbos and thicket shrublands in rela

Abstract:

Although most of the lowland endemic forests of the mountainous Indian Ocean island of La Réunion have been converted by Man to other land-uses, relatively intact ecosystems still survive at higher elevations. Given the particular conservational value of these remnants of primary forest, detailed knowledge of the threats faced by these native ecosystems was urgently needed. Accordingly we conducted field surveys through the various plant communities on the island in order to answer particular questions regarding the vulnerability of native vegetation remnants to invasive, introduced plant spec

Global influence of the wealthiest countries drives trends in crop diversity in the developing countries. In many countries, European colonization resulted in cultural disintegration and erosion of indigenous knowledge that made citizens lose interest in their own cultural heritage and adopt imperial know-how. During the same time, native biodiversity that was once maintained by the tradition it shaped declined. Alien crops prospered and finally dominated landscapes. In this paper, I looked at the apparent decline of indigenous crop diversity in Rwanda in the light of the “cultural disturbance

Glossy buckthorn (Frangula alnus Mill.) is an alien species in Canada that is invading many forested areas. Glossy buckthorn has impacts on the biodiversity and productivity of invaded forests. Currently, we do not know much about the species’ ecology and no thorough study of its distribution in temperate forests has been performed yet. As is often the case with invasive plant species, the phenology of glossy buckthorn differs from that of other indigenous plant species found in invaded communities. In the forests of eastern Canada, the main phenological difference is a delay in the shedding o

This paper describes a Catchment Management System (CMS) that provides objective procedures for managing fire. Prescribed burning is carried out in the mountain catchments of the Cape Province, South Africa, to enhance water yield, to rejuvenate the indigenous shrubland vegetation, to reduce fire hazard and to control invasive alien plants. Fire is the only practical tool for achieving these aims in the mountainous terrain. Recent research has improved understanding of the response of these systems to fire, but managing fire to achieve goals is very difficult. The CMS comprises a central geogr

Abstract:

The preservation of biological diversity is impossible without the preservation of natural vegetation. Changes in physical and geographical conditions, succession of phytocenoses, lead to transformation of growing conditions and loss of ecological niches by species. Simultaneously with these processes, the number of alien species increases. Their expansion is facilitated by violations of habitats with natural vegetation cover. Surveys of the slopes of mount Mashuk revealed the distribution of 30 alien species of tree flora from 17 families. Half of them overcame the restrictions of reproductio

Abstract. In South Africa the invasion of riparian forests by alien trees has the potential to affect the country's limited water resources. Tree water-use measurements have therefore become an important component of recent hydrological studies. It is difficult for South African government initiatives, such as the Working for Water (WfW) alien clearing programme, to justify alien tree removal and implement rehabilitation unless hydrological benefits are known. The objective of this study was to investigate the water use (transpiration rates) of a selection of introduced and indigenous tree spe

Abstract:

The vines Echinocystis lobata and Parthenocissus quinquefolia are spreading over the natural vegetation in riparian zones, which may significantly affect riparian vegetation properties and the quality of litter for aquatic organisms. We examined leaf morphological, biochemical and optical traits of these invasive alien species, each paired with its host, the willows Salix caprea and S. fragilis, respectively. The vines altered the host radiation environment and the amount of photosynthetic pigments. Both vines had significantly higher specific leaf area and lower leaf tissue density compared t

We compiled and analysed data from 1987?2004 on vegetation monitoring during feral ungulate management at Hakalau Forest National Wildlife Refuge, a tropical montane rainforest on the island of Hawai?i. All areas in the study had previously been used by ungulates, but cattle (Bos taurus) were removed and feral pig (Sus scrofa) populations were reduced during the study period. We monitored six line-intercept transects, three in previously high ungulate use areas and three in previously low ungulate use areas. We measured nine cover categories with the line-intercept method: native ferns; native

The abundance of two related species of the genus Kellicottia , the alien Kellicottia bostoniensis (Rousselet, 1908) and the indigenous K. longispina (Kellicott, 1879), was analyzed in dedicated communities in 2013-2017. The greatest abundance of the alien species was noted in zooplanktocenoses of mesotrophic water bodies (the Serezha River and Lake Svyato).

Growing numbers of alien plant species threaten natural ecosystems worldwide. Mexico, as a megadiverse country, has lower numbers of alien species than other regions in America. However, there is a lack of information on the factors that determine the diversity patterns of alien species and their relative importance in the vegetation. The diversity of alien roadside herbs was analysed along an elevational gradient in western Mexico, including their relationship with environmental factors. Three hundred and seventeen herbaceous species were found in 37 sampling sites; 10% were aliens. The propo

Abstract:

The Chicana lesbian writer Gloria Anzaldúa believed that indigenous spirituality could be carried in the mixed-race ‘blood’ of the mestiza, and tapped into psychically. This psychic access could then bring up, as if from the depths of time, an authentically indigenous, if alien, soul-sensibility into the mestiza consciousness and thus into the present. Following Suzanne Bost, I think of this process as a way of ‘feeling pre-Columbian’. I argue that Anzaldúa used this feeling to queer the notion of historical change through a long and inaccessible time as, instead, a spatial and therefore cross

The vegetational landscape of north-easternTerairegion at the foot hills of Central Himalayas is a mosaic of grassland, old-field, wasteland, and forest ecosystems. Like many other parts of the country, this region is also infested with alien intruders which not only interfere with the growth and production of food crops but also exercise adverse effects on the biodiversity of native species. The present study attempts to catalogue the invasive alien species of the terrestrial vegetation of north-eastern Uttar Pradesh especially with reference to their habit, taxonomic position, and nativity.
