The Prosopis julifloraâProsopis pallida complex: a monograph, Putting knowledge on Prosopis into use in Kenya. Countries that use only chemical and mechanical control are mainly found in the Middle East and have small isolated invasions and are usually wealthier nations, whereas control through utilization is applied in poorer countries such as Kenya and Ethiopia. âBoon or baneâ (Tiwari 1999), âPest or providence, weed or wonder tree?â (Pasiecznik 1999), âInvasive weed or valuable forest resource?â (Pasiecznik 2002). Styles emerge from most flowers prior to anthesis but they are probably not receptive at this stage and the flowers remain in this state for some days. The height of P. glandulosa trees has been used successfully to estimate the depth of the water table in the USA (Simpson, 1977). Birds, bats, reptiles and ants also feed on Prosopis spp. Mechanical cleaning of Prosopis seed. The all-embracing, collective P. juliflora concept of Bentham (1875) including P. glandulosa and several other species was maintained by other botanists for over a century and, although currently rejected by most taxonomists and researchers, it is still used occasionally to this day. The following case studies were selected as being representative of different management strategies and also encompass the approaches most commonly employed in countries with different levels of socioeconomic development (developedâAustralia; emerging economiesâSouth Africa; developingâKenya). Technical Bulletin, Agricultural Research Service, United States Department of Agriculture, No. In: Simpson BB, ed. http://plants.usda.gov/, USDA-NRCS, 2002. This paper presents a global review of Prosopis, focusing on its distribution, impacts, benefits and approaches to management. Kingsville, Texas, USA: Center for Semi-Arid Forest Resources, 4.3-4.20, Hodkinson ID, 1991. The following Supporting Information is available in the online version of this article â. In general, most landowners use mechanical and chemical control measures to manage Prosopis. The promotion of biofuels could also lead to the spread of invasive woody species such as Prosopis (Witt 2010). Developmental host-specificity of Mozena obtusa (Heteroptera: Coreidae), a potential biocontrol agent for Prosopis species (mesquite) in Australia. A later study by Park et al. Methods for literature review, climate matching, regression analysis, classification and regression tree. Recently, a new utilization approach to increase invasive Prosopis use has been adopted in Kenyaâa power station (based on technology from India) is currently being built in the Kenyan Rift Valley which aims to produce electricity for the local area from burning Prosopis biomass (S. Choge, pers. Leaves bipinnate, glabrous, 1-2 pairs of pinnae per leaf, up to 15 cm long. 29 (3), 157-165. There have been numerous misidentifications of introduced Prosopis species, especially in Africa. Psyllids are known to severely affect the growth of Prosopis (Hodkinson, 1991) and have been suggested for use in controlling invasions. 2007). BSc Thesis, University of Wales, Bangor, UK, Pasiecznik NM, 2006. Native weedy Prosopis taxa are also estimated to cause a loss of US$200â500 million per annum to the livestock industry in the USA (DeLoach 1984). Archer, 1995), who suggest that the first trees that establish on arid land are Prosopis spp. Noxious Range Weeds. Logistic regression highlighting the importance of different ecological, economical and social factors in determining management of Prosopis within a country. Underlying information on Prosopis invasions worldwide. Native biodiversity in many parts of the world has also been negatively impacted by invasive Prosopis species (Steenkamp and Chown 1996; Dean et al. Trees have been noted to fix nitrogen under conditions of high salinity and high water deficits (Felker et al., 1981). Department of Botany and Zoology, Centre for Invasion Biology, Private Bag X1. Prosopis is commonly used for fuel, fodder, windbreaks, shade, construction materials and soil stabilization through its invasive ranges in Africa and Asia (Pasiecznik et al. Although very widely introduced around the world, P. glandulosa is most common as an invasive weed in Australia and southern Africa. Time scale of all Prosopis introductions globally (n = 82 known speciesâcountry introduction dates). For example, Ansley et al. Physical protection is offered from the sun by a wide crown, and the thorns and shrubby form can offer excellent protection from large predators. Country-specific strategic plans need to be created as there are large differences in invasion rates and scales and socio-economic situations within different areas of the world. A very prostrate form that rarely even becomes a shrub was given varietal rank by Burkart, and P. glandulosa var. 2014). Flowering time has evolved variously, with legume production generally coinciding with the beginning of the wet season for improved water dispersal and seedling establishment, or the beginning of the dry season, ensuring increased pod consumption and seed dispersal by wild animals. Three seed-feeding beetles (A. prosopis, A. bottimeri and Neltumius arizonensis) were introduced as biological control agents to try and reduce spread while maintaining its benefits (Zimmermann 1991; Coetzer and Hoffmann 1997). However, studies on the ecology of spread in Australia (van Klinken et al., 2005) conclude that stands will continue to increase in area and density, and no self-thinning is expected to occur unlike that shown to happen in native range invasions, on the assumption that conditions are different. glandulosa), PRCJT (Prosopis juliflora var. 2011). 2012). J.]. In arid and semi-arid zones it is particularly important that seeds are dispersed to sites with preferable water status. 2011). torreyana from New Mexico to California, USA, and adjacent areas of Mexico are similar and not always separable from sympatric Prosopis species. We review the literature and collate data from many sources. P. glandulosa is a declared noxious weed in Australia and South Africa, and the genus as a whole is regulated in several other countries. Hard seed coats will also degrade over time and older seed that is still viable tends to germinate without pre-treatment (Pasiecznik and Felker, 1992). – honey mesquite Variety: Prosopis glandulosa Torr. They alter ecosystem services such as water supply, hydrological functioning, grazing potential and soil quality (DeLoach 1984; Bedunah and Sosebee 1986; Archer 1989; Le Maitre et al. Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. In Felker P, Moss J, eds. The firewood is of excellent quality, and imparts a pleasant flavour to food cooked over it, and P. glandulosa charcoal ('mesquite coals') is traded commercially throughout the USA for the barbeque industry. It is crucial to understand the reasons for introductions, uses (benefits), costs, ecology and scales of invasions and to elucidate perceptions and potential contentious issues when creating sustainable management plans (Kull et al. The case studies are also characteristic of management strategies driven and implemented by different stakeholders, e.g. 2012). Prosopis cover increased by â¼35 % between 1996 and 2008, despite the expenditure of R435.5 million (US$42.7 million) on control over this period. Washington, DC, USA: US National Academy of Sciences, Schachtschneider K, February EC, 2013. P. glandulosa has been widely introduced and planted as a fuel and fodder tree. The product simultaneously leads to reduced muscle inflammation, which leads to accelerated regeneration. comm.). 2006a). 2011). Martínez-Ávila GC(1), Hernández-Almanza AY(1), Sousa FD(2), Moreira R(2), Gutierrez-Sanchez G(3), Aguilar CN(4). Changes in land-use systems in the spread of Prosopis (D'Antoni and Solbrig, 1977) and the rapid expansion in areas invaded, are likely to be more important that climatic change. The genus Prosopis in southern Africa. In Yemen there is no evidence that the non-native A. prosopis feeds on the native Prosopis cineraria (Al-Shurai and Labrada 2006). Aspects of the biology and the host range of this seed-feeding weevil were studied in Argentina and South Africa to evaluate its potential as a biocontrol agent, and field surveys found that the beetle was responsible for 51% of the seed damage on P. flexuosa with a host range restricted to Prosopis species in section Algarobia. It is considered to have a medium growth rate. The Prosopis juliflora is a species growing in Jamaica which I should be very glad to get seed of". Prosopis glandulosa and over 1000 other quality seeds for sale. Livestock production can be significantly improved if conditions allow for understorey management. glandulosa and other Prosopis species, but no records as to their performance are available (Raizada and Chatterji, 1954). El mezquite: el árbol del desierto. Selección y manejo de material reproductivo de mezquite (Prosopis spp.). Jacoby and Ansley, 1991; Zimmerman, 1991). torreyana, P. velutina and P. articulata), algarrobo (P. chilensis), kiawe (P. pallida) and tamarugo (P. tamarugo) grown in sand culture on nitrogen-free media. Willd.) However, most of the widespread introductions were made into Africa and Asia between the 1970s and 1990s (Fig. 3) as part of reforestation programmes after major droughts in the Sahel. Prosopis: Semiarid Fuelwood and Forage tree; Building Concensus for the Disenfranchised. glandulosa Prosopis glandulosa var. torreyana), Highly adaptable to different environments, Tolerates, or benefits from, cultivation, browsing pressure, mutilation, fire etc, Has propagules that can remain viable for more than one year, Highly likely to be transported internationally deliberately. honey mesquite. Kingsville, Texas, USA: Center for Semi-Arid Forest Resources. 2011; Stark et al. Screw bean is named for its spirally twisted pods, which are popular in dried arrangements. The PLANTS Database., Greensboro, North Carolina, USA: USA National Plant Data Team. Whereas it may be expected that the presence of impenetrable stands of P. glandulosa decrease biodiversity, the opposite can occur. Populations increased again when funding diminished, but in the mid-1970s the allocation of government funding led to substantial progress with clearing (van Klinken and Campbell 2009). There have also been conflicts of interest regarding which form of management to implementâhow best to preserve, exploit and even enhance benefits while reducing negative impacts of Prosopis invasions (Zimmermann 1991). Natural enemies of species of Prosopis native to the Americas are well documented with over 945 phytophagous insect species recorded (Van Klinken et al., 2009). (2009) also illustrated a high climatic suitability for Prosopis in southern and eastern Africa and showed that there are many areas that could have invasions but currently do not. The potential environmental damage from the widespread use of herbicides must also be taken into consideration. Scientific: Prosopis glandulosa Common: honey mesquite Family: Fabaceae (Leguminosae) Origin: Broadly distributed from the San Joaquin Valley of central California, Arizona, southwest corner of Utah and southern Nevada, southern New Mexico, Texas, south Oklhoma and even into Louisiana and then extending south into the Yucatan pennisula of Mexico. To date, there is no evidence of the success of control through utilization as a management technique (Table 2). Baton Rouge, USA: National Plant Data Center. Control of Prosopis first started in 1954 at Mardie Station, Western Australia, and by 1962 a major reduction in Prosopis density had been achieved. 2006a, b). 2, 1964. pp. Later introductions may have come from the Americas, or possibly from India or South Africa where Prosopis species had already become naturalized. 2001). Although P. pallida is invasive in many areas (Rejmánek and Richardson 2013), it appears to be less aggressive than some other species (Pasiecznik et al. Prosopis is een geslacht in de vlinderbloemenfamilie (Fabaceae). 14 in the arid zone series. Seed with the endocarp shell removed were common in the faeces of goats and cattle but rarely seen in the faeces of horses or foxes (Solbrig and Cantino, 1975). Catalogue of the recognized species of Prosopis. Requirements for research and management needs regarding Prosopis and factors limiting success. A South African perspective of Prosopis. It is generally accepted that whatever the initial introductions may have been, subsequent introductions of P. juliflora from an unknown source are now the dominant 'common mesquite'. A diagnostic key to the various forms of introduced mesquite (Prosopis juliflora DC).
