Management Information
Mechanical: Mechanical control of Rubus niveus is difficult because the entire plant must be thoroughly removed to prevent regeneration. This is typically only successful when the plants are still small seedlings. The cutting back of plants may also be used as an initial step to chemical control (Starr et al. 2003). Chemical: Motooka et al. (2003) found triclopyr ester in a crop oil carrier (either as drizzle applications at 1 lb./acre or as very low volume basal bark applications at a 15% concentration) to be successful in the management of R. niveus. They note that the species is supposidly resistant to triclopyr ester when water is the carrier. Applications of a 2% Roundup solution are suggested by the Charles Darwin Foundation for the Galapagos Islands (Renteria et al., 2006). More recently solutions of picloram have been found to be more persitant. Biological: The use of fungal pathogens for biological control of R. niveus is being explored, with Phragmidium barclayi Dietel, Phragmidium himalense J.Y. Zhuang, Phragmidium octoloculare Barclay, Phragmidium shogranense Petr., and Pseucercospora sp. having been identified as fungal pathogens from the species' native range (Ellison and Barreto, 2004). Cultural: Alternative control methods are being trialled in Galapagos using species that prevent seed bank germination and reduce establishemtn. Introduced pasture such as Urochloa maximum, other Urochloa spp, and Pennisetum purpureum are useful. Coffee (Coffea arabica) is also being trialled.
Location Specific Management InformationFloreana Is. (Ecuador)
Rubus niveus is as yet less widespread on Floreana, Isabela and Santiago. Although it is unclear if eradication is possible, projects are underway in Santiago to at least control the known populations. At present control is carried out using glyphosate or picloram, both at 2%.
In 2007, detailed searching and control was started on Floreana to enable evaluation of the possibility of eradicating this species (Rachel Atkinson., pers.comm., July 2008). Rentería et al. (2007) documents costed eradication plans for 21 invasive species including Rubus niveus in Galapagos. The plans were developed as part of a GEF funded project ECU/00/G31 'Control of Invasive species in the Galapagos Archipelago'.
The management plans report projects at different stages of development and for species that have invaded to different extents. Three of the projects have already been finished successfully, 5 have yet to be started, and for the rest the projects have been running for between 1 and 6 years. The cost and time needed for eradication varies considerably by species and demonstrates the importance of species eradication as soon as possible after detection.

Resumen
El presente documento proporciona planes de manejo y el costo para la erradicación de 21 especies que se encuentran presentes en Galápagos. Los planes fueron desarrollados como parte del proyecto ECU/00/G31 "Control de las especies invasoras en el Archipiélago de las Galápagos", suscrito por el Gobierno Ecuatoriano, representado por el Ministerio del Ambiente, con el Fondo para el Medio Ambiente Mundial (GEF). El Proyecto es implementado por el Programa de las Naciones Unidas para el Desarrollo (UNDP), tiene como instituciones ejecutoras al Servicio Parque Nacional Galápagos (SPNG), Instituto Nacional Galápagos (INGALA), Servicio Ecuatoriano de Sanidad Agropecuaria-Galápagos (SESA-Galápagos), y Fundación Charles Darwin (FCD). Los planes de manejo representan proyectos en diferentes estados de desarrollo y dimensión. Tres de estos proyectos ya han sido desarrollados completamente, trece están en proceso y cinco aún no se han iniciado. El costo y tiempo para la erradicación varia considerablemente según la especie y se muestra la importancia económica que implica desarrollar proyectos de erradicación tan pronto las especies son detectadas.
