“…El uso excesivo de especies con importancia económica y de reforestación, así como el manejo inadecuado, aumenta su propagación y supervivencia en nuevos hábitats. Sin embargo, es indispensable llevar a cabo un plan manejo basada en las 26 especies invasoras más problemáticas en Centroamérica para el control y prevención (Rojas-Sandoval et al, 2022).…”

El Refugio de Vida Silvestre Barras Cuero y Salado es un área protegida que se ubica en la zona costera atlántica de Honduras. Sin embargo, esta área natural se encuentra amenazada por la introducción de especies y el cambio de uso de suelo por el cultivo de palma africana. El objetivo de este estudio fue determinar la flora vascular del refugio, especialmente las especies asociadas al bosque de manglar. Se evaluó el estado de conservación de 118 especies según los criterios de Lista Roja de la Unión Internacional para la Conservación de la Naturaleza (uicn). Se reportan 397 especies vegetales distribuidas en 101 familias y 292 géneros. Fabaceae es la familia más diversa con 45 especies, en su mayoría herbáceas. Se reportan cuatro especies de mangle: Avicennia germinans, Conocarpus erectus, Laguncularia racemosa y Rhizophora mangle, así como otras 47 especies en este ecosistema. Se evaluó el estado de conservación de 118 especies según los criterios de la Lista Roja de la Unión Internacional para la Conservación de la Naturaleza (uicn). Un total de siete especies están protegidas bajo el apéndice II de la Convención sobre el Comercio Internacional de Especies Amenazadas de Fauna y Flora Silvestres (cites). Aunque esta área presenta una considerable riqueza de plantas vasculares, la presencia de especies introducidas e invasoras es un indicador del impacto antrópico y la agricultura se considera como la principal amenaza del humedal.

“…Invasive plants can cause serious negative impacts to biodiversity, human health, and primary resource industries (Pyšek et al 2020;Ward et al 2021). The largest vector of new plant introductions and invasions is the global trade of ornamental plants, which is continually growing in reach and quantity (Weber et al 2008;Dodd et al 2015;Faulkner et al 2016;van Kleunen et al 2018;Arianoutsou et al 2021;Beaury et al 2021;Rojas-Sandoval et al 2022).…”

Weed wide web: characterising illegal online trade of invasive plants in Australia

Invasive plants seriously impact our environmental, agricultural and forestry assets, and the ornamental plant trade is a major introduction pathway. The variety and extent of ornamental plant trade is growing in reach and is increasingly facilitated by the internet (i.e., through e-commerce). A lack of surveillance and regulation of e-commerce has resulted in invasive species being widely traded on these platforms. Here, we investigated the illegal trade in invasive plant species occurring in Australia by collecting advertisements found on a popular e-commerce website. Across a 12-month period we found 155 plant taxa advertised online that were prohibited to trade in Australian. From 10,000 advertisements (4.25% of total advertisements found), we found 1,415 instances of these invasive plants advertised, of which 411 breached local jurisdictional (i.e., State or Territory) laws. Opuntia cacti and invasive aquatic plants were traded in the greatest quantities. A variety of uses for plants prohibited to trade were purported by sellers, where aquatic uses were the most popular (i.e., water filtering and habitat for aquatic animals). Despite Australia’s strict internal biosecurity regulations, we found that trade prohibitions had no influence on the quantity and price of illegal invasive plants traded. Given this, and the extent of illegal invasive plants traded, we believe increased monitoring and regulation of online plant trade is warranted. However, to obtain the most optimal outcomes, regulations should be coupled with increased cooperation from e-commerce platforms and public awareness campaigns. Future weed risk assessments should consider online trade as a key factor in the long-distance dispersal and propagule pressure of a plant. Jurisdictions would also benefit from greater alignment on plant trade prohibitions and revision of associated compliance policies.
