Anthropogenic disturbances play an important role in invasibility, and the traits of exotic species act as mediators of invasion success. The impact of exotic species can be evaluated through an association with invasion potential. The magnitude and potential severity of exotic species impacts can aid in decision making regarding the best conservation, restoration, management and control actions. In this sense, our objectives were to (1) evaluate the potential invasion risk of naturalized graminoid species in the Cerrado biome using risk analysis; (2) understand the magnitude of the impact of these species on protected areas by analysing the relationships between invasiveness, invasion potential and proximity to strictly protected areas, as well as to the biome as a whole; and (3) identify the drivers of spread contributing to species richness and abundance in the Cerrado. Our results showed that naturalized graminoid species in the Cerrado biome present invasion risks and potential impacts varying from medium to high. Additionally, these landscapes were vulnerable due to their proximity to protected areas, which act as filters against these species and against anthropogenic agents (human population and road density) that may increase the richness and population sizes of these plants. Based on our results, we recommend developing and prioritizing management and control strategies in strictly protected areas and in their surrounding areas to avoid the dispersal and establishment of aggressive species (African grasses) in their interiors, homogenization risks and the consequent loss of native biodiversity.

人为干扰在入侵中起着重要作用，外来物种的特征充当入侵成功的中介。外来物种的影响可以通过与入侵潜力的关联来评估。外来物种影响的程度和潜在严重性可以帮助做出有关最佳保护，恢复，管理和控制措施的决策。从这个意义上讲，我们的目标是（1）使用风险分析评估塞拉多生物群落中归化的类粉虱物种的潜在入侵风险；（2）通过分析入侵性，入侵潜力和与严格保护区以及整个生物群落之间的关系，了解这些物种对保护区的影响的程度；（3）确定导致塞拉多物种丰富和丰富的传播动因。我们的结果表明，塞拉多生物群落中的归化类禾本科动物存在入侵风险，潜在影响从中到高不等。此外，由于这些景观靠近保护区，因此很容易受到破坏，而这些保护区可作为对这些物种和人为因素（人口和道路密度）的过滤器，可能增加这些植物的丰富度和种群规模。根据我们的结果，我们建议在严格保护的区域及其周围地区制定管理和控制策略并确定优先级，以避免在其内部散布和建立侵略性物种（非洲草），同质化风险以及随之而来的自然生物多样性丧失。
