一般影响 香泽兰会密集生长，其竞争压力与异株克生效应，会抑制其它植物的生长空间。栖地受干扰时才有机会入侵。天候干燥时，是助长野地发生火灾的燃料之一 (PIER, 2003)。对过敏的人来说，香泽兰也会引起皮肤不适或气喘等征状。在耕地与适于种植农作物的土地中它是主要的杂草, 包括橡皮、油棕、林业与咖啡的耕地。 C. odorata也是一个国家公园的杂草。在南非圣露西雅洼地公园，它被指会干扰自然生态系统。筑巢尼罗河鳄鱼 (请参阅Crocodylus niloticus在 IUCN 红皮书 ) 需要开放、晴朗, 沙地在哪里产卵。 C. odorata会遮蔽、占去筑巢地点，其纤维的簇根不适于蛋室与筑巢工程。以及改变这个自然栖息地， C. odorata的树荫会使水温降低，低温会影响任何已经建好的巢，会使得产下的后代大多是雌性，可能也会阻碍许胚胎发展(Leslie and Spotila 2001)。          地点特有的影响： Greater St Lucia Wetland Park (South Africa)   生态系统变化: Chromolaena odorata is reported to interfere with natural ecosystem processes in the Greater St. Lucia Wetland Park. Nesting Nile crocodiles (see Crocodylus niloticus in IUCN Red List of Threatened Species) require open, sunny, sandy areas in which to deposit their eggs. C. odorata shades and overtakes nesting sites creating fibrous root mats unsuitable for egg chamber and nest construction. As well as altering this natural habitat C. odorata produces shade resulting in colder temperatures in any nests that do get constructed, an effect that produces a female-biased sex ratio in the offspring as well as perhaps preventing embryonic development altogether (Leslie and Spotila 2001).
