Humans as Global Plant Dispersers: Getting More Than We Bargained For: Current introductions of species for aesthetic purposes present the largest single challenge for predicting which plant immigrants will become future pests

讲一个公园有了很多non-indigenous species的植物，一些闲人认为是因为公园的游客太多造成的（不知道为什么，好像是说因为游客来玩儿破坏原有生态环境，形成了一些外来品种适合生长的环境）。这闲人举例说，比如，某某公园游客很多，也长了些杂草／非本地植物。这时，另一人跳出来说是公园本来的生态条件而非游人造成了异类植物繁殖，说某些大公园的生态本来就很多样化，从而造成杂草丛生。后来还举了例子，最后建议公园管理人员多去寻找并ｅｒａｄｉｃａｔｅ　ｗｅｅｄｓ，而不要限制人们游园。

Humans also play both accidental and deliberate roles in moving weeds around a continent, and conservation areas are certainly not immune to this dispersal. Conservationists have often expressed alarm at the capacity for visitors to bring weed seeds unwittingly on their vehicles or clothing into national parks. But this alarm has been raised with little careful investigation. Although seeds are often carried on vehicles or clothing, the significance of this movement for the growth and spread of weed floras in parks is still unknown. Suggestive evidence was provided by Macdonald and colleagues (1989). They showed that the number of visitors to North American and South African national parks was positively correlated with the number of exotic species. Lonsdale (1999) reanalyzed their data to correct for the fact that bigger parks, which most likely contain more environmental heterogeneity and thus could support more nonindigenous species, also would tend to have more visitors. Even after correcting for the effect of park size, the evidence supported the conclusion drawn by Macdonald and colleagues (1989). However, this result still does not mean that we are witnessing a direct effect of visitors bringing seeds into the parks—it could be that the pressure of hordes of visitors creates disturbances within the parks in which weeds can flourish (Lonsdale 1999). In any case, such information may have little significance for management. Lonsdale and Lane (1994) showed that most cars entering K**u National Park in tropical Australia had zero or one seed, suggesting that any attempt to institute quarantine screening of vehicles would result in largely fruitless searches. Resources, they contended, would be better directed at searching for and eradicating weed outbreaks in the park.
