Bloomfield, N. (2020). The wicked risks of biosecurity: Invasive species in Australia. Retrieved 12 March 2020, from https://phys.org/news/2020-02-wicked-biosecurity-invasive-species-australia.html
The Australian continent has been the host for countless invasive species, including the infamous cane toad and tramp ant. These non native species have the potential to harm both the Australian environment and economy. Biosecurity is a developing system in Australia and New Zealand that addresses the risk of pests entering the borders. Biosecurity risks are often complex and changing. As a result, so does the management of these risks. In Australia, biosecurity precautions range from fumigating imports to post border surveillance. The article emphasizes the importance of a well informed public to properly protect Australia from biosecurity threats, like the Asian black spined toad. Early reports of the invasive toad allowed agricultural agencies to eradicate the species before it became established.
I believe Australia’s vulnerability to invasive species is comparable to California. Like California, Australia’s large borders and niche ecosystems increase the frequency and severity of invasive species. Using Australia’s biosecurity system as a model, I think California should also focus on informing the public and agricultural sector about invasive species and encourage the public to report sightings of introduced species. However, Australia’s use of fumigation would be less applicable as many invasive species enter California through produce rather than goods.
I totally agree with your comparison of California and Australia when it comes to the issue of invasive species. Moreover, I think your identification of large boarders and niche ecosystems being key roles in the issue to be an adapt response. I would add however, that beyond niche ecosystems, California has swaths of area that mimic other habitats across the world closely. Examples of this are rolling hills towards the central valley that are similar to areas in the Mediterranean. Because of these similarities, it makes it easier for some invasive species to settle down.
That’s a great point that I failed to realize earlier. The deserts and forests of California are incredibly sensitive to invasive species. This mimicry may be contributing to California’s vulnerability.
I totally agree with concern about California native species being taken over by invasive species. Invasive species reek havoc everywhere. People are normally unaware of the fact that invasive species balanced ecosystems all over, and therefore, it is hard to stop invasive species from taking over. I think that it is really important to educate people on the downfall of endangered species taking over ecosystems.
