of native fish and decrease the amount of available catches. Also, the bait that fishermen use can contain invasive species, so they must be mindful of what they are introducing into the water. Fisheries can be similarly affected by the spread of invasive species, and care must be taken to avoid initiating a fishery with a non-native species. Since fisheries produce only certain species of fish, these monoculture populations are especially vulnerable to threats. Those in the timber and agricultural industries need also be conscious of invasive species, even if they are aquatic. Protecting terrestrial resources helps maintain greater ecological health, and the BLM and the Forest Service are involved with the Task Force. Finally, the public and recreationalists must be educated about the threat of spreading invasive species. Because people have been known to release exotic pets into their local waters, and take their boats from location to location, they need to be aware of the risks involved with these behaviors. Evaluations NISA is only one of a few federal laws aimed specifically at preventing the introduction and spread of non-native invasive species. Its scope was broader than its predecessor, NANPCA, and it initiated a number of new strategies aimed at promoting collaboration, research, and education, which have actually been more successful than the guidelines and regulations put forth. Many agree that there is much room for improvement. One major criticism of NISA is that it does not reach far enough. By focusing so heavily on ballast water, it neglects other significant pathways of invasive species introductions, as well as geographic locations that are not common sites for transoceanic trade. Increasing populations and travels around the world contribute to the risk of introducing non-native species, and these issues must be addressed if better management and control are expected. Research from the Task Force could be used to further NISA, if it were to be reauthorized. Another criticism of NISA is that its underlying principles need adjustment. Since it narrowly addresses ballast water and individual invasive species, it fails to examine and take into account the environment as a whole. Historically, the way to manage environmental damage was to limit that damage to a certain threshold; action would only be taken if the threshold was breached, and this was how NISA was structured. A different approach would be to use the precautionary principle to prevent introductions: if an activity carries
