The Difficult Problem Of Nonpoint Nutrient Pollution: Could The Endangered Species Act Offer Some Relief?, Zdravka Tzankova
The Difficult Problem Of Nonpoint Nutrient Pollution: Could The Endangered Species Act Offer Some Relief?, Zdravka Tzankova
Zdravka Tzankova
Nutrient pollution of rivers, streams, lakes, and estuaries is one of the preeminent water quality issues in the United States today, and poses a significant threat to the health of aquatic ecosystems. Agricultural nonpoint discharges, the runoff of nitrogen and phosphorous from animal manure and chemical fertilizers, are the primary sources of such nutrient pollution.
A pervasive and long-standing problem, nonpoint pollution, nutri- ent and otherwise, has proven to be one of the toughest challenges in contemporary environmental regulation. This situation is significantly attributable to the political and administrative dynamics of fragmented regulatory authority. The power to control such nonpoint …

Can The Esa Address The Threats Of Atmospheric Nitrogen Deposition? Insights From The Case Of The Bay Checkerspot Butterfly, Zdravka Tzankova, Dena Vallano, Erika Zavaleta
Zdravka Tzankova
The Bay Checkerspot Butterfly reached its threatened status largely as a result of habitat loss through development. The species now benefits from the habitat pro- tection powers of the Endangered Species Act, yet the biggest new hazard to the survival of remaining Bay Checkerspot Butterfly populations may come from atmospheric nitrogen deposition. Driven by combustion and agricultural emissions, such deposition is an important cause of change in ecosystem structure and function, including potentially critical changes in the remaining Bay Checkerspot Butterfly habitat. We use the Bay Checkerspot Butterfly case to examine whether the Endan- gered Species Act, as it currently …
The Political Consequences Of Legal Victories: Ballast Regulation And The Clean Water Act, Zdravka Tzankova
The Political Consequences Of Legal Victories: Ballast Regulation And The Clean Water Act, Zdravka Tzankova
Zdravka Tzankova
Federal conservation policy has seen a new development recently: the use of the Clean Water Act (CWA) as a tool for regulating ballast water discharges from ships and, thereby, for preventing biological invasions caused by the discharge of nonindigenous organisms in ballast. Some outcomes of this new method for regulating ballast water discharge are obvious, others are much less so. Superimposing CWA regulatory authority on an already existing system of U.S. ballast law and regulation is likely to change the politics of ballast regulation. What do such changes in regulatory politics spell for the future of regulatory protections against biological …
The Science And Politics Of Ecological Risk: Bioinvasions Policies In The Us And Australia., Zdravka Tzankova
The Science And Politics Of Ecological Risk: Bioinvasions Policies In The Us And Australia., Zdravka Tzankova
Zdravka Tzankova
The US and Australia – western democracies with similar histories of public awareness on environmental issues and broadly comparable records of policy and regulatory action to safeguard environmental quality – have responded differently to one of the newest and most significant threats to marine bioidiversity: that of biological invasions mediated by the ballast water of commercial shipping. Each country has framed the same invasion risks differently for the purposes of policy and regulation: Australia has decided to use a more narrowly circumscribed, target-species-based approach whereas US policy and regulation takes a more comprehensive and precautionary approach. These somewhat surprising national …

This Article analyses the U.S. Conference of Catholic Bishops’ statement, Forming Consciences for Faithful Citizenship: A Call to Political Responsibility from the Catholic Bishops of the United States, and how it addresses the economic and environmental issues raised during the 2008 Presidential election.
