Judging Adaptive Management Practices Of U.S. Agencies, Robert L. Fischman, J. B. Ruhl Apr 2016

Judging Adaptive Management Practices Of U.S. Agencies, Robert L. Fischman, J. B. Ruhl

Articles by Maurer Faculty

All U.S. federal agencies administering environmental laws purport to practice adaptive management (AM), but little is known about how they actually implement this conservation tool. A gap between the theory and practice of AM is revealed in judicial decisions reviewing agency adaptive management plans. We analyzed all U.S. federal court opinions published through 1 January 2015 to identify the agency AM practices courts found most deficient. The shortcomings included lack of clear objectives and processes, monitoring thresholds, and defined actions triggered by thresholds. This trio of agency shortcuts around critical, iterative steps characterizes what we call AM-lite. Passive AM differs …


Lessons From Pollution Control: Response To Heller And Hobbs 2014, Robert L. Fischman, James Salzman Jun 2015

Lessons From Pollution Control: Response To Heller And Hobbs 2014, Robert L. Fischman, James Salzman

Articles by Maurer Faculty

Heller and Hobbs (2014) provide an incisive analysis of the challenges inherent in setting endpoint states as conservation goals. The social construct of nature, nonequilibrium ecosystems, global climate change, large-scale transformations of the landscape, and increasing population and economic activity confound efforts to establish conservation goals. Stakeholders often disagree on endpoint targets, whereas competing notions of historic fidelity and future flexibility frustrate our ability to articulate success, never mind actually achieve it. As Heller and Hobbs describe, this leaves managers in the bind of finding the “balance between future-looking management emphasizing change and past-looking management emphasizing persistence.” As a result, …


Learning From Conservation Planning For The U.S. National Wildlife Refuges, Robert L. Fischman, Vicky J. Meretsky Oct 2014

Learning From Conservation Planning For The U.S. National Wildlife Refuges, Robert L. Fischman, Vicky J. Meretsky

Articles by Maurer Faculty

The U.S. National Wildlife Refuge System has nearly completed its first round of unit-level, comprehensive conservation plans (CCPs) and will soon begin required revisions. Laws and policies governing refuge planning emphasize ecological integrity, landscape-scale conservation, and adaptive management. We evaluated 185 CCPs completed during 2005–2011, which cover 324 of 555 national wildlife refuges. We reviewed CCP prescriptions addressing 5 common conservation issues (habitat and game, nongame, imperiled, and invasive species) and 3 specialized topics (landscape-scale conservation, climate change, and environmental quality). Common conservation issues received prescriptions in >90% of CCPs. Specialized topics received more variable treatment. Prescriptions for aquatic connectivity, …


Statutory Reform To Protect Migrations As Phenomena Of Abundance, W. William Weeks, Jeffrey B. Hyman, Andrea Need Jan 2011

Statutory Reform To Protect Migrations As Phenomena Of Abundance, W. William Weeks, Jeffrey B. Hyman, Andrea Need

Articles by Maurer Faculty

Animal migrations capture the human mind and heart like few other natural phenomena. Migrations provide ecological, psychological (e.g., aesthetic), cultural, and economic benefits. Increasingly, though, migrations are being recognized as threatened phenomena-that is, spectacular aspects of the life history of animal species often involving large numbers of individuals, but which are threatened with impoverishment or demise, even though the species per se may not be in peril. Migration phenomena are themselves worthy of protection, as a category of biodiversity Yet, conserving migratory populations and their migrations is particularly problematic. Migratory animals are especially vulnerable to a variety of threats because …


A Tradable Conservation Easement For Vulnerable Conservation Objectives, W. William Weeks Jan 2011

A Tradable Conservation Easement For Vulnerable Conservation Objectives, W. William Weeks

Articles by Maurer Faculty

The critical conservation objectives in some conservation easements will probably be compromised by the effects of climate change in the relatively near future. Prompted to consider that likelihood, we can similarly predict that landscape fragmentation, invasive species, and other catastrophes— anthropogenic and natural—may also seriously diminish the capacity of particular parcels of land to serve narrowly defined conservation purposes, and especially, the conservation of a particular element of biodiversity.


The Role Of Riparian Water Law In Protecting Biodiversity: An Indiana (Usa) Case Study, Robert L. Fischman Jan 1997

The Role Of Riparian Water Law In Protecting Biodiversity: An Indiana (Usa) Case Study, Robert L. Fischman

Articles by Maurer Faculty

This article discusses how the rules affecting the use of surface water ground water in a typical riparian state, Indiana, can promote the conservation biological diversity. The article first surveys the basic water laws that apply to surface water, diffused surface water, underground streams, and ground water. The rules governing the uses of these waters originate in common law property doctrines and substantially clarified by state legislation. Next the article considers state administration of water. The article examines regulatory tools and administrative opportunities control uses of water in a manner that protects biodiversity. Programs requiring permits for construction in floodplains, …
