This map shows areasthat contain the largest concentrations of rare <strong>and</strong> potentially endangered species. (Data from State NaturalHeritage Programs, the Nature Conservancy, <strong>and</strong> Association for Biodiversity Information)the survival <strong>and</strong> recovery of each listed species. So farcritical habitats have been established for only aboutone-third of the species on the ESA list, mostly becauseof political pressure <strong>and</strong> a lack of funds. Beginning in2001 the Bush administration stopped listing newspecies <strong>and</strong> designating critical habitat for listedspecies unless required by court order.Getting listed is only half the battle. Next, theUSFWS or the NMFS is supposed to prepare a plan tohelp the species recover. By 2004, final recovery planshad been developed <strong>and</strong> approved for 79% of the listedendangered or threatened species in the United States.Examples of successful recovery plans include thosefor the American alligator, the gray wolf, the bald eagle,<strong>and</strong> the peregrine falcon. Bad news. About half ofcurrent recovery plans exist only on paper, mostly becauseof political opposition <strong>and</strong> limited funds.Should the Government CompensateL<strong>and</strong>owners When Endangered SpeciesDecrease the Economic Value of <strong>Their</strong> L<strong>and</strong>?Private Versus Public Property RightsThere is controversy over whether the governmentshould compensate private property owners whosuffer financial losses when it restricts how they canuse their l<strong>and</strong> because of the presence of threatenedor endangered species.Critical habitats for more than half of the listed endangered<strong>and</strong> threatened species in the United States arefound on private l<strong>and</strong>. One controversy over the ESAis the political <strong>and</strong> legal issue of whether federal <strong>and</strong>state governments must compensate private propertyowners when government laws or regulations limithow the owners can use their property <strong>and</strong> decreaseits financial value. Many people who own l<strong>and</strong> onwhich threatened or endangered species live think thelaw goes too far <strong>and</strong> infringes on their property rights.The Fifth Amendment of the U.S. Constitutiongives the government the power, known as eminent domain,to force a citizen to sell property needed for apublic good. For example, suppose the governmentneeds some or all of l<strong>and</strong> you own for a road. It canlegally take your l<strong>and</strong> but must reimburse you basedon the l<strong>and</strong>’s fair market value.The current controversy is over whether the Constitutionrequires the government to compensate youif instead of taking your property (a physical taking) itreduces its value by not allowing you to do certainthings with it (a regulatory taking). For example, youmight not be allowed to build on some or all of yourproperty or to harvest trees from your l<strong>and</strong> becausethese areas are habitats for an endangered species.This can decrease the value of one’s property. Forexample, a property owner in Travis, Texas, saw herl<strong>and</strong> decrease in value from $830,000 to $38,000 becauseit contained two endangered bird species: theblack-capped vireo <strong>and</strong> the golden-cheeked warbler.Should she be compensated for this loss by the federalgovernment?242 CHAPTER 12 Sustaining Biodiversity: The Species Approach
