§172. Wildlife-vehicle collision reduction and habitat connectivity improvement
23 U.S.C. § 172
Study.—
In general.— The Secretary shall conduct a study (referred to in this subsection as the “study”) of the state, as of the date of the study, of the practice of methods to reduce collisions between motorists and wildlife (referred to in this section as “wildlife-vehicle collisions”).
Contents.—
Areas of study.— The study shall—
update and expand on, as appropriate—
the report entitled “Wildlife Vehicle Collision Reduction Study: 2008 Report to Congress”; and
the document entitled “Wildlife Vehicle Collision Reduction Study: Best Practices Manual” and dated October 2008; and
include—
an assessment, as of the date of the study, of—
the causes of wildlife-vehicle collisions;
the impact of wildlife-vehicle collisions on motorists and wildlife; and
the impacts of roads and traffic on habitat connectivity for terrestrial and aquatic species; and
solutions and best practices for—
reducing wildlife-vehicle collisions; and
improving habitat connectivity for terrestrial and aquatic species.
conduct a thorough review of research and data relating to—
wildlife-vehicle collisions; and
habitat fragmentation that results from transportation infrastructure;
survey current practices of the Department of Transportation and State departments of transportation to reduce wildlife-vehicle collisions; and
consult with—
appropriate experts in the field of wildlife-vehicle collisions; and
appropriate experts on the effects of roads and traffic on habitat connectivity for terrestrial and aquatic species.
Report.—
In general.— Not later than 18 months after the date of enactment of the Surface Transportation Reauthorization Act of 2021, the Secretary shall submit to Congress a report on the results of the study.
a description of—
the causes of wildlife-vehicle collisions;
the impacts of wildlife-vehicle collisions; and
the impacts of roads and traffic on—
species listed as threatened species or endangered species under the Endangered Species Act of 1973 (16 U.S.C. 1531 et seq.);
species identified by States as species of greatest conservation need;
species identified in State wildlife plans; and
medium and small terrestrial and aquatic species;
an economic evaluation of the costs and benefits of installing highway infrastructure and other measures to mitigate damage to terrestrial and aquatic species, including the effect on jobs, property values, and economic growth to society, adjacent communities, and landowners;
recommendations for preventing wildlife-vehicle collisions, including recommended best practices, funding resources, or other recommendations for addressing wildlife-vehicle collisions; and
guidance, developed in consultation with Federal land management agencies and State departments of transportation, State fish and wildlife agencies, and Tribal governments that agree to participate, for developing, for each State that agrees to participate, a voluntary joint statewide transportation and wildlife action plan—
to address wildlife-vehicle collisions; and
to improve habitat connectivity for terrestrial and aquatic species.
Workforce Development and Technical Training.—
In general.— Not later than 3 years after the date of enactment of the Surface Transportation Reauthorization Act of 2021, the Secretary shall, based on the study conducted under subsection (a), develop a series of in-person and online workforce development and technical training courses—
to reduce wildlife-vehicle collisions; and
to improve habitat connectivity for terrestrial and aquatic species.
make the series of courses developed under paragraph (1) available for transportation and fish and wildlife professionals; and
update the series of courses not less frequently than once every 2 years.
Standardization of Wildlife Collision and Carcass Data.—
Standardized methodology.—
In general.— The Secretary, acting through the Administrator of the Federal Highway Administration (referred to in this subsection as the “Secretary”), shall develop a quality standardized methodology for collecting and reporting spatially accurate wildlife collision and carcass data for the National Highway System, considering the practicability of the methodology with respect to technology and cost.
Methodology.— In developing the standardized methodology under subparagraph (A), the Secretary shall—
survey existing methodologies and sources of data collection, including the Fatality Analysis Reporting System, the General Estimates System of the National Automotive Sampling System, and the Highway Safety Information System; and
to the extent practicable, identify and correct limitations of those existing methodologies and sources of data collection.
Consultation.— In developing the standardized methodology under subparagraph (A), the Secretary shall consult with—
the Secretary of the Interior;
the Secretary of Agriculture, acting through the Chief of the Forest Service;
Tribal, State, and local transportation and wildlife authorities;
metropolitan planning organizations (as defined in section 134(b));
members of the Association of Fish and Wildlife Agencies;
experts in the field of wildlife-vehicle collisions;
nongovernmental organizations; and
other interested stakeholders, as appropriate.
develop a template for State implementation of a standardized national wildlife collision and carcass data system for the National Highway System that is based on the standardized methodology developed under paragraph (1); and
encourage the voluntary implementation of the template developed under subparagraph (A).
Reports.—
Methodology.— The Secretary shall submit to Congress a report describing the standardized methodology developed under paragraph (1) not later than the later of—
the date that is 18 months after the date of enactment of the Surface Transportation Reauthorization Act of 2021; and
the date that is 180 days after the date on which the Secretary completes the development of the standardized methodology.
Implementation.— Not later than 4 years after the date of enactment of the Surface Transportation Reauthorization Act of 2021, the Secretary shall submit to Congress a report describing—
the status of the voluntary implementation of the standardized methodology developed under paragraph (1) and the template developed under paragraph (2)(A);
whether the implementation of the standardized methodology developed under paragraph (1) and the template developed under paragraph (2)(A) has impacted efforts by States, units of local government, and other entities—
to reduce the number of wildlife-vehicle collisions; and
to improve habitat connectivity;
the degree of the impact described in clause (ii); and
the recommendations of the Secretary, including recommendations for further study aimed at reducing motorist collisions involving wildlife and improving habitat connectivity for terrestrial and aquatic species on the National Highway System, if any.
establish guidance, to be carried out by States on a voluntary basis, that contains a threshold for determining whether a highway shall be evaluated for potential mitigation measures to reduce wildlife-vehicle collisions and increase habitat connectivity for terrestrial and aquatic species, taking into consideration—
the number of wildlife-vehicle collisions on the highway that pose a human safety risk;
species listed as endangered species or threatened species under the Endangered Species Act of 1973 (16 U.S.C. 1531 et seq.);
species identified by a State as species of greatest conservation need;
species identified in State wildlife plans; and
medium and small terrestrial and aquatic species; and
habitat connectivity values for terrestrial and aquatic species and the barrier effect of the highway on the movements and migrations of those species.
