Reporting ‘Rhode Kill:’ New study calls on citizen scientists
DEM issues new rules to allow you to eat what you find

According to the U.S. Department of Transportation, there are more than one million wildlife vehicle collisions in the United States annually with significant personal and economic costs: they result in approximately 200 deaths and 26,000 injuries to drivers and passengers and cost more than $8 billion annually.Rhode Islanders can now report roadkill that they hit or
observe using a QR-code generated survey, also
available online. The public’s participation will ultimately inform
research efforts to mitigate risks for both drivers and animals.
“If we identify key hotspots for roadkill, we can advise the Rhode Island Department of Transportation on ways to increase successful wildlife crossings,” Carroll says. Usage of the survey is anonymous. With permission, it will pull the respondent’s GPS location but no personal data.
The pervasive problem of roadkill illuminates larger concerns about wildlife connectivity, the ability for animals to move freely from place to place. In western states, known migration pathways have informed efforts to facilitate safe movement through large underpasses and overpasses. We have eight of the ten most densely populated states in the northeast, Carroll notes, and the abundance of roadways and cities creates certain concerns.
“Here we have animals moving around, but we don’t have massive ungulate
or mammal migrations, so we don’t have giant wildlife bridges or other things
that work out west,” Carroll says. “There have been a lot of discussions about
what is important when we start thinking about connectivity in New England
specifically.”
Data from the survey will complement research conducted by Carroll’s graduate students that uses camera trap data to record animals’ usage of culverts. “We know that animals are willing to use culverts, as opposed to crossing on the road, because they don’t want to be somewhere they’re going to die,” Carroll says.
“So what is it about some culverts that makes them willing
to use it as opposed to others?” Identifying what’s happening spatially at
culvert sites provides crucial information on predicting animal behavior before
fatal road crossings.
The data from the Rhode Kill Survey will be paired with
traditional data collection methods: graduate students in Carroll’s Quest Lab will
complete surveys that utilize standardized effort, driving the same amount of
distance from randomly assigned starting points and then pulling off the road
to pick up roadkill for assessment of species, age, sex, and other
identifications.
“It will ensure the patterns we’re seeing in the citizen
science data match the pattern in the data we’re collecting,” Carroll says.
The Rhode Island Department of Environmental Management and
the popular GPS app Waze currently collect roadkill data, but it’s very
disparate. Carroll and the team are interested in establishing a data-sharing
agreement to ensure all collected data can be used more effectively to mitigate
risks.
While the survey is in its early days, there is already
growing interest in the work, including from the New York Department of
Transportation.
“We’re starting with Rhode Island to pilot it,” Carroll
says, “but the goal is to expand it to other regions.” Establishing a
standardized protocol that all states follow will allow data to be integrated
for a larger analysis. Carroll notes that the research team might also add more
questions over time to expand the information captured with the hopes of being
more broadly beneficial to a variety of research goals.
The only required question on the Rhode Kill Survey is
whether or not the animal was a deer. Additional optional questions include the
ability to upload a photo and to participate in a follow-up driving survey. The
latter is particularly useful to researchers, Carroll notes, because it
provides information about the level of effort and driving habits of
respondents.
“In the field of ecology, we’ve demonstrated that
historically, citizen science data is essential for large-scale projects,”
Carroll adds. The survey will remain open for the foreseeable future.

Permit Allows Public to Salvage Roadkill
The Rhode Island Department of Environmental Management (DEM) is announcing a new regulation that allows the public to collect certain wildlife species killed in vehicle collisions.
Recently passed legislation sponsored by Chairman of the House Environment and Natural Resources Committee David Bennett and Senate Majority Whip David Tikoian gives DEM more flexibility to address wildlife vehicle collisions, enabling the public to salvage deer or other wildlife with a permit.
This approach makes use of an underutilized resource and eases the burden on state staff removing carcasses. A permit is required within 24-hours of collecting wildlife struck by a vehicle. To receive a permit, the public must report the species, estimated age and sex, a photo, and location. Eligible species include white tailed deer, turkeys, beavers, coyotes, fishers, red and gray foxes, muskrats, pheasants, squirrels, rabbits, and racoons.
Fisher and foxes have additional
requirements found in the regulations on the reporting webpage. Reports can be
submitted via the form at www.dem.ri.gov/wildlife-salvage-permit or
by leaving a message at 401-789-0281 with the required information.
Before salvaging roadkill, the public should prioritize
safety and follow traffic laws. The animal may be field dressed before it’s
removed, but parts cannot be left behind, which is a violation of state law and
risks attracting other wildlife. The permit allows the possession of one animal
killed only by vehicular collision – each individual animal requires its own
unique permit.
The new legislation expands reporting requirements to
include most wildlife collisions that cause significant vehicle damage, not
just deer. This ensures that all vehicle collisions involving wildlife are
reported to DEM. Reporting helps DEM’s Division of
Fish & Wildlife (DFW) track populations and improve highway
safety. Road-killed animals may not be tagged with hunting tags, and injured
animals cannot be killed for salvage, though law enforcement may euthanize and
allow salvage.
Last year, DEM received 1,347 reports of deer vehicle
collisions (DVCs). DVCs are a public safety risk and average $6,717
in damages per collision according to the Federal
Highway Administration. Deer reproductive behavior drives most DVCs. White-tailed
deer are common in Rhode Island and regulated hunting is the most effective, method of
controlling deer populations, balancing ecological and social factors. DEM
biologists seek to balance hunting opportunities while reducing the negative
impacts of overpopulated deer, including crop losses, nuisance complaints, and
DVCs.
