County to solicit more feedback on potential deer management strategies next year

Arlington County will kick off the New Year with the next phase of engagement on its forthcoming plan to manage its deer population.

A study found two years ago that Arlington’s deer population exceeds healthy levels, with the county’s forested areas home to about 20 and 39 deer per square. About 1.5 years ago, the Dept. of Parks and Recreation began considering a management plan in response.

Today, the department is considering three ways to lower the population, including sharp-shooting, citizen hunting and sterilization. Another option, fencing off trees, would focus on tackling a purported effect of “overbrowsing,” when large deer populations eat too much of the forest understory.

Some naturalists welcomed the culling options presented. The Animal Welfare League of Arlington, which provides animal control services for the county, meanwhile, champions non-lethal options and has criticized the process so far as “one-sided.”

Early next year, the parks department will host a virtual information session to introduce a second round of community engagement on potential deer management strategies, according to a new timeline it published today (Monday).

Residents can also expect a new feedback form and have the chance to participate in more community meetings before DPR crafts draft recommendations, the timeline says.

These recommendations will be the subject of a third round of public engagement — including another feedback form — before DPR drafts and releases final recommendations.

At some future point yet to be determined, County Manager Mark Schwartz will take action on the final recommendations, per the timeline.

Although this work continues well into 2024, some local environmentalists say the county should have strengthened its discussion of deer management in a forthcoming county master plan governing stewardship of trees and natural resources.

“The role of high white-tailed deer numbers and invasive plants should be more clearly articulated in the environmental degradation of Arlington’s forested areas and included in the plan’s priorities,” Climate Change, Energy and Environment Commission Chair Joan McIntyre wrote in a letter to the Arlington County Board this fall.

“Reducing deer numbers and treating invasive plants are both critical to restoration of our natural areas,” she continued.

The Forestry and Natural Resources Commission expressed its concern that the plan did not treat overbrowsing specifically as a forestry management priority.

“Independent scientific research has ‘noted that tree regeneration failure is widespread and that without active deer management, ecological health of Arlington County’s natural areas will likely continue to degrade,'” writes commission chair Phil Klingelhofer.

The Planning Commission is set to review and vote on the final draft of the Forestry and Natural Resources plan tonight (Monday), teeing up the County Board for a vote on Dec. 16.

The Board authorized this month’s hearings in October. At the time, Board member Takis Karantonis noted he would spend the next two months talking about deer, among other topics.

“There is no question… we are out of balance, we have species that are abundant because we have killed or eliminated factors that balance their population,” he said at the time.

Of deer, the draft plan says “many” Arlingtonians note that expanding deer populations are having “harmful impacts.”

“General sentiment favors striking a balance between managing negative impacts of wildlife while also protecting habitats that benefit Arlington’s ecosystem,” the plan says.

It resolves to inform management with surveys on existing and emerging pests and “high-impact organisms.” By way of example, the plan highlights the 2021 deer count that determined Arlington County had unhealthy deer population levels.

Going forward, “such surveys will be critical to identifying threats early, informing management efforts and can tie into education campaigns,” the plan says.

Animal agency, county commission at odds over deer claims

(Updated at 4:30 p.m.) Two groups have got their antlers locked over whether and how to manage deer in Arlington.

Arlington’s Forestry and Natural Resources Commission, (FNRC) is calling out the Animal Welfare League of Arlington, which handles the county’s animal control service, for “publicizing incorrect and misleading information about deer management,” according to a letter it sent to the county.

After a consultant determined that parts of Arlington County may have deer populations that exceed “healthy” levels, the County Dept. of Parks and Recreation charted out a mitigation strategy. It is mulling four management strategies: sharp-shooting, citizen hunting, sterilizing or building fences. There will be more public engagement and commission hearings before the county makes a decision.

When the initial population numbers were released, AWLA disagreed with the claim that Arlington has “unhealthy” deer levels. Now, AWLA says culling is unwarranted, expensive, ineffective and unsafe.

The FNRC says it supports reducing the deer population to preserve natural resources, including trees, shrubs and wildlife, saying their overgrazing hurts other wildlife and deer themselves. AWLA’s position, it continues, “could cause serious harm to the County’s natural resources.”

“The FNRC is puzzled by the AWLA’s opposition to reducing Arlington’s deer population, because studies also show that lower numbers of deer in the County would result in healthier deer, an outcome that an animal welfare organization should support,” according to the letter from FNRC Chair Phil Klingelhofer.

While AWLA was not able to respond to a request for comment before publication, it laid out its position in a post on its website last month. In a statement to ARLnow after publication, the agency said it stands by its previous statements. It also said it considers the county’s approach to be incomplete and the debate largely one-sided.

“Despite the inherent differences in opinions among stakeholders, we believe it is imperative to consider every side of the discussion to find the most appropriate solution for Arlington,” the agency said in a statement. “A more inclusive process with diverse perspectives will lead to a better-informed decision. It is vital to have more voices at the table, rather than solely those advocating for specific interests, such as tree preservation.”

AWLA suggests sterilization as more humane and effective. Klingelhofer disagrees.

“Indeed, we understand that the Department of Wildlife Resources will not approve of sterilization as a population management tool,” he said. “In contrast, successful culling programs have been implemented in scores of urban and suburban communities across the United States, bringing dramatic improvements in the local environments.”

AWLA also says hunting deer can hurt other wildlife while Klingelhofer says numerous peer-reviewed scientific studies shows the opposite.

The animal control agency says deer are being unfairly blamed for changes to the forest understory also caused by foot traffic and climate change. Klingelhofer emphasizes that deer in Arlington were found to be eating away the understory at substantial rates.

AWLA argues that Arlington has an average of 13 deer per square mile — much lower than neighboring jurisdictions that began culling, such as Fairfax County, with 90-419 deer per square mile, and Howard County, Maryland, with 47-118 deer per square mile. Culling in these counties, it says, has become a permanent but ineffective solution.

Arlington to consider hunting and sterilizing deer, or fencing parks, to cull herds

By Jo DeVoe

Hunting and sterilizing deer and fencing off parks are options Arlington County could pursue to cull its reportedly oversized, and hungry, deer population.

Over the last two years, consultants estimated Arlington has a herd of whitetail deer numbering 290 and, in some areas, the concentration exceeded “healthy” levels.

These large herds are overgrazing the local forest understory and eating away the habitat that sustains birds, insects and bats, according to consultants, the Dept. of Parks and Recreation and some local naturalists.

Now, the parks department is investigating ways to cull the deer. Interested residents can attend a forum on Tuesday, July 11 at the Lubber Run Community Center to learn about management options and share their thoughts.

Through Thursday, July 13, residents can take an online survey to share their thoughts on the four lethal and non-lethal methods on the table:

  • professional sharpshooting
  • surgical sterilization of female deer
  • public archery hunting
  • fenced parks

“We want to be good stewards of Arlington County we’re trying to do the best that we can and this assessment is part of it,” county Natural Resources Manager Alonso Abugattas said in a recent video. “We’re hoping that, through this, we can decide how we can best proceed. This is just the beginning of what promises to be a conversation with the public.”

In the feedback form, Arlington County says sharpshooting, with professionals using sound-suppressed rifles and lead-free bullets, is safe for the public and “the most effective and fastest method for controlling overabundant deer.”

The practice meets euthanasia criteria set by national veterinarian groups. Meat from sharpshooting is donated.

Right behind sharpshooting, in terms of efficacy, could be sterilization. The county says experimental research has shown that, four years after surgical sterilization, deer populations may be reduced to almost half their original size.

Both these would require state permission. Arlington could instead change its own codes to expand archery hunting areas. If it took this course, vetted hunters, using modern compound bows or crossbows, would cull deer.

The county acknowledges the efficacy of archery “is unlikely to be at the level necessary for plant and forest regeneration” on its own and may need to be combined with sharpshooting or sterilization.

Or, Arlington could simply build fences around entire parks — a method that avoids death and sterilization but may be costly and ineffective, the county says.

Fencing “can be expensive to build and maintain, displaces deer into adjacent communities, limits vegetation regrowth to within fence boundaries, and requires vigilance in keeping gates closed and a plan to remove deer should they enter Arlington Parks,” per the form.

Survey respondents are asked how much they support or disagree with the four methods. The county asks which goals it should prioritize in choosing a method, such as forest health, minimized deer suffering and safety.

In the video, Abugattas emphasizes that doing nothing is not an option. An adult deer eats 5-7 pounds of vegetation in a day, or about one ton in a year. After their first year, an adult can produce two fawns every year for up to 20 years.

Naturalists to study deer impacts as Arlington considers population control measures

Has your garden been damaged by hungry deer?

Local master gardeners with the Virginia Cooperative Extension Master Gardeners of Arlington and Alexandria City program are asking residents to fill out an anonymous survey about the impact of deer on private property.

“Information gathered will assist Extension Master Gardeners as they interact with the public on landscape management, urban agriculture education and future outreach programs,” per a release, adding that the survey will be open until March 30 and results available in April.

Meanwhile, this evening (Wednesday), the association of master gardeners, the Arlington Regional Master Naturalists (ARMN), and others, are sponsoring a webinar with a professor who will discuss ways to address Arlington’s reported deer overpopulation issue.

“Deer are charismatic native species that belong in our fields and forests,” Cornell University professor Bernd Blossey said in a statement. “Humans have allowed them to become ecological bullies, and if we are serious about our responsibilities to protect all native species, we need to embrace the need to reduce deer impacts through reductions in the local deer herds.”

The groups hosting the survey and webinar are sounding the alarm on the impacts of deer, including the loss of understory foliage, and saying their current efforts — like protecting native plants with deer-proof cages — are not enough.

“Our suburban forests are dominated by a few native species that deer don’t find appetizing, like Spicebush and Pawpaws, and lots of harmful exotic invasive plants that deer won’t eat,” per ARMN’s website. “Early attempts at habitat restoration were frustrated when overabundant deer devoured the large native plantings.”

The study and webinar come about six months after a wildlife consultant began working with the county to determine if Arlington’s natural lands can support the current deer population and whether the county needs to step up management.

Prior to this, the county had its deer population counted by drone and a report summarizing what the drone recorded found parts of Arlington had populations of 20-39 deer per square mile, which it said was “unhealthy.”

But not everyone agrees with this assessment. Arlington County’s animal control group, the Animal Welfare League of Arlington (AWLA), maintains that the issue is not the number but how humans interact with them.

“Many conflicts with deer in our gardens are a result of planting ornamental non-native plants that are irresistible to deer,” Chief of Animal Control Jennifer Toussaint said in a statement to ARLnow.

“Deer will always seek out tasty hostas and tulips first, regardless of the amount of deer present,” she continued. “The best way to mitigate deer eating from your yard is to plant deer-resistant plant species, erect fencing, and utilize repellents. One or a combination of these techniques is an effective and humane way to co-exist with deer.”

Toussaint said AWLA is working with the county throughout the deer study.

Arlington animal control disputes ‘deer problem’ raised in study

By Jo DeVoe

The Animal Welfare League of Arlington is bucking the results of a study suggesting the county has a deer problem.

Arlington County hired a consultant last spring to count the local deer population using drones. The company published a report in September saying that parts of Arlington had populations of 20-39 deer per square mile in certain places, exceeding what’s considered healthy (between 5 and 15 deer per square mile).

In a statement released Monday, AWLA, which oversees animal control for Arlington County, disputed the idea that the local deer population reaches unhealthy levels and urged the county to adopt a “practical, humane, and sustainable deer management plan” that doesn’t place too much focus on the numbers.

“From our extensive work in humane wildlife management, we know from experience that the issue is not the number of deer but rather the conflicts we have with them,” AWLA President & CEO Samuel Wolbert and Chief of Animal Control Jennifer Toussaint said.

The joint statement comes as county staff prepare to incorporate this data into a broader look at what steps Arlington needs to take, if any, to maintain a healthy white-tailed deer population.

Wolbert and Toussaint say there’s “scientific basis” for the claim that 5-15 deer per square mile is healthy, arguing no single count of deer qualifies as over-population.

“The fact is, determining a ‘healthy carrying capacity’ is a political judgement that is not rooted in biology: some communities, and even areas within a community, will be able to sustain different numbers of deer based on multiple factors, like type and quality of food and cover,” they said. “There is no one ‘magic’ number that any community should have. Saying Arlington County, with 13 deer per square mile, has too many deer is a political determination and not based on the environment in which the deer are located.”

AWLA leaders say complaints about deer may have precipitated this survey, but of all the calls and online reports their animal control division receives related to wildlife, relatively few involve deer.

Since November 2020, when it launched an online reporting system, AWLA has received over 650 wildlife concerns, and of those, 17 (3%) related to deer. Meanwhile, in 2021, 131 calls of the 2,733 calls for service related to wildlife (or 5%) were deer-related — and the most common concern was about the health of orphaned fawns.

“If there truly were ‘too many deer’ we, as the County’s wildlife experts, would have more deer-related complaints or issues arising from deer — which is simply not the case,” Wolbert and Toussaint said.

As for the argument that deer contribute to the destruction of the forest understory, cited in the report, AWLA leaders argue that deers are unfairly blamed for the impacts of other factors.

“It’s easy to blame deer for any forestry growth woes, when the reality is that forests are affected by many factors: insect damage, disease, pollutants (like harsh fertilizers), invasive species, increased foot traffic, climate and weather extremes, over-development… and deer,” Wolbert and Toussaint write.

In response, Arlington County Department of Parks and Recreation said the survey was just the first step in determining whether Arlington needs to more actively manage deer. Next, the county will hire a professional wildlife consultant to interpret this data and gather additional information to determine if and how deer are impacting the natural landscape, said DPR spokeswoman Susan Kalish.

All this information will guide a public engagement process that will culminate with a presentation to the County Board this summer.

“Deer are necessary aspects of wildlife with important ecological functions when in balance with the surrounding habitat,” Kalish said. “Arlington takes its role as a steward of wildlife and its natural lands seriously.”

Arlington deer population exceeds ‘healthy’ levels, study finds

By Jo DeVoe
1/3

Oh deer: Arlington officially has a white-tailed problem.

A study has found that some parts of Arlington have deer populations three to five times greater than what’s considered healthy.

Earlier this year, drones equipped with infrared technology — and permission from federal agencies — flew over Arlington to count the number of deer in the county. The result represents the first ever accurate measure of Arlington’s deer population, according to the county.

From April 8-12, drones registered and the independent firm Steward Green confirmed the presence of 290 deer in Arlington, according to the report. The firm recommends more “management” where populations are the highest and greater monitoring everywhere else.

Following the report’s release in the fall, the county intends to hire a consultant this winter who will determine what that management strategy should be.

While white-tailed deer can contribute to a region’s natural habitat, elevated populations impede the growth of young trees and hurt local flora and fauna, according to the report. They also pose problems for humans, such as vehicle collisions, which have trended down in Arlington since 2020 but are still common in Virginia.

“High deer densities… can lead to intolerable levels of damage to native ecosystems, crops, commercial and residential landscaping, as well as increased safety concerns from deer-vehicle collisions and tick-borne illnesses,” said the report, released this fall.

Deer populations countywide exceed what the land can support, the report says.

“All the areas surveyed in this study have a deer density that is likely beyond the threshold of carrying capacity, have intensified invasive flora, have depleted habitat for (tick eating) ground nesting birds (oven birds, etc.)… and have possible starvation/disease for the deer,” the report said.

Wildlife biologists, ecologists and environmental professionals consider five to 15 deer per square mile to be “healthy,” according to the report. The consultants recommend suburban areas aim for 10 deer per square mile. Arlington has a total of 26 square miles, including both urban and wooded areas.

North Arlington, neighborhoods along the western edge of the county and neighborhoods southwest of Arlington National Cemetery had the highest deer populations, according to the study.

In the following sections, which correspond with the map below, densities ranged between 20 and 39 deer per square mile.

Section G, which includes Army Navy Country Club and is bounded by Arlington National Cemetery, Arlington Blvd and I-395, had 20 deer per square mile.

Section D, which includes the neighborhoods near Bluemont Park and Upton Hill Regional Park and is bounded by the western county edge, I-66 and Arlington Blvd, had 28 deer per square mile.

Section A, which includes the neighborhoods of North Arlington near Marymount University, Potomac Overlook Regional Park and Donaldson Run and is bounded by Langston Blvd and Old Dominion Drive, had 33 deer per square mile.

Section F, which includes neighborhoods north of Columbia Pike near the county’s western border, had 39 deer per square mile.

The consultant says the 290 figure is likely conservative because of the “challenges of daytime collection,” and recommended future counts obtain clearance to fly at night. The drone had to dodge low-flying helicopters and airplanes and had unclear readings due to the presence of competing heat sources.

Watch Out on the Roads: Deer Are on the Prowl

By ARLnow.com

It’s that time of the year.

Deer are answering mother nature’s siren call and venturing out in search of a mate, which can have disastrous results for both the deer and local drivers.

Since Tuesday, Arlington County police have received at least three calls for injured deer on the side of the road, at least one of which was struck by a vehicle.

Collisions between deer and cars in Arlington are actually somewhat rare — “since January 1, 2018, four collisions reports have been taken for incidents causally-attributed to deer,” ACPD spokeswoman Ashley Savage tells ARLnow — but this time of the fall is when the risk is highest.

Arlington County naturalist Alonso Abugattas said it comes down to normally skittish deer becoming uninhibited as their drive to perpetuate the species heightens.

“We are at the start of the rut for deer. This means bucks are chasing does all over the place in order to mate,” Abugattas said. “As this is the one thing they have in their minds, they often ignore cars and this is when the most car deer collisions happen.”

Jennifer Toussaint, the Chief of Animal Control for the Animal Welfare League of Arlington, said in an email that there’s a higher risk of deer-related crashes along roads that abut wooded areas.

“Rutting season for deer is the period of time in the year when they mate. During this time their activity and movement increases and as a result, we see an increase in roadway crossings for deer,” Toussaint wrote. “We see most of the small number of motor vehicle deer collisions that occur yearly during this time.”

“Here in Arlington County those incidents are most likely to occur on the highways and roadways that abut or run alongside our large or conjoining green spaces; such as Arlington Boulevard near Lubber Run, Military Road, GW Parkway, and Spout Run Parkway,” she continued. “It’s important for drivers to be extra vigilant from the second week of October through the first week of December — when their movement activity is at its peak.”

Toussaint offered the following safety tips for drivers.

Ways to Increase Safety During This Time:

  • Be vigilant, especially at dawn and dusk when deer activity is at its highest. Watch from side to side as you drive, especially in areas of low visibility or where shrubs or grasses are near the road.
  • Watch for group behavior. Deer often travel in groups. If one deer crosses the road, slow down and watch for more to follow. Females travel together in winter, and fawns follow their mothers in spring and summer. Male deer travel alone during rutting season.
  • Use your high beams at night when possible and turn down interior lights and put away distractions (such as cell phones) to see farther ahead. Slow down and watch for the eye-shine of deer near road edges.
  • Use your high beams at night when possible and turn down interior lights and put away distractions (such as cell phones) to see farther ahead. Slow down and watch for the eye-shine of deer near road edges.

She also noted that instances of injured deer have been decreasing, particularly during the pandemic, despite the sudden spike this week.

“Overall deer intake to animal control actually went down an additional 38% in 2020,” Toussaint wrote. “To date this year in 2021, we are down an additional 18% on intake to the even low intake of last year. Arlington County Animal Control works with Arlington County’s DES team to ensure that if there are any collisions in certain areas that warning signs are put up for motor vehicle drivers. Our overall calls regarding deer concerns has also steadily decreased yearly over the past 4 years as well.”

Arlington County to Use Drones to Count Deer

By ARLnow.com

A fleet of drones will take to the skies above Arlington next month in an effort to figure out how many deer call the county home.

The drones will be piloted by a firm contracted by the county and overseen by Arlington County police. Normally, drone flights this close to D.C. are strictly prohibited, but Arlington is being granted special permission by the Federal Aviation Administration and other federal agencies. The county is also coordinating with Reagan National Airport.

The drones will look for heat signatures in the woods in order to develop a count of Arlington’s white-tailed deer. This will be “the first accurate measure of Arlington’s deer population,” the county says, noting that “only anecdotal data… currently exists.”

The dones will be launched just before sunrise on Monday, April 5 and the count will continue until just after sunset, for up to two weeks.

The county is careful to note that the drones will only be looking for deer and will “not identify people.”

More from a county press release, below.

Arlington County has hired a contractor to perform a drone survey of heat signatures of the County’s white-tailed deer population. The survey information will assist with the development of the County’s Forestry and Natural Resources Plan. The survey will only collect heat signatures of deer and does not identify people.

“We’ve all seen deer in the County at one time or another,” said Alonso Abugattas, the County’s Natural Resource Manager. “We’d like more than just anecdotal evidence. We want to clearly see how many and where they are so we can mindfully steward our natural resources.”

Thermal and infrared imagery has helped improve counting by relating animals’ unique heat and visibility signatures to precisely count only deer. In one study, it was shown that Unmanned Aerial Vehicles (UAVs), commonly referred to as drones, can be about 43-96% more accurate than ground or human-made observations in counting wildlife. Montgomery County, MD, has conducted UAV deer surveys in locations throughout Montgomery to determine carrying capacity.

The drones will be flying over Arlington beginning a half hour before sunrise April 5 (weather permitting) each day until 30 minutes after sunset, until the survey is completed. They will not be flying at night. The survey could take up to two weeks but is weather dependent. Drones are not permitted to fly over Arlington except for very limited instances. Arlington has coordinated the project with US Department of Homeland Security, Federal Aviation Association (FAA), Transportation Security Administration, Ronald Reagan National Airport, and Arlington County Police Department (ACPD). In accordance with FAA guidelines, ACPD will be onsite monitoring the drone flights.

This will be the first accurate measure of Arlington’s deer population. Only anecdotal data on Arlington currently exists. By 1900, white-tailed deer population had been destroyed in most of Virginia. Through the 1940’s to 1980’s with restocking efforts, laws protecting deer and favorable habitat, deer have rebounded at an exponential rate in Virginia.

Accurate data will determine Arlington’s deer carrying capacity. Deer are important and a necessary aspect of wildlife with important wildlife functions when in balance with the surrounding habitat. Per the Virginia Department of Wildlife Resources, the carrying capacity for deer can vary widely between and within communities. Data from the surveys will help determine Arlington’s carrying capacity.

Video: Spotted Deer Going Buck Wild on Williamsburg Blvd

By ARLnow.com

An especially bold deer with unique markings was seen going for a morning run in Arlington’s Williamsburg neighborhood today.

A reader sent the above video, taken at the intersection of Williamsburg Blvd and N. Ohio Street, wondering what the heck is going on with the “cow deer” that was galavanting around the neighborhood.

We steered that question to Alonso Abugattas, Arlington’s Natural Resources Manager — the expert in all things wildlife in the county.

“This is a piebald buck,” Abugattas explained. “As it’s the rut season, this buck is looking for does in estrus, and so is taking a lot of chances he would not normally do, often resulting in this being when the most road kills happen and car accidents involving deer happen.”

In other words, the deer has a recessive genetic trait that causes the cow-like spots, and was literally going buck wild looking for a mate.

That may answer the videographer’s question, but the takeaway for drivers is to remain alert on the roads this time of year, even in Arlington. You never know when a hyped-up deer will cross your path.
