The 18 people on the regular monthly walk at the Blue Ridge Center in the northwestern park of Loudoun County managed to tally 41 species on Saturday. The highlights of the walk on the Farmstead Loop were two very vocal Broad-winged Hawks who were also seen in the heavy forest along Piney Run. Also of interest were what appeared to be several family units including a fledgling crow begging for food and several orioles and very low warbler diversity. And like many high-summer walks some of the most int’g sightings were not birds; in today’s case it was a live & healthy Luna Moth, a Monarch Butterfly laying eggs, and several other butterflies.

Also, don’t forget that next Saturday is Loudoun Wildlife’s annual butterfly count and the Blue Ridge Center is one of several locations that will be visited that day in the county. Beginners and experienced butterfliers are welcome for all or part of the day.

For a complete list of the birds see the eBird list below.

Loudoun-flooding-aerialThe Loudoun County Planning Commission is reviewing a proposal to weaken protections for floodplains, the buffers before our streams which protect our water from pollution and help protect us from flooding.

 

Loudoun Wildlife Conservancy has written the following letter to the Planning Commission.   Please join us in speaking up for floodplain protections!  You can email the Planning Commission, or speak at their public hearing scheduled for Tuesday July 21, 6 pm at the Loudoun County Government Center.  (Email contact information in the letter below, and at http://www.loudoun.gov/pc.  Public meeting information at http://loudoun.gov/Calendar.aspx.)

 

Loudoun Wildlife Conservancy also plans to join the Loudoun County Preservation and Conservation Coalition in speaking up for floodplain protections to the Board of Supervisors – especially in preparation for the Supervisors’ scheduled October 14, 2015 public hearing on this issue.

 

Additional details about the proposal can be found on the Loudoun Preservation and Conservation Coalition website, and also in county documentation prepared for the July 21 Planning Commission meeting.

Please Reject Proposals to Weaken Floodplain Rules

Dear Planning Commission Members:

I write to you on behalf of the 1,000-member Loudoun Wildlife Conservancy, to ask that you say ‘NO’ to proposed zoning rule changes whose purposes include:

  • Allowing more uses in floodplains, such as new storm water management facilities, parking areas, outdoor storage, and swimming pools.
  • Relocating natural stream channels.
  • Allowing specific changes through the Minor Special Exception process, which would reduce opportunities for citizen input.

County professional staff have identified numerous ways in which the proposed zoning rule changes could introduce contaminants into our water supply, and increase flash flood threats to life and property.

Throughout our 20-year history, Loudoun Wildlife Conservancy has stressed the important role of floodplains in mitigating downstream flooding, protecting surface water quality, and providing critical wildlife habitat.  We have emphasized that the cumulative effect of floodplain construction increases the volume and velocity of flood flows, and the rate of stream bank erosion.

We ask that you promote Loudoun County citizens’ health and safety, and our environmental quality, by rejecting proposed floodplain rule changes that are apparently designed to benefit a small number of individuals at the expense of the larger community.

Thank you very much for your time and consideration.

Sincerely,

Alysoun Mahoney

15-DSC_0130The Loudoun County Board of Supervisors is in process of reviewing proposals that would threaten steep slopes and floodplains.  Protections for these critical natural resources have been in place for many years under the Revised General Plan that was adopted by the Loudoun County Board of Supervisors with extensive citizen involvement.

 

The first proposal, which would open up fragile steep slope land for new uses, will be put to a vote of the Board of Supervisors Transportation and Land Use Committee in their Friday, July 17, 9 am meeting.

 

Additional details about the proposal can be found in documentation prepared for this meeting at loudoun.gov, and also on the website of the Loudoun County Preservation and Conservation Coalition of which Loudoun Wildlife Conservancy is a member.

 

Loudoun Wildlife Conservancy has written the following letter to the Board of Supervisors, and we urge our members and friends to share their views with their elected County representatives as well.

Geary.Higgins@loudoun.gov, Scott.York@loudoun.gov

 

Dear Board of Supervisors Transportation and Land Use Committee Members – Supervisor Volpe (Committee Chair), Supervisor Clarke, Supervisor Delgaudio, Supervisor Higgins, and Supervisor York:

 

I write to you on behalf of the 1,000-member Loudoun Wildlife Conservancy, to ask that you reject proposed zoning changes in ZOAM 2014-0004 whose purpose is to allow more uses in steep slope areas.

 

First, the proposed changes would violate the Revised General Plan that was adopted by the Loudoun County Board of Supervisors with extensive citizen involvement, which states in Chapter 5 that the County will “prohibit land disturbance on slopes with a grade of more than 25 percent,” and that “special performance standards are to be used to protect slopes with grades from 15 to 25 percent.”

 

Second, the proposed changes threaten Loudoun County’s environment. As stated in the Revised General Plan, “steep slopes protected as part of a river and stream corridor or mountainside often serve as forested and vegetative areas that filter stormwater run-off and support various plant and wildlife habitats….Development on steep slopes often requires high volumes of clearing and ‘cut and fill.’ Such earth moving is subject to erosion and sedimentation that causes adverse effects on surface water quality and aquatic habitat.”

 

Third, we are concerned that the proposed changes would benefit a small number of individuals – for example, those seeking to build hillside residences – at the risk of general public health and safety. As stated in the Revised General Plan, “if improperly used and disturbance occurs, these areas could experience erosion, building and/or road failure, downstream flooding, and other hazards.”

 

Fourth, we have reason to believe that although the goal of the proposed changes is to be more ‘business friendly’, in fact the reverse will occur:  new development on steep slopes would have adverse impact on Loudoun County’s rural economy and tourism.

 

Finally, the proposal includes allowing changes to development standards through the Minor Special Exception process, which would reduce opportunities for citizen input.

 

Please work to keep Loudoun County beautiful, and to keep all our citizens safe and prosperous, by rejecting zoning changes that would allow more uses in steep slope areas.

 

Thank you very much for your time and consideration.

 

Sincerely,

bluebirds Efforts are underway in the U.S. Congress to prevent the enforcement of the Migratory Bird Treaty Act (MBTA).

 

The American Bird Conservancy (ABC) advises that “the Senate may soon consider a rider in the Fiscal Year 2016 Commerce, Justice, Science, and Related Agencies (CJS) appropriations bill to bar the Department of Justice from enforcing the MBTA, which protects over 1,000 species of migratory birds.”

 

Furthermore, in the House, Rep. Jeff Duncan is trying to add to the Interior Appropriation Bill an amendment that would prevent the enforcement of laws protecting Bald and Golden Eagles, as well as the laws protecting migratory birds.

 

SEO_Liam_McGranaghan2a-150x150Loudoun Wildlife Conservancy is joining ABC and conservation organizations across the nation in cosigning a letter to the Chairman and Ranking Member of the Senate Appropriations Committee, asking that they maintain all existing protections for migratory birds.

 

Loudoun Wildlife Conservancy also invites individual members to send the same request to Virginia’s U.S. Senators.  You can easily do this by going to support.abcbirds.org/ProtectMBTA and personalizing and sending a letter prepared by ABC.  Alternatively, you can deliver your message directly by calling or writing the offices of Senator Mark Warner and Senator Tim Kaine.  Contact information can be found at http://www.senate.gov/general/contact_information/senators_cfm.cfm?State=VA.

 

As always, thank you for your efforts to protect Loudoun’s wildlife.

LymePrevention-LongPants

Loudoun Wildlife Conservancy Habitat Restoration Chair Moni Burke, a Cascades resident, submitted a Lyme prevention article by invitation this month for her community association newsletter.  We are pleased to share the full text here, and we welcome our members and friends to share it with their communities.  (Photo by Jared Garland.)

 

 

Lyme Prevention: Highest-Efficacy, Lowest-Cost, and Lowest-Toxicity Methods

Many of the methods for Lyme disease prevention which studies indicate to be most effective are low- or no cost, and carry low or no risk. The highest-efficacy, lowest-cost, lowest-toxicity Lyme prevention methods are tick checks and protective clothing. These personal measures and other effective landscape management methods for the homeowner are outlined below.

 

1. Personal Protective Measures

A. Tick checks and prompt removal

The definitive Tick Management Handbook states that “checking for ticks and prompt removal of attached ticks is probably the most important and effective method of preventing infection!” – and indeed, most scientific studies have supported this assertion.

 

B. Protective Clothing

The Tick Management Handbook recommends wearing long pants tucked into socks to make ticks easier to detect and keep them on the outside of the clothes. A 2008 Center for Disease Control (CDC) Connecticut study of nearly 2,000 individuals found protective clothing – defined as long pants and long-sleeved shirts to be 40% effective in preventing Lyme disease. Wearing this type of protective clothing is a risk-free prevention method.

 

2. Landscape Management

A. Tick-safe zones

According to a study referenced in the Tick Management Handbook, the nymphal blacklegged tick whose bite is the primary cause of Lyme disease in humans, is found mainly in densely wooded areas (67%) and in transitional edge ecotone habitat between woodlands and open areas (22%), which provide the relatively high humidity necessary for their survival. Fewer ticks are found in ornamental vegetation (9%) and lawn (2%).

 

The Tick Management Handbook, CDC and other sources recommend that families create tick-safe zones in lawns and play areas around their homes – isolating these zones from tick habitat with a wood chip or gravel barrier of approximately 3 feet, and then increasing exposure to sun and air in those zones. The Tick Management Handbook notes that acceptable alternatives to lawn include butterfly gardens, vegetable gardens, formal herb gardens, colonial style gardens, wildflower meadows and hardscapes.

 

These measures have been shown to reduce tick numbers on the subject property. However, a recent study showed them not to be significantly protective against Lyme disease – and the Tick Management Handbook concludes that “landscape management alone may not reduce disease incidence, as the undetected bite of only one infected tick is required for transmission of Borrelia burgdorferi.” Borrelia burgdorferi is the bacteria causing Lyme disease.

 

There is no real risk associated with this type of landscape management. The cost will vary depending on lot size and existing landscaping.

 

B. Replacing exotic invasives with native plants

Multiple studies have shown that controlling invasive plants, especially Japanese barberry, helps to reduce both total tick numbers and infected tick numbers. Two Maine Medical Center Research Institute studies, and the Tick Management Handbook, indicate that blacklegged ticks are significantly more abundant in areas dominated by exotic invasive plants, particularly Japanese barberry, than areas dominated by native shrubs. A 2010 Connecticut study indicates that control of Japanese barberry – either through cutting off the above-ground portion or using a flame treatment – “reduced the number of ticks infected with Borrelia burgdorferi by nearly 60% by reverting microclimatic conditions to those more typical of native northeastern forests.”

 

Invasive removal alone may in some cases be sufficient for native plants to return to the area without further effort or expense by the homeowner – though in some cases, there may be cost and labor associated with acquiring and planting new native shrubs.

 

Invasive plant removal carries no risk except for that associated with use of standard garden tools, and it carries many environmental benefits.

 

C. Promotion of vertebrate biodiversity

Recent research on Lyme disease mitigation points to a whole new paradigm, suggesting that we should focus not on culling or excluding one or two specific tick-carrying mammal species (such as deer or mice), but rather on fostering life for many diverse species of fish, amphibians, reptiles, birds, and mammals.

 

At the homeowner or property manager level, one way to promote vertebrate diversity is by replacing exotic invasive plants with native plants, as discussed in section 2B above, and by restoring habitat diversity, health, and complexity. As entomologist Douglas W. Tallamy writes, “because animals directly or indirectly depend on plants for their food, the diversity of animals in a particular habitat is very closely linked to the diversity of the plants in that habitat.”

 

Some research shows that at the community planning level, a key way to promote vertebrate diversity and thereby reduce Lyme disease risk is to discourage land-use practices that fragment our forests. This is because forest fragmentation tends to favor a small number of mammal species that are relatively likely to infect ticks with Lyme disease bacterium, while reducing populations of other species that are unlikely to be infected with Lyme disease bacterium.

 

Note on chemical spraying for ticks

The pesticides primarily used for tick spraying are bifenthrin and permethrin, both of which are a pyrethroid that is currently classified by the EPA as a Group C carcinogen (possible human carcinogen – cancer causing) and highly toxic to bees, fish, and aquatic invertebrates.

A nature walk on the Morven trail.

A nature walk on the Morven trail.

More than 150 members, family, and friends joined in the celebration of Loudoun Wildlife’s 20th year at the Annual Meeting Sunday, May 31, at Morven Park. Predicted showers held off a day, allowing hikers to explore Morven on a nature walk and gardeners to acquire a few more native perennials for their pollinator-friendly plantings, as musicians filled the sultry air with good tunes.

The crowd moved into the coolness of the Carriage Museum for refreshments and the meeting, at which the membership voted to approve the slate of Loudoun Wildlife board members serving another 2-year term (Joe Coleman, Jim McWalters, Sarah Steadman) and new board members (Bill Brown, Hatsy Cutshall, Jill Miller, and Phil Paschall). Outgoing President Joe Coleman thanked outgoing board members Janet Locklear (who also received the Volunteer of the Year Award), Phil Daley (who has been on the board for 19 years), and retiring Secretary Rhonda Chocha for their service.

Thirty-five birders showed up for the regularly scheduled monthly bird walk at the 900-acre Blue Ridge Center for Environmental Stewardship in northwestern Loudoun County this past Saturday morning. This month’s walk was sponsored by both the Loudoun Wildlife Conservancy and the Northern Virginia Bird Club and split into two different groups. One group, led by Elton Morel & Marc Ribaudo, concentrated on the area around the Education Center & organic farm and found 59 species; the other group, led by Joe Coleman & Mary Ann Good, walked the trails at the southern end of the property and found 57 species. Neither group spent much time in the forest and, for the most part, found the same species with some notable exceptions such as the four Chats found around the Education Center. After the scheduled walk a couple people briefly visited the open areas under the power line on Arnold Road and added American Robins and two counter-singing Orchard Orioles to the days list.

The highlights of the 70 species were five Blue-winged Warblers, a couple of which were well-seen, a flyover Broad-winged Hawk, one Cerulean Warbler, and 4 Yellow-breasted Chats.
