Prettyboy Reservoir is becoming covered with Japanese Barberry, particularly points of land jutting into the reservoir. I'm shocked that it is still sold, and with no warning, even at respected stores like Valley View Farms.  The Baltimore County parks are rapidly being overtaken by Asian Bittersweet, mile a minute, Japanese stilt grass, wine berry, and multiflora rose and other sticker bushes.  Trees are covered and being pulled down by vines. The ground is either covered by invasives or bare with all native plants eaten by deer. It is distressing watching the trees rapidly being destroyed.

Getting Rid of Japanese Barberry: Why and How

Japanese barberry, (Berberis thunbergi), arrives in the woods by birds eating the fruits in winter and pooping/planting them. It can grow in full shade and established woods. Nobody, (especially not deer), eats the leaves or the prickly twigs. It can root where branches touch the ground and where seeds are dropped in place to make eventually an extensive, dense cluster. Its leaves break down quickly and raise the nitrogen level in the soil, encouraging earthworms and discouraging native woods plants. It offers mice shelter from predators, encouraging them to congregate and share germs. Its dense foliage keeps the area underneath it moist so that ticks can be active almost all the time.

Research by Tom Worthley, ( University of Connecticut Dept of Extension in College of Agriculture & Natural Resource), Scott Williams, ( University of Connecticut Dept of Natural Resources & Environment), and Jeffrey Ward (Connecticut Agriculture Experiment Station Dept of Forestry & Horticulture), found:

o    120 Lyme infected ticks per acre where barberry was “not contained”

o    40 Lyme infected ticks per acre where barberry was “contained”

o    10 Lyme infected ticks per acre where barberry was absent

So that’s why I pull barberry at <http://www.nature.org/photos-and-video/video/fraser-preserve-fairfax-county-virginia>  Fraser Preserve every January & February.

Potowmack chapter removes barberry at Fraser last year. A little snow is helpful, but you can’t pull barberry if the ground is frozen.

I’ve often said that we can work with snow on the ground. Snow actually insulates the ground and keeps it from freezing; it also increases contrast and helps you spot the small barberry sprouts. But we can’t work when the ground is frozen. Last year I had to cancel half the work sessions I’d scheduled because of frozen ground: you just can’t pull plants from frozen ground. The tops just break off and leave the crown of the plant behind, which leaves it alive and harder to pull the next time you try. Other years only one or two scheduled workdays have had to be cancelled: we really don’t get a lot of ground freezing around here, especially not in the woods with a good layer of leaf litter. The barberry at Fraser is not found in bare ground locations where the ground would freeze more readily.

Barberry is what Alan, (Alan Ford, Potowmack Chapter President), calls a “crown plant:” you kill it by removing the junction between the topgrowth and the roots. Often it’s easiest and causes less soil disturbance if you clip the roots and just remove the crown. It does not grow back from bits of root left in the ground. It does grow from seeds dropped under larger plants, so that it is very worthwhile to return to places where there were large plants or patches to pull sprouts until the seed bank is exhausted — I don’t have statistics on this, but most of them are gone after 3 years of sprout-pulling.

Marc, this photo may not meet your needs since it is hard to identify the Japanese Barberry. Just about all of the plants in the foreground are JB as well as the reddish-brown shrubs above the horizontal green area up on the far slope. There were thousands, and possibly tens of thousands of JB plants forming an impenetrable mass except for the trail system. This was the worst site for JB I have ever seen, and I've hiked all over the area.

This photo was on the north side of stream west of Big Falls Road (and east of I-83 I think).

If you need a better photo, maybe the time to go out would be when the plants are in leaf.

Ken

Read  Following is the information we discussed on the value of removing Japanese Barberry and Bush Honeysuckle for control of deer ticks and Lyme Disease .  

I would recommend removing all the Japanese barberry and bush honeysuckle since these invasive plants increase the risk of ticks with the lyme Disease parasite, Borelia burgdorferi, by a factor of 8.8 for the barberry and 10 for the honeysuckle.  When Matt Salo removed all the Japanese barberry at M-NCPPC  Euclid Park in Cheverly all the ticks went away that had been dense.

C. Lyme Disease Management 

There is an 8.8 times increased risk of lyme disease in Jpanese Barberry dominated areas. Jeff Ward reported at the MA-EPPC conference last August 2007 that ticks doubled in Connecticut where Japanese Barberry was present. A year later “The Connecticut researchers found that questing adult ticks were most abundant in areas dominated by Japanese barberry, and that about 44% of the ticks found in barberry were infected with Borrelia burgdorferi, -- the spirochete causative agent of human Lyme disease.  However, only 10% of the less abundant ticks from non-barberry areas were infected. These findings suggest a great probability of humans 

becoming infected with Lyme disease in barberry dominated areas.” 

Thus, there is an 8.8 times greater risk in Japanese barberry patches.

Staff at Catoctin Mountain National Park have been looking for 

justification to control the Japanese Barberry which has evidently 

covered about 1/4th of the 5,000 acres. This may help.

One of the principles of Parasitology is that parasite problems 

increase in disturbed mono-cultural habitats. Shistosomiasis 

from snails in Africa is a classic example with the incidence being 

very low in the more natural areas. We recommend monitoring both 

deer tick density and percent of ticks that are actual hosts of the 

Lyme disease bacteria, Borrelia burgdorferi. 

We have three goals, to reduce lyme disrease, to remove the lyme 

disease barrier to enjoyment of nature, and to provide support for 

control of non-native invasive plants. Note the message below.

NISC Biweekly report for October 17 - October 31 *Meeting

Linkage Between Invasive Plants and Human Disease: October 

2008, 

Scott C. Williams a researcher at the Connecticut Agricultural Experiment Station together with Jeffery S. Ward, Thomas E. Worthley, and Kirby C. Stafford from the University of Connecticut reported that the management of the invasive plant, Japanese barberry (Berberis thumbergii) reduces blacklegged tick (Ixodes scapularis) abundance and could have human health ramifications.  The native white-footed mouse (Peromyscus leucopus) is a primary host for larval and nymphal blacklegged tick. The researchers 

found that tick abundances were greatest in dense barberry.  These ticks are a major vector for agents that cause Lyme disease, human grandulocytic anaplasmosis, and human babesiosis.

For residents of Virginia. 

2)  Wavyleaf Grass:  Budget amendment to provide $200,000 (Senate) and $150,000 (House) to the Department of Forestry to combat Wavyleaf Basketgrass. This plant is a new invasive species with very aggressive characteristics.  It is anticipated to be worse than Japanese stiltgrass (Microstegium) but it currently infests just 300 acres in Virginia, so this amendment provides critical resources to enable eradication of WLBG before it overwhelms natural areas all over the state.

ACTION:

1.       Call or email your Delegate if he or she is a Member of the House Appropriations Subcommittee on Commerce, Agriculture, Natural Resources and Technology:  <http://lis.virginia.gov/cgi-bin/legp604.exe?161+sub+H02003> you can find out here. MESSAGE –“ Please support the Hope amendment, budget item 101 #1h to increase the budget for the Depart. Of Forestry by $150,000 to combat Wavyleaf Grass. This increase is critically needed to eradicate this aggressive invasive non-native plant that could grievously harm the Commonwealth’s natural heritage. This is an invasive plant we can control now before it gets out of hand.” 

1.       Call or email your Senator if he or she is a Member of the Senate Finance Subcommittee on Economic Development and Natural Resources:  <http://lis.virginia.gov/cgi-bin/legp604.exe?161+sub+S05003> you can find out here. MESSAGE: “Please support the Hanger amendment, budget item 101 #2s  to increase the budget for the Dept. of Forestry by $200,000 to combat Wavyleaf Basketgrass.

Hi Everyone -

I hope that everyone across the Commonwealth is cozy and dry as we experience this major snowfall/blizzard. Some important conservation legislation is pending down in Richmond right now. One is a budget amendment to increase funding for the Natural Heritage Program and the two others are bills relating to invasive species. Please click the link and take action as specified. (I apologize to those for whom this is a duplication.)

Thank you!
