Because this information is so important to our community I felt it best not to wait. Please take a moment to find out how you can help protect our seacoast.

Emerald Ash Borer Moves Closer to the Seacoast<br />
<br />
Emerald Ash Borer (EAB), the invasive beetle that is killing ash trees in the US at an alarming rate, has been detected in North Andover, MA. That’s just 3 miles from the NH border, and 30 miles from Portsmouth. As a result, Essex County, MA has placed a quarantine on the transportation of firewood and untreated lumber. EAB was detected in Concord, NH in 2013 and a similar quarantine is in effect for Merrimack County. If we want to save our ash trees, it’s time to start treating ash trees on the Seacoast.<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEglX4DAz_nfE01asyySXr0KR93NqfAUq20NcHgUKMRsWrWYUkjFyiHsSKswYVu5vtv_3emKJdMWB-JqACV6xdhwX46hQetFsvPdLmWm7vKMU1yuzv336aZEVQ7HEekhLNfY7IafG1YqAjI/s1600/shutterstock_39442303.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img alt="Emerald Ash Borer" border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEglX4DAz_nfE01asyySXr0KR93NqfAUq20NcHgUKMRsWrWYUkjFyiHsSKswYVu5vtv_3emKJdMWB-JqACV6xdhwX46hQetFsvPdLmWm7vKMU1yuzv336aZEVQ7HEekhLNfY7IafG1YqAjI/s1600/shutterstock_39442303.jpg" height="320" title="" width="206" /></a></div>
<br />
The discovery of EAB in North Andover was lucky, and it shows how we can all help keep an eye out for the spread of this pest. Matthew Mountzuris noticed a stand of trees with dead canopies and increased woodpecker activity and called the Department of Conservation and Recreation in Massachusetts. Turns out they were all white ash, and all infected.<br />
<br />
Here’s what you can do:<br />
<br />
<b>Burn It Where You Buy It:</b> If you only take one thing away from this article, it should be this: Don’t transport firewood! If you’re going camping, or know anyone who is, tell them not to bring their own firewood but buy it locally at the campsite. Experts agree that the transportation of firewood can move invasive pests hundreds of miles and is one of the biggest threats to our ash trees. (And if you do buy firewood at the campsite don’t bring any back with you.) If you buy firewood to heat your home, ensure it is locally sourced (and preferably kiln dried). <br />
<br />
<b>Identification and Inspection:</b> If you don’t how to identify an ash tree, go to <a href="http://www.nhbugs.org/">www.nhbugs.org</a>. This site is the best resource for current information on EAB in New Hampshire. The site has great information and links on how to identify ash trees and how to inspect your trees for infestation. Learn what signs and symptoms to look for, and inspect your property thoroughly. If you find signs of infestation, you can submit a report at the NH Bugs site. If you see trees this spring that have dead or dying canopies, that’s a great indication of a potential problem.<br />
<br />
<b>Spread the Word (and Keep Yourself Informed):</b> Tell your neighbors and friends who own property with ash trees about the EAB. Stay current on the latest news, treatment options and the spread of the infestation. As the experts learn more about what works and what doesn’t treatments are changing and evolving. The United States Department of Agriculture has a great site at <a href="http://stopthebeetle.info/">http://stopthebeetle.info</a> which has a wealth of information to keep you up to date, as well as some fun projects that will help your kids learn about the EAB, too.<br />
<br />
<b>Treatment:</b> Best treatment options for EAB is surrounded by debate and conjecture, and is best left to professionals who have kept current the latest research. The Seacoast, and the Great Bay in particular, are extremely sensitive areas and misuse of insecticides can kill wildlife and endanger our ecosystem. Initial intensive studies by Michigan State University have shown trunk injection treatments with emamectin benzoate to be up to 99% effective and last as long as 3 years, so there is hope. There are also ongoing studies of non-stinging parasitic wasps that are a natural predator, and these show great promise.<br />
<br />
The Emerald Ash Borer has already killed millions of trees, and the spread has continued every year since it was first discovered in Michigan in 2002. Let’s all make it a priority to protect our region against the spread of the EAB. In turn, we’ll be protecting our forests, our Seacoast, our campsites, our fishing holes, and our neighborhoods.

What on Earth is the Emerald Ash Borer and why should I care? This really is two separate questions, so I'll take them one at a time. <br />
<br />
<b>About the EAB:</b> The emerald ash borer was discovered in southeast Michigan
in 2002. Some estimates put the the number of ash trees killed as high
as 100 million. It's a green beetle native to Asia - big deal right? But it's also an invasive beetle that attacks and kills ash trees. Voraciously.<br />
<br />
This little bugger has been spotted in Concord NH and an emergency quarantine has been put in place in Merrimack County banning all species of ash (including wood chips, firewood and the like) from traveling outside the county limits.<br />
<br />
Currently, 2 meetings are scheduled for May 2, and include the New Hampshire Department of
Agriculture, Markets & Food, the New Hampshire Department of
Resources and Economic Development’s Division of Forests and Lands, the
U.S. Department of Agriculture, Animal and Plant Health Inspection
Service Plant Protection and Quarantine (USDA APHIS PPQ), the U.S.
Forest Service, and yours truly, Dan Mello. The state and the country are taking the spread of this pest very seriously and so are we. We are attending to learn as much as we can, not only to take a proactive approach, but to help keep the community informed in order to solicit their help, if and when it becomes necessary.<br />
<br />
<b>Why Should I Care? </b>It may seem that the loss of ash trees may not affect you, especially if you don't have any on your property. But this invasion affects everyone: The excerpt below was taken from a recent study by the US Forest Service <a href="http://www.fs.fed.us/pnw/news/2013/01/tree-human-health.shtml">http://www.fs.fed.us/pnw/news/2013/01/tree-human-health.shtml</a>.<br />
<i>In an analysis of 18
years of data from 1,296 counties in 15 states, researchers found
that Americans living in areas infested by the
emerald ash borer, a beetle that kills ash trees, suffered from an
additional 15,000 deaths from cardiovascular disease and 6,000 more
deaths from lower respiratory disease when compared to uninfected
areas. When emerald ash borer comes into a community, city streets
lined with ash trees become treeless.</i><br />

<span id="internal-source-marker_0.1982701059974683" style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">Now
that winter is waning and spring is upon us, we begin to think about
our annual spring cleanup. The days are getting longer and warmer and
we are spending more time outside. It becomes easier to see the tree damage winter
brings. Before you go grabbing Dad’s old chainsaw for some <a href="http://www.seacoasttreecare.com/tree-care.cfm" target="_blank">tree service</a>, take a
moment and read the following tips.</span><br />
<ul style="margin-bottom: 0pt; margin-top: 0pt;">
<li dir="ltr" style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; list-style-type: disc; text-decoration: none; vertical-align: baseline;"><span style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">First things first: If you find any downed power lines, steer clear and notify the
power company immediately! (I know everyone knows this, it’s like the
scissor running thing, but I felt compelled to say it anyway...).</span></li>
<li dir="ltr" style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; list-style-type: disc; text-decoration: none; vertical-align: baseline;"><span style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">Do
not use a chainsaw simply because you have one. Although they are
extremely useful tools, they are also extremely dangerous. If you
haven’t been trained, or are not familiar with it, ask someone
for help (there is no shame in it) or use a handsaw. </span></li>
<li dir="ltr" style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; list-style-type: disc; text-decoration: none; vertical-align: baseline;"><span style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">If your going to remove a tree or large limb, be sure there are no power lines, property, or people that may interfere (not including your mother-in-law) with its safe removal.</span></li>
<li dir="ltr" style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; list-style-type: disc; text-decoration: none; vertical-align: baseline;"><span style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">If you have to leave the ground to make the cut, and are not properly trained... STOP! Call a professional.</span></li>
<li dir="ltr" style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; list-style-type: disc; text-decoration: none; vertical-align: baseline;"><span style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">Take the time and assess the situation. Imagine the worst case scenario. What would happen? What would you do? Are you alone? Did you leave yourself an "out"? </span></li>
</ul>
<br />
<span style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">We all want our property to look good (or at least slightly better than our neighbors). Trees are beautiful miracles of nature. They provide us with beauty, protection, and lots of leaves to rake in the fall. If you have any doubts regarding safety, consider hiring a professional. Your family wants you around and so do we. Besides, trees are much more enjoyable from above the soil line... </span><br />

<span class="Apple-style-span" style="font-family: Arial; font-size: 14px;">Don't look now, but the infamous winter moth has officially debuted in Maine. Confirmed in the Cumberland county town of Harpswell last month, the moth now contaminates a 400 acre stretch. Stopping the winter moth outbreak is a <span class="Apple-style-span" style="color: red;">code red mission</span> for scientists, forest services, and you. This moth lays eggs that hatch into binge-eating caterpillars, devouring the leaves of any and all vegetation including oaks, cedars, even blueberry bushes. Have you seen trees with leaves like swiss cheese? Well, that could be the winter moth. A species native to Europe, the moth was found in Nova Scotia in the 1950s, and has since invaded tens of thousands of acres in Massachusetts and New Hampshire. Maine is just the latest of our New England states to be hit.</span><br />

<b><span style="color: red;">It's here.</span></b><br />
More than half of the properties with hemlocks that we look at have adelgid on them. I was recently in the Newburyport, MA area, and a majority of trees I saw had signs of infestation. This is a very destructive pest that can kill trees in 3-6 years. If you have hemlocks on your property please call us. There are a number of different treatment options available some providing 5 years of coverage.<br />
<br />
This is a pest that affects us all, and must be treated before we lose an irreplaceable resource.<br />

Native to Asia, the hemlock woolly adelgid (<em>Adelges
tsugae</em>) is a small, aphidlike insect that threatens the health
and sustainability of eastern hemlock (<em>Tsuga canadensis</em>)
and Carolina hemlock (<em>Tsuga caroliniana</em>) in the Eastern
United States. Hemlock woolly adelgid was fi rst reported in
the Eastern United States in 1951 near Richmond, Virginia.
By 2005, it was established in portions of 16 States from
Maine to Georgia, where infestations covered about half
of the range of hemlock. Areas of extensive tree mortality
and decline are found throughout the infested region, but
the impact has been most severe in some areas of Virginia,
New Jersey, Pennsylvania, and Connecticut.<br />
Hemlock decline and mortality typically occur within 4
to 10 years of infestation in the insect’s northern range,
but can occur in as little as 3 to 6 years in its southern
range. Other hemlock stressors, including drought, poor
site conditions, and insect and disease pests such as
elongate hemlock scale (<em>Fiorinia externa</em>), hemlock looper
(<em>Lambdina fiscellaria fiscellaria</em>), spruce spider mite
(<em>Oligonychus ununguis</em>), hemlock borer (<em>Melanophila
fulvogutta</em>), root rot disease (<em>Armillaria mellea</em>), and
needlerust (<em>Melampsora parlowii</em>), accelerate the rate and
extent of hemlock mortality.<br />
<strong>Hosts</strong><br />
The hemlock woolly adelgid develops and reproduces
on all species of hemlock, but only eastern and Carolina
hemlock are vulnerable when attacked. The range of
eastern hemlock stretches from Nova Scotia to northern
Alabama and west to northeastern Minnesota and eastern
Kentucky. Carolina hemlock occurs on dry mountain
slopes in the southern Appalachians of western Virginia,
North and South Carolina, Georgia, and Tennessee. Eastern
hemlock is also commonly planted as a tree, shrub, or
hedge in ornamental landscapes. At least 274 cultivars of
eastern hemlock are known to exist.<br />
<strong>Description</strong><br />
The hemlock woolly adelgid is tiny, less than 1/16-inch
(1.5-mm) long, and varies from dark reddish-brown
to purplish-black in color. As it matures, it produces a
covering of wool-like wax fi laments to protect itself and its
eggs from natural enemies and prevent them from drying
out. This “wool” (ovisac) is most conspicuous when the
adelgid is mature and laying eggs. Ovisacs can be readily observed from late fall to early summer on the underside of
the outermost branch tips of hemlock trees (figure 1).<br />

The hemlock woolly adelgid is parthenogenetic (all
individuals are female with asexual reproduction) and has
six stages of development: the egg, four nymphal instars,
and the adult. The adelgid completes two generations a year
on hemlock. The winter generation, the sistens, develops
from early summer to midspring of the following year
(June–March). The spring generation, the progrediens,
develops from spring to early summer (March–June). The
generations overlap in mid to late spring.<br />
The hemlock woolly adelgid is unusual in that it enters a
period of dormancy during the hot summer months. The
nymphs during this time period have a tiny halo of woolly
wax surrounding their bodies (figure 2). The adelgids
begin to feed once cooler temperatures prevail, usually in
October, and continue throughout the winter months.<br />
The ovisacs of the winter generation contain up to 300
eggs, while the spring generation ovisacs contain between
20 and 75 eggs. When hatched, the fi rst instar nymphs,
called crawlers, search for suitable feeding sites on the
twigs at the base of hemlock needles. Once settled, the
nymphs begin feeding on the young twig tissue and
remain at that location throughout the remainder of their
development. Unlike closely related insects that feed on
nutrients in sap, the hemlock woolly adelgid feeds on stored starches. These starch reserves are critical to the
tree’s growth and long-term survival.<br />
Dispersal and movement of hemlock woolly adelgid occur
primarily during the fi rst instar crawler stage as a result
of wind and by birds, deer, and other forest-dwelling
mammals that come in contact with the sticky ovisacs and
crawlers. Isolated infestations and long-distance movement
of hemlock woolly adelgid, though, most often occur as the
result of people transporting infested nursery stock.<br />
<strong>Control</strong><br />
Cultural, regulatory, chemical, and biological controls
can reduce the hemlock woolly adelgid’s rate of spread
and protect individual trees. Actions such as moving
bird feeders away from hemlocks and removing isolated
infested trees from a woodlot can help prevent further
infestations. State quarantines help prevent the movement
of infested materials into noninfested areas.<br />
Chemical control options, such as foliar sprays using
horticultural oils and insecticidal soaps, are effective when
trees can be saturated to ensure that the insecticide comes in
contact with the adelgid. Several systemic insecticides have
also proven effective on large trees when applied to the
soil around the base of the tree or injected directly into the
stem (figure 3). Chemical control is limited to individual
tree treatments in readily accessible, nonenvironmentally
sensitive areas; it is not feasible in forests, particularly
when large numbers of trees are infested. Chemical
treatments offer a short-term solution, and applications may
need to be repeated in subsequent years.<br />
The best option for managing hemlock woolly adelgid in
forests is biological control. Although there are natural
enemies native to Eastern North America that feed on
hemlock woolly adelgid, they are not effective at reducing
populations enough to prevent tree mortality. Therefore,
biological control opportunities using natural enemies
(predators and pathogens) from the adelgid’s native
environment are currently being investigated. Several
predators known to feed exclusively on adelgids have
been imported from China, Japan, and Western North
America and are slowly becoming established throughout
the infested region (fi gure 4). It will likely take a complex
of natural enemies to maintain hemlock woolly adelgid
populations below damaging levels. Efforts to locate,
evaluate, and establish other natural enemies continue.<br />
