The meeting opened at 7:30
Amy Smagula, a limnologist
and Exotic Species Program Coordinator with NH DES, presented information
about the milfoil in Long Pond. She introduced herself and explained
that she heard one month ago about the milfoil in Long Pond. She
asked those present when they first noticed this plant. She said
that she did a full survey of the pond and suspects that it has been
growing there for close to three years.
She described the plant, variable
milfoil, and showed photographs of what an infestation looks like.
She explained that it grows wherever sunlight can reach the floor of
the waterbody, usually to about 10’ deep, but it has been seen in
water as deep as 23’.
She also showed a photograph
of fanwort and advised those present to be on the lookout for this plant
as well. She described the structure of fanwort as having opposing
fan-shaped leaves whorled on the stem, which can grow up to be 10’-15’
long.
Mrs. Smagula had mapped the
areas where the milfoil was found. It equals about 20 acres total,
mostly on the southern shorelines around the pond. She explained
that treatment entails an herbicide followed by other techniques such
as hand-pulling or suction.
Based on her site assessment
she would like to put together a long-term management plan. She
can’t promise that the pond will be rid of it forever, as there are
few success stories in that regard, but the management of milfoil is
highly probable. The written plan will include a summary of the
pond describing the ecology and biology of the water.
Mrs. Smagula encouraged the
residents to start a water quality monitoring program. They have
a Volunteer Lake Assessment Program in which volunteers can be trained
to go out once per month to collect water samples which are then sent
to Concord for analysis. They will issue a mini-report every year
based on these samples. This will give the residents a long term
trend analysis. Water quality is very important; as more nutrients
are added to the water, more plants will be growing.
She will help establish goals,
which include control and hopefully eradication. She explained
different methods with their probable level of success in Long Pond.
| Restricted use area-with the ring of milfoil around the pond, this is not feasible. This may be possible some day if it can be contained to one area. | no |
| Fragment barrier-this contains the pieces and keeps the pieces from drifting to other areas. | maybe |
| Hand-pulling-this can’t be done now as there is too much. | yes |
| Diver-assisted suction-this is a super sized vacuum that sucks up the root system. This is limited on the size of infestation. | possible |
| Benthic barrier-these are like window screens that are staked to the bottom which compress the plant to the sediment. This prevents them from being broken off. These are expensive. The compression also produces gasses which will make the structure balloon from the bottom of the lake. This is not feasible for large areas; they like to only do a 20’x14’ area. | possible |
| herbicide-This is recommended. | yes |
| extended drawdown-this is also not feasible. The milfoil turns into little cacti during drawdown. This doesn’t work for milfoil. | no |
| dredge-this would cost millions. | no |
| bio control-there is a weevil that eats some milfoil, but not variable milfoil. UNH is looking at a type of worm that eats variable milfoil. Further research is being done to ensure this worm will work. | none available |
| no control-if no control is taken, the lake can be lost. | no |
As the herbicide treatment
is recommended, Mrs. Smagula explained this method. She said they
do about 20-25 treatments in the state every year on different water
bodies. They have been doing these treatments since the 60’s
using licensed applicators. She said these are proven methods
and safe.
Mrs. Smagula recommended treatment
begin in spring of 2009. They use 2,4-D which kills the plant
and the roots. Lily pads and other things will not die.
It does not bio-accumulate like DDT and has no reproductive issues.
In addition to the herbicide, they would like to start a weed-watcher
volunteer program. This would allow someone to be trained to monitor
sections of the water body. If milfoil is seen, an email can be
sent to Mrs. Smagula who will then send a diver to do bottom-area work
so that an herbicide treatment will not have to be done again.
She explained that management
entails treatment, monitoring, and follow-up. She said that as
in a lawn, you can’t mow it once and expect it to never grow again.
In 2010 Mrs. Smagula will see
if a follow-up herbicide treatment is needed. After that it would
be several years before another treatment is probably needed.
Meanwhile other techniques are used to control the milfoil. During
2010 weed watching will continue in conjunction with diving and hand-pulling.
This method continues in subsequent years.
Mrs. Smagula explained that
the herbicide treatment can’t start now because the plants need to
be actively growing to take the herbicide into the root system.
There is also a period of time that the water should not be used following
an herbicide treatment. The Department of Agriculture sets a restrictive
area within 1200’ of the treatment zone. Domestic purposes,
such as showering and washing dishes, should not be done until the concentration
reaches 70 parts per billion. She said she will look into this
and have details in the management plan. There is probably a
7 day swim restriction and a 2 week domestic use restriction.
Treatment will start in late
May to early June. There is usually a 30 day restriction for watering
a lawn but an early test can be pulled to see if the concentration is
safe to use. This affects all kinds of wells: point, dug, and
artesian wells.
The dam was discussed.
The herbicide can be used in flowing conditions. Mrs. Smagula
described the herbicide as something like kitty-litter. It is
a time-release and is sprinkled around the plants via a hopper and the
pellets sink to the bottom. This is more effective than a fluid
which does not necessarily reach the roots.
The state has a policy that
when an herbicide treatment is done for an infestation, the state pays
100% for the first treatment. After that, they can match 50% if
more treatments are needed. These are usually paid through warrant
articles or lake associations.
A rough estimate of the cost
for treating 20 acres can be about $25,000-$30,000. Mrs. Smagula
estimated that for a follow-up treatment, considering reduced acreage
and a matching grant, the town would pay roughly $6000-$8000.
Nitrogen and phosphorus are
the nutrients that nourish the lake. Mrs. Smagula explained that
with increased development, road run-off, septic failure, lawn fertilizers,
etc., the lake is fertilized. There is an extensive wetland at
one end of the lake which, at different times of the year, either takes
up or gives off nutrients. It is not just the immediate abutters
who affect the lake quality. She said to think of the watershed
as a funnel. Everything within that funnel runs off into the lakes
and ponds. It is important to reduce nutrient loading in that
watershed in order to maintain the water bodies as best as possible.
There was a question about
whether the state has a program which requires boat owners to purchase
a noxious weed stamp that provides funding for the very work Mrs. Smagula
is doing. Mrs. Smagula explained that right now their funding
comes through boat registration. There was a bill that died on
the senate floor two years ago. That bill will be re-introduced
this year.
It was suggested that since
NH has a great pond law, guaranteeing fishing on any body of water larger
than 10 acres, and the state has a public boat launch on the pond, the
cost and managment should be a complete state responsibility.
Mrs. Smagula did not disagree but said there are too many boat launches
and too little funding presently for the state to monitor every launch
all the time. The launches are staffed during high-use times,
such as fishing derbies, etc. She said this underscores the importance
of a volunteer program to help monitor the invasive species.
Mrs. Smagula said that the
monthly testing can be around $50 per month. Funding of the management
and control was discussed. Mrs. Smagula will be able to keep the
Conservation Commission and other interested parties apprised of the
progress the bill makes this year.
Mrs. Smagula said the best
way to control spreading of the invasive species from one body of water
to another is to look carefully around the boat and trailer and manually
get rid of any plants seen. She suggested looking in the wheel
wells, around the license plate and all around the trailer and hull.
The herbicide does not bio-accumulate,
meaning it does not build up in the tissue or fat. Fish will take
it in but excrete it out. It does not affect the insects either.
The herbicides used are called Aqua-clean or Navigate, with the latter
being used more often.
Mrs. Smagula asked to get contact
information for those in attendance. She can email the management
plan and fact sheets about 2,4-D as well as other literature that may
be of interest. She will send hard copies to the town hall also.
Mrs. Smagula was asked about
the bill that is being sent through Concord. She said she thought
it is being lobbied by the senate environment committee. She can
keep those in attendance informed of when the bill is introduced.
She will also work with Kingston.
She gave her contact information.

Chris asked those in attendance
if it is their consensus that we move forward with this project in spite
of any inconvenience involved. There was positive response from
the audience. Jason agreed to head up the volunteer program.
Mr. Fries spoke about the phosphates
flowing into the water, and subsequent abundance of vegetation, as a
companion problem to the milfoil. He said that this is something
that the Conservation Commission will have to address soon. Mrs.
Smagula said that native vegetation is slower growing than exotic species
like milfoil. Through the volunteer program, the inflow of nutrients
can be monitored and then where the nutrients are coming in can be pinpointed.
If the native plants become too abundant, there are management techniques.
Mrs. Smagula said that the
plants can be cut above the sediment to clear a path to the water.
Pulling the plants is not recommended as it disturbs the sediment.
The education of the public, about run-off and lawn fertilizers, etc.,
was discussed. The importance of establishing barriers, especially
natural barriers, was discussed briefly.
Mr. Caparco said that his property
includes a flooded meadow. He was told years ago the dam was lowered
and his field was hayed. Some audience members recalled that happening
years ago. Jason asked if this is a worthwhile method that the
residents would be amenable to in spite of the inconvenience.
Mrs. Smagula said this is another method that can be explored.
Mr. Caprco asked about fertilizers.
Mrs. Smagula said within 25’ of the lake edge no fertilizers are allowed
at all, except limestone. She suggested watering the lawns with
lake water.
The contact information of
those present will be sent to Mrs. Smagula.
Barbara S. Byrne and Butch
Sanborn presented a map showing three lots equaling about 23 acres that
they are not interested in owning any more. They wanted to know
what options were open to them. They offered these lots for the
Conservation Commission’s consideration.
They were told they can sell
the property outright, they can sell the building rights and maintain
ownership, or they can put a conservation easement on the property.
They asked what would happen
if it is sold to the Conservation Commission. They were told that
the Commission is currently trying to put management plans on their
properties and put them into the Easement.
Laura explained the stewardship
plan and what it does. She said priorities would be made for what
is desired for a particular piece of property. This can be for
forestry, wildlife, recreation, maple syrup, etc. depending on its location
and attributes. Right now the Sanborn land is used for haying.
It can be kept for haying if that is their desire.
They are in the process of
getting it appraised. It is not their desire to add to schools
and traffic by selling it for building lots. Sheila said she has
information that explains the different options and will get that information
to them.
They will provide the Board
with a copy of the appraisal.
The budget is due mid-month.
The different line items were discussed.
It was decided that the matching
grant fund will be $800.
The wetland evaluation was
discussed. Laura talked about Mark West who has done this sort
of thing for Nottingham and Epping. There also may be another
school that can help with this project. Chris suggested taking
the $800 allotted for matching grants and using it to purchase a bulletin
board.
Laura asked if the wildlife
corridor study being done is a land prioritization. She said Tracy
Degman did a study several years ago. This was a land prioritization
and was very methodical. However, this was not a wildlife corridor
study. This is how the list was made of different pieces of property
that were considered for purchase. The natural resource inventory
may also have information that would help identify pieces of land ideal
for purchase.
Chris said that the amounts
in the budget need to be justified. Sheila expressed her opinion
that she does like the idea of another board relying on another boards’
budget to take care of their minutes. She said that is not fair
to the other committees.
Chris said that the Planning
Board is financially responsible for updating the Master Plan.
Dues will remain at $225.
Laura mentioned that it may be a good idea to make sure the cost will
not increase.
Postage will be set at $100
as more mailings are expected to be sent to Long Pond abutters.
New manuals are needed.
The cost will be researched as well to see whether or not new editions
are due next January. This line will be left blank until that
information is found.
Project expenses were discussed.
There was a discussion about putting together educational information
to be mailed and other potential projects. This line will be $800.
Mileage reimbursement will
be increased to $40.
Educational equipment was added
to the ’07 because it was going to be used for the display board.
This will be $800.
Matching grant funds were discussed
again. Chris reminded the board members that these items need
to be justified. Chris will call Ellen Snyder about the cost of
a land prioritization schedule.
There was a discussion about
the Stewardship Plan and Easement. The issue of motorized and
non-motorized issue was discussed. It was agreed that snowmobiles
have a lower impact than other motorized vehicles. The problem
occurs when the snowmobiles go through areas that are not frozen.
Bruce Schwaegler seemed to think the Easement was supposed to forbid
all motorized vehicles in the town forest. Chris said that if
snowmobiles are allowed, once the easement is in place, the town will
be responsible for any damages done. This will be brought up at
the next joint meeting.
The shooting issue is still
being researched. Chris said that rather than a Planning Board
issue, this is a Selectman issue. Judy and Laura said there is
evidence that there is shooting all over the place, not just the old
gravel pit. Judy said it would be sad to wait until someone gets
shot before this is addressed.
Laura is focusing on land purchase
grants.
This was discussed tonight.
Upon review of the aforementioned land prioritization there may be other
parcels of interest to include.
Chris explained to the Board
members that Hoyt Builders is donating a parcel of land to the town.
The map was reviewed. This is a lot-line adjustment, making the
town forest a little larger. The parcel equals approximately 18
acres. Tags will be purchased and placed by the developer to mark
the forest boundary. There will also be a 50’ strip of land
to allow access to the property.
The Board talked about getting
other markers for the town forest. Chris will get the prices and
put that in the budget.
Lot access for Terra Realty
was discussed. Chris spoke with Tom Waters to see if there is
access through his property. There is not. This leaves the
powerline corridor as the only other known means of access. There
may be other options, or they will have to use Tuckertown Road.
They will have to go before DES to get a wetlands crossing permit.
The question was asked if another
entrance can be enforced, rather than using Tuckertown Road. There
was a discussion about why Tuckertown Road was part of the agreement.
The minutes from the July 17th
were discussed. Judy moved and Chris seconded a motion to accept
the minutes as written. Sheila and Laura abstained. The
motion passed.
Since the discussion will involve
consideration of land purchase which, if discussed in public, might
benefit a party whose interests are adverse to those of the general
community RSA 91-A: 32d should warrant nonpublic session, at 10:25pm
Judy moved and Laura seconded a motion to go into non-public session
per RSA 91-A: 32d. The Commission was polled and the decision
was unanimous in the affirmative.
At 10:55pm Judy moved and Laura
seconded a motion to close the non-public session and return to public
session.
Judy moved and Laura seconded
a motion to seal the non-public minutes of September 4th,
2008.
At 11:00pm Laura moved and
Sheila seconded a motion to adjourn. The motion passed.
