Lexington’s Rich Resources
The town of Lexington is fortunate to have more than 1,300 acres of conservation land that has been
protected in perpetuity and placed in the care of the Conservation Commission. This conservation
land covers over 10% of the town, an impressive figure for a community so close to metropolitan
Boston. Add to that town-owned conservation land the open space that is provided under other
ownership, such as Lexington’s Recreation department, Minuteman National Historic Park, the
Massachusetts Department of Conservation and Recreation, and Arlington’s Great Meadow, and the
total area of Lexington covered by open space rises to nearly 20%.
Conservation land and other open space enhances the quality of life for residents and visitors in a
variety of ways. It protects the flood control capabilities of wetlands, preserves water quality in streams
and ponds, protects wildlife and plant habitat, forestalls problems of overly dense land development,
and helps preserve the historic character of the Town. Natural open space also provides opportunities
for recreational and educational experiences that are rapidly disappearing from the suburban
communities of eastern Massachusetts.
Protection of open space does not end at simply safeguarding the property from development.
Protection is a continuing need involving maintenance, monitoring, and care, toward which very
limited municipal and state resources are available. The Lexington Conservation Stewards was found-
ed in the early 1980’s to provide a base of citizen volunteers who could help to complement the town
Conservation Division’s stewardship of its natural open space, particularly town-owned
conservation land. These volunteers—the Stewards—work to monitor the condition of conservation
land, remedy problems when they are identified, and promote public responsibility and commitment
toward our natural open space.

Lexington’s Conservation Stewards
Who are the Stewards?
Members of the Lexington Conservation Stewards are citizens who care for Lexington’s conservation
land and other natural open space. Some attend work days to help build boardwalks and restore
meadows. Some carry a trash bag and pair of clippers with them when they go for a walk on a
Lexington trail. Some apply for grants, help to monitor streams, or take students on educational walks
through the woods. The Stewards’ primary focus is on town-owned conservation land, but they
contribute to caring for other open space as well. Whatever their level of involvement, Stewards are
keeping an eye and a helping hand on our conservation land.
How are the Stewards organized?
The Lexington Conservation Stewards serves as
a volunteer organization of Lexington’s
Conservation Commission, working closely with
the staff in the Conservation Division office to
plan and carry out stewardship activities on
town-owned conservation land. They also
work with other partners to steward other open
space that is not under the town’s Conserva-
tion Division. Individual Stewards carry out
certain activities on their own, while group
workdays are more suited for other projects.
A volunteer board, called the Steward
Directors, oversees stewardship projects and
reports to the Conservation Commission. The
Steward Directors accept new members to this
leadership body on a rolling basis. The Conser-
vation Commission is the final decision-making
authority for all questions related to the
operations of the Stewards.
The Steward Directors meet approximately
monthly, and their responsibilities include:
identifying priorities and major projects
coordinating volunteer workdays to implement projects
recruiting and supporting other Stewards
hosting events, producing a newsletter, and fundraising
contributing to the Conservation Division’s land management plans
working collaboratively with other organizations on projects of mutual interest

Lexington Conservation Stewardship Handbook 5
What can individual Stewards do to help?
Some of the ways that individual Stewards can help out with the care of our conservation land are:
Visiting nearby conservation areas often to monitor for changes or potential issues
Picking up and properly disposing of trash that others have left behind
Volunteering on a scheduled workday
Pruning back branches and removing other blockages to established trails
Notifying the Conservation Division of issues that are too big to handle personally, such as
downed trees over trails, illegal dumping, and encroachment
Serving as a primary contact person for a specific conservation area (see Appendix 2)
Talking to friends about Lexington’s conservation land and other open space
See the next section, Guidelines for Stewardship Efforts, for more details on these tasks.
Taking Leadership as a Steward
For those Stewards who would like to take an extra step to get more involved, there are a number of
options, such as:
Propose ideas for enhancements to existing conservation land (e.g. a new trail, meadow
restoration) to the Steward Directors or to the Conservation Commission.
Lead a work day. For projects that would benefit from a larger, organized effort, workdays can
do the trick. The Conservation Division can work with you to get approval for your workday
project, advertise for volunteers, and assist you in implementing an effective workday. When
proposing a project, think about the number of volunteers that would be appropriate and the
types of tools you would need to get the job done.
Lead a walk to introduce people to your favorite area. Citizens for Lexington Conservation,
which is another conservation organization in town, hosts a spring and fall walk series, through
which you can lead a walk. Visit their website at: www.lexingtonma.org/clc/HomePage.htm.
Provide information to other visitors. Encourage enthusiastic visitors to join the Lexington
Conservation Stewards by going to the web site or contacting the Conservation Division
Join the Steward Directors. Contact a current Director or the Conservation Division to find out
about opportunities for joining this coordinating board.
How can I become at Steward?
It’s easy, and free! To join the Lexington Conservation Stewards, visit our website at
www.lexingtonma.gov/conservation/stewards.cfm. Download the membership form available there
and return it to the Conservation Division at 1625 Massachusetts Avenue, Lexington, MA 02420, or
contact the office directly for a membership form. Membership provides copies of our newsletters;
invitations to Stewards’ gatherings; email notification of upcoming stewardship events, projects, and
news; and opportunities to work together with other town residents on issues of mutual interest.

Guidelines for Stewardship Efforts
Stewards can be extremely helpful in caring for our conservation lands by performing low-key
maintenance on a frequent basis. Much of this maintenance can be done individually during casual
walks or visits to conservation areas, while other work needs organized workdays to get the job done.
This section details guidelines for the most common Steward efforts, including:
Trash Clean Up
Routine Trail Maintenance
Monitoring and Reporting
Invasive Species Removal
Trash Clean Up
It is unfortunate but true that a reliable supply of
trash continues to appear in our conservation and
open space area, so regular clean-ups by
individuals or organized workgroups is one of the
most important activities that Stewards can
perform. This trash is not only unsightly, but it can
also pollute water and soil and pose threats to
wildlife.
Often, individual Stewards picking up trash on their
own does the trick, but occasionally, trash
problems are too large for individuals alone, and
workdays or a report to the Conservation Division
are more appropriate solutions. You can work with
the Conservation Division to set up a work day.
Trash Disposal
Small amounts of trash collected by individuals can often be put out with the Steward’s
weekly trash pick up. On workdays, if a small number of bags of trash is collected, the
volunteers can often distribute the bags among themselves to be left at their curb for week-
ly pickup.
For larger amounts of trash, contact the Conservation Division to schedule a pick-up by the
Town. When possible, move the trash to the side of a nearby truck-accessible road and pile
it so that it is not an inconvenience or danger to visitors and neighbors.
When very large amounts of trash are anticipated, the Conservation Division may be able
to arrange to have a dumpster delivered to the site for the workday, so that collected trash
can be deposited directly in the dumpster.
Helpful Tools for Trash Clean Ups
Work gloves to protect against broken
glass & metal, unsanitary garbage, and
thorns
Trash bags
Clothing that covers arms and legs to
protect against thorns, poison ivy, and
ticks
Waterproof boots or old shoes if
removing trash from wet areas

Hazardous Materials
Hazardous materials (hazmats) are materials that can harm people or the environment. Many
familiar hazmats can be removed by volunteers if done carefully to prevent spillage. If fresh
leakage is evident, if you are in doubt about what to do, or if you encounter unfamiliar
materials, mark and record the location of the item and contact the Conservation Division. Some
familiar hazmats include:
Household pesticides and fertilizers
Paint
Batteries
Oil filters
Oil containers
Heating oil tanks
Refrigerators and air conditioners

Routine Trail Maintenance
Lexington is home to more than 60 miles of trails, and
keeping these trails clear so that visitors can use them
comfortably is an on-going task. Some trails may only
need to be pruned and cleared once per year, but
others need more frequent maintenance.
Routine trail maintenance tasks include:
Clearing downed trees and limbs that block
established trails or pose a safety hazard
Pruning/trimming vegetation that overhangs trails
Mowing meadow trails
Trimming vegetation around signs and
kiosks so that they are clearly visible
Reporting chronically wet trails to the
Conservation Division

What should I know before I maintain a trail?
Don’t build new trails, however “small”. Trails need to fit into a larger plans for the
conservation area and need proper planning themselves to be sustainable. If you have
a new trail idea, contact the Conservation Division or a Steward Director to
discuss it. The creation cycle of a new trail is typically about one year.
Don’t open up a heavily overgrown or blocked trail until you have confirmed with the
Steward Directors or Conservation Division that the trail is not closed.
Don’t rake trails. Leaves, pine needles, and other organic matter build forest soil,
absorb water, and prevent erosion. Leaving them in place helps the trails to last over the
long-term.
Don’t mark or blaze trails. All trail marking must be approved by the Conservation
Division.
Don’t dump fill or wood chips on trails without permission from the Conservation Division.
Don’t apply herbicides or pesticides anywhere on town-owned land. On municipal land,
law dictates that these chemicals must be applied by a certified applicator and only
with appropriate permits.
Lexington Conservation Stewardship Handbook 9
Monitoring trails to ensure that new ones are not being created without permission and that closed
trails remain closed
Permission
For light pruning/trimming and removal of downed limbs or trees across trails, Stewards can proceed
without seeking approval from the Steward Directors or Conservation Commission, as long as the trail is
on a conservation area (if questionable, please contact the Conservation Division). For larger projects,
such as creating new trails, Stewards should contact the Conservation Division to discuss the project.
Trail Appearance
A well-maintained trail should look natural, with few visible cuts on bordering vegetation. All cut
branches and brush should be moved well off the trail with the cut end pointing away from the trail.
Trail Width and Height
Trails should generally be trimmed to the following widths from ground level to the highest overhead
reach while standing on the ground:
Singletrack with normal trailside vegetation: 4 feet (both elbows outstretched)
Singletrack if trailside vegetation is thorny, allergenic (poison ivy), rapidly growing, or
invasive: 6 feet (both arms outstretched)
Doubletrack minimum: 8 feet
Doubletrack for easy passage of any sized service vehicle: 11 feet
Better visibility around curves reassures users about what is ahead and reduces conflicts between
visitors. For example, faster traffic can slow down
when approaching slower traffic. By selectively
pruning growth on the inside of curves, good visibility
can be maintained without overly widening trails.
Intersections are a common stopping point for visi-
tors to rest, navigate, or socialize and should be
trimmed wider than trails to accommodate these
needs and reduce conflicts involving faster traffic.
So trails will remain passable all winter, overhead
clearance should be as high as can be achieved by
workers standing on the ground (approximately 8
feet) to allow for deep snow cover and branches
weighted down with snow and ice.
Removing Blowdowns
Blown down trees and limbs should be removed as
soon as possible from trails where they present a
hazard of falling on visitors or block the trail in such a

Pruning Hints
When pruning vegetation along a trail, the most important rule of thumb is to leave as little
evidence of the pruning as possible. The goal of pruning should be a trail that is free of
protruding branches and looks natural. Debris from pruning—twigs, branches, and leaves—
should be moved off of the trail so that no sign of the job remains.
A bounty of information on proper pruning practices can be found in books and online; the
following is just a brief primer on the subject.
Why Pruning Technique Matters
Pruning the branches of trees and shrubs
must be done properly so that the cuts
heal correctly and do not impact the
plant’s health. Improper cuts can lead to
disease and even death of the plant.
Proper pruning cuts are made only where
one branch or twig attaches to another
(called the node), never along the length
of the branch. The area of the plant
where a branch meets a trunk or other
branch is called the branch collar. The
raised bark that develops in this crotch is
called the branch bark ridge (see figure
1).
Cuts into either the branch collar tissue or the branch bark ridge tissue will not heal properly,
allowing for diseases to enter and threaten the plant’s health. Cuts that leave too much of a
stub also promote disease. Proper pruning, made at the node but not entering into the branch
collar tissue or branch bark ridge, allows tissue to grow over the cut, eventually walling off the
wound with a protective layer of bark.
Proper Cuts
When pruning large or small branches, cuts must be made outside of the branch bark ridge and
branch collar area, angling away from the trunk but staying as close as possible to the collar. This
leaves a smaller cut but no stub. There is no standard angle for a proper collar cut, but the final
cut should:
Minimize the branch stub
Leave the branch bark ridge and branch collar intact
Minimize the overall size of the pruning wound Diagram courtesy of the U.S. Forest Service. Figure 1. Branch collars and branch bark ridges.
Lexington Conservation Stewardship Handbook 11
When cutting smaller branches, make the
cut as close as possible to the trunk (or
larger branch) but outside the branch
bark ridge (see figure 2).
For large limbs, stub cut the branch, a
technique that minimizes the chance of
the bark tearing down the trunk and
creating a wound that is difficult to heal
(see figure 3). Stub cutting uses three
cuts, the first two cutting off most of the
branch but leaving a portion of 1-2 feet
remaining for the final finish cut.
The first cut undercuts the branch 1-2 feet
out from the parent branch or trunk. This
cut eliminates the chance of the branch peel-
ing bark as it is removed. The second cut is the
top cut, which is usually made slightly further
out on the branch than the under cut. This al-
lows the branch to drop smoothly. The third or
finish cut removes the stub. The finish cut
should be made outside of the branch bark
ridge and branch collar areas, leaving a
smooth surface with no jagged edges or torn
bark. Use tools that are sharp enough to cut
without tearing.
Do Not Paint Cuts
Painting pruning cuts with wound dressing is
not advisable. Wound dressings have been
found to promote rather than prevent wood
decay.
Proper Timing
The ideal times to prune most woody plants
are in late winter or early spring (February,
March, early April) or well into the growing
season. Cuts made during the growing season
may attract insects that carry diseases or allow
fungus invasion. Avoid pruning when buds are
opening and during early leaf season.

trail.
Safety During Trail Maintenance
While working on trails, the following guidelines should be followed:
Thorny cuttings should be scrupulously removed from the trail to protect dogs, small children, and
bicycle tires.
Saplings should be cut as close to ground as possible to avoid creating tripping hazards.
Limbs should be cut back to the main trunk or branch whenever possible to reduce the risk of
visitors injuring themselves on protrusions.
When not in use, sharp tools (saws, pruners, etc.) should be kept away from the trail, in a visible
location, and with the sharp edge covered to safeguard against accidents.

Monitoring and Reporting
Many Stewards are regular visitors to Lexington’s
conservation land and therefore can serve a look-
outs for those areas. In this way, monitoring
combines outdoor recreation with practical public
service. Your monitoring reports can provide
information that the Conservation Division or
police couldn’t collect alone.
Monitoring is a simple task. On your normal visits to
conservation areas, take note of any observations
you make (see What to Look for When Monitoring
sidebar), include a precise location description,
and submit them to the appropriate office (see
Who to Report To below). Often, a photograph is
also helpful for describing the report.
Who to Report To
Contact information for the agencies listed below
are available in Appendix 1 (page 18). In general,
follow these guidelines for deciding who to report
your observation to:
For urgent safety-related emergencies, call
911.
For non-emergency illegal activity in progress
(such as partying or unauthorized tree-
cutting), contact the police or fire non-
emergency line and follow up with a report
the Conservation Division.
For other observations (such as dump sites,
encroachment, etc.) contact the
Conservation Division.
How to Report
When reporting to 911 or the police or fire non-
emergency lines, a phone call is the best way to
report. When reporting to the Conservation
Division, use phone, email, or paper mail,
depending on which you find most convenient.
What to Look For When Monitoring
Unusual changes in natural or
human-made features
Unusual wildlife, plants, or other notable
natural features
Evidence of illegal or illicit activities, such
as underage drinking, fires, unauthorized
motor vehicles, hunting or trapping,
shooting, or disposal of pollutants
Emergency situations, such as personal
injuries or crimes in action (you will rarely
see these, but please report them
immediately to 911 when you do)
Improper cutting or destroying of
vegetation (pruned trails, as described in
the previous section, are OK)
Large deposits of trash or landscaping
debris
Vandalism
Digging of holes
Any type of construction
Encroachment onto conservation land
by neighboring properties
Overgrown trails that you cannot trim
yourself
New trails being created
Broken boardwalk sections
Trails that are chronically wet or muddy
outside of the spring wet season
Other issues that you consider to be
worth reporting
Lexington Conservation Stewardship Handbook 14
Invasive Species Removal
Invasive species pose significant threats to the habitats in Lexington’s fields, forests, and wetlands.
Invasive species are plants, animals, or other organisms that:
1. are non-native (or alien) to the ecosystem under consideration and
2. whose introduction causes or is likely to cause economic or environmental harm or harm to human
health (National Invasive Species Information Center, www.invasivespeciesinfo.gov/whatis.shtml).
The Lexington Conservation Stewards work to control invasive species by eliminating them where
possible and limiting their expansion where elimination is impractical. In most cases, these are not easy
tasks. Removal efforts are labor intensive and often require repeated efforts over a few years. Removal
always need to be followed up by monitoring and, in some cases, planting of native species or other
forms of restoration. Invasive species-related efforts take planning and diligence, but they are
extremely important efforts for native biodiversity.
In this section, we focus on three of Lexington’s most pervasive invasive species: Garlic mustard (Alliaria
petiolata), Japanese knotweed (Fallopia japonica), and Oriental bittersweet (Celastrus orbiculatus).
This is not to say that other invasive species do not exist in Lexington—they do, and in great
number (Multiflora rose, Japanese honeysuckle, European and Glossy buckthorn, Burning bush,
Japanese barberry, Norway maple, and Tree-of-Heaven are but a few). Many resources are available
for identifying and recommending control methods on the various invasive species in Massachusetts.
For more resources on invasive species, see Appendix 3, Recommended Resources.
Before You Start an Invasive Species Removal Project
Herbicides and pesticides cannot be applied on public land unless the applicator has a license
and application has been approved by the Conservation Commission.
In order to remove invasive species from a wetland, you first need to get approval from the
Conservation Commission, because removal can cause erosion into the wetland.
Do not undertake an invasive species removal project unless you can commit to following up for
a few years. In some cases, a single cutting of invasive species can actually stimulate growth,
making the problem worse. Repeated cuttings over a few growing seasons can weaken and
eventually kill the plant.
Plan for proper disposal. Most invasive species can re-sprout or re-seed themselves after being
cut or pulled if they are left outside. Invasive species debris needs to be disposed of in closed
plastic bags or burned on site (for burning options, contact the Conservation Division).
To avoid mistakes, learn to identify your invasive species well and check to see if there are
similar-looking native species to the invasive species you want to tackle before you begin
removing it.
Lexington Conservation Stewardship Handbook 15
Garlic Mustard (Alliaria petiolata)
Plant description: Garlic mustard is a biennial herbaceous plant with first year plants setting small
rosettes of leaves that lie close to the ground and often go unnoticed. Second year plants raise their
flower stalks to set seed and are most recognizable. Flowers are small and white. Leaves have large,
noticeable teeth. Crushed leaves smell garlicky.
Where it grows: Moist, shaded soils and disturbed areas.
Threat: Many native spring wildflowers, such as spring beauty, wild ginger, bloodroot, Dutchman’s
breeches, hepatic, toothwort, and trillium, are suppressed by garlic mustard.
Mechanical control methods: Remove garlic mustard in the spring from mid-April until late May, when
pulling the plant by the roots is easiest as the soil is typically moist from spring rains. Removal in the
spring also catches the plant before it has flowered and before seeds can be dispersed. Grasp the
plant at the base of the stalk and gently pull the roots from the ground. With practice, the whole root is
easy to remove. Be sure to pull the root even if the flower stalk breaks off, as garlic mustard can
generate new growth from imbedded roots. When clearing an area, remove every specimen that is
visible. Leaving only a few plants will generate enough seed to repopulate a cleared area the
following season. If first year growth plants are noticed during removal of the second year plants, it is
often best to leave them until the following season. The root structure of the first year plants is not as
robust, often resulting in removal of the leaf rosettes only, leaving the roots in the ground. Dispose of at
least the roots and flower heads in plastic bags (the stems can be left to decompose if necessary).
Lexington Conservation Stewardship Handbook 16
Japanese Knotweed (Fallopia japonica)
Plant description: Japanese knotweed is a familiar bamboo-like perennial, often growing to more than
10 feet tall in dense stands. Its stems are hollow and its flowers are tiny and greenish-white. It spreads
via rhizomes, making it particularly hard to eradicate.
Where it grows: Near water, in low-lying areas, waste places, and disturbed soil.
Threat: Forms tall, dense stands particularly in riparian areas, where it can often survive flooding that
other native plants do not. Very difficult to stop from spreading.
Mechanical control methods: Attempting to uproot the plant is not advised, as even small pieces of
the rhizomes are capable of regeneration. The best method for mechanical control is to cut the plant
to the ground every time it grows more than 1-2 feet high. When cutting the stalks, cut flush with the
ground, leaving no protruding stumps. Another strategy involves laying black plastic over the cut
stems to deprive the plant of light, but projects of this type can be more complicated and should be
approved by the Conservation Division first.
Lexington Conservation Stewardship Handbook 17
Oriental Bittersweet (Celastrus orbiculatus)
Plant description: Oriental bittersweet is a vine that is most recognizable by its berries, which open from
orange to red as they ripen and are sometimes favorites for creating fall wreaths. The vine is vigorous,
can bring down trees, and blankets areas where it invades, often mixing with multiflora rose and
poison ivy.
Where it grows: Forest edges, woodlands, fields, and disturbed areas.
Threat: Kills trees and topples them. Threatens to completely displacing native American bittersweet.
Mechanical control methods: Young vines can be uprooted by hand with care to pull out as much of
the root as possible. The uprooted vines can be dispersed in the surrounding underbrush to
decompose. Return visits to the cleared area later in the season and for the following 2-3 years are
necessary to determine if all root stock has been eradicated.
Older, woody plants that have succeeded in climbing nearby trees should be cut at the base. Then,
cut the climbing vines up as high as you can reach, but leave the remaining vines that have climbed
into the tree canopy in place, as pulling them down can damage the tree. Disperse the cut vines in
the adjacent undergrowth for decomposition. The root stock will re-sprout, often in the same season, if
cut before late summer/early fall. If cut in the fall, they will re-sprout the following season. Repeat visits
are necessary to continue cutting back the new growth and eventually depriving the main root stock
of any remaining ability to regenerate.
