TREES ARE OUR BEST FRIENDS. THEY PLAY A
VERY IMPORTANT ROLE IN OUR LIFE. WE CAN NOT LIVE WITHOUT THEM. THEY GIVE US
TIMBER, PAPER AND FIREWOOD.
TIMBER IS USED IN MAKING HOUSES, TRAIN
COMPARTMENTS, BIG BOXES, TOOLS ETC. WITHOUT PAPER LIFE MAY BE DIFFICULT FOR US.
PAPER IS NECESSARY FOR STUDY AND WRITING. PEOPLE IN VILLAGES USE FIREWOOD TO
COOK MEALS. THEY USE WOOD TO BUILD HOUSES, HUTS, CARTS AND AGRICULTURE TOOLS.
TREES ALSO GIVE US FOOD, GUM AND
MEDICINE. THEY ALSO ADD TO THE BEAUTY OF LIFE. GARDENS CAN NOT BE CHARMING
WITHOUT THEM. WE NEED THEM FOR OXYGEN AND GOOD HEALTH.
TREES ALSO HELP TO CONTROL POLLUTION:
THEY ABSORB CARBON DIOXIDE. THEY IMPROVE OUR ENVIRONMENT. THEY CAUSE RAINFALL
AND PROTECT WATER RESOURCES UNDER THE GROUND. THEY PREVENT FLOODS AND DROUGHTS.
THEREFORE, WE SHOULD TRY OUR BEST TO
GROW MORE TREES. GOVT. AND SOCIAL WELFARE SOCIETIES SHOULD START A MOVEMENT.
THERE SHOULD BE AWARDS FOR THOSE PERSONS WHO GROW MORE TREES.
TREES COMBAT CLIMATE CHANGE
EXCESS CARBON DIOXIDE (CO2) CAUSED BY
MANY FACTORS IS A BUILDING UP IN OUR ATMOSPHERE AND CONTRIBUTING TO CLIMATE
CHANGE. TREES ABSORB CO2, REMOVING AND STORING THE CARBON WHILE RELEASING THE
OXYGEN BACK INTO THE AIR. IN ONE YEAR, AN ACRE OF MATURE TREES ABSORBS THE
AMOUNT OF CO2 PRODUCED WHEN YOU DRIVE YOUR CAR 26,000 MILES.
TREES CLEAN THE AIR
TREES ABSORB ODORS AND POLLUTANT
GASES (NITROGEN OXIDES, AMMONIA, SULFUR DIOXIDE AND OZONE) AND FILTER
PARTICULATES OUT OF THE AIR BY TRAPPING THEM ON THEIR LEAVES AND BARK.
TREES PROVIDE OXYGEN
IN ONE YEAR AN ACRE OF MATURE TREES
CAN PROVIDE ENOUGH OXYGEN FOR 18 PEOPLE.
TREES COOL THE STREETS AND THE CITY
AVERAGE TEMPERATURES IN LOS ANGELES
HAVE RISEN 6°F IN THE LAST 50 YEARS AS TREE COVERAGE HAS DECLINED AND THE
NUMBER OF HEAT-ABSORBING ROADS AND BUILDINGS HAS INCREASED.
TREES COOL THE CITY BY UP TO 10°F, BY SHADING OUR HOMES AND STREETS, BREAKING UP URBAN “HEAT ISLANDS” AND RELEASING WATER VAPOR INTO THE AIR THROUGH THEIR LEAVES.
TREES COOL THE CITY BY UP TO 10°F, BY SHADING OUR HOMES AND STREETS, BREAKING UP URBAN “HEAT ISLANDS” AND RELEASING WATER VAPOR INTO THE AIR THROUGH THEIR LEAVES.
TREES CONSERVE ENERGY
THREE TREES PLACED STRATEGICALLY
AROUND A SINGLE-FAMILY HOME CAN CUT SUMMER AIR CONDITIONING NEEDS BY UP TO 50 PERCENT.
BY REDUCING THE ENERGY DEMAND FOR COOLING OUR HOUSES, WE REDUCE CARBON DIOXIDE
AND OTHER POLLUTION EMISSIONS FROM POWER PLANTS.
TREES SAVE WATER
SHADE FROM TREES SLOWS WATER
EVAPORATION FROM THIRSTY LAWNS. MOST NEWLY PLANTED TREES NEED ONLY FIFTEEN GALLONS
OF WATER A WEEK. AS TREES TRANSPIRE, THEY INCREASE ATMOSPHERIC MOISTURE.
TREES HELP PREVENT WATER POLLUTION
TREES REDUCE RUNOFF BY BREAKING
RAINFALL THUS ALLOWING THE WATER TO FLOW DOWN THE TRUNK AND INTO THE EARTH
BELOW THE TREE. THIS PREVENTS STORMWATER FROM CARRYING POLLUTANTS TO THE OCEAN.
WHEN MULCHED, TREES ACT LIKE A SPONGE THAT FILTERS THIS WATER NATURALLY AND
USES IT TO RECHARGE GROUNDWATER SUPPLIES.
TREES HELP PREVENT SOIL EROSION
ON HILLSIDES OR STREAM SLOPES, TREES
SLOW RUNOFF AND HOLD SOIL IN PLACE.
TREES SHIELD CHILDREN FROM ULTRA-VIOLET
RAYS
SKIN CANCER IS THE MOST COMMON FORM
OF CANCER IN THE UNITED STATES. TREES REDUCE UV-B EXPOSURE BY ABOUT 50 PERCENT,
THUS PROVIDING PROTECTION TO CHILDREN ON SCHOOL CAMPUSES AND PLAYGROUNDS -
WHERE CHILDREN SPEND HOURS OUTDOORS.
TREES PROVIDE FOOD
AN APPLE TREE CAN YIELD UP TO 15-20
BUSHELS OF FRUIT PER YEAR AND CAN BE PLANTED ON THE TINIEST URBAN LOT. ASIDE
FROM FRUIT FOR HUMANS, TREES PROVIDE FOOD FOR BIRDS AND WILDLIFE.
TREES HEAL
STUDIES HAVE SHOWN THAT PATIENTS WITH
VIEWS OF TREES OUT THEIR WINDOWS HEAL FASTER AND WITH LESS COMPLICATIONS.
CHILDREN WITH ADHD SHOW FEWER SYMPTOMS WHEN THEY HAVE ACCESS TO NATURE.
EXPOSURE TO TREES AND NATURE AIDS CONCENTRATION BY REDUCING MENTAL FATIGUE.
TREES REDUCE VIOLENCE
NEIGHBORHOODS AND HOMES THAT ARE
BARREN HAVE SHOWN TO HAVE A GREATER INCIDENCE OF VIOLENCE IN AND OUT OF THE
HOME THAN THEIR GREENER COUNTERPARTS. TREES AND LANDSCAPING HELP TO REDUCE THE
LEVEL OF FEAR.
TREES MARK THE SEASONS
IS IT WINTER, SPRING, SUMMER OR FALL?
LOOK AT THE TREES.
TREES CREATE ECONOMIC OPPORTUNITIES
FRUIT HARVESTED FROM COMMUNITY
ORCHARDS CAN BE SOLD, THUS PROVIDING INCOME. SMALL BUSINESS OPPORTUNITIES IN
GREEN WASTE MANAGEMENT AND LANDSCAPING ARISE WHEN CITIES VALUE MULCHING AND ITS
WATER-SAVING QUALITIES. VOCATIONAL TRAINING FOR YOUTH INTERESTED IN GREEN JOBS
IS ALSO A GREAT WAY TO DEVELOP ECONOMIC OPPORTUNITIES FROM TREES.
TREES ARE TEACHERS AND PLAYMATES
WHETHER AS HOUSES FOR CHILDREN OR
CREATIVE AND SPIRITUAL INSPIRATION FOR ADULTS, TREES HAVE PROVIDED THE SPACE
FOR HUMAN RETREAT THROUGHOUT THE AGES.
TREES BRING DIVERSE GROUPS OF PEOPLE
TOGETHER
TREE PLANTINGS PROVIDE AN OPPORTUNITY
FOR COMMUNITY INVOLVEMENT AND EMPOWERMENT THAT IMPROVES THE QUALITY OF LIFE IN
OUR NEIGHBORHOODS. ALL CULTURES, AGES, AND GENDERS HAVE AN IMPORTANT ROLE TO
PLAY AT A TREE PLANTING OR TREE CARE EVENT.
TREES ADD UNITY
TREES AS LANDMARKS CAN GIVE A
NEIGHBORHOOD A NEW IDENTITY AND ENCOURAGE CIVIC PRIDE.
TREES PROVIDE A CANOPY AND HABITAT FOR
WILDLIFE
SYCAMORE AND OAK ARE AMONG THE MANY
URBAN SPECIES THAT PROVIDE EXCELLENT URBAN HOMES FOR BIRDS, BEES, POSSUMS AND
SQUIRRELS.
TREES BLOCK THINGS
TREES CAN MASK CONCRETE WALLS OR
PARKING LOTS, AND UNSIGHTLY VIEWS. THEY MUFFLE SOUND FROM NEARBY STREETS AND
FREEWAYS, AND CREATE AN EYE-SOOTHING CANOPY OF GREEN. TREES ABSORB DUST AND
WIND AND REDUCE GLARE.
TREES PROVIDE WOOD
IN SUBURBAN AND RURAL AREAS, TREES
CAN BE SELECTIVELY HARVESTED FOR FUEL AND CRAFT WOOD.
TREES INCREASE PROPERTY VALUES
THE BEAUTY OF A WELL-PLANTED PROPERTY
AND ITS SURROUNDING STREET AND NEIGHBORHOOD CAN RAISE PROPERTY VALUES BY AS
MUCH AS 15 PERCENT.
TREES INCREASE BUSINESS TRAFFIC
STUDIES SHOW THAT THE MORE TREES AND
LANDSCAPING A BUSINESS DISTRICT HAS, THE MORE BUSINESS WILL FLOW IN. A
TREE-LINED STREET WILL ALSO SLOW TRAFFIC – ENOUGH TO ALLOW THE DRIVERS TO LOOK
AT THE STORE FRONTS INSTEAD OF WHIZZING BY.
10 REASONS LIVING TREES ARE VALUABLE
TREES SPARED FROM HARVEST HAVE GREAT VALUE
THE TREES AROUND US ARE EXTREMELY IMPORTANT AND HAVE ALWAYS BEEN
NECESSARY FOR IMPROVING THE HUMAN CONDITION - BOTH DURING ITS LIFE AND AFTER
HARVEST. IT IS NOT A STRETCH TO BELIEVE THAT WITHOUT TREES WE HUMANS WOULD NOT
EXIST ON THIS BEAUTIFUL PLANET. IN FACT, SOME CLAIM CAN BE MADE THAT OUR
MOTHER'S AND FATHER'S ANCESTORS CLIMBED TREES - ANOTHER DEBATE FOR ANOTHER
SITE.
SO, TREES
ARE ESSENTIAL TO LIFE AS WE KNOW IT AND ARE THE GROUND TROOPS MAKING UP AN
ENVIRONMENTAL FRONTLINE. OUR EXISTING FORESTS AND THE TREES WE PLANT WORK IN
TANDEM TO MAKE A BETTER WORLD. BUT I DARE SAY THAT TREES ARE NECESSARY TO
HARVEST IN A PRACTICALLY PLANNED AND SUSTAINABLE WAY USING THE MULTIPLE-USE CONCEPT.
AT THE VERY
BEGINNING OF OUR HUMAN EXPERIENCE, TREES WERE CONSIDERED SACRED AND
HONORABLE: OAKS WERE WORSHIPED BY THE EUROPEAN
DRUIDS, REDWOODS A PART OF AMERICAN INDIAN
RITUAL, BAOBABS A PART OF AFRICAN TRIBAL LIFE, TO THE CHINESE THE GINKGO LINK AND MONKEY PUZZLES TO THE
CHILEAN PEHUENCHE. ROMANS AND SCHOLARS DURING THE MIDDLE AGES VENERATED TREES
IN THEIR LITERATURE.
THE MODERN
HUMAN COMMUNITY HAS OTHER, MORE PRACTICAL REASONS TO ADMIRE AND HONOR TREES.
HERE IS A SHORT LIST OF REASONS TREES ARE NECESSARY FOR IMPROVING OUR WORLDLY
CONDITION.
FALL TREES IN LANDSCAPE.
1.
TREES PRODUCE OXYGEN
LET'S FACE
IT, WE COULD NOT EXIST AS WE DO IF THERE WERE NO TREES. A MATURE LEAFY TREEPRODUCES AS MUCH OXYGEN IN A SEASON AS 10
PEOPLE INHALE IN A YEAR. WHAT MANY PEOPLE DON'T REALIZE IS THE FOREST ALSO ACTS
AS A GIANT FILTER THAT CLEANS THE AIR WE BREATH.
TREES AND BRIDGE, ARBOR DAY FARM.
2.
TREES CLEAN THE SOIL
THE
TERM PHYTOREMEDIATION IS A FANCY WORD FOR THE
ABSORPTION OF DANGEROUS CHEMICALS AND OTHER POLLUTANTS THAT HAVE ENTERED THE
SOIL. TREES CAN EITHER STORE HARMFUL POLLUTANTS OR ACTUALLY CHANGE THE
POLLUTANT INTO LESS HARMFUL FORMS. TREES FILTER SEWAGE AND FARM CHEMICALS,
REDUCE THE EFFECTS OF ANIMAL WASTES, CLEAN ROADSIDE SPILLS AND CLEAN WATER
RUNOFF INTO STREAMS.
BURR OAK, ARBOR DAY FARM.
3.
TREES CONTROL NOISE POLLUTION
TREES MUFFLE
URBAN NOISE ALMOST AS EFFECTIVELY AS STONE WALLS. TREES, PLANTED AT STRATEGIC
POINTS IN A NEIGHBORHOOD OR AROUND YOUR HOUSE, CAN ABATE MAJOR NOISES FROM
FREEWAYS AND AIRPORTS.
BLUE SPRUCE, ARBOR DAY FARM.
4.
TREES SLOW STORM WATER RUNOFF
FLASH
FLOODING CAN BE DRAMATICALLY REDUCED BY A FOREST OR BY PLANTING TREES. ONE COLORADO BLUE SPRUCE, EITHER PLANTED OR
GROWING WILD, CAN INTERCEPT MORE THAN 1000 GALLONS OF WATER ANNUALLY WHEN FULLY
GROWN. UNDERGROUND WATER-HOLDING AQUIFERS ARE RECHARGED WITH THIS SLOWING DOWN
OF WATER RUNOFF.
A SALVAGEABLE WALNUT TREE.
5.
TREES ARE CARBON SINKS
TO PRODUCE
ITS FOOD, A TREE ABSORBS AND LOCKS AWAY CARBON DIOXIDE IN THE WOOD, ROOTS AND
LEAVES. CARBON DIOXIDE IS AGLOBAL WARMING SUSPECT. A FOREST IS A CARBON STORAGE AREA OR A
"SINK" THAT CAN LOCK UP AS MUCH CARBON AS IT PRODUCES. THIS
LOCKING-UP PROCESS "STORES" CARBON AS WOOD AND NOT AS AN AVAILABLE
"GREENHOUSE" GAS.
WHITE ASH, ARBOR DAY LIED CENTER.
6. TREES
CLEAN THE AIR
TREES HELP
CLEANSE THE AIR BY INTERCEPTING AIRBORNE PARTICLES, REDUCING HEAT, AND
ABSORBING SUCH POLLUTANTS AS CARBON MONOXIDE, SULFUR DIOXIDE, AND NITROGEN
DIOXIDE. TREES REMOVE THIS AIR POLLUTION BY LOWERING AIR
TEMPERATURE, THROUGH RESPIRATION, AND BY RETAINING PARTICULATES.

7.
TREES SHADE AND COOL
SHADE
RESULTING IN COOLING IS WHAT A TREE IS BEST KNOWN FOR. SHADE FROM TREES REDUCES
THE NEED FOR AIR CONDITIONING IN SUMMER. IN WINTER, TREES BREAK THE FORCE OF
WINTER WINDS, LOWERING HEATING COSTS. STUDIES HAVE SHOWN THAT PARTS OF CITIES
WITHOUT COOLING SHADE FROM TREES CAN LITERALLY BE "HEAT ISLANDS" WITH
TEMPERATURES AS MUCH AS 12 DEGREES FAHRENHEIT HIGHER THAN SURROUNDING AREAS.

TREES ACT AS WINDBREAKS
DURING WINDY
AND COLD SEASONS, TREES LOCATED ON THE WINDWARD SIDE ACT AS WINDBREAKS. A
WINDBREAK CAN LOWER HOME HEATING BILLS UP TO 30% AND HAVE A SIGNIFICANT EFFECT
ON REDUCING SNOW DRIFTS. A REDUCTION IN WIND CAN ALSO REDUCE THE DRYING EFFECT
ON SOIL AND VEGETATION BEHIND THE WINDBREAK AND HELP KEEP PRECIOUS TOPSOIL IN PLACE.
BALDCYPRESS, OKEEFENOKEE
9.
TREES FIGHT SOIL EROSION
EROSION
CONTROL HAS ALWAYS STARTED WITH TREE AND GRASS PLANTING PROJECTS. TREE ROOTS BIND THE SOIL AND THEIR LEAVES
BREAK THE FORCE OF WIND AND RAIN ON SOIL. TREES FIGHT SOIL EROSION, CONSERVE RAINWATER AND REDUCE
WATER RUNOFF AND SEDIMENT DEPOSIT AFTER STORMS.
IN BOTANY, A TREE IS
A PERENNIAL PLANT WITH AN ELONGATED STEM, OR TRUNK, SUPPORTING BRANCHES AND LEAVES IN MOST SPECIES. IN SOME
USAGES, THE DEFINITION OF A TREE MAY BE NARROWER, INCLUDING ONLY WOODY PLANTS WITH SECONDARY GROWTH, PLANTS THAT ARE
USABLE AS LUMBER OR PLANTS ABOVE A SPECIFIED
HEIGHT. TREES ARE NOT A TAXONOMIC GROUP BUT INCLUDE A VARIETY OF PLANT SPECIES
THAT HAVE INDEPENDENTLY EVOLVED A WOODY TRUNK AND BRANCHES AS A WAY TO TOWER
ABOVE OTHER PLANTS TO COMPETE FOR SUNLIGHT. IN LOOSER SENSES, THE TALLER PALMS, THE TREE FERNS, BANANAS AND BAMBOOSARE ALSO TREES. TREES TEND TO BE LONG-LIVED, SOME
REACHING SEVERAL THOUSAND YEARS OLD. THE TALLEST KNOWN TREE, A COAST
REDWOOD NAMED HYPERION, STANDS 115.6 M (379 FT) HIGH. TREES
HAVE BEEN IN EXISTENCE FOR 370 MILLION YEARS. IT IS ESTIMATED THAT THERE ARE
JUST OVER 3 TRILLION MATURE TREES IN THE WORLD.
A TREE TYPICALLY HAS MANY SECONDARY BRANCHES
SUPPORTED CLEAR OF THE GROUND BY THE TRUNK. THIS TRUNK TYPICALLY CONTAINS WOODY TISSUE FOR STRENGTH, AND VASCULAR
TISSUE TO CARRY
MATERIALS FROM ONE PART OF THE TREE TO ANOTHER. FOR MOST TREES IT IS SURROUNDED
BY A LAYER OF BARK WHICH SERVES AS A PROTECTIVE BARRIER.
BELOW THE GROUND, THE ROOTS BRANCH AND SPREAD OUT WIDELY; THEY SERVE TO ANCHOR
THE TREE AND EXTRACT MOISTURE AND NUTRIENTS FROM THE SOIL. ABOVE GROUND, THE
BRANCHES DIVIDE INTO SMALLER BRANCHES AND SHOOTS. THE SHOOTS TYPICALLY BEAR
LEAVES, WHICH CAPTURE LIGHT ENERGY AND CONVERT IT INTO SUGARS BY PHOTOSYNTHESIS,
PROVIDING THE FOOD FOR THE TREE'S GROWTH AND DEVELOPMENT. FLOWERS AND FRUIT MAY
ALSO BE PRESENT, BUT SOME TREES, SUCH AS CONIFERS, INSTEAD HAVE POLLEN CONES
AND SEED CONES; OTHERS, SUCH AS TREE FERNS, PRODUCE SPORES INSTEAD.
TREES
PLAY A SIGNIFICANT ROLE IN REDUCING EROSION AND MODERATING THE CLIMATE. THEY
REMOVE CARBON
DIOXIDE FROM THE
ATMOSPHERE AND STORE LARGE QUANTITIES OF CARBON IN THEIR TISSUES. TREES AND FORESTS PROVIDE A HABITAT FOR MANY SPECIES OF ANIMALS AND
PLANTS. TROPICAL RAINFORESTS ARE ONE OF THE MOST BIODIVERSE HABITATS IN THE WORLD. TREES PROVIDE
SHADE AND SHELTER, TIMBER FOR CONSTRUCTION, FUEL FOR COOKING AND HEATING, AND
FRUIT FOR FOOD AS WELL AS HAVING MANY OTHER USES. IN PARTS OF THE WORLD,
FORESTS ARE SHRINKING AS TREES ARE CLEARED TO INCREASE THE AMOUNT OF LAND
AVAILABLE FOR AGRICULTURE. BECAUSE OF THEIR LONGEVITY AND USEFULNESS, TREES
HAVE ALWAYS BEEN REVERED AND THEY PLAY A ROLE IN MANY OF THE WORLD'S MYTHOLOGIES.
ALTHOUGH "TREE" IS A
TERM OF COMMON PARLANCE, THERE IS NO UNIVERSALLY RECOGNISED PRECISE DEFINITION
OF WHAT A TREE IS, EITHER BOTANICALLY OR IN COMMON LANGUAGE.IN ITS BROADEST
SENSE, A TREE IS ANY PLANT WITH THE GENERAL FORM OF AN ELONGATED STEM, OR
TRUNK, WHICH SUPPORTS THE PHOTOSYNTHETIC LEAVES OR BRANCHES AT SOME DISTANCE
ABOVE THE GROUND.TREES ARE ALSO TYPICALLY DEFINED BY HEIGHT, WITH SMALLER PLANTS FROM 0.5 TO
10 M (1.6 TO 32.8 FT) BEING CALLED SHRUBS, SO THE MINIMUM HEIGHT OF A TREE IS
ONLY LOOSELY DEFINED.LARGE HERBACEOUS PLANTS SUCH AS PAPAYA ANDBANANAS ARE TREES IN THIS BROAD SENSE.
TREES ARE BEAUTIFUL AND
USEFUL GIFTS OF NATURE. TREES ARE GREAT FRIENDS OF MEN. TREES GIVE US FLOWERS,
FRUITS, TIMBER, BAMBOO, FUELS, ETC. WE CAN REST UNDER THE COOL SHADE OF A TREE.
WE GET WOOD FROM THE TREES TO MAKE FURNITURE, DOORS, WINDOWS, ETC.
TREES ARE ALSO A GREAT SOURCE OF MATERIALS FOR
PAPER, RUBBER, GUMS, HERBS AND MEDICINE PLANTS. FOREST BRINGS CLOUDS AND CAUSE
RAINFALL. TREES PREVENT SOIL EROSION. THEY PROTECT US FROM SEVERE WEATHER.
IMPORTANCE OF TREES: TREES ARE A PART
AND PARCEL OF EARTHLY LIFE. ALL LIFE DIRECTLY OR INDIRECTLY OWES ITS EXISTENCE
TO THEM.
TREES RELEASE OXYGEN WHICH WE NEED FOR OUR LIFE.
THEY ALSO ABSORB THE CARBON-DIOXIDE.
TREES ARE THE NATURAL HABITAT OF MANY ANIMALS AND
BIRDS.
TREES HELP MAKE THE LAND FERTILE. WE GET GOOD CROPS
OUT OF FERTILE LAND.
THEY ARE THE SOURCES OF THE FRUITS AND FLOWERS.
THEY OFFER US COOL SHADE DURING SUMMER.
DURING RAINY SEASON, WE TAKE SHELTER UNDER THE
TREES.
TREES AND PLANTS ARE THE SOURCES OF
MANY SUPPLY LIFE-SAVING DRUGS.
THEY PREVENT LAND EROSION AND GUARD US AGAINST
POLLUTION. THUS, TREES KEEP UP THE ECOLOGICAL BALANCE.
TREES PROTECT US FROM INCLEMENT WIND ALSO.
CONCLUSION: THUS, TREES PLAY
AN IMPORTANT ROLE IN OUR LIFE. FELLING OF TREES DISTURBS THE ECO-SYSTEM. WE
SHOULD PRESERVE TREES AND PLANTS WITH GREAT CARE.
PROTECTING TREES DURING CONSTRUCTION &
BUILDING AROUND TREES
AS ASPIRING HOMESTEADERS CONTEMPLATE A WOODED LOT,
THEY USUALLY IMAGINE THEIR DREAM HOME SURROUNDED BY HEALTHY, VIGOROUS TREES
THAT SHADE THE SUMMER SUN AND WHISPER WITH EVERY BREEZE. AFTER THE HOME IS
BUILT, HOWEVER, THE TREES THAT MADE THE LOCATION DESIRABLE OFTEN ARE EITHER
GONE OR DYING, THE VICTIMS OF DAMAGING CONSTRUCTION WORK.
THE CONFLICT BETWEEN LAND DEVELOPMENT AND TREE
PROTECTION SEEMS TO BE A LOSING BATTLE. OFTEN TIMES, A BUILDING SITE HAS BEEN
CHOSEN BECAUSE OF THE PRESENCE OF MATURE TREES. THESE TREES, HOWEVER, HAVE
DIFFICULTY SURVIVING THE CONSTRUCTION PROCESS. ALTHOUGH MOST DEVELOPERS WOULD
PREFER TO SAVE TREES ON A PROPERTY, THEY ARE OFTEN DISCOURAGED BY PAST FAILURES
OR REGULATIONS THAT FORCE THEM TO REMOVE TREES TO LOCATE UTILITIES.
COMMUNICATION AND COOPERATION AMONG ALL PARTICIPANTS INVOLVED IN THE BUILDING
PROCESS (LANDOWNER, CONTRACTORS, ARCHITECT, LANDSCAPE ARCHITECT, ARBORIST,
ETC.) IS ESSENTIAL TO ENSURE A SUCCESSFUL TREE-PROTECTION PLAN.
NO MATTER HOW GOOD OUR INTENTIONS, ANY CONSTRUCTION
WORK NEAR TREES WILL HAVE SOME IMPACT ON THEM, BECAUSE OF THE CLOSE
RELATIONSHIP BETWEEN A TREE AND THE SOIL SURROUNDING IT. TREES ARE MUCH MORE
THAN THE VISIBLE TRUNK, BRANCHES AND LEAVES.
HOW TREES ARE HARMED BY CONSTRUCTION
TREES CAN BE HARMED BY CONSTRUCTION WORK IN SEVERAL
WAYS. ANY BREAK OR TEAR IN A TREE'S BARK DISRUPTS THE FLOW OF VITAL FLUIDS AND
EXPOSES WOOD TO INVASION BY DISEASE AND DECAY MICROORGANISMS, WHICH THE TREE
MUST THEN EXPEND ENERGY TO DEAL WITH. A TRUNK WOUND DOES NOT ALWAYS CAUSE
CORRESPONDING LOSS OF BRANCHES OR FOLIAGE, SO THE CONSEQUENCES MAY NOT BE FULLY
APPARENT. BUT A LARGE WOUND IN THE TRUNK OF A TREE IS SERIOUS-IT CANNOT BE
REPAIRED AND WILL ALMOST CERTAINLY RESULT IN FUTURE DECAY AND LOSS OF STEM
STRENGTH.
JUST AS SERIOUS, ALTHOUGH NOT AS VISIBLE, IS DAMAGE
TO THE ROOT SYSTEM. ROOTS CAN BE SEVERED BY EXCAVATION OR SMOTHERED BY EARTH
FILL OR COMPACTED SOIL.
COMPACTION, THE LOSS OF TINY AIR SPACES WITHIN THE
SOIL FROM FOOT OR VEHICLE TRAFFIC, IS ESPECIALLY INSIDIOUS. NOT ONLY WILL
EXISTING TREE ROOTS BE AFFECTED, BUT FUTURE ROOT GROWTH ALSO WILL BE IMPAIRED.
SYMPTOMS OF ROOT DAMAGE FROM COMPACTION INCLUDE SLOW GROWTH AND BRANCH DIEBACK
IN THE TOP OF THE TREE. SOIL COMPACTION MAY KILL TREES, ALTHOUGH NO OTHER
DAMAGE OCCURS. NEW TREES, SHRUBS OR GROUND COVERS PLANTED IN THE DENSE SOIL
ALSO WILL SUFFER.
INJURIES ARE CUMULATIVE. CONSTRUCTION WORK WILL COMPOUND PROBLEMS TREES
MAY HAVE RECEIVED FROM EARLIER DROUGHT, INSECTS OR OTHER NATURAL CAUSES. THIS
MEANS
THAT TREES IN POOR CONDITION BEFORE CONSTRUCTION
WORK ARE NOT AS LIKELY TO TOLERATE FURTHER DAMAGE. IT ALSO MEANS THAT TREES
THAT DO NOT SUCCUMB TO CONSTRUCTION DISTURBANCE MAY BE LEFT WEAKENED AFTER THE
WORK IS FINISHED.
HOW TO PROTECT TREES DURING CONSTRUCTION
ARE WE JUST LUCKY IF TREES SURVIVE CONSTRUCTION?
NOT AT ALL. WE CAN GREATLY INCREASE THE CHANCES OF KEEPING TREES HEALTHY BY
USING THESE STRATEGIES:
SURVEY THE ENTIRE CONSTRUCTION SITE WELL BEFORE
WORK BEGINS TO DETERMINE WHERE TREES ARE AND WHAT CONDITION THEY ARE IN. IT IS
BEST TO PLOT ALL TREES ON A SCALED DRAWING, BUT THIS ALSO CAN BE DONE ON THE
GROUND, ESPECIALLY FOR SMALL CONSTRUCTION PROJECTS. HEALTHY, VIGOROUS TREES
WITH SOLID STEMS AND A FULL COMPLEMENT OF LIVE BRANCHES ARE THE BEST CANDIDATES
FOR SAVING. LARGE, OLD TREES MAY NOT TOLERATE MUCH DISTURBANCE. DON'T OVERLOOK
SMALLER, UNDER-STORY TREES, SUCH AS DOGWOOD, REDBUD, SERVICEBERRY AND IRONWOOD.
IF YOU ARE WORKING WITH BUILDERS, INFORM THEM OF YOUR DESIRE TO SAVE TREES.
DEVELOP A CONSTRUCTION PLAN THAT BLENDS THE
BUILDINGS WITH THE TREES ON THE SITE. THIS IS THE TIME TO DECIDE WHICH TREES
WILL BE REMOVED AND WHICH WILL REMAIN. CONSIDER ALTERNATE LOCATIONS FOR
FOOTINGS, WALKS, DRIVES AND CHANGES IN THE GROUND LINE TO SAVE THE BEST TREES.
KEEP IN MIND THAT IT MAY BE NECESSARY TO REMOVE
SOME GOOD TREES SIMPLY BECAUSE THERE IS NOT SUFFICIENT SPACE FOR THEM. IT IS
MUCH EASIER TO MAKE THESE CHOICES BEFORE THE CONSTRUCTION WORK BEGINS. THE
PLAN CAN BE DRAFTED ON A LAYER THAT OVERLAYS THE SURVEY PLAN, OR MARK THE
GROUND WITH STAKES OR FLAGS. REMEMBER THAT YOU NEED TO KEEP A RELATIVELY LARGE
UNDISTURBED AREA AROUND EACH TREE TO HELP PROTECT IT. THE LARGER THE TREE, THE
LARGER THE AREA NEEDED SURROUNDING IT.
ESTABLISH TREE PROTECTION ZONES AROUND INDIVIDUAL
TREES OR GROUPS OF TREES TO BE SAVED. EXCLUDE ANY TYPE OF CONSTRUCTION
DISTURBANCE, INCLUDING GRADE CHANGES, VEHICLE PARKING OR STORAGE OF MATERIALS
AROUND PROTECTED TREES. SET STEEL FENCE POSTS WITH FLEXIBLE, SNOW-FENCE-TYPE
FABRIC AROUND THE PERIMETER OF EACH PROTECTION ZONE.
ROUTE TRENCHES AS FAR AWAY FROM TREES AS POSSIBLE.
UTILITIES THAT MAY REQUIRE TRENCHING INCLUDE SANITARY SEWER, WATER, GAS,
ELECTRICITY AND TELEPHONE OR TELEVISION CABLE. SOME UTILITIES MAY BE ADVANTAGEOUSLY
PLACED IN THE SAME TRENCH. PLACEMENT OF SOME UTILITIES IS FLEXIBLE, WHILE
OTHERS ARE NOT. IF A TRENCH CANNOT BE PLACED BY THE BUILDER TO AVOID COMING
CLOSE TO A VALUABLE TREE, CONSIDER GOING UNDER IT. DIG THE TRENCH DIRECTLY UP
TO A TREE TRUNK ON BOTH SIDES. THEN BORE OR FORCE A TUBE OR LINE THROUGH THE
SOIL BELOW THE TREE. REROUTING OR TUNNELING FOR UTILITIES MAY ADD TO THE COST
OF THE PROJECT, BUT ALSO WILL INCREASE THE CHANCES OF SAVING TREES.
IF BRANCHES OR ROOTS MUST BE SEVERED, CUT THEM WITH
CARE. GENERALLY, REMOVE ENTIRE LIMBS OR BRANCHES AT THEIR ORIGIN. USE THE 3-CUT
METHOD TO AVOID STRIPPING BARK BELOW THE LIMB AND TO PROMOTE PROPER WOUND
CLOSURE. ROOTS SHOULD BE CLEANLY CUT WITH A SAW TO MAXIMIZE ROOT REGENERATION
AND MINIMIZE CHANCES FOR DECAY. DO NOT LEAVE RAGGED ENDS. DIG CAREFULLY AROUND
LARGE ROOTS AND ALLOW THEM TO PASS THROUGH A TRENCH. PLACE UTILITY PIPES OR
LINES BELOW THE ROOTS. BACKFILL TRENCHES WITH LOOSE SOIL PLACED ON TOP.
BECAUSE LEAVES MANUFACTURE FOOD FOR A TREE, REMOVAL
OF MORE THAN ONE FOURTH OF THE LIVE BRANCHES THREATENS A TREE. WEAK TREES, OR
TREES WITH ROOT DAMAGE, FOR EXAMPLE, MAY TOLERATE LESS. REMOVING DEAD LIMBS
WILL NOT HURT A TREE.
PRUNING YOUR TREES BEFORE CONSTRUCTION COULD BE THE
DIFFERENCE BETWEEN SAVING THAT BEAUTY AND LOSING IT! THESE RECOMMENDED GUIDES
WILL GIVE YOU THE INSTRUCTIONS YOU NEED TO KEEP THOSE TREES HEALTHY!
USE WOOD CHIPS AS A PROTECTIVE BLANKET OVER THE
GROUND. A LAYER 4 INCHES OR MORE DEEP WILL HELP PREVENT SOIL COMPACTION,
ESPECIALLY WHERE CONSTRUCTION WORK NEAR TREES CANNOT BE AVOIDED. CHIPS HELP
PROTECT SOILS ANYWHERE ON THE SITE WHERE NEW TREES, SHRUBS OR TURF WILL BE
PLANTED. REPLENISH CHIPS AS THEY DETERIORATE OR WEAR THIN.
AVOID POST-CONSTRUCTION ACTIVITIES WHICH COULD
FURTHER STRESS WEAKENED TREES. REFRAIN FROM ADDING TOPSOIL AROUND TREES,
INSTALLING UNDERGROUND IRRIGATION PIPES OR USING HERBICIDES WITHIN TREE ROOTING
AREAS. DO NOT PRUNE TREES HEAVILY, UNTIL NORMAL GROWTH RATE RETURNS.
PLAN FOR NEW TREES, SHRUBS, AND GROUND COVERS,
WHICH ARE COMPATIBLE WITH A WOODED ENVIRONMENT. PLANT SHADE TOLERANT SHRUBS AND
SMALL TREES AROUND SAVED TREES TO MAINTAIN A WOODED APPEARANCE AND HELP
PRESERVE THE ORIGINAL ROOT ENVIRONMENT. RETAIN AND EXPAND THE NATURAL FOREST
FLOOR WITH BARK MULCH. PLANT TURF GRASSES IN MORE OPEN, SUNNY AREAS WHERE THEY
WILL GROW BETTER AND COMPETE LESS WITH TREE ROOTS.
BUILDING HOMES OR OTHER BUILDINGS ON WOODED SITES
REQUIRES TAKING PRECAUTIONS TO PRESERVE THE TREES. CONSIDER TREE NEEDS BEFORE
CONSTRUCTION BEGINS. FIND THE BEST TREES AND CONCENTRATE ON SAVING THEM. YOU
MAY WISH TO PROTECT SMALL TREES THAT HAVE THE POTENTIAL TO GROW INTO SHADE
TREES.
DURING CONSTRUCTION, PROTECT AS MUCH UNDISTURBED
AREA AROUND EACH TREE AS POSSIBLE, REMEMBERING TO TAKE INTO ACCOUNT BOTH THE
VISIBLE AND THE FRAGILE UNDERGROUND PARTS OF THE TREES. FINALLY, CONTINUE TO
CARE FOR YOUR TREES AFTER CONSTRUCTION IS FINISHED. YOUR EFFORTS ON BEHALF OF
THE TREES WILL MAKE YOUR DREAM HOME IN A WOODSY SETTING A REALITY.
NO TWO TREES WILL REACT THE SAME TO DISTURBANCE BECAUSE OF DIFFERENCES
IN SOIL TYPE, SPECIES, AGE AND CONDITION. HEALTHY TREES GENERALLY CAN TOLERATE
LIMITED INJURY IF THEY HAVE A GOOD GROWING ENVIRONMENT FOR RECUPERATION. THE
MORE SEVERE THE DAMAGE AND ADVERSE THE GROWING CONDITIONS, THE HIGHER THE RISK.
