AN INDEPENDENT PROGRAM OF TOWER HILL BOTANIC GARDEN
On Friday, May 19th, WTI planted 20 trees with volunteers from TD Bank, Claremont Academy, and the Worcester Boys and Girls Club. This was the culmination of our TD Green Streets Grant, awarded in 2016. The planting this May was the last step in a multitiered project. We are so grateful to TD Green Streets for including us among other amazing projects in urban forests around the country from Rhode Island to Florida.
In addition to this planting our project included an education program at the Boys and Girls Club where WTI spoke to youth twice a week for four weeks, teaching them about topics such as the value of the urban forest, forest pests, how to check if a tree is healthy, and planting a tree. We taught a similar curriculum over the course of a year with students at Claremont Academy, a program which we continued this year as the Claremont Green Team.
The 20 trees were a mix of Tupelos, Hop Hornbeams, Lindens, and Ginkgo trees planted on the perimeter of Clark University’s new practice fields. The fields are located right next to the Boys and Girls Club on Tainter Street. There is also a pedestrian path connecting the two segments of Tainter Street, connecting the neighborhoods on either side of the fields. The fields are fenced off from the public but the Boys and Girls Club will have open access to the fields for their club activities.
We know it is important to engage people young and old with the environment in their own backyard and we are excited that through this project we were able to grow that environment for residents of Main South. Several of our projects this spring have focused on this neighborhood or other similarly under forested neighborhoods. We will keep working with the communities all around Worcester to ensure that all of our city is vibrant and verdant.

At this time of year it can be hard to slow down long enough to reflect on all of the things that have happened and then actually tell the story!
In the past month and a half we have hosted or led nearly 20 events from our Spring Fling to trainings and talks at Tower Hill, and our Arbor Day Celebration and other plantings. So far we have planted 50 trees this season with another 80 to go in the next two weeks! Plus we will be having a giveaway at the end of the month.
To say things have been busy would be putting it lightly, but today, with another tree to plant in the afternoon, I find myself with enough space to write a quick update.
If you haven’t been following our Instagram or Facebook pages you’ve missed out on some snapshots from our many events this spring. We’ve been in Green Hill Park at the World War I Memorial Grove planting trees, we’ve been to Kilby Street planting trees with the Main South CDC’s Main South Youth Corps. We planted fruit trees with the crew at Hector Reyes House and Youth Grow Farm with the Regional Environmental Council. We even participated in 3 Jane Jacobs in The Woo “Jane Walks”, the Community Health Improvement Plan (CHIP) Walk where we planted a tree and talked about the importance of trees to public health, the Pop Up Parklet in Downtown next to Dead Horse Hill where we contributed a tree to the landscaping, and the tour of Newton Hill and a segment of the East-West Trail which was co-led by our own Director, Ruth Seward. The other day we even got interviewed for a book being written about Worcester!
We owe a lot to our partners at the Massachusetts Department of Conservation and Recreation (DCR) and the USDA. Much of our work is supported by the Reforestation Program and the Asian Longhorned Beetle Eradication crews dedicated their Arbor Day this year to volunteering for us. We also want to thank the City of Worcester for letting us lead the charge on the Arbor Day Celebration and for their help with a delivery of wood chips for the newly planted trees last week in the Memorial Grove.
In addition to all of the planting we’ve been doing I mentioned that we had led or participated in several trainings/talks at Tower Hill. We’re most grateful to the Tower Hill team that has been embracing us as their own for the past year. We’re thrilled that we get to now lead talks for their members and the public at the Gardens. We talked about pest management for our first talk and tree pruning basics in our CUT IT OUT class. There will be a follow up to this course for flowering trees and shrubs on June 17th. You can register ahead for that event on our Upcoming Events page. We also got to attend and became audience participants in the discussion of the book Urban Forests with the author, Jill Jonnes. Her talk was so good that we want to give you another chance to hear from her and are planning to have her visit again in the fall.
Last Wednesday we planted at the Francis Perkins Branch of the Worcester Public Library, planting with some of the kids at their after school program and with DCR. This weekend we went back in Green Hill Park planting another 38 trees with the Massachusetts Sierra Club, members of the Green Hill Park Coalition, and students from Wachusett Regional High School. This Friday, May 19th, we’re planting 20 trees next to the Boys and Girl’s Club at the new Clark Athletic Fields with volunteers from TD Bank, the Boys and Girl’s Club, and Claremont Academy. We’re grateful for the TD Green Streets grant awarded to us for this project and to all of the partners who will be joining us to help with the planting.
And there’s more to come. Keep an eye out for our upcoming projects on the website and on our social media profiles. We appreciate hearing from you so let us know how we’re doing in the community with an email, a like, or by sharing our posts so more people can see what we’re up to.
Tree of the Week
Theme: Cold Weather Champions
Whitebark pine, also known as Pinus albicaulis, are found in high mountain landscapes in western North America and Canada. Grow in the western united states and canada areas such as sierra nevada, the cascade range, the pacific coast range and the rocky mountain. In these areas the whitebark pine are typically the highest elevation pine tree. They prefer cold windy, snowy, and moist climate. Temperatures around -5C (25F) in January are perfect for the trees development and growth, though they can withstand much harsher conditions.
Whitebark pine is one of a group of pines found in the same regions. They tend to be slow growing but long lived trees; depending on the conditions whitebark pines can live up to 250 years or more. Their height varies but in good conditions will grow between 40 and 60 feet. At the limit of their range this species stays low to the ground and only grows to about 3 feet or less. Their needle shaped leaves grow in bundles of five, which is different from other members of the group such as lodgepole pine which have two needles per bundle. The needles, which are short and rigid, grow from 1 to 3 inches long with a green- yellow color. Another distinguishing set of features of whitebark pines are their cones. The Whitebark pine is monecious, producing both male and female flowers and cones on the same tree. Male cones are pinkish while the female cones are deep red and sometimes purple. Both cones remains on the tree for several years.
The seeds inside of the cone are essential to the animals that live in that area. Small mammals and birds such as nutcrackers, woodpeckers, finches, and other granivorous birds all depend on the seeds from this tree as part of their diet. Human also eat their seed, sometimes raw or roasted after collecting them during the fall season.
The Whitebark pine plays an important ecological role in the places where it grows. Because the tree can grow in harsh climates and poor and rocky mountainous soils the roots of whitebark pine stabilize that soil and protect the watershed at large. But there are environmental factors that have led to a decline in population of this tree. In some populations a fungal disease called white pine rust is killing these trees but a much more threatening pest is the mountain pine beetle which has ravages pines west of the Rocky Mountains. At the moment they are kept at bay by the harsh climates in the high peaks of the Rockies and northern Canada but if climatic changes continue this pest could break out to the east which would unleash yet more devastation on our nation’s forest.
Tree of the Week Theme: Cold Weather Champions!
This month’s theme is cold weather campions. Today we’re covering the Subalpine fir, a slender conifer found in the western United States and Canada. It is native to fairly high elevation, cool, moist sites from the southern Rockies to northwestern Canada, including Utah.
The vegetation zone that this tree grows in is named the Subalpine zone, which is the zone which transitions from denser forest to the tree line, geographic areas where weather conditions are too harsh for trees to grow. The subalpine fir is named for this zone. The Subalpine fir can endure temperatures as low as –58 degrees fahrenheit. As a result, they form extensive forests in the high, cold mountains throughout western North America. They also are tolerant of very wet conditions, including the swampy grounds near beaver ponds or other wetland areas. The tree has a very distinctive crown that is slender due to its short stiff branches. These trees look like minarets poking above the forest, growing up to 160 ft tall in good conditions.
The Subalpine fir cones mature in one growing season and the tree produces an abundance of cones each year near the tops of the tree. Male cones are in small clusters on underside of twig ends and are bluish. Female (seed) cones are about 3-½ inches long and dark purple when mature. They always grow on upper branches in an upward position on twigs. When these cones mature, the cone scales and seeds fall off leaving a woody spike-like cone on the twig. Like the cones of the other firs, they disintegrate on the tree, leaving a central spike.
The needles have blunt ends and are often notched at the tip. They are blue-green with a single white band on the top and two beneath. Needles all tend to turn upwards, but often a few stick out from the underside of the branch. The bark is gray, thin and smooth with resinous blisters that become shallowly furrowed on older trunks.
Throughout much of the Rocky Mountains, the subalpine fir assists in protecting watersheds and rehabilitating the landscape. Forests in which subalpine fir grows occupy the highest water yield areas in much of the West. They also provides habitat for various animals. Mule deer, elk, moose, woodland caribou, black bear, and grizzly bear often use subalpine fir habitats during the summer. Its seeds are eaten by several species of small mammals and birds.
The wood of subalpine fir is not ideal for use in outdoor projects since it decays fairly quickly which can only be offset using a large amount of preservatives. However it can be used for wall studs and because the wood pulp from the tree is used to make various wood products. Small trees are also extensively used for Christmas trees.
Native Americans used various parts of subalpine fir for numerous purposes. The crushed needles could be used for healing and cleaning on cuts or as a perfume. The sap was also used medicinally to clean wounds but also in tea as a remedy for a cold. Entire branches were also used as a home air freshener; who needs artificially scented candles when you can have the real deal?
Tree of the Week Theme: Cold Weather Champions!
Tamarack also known as Larch (Larix laricina), are unique trees in the landscape; they are deciduous conifers. Tamaracks usually live about 150 years. Their height varies but they can grow between 65’ and 150’ tall. The tamarack, prefers colder climates and can be found extensively throughout Canada and the northern United States but can also be found in the south on high mountain peaks. Despite the breadth of its range the tamarack is underutilized as a landscape tree. It in a perfect conical shape and it can grow as well as and be as beautiful as many of the imported species often used in its place.
The leaves on the Tamarack grow light green in the spring and stay on the tree through the summer in distinct clusters of 15-25 needles that look like crowns. In the fall, Tamarack’s three-sided leaves turn golden yellow and fall off of the tree. Even after the leaves have fallen, the distinct nodes on its branches make the tree easily identifiable. The Tamarack can also be identified by its small ball-shaped cones. The Tamarack tree is among the few conifers that lose their leaves in the Fall. They do so gracefully, taking on a beautiful fall coloration beforehand. The bark of Tamarack is reddish-brown, scaly, and can be delicate.
The tamarack tree is monecious, having both male and female flowers. They appear in the spring when the needles appear. The male flowers are yellow-green and the female flowers are red.
Tamaracks are very cold tolerant, able to survive temperatures down to at least −85 °F, and commonly occurs at the Arctic tree line at the edge of the tundra. Trees in these severe climatic conditions are smaller than farther south, often only 15 ft tall. They can tolerate a wide range of soil conditions but grow most commonly in swamps, bogs, or in wet to moist organic soils.
The word “Tamarack” was derived from the Abenaki Native American word “Hackmatack”, which means ‘wood for making snowshoes’. The Ojibwa people of Minnesota used the roots of the Tamarack to sew together pieces of birch bark to make their canoes as well as other things out of birch bark. Tamarack is also known for its rot-resistant wood, which has been a sought after commodity for a long time. The wood is very sturdy and today is used for house frames, railroad ties and fence posts.
The Ojibwe utilize the other parts of the tree for medicinal purposes. They crush the leaves and bark and either apply the mixture as a poultice, or place it on hot stones and inhale the fumes. Tamarack bark can be made into a tea. This tea can be utilized as a diuretic and laxative. It is also used as a remedy for sore throats. The sap of Tamarack can even be chewed to aid in indigestion. The tender spring shoots are nutritious, and can be eaten when they are boiled. The inner bark (cambium layer) of the tamarack tree can also be scraped, dried and ground into a meal to be mixed with other flours.
One tamarack that I am aware of in Worcester can be found in the Dodge Park Arboretum. Heading down the hill from the beginning of the loop it can be found starting to fill out its space on the northwest corner of the loop. I encourage you to check it out periodically this year as it goes through its many beautiful transformations from season to season.
Tree of the Week Theme: Christmas Trees!
The Balsam Fir (also known as Abies balsamea) is a very well known Christmas tree. Balsam fir trees are fast growing evergreens that are native to a wide part of North American. As a Christmas tree, balsam fir has several desirable properties. It has a dark-green appearance, long-lasting needles, and attractive form. It also retains its pleasing fragrance.
The Balsam fir can be expected to grow in hardiness zones 3–5. This is an evergreen tree so it keeps its foliage year-round. The balsam fir grows at a slow rate, with height increases of less than 12" per year, with a height of 45–75' and a spread of 20–25' at maturity.
The scientific name "balsamea" is an ancient word for the balsam tree, it was named because of the many resin containing blisters found in the bark. Balsam fir bark is thin, ash-gray, and smooth except for numerous blisters on young trees. These blisters contain a sticky, fragrant, liquid resin. The species has been sometimes referred to as "blister pine". Upon maturity, bark may become up to a 1/2 inch thick, red-brown and broken into thin scales.
The Balsam fir has both male and female flowers on the same tree. The species is wind pollinated, and cones mature in a single season. At maturity, cones are 2 to 3 1/2 inches long with bracts (modified leaf) shorter than scales. The presence of these short cone bracts is a distinguishing feature when balsam fir is compared to others. Upon ripening in September to November, cones fall apart.
Balsam bark was an important source of food for some Native American tribes. Inner bark was peeled from the tree and used to make breadstuffs. Tea is made from dried balsam needles, and is said to help sooth sore throats and congestion. The buds and resin are used in folk medicine to treat numerous ailments including bronchitis, burns, colds, heart ailments, scurvy and to heal wounds. The resin was also used as an ingredient in varnish and to fix coverslips to microscope slides. Early campers used piles of young balsam boughs as mattresses.
Balsam fir is important in forests because it provides food and cover for wildlife. Moose rely on balsam fir in winter as a major source of food. Deer use it for cover and shelter. The seeds and buds are food for birds including grouse, squirrels, mice and voles. The bark is browsed by black bears. Beavers occasionally use the wood for dam building.
Balsam fir wood is not prized for fuelwood, but industries that use balsam fir for pulp and lumber products are using increasingly larger quantities of wood waste for the production of energy. The wood is also used for light frame construction, interior knotty paneling, and crates. Wood resin in the bark blisters is the source of Canada balsam used for making of microscope slides. Resin was sold in stores as a confection prior to the advent of chewing gum, and resinous fir knots were once used as torches. A balm of balsam fir resin was used in Civil War as an external application to the injuries of combat.
Balsam fir boughs are often used for stuffing "pine pillows", with the aromatic foliage serving as a deodorant. Needles and small-diameter branches are ground or chipped and dried, and used in the manufacture of balsam fir pillows. Balsam fir pillows, as well as other items known as “fancy goods,” were made in Maine as early as the 1870’s by Shaker women in New Gloucester for sale to tourists. All parts of the tree are used so there is very little waste from the whole process.
Tree of the Week Theme: Chrismas Trees!
Leyland Cypress (x Cupressocyparis leylandii) is known for its rapid growth and slim shape. The Leyland Cypress has grown popular over large areas of the United States because of its legendary salt tolerance, thriving where many other trees will not grow. More and more Christmas tree farmers are growing Leylands due to their fast growth rate and beauty. The Leyland Cypress is very unique compared to the other two Christmas trees.
It grows well in a wide variety of soil and climate conditions and makes an excellent wind break as it provides a dense barrier with good color all 12 months of the year. You can find these beauties around homes, schools and parks.
The leyland cypress can be expected to grow in Hardiness Zones 6–10. This is an evergreen tree, keeping its foliage year-round. The Leyland cypress grows to a height of 60–70' and a spread of 15–25' at maturity. This tree grows at a fast rate, with height increases of more than 24" per year. The Leyland Cypress features dark green to bluish-green, scale-like needles that are flattened on evergreen sprays, pointed at the tips but notably soft. They produce small cones that are ½–¾" in diameter and made up of 8 scales.
This tree is a hybrid of Monterey cypress (Cupressus macrocarpa) and Alaskan cedar (Chamaecyparis nootkatensis). In 1888, six seedlings were discovered by C.J. Leyland at Leighton Hall in the South of Wales. The two parent trees were growing on the Estate and cross bred purely by accident. Crossbreeding between two Genus is a rare occurrence in plants and particularly in conifers. The resulting hybrid is sterile meaning that the original trees were the only naturally occurring trees of their kind. The trees that have now made their way around the world are all grown from cuttings that are either grafted on a root system or treated with hormones that cause them to grow roots.
In 1941, rooted cuttings arrived in United States, through California, for the first time. In 1965, they found their way to South Carolina where their potential for use as Christmas trees became apparent. The Leyland Cypress is a good choice for a Christmas tree because of it’s sprays of small, scaled needles on soft flexible limbs. It’s branches are upright and have a feathery appearance. The Leyland cypress has a very attractive shape and full branching overall.
In England, the Leyland cypress is used as in ornamental plantings and as a windbreak. In New Zealand and Australia, it is used for wood products. In the United States, it has become a valued landscape plant and one of the most sought after Christmas trees. In the landscape Leylands are aggressive allelopathic plants. This means they secrete a natural herbicide from their roots to reduce the competition from surrounding vegetation.
The Leyland Cypress are a great choice for a Christmas tree or simply a landscape tree. They provide winter cover for songbirds and game birds as well as privacy barriers for our backyards. Though Worcester is technically out of this tree's range (5b and 6 respectively) there are likely microclimates in the most developed portions where the urban heat island effect would keep temperatures higher through through the winter. Don't be surprised to see these trees in the city soon if they aren't here already!
Tree of the Week Theme: Christmas Trees!
The Scotch Pine (Pinus sylvestris, also Scots Pine) is a hardy evergreen that is easily adaptable to a wide variety of climates. This tree is another popular Christmas tree because of its form and ability to hold onto its needles for an extended period of time. This is an evergreen tree with four seasons of interest. It will always have its leaves to make it beautiful but adding to its’ beauty is the younger bark which is yellow and flaky, turning brown and rigid with age. This variation makes the tree a standout in the landscape.
The Scotch Pine can be expected to grow in hardiness zones 3–7. They reach a height of around 60’ and a spread of around 40’ at maturity and live more than 200 years in excellent conditions. The growth rate is slow to medium, with only height increases ranging from 12” to 24” per year. It features bluish green needles that vary in length and range from 1 to 3”. The color frequently changes to a yellowish green in the winter. Scotch pine is primarily a monoecious species, having male and female flowers on the same tree, meaning virtually every tree will produce a cone and seeds. They continue to produce viable seeds until at least age 200, although seed quality and size are greatly reduced. Their cones are oblong, 1–3" in length, brown, and dry. Because of its re-seeding capabilities, the Scotch pine is often used to naturally reforest cleared spaces.
As a Christmas tree Scotch pine gives a different take on the traditional due to its longer needles. This gives the tree a bushier appearance that will set your tree apart from many of the other short needled fir and spruce trees. Scotch pine is known for its excellent needle retention; it resists drying and if permitted to become dry does not drop its needles. When displayed in a water filled container it will remain fresh for the normal 3 to 4 week Christmas season. And of course, the final positive aspect of using a natural tree is that it can be left outside to return to the earth after the holidays, used for kindling, or, if you’re especially creative, you can use the wood for an craft project.
The Scotch Pine has an excellent survival rate in its native habitat and is grown on a large scale for timber products. It is native to Europe and Asia. From the British isles and Scandinavian peninsulas, everywhere in central Europe, south to the Mediterranean, and east through eastern Siberia. Because of its broad climatic tolerance it can be found at varying elevations throughout its’ range.
Scotch pine was introduced to North America by European settlers and has long been cultivated, especially in the eastern United States and Canada. Due to its’ adaptability these trees have been widely planted for both Christmas tree and ornamental purposes. Plantations have been established in the United States for the purpose of producing forest products, however the species tends not to perform as well here as in its native habitat.
The Scotch pine was widely planted on old farm fields at the turn of the century. Early farmers were familiar with this species from its growth throughout Europe and knew it could tolerate poor, dry soil. Eventually they found that the trees did not mature into the fine timber stands they envisioned, but instead they had twisted trunks. It was the beginning of the realization that seed sources vary widely and must be matched to the planting site. Today, seed sources are selected with care and certain cultivars of Scotch Pine are favored to provide the species' best qualities, especially when planting for the Christmas tree market. In the country of Scotland, the name Scots pine is preferred over the use of the term Scotch pine.
In Europe and throughout several countries in Asia, Scotch pine is an important species of high economic value. Forest stands containing Scotch pine are managed to produce pulpwood, poles, and sawlogs from which dimension and finish lumber is produced. Logs from trees of large diameters are processed and used in manufacturing plywood.
Tree of the Week Theme: Christmas Trees!
Christmas is near! Because of this, the following posts will be of many loved trees used for this popular holiday. The first on our list is the Douglas Fir. The
Douglas Fir, also known as Pseudotsuga menziesii, is an evergreen conifer. It’s one of the nation’s most important lumber species, it makes up nearly half of all Christmas trees grown in the United States.
The douglas fir can be expected to grow in Hardiness Zones 4–6. They grow to a height of 40–70' and a spread of 12–20' at maturity. The needles are arranged in a spiral around the stem, flat, elongated ovals roughly 1½" in length. The coloring of the needles depends on the variety: Coast Douglas fir has dark yellow-green (occasionally bluish-green needles); Rocky Mountain Douglas fir has bluish-green (occasionally yellow-green) needles. The Douglas Fir produces light brown, 3–4" cones which hang downward on the branches.
Douglas firs are conifers, which means that they produce seeds in cones rather than in flowers. The seeds have a single wing and are dispersed by the wind. Douglas fir seeds provide food for a number of small mammals, including chipmunks, mice, and red squirrels. These tiny rodents seek cover in nests constructed in the crowns of Douglas-firs and eat the needles.
The Douglas fir is a favorite tree used for Christmas because of the almost perfect pyramidal shape and soft, short needles that do not easily fall off. They have been the major Christmas tree species used in the Pacific Northwest since the 1920's. During the following 40 years, nearly all trees were harvested from forest lands. Since the 1950's the transformation from growing trees in the wild to culturing them on plantations has been dramatic. Today, few trees come from forest lands. The trees are shipped to the majority of the states, including the Hawaiian Islands, and is also exported to Guam and some Asian markets.
The Douglas fir was first introduced to cultivation by botanist-explorer David Douglas in 1826 and today it is the country's top source of lumber. It is one of the stronger of the softwoods and is widely used for structural purposes. The sapwood is white to pale yellow while the heartwood is orange-red. It is straight grained and moderately hard. It is used widely in construction, laminated timbers, plywood and high grade veneer, interior trim, cabinet work, pallets, boxes, ladders and flooring. The trees also have a lot of historical importance. They helped settle the West, providing railroad ties and telephone as well as telegraph poles. They were also crucial to American soldiers in World War II as the lumber was used to make the stretchers that carried many injured soldier from battle.
The Douglas fir has been and remains a very important tree to our economy and our to homes. Chances are you or one of your neighbors has one of these trees in your homes this holiday season.
Tree of the Week Theme: Bark!
The Paper Birch tree, also known as Betula papyrifera is a tree that is loved by many. Papyrifera means "paper-bearing," referring to the bark. This tree is popular in New England because of its stunning white bark and golden fall color. Its popularly planted on many landscapes, New Hampshire even made the Paper Birch its state tree!
The paper birch can be expected to grow in Hardiness Zones 2–7. I’ve seen quite a few of these beauties in Worcester myself. They grow at a medium to fast rate, with height increases of anywhere from 13" to more than 24" per year reaching a final height of 50–70' and a spread of around 35'. The canopy is an oval shape. The Paper Birch features simple leaves that are 2–4" long, double-toothed and are arranged alternately. It has very small seeds that are smooth and oval in shape, tucked between two wings. Brown and Green catkins are produced in April and May. In the fall, the paper birch is a marvelous, bright yellow color.
The paper birch develops a smooth white bark that curls and peels once it's mature. This bark besides being very attractive, has served many purposes throughout history. Long ago, people would peel layers of the thin, paper-like bark and write on it as a way to send messages. Many First Nations people in British Columbia used birch bark as material for baskets, cradles, and canoes. Another common name for paper birch is “Canoe Birch” because of its legendary association with northern Indians. Native Americans and early fur trappers used the Paper Birch tree as a resource for sleek, sturdy, and lightweight watercraft. They also used it for wrapping and storing food and for roofing pit houses. And, as anyone with experience lighting a campfire would know, strips of birch bark make great tinder.
But it’s not just the bark of the tree that is useful. the wood was used by native Americans for many small items, including bowls and spoons. Today we use birch wood for floors and veneers. Natives even drank the sap as a medicine for colds and it can be used to make birch beer, though usually Black Birch sap is preferred.
The Paper Birch is a pioneer species meaning it is often one of the first trees to grow in an area after other trees are removed by some sort of disturbance. Typical disturbances colonized by paper birch are wildfire, avalanche, or windthrow areas where the wind has blown down a broad swath of trees. When it grows in these pioneer, or early successional woodlands it often forms stands of trees where it is the only species. Paper birch is considered well adapted to fires it recovers quickly by means of reseeding the area or regrowth from the burned tree.
In the winter, moose find the abundance of paper birch crowded in multiples important because of the cover they provide, despite the poor nutritional quality. White-tailed deer eat large portions of paper birch leaves in the fall. Snowshoe hares browse paper birch seedlings and saplings, beavers find it a good second choice food and porcupines feed on the inner bark. Voles, shrews, Redpolls, siskins and chickadees eat the seeds. Numerous types of cavity-nesting birds nest in paper birch, including woodpeckers, chickadees, nuthatches and swallows. Pecking holes in the bark, the yellow-bellied sapsucker finds the paper birch a favorite tree. Hummingbirds and red squirrels then feed at sapwells created by sapsuckers. Ruffed grouse eat the flowers and buds.
The paper birch is important for species both culturally and ecologically. The graceful form and attractive white bark make it a prized species for ornamental planting and landscaping as well as a food source for wildlife. The paper birch is still greatly appreciated today.
