How to Use this book:
This book is designed to be a user-friendly, functional field guide for Connecticut’s “Quiet Corner.” Within, you should find many of the plants
you are likely to see on any given day in the forest. Don’t expect to find information on rare and endangered species here; the focus is on
common plants, where they are likely to be found, and how to deal with them.
This book is not organized like a traditional botanical guide. Rather, species are sorted based on their most obvious characteristics. Thus, if
the plant you are looking at is a woody-stemmed species with opposite leaves/branches and a simple leaf, please turn to page 6.
If it is opposite branching but with compound leaves, please turn to page 11.
If it is alternate branching with simple leaves, please turn to page 12.
If it is alternate branching with compound leaves, please turn to page 30.
If it is a conifer, please turn to page 35.
If it is a woody shrub without thorns, please turn to page 39.
If it is a woody shrub with thorns, please turn to page 47.
If it is a vine, please turn to page 52.
If it is an herbaceous flowering plant, please turn to page 55.
If it is a fern or a fern-type plant (a fern ally), please turn to page 70.
An example is included on the following page to help you sort through the information you will find on each species.

Strong wood and resistance to shock has made it a good wood for
handles, oars, and baseball bats. Also makes excellent firewood.
Shelterwood and overstory removal treatments are useful
strategies for management; as seedlings have been shown to
develop best in at least 45 percent of full sunlight
strong apical dominance

Red oak, Quercus rubra (Fagaceae)
●
●
●
●
Leaves: Lobed leaves with pointed, bristle-tipped ends
Buds/Twigs: Pointed buds clustered at shoot tips. Possibly a
few hairs at bud tips, but not hairy
Stem: Large trees have brownish bark with smooth vertical
sections separated by rough grooves, producing the “ski
tracks” look
Flowers/Fruits: 3/4 to 1 inch long acorns have shallow caps,
can be single or in pairs
•
•
•
Grows best on deep, well-drained loam to silty, clay loam soil
Driving factors of site quality are depth and texture of the A
soil horizon, aspect, and slope position and shape. Prefers
soils with a thick A horizon, and a loam to silt loam texture
Intermediate shade tolerance (more than white, black, or
scarlet oaks)

•
•
Hybridizes readily with black and scarlet oak
Responds well to release if trees are codominant or above
May see epicormic sprouting following heavy thinning in stands
older than about 30 years or on trees around the perimeter of
openings, because the boles contain numerous dormant buds
More shade tolerant than Black oak
Masting is very irregular
Shelterwood treatments, uniform or irregular, are best for
regeneration
Most susceptible to gypsy moth (Lymantria dispar)
Oak wilt, root rot, carpenterworm (Prionoxystus robiniae)

●
●
Leaves: Lobed leaves with pointed, bristle-tipped ends
Buds/Twigs: Pointed buds clustered at shoot tips. Velvety,
hairy buds have flattened sides (which are more easily seen
when viewing from the top of the bud)
Stem: Clear examples of black oak will have grayish-black,
blocky bark (with blocks being 1-2 inches in size), especially
on the lowest part of the stem
•
•
Soils: Grows best on dry, well-drained, silty clay to loam
soils; can also grow on cool, moist spodosols
Site quality driven by thickness and texture of the A horizon,
texture of the B horizon, aspect, and slope position. Grows in
coves and on upper slopes

(drought, defoliation, etc.) leads to secondary agent (fatal)
such as root rot
Alternate
Simple
Hybridizes readily with red and scarlet oaks
Intermediate shade tolerance
Sprouts under mature stands can develop crooked stems and flattopped or misshapen crowns
Even-aged management or shelterwood preferred to all-aged or
selection system (inadequate light will preclude regeneration).
Trees can be easily dominated by more shade-tolerant species.
Responds well to release if in the codominant or above-average
intermediate crown classes
Frequent cavities have high wildlife value

●
●
Leaves: Elliptic to ovate with prominent pinnate veins and
toothed margins
Buds/Twigs: Buds long and pointed, 1/2 to 3/4 inches long
Stem: Smooth and silvery gray in all sizes, though it may look
rough and scarred from Beech bark disease
•
•
•
•
Soils: Soils of loamy texture and those with a high humus
content are more favorable than lighter soils
Grows on mesic sites
Very shade tolerant. Grows slowly in the understory, then
grows rapidly when canopy is opened

•
•
•
•
Disturbances

•
•
Impacted by beech bark disease (Nectria coccinea)
Susceptible to forest tent caterpillar and gypsy moth
Highly intolerant to fire due to thin bark
Can be damaged by frost, particularly in the late spring
Sensitive to flooding
•
Tendency to sprout from both base and roots can create
management difficulties, because of the potential for the formation
of monodominant thickets
Seedlings grow best under a moderate canopy or in protected small
openings where the soil does not dry out below the depth of the
shallow roots
Tends to be a poor deer browse
Selection cuts will allow beech to flourish and may be suppressed
by overstory removal treatments that allow less shade tolerant
species to grow more quickly upon release
Important hard mast species for wildlife

Chestnut, Castanea dentata (Fagaceae)
●
●
●
●

•
Once a common species, the chestnut was nearly eliminated by the
chestnut blight, a fungal disease imported from Asia

20 ft in height before becoming infected
Prized as a timber tree particularly due to a faster growth rate than
oaks
Ongoing studies are testing possible reintroduction using resistant
