What is in a hardwood forest?
The northern hardwoods forest type includes many tree species, which vary by site and geographic range. Species may include sugar maple, American basswood, white ash, black ash, yellow birch, red maple and elms. Occasionally, aspen, paper birch, balsam fir and northern red oak are important.
Why are hardwood forests important?
Aside from scenic beauty these forests provide recreation, water, timber products, fuel, and essential habitats for wildlife. The social and economic benefits of the central hardwood forests, while of great value, can be increased substantially with better management.
What is a hardwood tree?
The term “hardwood tree” is a botanical grouping of trees with similar characteristics. Hardwood tree characteristics apply to many of the tree species in this country. The trees have broad leaves rather than needle-like leaves. They produce a fruit or nut, and often go dormant in the winter.
Where are hardwood forests?
Description. Bottomland hardwood forests are river swamps. They are found along rivers and streams of the southeast and south central United States, generally in broad floodplains.
Where are hardwood forests found?
The northern hardwood forest is a general type of North American forest ecosystem found over much of southeastern and south-central Canada, Ontario, and Quebec, extending south into the United States in northern New England, New York, and Pennsylvania, and west along the Great Lakes to Minnesota and western Ontario.
What is hardwood regeneration?
Most hardwood regeneration occurs naturally—that is, without planting trees—but many factors can affect forest regeneration. To regenerate naturally, the current forest must produce seedlings, stump sprouts, and root suckers that will become the next forest following a harvest or natural disturbance.
What is upland forest?
Forest:Present:Upland. Upland forests occur where drainage is sufficient so that soils do not become saturated for extended periods of time. Water can either run off or percolate through the soil. The upper canopy is 80% to 100% closed, and sub-canopies of younger trees and shrubs typically exist.
What is meant by coniferous forest?
Coniferous forests consist mostly of conifers, which are trees that grow needles instead of leaves and cones instead of flowers. Conifers tend to be evergreen—they bear needles all year long. These adaptations help conifers survive in areas that are very cold or dry.
Why is hardwood important to agriculture?
High density hardwood plantations help to promote good timber form, while simultaneously providing habitat for certain wildlife species. Hardwood plantations can help to mitigate these negative effects by filtering pollutants before they reach water supplies.
What are the examples of hardwood?
Examples of hardwood include iroko, ash, beech, alder, teak, birch, mahogany, maple, oak, balsa and walnut.
What trees are made of hardwood?
Hardwoods come from broadleaved trees such as oak, ash and beech. These trees take much longer to grow, up to 150 years before they are ready to harvest.
What animals live in hardwoods?
The forests provide excellent habitat for many species of birds such as blue herons, wood storks, red-headed woodpeckers and Kentucky warblers. Many mammal species also make their home in these habitats. Black bears, squirrels, skunks, beavers, fox among many others are commonly found in bottomland hardwood forests.
What does a hardwood forest look like?
Northern Hardwood Forest can be quite similar to Oak-Maple Forest (large Red Oak trees are prevalent in both habitats), but is distinguished by the presence of Hemlock, Beech, Yellow Birch, and/or Basswood, and the rarity of any oaks other than Red Oak.
What is in a deciduous forest?
A forest that is dominated by trees that lose their leaves in the fall is called a deciduous forest. Wyoming deciduous tree species include aspen, cottonwood, box elder, ash, mountain ash, poplars, willows, fruit trees such as the wild plum and less commonly oak and maple.
What are 3 types of wood?
The Three Main Types of Wood. Before we get into all of the different wood varieties and their common uses, it's important to understand the three basic types of wood you might encounter. These three types are: softwoods, hardwoods, and engineered wood.

What are Hardwood Trees?
The term “hardwood tree” is a botanical grouping of trees with similar characteristics. Hardwood tree characteristics apply to many of the tree species in this country. The trees have broad leaves rather than needle-like leaves. They produce a fruit or nut, and often go dormant in the winter.
What percentage of trees are hardwood?
They produce a fruit or nut, and often go dormant in the winter. America’s forests contain hundreds of different hardwood tree species. In fact, about 40 percent of American trees are in the hardwood category.
How to tell if a hardwood tree is deciduous?
A few simple tests help you differentiate hardwood from softwood trees. Hardwood information specifies that hardwood trees are deciduous. This means that the leaves fall off in autumn and the tree remains leafless through springtime. On the other hand, softwood conifers do not pass the winter with bare branches.
What are the types of trees that bear seeds?
Softwood lumber is often used in building. In the U.S., you’ll find that common softwoods include: Cedar. Fir. Hemlock. Pine. Redwood. Spruce.
Do conifers pass the winter?
On the other hand, softwood conifers do not pass the winter with bare branches. Although sometimes old needles fall off, the softwood tree branches are always covered with needles. According to hardwood information, almost all hardwoods are flowering trees and shrubs.
What are the most important hardwoods in Pennsylvania?
This fold out details the ten most important hardwood species in Pennsylvania including oaks, maples, black cherry , and others. People often want to learn how to identify trees. There are many practical reasons for "knowing" trees, and mastering this skill builds appreciation for natural diversity.
What percentage of trees in Pennsylvania are hardwoods?
Hardwood trees lose their leaves each autumn. The wood of these trees is generally hard and dense, but there are exceptions. About 90 percent of all the trees in Pennsylvania's forests are hardwoods. The remaining 10 percent are softwoods.
What are the leaves on a hardwood tree in Pennsylvania?
Every hardwood tree species in Pennsylvania has either simple or compound leaves. Simple leaves are by far the most common. A simple leaf has two main parts. The first part is the blade. The blade is the broad, flat, and green tissue typically called "the leaf." The second part is the leaf stalk, which connects the blade to the tree's branch. At the base of a simple leaf stalk, on the tree's branch, is a bud. This bud will grow into a new branch with leaves or flowers the following year. When a simple leaf falls from the tree in autumn, the blade and stalk drop to the ground together, while the bud stays behind on the branch.
How to identify a tree?
People look at many different things to identify trees. They examine leaves, flowers, bark, twigs, fruits, seeds, tree shape, wood characteristics, wood anatomy, chemicals, genetics, odors, and even flavors. Botanical classification and grouping of trees use flowers. However, looking at tree leaves is perhaps the easiest way to start learning identification. The biggest drawback is that hardwood trees don't have leaves year-round! Some basic information about hardwood leaves can help you get started.
How many species of trees are there in Pennsylvania?
Pennsylvania has over 100 native tree species, but there are seldom more than 10 to 15 different species in any one location. This publication presents information about 10 important Pennsylvania hardwood tree species--their identification, characteristics, and wood.
What is the most common maple tree in Pennsylvania?
Red maple, also called "soft maple" or "swamp maple," is the most common tree species in Pennsylvania in terms of both the actual number of trees and the volume of wood available. This species grows over a wide range of conditions. It has simple, opposite leaves, with three and sometimes five pointed lobes.
What is a tree key?
When learning tree identification, a "tree key" is often useful. Keys provide a step-by-step method of looking at tree characteristics for identification . While such keys usually deal with leaf characteristics, they are also available for tree bark, buds, fruits and cones.
How do bottomland hardwoods help the watershed?
Bottomland Hardwoods serve a critical role in the watershed by reducing the risk and severity of flooding to downstream communities by providing areas to store floodwater. In addition, these wetlands improve water quality by filtering and flushing nutrients, processing organic wastes, and reducing sediment before it reaches open water.
Where are bottomland forests found?
Bottomland hardwood forests are river swamps. They are found along rivers and streams of the southeast and south central United States, generally in broad floodplains. These ecosystems are commonly found wherever streams or rivers at least occasionally cause flooding beyond their channel confines. They are deciduous forested wetlands, made up of different species of Gum ( Nyssa sp.) and Oak ( Quercus sp.) and Bald Cypress ( Taxodium distichum ), which have the ability to survive in areas that are either seasonally flooded or covered with water much of the year. Identifying features of these wetland systems are the fluted or flaring trunks that develop in several species, and the presence of knees, or aerial roots.
What woods have buttresses?
Bottomland Hardwoods. Bald Cypress trees often have buttresses, like the ones in this picture, and knees. The rings on the bases of these trees show that the water level is often higher in this forest.
How many acres are there in the bottomland forest?
Two hundred years ago, magnificent bottomland forests covered almost thirty million acres across the Southeastern United States. Today, only about forty percent of that area still supports these productive and unique ecosystems.
What is tropical hardwood?
To break it down for you, hardwood can be classified into three main types: Tropical hardwoods are essentially all hardwoods that are scientifically classified as ‘angiosperm’ – as their seeds are encased in fruits or pods.
Why is oak considered a hardwood?
The reason for oak’s, and other hardwoods, impeccable strength is because they are from slow growing trees, which means the trees’ cellular structure is more dense, compared to faster growing softwoods.
How to fix scratches on hardwood floors?
Also, any scratches or dents in hardwoods can easily be fixed by sanding, varnish and waxing to restore its beauty, rather than having to replace the damaged area. We’ve already established how hardwoods are more durable because of the slow-growing trees, although some differ in strength to others.
What is the best hardwood for joinery?
Another hardwood recommended for its high durability is Iroko (West African origin) and can be used for various internal and external joinery projects.
Why are hardwoods more durable than softwoods?
Hardwoods are naturally more durable as they come from slow-growing, broad-leaved trees. This means the timber has a higher density than softwoods, which gives them enhanced durability and strength.
How long does hardwood last?
However, hardwood will last a lifetime – so just think of it as an investment. For example, hardwood floors can actually increase the value of a property – think about how old and used a carpet will look in just a few years. Wood floors, on the other hand, will last for years and with little maintenance, can be brought up to scratch, looking like new. And that beautiful hardwood coffee table you’ve got? That’ll outlive all of its flat-pack, softwood friends.
How much does wood flooring cost?
You can probably expect to pay in the region of £30.00 to £130.00 per square metre for real-wood flooring.
What is bottomland hardwood?
Bottomland hardwood forests are one of many important riparian ecosystems in the United States . The term “bottomland hardwoods” was first used to describe forests of the southeastern US that occurred on river floodplains. Years later, Huffman and Forsythe (1981) used the term to describe floodplain forests throughout the eastern and central US that have the following characteristics:
What is the name of the primary parts of valleys of slow-moving river systems?
VII. Low terrace. Form the primary parts of valleys of slow-moving river systems.
What is the ecological zone of bottomland?
Bottomland hardwood forests typically have distinct ecological zones at different elevations and flood frequencies. These zones are the result of an active river cutting its banks and forming new land (Putnam 1960). The soil which erodes from the bank is often deposited on the inside bend downstream on what is referred to as a Point Bar. As the erosion continues, sedimentation buildup increases the height and extent of the point bar and is considered New Land. Repeated flooding raises these bars above the normal high-water level creating what is referred to as Front Land.
What are the ecosystems of the bottomland?
Bottomland hardwood forests are one of many important riparian ecosystems in the United States. The term “bottomland hardwoods” was first used to describe forests of the southeastern US that occurred on river floodplains. Years later, Huffman and Forsythe (1981) used the term to describe floodplain forests throughout the eastern and central US that have the following characteristics: 1 The area is periodically inundated or saturated by surface or groundwater during the growing season. 2 Soil saturation occurs periodically within the root zone during the growing season. 3 Common tree species in the area have morphological and/or physiological adaption (s) which allow them to survive, reach maturity, and reproduce in an environment where the soils within the root zone may become anaerobic during periods of the growing season.
What is the morphological adaptation of a tree?
Common tree species in the area have morphological and/or physiological adaption (s) which allow them to survive, reach maturity, and reproduce in an environment where the soils within the root zone may become anaerobic during periods of the growing season.
Why is the forest production process not linear?
The production process is not linear because other factors must be considered, including marketable and non-marketable goods, financial benefits, management practices, and the environmental implications, of those management practices. Forests include market and non-market products.
What are marketable products in forest?
Forests include market and non-market products. Marketable products include goods that have a market price. Timber is the main one, with prices that range from a few hundred dollars per thousand board feet (MBF) to several thousand dollars for a veneer log. Others include grazing/fodder, specialty crops such as mushrooms or berries, ...
How does timber harvesting affect the ecosystem?
But management can also harm the ecosystem; for example, machinery used in a timber harvest can compact the soil, stress the root system, reduce tree growth, lengthen the time needed for a stand to mature to harvestability. Machinery can also damage the understory, disturbing wildlife habitat and prevent regeneration.
