Defining a Forest • Forests vary in size, composition, and function
•People use forests in many ways too so their definition of what is a forest can all be different
•The people who use a forest and who value it are called stakeholders
•Defining a forest when they look so different and when there are many stakeholders can be hard

Defining a Forest •The Food and Agricultural Organization (FAO) says that a forest is land
-that is a little bigger than 1 acre in size
-where the trees cover at least 10% of it
-and the trees can grow to be at least 16 feet tall

Defining a Forest
•But the FAO definition of a forest isn’t complete
•What else is in a forest other than just trees?

• Forests can be categorized by their environmental conditions - ex. climate, elevation, soil, amount of water
• Or by what lives in the forest- ex. types of trees, birds, fungi, mammals, people, insects
• And by how they’re used – ex. for timber, to get food from, for recreation, or for wildlife
Categorizing Forests
![Page 9: What do you think of when you › extension › ee › foresthealth...What do you think of when you hear, “forest”? A place with trees A place where I hunt . For many people, trees](https://reader033.fdocuments.us/reader033/viewer/2022060509/5f24f9e1320c3114fb647098/html5/thumbnails/9.jpg)
• Despite differences in the environmental conditions in a forest, what lives in a forest, and how it is used, all forests provide services that you and I benefit from everyday.
• Can you think of any good things forests do?
Benefits Forests Provide
![Page 10: What do you think of when you › extension › ee › foresthealth...What do you think of when you hear, “forest”? A place with trees A place where I hunt . For many people, trees](https://reader033.fdocuments.us/reader033/viewer/2022060509/5f24f9e1320c3114fb647098/html5/thumbnails/10.jpg)
• Forests provide shade, clean air for us to breath, clean water for us to drink, return nutrients to the soil, and provide habitat for other plants and wildlife
• These things forests provide are called ecosystem services
• All forest types provide ecosystem services!

Now that we know what makes up a forest and what they do for us, let’s explore the different forest types …

Types of Forests
![Page 13: What do you think of when you › extension › ee › foresthealth...What do you think of when you hear, “forest”? A place with trees A place where I hunt . For many people, trees](https://reader033.fdocuments.us/reader033/viewer/2022060509/5f24f9e1320c3114fb647098/html5/thumbnails/13.jpg)
• These types of forests are usually conservation areas for wildlife, ecosystem services and wildlife
• Sometimes trees in natural forests are harvested but young trees will grow from seeds left on the ground and take their place
• Natural forests provide green areas for many people to enjoy
• Have you ever visited a natural forest?
Natural Forests
![Page 14: What do you think of when you › extension › ee › foresthealth...What do you think of when you hear, “forest”? A place with trees A place where I hunt . For many people, trees](https://reader033.fdocuments.us/reader033/viewer/2022060509/5f24f9e1320c3114fb647098/html5/thumbnails/14.jpg)
An Example of a Natural Forest
![Page 15: What do you think of when you › extension › ee › foresthealth...What do you think of when you hear, “forest”? A place with trees A place where I hunt . For many people, trees](https://reader033.fdocuments.us/reader033/viewer/2022060509/5f24f9e1320c3114fb647098/html5/thumbnails/15.jpg)
• These are forest that are specifically planted to make products people use
• Examples of products include paper, wood, fuel, oranges, and pecans
• Plantations are usually planted in rows for easy access and are privately owned
• Plantations are usually less diverse than natural forests
Plantations
![Page 16: What do you think of when you › extension › ee › foresthealth...What do you think of when you hear, “forest”? A place with trees A place where I hunt . For many people, trees](https://reader033.fdocuments.us/reader033/viewer/2022060509/5f24f9e1320c3114fb647098/html5/thumbnails/16.jpg)
An Example of a Plantation

• These forests are planted or left standing in developed areas such as in neighborhoods or cities
• Human benefits are the primary purpose of urban forests
• These benefits include providing cool shade, beauty, and taking up water after it rains
• Is there an urban forest near your school or where you live?
Urban Forests
