Conservation scientists typically do the following:

• Oversee forestry and conservation activities to ensure compliance with government regulations and habitat protection
• Negotiate terms and conditions for forest harvesting and land-use contracts
• Establish plans for managing forest lands and resources
• Monitor forest-cleared lands to ensure that they are suitable for future use
• Work with private landowners, governments, farmers, and others to improve land for forestry purposes, while at the same time protecting the environment

Foresters typically do the following:

• Supervise activities of forest and conservation workers and technicians
• Choose and prepare sites for new trees, using controlled burning, bulldozers, or herbicides to clear land
• Monitor the regeneration of forests
• Direct and participate in forest fire suppression
• Determine ways to remove timber with minimum environmental damage

Conservation scientists manage, improve, and protect the country's natural resources. They work with private landowners and federal, state, and local governments to find ways to use and improve the land while safeguarding the environment. Conservation scientists advise farmers, ranchers, and other agricultural managers on how they can improve their land for agricultural purposes and to control erosion.

Foresters have a wide range of duties, and their responsibilities vary with their employer. Some primary duties of foresters are drawing up plans to regenerate forested lands, monitoring the progress of those lands, and supervising tree harvests. Another duty of a forester is devising plans to keep forests free from disease, harmful insects, and damaging wildfires. Many foresters supervise forest and conservation workers and technicians, directing their work and evaluating their progress.

Conservation scientists and foresters evaluate data on forest and soil quality, assessing damage to trees and forest lands caused by fires and logging activities. In addition, they lead activities, such as suppressing fires and planting seedlings. Fire suppression activities include measuring how quickly fires will spread and how successfully the planned suppression activities turn out. 

Conservation scientists and foresters use their skills to determine a fire's impact on a region's environment. Communication with firefighters and other forest workers is an important component of fire suppression and controlled burn activities because the information that conservation scientists and foresters provide can determine how firefighters work.

Conservation scientists and foresters use a number of tools to perform their jobs. They use clinometers to measure the heights of trees, diameter tapes to measure a tree's circumference, and increment borers and bark gauges to measure the growth of trees so that timber volumes can be computed and growth rates estimated.

In addition, conservation scientists and foresters often use remote sensing (aerial photographs and other imagery taken from airplanes and satellites) and geographic information systems (GIS) data to map large forest or range areas and to detect widespread trends of forest and land use. They make extensive use of handheld computers and global positioning systems (GPSs) to study these maps.

The following are examples of types of conservation scientists:

Conservation land managers work for land trusts or other conservation organizations to protect the wildlife habitat, biodiversity, scenic value, and other unique attributes of preserves and conservation lands.

Range managers, also called range conservationists, protect rangelands to maximize their use without damaging the environment. Rangelands contain many natural resources and cover hundreds of millions of acres in the United States, mainly in the western states and Alaska.

Range managers may inventory soils, plants, and animals; develop resource management plans; help to restore degraded ecosystems; or help manage a ranch. They also maintain soil stability and vegetation for uses such as wildlife habitats and outdoor recreation. Like foresters, they work to prevent and reduce wildfires and invasive animal species.

Soil and water conservationists give technical help to people who are concerned with the conservation of soil, water, and related natural resources. For private landowners, they develop programs to make the most productive use of land without damaging it. They also help landowners with issues such as dealing with erosion. They help private landowners and governments by advising on water quality, preserving water supplies, preventing groundwater contamination, and conserving water.

The following are examples of types of foresters:

Procurement foresters buy timber by contacting local forest owners and negotiating a sale. This activity typically involves taking inventory on the type, amount, and location of all standing timber on the property. Procurement foresters then appraise the timber's worth, negotiate its purchase, and draw up a contract. The forester then subcontracts with loggers or pulpwood cutters to remove the trees and to help lay out roads to get to the timber.

Urban foresters live and work in larger cities and manage urban trees. They are concerned with quality-of-life issues, including air quality, shade, and storm water runoff. 

Conservation education foresters train teachers and students about issues facing forest lands.
