Grounds maintenance workers provide a pleasant outdoor environment by ensuring that the grounds of houses, businesses, and parks are attractive, orderly, and healthy.
Grounds maintenance workers typically do the following:
Grounds maintenance workers do a variety of tasks to achieve a pleasant and functional outdoor environment. They also care for indoor gardens and plantings in commercial and public facilities, such as malls, hotels, and botanical gardens.
The following are types of grounds maintenance workers:
Landscaping workers create new outdoor spaces or upgrade existing ones by planting trees, flowers, and shrubs. They also trim, fertilize, mulch, and water plants. Some grade and install lawns or construct hardscapes such as walkways, patios, and decks. Others help install lighting or sprinkler systems. Landscaping workers work in a variety of residential and commercial settings, such as homes, apartment buildings, office buildings, shopping malls, and hotels and motels.
Groundskeeping workers, also called groundskeepers, maintain existing grounds. They care for plants and trees, rake and mulch leaves, and clear snow from walkways. They work on athletic fields, golf courses, cemeteries, university campuses, and parks, as well as in many of the same settings as landscaping workers. They also see to the proper upkeep and repair of sidewalks, parking lots, groundskeeping equipment, fountains, fences, planters, and benches.
Groundskeeping workers who care for athletic fields keep natural and artificial turf in top condition, mark out boundaries, and paint turf with team logos and names before events. They mow, water, fertilize, and aerate the fields regularly. They must make sure that the underlying soil on fields with natural turf has the required composition to allow proper drainage and to support the grasses used on the field. In sports venues, they vacuum and disinfect synthetic turf after its use to prevent the growth of harmful bacteria, and they remove the turf and replace the cushioning pad periodically.
Groundskeepers in parks and recreation facilities care for lawns, trees, and shrubs; maintain playgrounds; clean buildings; and keep parking lots, picnic areas, and other public spaces free of litter. They also may erect and dismantle snow fences, and maintain swimming pools. These workers inspect buildings and equipment, make needed repairs, and keep everything freshly painted.
Some groundskeepers specialize in caring for cemeteries and memorial gardens. They dig graves to specified depths, generally using a backhoe. They mow grass regularly, apply fertilizers and other chemicals, prune shrubs and trees, plant flowers, and remove debris from graves.
Greenskeepers maintain golf courses. Their work is similar to that of groundskeepers, but they also periodically relocate holes on putting greens and maintain benches and tee markers along the course. In addition, greenskeepers keep canopies, benches, and tee markers repaired and freshly painted.
Pesticide handlers, sprayers, and applicators apply herbicides, fungicides, or insecticides on plants or the soil to prevent or control weeds, insects, and diseases. Those who work for chemical lawn or tree service firms are more specialized, inspecting lawns for problems and applying fertilizers, pesticides, and other chemicals to stimulate growth and prevent or control weeds, diseases, or insect infestations.
Tree trimmers and pruners, also called arborists, cut away dead or excess branches from trees or shrubs to clear utility lines, roads, and sidewalks. Although many workers strive to improve the appearance and health of trees and plants, some specialize in diagnosing and treating tree diseases. Others specialize in pruning, trimming, and shaping ornamental trees and shrubs. Tree trimmers and pruners use chainsaws, chippers, and stump grinders while on the job. When trimming near power lines, they usually work on truck-mounted lifts and use power pruners.
Forest and conservation workers measure and improve the quality of forests. Under the supervision of foresters and forest and conservation technicians, they help to develop, maintain, and protect forests.
Forest and conservation workers typically do the following:
Forest and conservation workers are often supervised by foresters and forest and conservation technicians, who direct their work and evaluate their progress.
They do basic tasks to maintain and improve forest quality, such as planting seedlings or removing diseased trees. To plant seedlings, they use digging and planting tools. To cut trees, they use handsaws or power saws.
Some forest workers work on tree farms, where they plant, cultivate, and harvest many different kinds of trees. Their duties vary with the type of farm and may include planting seedlings, spraying to control weed growth and insects, and harvesting trees.
Some forest and conservation workers work in forest nurseries, where they sort through tree seedlings, discarding those that don't meet standards. Others use hand tools or their hands to gather woodland products, such as decorative greens, tree cones, bark, moss, and other wild plant life. Some may tap trees to make syrup or chemicals.
Forest and conservation workers who are employed by or under contract with state and local governments may clear brush and debris from trails, roadsides, and camping areas. They may clean kitchens and rest rooms at recreational facilities and campgrounds.
Workers with a fire protection background also help to prevent fires. For example, they may construct firebreaks, which are gaps in vegetation that can help slow down or stop the progress of a fire. They also may work with technicians to study how quickly fires spread and how successful fire suppression activities were. For example, workers help count how many trees will be affected by a fire. They also sometimes respond to forest emergencies.
Surveyors establish land, airspace, and water boundaries. They measure the Earth's surface to collect data that are used to draw maps, determine the shape and contour of parcels of land, and set property lines and boundaries. They also define airspace for airports and measure construction and mining sites. Surveyors work with civil engineers, landscape architects, and urban and regional planners to develop comprehensive design documents.
Surveyors typically do the following:
Surveyors guide construction and development projects and provide information needed for the buying and selling of property. In construction, surveyors determine the precise location of roads or buildings and proper depths for foundations and roads. Whenever property is bought or sold, it needs to be surveyed for legal purposes.
In their work, surveyors use the Global Positioning System (GPS), a system of satellites that locates reference points with a high degree of precision. Surveyors interpret and verify the GPS results. They gather the data that is fed into a Geographic Information System (GIS), which is then used to create detailed maps.
Surveyors take measurements in the field with a crew, a group that typically consists of a licensed surveyor and trained survey technicians. The person in charge of the crew (called the party chief) may be either a surveyor or a senior surveying technician. The party chief leads day-to-day work activities. For more information, see the profile on surveying and mapping technicians.
Some surveyors work in specialty fields to survey particular characteristics of the Earth. Examples include the following:
Geodetic surveyors use high-accuracy techniques, including satellite observations, to measure large areas of the Earth's surface.
Geophysical prospecting surveyors mark sites for subsurface exploration, usually to look for petroleum.
Marine or hydrographic surveyors survey harbors, rivers, and other bodies of water to determine shorelines, the topography of the bottom, water depth, and other features.
Logging workers harvest thousands of acres of forests each year. The timber they harvest provides the raw material for countless consumer and industrial products.
Logging workers typically do the following:
Timber-cutting and logging are done by a logging crew. The following are some types of logging workers:
Fallers cut down trees with hand-held power chain saws or mobile felling machines.
Buckers trim the tops and branches of felled trees and buck (cut) the logs into specific lengths.
Choke setters fasten chokers (steel cables or chains) around logs to be skidded (dragged) by tractors or forwarded by the cable-yarding system to the landing or deck area, where the logs are separated by species and type of product, such as pulpwood, saw logs, or veneer logs, and loaded onto trucks.
Rigging slingers and chasers set up and dismantle the cables and guy wires of the yarding system.
Log sorters, markers, movers, and chippers sort, mark, and move logs, based on species, size, and ownership, and tend machines that chip up logs.
Logging equipment operators use tree harvesters to fell trees, shear tree limbs off, and cut trees into desired lengths. They drive tractors and operate self-propelled machines called skidders or forwarders, which drag or transport logs to a loading area.
Log graders and scalers inspect logs for defects and measure the logs to determine their volume. They estimate the value of logs or pulpwood. These workers often use hand-held data collection devices to enter data about trees. The data are later downloaded to a computer.
A typical crew might consist of
Landscape architects plan and design land areas for parks, recreational facilities, highways, airports, and other properties. Projects may include subdivisions and commercial, industrial, and residential sites.
Landscape architects typically do the following:
People enjoy attractively designed gardens, public parks, playgrounds, residential areas, college campuses, and golf courses. Landscape architects design these areas so that they are not only functional but also beautiful and harmonious with the natural environment.
Landscape architects plan the locations of buildings, roads, and walkways. They also plan where to plant flowers, shrubs, and trees. Landscape architects design and plan the restoration of natural places disturbed by humans, such as wetlands, stream corridors, and mined areas.
Many landscape architects specialize in a particular area, such as beautifying or otherwise improving streets and highways, waterfronts, parks and playgrounds, or shopping centers.
Increasingly, landscape architects are working in environmental remediation, such as preserving and restoring wetlands or managing storm-water runoff in new developments. They are also increasingly playing a role in preserving and restoring historic landscapes.
Landscape architects who work for government agencies do design sites and landscapes for government buildings, parks, and other public lands, as well as plan for landscapes and recreation areas in national parks and forests.
In addition, they prepare environmental impact statements and studies on environmental issues, such as planning for use of public lands.
