Where would we be without plants? They are the basis of the food chain and producers of oxygen - and so much more. From marsh grasses to mangroves, from sagebrush to sunflowers, getting to the root of the biology and ecology of plants is a critical component of USGS research.
An Integral Part of Life on Earth
Life as we know it wouldn’t be possible without plants. Plants maintain the atmosphere by producing oxygen and absorbing carbon dioxide, help keep our waterways clean, and provide us with food, shelter, and medicine. Plant communities are influenced by soil, terrain, climate, animals, and human activities, so different groups and types of plants are found in different regions of the country. Grassland plants such as the western prairie fringed orchid are found in the Great Plains, while desert plants such as the saguaro cactus are found in the Southwest. Approximately 391,000 species of vascular plants are currently known to science. Explore examples of USGS science on different plant types below.
Science to Support Healthy Ecosystems
Healthy plants are the foundation of healthy ecosystems. In an era of global change, our Nation’s forests, grasslands, wetlands, and other critical habitats are facing multiple threats that challenge our ability to maintain these ecosystems and the species that depend on them. USGS science provides the information needed to address these challenges and support healthy, thriving plant communities across the country.
Threats to Plants
Understanding, monitoring, and predicting threats to plants contributes to the USGS goal of providing science to support the protection, conservation, and enhancement of the Nation’s biodiversity. Through activities such as identifying strategies for controlling invasive cheatgrass, using novel techniques to identify the presence of disease-causing plant pathogens, and informing recovery plans for at-risk species, USGS science is tackling some of the biggest threats facing plants today.
Land Use Change
The single biggest threat facing plants today is habitat loss. Changes in land use, such as the encroachment of agriculture or urban development into areas that were once covered by natural vegetation, reduce plant population sizes and alter the ecosystems that plants, animals, and humans rely on. Changes in land use can cause species extinctions, destabilize soil, increase erosion, and reduce water quality. USGS scientists are monitoring changes in land use to understand how they are affecting the plants and wildlife that depend on them. Explore examples of our science below:
- Monitoring and assessing the effectiveness of habitat management projects in southwest Wyoming, a 19-million-acre region that supports some of the highest quality wildlife habitats in the Intermountain West, as well as agriculture and energy production. Learn more>>
- Identifying the effects of wind turbines and associated infrastructure on vegetation and how wildlife use these landscapes. Learn more>>
- Understanding how agricultural drainage systems affect wetlands in the Prairie Pothole Region. Learn more>>
- Using satellite imagery to monitor changes in vegetation across the country. Learn more>>
Invasive Plants
Every plant and animal species has a native range where it evolved. When a species exists in a location beyond its natural range, it is considered a “non-native” species in that area. When a non-native species establishes in a new habitat, causing harm to the environment or humans, it becomes “invasive”. The annual estimated economic and health-related costs of invasive species in the U.S. have been reported at more than $21 billion and adversely affect every state in the country. Invasive plants represent a major threat to global and local biodiversity while also having negative socio-economic and human health impacts. Invasive plants displace native plants, prevent native plant growth, reduce agricultural production, and induce allergies.
Invasive plants such as cheatgrass and buffelgrass have increased fire vulnerability and diminished grazing value across the western U.S. Aquatic invasive plants such as the weed hydrilla and giant fern salvinia are clogging waterways. To help combat these invaders, USGS scientists are using new tools to model the potential spread of high impact invasive species and to support the early detection and rapid response of invasive species before they are able to spread and cause harm. If an invasive plant is already established, USGS science is helping land managers reverse and mitigate the negative impacts these invasions are causing. Explore examples of our science to understand and reduce the threat of invasive plants below:

- Developing the Nonindigenous Aquatic Species (NAS) Alert Risk Mapper: A tool to characterize waterbodies at risk of invasion from new non-native species. Learn more>>
- Using Unmanned Aerial Systems (UAS) to track the spread of Salvinia molesta, a non-native aquatic species that reduces light and oxygen levels in water, making it unsuitable for fish and other aquatic life. Learn more>>

USGS research is addressing numerous diseases in both plants and animals and leading development efforts in advanced tools such as environmental DNA (eDNA) to assist in prevention and early detection. Explore examples of our science on plant diseases and pathogens below:
- Using new environmental DNA (eDNA) methods to identify the presence of pathogens known to cause the decline of eelgrass, which provides important habitat for birds, fish, and invertebrates in southwestern Alaska. Learn more>>
- Deploying a portable lab to speed detection of pathogens responsible for Rapid ‘Ōhi‘a Death (ROD), a rapidly spreading disease affecting a keystone tree species in Hawai’i. Learn more>>
- Using decades of Landsat satellite imagery to map bark beetle outbreaks, which have devastated certain species of evergreen trees in the Rocky Mountains. Learn more>>
Climate Change
Climate helps shape ecosystems. Things like average temperatures, humidity, and rainfall determine where plants and animals lives. If a region’s climate changes, the ecosystem changes as well. Climate change poses one of the biggest threats to plants, leading to an increased spread of invasive species, increased vulnerability to insect pests, the loss of native plant species and changes in their distribution. USGS scientists are leading efforts to understand the current and future impacts of climate change on plants. This information helps management agencies identify adaptation strategies and actions that can help support vulnerable plant species in the face of a changing climate. Explore examples of our science below:
- Monitoring the conversion of tidal freshwater wetlands in the Southeast and mid-Atlantic to “Ghost Forests”—forests in which trees have died due to increases in salinity as sea levels rise and push saltier water upstream. Learn more>>
- Identifying how changes in the amount and timing of precipitation affect big sagebrush in the Great Basin. Learn more>>
- Investigating the effects of drought and warming temperatures on plants in the southwestern U.S. Learn more>>
- Exploring the effects of estimated future sea-level rise on mangrove forests in Micronesia. Learn more>>
- Using satellite data to monitor changes in phenology, or the study of animal and plant life cycles, a powerful tool for understanding life cycle trends and the impacts of climate change on ecosystems. Learn more>>
Species at Risk
As a result of threats such as the spread of invasive species, disease, and climate and land use change, some plant species are in decline or in danger of extinction. The USGS provides management agencies such as the U.S. Fish and Wildlife Agency and National Park Service with scientific information to support conservation decisions for at-risk plant species. Explore examples of our science below:

Ecosystem Restoration
Ecosystem restoration is the act of rehabilitating a degraded or lost ecosystems through activities such as planting native trees and shrubs and controlling invasive species. To do this, land managers need tools to help get the right plants, in the right place, at the right time for successful restoration. The USGS develops strategies and techniques to understand and facilitate the restoration of native species and habitats that have deteriorated due to threats such as invasive species and climate change.

Biological carbon sequestration is the natural ability of life and ecosystems to store carbon. Forests, peat marshes, and coastal wetlands are particularly good as storing carbon. Carbon can be stored in plant tissue, such as long-lived tree bark or in extensive root systems. Microbes break down plant and animal tissue through decomposition.
