Indicators of Rangeland Health
Rangelands are natural ecosystems where the native vegetation consists predominantly of grasses, grass-like plants, forbs, or shrubs. Rangelands include natural grasslands, savannas, shrublands, oak and pinyon-juniper woodlands, many deserts, tundra, alpine communities, marshes, and wet meadows.
Ecology of Rare and Declining Species and Communities of Conservation Concern
Special status species and habitats are often sentinels of accelerated ecosystem change and, by definition, are priorities for protection, restoration, or focused management.
Native Plant Materials for Ecological Restoration of Degraded Drylands
There is a growing consensus among resource managers to use native plant materials for ecological restoration of degraded drylands. Some plant species may be suitable for re-introduction across broad environmental gradients. Other species may fail under narrower conditions, or their re-introduction may have genetic consequences for local ecotypes, particularly when adapting to future climate...
Aridlands Disturbances and Restoration Ecology
Desert landscapes are rapidly changing due to increases in invasive plant species, frequency of wildfires, urban and energy development, recreational use, military training, and climate variation. Dr. Todd Esque, USGS researchers, and collaborators are working together to investigate these changes and provide managers with key information that can be used to manage natural resources more...
Drivers of Ecosystem Recovery on Santa Rosa Island
The Channel Islands were used as ranches for almost 150 years. Sheep, cattle, pigs and other livestock grazed on native perennial scrub, leaving behind barren landscapes that could not collect moisture from coastal fog. In time, ranching ended and livestock were removed. WERC’s Dr. Kathryn McEachern is monitoring habitat recovery and testing the efficacy of restoration practices on the islands for...
Thresholds to Restoration
Mesic forests of Hawai‘i island provide an ideal system for the study of forest restoration because they have a similar history to other tropical and subtropical forests globally, while maintaining a relatively simple species assemblage. Many of these forests were cleared for grazing, and then later abandoned, to become dominated by pasture grasses that form competitive layers such that native...
Sea-Level Rise and Tsunami Vulnerability of Habitat and Wildlife of the Northwestern Hawaiian Islands
Low-elevation Pacific islands are vulnerable to inundation from sea-level rise and sudden flooding events. The largely low-lying islands of Northwestern Hawaiian Islands (NWHI), that extend 1,930 km beyond the main Hawaiian Islands, are a World Heritage Site and part of the Papahānaumokuākea Marine National Monument. The NWHI support the largest tropical seabird rookery in the world, provide...
Restoration and Ecosystem Recovery Dynamics in Arid and Semiarid Landscapes
Dryland regions have been degraded by invasive species, wildfire, overgrazing, agricultural conversion, energy development, recreational activity, and urban growth. These disturbances and others are accelerated by one of the fastest growing human populations in the country and a pressing background of decreasing water availability due to drought and elevated temperatures that are projected to...
Colorado Plateau Native Plant Program Field Trial Study
In the southwest US, monsoon precipitation increases sharply along a northwest to southeast gradient. Pleuraphis jamesii or galleta grass, is an important C4 grass species that spans across this large range in precipitation pattern. In this study we are assessing the ability of galleta grass to adapt to changes in the seasonality of rainfall (termed “plasticity”). In the fall of 2014, we...
New Approaches for Restoring Colorado Plateau Grasslands
Historic over-grazing of arid grasslands in the Intermountain West has led to widespread soil erosion, loss of plant diversity, and invasion by exotic species. Degraded grassland conditions can be very persistent, even after livestock use has ceased. For example, in national parks on the Colorado Plateau, livestock have been excluded for decades, but soil and native plants have not recovered on...
Impact of Sea-Level Rise on Coastal Plants and Cultural Sites
One of the impacts of global climate change for the Hawaiian Islands is a projected increase in sea level of about one meter by the year 2100. This change will impact both biological and cultural resources located along the coastline. Few intact native coastal and lowland plant communities remain in Hawai‘i. Many of those that remain contain listed endangered species and provide important habitat...
Monitoring Hawaiian Biodiversity: Changes to forest birds and their habitat
Hawaiian forests are beset by many stressors, resulting in a complex pattern of altered ecosystems, impeirled species, and (in some areas) substantial protection and restoration. Short-term studies focused on specific sites or biota have limited value in understanding landscape-level change. Long-term and spatialy extensive data are needed to understand how ecosystems are reacting to both stressor...

National seed strategy progress report, 2015-2020
Native plants are the true green infrastructure we rely on for healthy, resilient, and biodiverse ecosystems. They protect us against climate change and natural disasters; create habitat for wildlife, rare species, and pollinators; and are vital for carbon sequestration. Without native plants, especially their seeds, we do not have the ability to restore functional ecosystems after natural disaste

Biotic and abiotic treatments as a bet-hedging approach to restoring plant communities and soil functions
Two related concepts in restoration ecology include the relative interchangeability of biotic and abiotic restoration treatments for initiating recovery and bet hedging using multiple restoration approaches to increase the likelihood of favorable restoration outcomes. We used these concepts as a framework to implement a factorial experiment including biotic (outplanting greenhouse-grown individual

Hawai‘i forest review: Synthesizing the ecology, evolution, and conservation of a model system
As the most remote archipelago in the world, the Hawaiian Islands are home to a highly endemic and disharmonic biota that has fascinated biologists for centuries. Forests are the dominant terrestrial biome in Hawai‘i, spanning complex, heterogeneous climates across substrates that vary tremendously in age, soil structure, and nutrient availability. Species richness is low in Hawaiian forests compa

Distributions of native and invasive Typha (cattail) throughout the Prairie Pothole Region of North America
The Prairie Pothole Region (PPR) of North America has experienced extreme changes in wetland habitat due to proliferation of invasive plants. Typha × glauca is a highly competitive hybrid between native T. latifolia and non-native T. angustifolia, and it is likely the predominant taxon in PPR wetlands. Genetics-based studies are limited, and distributions are poorly known for the first-generation

Cloud water interception in Hawai‘i: Developing capacity to characterize the spatial patterns and effects on water and ecological processes responses in Hawai‘i
Cloud-water interception (CWI) is the process by which fog or cloud water droplets are captured and accumulate on the leaves and branches of plants, some of which drips to the ground. Prior studies in Hawai'i indicate that CWI is highly variable and can contribute substantially to total precipitation. In this study, we monitored CWI and other processes at five mountain field sites on the Islands o

Seasonal impoundment alters patterns of tidal wetland plant diversity across spatial scales
Understanding patterns of biodiversity is a key goal of ecology and is especially pressing in the current human‐caused biodiversity crisis. In wetland ecosystems, human impacts are centered around hydrologic manipulation including the common practice of wetland diking and impoundment. Constraining how wetland management influences plant biodiversity patterns across spatial scales will provide info

Freezing temperatures restrict woody plant recruitment and restoration efforts in abandoned montane pastures
Tropical montane forests are being lost at an alarming rate but harbor some of the globe’s most unique biodiversity. The Hawaiian archipelago is a prime example of the importance of high elevation forests to species conservation and persistence as they serve as the last refugia for Hawaiian birds. Yet these forests have been converted to invasive dominated pastures, and efforts to restore them hav

Post-fire vegetation response in a repeatedly burned low-elevation sagebrush steppe protected area provides insights about resilience and invasion resistance
Sagebrush steppe ecosystems are threatened by human land-use legacies, biological invasions, and altered fire and climate dynamics. Steppe protected areas are therefore of heightened conservation importance but are few and vulnerable to the same impacts broadly affecting sagebrush steppe. To address this problem, sagebrush steppe conservation science is increasingly emphasizing a focus on resilien

Riparian plant communities remain stable in response to a second cycle of Tamarix biocontrol defoliation
Reduced abundance of non-native Tamarix shrubs in western U.S. riparian systems following biological control by a defoliating beetle has led to concerns that replacement plant communities could be dominated by other invasive species and/or not provide some of the ecosystem services that Tamarix was providing. In previous studies, Tamarix decline following biocontrol was accompanied by small increa
