Lori Randall
Lori Randall is a biologist at the Wetland and Aquatic Research Center in Lafayette, LA.
Randall's current research focuses on studies of bird-habitat relations that include the use of weather radar to determine landscape-scale habitat needs of migrating and wintering birds. Previous research focused on the effects of nutria herbivory on primary production and plant stand structure in Gulf Coast wetlands.

Use of Remote Sensing Data to Quantify Bird and Bat Distributions and Inform Migratory Bird Conservation Efforts
Three federal wildlife refuge complexes on the upper Texas coast include portions of the Columbia Bottomlands and other forests that are important for migratory birds and possibly bats: Texas Mid-Coast, Trinity River, and Chenier Plain.
Use of Remote Sensing Data to Quantify Bird Distributions and Aid in the Environmental Assessment of Energy Development in the Gulf of Mexico Region
Knowing where migratory birds consistently stop to rest and forage is critical for conservation planning, particularly along the northern and western Gulf where there is increased interest in energy development.
Habitat use and trends of landbirds using National Wildlife Refuges along the northern Gulf of Mexico during migration
This data release includes measures of vertically-integrated reflectivity (VIR) and estimates of linear trends in VIR as observed by the Weather Surveillance Radar 1988 Doppler (WSR-88D) stations along the Gulf of Mexico during spring and autumn migrations from 2018-2020. The VIR is a measure of bird density and can be used to map the spatial distribution of birds as they leave stopover habitat an

GoMAMN Strategic Bird Monitoring Guidelines: Landbirds
Landbirds in the Gulf of Mexico region include an ecologically diverse group of taxa that depend on a wide range of terrestrial habitats and the airspace above them. For the GoMAMN region of the Gulf of Mexico, the Landbird Working Group identified 19 species from 12 families as priorities for monitoring (Table 3.1). In addition, all species that stopover within the GoMAMN region during migration

Linking animals aloft with the terrestrial landscape
Despite using the aerosphere for many facets of their life, most flying animals (i.e., birds, bats, some insects) are still bound to terrestrial habitats for resting, feeding, and reproduction. Comprehensive broad-scale observations by weather surveillance radars of animals as they leave terrestrial habitats for migration or feeding flights can be used to map their terrestrial distributions either

Assessment of bird response to the Migratory Bird Habitat Initiative using weather-surveillance radar
In response to the Deepwater Horizon oil spill in spring 2010, the Natural Resources Conservation Service implemented the Migratory Bird Habitat Initiative (MBHI) to provide temporary wetland habitat for migrating and wintering waterfowl, shorebirds, and other birds along the northern Gulf of Mexico via managed flooding of agricultural lands. We used weather-surveillance radar to conduct broad reg

Application of ground-truth for classification and quantification of bird movements on migratory bird habitat initiative sites in southwest Louisiana: final report
This project was initiated to assess migrating and wintering bird use of lands
enrolled in the Natural Resources Conservation Service’s (NRCS) Migratory Bird Habitat
Initiative (MBHI). The MBHI program was developed in response to the Deepwater
Horizon oil spill in 2010, with the goal of improving/creating habitat for waterbirds
affected by the spill. In collaboration with the University of De

Wintering waterfowl respond to Wetlands Reserve Program lands in the Central Valley of California
Daytime use by wintering waterfowl at Wetlands Reserve Program (WRP) sites within the northern Central Valley of California (CVC) increased dramatically after wetland restoration and was sustained for up to 8 years post-restoration. The magnitude of the increase in waterfowl density at WRP sites after wetland restoration was greater with greater densities of birds in the local area before restorat

Mapping wintering waterfowl distributions using weather surveillance radar
The current network of weather surveillance radars within the United States readily detects flying birds and has proven to be a useful remote-sensing tool for ornithological study. Radar reflectivity measures serve as an index to bird density and have been used to quantitatively map landbird distributions during migratory stopover by sampling birds aloft at the onset of nocturnal migratory flights

Potential use of weather radar to study movements of wintering waterfowl
To protect and restore wintering waterfowl habitat, managers require knowledge of routine wintering waterfowl movements and habitat use. During preliminary screening of Doppler weather radar data we observed biological movements consistent with routine foraging flights of wintering waterfowl known to occur near Lacassine National Wildlife Refuge (NWR), Louisiana. During the winters of 2004–2005 an

Understanding interaction effects of climate change and fire management on bird distributions through combined process and habitat models
Avian conservation efforts must account for changes in vegetation composition and structure associated with climate change. We modeled vegetation change and the probability of occurrence of birds to project changes in winter bird distributions associated with climate change and fire management in the northern Chihuahuan Desert (southwestern U.S.A.). We simulated vegetation change in a process-base

Assessing conservation relevance of organism-environment relations using predicted changes in response variables
1. Organism–environment models are used widely in conservation. The degree to which they are useful for informing conservation decisions – the conservation relevance of these relations – is important because lack of relevance may lead to misapplication of scarce conservation resources or failure to resolve important conservation dilemmas. Even when models perform well based on model fit and predic
