The Habitat Management Plan details how threatened and endangered species and their habitats are managed at LANL.

Endangered species on laboratory land

The Habitat Management Plan (pdf) details how threatened and endangered species and their habitats are managed at LANL. The Plan consists of site plans for federally listed threatened or endangered species with a moderate or high probability of occurring at the Laboratory.

The following federally listed threatened or endangered species currently have site plans at LANL:

  • Mexican spotted owl (Strix occidentalis lucida)
  • Southwestern willow flycatcher (Empidonax trailii extimus)

Mexican Spotted Owl

The Mexican spotted owl is the only subspecies of spotted owl recognized in New Mexico and generally inhabits mixed conifer and ponderosa pine forests in mountains and canyons. A mated pair of adult spotted owls may use the same home range and general nesting areas throughout their lives.

The Mexican spotted owl was listed as “threatened” under the Endangered Species Act in 1993. At LANL there are presently five areas of environmental interest comprised of Mexican spotted owl habitat.

The primary threats to Mexican spotted owl on LANL property are impacts on habitat quality from LANL operations and disturbance of nesting spotted owls.

Learn more about the Southwestern Willow Flycatcher
Southwestern Willow Flycatcher

The Southwestern willow flycatcher breeds only in dense riparian habitats in the southwestern United States. In New Mexico, the species is found primarily along the Gila River and Rio Grande drainages. It is vulnerable to the loss, fragmentation, and modification of riparian breeding habitat, including the removal of exotic vegetation along the Rio Grande, where nesting in salt cedar is a regular occurrence.

The southwestern willow flycatcher was listed as “endangered” under the Endangered Species Act in 1995.

At LANL, there is one area managed as southwestern willow flycatcher habitat under the Habitat Management Plan.

Innovations for a secure nation

Novel rocket design flight tested

Novel rocket design flight tested

The new rocket fuel and motor design adds a higher degree of safety by separating the fuel from the oxidizer, both novel formulations that are, by themselves, not able to detonate.
