This study will examine effects of different levels of nitrogen fertilizer on plant communities and soil processes in the park. Carlsbad Caverns National Park, Jennifer Holguin It’s Alive! Biological Soil Crusts of the Sonoran and Chihuahuan Deserts It might come as a surprise to learn that in the sublime expanses of the Sonoran and Chihuahuan deserts, some of the most interesting life around can be found in the dirt right in front of your feet! Biological soil crusts form a living groundcover that is the foundation of desert plant life. Soil crust at White Sands National Monument Morale, Welfare and Recreation in WWII National Parks Wartime NPS Director Newton Drury wrote 'In wartime, the best function of these areas is to prove a place to which members of the armed forces and civilians may retire to restore shattered nerves and to recuperate physically and mentally for the war tasks still ahead of them.' During World War II, parks across the United States supported the morale of troops and sought to become places of healing for those returning from war.

The next day, the fire crossed into Carlsbad Caverns NP, and Pecos Zone Type III Team took over management of the fire. Fire crews from various partner agencies used existing roads, trails, and fire scars to help keep the fire in check and conducted multiple burnout operations to tie in and strengthen containment lines. Air Quality Monitoring in the Southern Plains and Chihuahuan Desert Networks Both the Clean Air Act and the National Park Service Organic Act protect air resources in national parks. Park resources affected by air quality include scenery and vistas, vegetation, water, and wildlife. Over the past three decades, the National Park Service has developed several internal and cooperative programs for monitoring various measures of air quality. Cactus and clear skies at Tonto National Monument Air Quality in the Chihuahuan Desert Three park units in the Chihuahuan Desert Network, Big Bend National Park (NP), Carlsbad Caverns NP, and Guadalupe Mountains NP are designated as Class I air quality areas under the Clean Air Act. Class I areas receive the highest protection under the act, and degradation of air quality must be minimal. Air quality concerns include atmospheric deposition effects and visibility impairment from fine particle haze. Rugged landscape under a partly cloudy sky at Big Bend National Park Monitoring Upland Vegetation and Soils in the Sonoran Desert and Chihuahuan Desert Networks Vegetation and soils are two of many natural resources monitored by the National Park Service (NPS) Division of Inventory & Monitoring (I&M). Learning about vegetation dynamics helps us to better understand the integrity of ecological processes, productivity trends, and ecosystem interactions that can otherwise be difficult to monitor. In NPS units of the American Southwest, three I&M networks monitor vegetation and soils using the scientific protocol described here.

Exotic Plants Monitoring in the Southern Plains and Chihuahuan Desert National parks, like other publicly managed lands, are deluged by new exotic species arriving through predictable (e.g., road, trail, and riparian corridors), sudden (e.g., long distance dispersal through cargo containers and air freight), and unexpected anthropogenic pathways (e.g., weed seeds mixed in with restoration planting mixes). Landscape with a uniform, green foreground consisting of invasive kochia Bats in Caves Bats and caves go together in people's minds. National Parks are home to many important bat caves. But, bats are particular. Many caves only contain a few bats. Some bats like certain caves for raising their young and other caves for winter hibernation. Other bats avoid caves entirely and sleep and raise their young in protected locations in trees and rocks outside. a group of bats hanging on a cave ceiling Student Journal: Studying the Air at Carlsbad Caverns National Park Student intern Jeremy McClung shares his experience learning about and assisting with an air quality study at Carlsbad Caverns National Park. Kings palace cave formations in carlsbad caverns national park Cave Exploration in the National Parks Most Americans may not realize that their National Park caves lie at the forefront of on-going cave exploration. Some of the longest caves on Earth are managed and protected by the NPS. And all of these caves contain unexplored passages and rooms that cavers seek to find and document. These giant cave systems are the site of on-going work by cavers to explore, map, photograph and inventory the extent of National Park caves. delicate thin mineral formations in a cave An Inventory of Fossils at Carlsbad Caverns National Park The rich fossil record at Carlsbad Caverns National Park, New Mexico, was the focus of a recent paleontological resource inventory.

Climate data help scientists to understand ecosystem processes and help to explain many of the patterns and trends observed in other natural-resource monitoring. In NPS units of the American Southwest, three I&M networks monitor climate using the scientific protocol described here. Kayaking across a fl ooded parking lot, Chickasaw NRA, July 2007. Climate Monitoring at Carlsbad Caverns National Park Climate is the primary driver of ecological processes on earth. A broader time scale (seasons to years) is what distinguishes climate from the instantaneous conditions reflected by the term weather. We conduct long-term climate monitoring to detect climate changes that could have cascading effects on park ecosystems.

After a promising start in the early 1920s, only a handful of women were hired as park rangers and naturalists in the late 1920s and early 1930s. Carlsbad Caverns National Park and the national monuments of the Southwest became the new hot spots for women in uniformed positions in the 1930s. Women in skirts and pants Changing Clothes By the end of the 1930s, skirts were the common exemption to the standard uniform for women. As they ditched the breeches, they also lost their iconic Stetson hats. Women wanted more comfortable, better fitting, and more flattering uniforms. Many of the details of how changes came about are fuzzy, and it seems that the first separate women’s uniform adopted in 1941 was never implemented. Guide Olive Johnson at Carlsbad Caverns is wearing the WAC-style jacket at Carlsbad Caverns, Substitute Rangers As the 1940s dawned, the United States was still dealing with the economic woes of the Great Depression and trying not to get drawn in WWII. Even as it continued to manage New Deal Program work in national and state parks, the NPS remained understaffed as a government bureau. The emergency relief workers and about 15 percent of NPS staff enlisted or were drafted during the first couple of years of WWII. Winifred Tada, 1940.

Potential Future Uses for Laser Scanning Data Collected in Carlsbad Caverns The cultural landscape of Carlsbed Caverns National Park consists of the built environment within the cave, as well as above. Terrestrial laser scanning (TLS) data has allowed creative analysis, precise measurements, maneuvering through and understanding complex and challenging landscapes, and pushing the boundaries of cultural landscape analysis and documentation. Erin Gearty describes how 3D data can be used for resource protection. Laser Scanning in Carlsbad Caverns "Digital 3D documentation of the portions of Carlsbad Caverns National Park which had the highest degree of cultural contact was performed. My initial walk through of the cave several months prior to the actual work, my repeated comment was, 'This is really big.' This rather apparent observation did drive quite a few of the decisions we had to make doing this project." --- Malcolm Williamson A render of point cloud data showing trails through the caverns. Introduction: Use of 3D Data in Carlsbad Caverns This was a mitigation project for damage done inside of Carlsbad Caverns National Park by park staff that predates everyone at that park right now...And our conversations were about how to document the cave well, document it how we needed it documented to do a cultural landscapes inventory (CLI) how we could then use that information to take care of these resources inside the cave going forward. Julie McGilvray, National Park Service, at a lectern giving a presentation. Using 3D Documentation to Create 2D Maps of Carlsbad Caverns Kimball Erdman discusses how to use point cloud data and apply it in terms of a cultural landscape inventory. This is the first time a subterranean cultural landscape has been digitized in such a fashion. Erdman has performed digital landscape reconstructions for the Buffalo National River, and on a much larger scale, on Japanese internment camps. Kimball Erdman discusses how to use point cloud data in a cultural landscape inventory. Creating a Repeatable Method for Viewshed Analysis Using Lidar Data in Carlsbad Caverns "Both the paved path and the lighting system that make the cave accessible to visitors are responses to its existing geometry...through this symbiosis of nature and design, in terms of the delta between what actually exists in the caverns...and what the visitor perceives there, by virtue of the design choices at play." --- Claire Gorman Claire Gorman, Yale University stands at a lectern during her presentation. Changing Patterns of Water Availability May Change Vegetation Composition in US National Parks Across the US, changes in water availability are altering which plants grow where. These changes are evident at a broad scale. But not all areas experience the same climate in the same way, even within the boundaries of a single national park. A new dataset gives park managers a valuable tool for understanding why vegetation has changed and how it might change in the future under different climate-change scenarios. Green, orange, and dead grey junipers in red soil, mountains in background Changing Attitudes Most women with disabilities hired by the National Park Service (NPS) in the 1970s and early 1980s had temporary jobs. Some built long-term careers with the bureau. Starting before the Americans with Disabilities Act of 1990, these women experienced the opportunities and changes the law brought. It was their hard work and dedication to the NPS mission, however, that continued to change attitudes and educate coworkers and visitors alike. Ranger Shirley Beccue in her wheelchair and NPS uniform and flat hat looks out over the Everglades. Ranger Roll Call, 1930-1939 Few women worked in uniformed positions in the 1930s but those who did weren't only ranger-checkers or ranger-naturalists. Jobs as guides, historians, archeologists, and in museums opened to more women. Seven women in Park Service uniforms stand in line inside a cave. Ranger Roll Call, 1940-1949 Only a small number of women held temporary ranger positions in national parks during World War II. Carlsbad Caverns National Park, national monuments in the Southwest, and historical sites in the East continued to employ more women. Although a few women veterans benefitted from post-war veteran hiring programs, most veterans were men and permanent positions became even more difficult for women to get. Catherine Byrnes and Barbara Dickinson stand outside modeling the NPS uniform. Ranger Roll Call, 1950-1959 In the 1950s, women in uniform continue to work as guides, historians, and archeologists. Few women had permanent positions. A handful of women began to get seasonal ranger-naturalists positions at large national parks for the first time in two decades.

Studying the Past and Predicting the Future Using Rat Nests In the western United States, packrat middens are one of the best tools for reconstructing recent environments and climates. These accumulations of plant fragments, small vertebrate remains, rodent droppings, and other fossils can be preserved for more than 50,000 years. Packrat middens have been found in at least 41 National Park Service units. Photo of a wood rat.
