Question: What type of movie does The Living Desert and The Saved have in common?

Context paragraphs:
True-Life Adventures: True-Life Adventures series is a collection of fourteen full length and short subject documentary films produced by Walt Disney Productions roughly between the years 1948 and 1960.  The series won eight Academy Awards for the studio including three Academy Award for Best Documentary Feature awards for "The Living Desert", "The Vanishing Prairie" and "White Wilderness", and five Best Two Reel Live Action Short awards for "Seal Island", "In Beaver Valley", "Nature's Half Acre", "Water Birds", and "Bear Country".  It inspired a daily panel comic strip that was distributed from 1955 to 1971 and drawn by George Wheeler.  Several of the films were adapted in comic book format as one shots in the Dell Comics Four Color series.  The films were among the earliest production experience for Roy E. Disney.  Also this film series was the launching pad for Disney's new distributor, Buena Vista International.  TV episodes are from Disney's anthology TV series.

Norman R. Palmer: Norman Palmer (October 7, 1918 - March 23, 2013) was an American Disney television editor.  Palmer worked for Disney for around 45 years and served as a mentor to Roy Disney, who was appointed vice-chairman of Disney productions.  Palmer was born and raised in California and graduated from Hollywood High School in 1937.  He joined the editorial division of Disney in 1940.  Palmer edited films including The Living Desert, The African Lion, Water Birds, The Shaggy D.A., and The Legend of Lobo.  He died on March 23, 2013, of natural causes.

Desert dry wash: Desert dry wash is a North American desert vegetation type (or biome) occurring in the flat bottoms of canyons and drainages that lack water at or near the surface most of the year, and are subject to periodic severe flooding events.  Desert dry wash is contrasted with desert riparian vegetation, which occurs in desert canyons and drainages where there is year-round water at or near the surface.  Plants must either be able to survive the severe flooding conditions or be able to reestablish themselves before the next flooding event.  Some of these plants have evolved so that in order for their seeds to germinate, the seeds must be scarified or abraded by tumbling sand, gravel, and rocks during the flooding event.  They must then quickly send down roots deep enough to be able to tap into deep underground water reserves, in order to survive the dry period after the flooding.  Common dominant species of the desert dry wash include smoke tree ("Psorothamnus spinosus"), desert willow ("Chilopsis linearis"), catclaw ("Senegalia greggii"), cheesebush ("Ambrosia salsola"), and waterweed ("Baccharis sergiloides").

Creosote bush scrub: Creosote bush scrub is a North American desert vegetation type (or biome) of sparsely but evenly spaced desert plants dominated by creosote bush ("Larrea tridentata") and its associates.  It's visual characterization is of widely spaced shrubs that are somewhat evenly distributed over flat or relatively flat desert areas that receive between 2 and 8 inches of rain each year.  It covers the majority of the flat desert floor and relatively flat alluvial fans in the Mojave Desert, Chihuahuan Desert, and Sonoran Desert.  The dominant plants that typify this vegetation type are creosote bush ("Larrea tridentata") and its associates, white bur-sage ("Ambrosia dumosa"), brittlebush ("Encelia farinosa", "Encelia actoni", "Encelia virginensis"), cheese-bush ("Ambrosia salsola"), Mojave yucca ("Yucca schidigera"), silver cholla cactus ("Cylindropuntia echinocarpa"), and beavertail cactus ("Opuntia basilaris").  Creosote bush has a wider range than its associates, so codominant shrubs, which are associated with more narrow ranges, will vary from region to region.

Living Desert Zoo and Gardens State Park: The Living Desert Zoo and Gardens State Park, formerly the Living Desert Zoological and Botanical State Park, is a zoo and botanical garden displaying plants and animals of the Chihuahuan Desert in their native habitats.  It is located off U.S. Route 285 at the north edge of Carlsbad, New Mexico, at an elevation of 3200 ft atop the Ocotillo Hills overlooking the city and the Pecos River.  It is open every day except Christmas.

The Saved: The Saved is a Dutch documentary released in 1998.  It was directed by Paul Cohen and Oeke Hoogendijk.

Desert riparian: Desert riparian is a North American desert vegetation type (or biome) occurring in the bottoms of canyons and drainages that have water at or near the surface most of the year.  It is contrasted with the desert dry wash vegetation type in which water at or near the surface is lacking most of the year.  The visual character is of large, lush green trees surrounded by dry desert vegetation and soil coloration.  The area may be in a patch surrounding a spring (oasis), or in a strand following the course of water flow.  Over 80% of known desert wildlife species use desert riparian areas.  Common dominant species include Fremont cottonwood ("Populus fremontii"), Arizona ash ("Fraxinus velutina"), arroyo willow ("Salix lasiolepis"), Goodding's willow ("Salix gooddingii"), red willow ("Salix laevigata"), California fan palm ("Washingtonia filifera"), and invasive species such as salt cedar ("Tamarix ramosissima"), giant reed ("Arundo donax"), and Russian olive ("Elaeagnus angustifolia").  Salt cedar is particularly causing problems for this ecosystem because it is able to extract water more efficiently than cottonwoods and willows.  Many noninvasive non-native species may also be found because springs and surface water areas in the desert often were old homesites where such species were intentionally planted, such as elm, black locust, and assorted fruit trees.

Pobiti Kamani: Pobiti Kamani (Bulgarian: Побити камъни , "planted stones"), also known as The Stone Desert, is a desert-like rock phenomenon located on the north west Varna Province border in Bulgaria.  It is considered the only desert in Bulgaria and one of few found in Europe.  The desert consists of sand dunes and several groups of natural rock formations on a total area of 13 km².  The formations are mainly stone columns between 5 and 7 meters high and from 0.3 to 3 meters thick.  The columns do not have solid foundations, but are instead hollow and filled with sand, and look as if they were stuck into the surrounding sand, which gives the phenomenon its name.  Sandstorms and sand twisters have also been known to commonly occur in this desert region of Bulgaria.  The Stone Desert is not only a well known European tourist attraction due to its desert like habitat, but it is one of few places where desert type vegetation such as cactus are known to grow.  It is also the only desert in Europe in which desert reptilians and other desert type animalia are found to thrive.  The Stone Desert along with the Tabernas Desert of Spain is one of two naturally formed deserts in all of Europe and the only known naturally formed desert in Eastern Europe.

The Living Desert: The Living Desert is a 1953 American nature documentary film that shows the everyday lives of the animals of the desert of the Southwestern United States.  The movie was written by James Algar, Winston Hibler, Jack Moffitt (uncredited) and Ted Sears.  It was directed by Algar, with Hibler as the narrator and was filmed in Tucson, Arizona.  The film won the 1953 Academy Award for Best Documentary Feature.

Living Desert Zoo and Gardens: Living Desert Zoo and Gardens, formerly the Living Desert Museum, is a desert botanical garden and a zoo located in Palm Desert, Riverside County, California, United States.  They are in the Sonoran Desert of the Coachella Valley and Santa Rosa Mountains foothills near Palm Springs, California.
