Southern Cattail (Typha domingensis)

Commonly found in the southern half of the United Stats, the Southern Cattail ( Typha domingensis ) is a a wetland plant which may be found in California, Nevada and Arizona. The Southern Cattail will flower in late spring and summer and produces a densely packed seed spike which may grow up to 13 inches long. The Pistillate spike is the identifying feature on this wetland plant.

This rhizomatous plant is centered around a simple, erect stem which may grow between 5 and 13 feet tall. Each stem may grow between 6 and 9 long and linear leaves. As with many marsh plants, the cattail has an internal tissue adaptation which allows the direct transfer of air between the leaves and roots, which is similar to a vegetative snorkel. The hot dog shaped brown flower is indicative of a female plant, while the male is characterized by a yellowish tapered cone arrangement.

The cattail is typically found between sea level and 6000 feet in elevation. Native American tries were known to use the plant as thatch, and the young shoots could be utilized as a food source. The seed fluff could also be mixed with tallow and chewed as a gum.

Recent studies suggest that the Typha is very effective at cleaning the water of bacterial contamination. This includes up to 90% reduction of enterobacteria which is common flora inside of mammalia intestines.

Indian Paintbrush (Castilleja miniata)

The Giant Red Indian Paintbrush or Indian Paintbrush (Castilleja miniata) is a wildflower and perennial which is quite common in the western United States, including California, Nevada and Utah. The genus Castilleja contains about 200 species of hemiparasitic wildlowers.

The plant is known to grow between 1.5 and 3 feet tall and their stems may be unbranded of semi-branched. The flower cluster of the plant is said to resemble a paintbrush which gives the plant its common name. The bracts beneath the flower are known to be brightly colored and may be a bright orange, pink or a crimson red. Typically the paint brush will bloom May through Sepetember, however this event is subject to environmental conditions such as altitude and water availability.

The paint brush generally prefers sunlight and moist well drained soils. The root system will connect with and grow into the root system of other planets to harvest nutrients from the host plant. For this reason, they are no able to be transplanted easily.

Native American tribes are known to consume the edible flowers of the paintbrush. The selenium rich flowers were also used as a hair wash by the Ojibwe people. The Owls Clover is a member of the same genus as the Indian Paintbrush.

Mustang (Equus ferus caballus)

The Wild Mustang (Equus caballus), an enduring symbol of the American frontier, roams the vast, arid expanses of the desert southwest United States as a feral horse population descended from domesticated Spanish horses introduced in the 16th century. These hardy equines, often romanticized in folklore and media, have adapted through natural selection to survive in harsh environments, exhibiting remarkable resilience amid sparse resources and extreme conditions. With populations managed by the U.S. Bureau of Land Management (BLM) to balance ecological sustainability, mustangs embody a complex interplay of history, biology, and conservation in regions like Nevada, Arizona, and New Mexico.

Classification

The Wild Mustang is classified within the kingdom Animalia, phylum Chordata, class Mammalia, order Perissodactyla, family Equidae, genus Equus, and species caballus. Though often referred to as “wild,” mustangs are technically feral horses, descendants of domesticated equines rather than a truly wild subspecies like the extinct North American horses that evolved on the continent millions of years ago. Their ancestry traces primarily to Colonial Spanish horses from the Iberian Peninsula, with mitochondrial DNA studies confirming high frequencies of Iberian haplotypes, though admixtures from other breeds like Thoroughbreds, Quarter Horses, and drafts have occurred over time. Distinct strains, such as the Spanish Mustang or Kiger Mustang, retain stronger Spanish bloodlines, while isolated herds in the desert southwest may exhibit unique genetic traits shaped by geographic separation and natural selection.

Physical Description

Mustangs are compact, medium-sized horses, typically standing 14 to 15 hands high (56 to 60 inches or 142 to 152 cm at the withers) and weighing around 800 pounds (360 kg). They possess a light-riding build with muscular bodies, strong bone structure, and exceptional hardiness, featuring flat or slightly convex head profiles, broad foreheads tapering to fine muzzles, and eyes set slightly higher on the face. Necks are well-defined and attach smoothly to sloping shoulders, with moderately narrow chests, short strong backs, deep heart girths, well-sprung ribs, and smooth round hindquarters. Legs are straight and sound, supported by durable hooves with thick walls, ideal for rugged terrain. Coat colors vary widely, including bay, sorrel, dun, appaloosa, paint patterns, and primitive markings like stripes, though some registries exclude certain patterns like tobiano. Movement is smooth and rhythmic, with the ability to gallop at 25–30 mph (40–48 km/h), and up to 55 mph (88 km/h) in short bursts. In the desert southwest, natural selection favors traits like surefootedness, endurance, and agility for navigating arid landscapes.

Behavior

Wild mustangs are social animals that form structured groups known as bands or herds, typically comprising one dominant stallion (over 6 years old), around eight mares, and their young, led by a head mare who guides the group to safety in threats while the stallion defends from behind. Stallion leadership is dynamic, with challenges from rivals promoting genetic diversity. Communication relies on body language, such as ear positioning, tail swishing, and vocalizations, to convey emotions and maintain hierarchy. They exhibit intelligence, curiosity, and a strong fight-or-flight response honed by survival in harsh environments, making them cautious yet resilient. In the desert southwest, mustangs travel long distances for resources, adapting foraging strategies and mixing with other herds during dangers. Isolated populations may show unique behaviors, like gaited movements or curly coats in Nevada herds, influenced by genetic admixtures. Without significant predators, populations can grow rapidly, leading to overgrazing if unmanaged.

Food Sources

As herbivores and hindgut fermenters, mustangs primarily consume grasses, brush, shrubs, and other native vegetation, extracting nutrients from low-quality forage via their cecum—a adaptation allowing survival in arid regions where ruminants like cattle struggle. In the desert southwest, they graze close to the ground on sparse plants, ranging 5–10 times farther than cattle to access food and water, often digging for hydration in dry areas. Their diet requires about 1.5 animal units (AUM) of forage, focusing on soluble fiber while avoiding excess sugars to prevent digestive issues. An average mustang needs around 16 pounds of grass daily, supplemented by minerals and salts in harsh environments. This opportunistic foraging supports their easy-keeper nature, enabling them to thrive on limited resources in deserts and grasslands.

Breeding

Mustangs are viviparous, with mares carrying foals for an 11-month gestation period, typically giving birth in spring (April to June) to align with milder weather and abundant forage for growth. Breeding occurs within isolated herds, where dominant stallions mate with mares, and dynamic challenges ensure genetic diversity, though inbreeding in small populations can lead to issues like reduced heterozygosity and diseases such as PSSM Type 1. Unmanaged herds can grow by up to 20% annually, prompting BLM interventions like fertility control to prevent overpopulation and starvation. Foals are born precocial, able to stand and nurse shortly after birth, and remain with the herd for protection. In the desert southwest, breeding success ties to resource availability, with natural selection favoring resilient offspring in arid conditions. Lifespans in the wild reach up to 36 years, shorter than in captivity.

Habitat and Range

Wild mustangs inhabit arid and semiarid public rangelands west of the Continental Divide, including deserts, grasslands, and mountainous terrains, where they adapt to extreme temperatures, scarce water, and sparse vegetation. In the desert southwest United States, populations thrive in states like Nevada (hosting over half of North America’s free-roaming mustangs), Arizona, New Mexico, Utah, and California, managed across 26.9 million acres in Herd Management Areas (HMAs) by the BLM. These areas encompass ecosystems from the Great Basin to the Colorado Plateau, with herds digging for water and migrating seasonally for forage. Total free-roaming numbers exceed 72,000, protected under the 1971 Wild Free-Roaming Horses and Burros Act as living symbols of the West, though overpopulation challenges lead to roundups and adoptions.

Barrel Cactus (Ferocactus cylindraceus)

The Barrel Cactus (Ferocactus cylindraceus) is a commonly seen resident of the desert southwest and its range includes California, Nevada, Utah and New Mexico. The cactus gets its name from its short stocky appearance which is said to resemble a barrel. Despite its name, this succulent can grow over 6 feet tall and thrives in gravelly, rocky and / or sandy soils and are typically seen below 5000 feet in elevation.

The succulent is covered in spines which when new, are straight and red in appearance, and will turn gray in color and curve as they age. This species blooms yellow or red flowers on the top of the plant, which typically happens in the spring. Like its name sake, this desert nomad will swell with fluid during the monsoons to survive the long dry periods of the desert heat.

Some Native Americans utilized this plant as a cooking vessel. It is said that they would remove the top of the plant and remove the pulp from the interior. Hot stones were place inside along with the food. Additionally, the long heavy spins were utilized as needles.

There are fifteen different species of this cactus.

As the name implies, the California Poppy is that state flower of California. However, this little flower is extremely wide spread and flourishes throughout most of the United States. The flower was first described by a Germain naturalist and poet, Adelbert von Chamisso. Chamisso was travelling on the Russian exploring ship “Rurick”. The “Rurick” was travelling around in the world in 1815, when the ship sailed in the San Francisco Bar Area.

This species of flowering plant with an international pedigree is a perennial and can range in height from 5 – 60 inches. The four petals of the flower are about two inches in size and range in colors from a vibrant orange to yellow, red and in some cases pink. They typically flower between February and September depending upon location.
