Baja California Animal and Plant Species
Animal Species: Leatherback Sea Turtle (Dermochelys Coriacea) The largest of all living turtles and is the fourth-heaviest modern reptile behind three crocodiles. It is the only living species in the genus Dermochelys and family Dermochelyidae. It can easily be differentiated from other modern sea turtles by its lack of a bony shell, hence the name. Instead, its carapace is covered by skin and oily flesh. Cultural Significance: The Seri people, a tribe found in Mexico, find the leatherback sea turtle of significant cultural significance because it is one of their five main creators. The Seri people devote ceremonies and fiestas to the turtle when one is caught and then released back into the environment. Ecological Trouble: Leatherbacks have slightly fewer human-related threats than other sea turtle species. Their flesh contains too much oil and fat to be considered palatable, reducing the demand. However, human activity still endangers leatherback turtles in direct and indirect ways. Directly, a few are caught for their meat by subsistence fisheries. Nests are raided by humans in places such as Southeast Asia. In the state of Florida, there have been 603 leatherback strandings between 1980 and 2014. Almost one-quarter (23.5%) of leatherback strandings are due to vessel-strike injuries, which is the highest cause of strandings.

The Seri people have noticed the drastic decline in turtle populations over the years and created a conservation movement to help this. The group, made up of both youth and elders from the tribe, is called Grupo Tortuguero Comaac. They use both traditional ecological knowledge and Western technology to help manage the turtle populations and protect the turtle's natural environment.

Plant Species: Desert Fig Tree (Ficus Palmeri) Baja California has two native species of figs from the Moraceae Family: Ficus Palmeri, which grows from the Cape Region to the Tinaja de Yubay region, in Central Baja, many of the islands, and parts of Sonora; whereas, Ficus brandegeei has a smaller range from the Cape to a little north of Loreto, only. They are both pretty similar, with the largest difference being that the Ficus Palmeri does not display its branches and leaves with long ¨hairs¨, meanwhile the Ficus brandegeei does. Both varieties are called Higuera ("Fig" in Spanish), Zalate or Amate ("you love you" in Spanish), or the Desert Fig in English. Ecological Significance:

The Baja Ficus grows usually on cliffs or in the cracks of rocks. Trees and plants such as the Ficus, help to breakdown or weather stone, creating soil in its wake. Ficus palmeri, as well as three species of cacti in the Baja region (Pachycereus pringlei, Stenocerueus thurberi, and Opuntia cholla) feed on dense layers of microscopic bacteria and fungus that cover the rock surfaces. Then release valuable minerals such as potassium, zinc, magnesium, copper, iron, manganese, and phosphorus during this chemical weathering process. This process provides an indispensable supply of inorganic nutrients for other plants that do grow in the soil.

In Baja, a tea made from the leaves and small branches is used as an antidote for rattlesnake bites in cattle and mules. A wash is used to treat cuts and infections. This is probably due to the facts that the milky white sap of this tree is natural latex that is toxic, a known allergen and is photosensitive. It is also shown to contain anti-inflammatory and antiseptic chemicals as well. Desert Fig Tree

Animal Species: Vaquita (Phocoena sinus) This wonderful aquatic creature named Vaquita is under the Porpoises family which is a long group of marine animals that are mammals that are classified as Phocoenidae. Also the Vaquita, is an endemic animal, that is to say relevant of its location that receives its name “ Vaquita” which in Spanish means “little cow”. This species appears in the Gulf of Baja California and unfortunately is in danger of extinction. Cultural Significance: The Vaquita is one of the few species of the porpoise endemic which means that it exists only one place in the planet. Because of this it can bring many tourists in the area for ecotourism which is environmental tourism that sees wildlife in its habitat. But because unfortunately the Vaquita is in danger of extinction it can negatively affect the cultural aspect of the areas surrounding the Gulf of Mexico. Ecological Trouble: Unfortunately, the Vaquita is in danger to extinction. Because of this there will be fewer animals for both prey and predators many sea creatures will be affected by this in which the balance of the food chain in the Gulf of Mexico will have to change and adapt with the disappearance of this wonderful aquatic creature. Vaquitas usually eat around a dozen different type of small and medium sized fish in which will have one less predator so their numbers can grow and affect the food chain their and also other larger species such as sharks were the Vaquita’s predator in which they will have one less food source again negatively affecting the food chain.

Plant species: Ocotillo (Fouquieria splendens) This unique plant named the Ocotillo also known as a Fouquieria Splendens is a tall, greyish/greenish spiky plant from the Plantae family. This plant isn't considered a true cactus even though it is covered in thorns and is ingenious to both the Sonoran Desert and the Chihuahuan Desert. Cultural Significance: The Ocotillo does flower but only when it rains and when the flower dries it can be collected and used for tisanes which is an herbal tea. Also, Native American use to use to cut off the flowers when they blossomed and also cut of parts of the root and collect them for when someone in the tribe use to get cut they would apply either the root or the flower on the open cut which slowed down the bleeding. Ecological Significance: Both White-Tailed deer and Mule deer have the Ocotillo in their diet, but white-tail deer tends to eat much more Ocotillo than the Mule deer. Because the Ocotillo does flower both hummingbirds and native carpenter bees are able to get nectar from them which also helps the Ocotillo spread its pollen. Also, it can provide some cover or shelter from the hot desert for smaller mammals, birds and reptiles.

Ctenosaura hemilopha
This animal is also known as the cape spinytail iguana. They are reptiles that eat mostly plants but they are also able to eat small animals and bugs if they are present. They live in trees, build dens, and sometimes even in cacti. Some people believe that they are in the locations they are today because the Seri Indian people brought them as a source of food. These animals are considered vulnerable because humans are taking over their natural habitat. What I think is most surprising about these animals is that they coexist with another type of iguana which is not always common since there may be a limited amount of resources.

Agave shawii
This plant is also known as Shaw's agave or coastal agave. These plants which are part of the genus agave are drought resistant which makes them great for living in the desert. Their roots respond fast to rain which is a good adaptation for life in the desert. These plants were used by Kumeyaay Native Americans as a source of food, tools, and even clothing. They would make many things by beating the leaves which would result in fibers that they would use for rope, clothing, traps, sandals and many other things.

Antilocapra Americana Peninsularis Antilocapra americana peninsularis, also known as the Baja California pronghorn, is a subspecies of pronghorn endemic to the Baja California Peninsula. Antilocapra americana peninsularis is a critically endangered subspecies according to the IUCN with only an estimated 200 animals remaining in the wild. This subspecies can stand up to 35 inches tall at the shoulder and weigh in at up to 125 pounds. These animal's coloration ranges from golden brown to tan, with white coloration on the jaws, stomach, rump and lower neck. The Baja California Pronghorn is often called los fantasmas del desierto which translates to, “ghosts of the desert,” because their particular coloration in combination with their fast speeds allow them to disappear in the desert. Furthermore, these animal's white underbellies deflect ground heat, keeping them cool. Females are smaller than males, and if horned, retain their spike-like horns for 2-5 years before shedding them. The larger males are longer horned than females, with darker faces. Males' horns are forward-pointing prongs below backward-facing hooks, and outer sheaths are shed annually. These animals are known to live roughly 9-10 years in the wild but may live longer in captivity.

Range The Baja California pronghorn now only exists in the El Vizcaíno Desert Biosphere Reserve of Baja California and in the Valle de Los Cirios Reserve of Baja California, Mexico. The animals once roamed largely over central Baja California, including areas like the one east of Guerrero Negro named Llano del Berrendo, or Pronghorn Plains.

Cultural Significance Baja California pronghorn have long-standing ties as a source of sustenance to people indigenous to Baja California. The animals, once widespread, were hunted with bows and arrows, eaten, and skinned to make women’s clothing. The indigenous people, the Cochimí, referred to them as ammo-gokio or ammogokió.

Additional Information Antilocapra Americana Peninsularis is the fastest hoofed mammal in the world and the second-fastest land mammal. They possess the ability to run at 40-60 miles per hour for over an hour. With 27 foot strides at their top speeds, the Baja California Pronghorn has padded cloven hooves to absorb the resulting shock. When running these animals open their mouth and leave their tongue hanging to consume more air. Their windpipe can reach up to two inches in diameter, funneling air to their enlarged lungs and heart which aid them in oxygen consumption. This unique animal’s oxygen consumption is three times greater than that of comparably sized animals. Baja California Pronghorn have remarkable eyesight and have the largest eyes of any hoofed animal in North America their size. They have the ability to see for miles. Their pupils can constrict into horizontal slits, which gives them 300-degree vision, protecting them from predators.

Threats and Conservation The future for these animals remains uncertain. The International Union for Conservation of Nature lists their conservation status as critically endangered. Livestock fencing and cattle ranching threaten their livelihood. These obstructions inhibit the animal’s access to favorable habitats and their ability to conduct natural movement. Urban sprawl, human endeavor, and droughts also all threaten populations. In 1997, the Mexican Government, in cooperation with ENDESU (Espacios Naturales y Desarrollo Sustentable), established the Peninsular Pronghorn Recovery Project. This project, working in conjunction with zoos such as the Los Angeles' Zoo’s animal husbandry program, has grown the population of the Baja California Pronghorn to now exceed 420 animals, both captive and wild, in the areas of the El Vizcaíno Desert Biosphere Reserve and The Valle De Los Cirios Reserve.

Fouquieria Columnaris

Fouqueria Coumnaris, also often referred to as a Boojum tree or Cirio tree, is a nearly endemic species of stem succulent tree found in the Baja California Peninsula. These trees have a single or branched tapered primary stem. Their primary stems are armored with hundreds of horizontal secondary branches that are not succulents and are armed with spines. When moisture is available to the tree, leaves and secondary branches may grow. However, the trees are usually leafless during arid periods. In relation to moisture received during winter and spring months, the Boojum will elongate its stem. The Boojum is known to bloom in late summer and autumn, bearing clusters of white fragrant flowers or creamy yellow flowers with a honey scent. The tree is a member of the ocotillo family. The Boojum is reported to grow up to 70 feet tall, with its trunk growing up to 24cm thick.

Range Fouqueria Coumnaris is nearly endemic to the Baja California Peninsula. The tree grows with the help of moist, cool winds from the Pacific Ocean moderating the arid desert climate. The tree can be found in both upper and lower Baja, California. However, it is most commonly found in the subregion of Vizcaíno. Along the Gulf Coast of Sonora, a small population of Boojum exists with help from the cold waters that replicate the influence of the Pacific.

Name The plant received its English name from the Southwestern naturalist Godfrey Sykes in 1922. When Sykes encountered the foreign-looking plants, he dubbed them “boojums,” a nod to Lewis Carroll’s poem The Hunting of the Snark. The Spanish name of Cirio, meaning candle, originates from the plant's long tapered look, similar to that of candles at nearby missions.

Cultural Significance An indigenous group of people native to Sonora, the Seri, believe touching the Boojum tree will cause undesirable, strong winds to blow. Furthermore, botanists used to believe mainland patterns of distribution of the plant indicated that the Seri transplanted the boojum further in the interior. However, given the Seri belief about the Boojum, which they call cototaj, this belief has been called into question.

Additional Information Fouqueria Coumnaris differs from its relatives in the ocotillo family by growing in the winter. Boojum trees were previously believed to only grow inches per year and reach up to 700 years old. Scientists now know that the plants can grow up to as much as 1 to 2 feet during a wet year. Additionally, repeated photography helped discover that the plants only typically live roughly a century. Large individual Boojum are particularly susceptible to direct hurricane events which cause significant destruction to the Boojum population every few decades.

Notable Boojum The tallest Boojum on record was in Montevideo Canyon near Bahai de Los Angeles. It was recorded by Robert Humphrey in the 1970s and at the time, was 81 feet tall. Hurricane Nora passed directly over the large boojum in 1997, however, the mighty tree survived. The University of Arizona recently had to remove one of its diseased Boojum trees. The tree was planted in the 1920s or 1930s after a University of Arizona sponsored Baja California trip. The specimen was a noted member of the Krutch Garden and, at 37 feet tall, one of the largest Boojum in the state. Nurserymen plan to attempt to clone the tree using its tips. This process will be documented and is an opportunity for botanists to evaluate opportunities and methods for cloning Boojums. If the precise genotype is successfully saved, it will be reintroduced into Krutch Gardens.

Threats and Conservation Fouqueria Coumnaris trees are pollinated by many different insects. A study of over 20 years yielded a wide variety of species from the same Fouqueria Coumnaris trees in both Baja California and Sonora. However, many of these species of insects have not been seen again for many years. This may be caused by a temporal niche separation. Diverse types of pollinators have been recorded every year prompted by unknown environmental circumstances in which further study is needed. Other known threats to boojum include urban sprawl, expansions of agricultural frontiers, climate change, and harvesting for ornamental wood. The El Vizcaíno Biosphere Region was created in 1988. This protected area is 9,625 sq. miles and is the largest protected wildlife refuge in Mexico. It is home to some boojum, as well as many other protected species. The El Vizcaíno Biosphere Region borders on the Valle de los Cirios. The Valle de los Cirios, located near Guerrero Negro on the Baja California Peninsula, is the second-largest wildlife protection area in Mexico. This area was deemed a nationally-protected area in 1980 and encompasses over 9,500 sq. miles. The Valle de los Cirios contains a large population of boojum and is home to the highly endangered Desert Pronghorn. It is listed as a tentative site to become a World Heritage Site.
