https://www.nps.gov/prsf/index.htm https://en.wikipedia.org/wiki/Presidio_of_San_Francisco The Golden Gate National Recreation Area is a U.S. National Recreation Area protecting 82,027 acres of ecologically and historically significant landscapes surrounding the San Francisco Bay Area. For 218 years, the Presidio served as an army post for three nations. World and local events, from military campaigns to World Fairs and earthquakes, left their mark. Come enjoy the history and the natural beauty of the Presidio. Explore centuries of architecture. Reflect in a national cemetery. Walk along an historic airfield, through forests or to beaches, and admire spectacular vistas. The Presidio lies at the north end of San Francisco at the south end of the Golden Gate Bridge. It can be reached from the north by crossing the Golden Gate Bridge and taking the first exit from Highways 1 and 101; from the east by way of Lombard Street (Highway 101); and from the south via Highway 1 and exiting just before the bridge. William Penn Mott Jr. Presidio Visitor Center The visitor center is the go to place to find out what is happening and what there is to do in the Presidio. Discover the Presidio through a large relief map, inspiring video, engaging exhibitions on history and nature, interactive tools, and knowledgeable staff that can help you uncover the incredible array of experiences possible here.

Of the 99 nurses known to have served in or at Bataan, 22 escaped before the final fall of the Philippine Islands in 1942. The remaining 77, the largest group of women Prisoners of War in American history, were repatriated in 1945. 1945. U.S. Army Nurses climb into trucks as they leave Manila Irvin McDowell Born in Columbus, Ohio, Irvin McDowell (1818–1885) initially attended the College de Troyes in France before graduating from the U.S. Military Academy at West Point in 1838. After completing his education, McDowell served as a tactics instructor at the Academy before joining John E. Wool's staff in the Mexican War. Irvin Mcdowell Major Dana Crissy Crissy Field, located in the Presidio of San Francisco, is named after Major Dana H. Crissy. In the early 1900s, Presidio coast artilleryman Dana H. Crissy was full of ambition and fascinated by the new invention of human flight. Imagine the sensation of being lifted into the air, just above the ground, and magically transported somewhere else. Major Dana Crissy Key Messages from 2019 Plant Pathogen Symposium This June, scientists and land managers from as far as Australia and New Zealand gathered at the Presidio’s Golden Gate Club for “Healthy Plants in a World with Phytophthora: the seventh Sudden Oak Death Science and Management Symposium." Explore key messages from the event to learn about what San Francisco Bay Area Parks and nonprofit partners are doing to manage these potentially destructive fungal pathogens. Participants gather around a table covered in plants. Adolphus Washington Greely A man of eclectic talents and persuasions, Alolphus Washington Greely (1844-1935) was one of the most ambitious figures of his day. Though primarily remembered for his famous North Pole expedition, Greely’s colorful career also included service in the Union army during the Civil War and, later, as commander of the U.S. Army’s Pacific Division. Alolphus Washington Greely Western Pond Turtle Monitoring at Muir Beach Reveals Interesting Growth Trends The month of August was turtle trapping season at Muir Beach. Six captive-raised western pond turtles released in 2017 were recaptured using modified catfish traps. Natural Resources Division staff and interns went out each weekday to check the traps and place new mackerel bait in their pouches. This year’s trapping success increased from 2017, when one turtle evaded trapping for three weeks! Western pond turtle on a log sticking almost vertically out of the water Connecting the Dots: The Anza Trail in Sonora The Juan Bautista de Anza National Historic Trail enters the US at Nogales, Arizona, beginning a 1200-mile stretch of historic trail through the deserts and mountains of Arizona and California. However, the origins of Anza expedition of 1775-76 are in Sonora, Mexico. The people on this historic journey were recruited from the mining towns and farmlands of Sonora and Sinaloa. Anza Trail staff had the opportunity to trace the trail in Mexico with host country partners. Four riders on horseback in front of a white church The Civil War at Golden Gate The National Park Service is commemorating the 150th anniversary of the Civil War (1861 – 1865.) We acknowledge this defining event in our nation’s history and its legacy in continuing to fight for civil rights. Fort Point Military Intelligence School at the Presidio By the late 1930s, as diplomatic relations between the United States and Japan deteriorated, the U.S. Army established the 4th Army Intelligence School at the Presidio. The army converted hanger Building 640, on Crissy Field, into classrooms and a barracks for a language school which trained Nisei – Japanese Americans born to parents who had come to the U.S from Japan – to act as translators in the war against Japan. historic photo of Japanese-American solders studying at tables Post to Park Transition When the Golden Gate National Recreation Area was formed in 1972, the Presidio was designated to be part of the system if the military ever closed the base. This foresight became a reality in 1989, when Congress decided to close the post as part of a military base reduction program. On October 1, 1994, the Presidio officially ended over two hundred-years of military service to three nations and was transferred to the United States National Park Service. Post to Park Poster Spanish American War - "A Splendid Little War" On April 21, 1898, the United States declared war against Spain. It would be the first overseas conflict fought by the U.S. It involved major campaigns in both Cuba and the Philippine Islands. Remember The Maine pin Presidio of San Francisco Architecture The Presidio of San Francisco represents one of the finest collections of military architecture in the country and reflects over 200 years of development under three different nations. Enlisted family housing National Parks Pitch In to Help Save Monarch Butterflies As scientists and citizen scientists have noted, insect populations are plummeting across the globe. Monarch butterfly populations are no exception. Recent counts show that the western population has experienced a precipitous drop. As of 2018, the population of monarchs overwintering along the California coast stands at just 0.6% of what it was in the 1980s. Monarch butterflies among eucalyptus leaves, viewed through a scope Plot Twist in the Presidio Last year, Presidio ecologists installed a webcam above a red-tailed hawk nest to capture the action during the upcoming breeding season. Thousands of viewers tuned in to watch as the resident pair of hawks fixed up their nest, laid eggs, and raised two healthy chicks. This year’s breeding season started off much the same as the last. But then a pair of great horned owls also began visiting the nest. Cue the drama. Red-tailed hawk facing off with a great horned owl, both with their wings outstretched How will Climate Change Affect Bay Area National Park Birds? The National Audubon Society has created research summaries for 274 national park units that describe how projected changes in climate under different emissions scenarios are likely to affect local bird populations. Hummingbird and house finch on the same branch Patriotism and Prejudice: Japanese Americans and World War II One of the most poignant and sadly ironic home front stories of World War II has deep connections to the Presidio. Even as Presidio officers issued orders to relocate Americans of Japanese ancestry to internment camps after the attack on Pearl Harbor in December, 1941, a secret military language school trained Japanese American soldiers only a half mile away.

Estimating Population Size of a Rare Damselfly to Support Reintroduction Efforts Estimating the population size of a rare species is incredibly useful for their management and conservation. One of the rarest Odonates (damselflies/dragonflies) in the U.S., the San Francisco forktail damselfly occurs in only a few sites around the Bay Area, including the Presidio’s Fort Point. Damselfly with an identifying number on its wing Water Quality Monitoring in the Presidio of San Francisco Water quality is an indicator of the condition of aquatic habitat and is also an important indicator of the overall health of watersheds. In partnership with the Presidio Trust, National Park Service Inventory and Monitoring Program staff conduct monthly water quality monitoring at 16 sites in the Presidio to determine long-term trends in water quality parameters. These include water temperature, pH, dissolved oxygen, nitrate (as nitrogen), phosphate, and coliform bacteria.

Trays of young plants in a greenhouse Marin County Vegetation Map & Landscape Database Project Underway, With Plans to Expand A broad coalition of Marin County land management agencies and other partners have joined forces to meet their common need for a fine-scale vegetation map and landscape database. The first phase of this project will create digital aerial photos at a resolution of six inches, and three-dimensional landscape imagery through LiDAR surveys. LiDAR imagery of a segment of a Sonoma County river, highlighting flood risk areas Lizards Get a Helping Hand in the Presidio Western fence lizards are important consumers of invertebrates. They are also a food source for larger predators themselves. However, over a decade of surveys and citizen science observations, they have only been found in the western part of the Presidio. Close-up of a western fence lizard Wintering Monarch Butterflies at the Presidio Monarch butterflies have begun their migration to wintering sites in California, including Rob Hill Campground in the Presidio. Monarch numbers have been low at this site over the last 20 years, but the last two years have shown record numbers. Monarch butterfly perched on a cluster of red berries Transformative Quartermaster Reach Restoration Project to Begin in the Presidio The Presidio Trust, Golden Gate National Parks Conservancy, and Golden Gate National Recreation Area have worked to restore the Tennessee Hollow Watershed for over two decades. However, one key part of the watershed, where the creek connects to Crissy Marsh, remains buried under a sea of pavement and confined to a 72-inch storm drain. Next month, that will start to change. Artists rendering of a restored Quartermaster Reach Marsh John Harris Fights Back Against Discrimination In the late 19th century, a new California civil rights law was put to the test after San Franciscan John Harris was turned away from Sutro Baths because he was black. His experience provided a unique opportunity to see if the recently ratified legislation, meant to ensure equal access in public places, could actually compel change. News Headline The Panama-Pacific International Exhibition The vast fair, which covered over 600 acres and stretched along two and a half miles of water front property, highlighted San Francisco’s grandeur and celebrated a great American achievement: the successful completion of the Panama Canal. Nine years earlier, San Francisco experienced a terrible earthquake, declared one of America’s worst national disasters. The city overcame great challenges to rebuild and by the time the Exposition opened in 1915. View of the South Gardens and the Tower of Jewels, 1915 1906 Earthquake and the Army In the early dawn light of April 18, 1906—at 5:12 a.m.—the ground under San Francisco shook violently for a less than a minute. Though damage from the earthquake was severe, the ensuing fires were truly catastrophic. Thirty broke out almost immediately, burned for three days, and destroyed over five hundred blocks in the heart of the city. Soldiers from the presidio walking in the rubble from the earthquake Rare Bees Return to Restored Presidio Sand Dunes Presidio Trust stewardship staff have discovered a sizeable colony of rare silver digger bees in newly restored Presidio sand dunes. Significant numbers of this species haven’t been spotted in San Francisco since 1928. The sand-loving bees returned to the area after stewardship staff removed invasive ice plant, allowing the original sand dune ecosystem to flourish. Siver digger bee in flight Ancient Redwoods Planted in the Presidio The Presidio Trust and guests from the Archangel Ancient Tree Archive planted 75 redwood saplings in the Presidio of San Francisco on December 14th. The special saplings are coast redwoods, the world's tallest trees. They are also clones from ancient specimens, donated for this effort.

You can now peek in on a mating pair of red-tailed hawks nesting high up in one of the Presidio’s blue gum eucalyptus trees. The pair are regular residents at the site, and have returned to this same nest over the past few years. Red-tailed hawk in its nest, looking up towards the camera Mates for a Rare Manzanita Offer Hope for Its Future The Franciscan manzanita was considered extinct in the wild for seven decades until a single plant was discovered in the Presidio in 2009. The plant was saved and is now protected but it cannot reproduce without "mates". Last year, the Presidio Nursery worked with the UC Berkeley, East Bay Regional Parks, and San Francisco botanical gardens to grow plants from their collection of original Franciscan manzanitas, saved from other areas of San Francisco. A blooming Raven's manzanita planting Streamflow Monitoring in the San Francisco Bay Area The amount of water flowing in a stream, or streamflow, is among the most useful factors available for understanding watershed and stream health. The San Francisco Bay Area Network Inventory and Monitoring Program and its partners monitor streamflow in selected streams at Golden Gate National Recreation Area, Pinnacles National Park, Point Reyes National Seashore, and the Presidio of San Francisco. Brisk winter flows in Redwood Creek Stickleback Help with Mountain Lake Mussel Reintroduction California floater mussels are native freshwater filter feeders that consume algae and improve water quality in the shallow lakes and slow moving streams they inhabit. For the past few years, the Presidio Trust has been partnering with Missouri State University to raise this rare species in captivity for reintroduction into Mountain Lake. This year, biologists started a new approach to complement captive rearing that involves the mussel's larval host fish. Close-up of stickleback fin with small white dots visible Adelbert von Chamisso French-born explorer and naturalist Adelbert von Chamisso (full name: Louis Charles Adélaïde de Chamisso de Boncourt) (1781-1838) visited the San Francisco Bay area in the early nineteenth century. During his time in California, Chamisso studied a number of indigenous plant and animal species and his inventory is considered a valuable ecological record to this day. Adelbert Chamisso Charles Young - Buffalo Soldier Leader among the legendary "Buffalo Soldiers", Charles Young (1864-1922) served in the segregated U-S Army of the 19th and early 20th centuries. Charles Young, Buffalo Soldier Corridos: Stories Told Through Song The corrido is a traditional Mexican song style that has evolved over the past 200 years in northern Mexico and the southwestern United States. Corridos are all about storytelling. They tell of battle victories (and loses), individuals taking on the establishment, the lives of great or notorious people, and – perhaps the most ancient type of story in human history – the epic journey. Learn about this enduring tradition and listen to a corrido about the Anza Expedition of 1776 A woodcut illustration of four people singing and a man playing guitar Presidio Bee Discoveries Inspire Joy and Concern Earlier this spring, ecologists made a happy observation in the restored 2-acre patch of dunes at Rob Hill in the Presidio of San Francisco. For the second year in a row, large numbers of locally rare silver digger bees were busily digging nests and visiting flowers among the dunes. But a recently completed inventory revealed that some other bees in the park may not be doing as well. Close-up of a black-tailed bumble bee visiting a flower. First Pupping Season Underway for New Presidio Coyote Pair Last winter, an unknown female coyote passed through the Presidio of San Francisco. Presidio Ecologist Jonathan Young was able to put a temporary GPS collar on her before she left. Last summer, she returned with a mate and drove out the resident alpha coyote pair. Their battle was captured on a restaurant security camera. Now coyote 15F, the new alpha female, and her mate are probably caring for their first litter of pups in their new Presidio territory.

Pollinators - Hummingbirds Hummingbirds (family Trochilidae) are amazingly adapted pollinators, and they play an important role in pollination. A flying hummingbird hovers next to a red flower Concepcion Arguello & Nikolai Rezanov: A Presidio Love Story In the late eighteenth century, a young Spanish girl and a Russian explorer fell in love at the Presidio. Though challenged by different languages and cultures, the romance of Maria de la Concepcion Marcela Arguello and Nikolai Petrovich Rezanov spawned a legend that continues to capture the hearts of people today. Painting of Maria de la Concepcion Marcela Arguello & Nikolai Petrovich Rezanov Army Nurse Corps Congress established the Army Nurse Corps in 1901. Nurses were the first women in the Army and U.S. Army General Hospital at the Presidio was the first Army hospital to employ them. By 1902, 41 nurses were part of the hospital staff.

Places of World War II in the San Francisco Bay Area World War II dominated the social, economic and political landscapes of the mid-20th century, setting in motion momentous events that still shape the world we live in today. The communities that ring the San Francisco Bay were irrevocably altered by that wartime era and still bear its visible marks in the remains of military bases and coastal defense fortifications, ships and shipbuilding facilities, worker housing and day-care facilities. This travel itinerary highlights 31 Chinatown, San Francisco Not Your Ordinary Culverts: Bringing Native Oysters Back to the Presidio This year the Presidio is expanding the wetlands along its northern waterfront at a site known as Quartermaster Reach. The project will allow water to flow through new culverts, or underground water tunnels, beneath Mason Street. This will create seven acres of new habitat for birds, plants, and other native species. But the culverts for this project will not be your usual culverts. They’ll also help create habitat for native Olympia oysters. Close-up of tiny Olympia oysters. New Marshland and Trail Open in the Presidio on December 11, 2020 On November 13, the Presidio Trust removed an earthen berm and some sheet pilings that were preventing water from flowing through new culverts (and oyster habitat!) beneath Mason Street. As the tide rose, salt water from the Bay and Crissy Marsh flooded through for the first time to meet the fresh water of the Tennessee Hollow Watershed. Now, visitors can get their first up-close look. Socially distanced people in safety gear, planting wetland plants in a barren, muddy landscape. Scientist Profile: Alex Iwaki, Hydrology Monitor "While I was in college, I didn't want to go back home for the summer to work at the local grocery. I applied for a bunch of environmental internships and got a fisheries internship in Colorado. I had no prior experience or any interest in fish, but I thought 'why not?' I went out there, learned a lot, and had an amazing time. After the fisheries internship, I knew I wanted to continue to work in natural sciences." Alex Iwaki San Francisco: Where the Plates Meet The San Francisco Bay Area sports “coasts with abundant marine and terrestrial resources, a sheltered deep-water harbor, hills and mountains with plentiful forests, and streams and rivers providing water and transportation routes, including to the goldfields of the Sierra Nevada Mountains.” As a result, it has attracted people to it for millennia. But why does the area feature such enchanting diversity in the first place? Coastal rock formation featuring four differently colored and textured types of rocks. New Perspectives On Old Teachings "In a few hours, I will be surrounded by our community of volunteers, who have come to celebrate ‘Eid’ in the parks, a festival that marks the end of Ramadan and is celebrated by Muslims across the world. On this special day, my reflection takes me back to when I first learned about the five pillars of Islam. While in my childhood, these duties were confined to the mosque and my community, in my adulthood, I started to see these pillars show up in my connection with nature." Two women holding an enormous, overflowing bag of freshly pulled weeds. California Ringlets Get Helping Hand Returning to Presidio Grasslands The California ringlet was last seen in San Francisco’s Presidio in 2007. Grassland habitat loss and degradation from before the Presidio became a park contributed to its extirpation. Now, after more than two decades of grassland restoration, the time is ripe for this lost butterfly to return. But the California ringlets can't return on their own. They are about the size of a quarter, and they're weak flyers. So this spring, the butterflies have been getting a helping hand. Small butterfly the color of dried grass.

They’ve had some good news—the first population estimate in five years revealed stable numbers despite the drought—but also been confronted with diminishing water levels threatening the species' remaining stronghold near Fort Point like never before. Iridescent black, green, and blue insect with a long, slender abdomen and long, folded wings. Can San Francisco Parks Support the Reintroduction of California Quail? It’s ironic: the official bird of San Francisco and the State of California, the native California quail, is locally extinct within the city of San Francisco. Land managers have mused about reintroducing the iconic species. But what would it take? Adult quail mid-stride. © er-birds / Photo 101950384 / 2021-11 / iNaturalist.org / CC BY-4.0 Biologists Seek to Reintroduce More Genetically Robust Stickleback Population at Presidio’s Mountain Lake Should a reintroduced wildlife population come from one source population, or from several? This question is actively debated among conservation biologists. Presidio Trust biologists tried the former approach in 2015 when they first reintroduced threespine stickleback into Mountain Lake from a population in nearby Lobos Creek. Now, after what may have been a disease-related die-off in 2020, they will draw on three local stickleback populations for a second reintroduction. Small olive fish with spines on its back. The Presidio Raptor Cam Returns: Nesting Red-tailed Hawks Hatch Two Chicks! In 2018, the Presidio of San Francisco’s live “Hawk Cam” was established above a nest located 100 feet up in one of the blue gum eucalyptus trees near the Main Post. Over a few seasons, it’s given all of us an up-close and personal look at nesting raptors in the park – and it’s back. The same breeding resident pair of hawks have returned to their nest four years later – and two chicks hatched starting on Easter weekend! Overhead view of red-tailed hawk parent with two fluffy white chicks half-under its breast. San Mateo Fine Scale Vegetation Map Complete Fine scale vegetation maps are precise snapshots of plant communities (and other land cover types) across a landscape at a given time. They're also invaluable tools for land stewards. A coalition of agencies and partners just completed such a map of San Mateo County, plus federal lands in San Francisco. It shows 106 land cover types with 97,582(!) polygons and depicts the landscape as it was in 2018, when the project team acquired the map's foundational aerial imagery. Screenshot of a web map interface. The map is titled 'San Mateo Fine Scale Vegetation Web Map'. The Men of Baker Street In 1918, the United States Army learned that the Presidio of San Francisco was home to men who desired other men. The Men of Baker Street were incarcerated on Alcatraz Island for five months awaiting their courts-martial. These courts-martial found all six soldiers guilty and dishonorably discharged. They forfeited all pay, and five were sentenced to be “confined at hard labor” for sentences ranging from 2-10 years. Botany News – July 2022 This July, the Invasive Species Early Detection team mapped invasive plants at John Muir National Historic Site and at Rancho Corral de Tierra and the Presidio of San Francisco in Golden Gate National Recreation Area. Yellow star thistle, Algerian sea lavendar, and Oppositeleaf Russian thistle emerged as noteworthy early detections. Meanwhile, the Plant Community Monitoring team surveyed freshwater marsh plots and shine a spotlight on the ecological benefits of poison oak.
