Monumental Questions - Federal Public Lands

Kristie Ehrhardt • November 5, 2025

If you’re a friend of Tuleyome you likely know a bit about our (it belongs to all of us) newly expanded favorite National Monument - the Berryessa Snow Mountain National Monument. You may also recognize that federal public lands are lands that are owned and/or managed by the United States federal government for the enjoyment of its citizens. And, you probably know that in addition to national monuments there are also national parks, national forests and national historic places but did you know that there are many more public land designations as well?!


There are many (MANY!) different types of federal public lands. Most of them are held for conservation, resource management and public recreation. The United States Department of the Interior (DOI) oversees several federal agencies that manage various public land designations and the United States Department of Agriculture (USDA) oversees other agencies that steward public lands. Federal public lands in the United States, District of Columbia and US territories total approximately 640 million acres and occupy nearly 30% of the land area. 


The National Park Service is an agency within the DOI and oversees not only national parks but also most national monuments and other natural, historical and recreational properties with various title designations or units.  These include national preserves, national lakeshores and seashores, national rivers and wild and scenic rivers and national scenic and historic trails, among others. Today The National Park Service currently manages 433 combined parks/units including 63 national parks, 87 national monuments, 75 national historic sites, 64 national historic sites and many other designations totaling 85 million acres in all 50 states, the District of Columbia and US territories. Their management focus is preserving the ecological and historical integrity of these special places for public use and enjoyment. 


The Bureau of Land Management (BLM) is a federal agency also under the direction of the DOI.  The BLM’s mission is “to sustain the health, diversity and productivity of public lands for the use and enjoyment of present and future generations.” We here at Tuleyome think that’s pretty dang good and we often partner with them on varying components of public land use and enjoyment. The BLM is responsible for the management of a substantial portion of the nation’s public lands including some of our most historic and scenic landscapes and natural resources for all to enjoy.


The United States Fish and Wildlife Service (USFWS) is another agency operated under the DOI and is the oldest conservation agency in the United States. It was established in 1871 to help monitor the country’s game fish populations. Today the USFWS manages our nation’s wildlife refuges to conserve the habitat, plants and wildlife found there. The national wildlife refuge system began with Pelican Island in 1903 and today there are over 560 refuges across the country. It’s been said that if “national parks are America’s best idea, national wildlife refuges are America’s best-kept secret”. Although, they don’t seem like a very stealthy secret since they receive over 50 million visitors a year!


The United States Forest Service (USFS) was established in 1905 and is an agency under the USDA. It is the United States’ predominant forestry agency leading the world in sustainable forest and grassland use, management and stewardship, research and conservation. Today they are responsible for the management of 154 national forests and surrounding areas that total nearly 200 million acres in 43 states, the Virgin Islands and Puerto Rico. The agency also provides stewardship assistance to tribal, state and local governments, private landowners and corporations to improve conditions on about 900 million acres of forests in the U.S. 


Fun fact - Yellowstone was the United States’ first national park established in 1872. But, at the time Wyoming was still a U.S. territory so Yellowstone was managed by the federal government using the Army and the African American Buffalo Soldiers. 

 

Fun fact - the designation National Monument has been given to many different sites ranging from natural reserves, historic military scenes, prehistoric ruins, fossil sites AND to the Statue of Liberty. 

Fun fact - there is at least one national wildlife refuge in every US state and territory.


Fun fact - The Forest Service obviously manages forests but did you know that they also manage grasslands?


Did you know… that the Berryessa Snow Mountain National Monument is jointly managed by both the BLM and the USFS, not the National Park Service!?


Whether you’re exploring places where you won’t find a motorized vehicle or places where you might not find a parking spot, you can bet there is at least one type of federal public land just a hop, skip and a jump from you!


The numerous designations within the National Park System sometimes confuse visitors. The names are created in the Congressional legislation authorizing the sites or by the president, who proclaims "national monuments" under the Antiquities Act of 1906. Many names are descriptive—lakeshores, seashores, battlefields—but others cannot be neatly categorized because of the diversity of resources within them. In 1970, Congress elaborated on the 1916 National Park Service Organic Act, saying all units of the system have equal legal standing in a national system.


National Park

These are generally large natural places having a wide variety of attributes, at times including significant historic assets. Hunting, mining and consumptive activities are not authorized.


National Monument

The Antiquities Act of 1906 authorized the President to declare by public proclamation landmarks, structures, and other objects of historic or scientific interest situated on lands owned or controlled by the government to be national monuments.


National Preserve

National preserves are areas having characteristics associated with national parks, but in which Congress has permitted continued public hunting, trapping, oil/gas exploration and extraction. Many existing national preserves, without sport hunting, would qualify for national park designation.


National Historic Site

Usually, a national historic site contains a single historical feature that was directly associated with its subject. Derived from the Historic Sites Act of 1935, a number of historic sites were established by secretaries of the Interior, but most have been authorized by acts of Congress.


National Historical Park

This designation generally applies to historic parks that extend beyond single properties or buildings.


National Memorial

A national memorial is commemorative of a historic person or episode; it need not occupy a site historically connected with its subject.


National Battlefield

This general title includes national battlefield, national battlefield park, national battlefield site, and national military park. In 1958, an NPS committee recommended national battlefield as the single title for all such park lands.


National Cemetery

There are presently 14 national cemeteries in the National Park System, all of which are administered in conjunction with an associated unit and are not accounted for separately.


National Recreation Area

Twelve NRAs in the system are centered on large reservoirs and emphasize water-based recreation. Five other NRAs are located near major population centers. Such urban parks combine scarce open spaces with the preservation of significant historic resources and important natural areas in location that can provide outdoor recreation for large numbers of people.


National Seashore

Ten national seashores have been established on the Atlantic, Gulf and Pacific coasts; some are developed and some relatively primitive. Hunting is allowed at many of these sites.


National Lakeshore

National lakeshores, all on the Great Lakes, closely parallel the seashores in character and use.


National River

There are several variations to this category: national river and recreation area, national scenic river, wild river, etc. The first was authorized in 1964 and others were established following passage of the Wild and Scenic Rivers Act of 1968.


National Parkway

The title parkway refers to a roadway and the parkland paralleling the roadway. All were intended for scenic motoring along a protected corridor and often connect cultural sites.


National Trail

National scenic trails and national historic trails are the titles given to these linear parklands (over 3,600 miles) authorized under the National Trails System Act of 1968.


Affiliated Areas

In an Act of August 18, 1970, the National Park System was defined in law as, "any area of land and water now or hereafter administered by the Secretary of the Interior through the National Park Service for park, monument, historic, parkway, recreational or other purposes." The Affiliated Areas comprise a variety of locations in the United States and Canada that preserve significant properties outside the National Park System. Some of these have been recognized by Acts of Congress, others have been designated national historic sites by the Secretary of the Interior under authority of the Historic Sites Act of 1935. All draw on technical or financial aid from the National Park Service.


Other Designations

Some units of the National Park System bear unique titles or combinations of titles, like the White House and Prince William Forest Park.


Types of federal public lands

  • National Parks: Managed by the National Park Service (NPS), these lands are preserved for their natural and cultural resources for future generations to enjoy. 
  • National Forests and Grasslands: Managed by the U.S. Forest Service (USFS), these areas are used for multiple purposes, including timber, recreation, and wildlife management. 
  • National Wildlife Refuges: Managed by the U.S. Fish and Wildlife Service (USFWS), these lands are primarily for the conservation of fish, wildlife, and plants, but many also allow compatible wildlife-dependent recreation like hunting and fishing. 
  • National Conservation Lands: These are public lands designated for their conservation value and are managed by the Bureau of Land Management (BLM). The BLM manages more public land acreage than any other agency. 

Management and use

  • Management: Federal lands are managed by various agencies, with the U.S. Forest Service (Department of Agriculture) and the Bureau of Land Management, the National Park Service, and the U.S. Fish and Wildlife Service (all under the Department of the Interior) being the primary ones. 
  • Resource Extraction: Some federal lands are available for resource extraction like oil, gas, and mining, which can be a source of controversy and debate over conservation versus extraction. 
  • Recreation: The lands offer a wide range of recreational opportunities, such as hiking, camping, wildlife viewing, hunting, and fishing. 
  • Information: You can find information about specific public lands, including maps and regulations, on the official websites of the managing agencies.

Have you ever been hiking in the Berryessa Snow Mountain National Monument (or almost anywhere else in the world for that matter) and come across a plant or animal and not been able to identify it? Have you ever thought, “hmmm, if only there was an easily accessible phone app that could help me identify this thing nearly instantly?” If that exact thought wandered through your cranium; boy, oh boy are you in luck! Enter iNaturalist! The iNaturalist app is primarily an online social community sharing their findings and information to network and help others learn about the environment. The iNaturalist website states that “INaturalist is crowdsourced species identification system and an organism occurrence recording tool. You can use it to record your own observations, get help with identifications, collaborate with others to collect this kind of information for a common purpose, or access the observational data collected by other iNaturalist users.” iNaturaist was developed as a Master’s final project by Ken-ichi Ueda, Nate Agrin and Jessica Kline at UC Berkeley’s School of Information back in 2005; the same year that YouTube and Reddit were initially introduced to the public - a vintage year for social media developments! It officially launched in 2008 and work continued on the site and iNaturalist, LLC was born in 2011. By 2017 National Geographic was onboard and in 2023, what began as a student project became an independent nonprofit organization that grew into a globally recognized Citizen Science driven platform that connects millions of people to the biodiversity around them. iNaturalist is a compilation database that contributes valuable collective intelligence to conservation and science from around the world. iNaturalist is a valuable tool for species identification as well as organism occurrence crowdsourced information, it is also a practical resource for species identification and distribution. And guess what else! It’s free to use. Sound good? Want to know how you can benefit from iNaturalist? You can use iNaturalist to record your own species observations and locations. You can use it to help identify species you aren’t sure about or may be new to by using other individuals' entries. You can even work with other users to collaborate and continue to add information to the site or you can access other’s information regarding species observations and occurrences. You can look up and enter data using scientific nomenclature or common names. You can look at other’s photos and locations for reference and contribute your observations. Students and Professors alike are using and recommending iNaturalist. So how’s it been going? On March 20, 2008, the very first entry was made into iNaturalist. To save you from doing the math I’ll tell you that iNaturalist just had its 18th birthday! Guess how many observations people have recorded in those 18 years… you’ll never guess so I’ll just tell you - iNaturalist has over 3.5 million individual observations ! And it’s increasing every moment, you can literally watch the counter on their homepage rise. Guess how many individual species have been recorded! Not to be disparaging but you’ll never get it...iNaturalist is up to just under 560,000 species ! There are currently over four million registered individuals making and recording observations and more than 483,000 people helping other people by making identifications. In just 18 years, a student project has grown into a globally recognized and respected tool to make and record species observations adding information to a world-wide biodiversity database. If you want to be a part of this community simply download the iNaturalist app or go to their website and get out there and start entering your observations. The Berryessa Snow Mountain National Monument region is an incredible place to practice using iNaturalist because it hosts such a huge diversity of habitats and species.

I’m sure a lot of us already know the danger that foxtails pose to our dog and cat friends and hopefully nobody reading this minds, but I’d like to try extra hard to make sure that everyone reading this knows about the menacing nature of foxtail barley. Foxtail barley ( Hordeum sp.) is a member of the grass (Poaceae) family and is native (I just learned this!) to North America. Although it is a native species, it is considered “weedy” because it readily establishes and can outcompete other species because it thrives in both moist and drought prone environments. It is also known by other cute little woodland creature names such as squirreltail barley, bobtail barley and skunktail barley but lemme tell you, it’s not as endearing as the common names suggest. The name “foxtail” is a general term for grasses in the Hordeum (barley genus). Foxtail barley (foxtail) is a perennial bunch grass that thrives in previously disturbed areas and is somewhat unique in that it is tolerant of saline and/or alkaline soils where the majority of other upland species cannot survive. Foxtails can germinate in the spring or the fall and those that germinate in the fall resume growing early the following spring often outcompeting other spring germinating plant species. Because it is salt tolerant it can be found on coastal beaches and along the edges of brackish and salt marshes as well as road sides, yards and fields. Foxtail usually doesn't exceed one three feet tall when left undisturbed but if the plants are mowed, they can flower and produce seed much closer to the ground as well. Seed heads are pale green and appear as a square-shaped (characteristic of barley) bushy spike. The stems are erect with soft blue-ish gray-green rolled leaves and seed heads have long awns. Since plants can’t get up and wander about, they need a method to disperse their seeds. That method for foxtails is mainly by hitchhiking on other things that move from one location to another. Up close, individual seeds look like a fox’s bushy tail and their shape helps them to attach to your pets and you. And because the seeds are barbed, they can get embedded in our furry friend’s ears, eyes and skin and often requires a vet’s steady hand (and your pocketbook) to remove them. They can be especially dangerous and sometimes fatal if they get into your pets nose or blood stream. Right now, at least for a few more days, the foxtails are still green and soft. But, as the temperatures rise and the vegetation begins to dry out, the hazards posed by foxtails begin to rise with the mercury. As the seed heads mature they become golden in color and very fragile. This is when they are the most dangerous to our pets as they are easily broken apart from the plant. Eventually the seeds get harder and drop to the ground where if stepped on they can embed themselves into your bare feet or your pet’s paws. Although it seems nearly impossible to avoid foxtails there are some ways to help you and your furry buddy continue to enjoy hiking through the Berryessa Snow Mountain National monument or a leisurely stroll through your neighborhood. Avoid areas where you’ve seen foxtails before and pay attention to where your friend wanders - especially during the summer months when the foxtails are dry and brittle Keep your dog’s fur trimmed and short so there’s less surface for the seeds to attach to Do a quick nose to tail check for foxtails after each walk or hike being sure to check between their foot pads A basket muzzle may help keep their nose and mouth clear of foxtails while still allowing your pup to pant If your furry friend is coughing, gagging, sneezing, snorting or pawing at their face or ears or limping, there may be an embedded foxtail that you aren’t able to see. It’s best to have them checked out by a vet to make sure they are all clear. If they have picked up a foxtail, removing it as soon as possible is usually less invasive for your companion and your wallet. Just by spending a little extra time and effort, you and your pets can still Enjoy Outside even during foxtail season!

Finally, they’re back!! I’ve been waiting and watching for them and just this week I heard the first one of the summer. Swainson’s hawks ( Buteo swainsoni ) make an impressive journey every fall and then do it again in reverse every spring. Where do they go and why is it so impressive you ask? Stay tuned and find out! Our Swainson’s hawks, the hawks that summer here in California’s Central Valley, that raise their babies in old cottonwoods and valley oaks along our riparian areas, the same hawks that weigh less than two pounds and gorge themselves on grasshoppers and rodents all summer long, travel all the way to ARGENTINA! That is nearly 6,500 air miles and would take 18-20 hours on a commercial flight without any layovers. Are you impressed? If not, consider the fact that they do that epic journey TWICE a year! Swainson’s hawks are a close relative of our year-round resident, the Red-tailed hawk and are similar in size and habitat requirements. Swainson’s hawks have two color morphs; a light morph and a dark morph, and although both sexes wear the same colors and patterns, females are typically slightly larger and heavier than males. In the light color morph both females and males sport a chocolate-colored “bib” with a white throat and face patch and bright yellow rostrum. Their tails are barred and their flight feathers are dark with a light-colored leading edge - a unique color pattern in North American raptors. Dark morphs are all dark chocolate brown with the same barred tail with a light patch just under it. Swainson’s hawks occur roughly west of the Missouri River during the warm summer season and like some people I know, take off for warmer regions when the summer weather turns chilly. In California, Swainson’s hawks nest primarily in the Central Valley although there are small populations in northeastern California, Shasta Valley, Owens Valley and the Mojave Desert. Historically it was estimated that California supported over 17,000 breeding pairs but in 1980 that number had declined to only 375 breeding pairs. In 1988 it was up to an estimated 550 breeding pairs statewide and in 2005 the number of breeding pairs had inched up to just under 2100. They were listed as a threatened species in California in 1983 due primarily to habitat loss.  An endorsement of their adaptability, Swainson’s hawks have not only learned to co-exist with many agricultural practices but they in fact thrive alongside irrigated pastures and tractors which has helped their number improve. Swainson’s hawks have learned that the rumble of a tractor pulling a harrow disk equates to what we might consider a drive through meal. They’ve also learned that when a rancher turns on the water and begins to flood irrigate a pasture, that advancing waterline flushes out underground rodents resulting in a heavenly smorgasbord of unwelcome pests to the human behind the water controls. I’ve seen 20 hawks lined up following the waterline with 20 more circling waiting their turn at the chow line. If their migratory journey hasn’t impressed you, their rodent/lizard/grasshopper eating capacity surely will. These gourmands will gorge themselves so heavily that they realistically cannot lift themselves off the ground for a time which results in oodles of hawks hopping about like unathletic feathered toads. Mutualism at its finest - the hawks get a gourmet meal and farmers and ranchers get free pest control. If their stamina and gluttony doesn’t impress you, maybe this will. It’s not uncommon for wild Swainson’s hawks to live and continue breeding into their 20’s. But that’s not just hanging around and raising babies in the laid back summer months. During those 20 years, that individual bird has flown about 260,000 miles to safely return to the same area, perhaps the same tree, that held the nest that it fledged from. That’s undeniably impressive!
