Monumental Questions - What makes Woodland Regional Park Preserve a Gateway to Berryessa Snow Mountain National Monument?

Nate Lillge • March 22, 2023

Woodland Regional Park Preserve (WRPP) is a local sample of what is available to enjoy in the Berryessa Snow Mountain National Monument. Within the 330,780-acre monument boundary, elevations reach 7,000 feet with many different ecosystems to explore. These habitat types support an enormous variety of plant and wildlife species including many that are listed as threatened or endangered. 


When visiting the Berryessa Snow Mountain National Monument, one can explore seven different ecosystems: chaparral, oak grassland, riparian, mixed evergreen forest, coniferous forest, closed-cone forest, and sub-alpine. Each of these ecosystems has wonders to discover.


Chaparral ecosystems are dominated by short, evergreen shrubs with hard, waxy leaves. The branches of these bushes become intertwined as they grow which makes travel difficult off-trail. Oak grasslands are much easier to travel cross country as the oak trees grow some distance apart with little understory. Riparian ecosystems are those found immediately adjacent to water. Cache Creek and Putah Creek, along with other smaller streams, provide refuge for plants and animals during the hot, dry summer.


Mixed evergreen forests are dense stands of evergreen trees/bushes that are adapted to hot, dry conditions. Coniferous forests are dominated by coniferous trees with an understory and canopy. Closed-cone forests are defined as stands of trees that have hard, pitch-covered cones that require heat or fire to open.


Woodland Regional Park is gateway to Berryessa Snow Mountain – it offers some of what makes the monument special. Visitors to the park can experience riparian and grassland ecosystems, similar to those in the northern Inner Coast Range mountains with many of the same species. Birding, botany, hydrology can take place on site. An ADA trail provides the opportunity for guest to enjoy nature while proposed future trails on site will take hikers to more remote areas of the preserve to experience a wilderness hike. The mountains of Berryessa Snow Mountain National Monument are the high point of the watershed while WRPP - and the area around Woodland - is the low point. The geology of the monument creates the amazing soils and habitats at WRPP. Vernal pools and alkaline soils are present because of the sediment that has been carried out of the mountains by Cache Creek.


Guests at last Saturday’s Spring Thing got the opportunity to experience this gateway first hand. Tuleyome staff, Board members, and our amazing volunteers helped guests understand how WRPP and Berryessa Snow Mountain National Monument are connected.

Last year tested us. We watched as the administration attempted to auction off millions of acres of public lands, an unprecedented attack on places we’ve fought to protect for decades. We saw rollbacks of critical environmental protections and threats to lands that belong to all of us. But we also showed up. Together, as a community, we rallied, we organized, and we pushed back against some of the most aggressive land sell-offs ever proposed. And we won some of those fights. In December, just before Congress recessed, Senator Padilla introduced the Protecting Unique and Beautiful Landscapes by Investing in California (PUBLIC) Lands Act , a beacon of what’s possible when we refuse to give up. This isn’t just another bill. It’s a statement that California is refusing to let our public lands become bargaining chips. The PUBLIC Lands Act would protect over 1.7 million acres of California public lands throughout northwest California, the Central Coast and Los Angeles County. That protection includes 550,000 acres of new wilderness and nearly 700 miles of wild and scenic rivers. It includes provisions for forest restoration and fire resilience on another 871,000 acres, work that is desperately needed. This package pulls together three essential bills: Congressman Huffman's Northwest California Wilderness, Recreation and Working Forest Act , which protects 484,733 acres and 479.8 miles of rivers, old-growth forest, salmon streams and wild places that define the North Coast. Representative Carbajal’s Central Coast Heritage Protection Act secures 385,842 acres including critical habitat in Los Padres National Forest, home to California Condors and threatened watersheds. Representative Judy Chu’s San Gabriel Mountains Foothills and Rivers Protection Act that protects 35,335 acres, expanding access to nature for millions of Angelenos who live in communities with some of the lowest park access in the country despite having mountains right in their backyard. The PUBLIC Lands Act matters because it’s happening now when our public lands face their greatest threats. Our champions in Congress aren’t waiting for a better political moment, they’re fighting for these places when the fight matters most. We will be tracking this bill closely and keeping you updated as it moves through Congress. In the meantime, call your representatives and thank Senator Padilla , Representative Huffman , Representative Carabajal and Representative Chu for introducing this legislation. Let them know you support it. Our voices help move good legislation through Congress, especially when the opposition is loud. If 2025 taught us anything, it's that defending our public lands isn’t a one-time battle. It’s the work we do together, every single day. Bryan Pride Tuleyome Policy Director

It’s true! Tuleyome’s Adventures and Engagement Director Nate Lillge has assembled an incredible guide to the trails located throughout the southern portion of our newly expanded favorite monument. As you may know, the monument is jointly managed by both the Bureau of Land Management (under the United States Department of Interior) and the United States Forest Service (under the United States Department of Agriculture). The two agencies collectively manage and maintain 344,476 acres of natural wildlands in the Inner Coastal Range available for the public to appreciate and explore. That’s where Tuleyome comes in, we want to help you traverse and investigate those acres. Tuleyome’s trail guide not only provides a map of the southern portion of the monument with the trailhead names and locations, but it also shows names of the various trails that can be accessed by those trailheads along with the difficulty rating. It also contains a QR code that will take you to detailed information for each trail, including driving directions, trail maps and hike descriptions. If you’d rather go with a group, Tuleyome can help there too. Check out the Upcoming Events tab on our website to register for one or more of our organized hikes. So, if your New Year’s Resolution was to get out on more hikes in 2026, Tuleyome’s got you covered! Check out the Trail Guide here or look for our booth at one of the many community events that we participate in and pick up a printed copy. And don’t forget about our Youth Boot Bank program if your little hiker needs to borrow some boots; just come see Tuleyome’s Education Associate, Geoff Benn, during Boot Bank office hours, which are also listed under the events tab, and we’ll get your little ones outfitted for the trails too.

Stretching from the Bering Straight off the coast of Alaska south to majestic Patagonia, the Pacific Flyway is one of the paramount migratory pathways in the entire world. Hundreds of species ranging from tiny hummingbirds, songbirds like sparrows and warblers, shorebirds like avocets, sandpipers and whimbrels, waterfowl including many species of ducks and geese to great Bald Eagles combine to equal the billions of birds that use the Pacific Flyway each migration season. With California's mild winters, available wetlands and flooded rice fields, and oodles of food, it’s not hard to see why waterfowl species like the striking white and black Snow Goose spend their winters here. As many as a million and a half Snow Geese will be using the Pacific Flyway and tens of thousands of them will remain here, in our region, for the winter. The City of Chico and surrounding communities come together to celebrate “this magnificent spectacle of nature with the Snow Goose Festival of the Pacific Flyway.” By connecting and showcasing artists, authors, educators, guides and volunteers the festival aims to excite and unite the community by increasing appreciation, awareness, conservation and understanding of the resident and visiting wildlife and their habitats in the Northern Sacramento Valley. The three day festival features art and an auction, a banquet, field trips, family activities and exhibits and workshops! Snow Geese (Anser caerulescens) breed in Greenland, Canada, Alaska and the northeastern tip of Siberia and winter in the warmer regions of southwestern British Columbia, south through the United States and Mexico. There are two color morphs, white which are called “snows” (shocking, I know) and the dark morphs which are called “blues”. Snows are all white with black wingtips while blues have dark bluish-gray plumage and a white head, neck and tip of the tail. Both color morphs have orangy-red legs and feet and a pink bill with black edges that makes it look like they are grinning. Sometimes minerals in the soil or water where they’re feeding can stain their white heads making them look orange. Snow Geese are vocal. Very vocal. Some may say they are extremely vocal and they can often be heard from more than a mile away. Frequently Snow Geese and Greater White-fronted Geese travel together as they are very similar in size and needs. Combined flocks of them can often be heard on winter days and nights as they fly high overhead to their feeding grounds. If you’re looking for a fun way to Enjoy Outdoors and learn more about the Pacific Flyway, Snow Geese and their fellow travelers, venture on up to Chico during the weekend of January 22-25, 2026. They’d love to see you at one of the many events! Please visit the website ( https://snowgoosefestival.org/ ) for a list of activities, to register and for more information. Snow Goose Fun Facts! When Snow Geese are resting or feeding, lookouts keep an eye to the sky watching for threats such as Bald Eagles or other predators which prey on old or injured geese. The lookout will vocalize and the entire flock may spontaneously take flight which is pretty stunning to watch. Snow Goose eggshells stain easily which makes aging the eggs easy, the older eggs will appear dirtier while the more recently laid eggs remain creamy white. Snow Geese populations dropped so low in the early 1900’s that hunting was no longer allowed in the eastern states. From the 1970’s and on, the population has boomed so much that some of their tundra nesting grounds are being impacted by their numbers. Once females arrive at their breeding grounds they may spend up to 20 hours a day foraging but consume nearly nothing once they begin incubating eggs. Snow Goose digestion is remarkably quick, requiring only about an hour or two to go from gullet to ground. Snow Geese make epic journeys by wing but they are not lazy on foot either. Within the first month after hatching, goslings may walk about 50 miles with their parents. When waterfowl molt they lose their ability to fly but a molting Snow Goose can outrun many predators. The oldest known Snow Goose was over 30 years old! Word Play. A group of geese on the ground or water is called a gaggle . That same collection of geese but now in the air are called a skein , a wedge or a team . Hunters use the term “ grind ” for an assemblage of geese while culinary artists use the same term to mean goose meat . BUT, if you simply call them a flock of geese, everyone will know what you’re talkin' about! -Kristie Ehrhardt ( kehrhardt@tuleyome.org ) Tuleyome Land Conservation Program Manager
