Tuleyome Adventures Education Program

It’s easy to turn on the faucet at home and not think much about how the water made its way there. It’s easy, also, to see snow on distant mountain tops, a river flowing through a canyon, a small local pond, and ocean waves crashing on the beach but not to see the connection between each of them. Water is vital to life, needed by all living things, so water education is important. Helping students see these connections and appreciate water’s journey is the primary goal of the Water Trail as part of our Tuleyome Adventures Education Program.

This particular trail is designed for 4th and 5th grade students who focus a lot on the interactions between the hydrosphere, geosphere, and atmosphere during their science course work. Students begin with an activity and demonstration that helps students visualize the amount of water available on Earth and the much smaller amount of water available for human and wildlife use.

From there, students get to take a journey through the water cycle from the perspective of a water molecule travelling around the Cache Creek Watershed area. Students roll special dice and run from one station to the other, making their way between clouds, the ocean, groundwater, Cache Creek, and even plants and animals. As they travel from station to station, they track their movement in their field notebook, collecting data that simulates that of actual water molecules. Students begin to notice that water molecules get “stuck” in certain areas, like the ocean, and move out of other areas rapidly.

Now that students have journeyed through the water cycle, it’s time for them to take notice of their own watershed, the watershed responsible for sending water to our area. Students walk along the trail until they reach a good vantage point of the mountains to the West, the mountains that form the barriers of the Cache Creek watershed. Students take some time to sketch out the watershed in their notebooks. Later, they will add details showing how a single water molecule might move through this watershed.

An important aspect to understand about watersheds is the effect we have on one another through our actions. As students wind up their time on this trail, they will engage in an activity that helps them better grasp this concept. In this activity, students are told they have just received a plot of land and a million dollars. They can do whatever they want on their land, build whatever they want. With paper, crayons, and colored pencils, students go to work creating their dream space.

Once the pictures are drawn, students are seated on either side of a long blue ribbon representing a river that runs through the canyon of a watershed – Cache Creek. Students at the start of the ribbon live at the top of the watershed, in the mountains. Students at the end of the ribbon live at the bottom of the watershed. One by one, students share their drawings and talk about something that might affect their neighbors. Is there runoff that could end up in the river? Did someone need too much water, leaving too little for everyone else? Is something seeping into the groundwater or is there not enough water for wildlife? Through this activity, students start to recognize that each landowner doesn’t work in isolation. As a community, we must work together to protect the journey water takes as it makes its way to our faucets.

Policy Corner: Rolling Back The Antiquities Act, At What Cost?

By Bryan Pride • February 6, 2025

With a new Administration keen on identifying untapped sources for energy and natural resources, discussions on “rolling back” the Antiquities Act of 1906 are rising within Congress and the Administration. The Antiquities Act is one of the most important tools available for the preservation of public lands, water, and historic sites. Passed by a Republican-led Congress and signed into law by President Theodore Roosevelt, the Act has been utilized by eighteen U.S. Presidents— nine Democrats and nine Republicans—who have collectively declared 145 national monuments . This bipartisan legislation remains essential for maintaining the integrity of natural and cultural resources. Under The Antiquities Act, the President has the authority to reserve or withdraw federal lands or waters containing objects of historic, scenic, scientific and cultural significance. This protection prevents potential harm from commercial development, looting, and habitat destruction. Key provisions of the Antiquities Act established several crucial tools for managing resources on public lands. These tools include: Presidential authority to establish national monuments from existing federal lands Requirements to secure permission from federal land managers before conducting archaeological investigations or removing objects Authority for the Secretaries of Agriculture, Interior, and War to review and grant permits to qualified institutions Requirements that materials, if excavated, be permanently preserved in public museums Authority to develop uniform rules and regulations for implementing the Act The legislation placed the preservation of public lands, water, scientific and scenic sites firmly within the federal government's responsibility and the public's interest. Federal land-management agencies must protect these sites because of their contributions to advancing scientific knowledge and overall public benefit. Since 1906, presidents have exercised their authority under the Antiquities Act nearly 300 times. Including many iconic National Park locations such as the Grand Canyon (1908) to the more recent National Monuments including Berryessa Snow Mountain (2015) and Chuckwalla and Sáttítla (2025) . The Antiquities Act's preservation mandates have generated substantial economic benefits. National monuments create jobs, enhance communities, and strengthen local outdoor recreation economies, which contributed $639.5 billion to national GDP in 2023 . According to the National Park Conservation Association, regions surrounding national monuments also experience growth in employment and increased per capita income following monument designation, demonstrating their positive impact on communities. The national park system attracts nearly 300 million visits to National Monuments and Parks each year, contributing to approximately $30 billion in economic activity. Each dollar invested in park operations yields $10 for local communities. Across party lines, public opinion strongly supports National Parks and Monuments based specifically on their economic impact, with 75% of voters believing public lands attract high-quality employers and jobs to their states, and 80% agreeing these lands support their economy and quality of life. This economic-focused support is distinct from the even broader 95% voter approval for federal management of public lands , which considers additional scientific and recreational benefits beyond economic factors. Efforts to undermine The Antiquities Act contradict public opinion and would compromise its fundamental purpose—enabling presidents to act swiftly in protecting sensitive federal lands. Anti-Antiquities Act activities could expose unique federal lands to development and mining claims, degrading resources and redirecting economic benefits from public to private entities. While The Act provides designation authority, it does not automatically establish management plans, programs, or funding for designated monuments. This is why Tuleyome’s ongoing work with local communities is crucial. Tuleyome collaborates with the public and communities connected to Berryessa Snow Mountain National Monument to develop co-management plans that protect these special places while considering both land preservation and public interests.

Donor Spotlight - Mackenzie

By Nate Lillge • February 6, 2025

I learned about Tuleyome in 2006 when I met staff and the Board at a workshop. Their passionate volunteers were sharing information about their work throughout the Northern Inner Coast Range. I'm thankful for groups like Tuleyome who advocate for our public lands and all user groups. As an avid hiker, I appreciate their commitment to trail building and maintenance as well as the Boot Bank. My first donation to Tuleyome was motivated by their work to protect the Berryessa Snow Mountain region as a National Monument. I was impressed by their innovative approach to addressing environmental issues while engaging diverse stakeholders. I know how important it is for organizations like Tuleyome to receive unrestricted support. The advocacy isn't as effective if the staff don't have the resources to do their vital work. I'm happy to donate so Tuleyome can use the funds where they are needed most, enabling them to respond quickly to changing circumstances and emerging needs. Tuleyome's efforts have significantly enhanced the protection and accessibility of the northern Inner Coast Range mountains. This is key to ensuring the preservation of its unique ecological, recreational, and cultural values for current and future generations. Thank you Tuleyome for all you do!

Monumental Questions - Can I still get Poison Oak in the Winter?

By Kristie Ehrhardt • February 6, 2025

YES! Leaves of three - let them be. Right but it’s winter and what if there are no leaves? Poison Oak ( Toxicodendron diversilobum ), Pacific Poison Oak or Western Poison Oak is a widely distributed woody shrub or vine that belongs to the Sumac (Anacardiaceae) family. The Sumac family is also known as the Cashew family which contains the tree that gives us that delightful buttery nut (it’s actually a seed) as well as the tree that provides mouthwatering mangos and the tree that produces savory pink peppercorns. How can such a delectable family also give us such an annoying plant? Poison oak (PO) is not even remotely related to oaks but the leaves sort of resemble oak leaves. They are divided into three leaflets that are about one and a half to four inches long. The species name, diversilobum, refers to the diversity of leaf size and shape; the edges can be toothed, scalloped or lobed and vary greatly. PO is deciduous and the new leaves are usually dark golden or bronze when they are just beginning to unfold in early to mid-spring. They turn a bright then darker glossy green and ultimately transitioning a stunning scarlet red then fading to pink in late summer and fall. The small flowers are greenish-white and appear in late spring to mid-summer and if they are fertilized they become small creamy white berries. Growth forms vary depending on where it is occurring, but it thrives in full sun as well as shady environments. In open sunlight it can grow as a tall, dense shrub or tree with a thick trunk, or a woody vine winding around and up into the canopy of tall trees, fences and other vegetation. In shady areas it can occur as a dense thicket, vine or anything in between. It is prolific and spreads by seed dispersal and through underground rhizomes. It is widely distributed in Western North America from British Columbia, Washington, Oregon, California, Nevada and Baja Mexico and occurs extensively throughout the Berryessa Snow Mountain National Monument. It occurs in chaparral and woodland habitats as well as coastal sage scrub, grasslands, oak woodlands and mixed evergreen forests below 5,000 feet. It’s a common understory plant in riparian corridors and grows alongside Giant and Coastal Redwoods. PO is even a constant quagmire in dry-farmed mountain orchards, urban parks and recreation areas. In fact, it’s kind of hard to find a biome in the Central Valley of California that doesn’t support Poison Oak unless you go into the Great Basin or the southwestern edge of the Mojave desert. The genus Toxicodendron contains many plants that cause allergic reactions. The oil of the plants contains a compound called Urushiol that causes the reaction and it is found in all parts of the plant except the pollen (ironic!). Direct contact with the plant or anything that has touched the plant such as clothing, pets, tools or vehicles can result in painful, itchy blisters. Not everyone is allergic to it, however, repeated exposure can lead to heightened sensitivity. If an area dense with PO is burning, inhaling the smoke can cause a severe internal reaction. Which leads me to why you can still have a reaction to PO in the winter after all the leaves have fallen. It’s a lot harder to spot when it’s just a twig, branch or bare vine along the edge of the trail. Twigs and stems still contain the oil that produces reactions and you may not even realize that you’ve brushed up against it until it’s too late. Keep an eye out for exposed, reddish-brown whip-like sticks coming out of the ground, especially if you know you’re in an area where PO is present. Sometimes the berries remain on the plant even though the leaves have fallen off and occasionally the stems show black marks where the sap may have oozed out and dried. If you know you’ve been in contact with PO, washing your exposed skin with dish soap is a great way to remove the oil from your skin and washing your clothes as soon as you can so you don’t transfer the oil to yourself, others or additional laundry is also a good idea. If your pets have been scampering about where PO could be present, give them a good bath before you snuggle up with them and consider wearing long rubber gloves like those made for doing dishes to avoid the oils transferring to you. PO isn’t all bad; Black-tailed Deer, California Ground Squirrels and Western Gray Squirrels among other species consume the leaves of the plant which is rich in phosphorus, calcium and sulfur. Many birds eat the berries and utilize the plant for shelter. Research has shown that livestock, domestic dogs and other native wildlife species do not have adverse reactions to Urushiol. Native Americans cooked with it, used the stems to make baskets and used the juice from the fruit to dye materials black. Don’t stay off the trail, just take precautions and enjoy winter hiking in your favorite monument! -Kristie Ehrhardt ( kehrhardt@tuleyome.org ) Tuleyome Land Conservation Program Manager
