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.

Women's Equality Day 2026

By Kristie Ehrhardt • August 26, 2026
The 19th Amendment to the Constitution - granting women the right to vote - was certified on August 26, 1920. In commemoration of this, in 1973 Congress designated August 26 as "Women's Equality Day" to remind us of the heroic women who advanced the Women's Suffrage movement. In recognition of Women's Equality Day, Tuleyome is highlighting three women who are dedicated to conservation: Sheila Pratt (Cache Creek Conservancy), Corky Quirk (NorCal Bats and Yolo Basin Foundation), and Cathy Little (Yolo Habitat Conservancy). Please share in a round of applause for our friends for their passion and dedication to conservation.

Women's Equality Day 2026 - Cathy Little

The 19th Amendment to the Constitution - granting women the right to vote - was certified on August 26, 1920. In commemoration of this, in 1973 Congress designated August 26 as "Women's Equality Day" to remind us of the heroic women who advanced the Women's Suffrage movement.

Hear about Cathy's journey below and learn about Sheila here and Corky here. Please share in a round of applause for our friends for their passion and dedication to conservation. I received my Bachelor’s Degree at UC Davis in Plant Biology and immediately moved into environmental consulting when I graduated. For the next few years, I had the opportunity to botanize and see lands throughout California. I was working on large river projects and became interested in restoration of riparian habitat and decided to go back to school and get my master’s degree at Chico State. I continued working on restoration projects and started to be more interested in conservation work. I spent the last 16 years working for the Center of Natural Lands Management where I directly managed and acquired lands with listed species and sensitive habitats and led the northern California group. Recently I made a career move to the Yolo Habitat Conservancy where I am now contributing to conservation work in my local County. Through growing up in California I have been able to spend a large amount of time in vast beautiful wilderness areas, but have also witnessed conversion of many lands to development. I have always had a draw to natural lands and observing the amazing intricate ecosystems that they support. When I was working in environmental consulting on designing, building, and monitoring restoration sites, I saw these lands being transferred to entities that managed them in perpetuity, and I knew that I wanted to be part of the effort. I have spent most of my career now doing just that. Throughout my time working in conservation, I have had so many long-term field ecologists inspire me to continue doing this work. Watching others work tirelessly over many years to manage and protect natural lands, and collaborate and share their knowledge, has been so motivating. There is nothing more enjoyable than spending a day in the field with other ecologists and sharing enthusiasm about some small moment of observation, and always learning some new tidbit of information about a certain species or behavior or management tool. My advice to young women starting their career in the environmental/conservation/non-profit sector would be to just get out there and start gaining experience in whatever seems interesting and then collaborate and talk to as many people to learn about all the different opportunities. There are so many aspects of conservation and environmental work and the more time you spend working in it, the more you will be able to figure out how you want to contribute to the community as a whole. I would suggest taking as many opportunities as you can and working with as many different people as possible. Listening to people’s backgrounds, experiences, and perspectives can be valuable in navigating your path. I would recommend always advocating for yourself, being open and honest about your abilities, and committing to and communicating your beliefs regarding your work.

Women's Equality Day 2026 - Corky Quirk

I have been involved with outdoor recreation and environmental education most of my life. I have a BS in Natural Resources with an emphasis in Environmental Education from Humboldt State. But, it was learning about them at the Yolo Basin Foundation (YBF) where I found my love for bats. When I started at YBF, there was a woman who we contracted to do 3 programs a summer and I started volunteering for her organization in 2004. I was inspired to work in the conservation/preservation/ecology sector because my parents loved nature. We did many trips to State and National Parks where we camped and hiked. Over the years I have met many people who work in the conservation field and have encouraged me. I greatly enjoy sharing knowledge with the various bat biologists from environmental consultants, to the State to the US government agencies. There are two projects that I am most proud of. I started NorCal Bats in 2006 and now see almost 40,000 people each year to educate them about bats from schools, libraries, garden clubs, festivals, campgrounds and more. I'm also very proud of how popular the Yolo Basin Foundation Bat Talk and Tour program has become. When I took over the program in 2006 we did about 3 nights a summer, now we are conducting about 70. Some of the most profound moments and memories for me are of all the people who have learned about bats both through the Yolo Basin Foundation's Bat Talk and Tour programs and the presentations through NorCal Bats. I don’t have a specific favorite memory but I am proud of the number of times people come to me and say that they were hesitant or afraid of bats, and no longer are due to the presentation. Periodically, when I take the bats to schools through NorCal Bats, I'll have a student who is very fearful. Sometimes they hide under a desk or sit very close to the teacher. I'm most proud when they overcome that fear, ask questions and especially if they say that the bat is cute.
