Letter from the Director

Dear Sedgwick Community,


Happy Holidays! As we reflect on a very challenging and dynamic year, I am truly grateful for all of the support and strength this community has shown.


Thank you for your generous donations which help us recover from the Lake Fire. The research conducted here will help to inform wildfire resilience and recovery throughout the state. Whether it was a financial gift, volunteer hours, or kind words of support; each act supports conservation and scientific inquiry.


We hope you will join us as we watch the land transform and reveal surprises from the seed bank! As we plan for another engaging year ahead, please consider supporting us. 


With Gratitude,


Dr. Heather Constable

Reserve Director

Shane Dewees studies how fire affects oak photosynthesis

The La Kretz Center is supporting a number of projects focused on the fire ecology of our local oaks, including coast live oak, blue oak and valley oak. For example, Kaili Brande is completing Ph.D. research at UCSB's Bren School documenting how fire impacts on oaks vary depending on oak species, tree size, and bark thickness. Associate Professor Dan Sousa and his students in the Geography Department at San Diego State University are comparing remote sensing imagery obtained from drones, aircraft and satellites for mapping fire effects on oak canopy damage and recovery from fire. Shane Dewees - who recently obtained his Ph.D. at UCSB's Department of Ecology, Evolution and Marine Biology (EEMB) and is now a research scientist at UCSB's Earth Research Institute - is looking at fire effects on oak health from a more physiological perspective.


With the assistance of talented undergraduate research assistant Brooke Ryan, Shane is studying how prescribed fires affect the ability of oak trees to transport water from their roots to their leaves for photosynthesis immediately after a fire. It is a challenging question to answer! First, he has to monitor how selected trees inside and outside of the burn unit are using water immediately before the fire. He then measures canopy heating during prescribed fire using small thermometers hung like ornaments in the outer branches of the oaks. After the fire he compares water transport of unburned oaks to oaks that experienced different levels of canopy heating during the fire. He expects that oaks that receive more heat will suffer more damage to their water transport system. Even if these oaks were not killed or heavily scorched by the fire, they may be more vulnerable to water stress or additional heat stress in the coming years.


It is an important question as we experiment with bringing more prescribed fire into our foothill landscapes to reduce the risk of severe wildfire in local residential areas. Shane is also monitoring oaks burned in the Lake Fire, along with initiating more experimental fire effects studies at Sedgwick Reserve using small "burn boxes" to study fire effects in oak woodlands and coastal sage scrub ecosystems.

Reserve Feature

ALERTCalifornia Tower installed at Sedgwick to inform public safety and fire sciences

Image 2. ALERTCalifornia Tower at Sedgwick Reserve

A new tower has been installed in the heart of Sedgwick Reserve to capture information about potential wildfires. As part of ALERTCalifornia's network of more than 1,080 monitoring cameras and sensor arrays, Sedgwick Reserve Fire Lookout tower will collect data and provide actionable, real-time information to inform public safety. ALERTCalifornia’s high-definition cameras are able to pan, tilt, zoom and perform 360-degree sweeps approximately every two minutes with 12 high-definition frames per sweep. The cameras also provide 24-hour monitoring with near-infrared night vision capabilities. Each can view as far as 60 miles on a clear day, and 120 miles on a clear night. Using the cameras and associated tools, first responders with the California Department of Forestry and Fire Protection (CAL FIRE) can rapidly confirm fire ignition, quickly scale fire resources, support evacuations through enhanced situational awareness and monitor fires through containment. 


The statewide network is run out of the University of California- San Diego and was started with a National Science Foundation (NSF) funded grant titled High Performance Wireless Research & Education Network (HPWREN). It was even named one of Time’s best innovations for 2023. In addition to the camera network, and in response to increasingly frequent and severe climate-driven disasters, ALERTCalifornia is prioritizing novel data collection and research. These data are open-source and are shared with fellow institutions and partners. Using AI technology, the cameras can help with early detection of wildfires and fire behavior. ALERTCalifornia is creating a virtual dashboard to inform fuel reduction efforts year-round and more efficient firefighting during peak fire season to save lives as well as protect habitats and infrastructure. 


The tower was installed on a ridgeline between Lisque Canyon and Figueroa Creek Road, chosen for its vantage point with a direct internet signal from Santa Ynez Peak. Sedgwick staff broke ground on the project in the beginning of June, after a very wet winter and spring turned the access road to mud and delayed the project. A 4 x 4 x 4 foot hole was dug by an auger and by hand. Over 160 bags or 9,600 lbs of concrete were needed for the tower footing to withstand the strong winds on the hill. The tower is solar powered and runs off of twelve 12-volt batteries and a solar array. In consultation with founder Dr. Frank Vernon and the HPWREN Team, Sedgwick staff including Anthony Nelson, Angela Giordani, Lyza Johnsen, Logan Davis, Valentine Navarro, Gary Nett, and Sam Spaulding, worked tirelessly to install the tower over the course of the summer and fall. 


Now officially connected to the statewide network, Sedgwick's ALERTCalifornia tower, which we warmly call "Sofi", was made possible by donor support, with contributions from over 20 individuals. The fundraising effort was motivated by a generous donation from Sedgwick neighbor and supporter, Bert Cohen, who creatively put out a matching challenge to Sedgwick friends and neighbors to secure the funding needed for the tower and associated installation. 


To watch Sedgwick's cameras online go to the ALERTCalifornia website and type in Sedgwick Reserve Fire Lookout on the OPs tab.

Stewardship

In 2024, Sedgwick Reserve hosted a prescribed burn training in collaboration with 54 organizations

Sedgwick Reserve hosted a third annual Prescribe Burn Training Exchange, the Santa Barbara TREX November 9th - 18th, 2024. Sixteen acres of the Sedgwick vegetation management plan areas were treated.


The goals of the burn were:

  • Reduce fuels next to homes and structures
  • Provide education and training opportunities
  • Facilitate indigenous and cultural activities
  • Research the physical and ecological effects of fire
  • Reintroduce small scale low intensity burns to the ecosystem


Funding was provided in part by the Collaboration of Native Nations for Climate Transformations and Stewardship (CNNCTS).
