Williams Ecological Assessments and Planning is the brainchild of Andrea Williams. Known for relentless logic, creative thinking, and botanical skill, Andrea's career showcases examples of protocols, presentations, reviews, and collaborative projects typical of the strong work WEAP provides.
Summary of Work
Key examples of experience, certifications, and work products in a printable one-page document
California State Parks, Sonoma-Mendocino Coast District needed a way to align work in natural resources for its Armstrong Redwoods State Natural Reserve and Austin Creek State Recreation Area Units. WEAP facilitated a process in 2024 incorporating staff input, identified key resources and stressors, built a project prioritization tool and five-year work plan, and made recommendations for goals and additional work to maximize program effectiveness.
The Golden Gate National Parks Conservancy needed a thought partner and an ecologist with local knowledge to provide input on several phases of natural resource vulnerability work. WEAP continues to review documents, attend meetings, and make recommendations around priority taxa, systems, and actions under a resist, accept, or direct framework for management response to climate change.
East Bay Regional Park District engaged WEAP for two projects in 2025, one on invasive plants and one on locally rare plants and vegetation, to prioritize species and near-term actions to maximize resource protection.
Marin Water's rare plant inventory hadn't been updated in nearly 30 years. Compiling several seasons of field work into a clear document with objective local status, trend, and management information allowed prioritization of limited resources to where they could have the greatest impact.
How do you measure the health of a mountain? In 2015, One Tam member organizations set out to answer that question. Andrea served on the Technical Advisory Committee and as main author for several vegetation chapters of the final report; helped facilitate staff and expert stakeholder meetings to review indicators, thresholds, status and trends for ecological land health on Mount Tamalpais, Marin County, California. Reviewed and revised the 2023 Open Canopy Oak Woodlands chapter as well.
In 2015, the California Native Plant Society needed help working through a strategic planning process. Andrea's work, from a large-group facilitated SWOT analysis to targeted meetings and editing sessions, helped bring the project to fruition.
Fuel reduction, invasive plant control, sudden oak death response, and other land management and monitoring need to be planned in concert for best effect. Andrea worked on a team of staff and consultants to produce a vegetation management plan for weed control, fuelbreaks, and biodiversity monitoring on watershed lands. The plan identified stressors such as disease, climate change, and invasive species as well as management objectives, priority habitats, and costs associated with each action.
While at Marin Water, served on the Asset Management Steering Committee and gained certification in Asset Management Planning, producing an asset management plan for fuelbreaks on watershed lands. The asset management process identifies objective metrics for risk and condition assessment; determines maintenance, replacement, or improvement needs and costs; and builds a calendar and shows tradeoffs in risk and responsiveness based on resources given to operations and capital budgets.
What are the priority invasive plants and places in Bay Area National Parks? Andrea worked with vegetation specialists from Golden Gate National Recreation Area, Point Reyes National Seashore, and Pinnacles National Monument (now Pinnacles National Park) through a years-long meeting, editing, and testing process to create a comprehensive, documented process to prioritize species and areas for searching and levels of mapping required for a thorough invasive species early detection program.
Andrea has served on boards and in leadership since the 1990s, including the California Native Grasslands Association, California Invasive Plant Council, Calflora, and numerous internal advisory and steering committees. Trained as a facilitator through NOAA's "Navigating in Rough Seas" workshops, and skilled at incorporating structured decision-making methods and creating process agendas to have clear, shared objectives and expectations.
Created curriculum for "Apps and Snaps" field course covering computer- and smartphone-assisted plant identification, mapping and tracking; regular instructor for grass identification courses; developed "How to Cheat at Botany" offering tips and tricks on plant identification for all skill levels. Most familiar with plants of Coastal and Northern California but able to identify or train others on plants of the California Floristic Province.
From a full-day workshop to a section in an introductory course, trainings on ways to plan for efficient weed management can be tailored to your needs.
Initial work on ecological indicators with the National Park Service's San Francisco Bay Area Inventory and Monitoring Network led to innovative projects such as the botanical inventory of Marin Water lands and the Peak Health Report. If you need help choosing indicators of land health, adding participatory science as a line of inquiry or evidence, or working through monitoring ideas, WEAP can help.
