Evidence-Based Nature Connection

Tara Tiger Brown, PhD researches how nature supports human health, and puts that evidence into practice through guided programs, trail assessments, and evaluating how AI considers the environment and animal welfare.

From the research

Quiet for us isn’t always quiet for wildlife

Drag the slider to change the noise level on a trail.

42 dBA
Hearing risk for people (NIOSH model: 85 dBA for 8 hours)
PEOPLE AS SOURCES OF NOISE

dBA reflects human hearing and underweights low-frequency sound such as aircraft and fireworks. Hearing-risk times use the NIOSH model: 85 dBA for 8 hours, halving every 3 dBA. Reference ranges on the scale come from empirical field assessments and published studies.

Therapeutic and Sensory Trail Assessments

Measurably support human health. Respect wildlife.

FOR Park managers, urban planners, health authorities, and resort and hospitality groups.

  • Visitor perception and health measures +

    Psycho-physiological outcomes (blood pressure, heart rate, Abbreviated Profile of Mood States (A-POMS), Connectedness to Nature (CNS)) alongside visitor survey feedback on perceived quietness, noise sensitivity, and stress reduction.

  • Microclimate, light, and air quality +

    Mobile cart microclimate logging (temperature, relative humidity, wind speed, Climatic Comfort Index), lux photometer light measurements, and regional and in-situ air quality metrics (PM₂.₅).

  • Acoustic audits and soundscape mapping +

    Decibel logging (dBA), natural versus anthropogenic sound auditing, and identifying quiet refuges within urban park systems.

  • Vegetation structure and wildlife habitat +

    Forest canopy coverage thresholds (minimum 30%), interrupted line transects, 5 × 5 m quadrats, dominant indicator plant species, and habitat preservation.

Talks, Workshops, and Guided Sessions

Forty years of nature-health research, made practical.

FOR Conferences, healthcare systems, academic institutions, and corporate teams.

  • Forest bathing science +

    Translating doctoral forestry research and sensory ecology into practical human restoration.

  • Acoustic ecology in urban planning +

    How soundscapes shape cognitive health, stress reduction, and community flourishing.

  • Human-technology coexistence +

    Examines how digital innovation and AI can reconnect urban populations with nature rather than exacerbate digital fatigue or technostress.

  • Group sessions & PaRx connection +

    Delivers structured group forest bathing sessions connecting clinical prescriptions with therapeutic outdoor practice.

“Tara creates a welcoming, thoughtful space and guides the experience in a way that feels natural and unhurried.” Sean Graham, Participant

Artificial Intelligence & Wild-Animal Welfare Evaluations

AI assistants now advise millions of visitors seeking quiet trails, but human quiet is not animal welfare.

FOR AI research labs, outdoor platforms (e.g. AllTrails), conservation tech teams, and park agencies.

  • Field-grounded model evaluations +

    Testing how language models and consumer assistants advise on trails and natural spaces, scored against empirical field acoustic data.

  • Welfare benchmarks and safeguard design +

    Measuring omission, hallucination, and the impact of evidence briefs so models don’t mistake human calm for ecological safety.

  • Research co-authorship and advisory +

    Ground-truthed validation using 17 urban and peri-urban forest trail audits from the Silent Trails project in Metro Vancouver Regional Parks.

Doctoral research at UBC Faculty of Forestry & Environmental Stewardship

Field-tested methods for restorative greenspace

My doctoral research developed a standardized methodology for evaluating forest trails as therapeutic landscapes, examining acoustic thresholds, microclimate comfort, vegetation density, and psycho-physiological recovery. I apply these learnings to my guided sessions and assessments.

PROFESSIONAL EXPERIENCE

From tech to trees

Before earning my PhD at UBC, I spent 15+ years in tech and education leading software projects for Microsoft, building platforms that helped musicians reach fans directly, and developing learning products with research labs at USC and UC Irvine.

Now I bring those worlds together through programs, field assessments, and evaluating how AI handles natural spaces and where human field observation is still needed.
