Trail Selection Methodology

How we identify trails with potential for measurable wellness outcomes

Our Research Philosophy

As a nature-based health research company, we don't choose trails based on popularity or scenic beauty. Instead, we systematically identify locations where peer-reviewed science suggests measurable health benefits are achievable through accessible outdoor experiences.

Every research site in our growing library is selected through evidence-based evaluation: Does this trail environment contain the conditions that scientific studies have linked to documented health benefits?

We seek trails that offer what modern life depletes: environments where research suggests stress reduction, cognitive restoration, immune system enhancement, and circadian reset are possible—all based on peer-reviewed evidence.

Selection Framework

The Five Research Criteria

Every research site must demonstrate strong potential in these evidence-based areas:

1. Physiological Health Potential

  • Presence of phytoncide-producing tree species (cedar, oak, pine) documented in immunity studies

  • Water features that generate negative ions linked to mood enhancement in research

  • Variable terrain shown to activate proprioceptive systems in balance studies

  • Light exposure conditions that research connects to circadian regulation

2. Cognitive Health Environment

  • "Soft fascination" landscapes proven in studies to restore attention capacity

  • Natural soundscapes in research-validated ranges (40-50 decibels) for stress reduction

  • Visual complexity that research suggests engages without overwhelming

  • Navigation elements that studies show stimulate spatial cognition

3. Sensory Documentation Opportunity

  • Distinct seasonal variations that allow comprehensive experience mapping

  • Flora/fauna diversity that provides rich sensory engagement documented in research

  • Environmental conditions that enable detailed documentation of therapeutic encounters

  • Accessibility for comprehensive sensory experience recording

4. Research Alignment

  • Trail conditions that match environments used in peer-reviewed wellness studies

  • Accessibility that allows diverse populations to experience research-validated benefits

  • Consistent environmental factors that research suggests deliver reliable outcomes

  • Minimal confounding variables that could interfere with research-supported benefits

5. Scientific Evidence Base

  • Environments that align with published study parameters for nature-based health benefits

  • Conditions documented in research as producing measurable wellness outcomes

  • Settings where existing studies suggest specific health improvements are achievable

  • Potential for future research validation of documented benefits

Research Process

Phase 1: Literature Review & Site Identification

Scientific Research Analysis

  • Review of peer-reviewed studies on nature-based health interventions

  • Identification of specific environmental factors linked to wellness outcomes in research

  • Documentation of optimal exposure conditions found effective in published studies

  • Analysis of replicable protocols from established research

Geographic Assessment

  • Identification of ecosystems that match research study environments

  • Assessment of regional biodiversity and therapeutic plant species presence

  • Evaluation of geological features that research links to health benefits

  • Climate analysis for conditions shown effective in scientific studies

Phase 2: Evidence-Based Site Evaluation

Each potential research site undergoes assessment using our TRAIL-R Framework:

T - Therapeutic Environment Potential (25 points)

  • Does this environment match conditions from peer-reviewed wellness studies?

  • Are therapeutic compounds (phytoncides, negative ions) likely present based on vegetation/water features?

  • Do environmental conditions align with research showing health outcomes?

R - Research Documentation Opportunity (20 points)

  • How comprehensively can we document sensory experiences for research application?

  • Are seasonal variations significant enough for ongoing study potential?

  • Does the environment offer rich observation opportunities documented in research?

A - Access & Research Applicability (20 points)

  • Can individuals safely and consistently access conditions shown beneficial in studies?

  • Are trail conditions stable enough for reliable experience documentation?

  • Is the location suitable for research-informed protocols?

I - Immune & Stress Research Alignment (15 points)

  • What tree species present match those in immunity/stress research studies?

  • Are stress-reducing environmental factors (water sounds, forest density) present as documented in research?

  • Do conditions align with environments where immune/stress benefits were measured?

L - Literature-Supported Benefits (20 points)

  • Do published studies suggest this environment type produces lasting health benefits?

  • Does the site offer conditions research shows have ongoing wellness impacts?

  • Can we connect environmental features to established scientific findings?

Phase 3: Site Documentation & Research Application

Research sites undergo comprehensive documentation for research application:

Environmental Assessment

  • Documentation of tree species and vegetation that research links to health benefits

  • Sound environment recording to assess alignment with therapeutic ranges found in studies

  • Air quality assessment to evaluate potential for benefits documented in research

  • Botanical identification of species shown therapeutic in scientific literature

Research-Informed Health Potential

  • Evaluation of conditions research suggests affect cortisol/stress levels

  • Assessment of environments studies show impact heart rate variability

  • Documentation of features research links to sleep quality improvement

  • Identification of elements studies connect to cognitive function enhancement

Comprehensive Experience Documentation

  • Detailed sensory experience mapping based on research-supported therapeutic elements

  • Seasonal variation documentation of conditions shown beneficial in studies

  • Documentation of environmental features research suggests reduce stress

  • Photographic documentation suitable for research application

Selection Standards

What We Prioritize
