Generalised anxiety and chronic stress Strong
Consistent effects on self-reported anxiety and autonomic markers (HRV, cortisol). Outdoor setting directly addresses sensory over-stimulation that commonly maintains anxiety.
Format: Individual, weekly or fortnightly, 6–10 sessions before reassessment.
Pocket guide activities: Sit spot, forest breathing, sensory mapping.
Combines with: CBT (behavioural experiments with graded exposure); somatic approaches for interoceptive work.
Burnout and occupational exhaustion Strong
Particularly strong results where exhaustion is accompanied by depletion of directed attention. Low-demand early sessions that permit rest counter the productivity bias sustaining the condition.
Format: Individual, fortnightly, 8–12 sessions; longer timeframe than anxiety work.
Pocket guide activities: Sit spot, silent paired walk, weather dialogue.
Combines with: ACT for values clarification; narrative work on occupational identity.
Mild-to-moderate depression (non-psychotic) Moderate
Evidence strongest for depression with behavioural withdrawal and anhedonia components. Movement through natural environments supports activation without the demand characteristic of structured exercise prescriptions.
Format: Individual, weekly, 8–12 sessions. Assess motivation for outdoor engagement before committing.
Pocket guide activities: Threshold walk, roots & branches, bark rubbing & texture journal.
Combines with: Behavioural activation; medication management; narrative therapy for meaning-making.
Adolescent emotional and behavioural difficulties (non-acute) Moderate
Outdoor context lowers resistance typical of adolescent presentations: reduces face-to-face pressure, normalises movement and silence, side-by-side dialogue feels less clinical. Group formats leverage peer-relational dynamics.
Format: Individual or small group (4–6), weekly, 8–12 sessions. Parent/carer communication protocol agreed in advance.
Pocket guide activities: Threshold walk, tracking & noticing, forest mandala.
Combines with: CBT-adapted approaches; systemic family work; school liaison where indicated.
Attention difficulties (ADHD profile) Emerging
Attention Restoration Theory predicts direct benefit; emerging evidence supports this for both adults and children. Particularly useful as adjunct to stimulant treatment for non-pharmacological skill development.
Format: Individual or group, shorter sessions (45–60 min), weekly, 6–10 sessions. Pharmacological treatment continues unchanged.
Pocket guide activities: Tracking & noticing, sit spot, forest breathing.
Combines with: Ongoing ADHD pharmacotherapy; executive function coaching.
Grief and bereavement (post-acute phase) Moderate
Not for acute grief. For post-acute grief work — typically 3+ months after loss — nature provides structural metaphors (cycles, decay as generative, seasons) that complement narrative reconstruction of the bereaved's relationship with the deceased.
Format: Individual, fortnightly, 6–10 sessions. Longer if complicated grief.
Pocket guide activities: Dead wood dialogue, threshold walk, tree council.
Combines with: Continuing-bonds frameworks; narrative therapy; meaning reconstruction approaches.
Trauma recovery (post-stabilisation only)
FBT may support integration work once trauma has been stabilised through trauma-specific approaches (EMDR, CPT, phased trauma therapy). Never a primary trauma treatment. Requires specific training in trauma-informed practice.
Required before use: Stabilisation phase complete; participant's window of tolerance mapped; trauma-informed practitioner competency; clear containment protocol if activation occurs outdoors.
Attachment and relational work
Paired and small-group formats can surface relational patterns with less defensive structure than indoor settings. Silent paired walks, tree council work, and shared-task activities generate relational material.
Required before use: Formulation of relational difficulty; established therapeutic relationship; competence in working with enactments.
Identity and life-stage transitions
Strong fit for transitions where orientation rather than symptom reduction is the goal. Threshold metaphors, walking structures, and tree-as-structure work are directly generative. Less symptom burden usually means shorter engagements.
Required before use: Clinical formulation distinguishing transition work from underlying mood, anxiety, or personality disorder presentations.
Family and couples work
Outdoor setting disrupts entrenched interaction patterns. Activities requiring cooperation or shared attention externalise relational dynamics in ways that room-based work often cannot.
Required before use: Systemic/couples therapy training; clear contracting around confidentiality between partners; safeguarding screen (IPV, child protection).
Dissociative presentations
Natural environments can both ground and trigger dissociation. Outcomes depend critically on the practitioner's competence in working with dissociation, not on the setting. Without that competence, FBT is contraindicated for this presentation.
Complex PTSD with possible nature-related triggers
Trauma history involving nature (outdoor assault, disaster, childhood neglect involving being left outside) requires specific assessment. The forest is not neutral. Screen explicitly before proceeding.
Recent suicidal ideation (stabilised)
FBT is not contraindicated in recent (not current) suicidality if stabilisation is established. However, remote-setting risk considerations (access to means, phone signal, extraction time) require explicit planning and shared with the participant.
Severe personality disorder presentations
Particularly for presentations with intense transference/counter-transference dynamics. The informality of outdoor settings can blur frames in ways that destabilise therapeutic boundaries. Requires supervision specifically competent in this work.
