Understanding the experiences of blind, deaf, and deaf-blind individuals in botanical gardens

Key Findings

  • Multisensory engagement is paramount for meaningful experiences
  • Tactile and audio stimuli are essential for blind visitors
  • Sign language interpretation crucial for deaf accessibility
  • Co-creation with disabled communities drives true inclusion

Blind, deaf, and deaf-blind individuals face significant challenges in botanical gardens, primarily related to navigation, information access, and communication. Their expressed needs consistently emphasize the desire for multisensory engagement, particularly through audio and tactile stimuli for blind visitors, sign language interpretation and visual cues for deaf visitors, and facilitated tactile experiences with Protactile communication and guide support for deaf-blind visitors.

Their emotional responses range from joy and connection when these needs are met, to frustration and exclusion when they are not, highlighting the critical importance of inclusive design and practices in these natural spaces.

Understanding the Diverse Needs of Visitors with Sensory Impairments

The Importance of Inclusive Design

Inclusive design in botanical gardens is paramount to ensuring that these natural sanctuaries are welcoming and enriching for all visitors, regardless of their abilities. The core principle is to create environments that can be accessed, understood, and used to the greatest extent possible by all people, without the need for adaptation.

By proactively considering diverse experiences, botanical gardens can transform from potentially exclusionary spaces into places of discovery, learning, and enjoyment for everyone. The benefits include increased visitor numbers, enhanced visitor experience, improved reputation, and compliance with accessibility laws.

Overview of Challenges

Blind & Visually Impaired

  • • Navigation and wayfinding difficulties
  • • Uneven pathways and lack of tactile cues
  • • Inaccessible information formats
  • • Limited social interaction opportunities

Deaf & Hard of Hearing

  • • Communication barriers with staff
  • • Lack of sign language interpretation
  • • Missing visual cues for environmental sounds

The Blind and Visually Impaired Experience

Key Challenges

Blind and visually impaired visitors encounter significant challenges related to navigation, information access, and social interaction. Uneven pathways, unexpected terrain changes, and lack of consistent tactile or auditory wayfinding cues make independent exploration difficult and potentially unsafe.

"Feeling so many different forms and so many different textures, something I never think. Flowers feels like flowers… The different textures help me to remember which each of these is, especially without the visual memory obviously"

— BPS participant in multisensory tour study

Expressed Needs

  • Enhanced audio stimuli: Detailed audio descriptions and natural garden sounds
  • Tactile experiences: Opportunities to touch plants, leaves, bark, and soil
  • Proactive guiding: Empathetic guides facilitating safe exploration

Personal Narrative: Helen Keller's Connection

"The people who imagine I am shut out from nature do not dream of the world of loveliness that touch and the sense of smell reveal to me... I have the sun and the cool shade, the morning dew upon bush and grass, the stillness of eve—all sweet things—the graceful ferns and a wealth of flowers"

— Helen Keller

Keller described her garden as her "greatest joy" and felt "in the seventh heaven when among my plants," illustrating the profound connection possible through non-visual senses.

The Deaf and Hard of Hearing Experience

Communication Barriers

Deaf and hard of hearing individuals face distinct challenges primarily stemming from communication barriers and difficulty accessing auditory information. Guided tours and educational programs are frequently conducted without sign language interpretation or real-time captioning.

Key Challenges

  • • No sign language interpretation for tours
  • • Staff untrained in basic sign language
  • • Lack of visual cues for environmental sounds
  • • Inaccessible audio guides and presentations

Impact

  • • Exclusion from educational content
  • • Fragmented garden experience
  • • Social isolation in group settings
  • • Limited ecological understanding

Expressed Needs and Solutions

Sign Language Interpretation

New York Botanical Garden offers ASL-interpreted tours of its Perennial Garden, while the Brooklyn Botanic Garden provides ASL-led workshops specifically designed for the d/Deaf community.

Visual Information

Clear signage with text and symbols, visual representations of sounds, captioned videos, and accessible digital materials are essential for independent navigation and learning.

Effective Communication Strategies

The "COME IN! - BOTANICAL GARDEN" methodology emphasizes:

  • • Always face the person and maintain eye contact
  • • Speak clearly with natural pace and lip movement
  • • Use gestures and facial expressions when appropriate
  • • One person speaks at a time
  • • Pause for interpreter delays

The Deaf-Blind Experience

Profound Challenges

Individuals who are deaf-blind face a unique and profound set of challenges stemming from the combined loss of sight and hearing. This dual sensory deprivation significantly impacts their ability to navigate, access information, and communicate, making independent exploration exceptionally difficult.

Navigation

No visual or auditory cues for wayfinding, requiring tactile paths and guide support

Communication

Need for Protactile communication and trained support service providers

Experience

Limited opportunities for safe and meaningful tactile exploration

Critical Needs

Tactile Experiences

Deaf-blind individuals express a strong need for rich, accessible tactile experiences. This includes plants with diverse textures, varying temperatures, and distinct shapes and sizes. Raised garden beds make plants more accessible for touching.

  • • Safe tactile exploration areas
  • • Plants with diverse textures (soft, rough, smooth, fuzzy)
  • • Access to soil, leaves, bark, and flowers
  • • Clear guidance on safe touching

Protactile Communication

Protactile communication is a vital language that relies on touch. Gardens need staff trained in Protactile communication or visitors accompanied by their own Protactile interpreters.

The Deafblind World workshops demonstrate the importance of direct, accessible communication and sharing lived experiences.

Guide Support

Essential support from trained garden staff, volunteers, or personal care attendants who are sensitive to communication preferences and pace. Deafblind Community Services organizes visits to sensory gardens during Deafblind Awareness Month.

Emotional Significance

For deaf-blind individuals, emotional responses are deeply intertwined with sensory experiences available through touch and smell. When gardens are designed to be tactilely and olfactorily rich, they can evoke profound feelings of joy, wonder, and connection to nature.

A teacher who built a sensory garden with students, including those with deafblindness, described it as "awesome with inspiring creativity, understanding, calmness, recreation and concept development".
