Landscape architects lead the planning, design, and stewardship of healthy, equitable, safe, and resilient environments. With their unique skill set, landscape architects improve human and environmental health in all communities.  While almost 25,000 people work in the landscape architecture field in the United States, over 17,000 are licensed landscape architects.  Licensure is required in all 50 states and the District of Columbia, making landscape architecture one of only around 60 professions to be licensed in all 50 states. Each state sets its own requirements for licensure, based on the three E’s of education, experience, and examination. The licensing process is administered by state licensing boards. All states require candidates to pass the Landscape Architect Registration Examination (LARE), which is administered by the Council of Landscape Architecture Registration Boards (CLARB).

ASLA’s Mission is to lead, to educate, and to participate in the careful stewardship, wise planning, and artful design of our cultural and natural environments.

Our commitment is to serve as a leading professional organization, providing a collaborative platform for landscape architects, allied professionals, and stakeholders to exchange ideas, advance knowledge, and advocate for the importance of thoughtful, innovative, and resilient landscapes.

Through advocacy, education, and outreach, we strive to elevate the profession of landscape architecture, enhance public awareness of its significance, and champion the principles of environmental conservation, social equity, and cultural preservation.

We are dedicated to fostering a thriving and inclusive community of landscape architects, where ideas are nurtured, skills are developed, and collaboration is encouraged, all in pursuit of designing landscapes that respond to the unique challenges and opportunities of Arizona's diverse natural and built environments.

In alignment with the principles of the ASLA, our chapter remains committed to upholding the highest ethical standards, supporting professional growth, and fostering a passion for sustainable design that harmonizes human well-being with the natural world.
