The Profession  of Landscape Architecture should  definitely continue to  be licensed and regulated because Landscape Architects , myself included,  often lead or are  involved in projects that affect public safety and welfare such as 

---planning large scale projects such as large campuses, urban districts, land holdings,  and parks that affect human welfare and safety, determine environmental issues, and  coordinate with watersheds of scale. 

--- grading and drainage plans that impact watersheds and mitigate local flooding and erosion.

--- vehicular and pedestrian routes  (including service and fire routes  and taking into vehicular account sight-line issues )

--- Public and institutional spaces that must meet requirements for public safety and policing .  

---Paved Spaces and ramps that require safe passage and ADA compliant design 

---Outdoor structures such as pavilions and walls that require sound design. 

--Lighting plans for safe passage at night .
