The establishment and maintenance of street tree planting is generally a 2-year period for newly planted trees. This involves data entry and record keeping of all trees planted, including continual updates and assessment of the health of each individual tree. This data is fully accessible and provides invaluable information and history of each tree and its area. SEVRON along with our local government clients are committed to ensuring that the trees we plant are healthy, well maintained and become well established for the future.
