The activities of a landscape architect can range from the creation of public parks and parkways to site planning for campuses and corporate office parks, from the design of residential estates to the design of civil infrastructure and the management of large wilderness areas or reclamation of degraded landscapes such as mines or landfills. Later, in 1978, IFLA's Headquarters were established in Versailles. Factors in designing also include subjective qualities such as: genius loci (the special site qualities to emphasize); client's needs and preferences; desirable plants and elements to retain on site, modify, or replace, and available to use as borrowed scenery from beyond; artistic composition from perspectives of both looking upon and being in the *gardens; spatial development and definition; plant palettes in designed layouts, and artistic focal points for enjoyment. The first person to write of making a landscape was Joseph Addison in 1712. The up-and-coming practice of online landscape design allows professional landscapers to remotely design and plan sites through manipulation of two-dimensional images without ever physically visiting the location.
The scope of the profession includes landscape design; site planning; stormwater management; environmental restoration; parks and recreation planning; visual resource management; green infrastructure planning and provision; and private estate and residence landscape master planning and design; all at varying scales of design, planning and management. Through the 19th century, urban planning became a more important need. Every piece of land is unique and offers different materials and microenvironments, ecoscaping aims to design in harmony with the land and create an environmentally healthy and sustainable landscape.
Ecoscaping also strives to take an existing structures and areas (backyards, cities, campuses, etc.) and add ecological balance and greenery. The combination of the tradition of landscape gardening and emerging city planning that gave Landscape Architecture its unique focus to serve these needs. In the second half of the century, Frederick Law Olmsted completed a series of parks which continue to have a huge influence on the practices of Landscape Architecture today. Its distinguishing feature is the marriage of landforms, substrates, and vegetation throughout all phases of design and construction, which previously have been kept as separate disciplines. In the second half of the century, Frederick Law Olmsted completed a series of parks which continue to have a huge influence on the practices of Landscape Architecture today. Landscape engineering builds on the engineering strengths of declaring goals, determining initial conditions, iteratively designing, predicting performance based on knowledge of the design, monitoring performance, and adjusting designs to meet the declared goals. Due to the frequent lack of non-visual, supplementary data such as soil assessments and pH tests, online landscaping necessarily must focus on incorporating only plants which are tolerant across many diverse soil conditions.. It differs from, but embraces traditional reclamation. Some scholars consider Downing to be The Father of American Landscape Architecture, although others choose Frederick Law Olmsted.
