The Dolder Grand is nestled in the Adlisberg Forest \u2013 a location that not only attracts guests but also entails an ecological responsibility. The double materiality analysis has confirmed that biodiversity and ecosystems are a material issue for Dolder Hotel AG \u2013 both in terms of our impact on the environment and with regard to financial risks: our business operations depend on intact ecosystems \u2013 from the natural landscape that shapes the guest experience, through the hillside vegetation that provides erosion control, to the availability of high-quality food and nature-based materials in the supply chain.<\/p>\n\n\n\n

At the same time, we make an active, positive contribution: with around 20 hectares of green space \u2013 including around 13 hectares of our own woodland, a spacious park, extensively greened roof areas and the garden of the Restaurant blooms \u2013 we maintain and manage biodiversity areas that contribute directly to urban biodiversity on the Z\u00fcrichberg.<\/p>\n\n\n\t\n \n\t \t\t \t\t\t\t\t\n\n\"\"\n\t\t\t<\/picture>\n\t <\/div>\n\n\n\n

Forest.<\/strong> The hotel borders directly on a vast forest area that provides a valuable habitat for numerous wild animals: roe deer, foxes, badgers, martens, polecats, crows, jays and tawny owls are native to this area. In close cooperation with \u201cGr\u00fcn Stadt Z\u00fcrich\u201d and the relevant gamekeepers, we are committed to protecting this biodiversity.<\/p>\n\n\n\t\n \n\t \t\t \t\t\t\t\t\n\n\"\"\n\t\t\t<\/picture>\n\t <\/div>\n\n\n\n

Park.<\/strong> The park features a carefully curated selection of around 50 different plant species \u2013 ranging from native trees and shrubs such as hornbeam, yew and boxwood to ecologically valuable species such as serviceberry, dogwood and snowball bush, which serve as forage for bees and food sources for birds. Flowering perennials such as lavender, sage and agastache complement the range of options for pollinators. The serviceberry and cornelian cherry exemplify the triad of ecology, cuisine and aesthetics: their fruits are harvested by our chefs and used in the kitchen.<\/p>\n\n\n\t\n \n\t \t\t \t\t\t\t\t\n\n\"\"\n\t\t\t<\/picture>\n\t <\/div>\n\n\n\n

The garden of Restaurant blooms.<\/strong> Over 40 different plant species are grown in the hotel\u2019s own garden patches \u2013 including vegetables, herbs, berries and fruit trees. The garden is managed according to ecological principles: mechanical weed control, the use of beneficial insects such as ladybird larvae, night-time watering to conserve water, sheep\u2019s wool pellets as a natural fertiliser, and a strict avoidance of chemical pesticides.<\/p>\n\n\n\n

Green roofs.<\/strong> The roof areas around the photovoltaic system are covered with extensive vegetation comprising 21 native wildflower and sedum species. This measure restores habitat to nature and, through evaporative cooling, simultaneously enhances the efficiency of the solar panels.<\/p>\n\n\n\n

Garden and landscape maintenance.<\/strong> Throughout the outdoor grounds, we rely on sustainable methods: organic products, effective microorganisms, site-appropriate planting and mechanical rather than chemical weed control.<\/p>\n\n\n\n

Together with our commitment to protecting the adjacent woodland \u2013 in partnership with \u201cGr\u00fcn Stadt Z\u00fcrich\u201d and the gamekeepers \u2013 these measures are a concrete expression of our holistic approach to sustainability: protecting nature, promoting biodiversity and preserving habitats for future generations.<\/p>\n\n\n\t\n \n\t \t\t

Bees & Friends \/ Tiny Dolder Grand<\/a>.<\/strong> As part of the \u2018Bees & Friends\u2019 campaign by HotellerieSuisse and Switzerland Tourism, the \u2018Tiny Dolder Grand\u2019 was created in 2025 \u2013 a miniature version of the ballroom, designed by mechanical engineer Josua Gl\u00fcnkin and situated on the edge of the forest. The initiative combines the promotion of pollinator habitats with a playful approach to raising awareness of biodiversity among guests and staff.<\/p>\n\n\n <\/div>\n <\/div>\n\n\n \n

\n \n Goals, ongoing and future projects and initia\u00adtives<\/span>\n \n\n<\/svg>\n<\/span>\n <\/button>\n <\/h3>\n \n \n\n

The existing practices \u2013 the consistent avoidance of chemical pesticides, planting suited to the location, and the partnership with \u201cGr\u00fcn Stadt Z\u00fcrich\u201d \u2013 will be continued and, where possible, expanded. The ecological health of our surroundings is currently good but is vulnerable in the long term to climate-related changes \u2013 in particular droughts, storm damage and the spread of invasive species. Dolder Hotel AG has not yet defined quantitative biodiversity targets for the reporting year.<\/p>\n\n\n <\/div>\n <\/div>\n\n\n \n

The main sites of Dolder Hotel AG are located at Kurhausstrasse 65, 8032 Zurich (The Dolder Grand) and Kurhausstrasse 20, 8032 Zurich (Dolder Waldhaus). The site is situated on the edge of the Adlisberg Forest, within the protection zone of the \u2018Dolderwiese\u2019 spring group, and is served by the Dolderbahn, a rack railway within the Zurich Transport Network.<\/p>\n\n\n\n

The Emerald Network of the Bern Convention \u2013 the protected area instrument at European level that is authoritative for Switzerland \u2013 was used as the basis for assessing biodiversity sensitivity. Both sites were examined within a 5-kilometre radius for proximity to designated Emerald sites. The screening revealed no Emerald sites within this radius.<\/p>\n\n\n\n

In the immediate vicinity lies the Wehrenbachtobel, a cantonal nature and landscape conservation area with its own protection ordinance issued by the Canton of Zurich.<\/p>\n\n\n\n
