Juhend elurikka linna planeerimiseks

This guide, published by the Stockholm Environment Institute (SEI) Tallinn, provides instructions for planners, developers, and citizens on how to integrate biodiversity into urban planning processes to prevent the loss of species during development projects. It focuses on specific animal groups, the implementation of a 'green space factor' to quantify ecological value, and practical measures for creating urban habitats such as green roofs, vertical greenery, and sustainable drainage systems.

• The guide proposes a four-step process for integrating biodiversity into urban planning: identifying potential species groups before the planning decision, assessing if the application contains sufficient data, conducting inventories, and designing for a diverse biological community.
• To guide the design of biodiversity, the document suggests a four-level priority hierarchy: enrich, preserve, mitigate, and replace. The primary goal is to enrich existing biodiversity and improve the state of the environment on the site.
• The 'Planning Green Factor' (PRF) is a tool used to calculate the ecological value of a plot by assigning coefficients (0 to 1) to different surface types. Hard surfaces like asphalt receive a 0, while natural vegetation receives a 1. For new development areas, a minimum PRF value of 0.5 is recommended.
• To improve the quality of the Green Factor, the guide introduces 'Green Points' (PRP), a list of 30 specific biodiversity-promoting activities from which 10 should be selected and implemented. Examples include installing bird boxes (one per two apartments) or creating bat boxes.
• The guide identifies specific requirements and protection measures for key urban animal groups: pollinators (requiring nectar-rich plants and flower meadows), amphibians (requiring 'frog-friendly' ponds and tunnels), reptiles (requiring shelters and south-facing slopes), bats (requiring old hollow trees and specific roosts), and birds (requiring nesting boxes and diverse vegetation).
• Sustainable Urban Drainage Systems (SuDS) are recommended to manage rainwater at the source, mimicking natural wetlands to reduce the load on sewage systems and mitigate the 'heat island' effect. These systems can include green roofs, infiltration areas, and ponds.
• Green roofs are categorized as either extensive (thin substrate 6-12cm, low maintenance, primarily sedums) or intensive (thick substrate 20-40cm, high maintenance, diverse plants). Extensive roofs are more common due to their lighter weight and suitability for existing buildings.
