The design of Bow Common Gasworks takes an ecology led approach to enhance and join up the ecological network of the area. This strategy documents the initiatives to ensure Bow Common Gasworks vastly improves upon the current condition, increases the provision for wildlife, and enhances the connection between ecological sites through wider envi-ronment improvements. Bow Common Gasworks sets out a sustainable and managed approach to ecology that ensures a thriving and connected wildlife population.

At a glance, Bow Common Gasworks proposes a net biodi-versity gain of 60%, a high urban greening factor of 0.4 or above, significant contributions to the council's Biodiversity Action Plan, and developer enhancement objectives including the introduction of habitats specially designed to meet the needs of the council's Biodiversity Action Plan listed species. Spatially, new habitat creation will be formed at ground levels, including up to 10,700 sqm of species rich grassland with calcareous species, and living roofs. In addition to new habi-tats, a cross phase strategy is provided to expand existing habitat species populations into new calcareous grassland habitats.

In due course, a detailed Landscape Maintenance and Management Plan will reflect the detailed ecology provisions brought forward in the Reserved Matters Applications. This document will highlight the vegetation and habitat types, giving specific direction to their needs. As a start, three key vegetation and habitat types have been identified in this strategy and objectives outlined.

The structure of this strategy includes the following chapters:

• Ecology Led Approach

• Contributing Towards the Objectives of the Local Biodiversity Action Plan (2019-2024)

• Biodiversity Net Gain

• New Habitat Creation at Bow Common Gasworks

• Management and Maintenance Approach

• Briefing Note on Small Blue Butterfly

MAKING SPACE FOR NATURE/ LAWTON REPORT, 2010 MORE, BIGGER, BETTER, JOINED UP

"The essence of what needs to be done to enhance the resilience and coherence of England’s ecological network can be summarised in four words: more, bigger, better and joined. There are five key approaches which encompass these, and also take account of the land around the ecological network. We need to: (i) Improve the quality of current sites by better habitat management. (ii) Increase the size of current wildlife sites. (iii) Enhance connections between, or join up, sites, either through physical corridors, or through ‘stepping stones’. (iv) Create new sites. (v) Reduce the pressures on wildlife by improving the wider environment, including through buffering wildlife sites."

"Overall, bigger is better, and creating new wildlife habitat will move the network in the right direction."

"...in areas which only have small and isolated sites, it will be better to invest in the restoration and creation of new wildlife habitat."

"In general, the first priority is to enhance the quality of remaining wildlife habitat. Increasing connectivity helps, but first there needs to be high quality sites with thriving wildlife populations to connect."

CONSIDERATION OF THE LOCAL BIODIVERSITY ACTION PLAN

"Tower Hamlets is a densely built-up borough, and over one third of its area is occupied by buildings, streets and car parks. The built environment can be surprisingly rich in wildlife. Buildings provide roosts for bats, and nest sites for birds which more traditionally nest on cliffs. These include the spectacular peregrine falcon and the rare black redstart… We can enhance the built environment for wildlife in many ways. Green roofs are the easiest place to replace our disappearing brownfield (open mosaic) habitats. Buildings can be enhanced for bats and birds by providing custom-designed nesting and roosting sites, either built into the fabric of new buildings or retrofitted to existing ones. Climbers and other forms of green walls can provide nectar for bees and nesting sites for our declining house sparrows. And streets can be greened with trees, hedges and planters full of nectar-rich flowers."

TowerHamletsLocalBiodiversityActionPlan2019-2024,BuiltEnvironmentActionPlan

"Almost 40% of the area of Tower Hamlets is occupied by gardens and the landscaped areas around housing estates, schools, businesses and other premises. By far the majority of this is housing amenity land. In the last few years, social housing providers and residents in Tower Hamlets have created some excellent wildlife habitats, such as meadows, copses, hedges, orchards and nectar-rich community and communal gardens, around housing estates..."

Since the beginning of the design process, Bow Common Gasworks has sought to meet the objectives of the Tower Hamlets Biodiversity Action Plan (inparticular,thosesetoutintheBuilt EnvironmentandtheGardens & Grounds Action Plans), by contributing to the priorities, targets, and to help meet the needs of the relevant LBAP species.

GREEN ROOF HABITAT CREATION + COLONISATION MODULAR CASSETTE SYSTEMS

Modular green roof cassette systems can be used to encourage themigrationofspeciestogreenroofhabitatsthatwouldotherwisenotbeableto.Further,theyprovidea'meanwhile'formofhabitatcreationthatfillsinthegapsthatwouldusuallyoccurduringtheconstructionphaseofadevelopment.

HABITAT CREATION STRATEGY COLONISATION OF EXISTING SPECIES

PHASE 5 PLOT

HABITAT NURSERY

Location of green roof 'nursery' in full sun and away from potential disturbance. The area shown in yellow is approximately 1100m2, which is equal to the total area of green roof in phase 1.

Cassettes are filled with an extensive green roof substrate and seeded with a suitable mix of species (potentially harvested from a nearby source such as Scrapyard Meadows).

This is to commence the autumn before phase 1 construction begins.

The cassettes are then to be installed on roofs at the appropriate time of year.

21


PHASE 1

PHASE 2 CONSTRUCTIONc. AUG 2024 - SEP 2027

Green roof cassettes that were seeded prior to the construction of phase 1 are installed.

PHASE 5 PLOT

New green roof cassettes replace the ones that have been relocated to Phase 1 rooftops. The same process of seeding, maintenance and relocation is repeated.

After the completion of phase 1, the cassette system would not be intended to fill all living roofs. It would be one part of a wider mosaic of habitat creation using more traditional methods. This would ensure a better variety of calcareous grassland habitat (degrees of openness, variety of substrate depths etc...). The amount of cassettes used in subsequent phases will be subject to the development of a more in depth strategy.

It is the intention to bring the park forward as quickly as possible. The diagram above illustrates the current phasing strategy considering all construction, access and remediation constraints. This is subject to change if areas of the park are able to be completed sooner.

MANAGEMENT AND MAINTENANCE APPROACH

The establishment and future success of the landscape is largely dependent on the standard and frequency of the maintenance and management it receives.

Key objectives for maintenance and management include:• To facilitate an efficient and sustainable landscape management and maintenance regimethatevolvesthroughthelifetimeofthedevelopment;• To ensure that the landscape develops in amannercommensurate with the original design intentions;

•Toprovideasafe,high quality external environmentforallusers;

•Topositively welcome people into the Common,physicallyandsocially,whilstbalancingthedesiretoprovide a haven for wildlife;•Toensurethesuccessful establishmentandcontinued growththroughtomaturityofthetreesandotherplantingidentifiedintheLandscapeProposals;•Tocontribute to the value of the surrounding green infrastructure,andtohelpprovide linkswith thewidergreengrid;•Toenhance the ecologyofthesiteandimprove local biodiversitywhereverpossible;

•Andtolearn from the excellent and sustainable precedent set by the Tower Hamlets Cemetery Park’smanagementandmaintenance.
