News of a continued decline in house sparrow numbers was released last week by the British Trust for Ornithology (BTO). As a London and UK Biodiversity Action Plan (BAP) species they are a material consideration in the planning process across the capital. New findings are likely to firm up local planning authorities’ approach regarding mitigation and enhancement for birds. This needn’t mean significant impact or constraint over design or cost for your building however with many cost effective means for enhancing development for birds readily available. Surveys for breeding birds will need to be scheduled in for spring to coincide with the beginning of the nesting season. To discuss surveying or mitigating for birds, or any wider issues regarding biodiversity and built form, contact our senior ecological consultant Morgan Taylor on 0203 544 3995 or at firstname.lastname@example.org.
