My Lords, I understand that Amendment 46 is not central to the thrust of the Bill but it will definitely improve it, although perhaps as a bit of a side issue. The amendment seeks to do more than just preserve ancient trees, of which we have heard so much about and which are extremely important; in subsection (1)(d) it also provides for new plantings. The need for trees on development sites is extensive in order to improve the otherwise sterile environment that is often found on a new estate.
Trees improve the townscape by breaking up angular building forms. They bring colour in season, they screen unsightly views and enrich biodiversity and habitats. They benefit insects, birds and mammals, and provide a source of nectar for bees which are currently under much pressure from chemicals. They also provide berries for wildlife. Trees conserve energy by providing shelter and shade from the wind and the sun. They absorb pollution and particulates and thus improve air quality, which is an increasing urban problem leading to ill health and sometimes death. Trees can provide educational tools for schools in order to develop environmental awareness and conservation skills. The list of benefits is long and worthy—from the abstract by reducing human stress, to the practical by absorbing and mitigating the risks of flooding and erosion, as we have heard.
However, trees have to be managed and there are health and safety aspects to be addressed. For example, branches can sometimes shed without warning, but these are not too difficult to manage. If we had more trees, children might even rediscover the joys of climbing them and they might learn to respect and not to vandalise their own communities by damaging the young plants. This alone can foster strength in communities and reconnection with neighbours.
If carried, this amendment would add greatly to the Bill in an inexpensive and non-critical way. I commend it to the Committee.
