Some interesting comments here but a bit of a concentration on funding and money. The quoted section in the original question actually highlights that spending money isn't necessarily the answer. My council has an environmental policy which requires the council to consider the environmental impact in the decisions it makes. So, for example, comments on planning applications can include comments on the environmental impact of any development proposals, we require grant recipients to confirm how they will support biodiversity within the project they are requesting funding for and we have a management plan for the open spaces we manage which encourages wildlife etc. There is a group of councillors who monitor projects etc. and produce an annual report, making suggestions for improvement or change. Small steps I know but for a parish of our size, all with a positive impact.
