As always….
There is a great deal more to unpack here than the original question sets out.
Firstly, the original question seeks to address the perceived circumstance of a Cllr “abusing their position” and “losing their way as a Cllr.”
Is this the correct starting premise or is this an example of seeking to address the (perceived) symptom rather than the actual cause?
Who is it that “perceives” the Cllr to be “abusing their position” and “losing their way as a Cllr?”
Is it a clerk, a council chair, a fellow Cllr or a member of the public presenting the question?
Not that it particularly matters since none of those are entitled nor empowered to make such an assessment.
Rather than address the question as presented, I will set out some (of what I consider to be) useful scene setting - some based upon assumption, some based upon personal experience of PC behaviour and some based upon quantified and qualified professional opinion as a suitably qualified and experienced professional tree inspector, a qualified quantified tree risk assessor and an experienced professional arboricultural consultant.
Ash dieback is a better starting point rather than the perception of a Cllr’s behaviour.
There is a wealth of current, scientifically informed, risk based advice and guidance available from highly reputable, independent, government and NGO organisations in relation to land owner responsibilities for tree(s) affected by Ash dieback (Hymenoscyphus fraxineus.)
Ash dieback - That’s your starting point and it really isn’t as “terrifying,” nor worthy of knee jerk over-reaction as some might seek to suggest.
If your tree survey was conducted by a suitably qualified tree inspector it is likely that the recommendations will have been informed by industry standard visual tree assessment and an awareness of the quantified risk posed by the tree(s.)
If it isn’t, then what you may have is the “opinion” of somebody that may benefit from what is known within the arboricultural world as “risk entrepreneurship” ie, the person making the recommendation stands to benefit from the implementation.
Is your tree survey supported by qualification such as the LANTRA Professional Tree Inspector qualification and supplemented by adqual’s such as Quantified Tree Risk Assessment or VALID Tree Risk Management?
Is your council aware of the National Tree Safety Council guidance on Common Sense Management of Trees for landowners (another genuinely well produced and presented online resource) or current Forestry Commission or government guidance on ADB?
If no - it is more likely that you may have risk entrepreneurship in what you refer to as a ‘tree survey’ which may not be worth the paper it is written on.
Even if it is, and if anybody takes the time to research the highly credible open source information widely available online, it will become obvious that felling is only 1, particularly extreme, option in a raft of lesser options which have far greater biodiversity benefits.
Occupation rates of the impact area is a key factor and there are several options, less than felling, which may be quantifiably more suitable and cost effective.
Crown reduction, removal of specific hazard limbs, retention of a standing stem as biodiversity habitat are just a few ‘lesser’ options which present considerable biodiversity AND cost saving benefits - these are rarely presented by the risk entrepreneur and councils rarely have the experience, expertise nor capacity to properly understand this.
If, all of the above has been properly considered (and personal experience of local council behaviour leads me to seriously doubt that) and your ‘tree survey’ is from a credible source, then just maybe the subject Cllr might be an over zealous environmentalist.
If none of the points presented above have been properly and appropriately assessed by the council, then, just maybe, rather than a single Cllr “abusing their position” and “losing their way as a Cllr” what you might actually have is a lone voice of diligent sanity in a council which lacks true environmental awareness and responsibility for appropriate stewardship of public money and land assets.
What you might actually have is what all councils should cherish and value - a well intentioned and enthusiastic member of a team that is frustrated by their perception of a corporate lack of attention to detail resulting in some desperate attempts to rally support for a worthy cause but which has upset the establishment.
Food for thought.... I've made a lot of assumptions, but I'll be surprised if much of that is wildly off the mark.
"We do not wish to quash this councillor's passion". Who is this "we" you speak of and on what authority?
