How James Blake Associates can help you

View all services


A comprehensive and informative tree and hedgerow appraisal service.

We pride ourselves on the production of clear and accurate information, and the delivery of comprehensive and innovative arboriculture advice. Our highly qualified team, led by Kevin Slezacek, has over 50 years combined experience in commercial, contracting, and public sector work.

Our team has first rate arboricultural knowledge and relationship building skills, and consistently ensure pragmatic, good-practice solutions for clients. Our testimonials demonstrate this prowess.

The benefits of tree retention to development are now widely publicised. A key part of our service is to identify those worthy of retention and to provide methods of work that will ensure we keep as many existing good quality trees as possible, whilst meeting our clients’ individual needs. Existing trees can help developments maintain that vital curb appeal.

Development can be achieved in close proximity to trees quite successfully, providing the correct approach is taken. Our experience in using innovative construction methods to avoid root damage has been used on a number of sites. However, some trees will always need to be removed to make layouts and land uses work.  Kevin and his team can demonstrate how this will work and how lost trees can be replaced, often to longer-term site net benefit.



Our arboriculture services include:

  • Pre Purchase Assessments
  • Initial BS:5837 Tree Survey
  • Constraints Plan and Report
  • Implications Assessment and Method Statement
  • Tree Protection Plans
  • Liaison with LPA tree officers
  • PiCUS™ decay assessment
  • Inspection Monitoring for tree works and throughout construction
  • TPO Applications
  • Management plans including woodland management plans

It is often perceived that trees and hedgerows are constraints within the landscape, but we can provide advice which maximises development space and tree retention.  This provides instant maturity and amenity value and reduces the environmental impact.

Trees that need to be lost can be replaced, and the arboricultural team will advise the landscape team on tree choice and location.
