Veteran & Ancient Trees

Ancient trees are recognized as irreplaceable assets that are vital to wildlife as well as our own sense of identity.

As trees reach the later parts of their age span and beyond, their management and safety require more specialised guidance. Our team are experienced in managing aging tree populations and their varying conditions and unique requirements. We can offer guidance on their management, to ensure where possible that the trees to continue to provide their benefits as historical landscape features as well as the benefits to wildlife for many years to come.

Trees & the Law

There are extensive laws which control the trees and woodlands to ensure their safe retention and protection.

With wide-ranging experience in this field and extensive academic knowledge, we are able to provide advice across a wide array of tree subjects, whether it is advice on planning appeals, felling licences, hedgerow mediation, or TPO tree work applications we are able to advise and assist.

Trees & Development

Developing near trees? Too often trees have been seen instead as barrier to development, we take the approach that planning should take place with the presence and the benefits of trees as a given.

Their assessment and the identification of their value to the site and the wider locale is also important when considering their retention potential, and the protection requirements (throughout development). Working cooperatively with you, allows us to in successfully consider trees in the planning and design process and can often be critical to a successful outcome of planning decisions.

We can be called upon to help with anything from a simple desktop assessment and general advice to a full suite of Impact Assessment and Method Statements, on-site supervision,  Landscape design & planting, and also aid in finding technical solutions to more advanced schemes.

Tree & Woodland Management

From recommendations on tree planting, management and condition surveying, to landscape restoration and managing vegetation on both large and small-scale projects, our dynamic advisory services cover every aspect for individual tree and woodland management and are delivered to the highest of modern industry standards.

Planning & Landscape Conditions

When Planning Permission is granted, the Local Planning Authority (LPA) often require additional information is submitted as a Planning Condition. We can aid in the successful meeting and discharge of conditions linked to tree protection and retention.

Working with our in-house landscape architects, we can also offer tailored tree planting and landscape schemes, and offer design and advice to not only improve your sites landscape and function, but also aid in its establishment.

Visual Tree Assessments & Tree Risk Management

Tree owners have a legal ‘duty of care’ to take reasonable steps to ensure the safe condition of their trees. Whether it is a singular tree or a whole estate, we can efficiently assess by Visual Tree Assessment (VTA) the condition of the trees.

These assessments provide clear information on the general condition of the tree, its health and vitality. This enables us to advise you with current and potential future works to help maintain or improve the condition of trees and their relative safety in a controlled and structured approach, which will aid in reducing your long term expenditure and improving the benefits of the trees.

Gauging station evaluation, relocation and design

We have significant expertise in designing and installing flow gauging stations, including modifications of existing gauging stations to facilitate fish passage (e.g. through retrofitting of baffles or adding a Larinier fish pass in compound with an existing gauging weir). We can advise on siting, choice of method/feasibility and design. We have also excellent working relationship with NIVUS GmbH, with whom we have worked closely in designing new transit time ultrasonic stations.

Strategic studies and network reviews

We have an impressive track record in relation to delivering strategic hydrometric studies:

  • From January 2007 to September 2010, we carried out an extensive national review of the hydrometric network in England and Wales on behalf of the Environment Agency. The work was undertaken in two phases: i) River Gauging Network, ii) Rainfall Gauging Network. As well as a comprehensive review of the existing network and assessment of requirements to meet future initiatives, software tools for and guidance on network management were developed.[1]
  • From September 2008 to June 2010 we carried out a strategic review of Hydro-Meteorological Monitoring networks operated by the Office of Public Works in Ireland. This involved the identification of the long-term strategic needs for flood-related hydrometric and meteorological data in Ireland, including strategic management requirements for effective data collection and provision of flood related information.
  • In 2012 we carried out a detailed review of the Hydrometric Network in Yorkshire and North East, whilst involved a review of drivers of the flow and level gauging network, quantification of benefits derived from the network and outline of possible network improvements, specification of gaps and redundancy in existing network and prioritisation for network improvements based on operational requirements.
  • In 2015 we delivered a detailed review of the hydrometric network operated by the Environmental Protection Agency in Ireland. This included a detailed comparison of the hydrometric network in Ireland with those in Scotland, Wales and New Zealand.
  • We are currently (2018) helping Waterways Ireland to undertake an evaluation of their monitoring network.

[1] See Davis, R., Zaidman, M., Grew, R. & Garrett, K. 2010. Evaluating the benefits of the hydrometric network in England and Wales. Proceedings of the British Hydrological Society Conference, Newcastle University, July 2010.

Hydrometric data validation and review

All the data we collect and supply undergoes strict validation and data assurance processes before use/issue. We are also able to undertake independent validation or checks of third party data; a recent example being an independent review of the quality of hydrometric data collected by the Tweed Forum as part of their Eddleston Water Project.

Our team has been widely involved in defining procedures for data management and assessment of data quality, of which some of the higher-profile projects have included:

  • Development of Operational Instruction outlining how the HiFlows-UK flood peak database should be managed, and implementation of improvement measures including rating updates and evaluation (Environment Agency, 2014).
  • Derivation of a classification scheme for gauging station data quality assessment (referred to as GSDQ) on behalf of the Environment Agency in 2002 and subsequent improvements, modifications and enhancements.
  • Reviews of the performance of the EA’s Tipping Bucket raingauge network, which included comparing accumulated rainfall from TBRs and their collocated storage raingauges and identifying reasons for any discrepancies in terms of calibration, site maintenance, under catch due to exposure, evaporation etc.
  • Development of a tipping bucket raingauge calibration procedure for the OPW.
Spot gauging service and rating curve development

We offer a spot gauging service using our own Valeport Model 801 Electromagnetic Open Channel Flow Meter, which we operate in accordance with BS EN ISO 748:2007 and which undergoes calibration every three years by the manufacturer. Recognising those situations where specialist equipment is needed we also have expertise with hired instrumentation including OTT’s QLiner, Sontek’s RiverSurveyor and FlowTracker devices and RD’s Stream Pro ADCP.

We have carried out flow gauging for Natural Resources Wales, Essex and Suffolk Water, National Trust and Irwell Rivers Trust, Aire Rivers Trust, South East Rivers Trust and the Environment Agency as well as private clients (e.g. in support of hydropower assessments, abstraction licence applications, internal drainage boards/water level management plans).

Our team is highly experienced in the development of new, and in the reviewing of existing Stage-Discharge and Velocity-Index ratings. We use our innovative in-house applications to aid hydrometric data review and analysis. To date we have derived over 100 new stage-discharge ratings on behalf of the Environment Agency. We also run training courses on the topic of extrapolation of high flow ratings and use of modelling to extend high flow rating limbs.

Training and support

We are expert trainers in hydrology (our team runs the foundation and advanced level training courses offered within the Environment Agency).  We offer a range off-the-shelf courses covering theoretical and practical aspects of hydrological analysis but are equally able to provide tailored training based on real case studies and practical examples.
