The following is a list of the core services we provide. However we are not strictly limited to these so please contact us to discuss any arboricultural or ecological requirements you may have.
Extended Phase 1 Habitat Surveys
The baseline survey designed to establish the potential ecological significance of a proposed development site. Target notes will identify any ecologically significant features. Such features may then be the subject of detailed ecological investigation.
Protected species risk assessments
These assessments are used in conjunction with phase 1 habitat surveys and also include data searches for known protected species records. Species and groups covered include: Bats, Great Crested Newts, Otter, Water vole, Badger, Red squirrel, Birds and Reptiles.
We undertake bat surveys for planning purposes on a range of projects including loft conversions, barn conversions and demolitions. This involves full building inspections by licensed bat workers and activity surveys, when required, using experienced surveyors. We use heterodyne, frequency division and time expansion bat detectors along with digital recording equipment for post survey analysis of bat calls. Dendra currently has three ecologists licensed to carry out bat surveys.
Great Crested Newt surveys
We undertake Great Crested Newt surveys for planning purposes. This involves habitat suitability assessments, torch surveys, bottle trapping, egg searching and netting. Dendra currently has two ecologists licensed to carry out Great Crested Newt surveys.
Other protected species surveys
With a number of ecologists present at Dendra we have the capacity to carry out a wide range of other protected species surveys including Otter, Water vole, Badger, Red squirrel, Reptiles and Birds. Please contact us for more information.
Bat mitigation licensing
Our staff have held a number of bat mitigation licences over several years and have the experience required to act as the ecologist on licensable projects. Barry Anderson is a Registered Consultant of the new Bat Mitigation Class Licence (bat low impact class licence). This licence streamlines the licensing process for certain works that are deemed to have a low impact on certain bat species. This has the potential to reduce the paperwork, timescale and cost associated with bat mitigation licensing.
Aerial tree inspections for bat roosts
We can undertake detailed aerial inspections of trees using trained climbers and Mobile Elevated Work Platforms (MEWP). Features of trees likely to be utilised by bats can be inspected in detail with the use of endoscopes. Evening emergence and/or dawn entry surveys can also be undertaken if evidence of bat usage is found.
Ecology reports for BREEAM purposes
We have the experience and qualifications necessary to undertake ecology surveys for projects requiring credits under BREEAM
