Often without meaning to, quarries provide collections of different sorts of landscape features and vegetation that many animals live in. 


Unfortunately, the presence of some wild animals may also be bad for business. This is because many of the animals that seek shelter in our quarries are rare, and therefore legally protected. 


If a legally protected wild animal colonises an operational area of a quarry they may make it difficult or, in extreme cases, make it uneconomical to work those areas.


In recent years, several quarries have had to delay operations due to the presence of legally protected wild animals. In a small number of cases quarries have had to spend tens and even hundreds of thousands of pounds in order to work round legally protected animals to avoid disturbing or killing them, or damaging the features and vegetation in which they live. This has included situations where legally protected animals have colonised operational areas bringing production to a halt, or colonised worked-out areas, preventing buildings and plant from being decommissioned and restoration from being completed in accordance with planning permissions.


In most cases, this was due to legally protected animals moving into features that the quarry had made, sometimes only temporarily. 


AEcol have been solving long-term problems and attending to urgent issues that might otherwise have slowed and even stopped production in quarries for nearly 20 years. Whilst it is a lucrative line of business, we are great believers that prevention is better than cure; better for our clients margins and better for our long-term relationship with our clients.


We therefore offer a day course for Quarry Managers and Foremen that equips them with a working knowledge of which legally protected species may turn up in a quarry, and very simple steps the quarry staff can take to discourage the species from colonising operational areas during the life of the quarry, and also what to do if they suspect they may have a problem.


Our ‘Protected Species Housekeeping Day’ comprises a series of six short modules in the classroom and then a walk round an operational quarry of the clients choosing in order to identify any improvements that might be made to guard against the potential for conflict.

AEcol Principal Ecologist Henry Andrews is a specialist in woodland bat ecology and an experienced trainer who has helped many organisations fill in gaps in their knowledge.


AEcol Training - We won't teach you the methods for searching, we'll teach you the methods for finding


As the author of Bat Tree Habitat Key Henry has a comprehensive knowledge of tree-roosting ecology and can teach you how to identify all the Potential Roost Features (PRF) present in and on trees.


He can explain how each PRF forms, and teach you where they form on the tree and how to search for them. He can show you how the individual bat species use each PRF. He can show you how to survey for tree-roosts in woodlands using field-craft that you probably already possess, but just need to put into context. He can demonstrate practical methods for PRF mapping, assessment and repeat survey. He can show you not only how to find bats in PRF using torches and endoscopes, but which field-signs are reliable indicators of past presence when there are no bats present on the day you look.


So, whether you're a forest manager, woodsman or woman, an arborist or an ecological consultant, Henry can provide you with sufficient knowledge to be confident of finding bats in trees for yourself. 


At the moment, we offer a three-day course in Somerset that focusses in depth on all aspects of tree-roosting ecology and survey. Each day comprises class-room talks and field-based exercises visiting and inspecting a wide variety of roosts used by a wide variety of bat-species. You'll be equipped with lots of helpful reference material (all with practical application in mind), and closely assessed so we can test what you have learned and we can fill in any gaps. The course has a maximum of 12 participants and two full-time instructors.
