Tranen is always on the lookout for new techniques where traditional methods do not work, or may be improved upon. With two PhD’s on our small team, we are able to incorporate scientific principles into all of our projects. With data collected from over 700 different projects we are able to constantly refine our practices to achieve optimum outcomes no matter what the constraints.

Research and development

Tranen has been involved in many research projects for clients, of our own initiative, and with industry associations, particularly RIAWA.  We are very keen to expand our knowledge base, and are always on the lookout for better ways of doing things.

Intervention ecology and novel ecosystems

The basic premise of intervention ecology is that, because of various factors, primarily climate change, active intervention into ecosystem dynamics may be required for the continuation of ecosystem functions.  Many ecosystems are now sufficiently altered in their structure and function to qualify as “novel ecosystems”, incorporating whatever abiotic and biotic components are available, and this should be the starting point for restoration projects. Thus when planning to restore an area to its original condition, it may be difficult to determine exactly what the original condition was, and traditional restoration techniques may not be entirely appropriate, with innovative techniques required.


In addition to providing practical hands-on field training, Tranen is also able to offer more comprehensive classroom-based and/or field-based education and training covering more theoretical aspects of ecological restoration.  For example, Tranen staff have delivered presentations at university landscape architecture student workshops, as well as leading such students on visits to sites where Tranen staff have been involved in large-scale restoration experiments.
