RESEARCH

My research has always had two clear goals; i) to advance understanding of how to create ecologically based plant communities in landscape practice, and ii) to develop and test theoretical understanding of the key phenomena involved.  I have always tried to publish as much of my research as possible (although never as much as I would like) in order to build a scientific literature, particularly in relation to developing ecologically based, designed plant communities, to avoid re-inventing the wheel in the future.

I have maintained a plural approach to research design and analysis, employing the techniques which seemed best fitted to the work in question.  Given that my work deals with both quantitative ecology-horticultural science and social science, this has involved a very broad spectrum of approaches.

Much of my Ecology-Horticultural Science research has been based around understanding how species rich designed plant communities can be made and managed, and which species persist and which do not, and how environmental and management regimes affect this.  My work typically involves the creation of plant communities by sowing seed in situ, mirroring in some ways research with purely native plant communities in “Restoration Ecology”.

To date I have worked on the following plant community types:

My standard approach has often been to develop understanding of the germination and emergence ecology of the key species, often starting at the growth cabinet scale and then moving to field emergence studies working in monoculture.  The next step has been to create microcosm communities which are then subjected to various environmental and management factors with the outcomes recorded over as many years a possible.  Some of these latter experiments closely parallel what happens in commercial field scale practice.


Work on a new plant community often starts within the controlled conditions of a growth cabinet.  The experiments shown here establish the number of days different species take to germinate.


Once germination characteristics in the lab are understood, the effect of moisture regime on emergence in the real world are explored.  This experiment is in Germany in conjunction with Jelitto Seeds, and established the typical % emergence of almost 1000 different species across a range of moisture gradients.


Once individual species are sufficiently well understood, model research communities of  species can be created and then used to test interactions between species over long periods of time, mimicking what happens in the real world of practice.


In doing this research I have collaborated with a number of organisations, however mostly I have worked with the Royal Horticultural Society, at both RHS Wisley and RHS Harlow Carr.
