Biodiversity Solutions

About Us

Biodiversity Solutions was established in 2009 by a group of self-employed ecologists in West Wales to act as their marketing and office portal and to seek to put something back into conservation in the area. The company is a non-profit making social enterprise whose income is derived from a small charge to ecologists for the services provided and any surplus is dedicated to conservation projects.


The office, manned by Sally Archer-Thomson an Environmental Science graduate, is based near Haverfordwest in Pembrokeshire and will always deal with enquiries promptly and engages with ecologists on a daily basis. The office issues invoices on behalf of ecologists and supports their general office requirements.
